A review of staphylococcal Endocarditis

VG Fowler Jr, Miro JM, Hoen B, et al for the ICE Investigators. Staphylococcus aureus endocarditis: a consequence of medical progress. JAMA. 2005;June 22;293(24):3061-3062.

Agroup of infectious diseases experts from centers throughout the world formed the International Collaboration on Endocarditis (ICE) in 1999 to gain a global understanding of infective endocarditis. Using the Duke Criteria patients with definite infective endocarditis in a prospective manner, 275 variables were reported with these cases to a central database maintained at Duke University. The ICE-Prospective Cohort Study (ICE-PCS) enrolled 1,779 patients with infective endocarditis in 39 centers in 16 countries between June 15, 2000, and December 31, 2003, and has been described in a recent report. (Cabell CH, Abrutyn E. Infect Dis Clin North Am. 2002;16:255-72). Staphylococcus aureus was the most common cause of infective endocarditis in this group of patients (n=558; 31.6%); the authors characterized risk factors and clinical issues associated with these cases in this report.

By univariate analysis, compared with non-Staphylococcus aureus infective endocarditis, patients with infective endocarditis due to Staphylococcus aureus were more likely than patients with infective endocarditis due to other pathogens to be female (P<0.001), hemodialysis dependent (P<0.001), have diabetes mellitus (P=0.009), have other chronic illnesses (P<0.001), have a healthcare association (P<0.001), have higher rates of stroke (P<0.001), have systemic embolization (P<0.001), have persistent bacteremia (P<0.001), or die (P<0.001).

Although healthcare associated Staphylococcus aureus infective endocarditis was the most common form of Staphylococcus aureus infective endocarditis, more than 60% of healthcare-associated patients acquired the infection outside the hospital. This reflects the global trend in healthcare delivery patterns favoring ambulatory treatment (e.g., outpatient medication infusion via long-term IV access, hemodialysis)

Multivariate analysis, clinical features independently associated with Staphylococcus aureus infective endocarditis (versus non-Staphylococcus aureus infective endocarditis) were: IV drug use (OR, 9.3; 95% CI, 6.3-13.7); first clinical presentation less than one month after first symptoms (OR, 5.1; 95% CI, 3.2-8.2); healthcare-associated infection (OR, 2.9; 95% CI, 2.1-3.8), persistent bacteremia (OR, 2.3; 95% CI, 1.5-3.8), presence of a presumed intravascular device source (OR, 1.7; 95% CI, 1.2-2.6), stroke (OR, 1.6; 95% CI, 1.2-2.3), or diabetes mellitus (OR, 1.3; 95% CI, 1.1-1.8).

Patients from the United States with Staphylococcus aureus infective endocarditis were more likely to be hemodialysis-dependent, to be diabetic, to have a hemodialysis fistula or a chronic indwelling central catheter as a presumed source of infection, and to have a non-nosocomial healthcare association. Patients from the United States and Brazil were more likely to have Methicillin-resistant Staphyloccocus aureus (MRSA) than were patients from Europe, the Middle East, Australia, or New Zealand. In-hospital mortality rates were similar across regions, although American patients were significantly more likely to develop persistent bacteremia (25.6%, P<0.001).

Characteristics independently associated with mortality among patients with nonintravenous drug-use-associated Staphylococcus aureus infective endocarditis by multivariate analysis included stroke (OR, 3.67; 95% CI, 1.94-6.94), persistent bacteremia (OR, 3.06; 95% CI, 1.75-5.35), diagnosis in Southern Europe or the Middle East (OR, 3.21; 95% CI, 1.17-10.56).

This study establishes Staphylococcus aureus infective endocarditis as the leading cause of infective endocarditis in many regions of the world and spotlights the global emergence of healthcare contact as a risk factor for Staphylococcus aureus infective endocarditis. In a significant portion of these patients, an IV device was the presumed source of bacteremia; prosthetic cardiac devices (pacemakers, defibrillators, or prosthetic cardiac valves) were present in almost one-quarter of the patients.

MRSA was a significant cause of Staphylococcus aureus infective endocarditis and displayed regional variation, accounting for almost 40% of the infective endocarditis caused by Staphylococcus aureus in some regions. Patients with infective endocarditis caused by MRSA were significantly more likely to have pre-existing chronic conditions and healthcare associated infective endocarditis by both univariate and multivariate analysis. They also were often associated with persistent bacteremia. On the other hand, 20% of patients with MRSA infective endocarditis developed their infection in the absence of identifiable healthcare contact.

 

 

Limitations of this report include the fact that this is an observational study of patients from self-selected centers. Each center most likely represents a portion of the local population, making it difficult to generalize findings to the entire population centers from which this report originates. Represented hospitals were typically referral centers that have cardiac surgery programs and may have widely differing populations with varied risk factors. Advantages include the large size of this prospectively evaluated cohort and the ability to analyze regional variations between continents with a contemporary nature of the patient sample (2000-2003).

This population-based study at a medical center with detailed medical records of virtually all residents of a single county allows us to view the clinical features and etiologic factors of primarily left-sided infective endocarditis without the referral bias that tends to taint other studies typically published out of large medical centers with larger geographic referral bases.

Infectious Endocarditis in Olmsted County, Minn.

Tleyjeh IM, Steckelberg JM, Murad HS, et al. Temporal trends in infective endocarditis: a population-based study in Olmsted County, Minnesota. JAMA. 2005;293:3022-3028.

Tleyjeh and colleagues at the Mayo Clinic in Rochester, Minn., retrospectively studied 102 cases of infective endocarditis that occurred in 107 Olmsted County residents from 1970-2000. Main outcome measures were incidence of infective endocarditis, proportion of patients with underlying heart disease and causative micro-organisms and clinical characteristics. The records of all Olmsted County residents with infective endocarditis were identified and reviewed in detail. The definite and possible infective endocarditis cases as defined by modified Duke Criteria were used in the analysis.

The age- and gender-adjusted incidence of infective endocarditis ranged from 5.0 to 7.0 cases per 100,000 person-years during the study period and did not change significantly over time. There were 84 (79%) cases of native valve infective endocarditis and 23 (21%) cases of prosthetic valve infective endocarditis. Valves involved: aortic—36 (24%); mitral—49 (46%), aortic and mitral—12 (11%), right-sided or bilateral—8 (7%), or unknown—8 (7%). 16 (15%) had valve surgery within 42 days and the six-month mortality was 26% (n=28).

Infective endocarditis is a disease of the older individual in this population, with a mean age ranging from 54.1 years in 1980-1984 to 67.4 years in 1995-2000 (P=0.24 for trend). There was a male predominance (67%-83%), which did not significantly change over time.

Mitral valve prolapse was the most frequent underlying valvular heart disease. Viridans streptococci were the most common causative organisms (n=47; 44%) followed by Staphylococcus aureus (n=28 cases; 26%).

The overall average crude infective endocarditis incidence of the period 1970-2000 was 4.95 per 100,000 person-years. The age- and gender-adjusted annual incidence was 6.06 per 100,000 (95% CI, 4.89-7.22). There was no time trend for either streptococcus or Staphylococcus aureus infective endocarditis: the annual adjusted incidence of viridans group streptococcal infective endocarditis was 1.7 to 3.5 cases per 100,000 person years while Staphylococcus aureus infective endocarditis had an annual adjusted incidence of 1.0-2.2 cases per 100,000. The incidence rates of viridans group streptococcal and Staphylococcus aureus infective endocarditis have not changed significantly over time in this population.

Potential limitations of this study include possible incomplete case finding or recognition of the retrospective nature of the case reviews. The homogeneity of the patient population studied (primarily elderly white males with a low prevalence of intravenous drug use) limits the ability to generalize the results. Advantages include the fact that this is a population-based study at a medical center with detailed medical records of virtually all residents of a single county. This allows us to view the clinical features and etiologic factors of primarily left-sided infective endocarditis without the referral bias that tends to taint other studies typically published out of large medical centers with larger geographic referral bases.

 

 

The theory is that if a MET responds to see a patient who is becoming unstable, early interventions may reduce the likelihood of arrest.

Computers and Adverse Drug Events

Nebeker JR, Hoffman JM, Weir CR, Bennett CL, Hurdle JF. High rates of adverse drug events in a highly computerized hospital. Arch Intern Med. 2005;165:1111-1116.

Adverse drug events account for a significant number of hospital admissions and the ensuing costs associated with these hospitalizations. Electronic endeavors, such as computerized physician order entry (CPOE), bar code systems, and electronic medical records attempt to reduce the preventable adverse drug events.

Nebeker, et al. attempted to assess the effects of the implementation of CPOE and other computerized medication systems on adverse drug events in a tertiary care Veterans Administration Medical Center. They used an observational study design whereby 937 out of 2,306 newly admitted patients from several hospital wards were randomly chosen and assigned to a pharmacist reviewer during a 20-week period.

They reviewed complete medical records of hospital stays every other day to document adverse drug events. Not only were traditional adverse drug events identified, but harm from overdoses and/or inappropriate dose reductions or discontinuations, as well as intolerable harm from dose titration, were documented as adverse drug events. The harms caused by the drugs were considered only if the drugs were started in the hospital.

Harms were classified based on prior literature and included standards for pharmacological typology, causality assessment, error type, event terminology, drug class, seriousness index, and medication error category indexing. Additional uncommon classifications were also used, including additional resource utilization. Consensus meetings were held weekly to confirm classification of adverse drug events. Of the admissions reviewed, 483 adverse drug events were identified of which 93% were drug reactions while 7% were due to over- or underdosing. Of the drug reactions, 90% were considered dose-dependent while 10% were considered to be idiosyncratic.

Two different indexing scales were used in classifying the harms. Using the LDS Hospital Scale, it was suggested that 91% of the adverse drug events caused moderate harm while 9% caused serious harm. Using the National Coordinating Council for Medication Error Reporting and Prevention indexing, it was suggested that 87% of the adverse drug events fell into category E (requiring treatment) and 4% into category F (requiring prolonged hospitalization). Twenty-seven percent of the total adverse drug events were thought to be due to errors, including execution and planning steps. Sixty-one percent of errors occurred with the ordering mechanism while 25% of the errors occurred in the monitoring process.

This study highlighted rates of adverse drug events five to 19 times higher than baseline. The authors explained this higher-than-expected rate in part by study elements, such as the use of clinical pharmacists as reviewers, iterative case reviews, and accessible electronic data that make adverse drug events more noticeable.

Weaknesses of this study included issues of comparability of CPOEs because there were significant feature differences among commercial software programs. In addition, this was an observational study lacking a control group. The authors felt that their study did not support the idea that the computerized patient record of the study institution had caused adverse drug events. Rather, the study supported the idea that the system increased the visibility of adverse drug events compared with a paper system. In addition, the authors recommended that the choice of CPOEs be carefully considered, with a focus on decision support features when integrated into a healthcare organization.

 

 

The Questionable Benefit of Medical Emergency Teams

Hillman K, Chen J, Cretikos M, et al. Introduction of the medical emergency team (MET) system: a cluster-randomised controlled trial. MERIT study investigators. Lancet. 2005;365:2091-2097.

Previous studies have reported that the MET system reduces the incidence of cardiac arrests, deaths, and unplanned ICU admissions. A MET is a preplanned group of healthcare practitioners who respond to acute patient deteriorations in hospitalized patients.

METs are usually identical to hospital code teams, with the exception that they respond prior to a patient’s developing cardiac arrest. This early response has been shown to significantly decrease unexpected hospital mortality in hospitals in the United States, Australia, and Great Britain. Even though the system has been reported since 1995, few hospitals have knowledge of or experience with METs.

Unexpected hospital deaths and cardiac arrests are often preceded by clinical warning signs. In addition, unplanned ICU admissions may be foreshadowed by abnormalities in the patient’s vital signs that may progress if appropriate interventions are not undertaken. METs assess patients with abnormal physical findings or when there is a concern about the patient’s condition. These patients have findings that may precede a serious event or cardiac arrest, but otherwise don’t meet existing criteria to call a code.

The theory is that if a MET responds to see a patient who is becoming unstable (see “Table 1: MET Calling Criteria,” at left), early interventions may reduce the likelihood of arrest. Published studies have shown a reduction in cardiac arrests and ICU length of stay in virtually all systems in which MET has been introduced (although most studies are hampered by the use of historical controls).

The MERIT study randomized 23 hospitals in Australia to continue functioning as usual (n=11) or to introduce a MET system (n=12). The study sites included a wide range of tertiary, metropolitan, and non-metropolitan hospitals in different states across Australia. The primary outcome was the composite of cardiac arrest, unexpected death, or unplanned ICU admission during the six-month study period after MET activation, using intention to treat analysis.

A four-month educational period was undertaken with the MET centers prior to initiation of the trial. Control hospitals did not receive any education about the MET concept. This was followed by a six-month trial period. Cardiac arrest teams were maintained at all hospitals. The MET consisted of at least one doctor and a nurse from the ED or ICU.

The eligible patients included those residing on a medical ward (including critical care units); the ICUs, OR, postoperative recovery areas, and ED areas were not regarded as general wards.

The primary outcome for the study was the composite outcome of the incidence (events divided by number of eligible patients admitted to the hospital and residing on a medical ward during the study period) of:

  1. Cardiac arrests without a pre-existing “not-for-resuscitation” (NFR) order;
  2. Unplanned ICU admissions; and
  3. Unexpected deaths (those without a pre-existing NFR order).

The results of the study:

  1. During the study period, the overall rate of calls for the cardiac arrest team or MET was significantly higher in intervention hospitals than in control hospitals. Calls not associated with events were more common in MET hospitals than in controls. Half of the total calls were not associated with a cardiac arrest or unexpected death, whereas in MET hospitals more than 80% of calls were not associated with a cardiac arrest or death (P<0.0001).
  2. In patients with documented MET calling criteria in association with cardiac arrest or unexpected death, the call rate was similar in MET and control hospitals.
  3. There were no significant differences between the MET and control hospitals for any outcome.
  4. The response to changes in vital signs was not adequate—even in MET centers.
 

 

These findings are surprising in view of previously reported findings using the MET system. Potential reasons for lack of difference between MET centers and controls include:

  • Number of study sites or the duration of the study may not have been adequate for implementation or education;
  • Hospitals may already be efficient in detecting and managing unstable patients;
  • Patient selection criteria may have been overly restricted. For example, other studies have used 30 respirations per minute for tachypnea as a calling criterion compared with 36 breaths per minute used in this trial;
  • Knowledge of the study may have leaked to control hospitals;
  • Cardiac arrest teams function as METs at times: Nearly half of the calls to cardiac arrest teams in control hospitals were made without a cardiac arrest or unexpected death; and
  • The selected outcomes may not be sensitive enough.

Even though this large, multicenter controlled trial was unable to show a significant benefit of METs, we should not be discouraged from performing further controlled trials in different settings. The use of METs is clearly an exciting and evolving area of medicine.

Barriers to Patient Safety

Amalberti R, Auroy Y, Berwick D, Barach P. Five system barriers to achieving ultrasafe health care. Ann Intern Med. 2005;142:756-764

Patient safety in our healthcare system is a growing concern. One area of dialogue concerning preventable healthcare-associated harms involves the comparability of the healthcare industry with non-medical industries, such as aviation and nuclear power, that have adapted successful strategies shown to provide ultrasafe environments. Amalberti, et al. discuss risk assessment in a variety of industries and explain the need for a benchmarking approach in order to optimize or achieve safety in the healthcare field.

The authors identify five systemic barriers from literature that are fundamentally connected to the ability of the healthcare field to achieve an extremely safe environment.

Barrier 1—acceptance of limitations on maximum performance: The first barrier is the type of expected performance in the field. This is illustrated by the tradeoffs associated with ultrasafety versus productivity. The amount of risk involved was directly related to the limits placed on maximum performance. The first barrier is the acceptance that every system has limits. When a producer exceeds their limit, then safety suffers. An example used is that of blood donation: The limits of collection speed are weighed against the needed screening process.

Barrier 2—abandonment of professional autonomy: The second barrier concerns the concept of professional autonomy. While more teamwork and regulations reduce individual autonomy, this appears to improve safety in the healthcare environment. The bottom line is the importance of teamwork. The example used is that of traffic on a highway: Autonomous units work together to function safely.

Barrier 3—transition from the mindset of craftsman to that of an equivalent actor: The third barrier to achieving high levels of safety includes an equivalent actor mindset. This entails establishing a reliable standard of excellent care in lieu of focusing on individuality, similar to the notion that passengers on an airline usually do not know their pilots, but have established confidence in the airline itself.

Barrier 4—the need for system-level arbitration to optimize safety strategies: The fourth barrier identified is a need for system-level arbitration to optimize safety strategies. This need results from the pressure for justice (usually through litigation) once an accident occurs. Top-down arbitration of safety will be less successful than system level design.

Barrier 5—the need to simplify professional rules and regulations: The final barrier results from the many of layers of guidelines as they serve to create an environment of excellence. This barrier necessitates the removal of these layers to simplify the environment. Existing guidelines should be distilled down to those shown to promote quality and safety. Byzantine rules can obscure the goal of safety and glorify rules, for rules sake.

 

 

Certain structural limitations within the field, such as worker shortages in the face of increasing public demands and the reliance of the field on trainees such as students, interns, and residents, create other hurdles. The authors conclude by suggesting a two-tiered system of healthcare whereby ultrasafety could be more easily accomplished in areas of medicine considered more stable (first tier), and a second tier of care that would include the more unstable conditions, and thus inherently, represent the higher risk situations where errors are more likely to occur.

Another provocative point of this article is the need to move toward educating and training teams—not individuals.

The Importance of Implementing COPD Guidelines

Harvey PA, Murphy MC, Dornom E, et al. Implementing evidence-based guidelines: inpatient management of chronic obstructive pulmonary disease. Intern Med J. 2005;35:151-155.

COPD is a common diagnosis that sometimes requires hospitalization. Evidence-based guidelines for disease management, including that of hospitalized patients, exist, but there is a paucity of knowledge about the actual quality of care delivered in the hospital as it aligns with published guidelines. This study by Harvey, et al. explores the quality of care delivered in the hospital for patients with COPD, while at the same time investigating an intervention for the medical staff in an effort to improve adherence to evidenced-based guidelines of the disease.

Using ICD-10 codes for a COPD diagnosis, the study incorporated a retrospective chart review of 49 hospital admissions prior to the intervention and 35 admissions after the intervention in a hospital in Melbourne, Australia. Data were collected pertaining to the hospital management of COPD as it compared with what the authors considered to be Level A—or the highest level of evidence summarized from several professional organizations. The intervention delivered to the medical staff included a summarized presentation of the results from the initial audit of the 49 charts, as well as an educational package that was given to them following the presentation.

Except for inappropriate use of intravenous aminophylline, of which there was a 100% concordance to Level A guidelines, the initiation of systemic steroids (intravenous and/or oral) had the highest concordance rate of 80% and 83%, pre- and postintervention respectively. Appropriate steroid duration (seven to 14 days) had the lowest concordance rates at 10% and 29%, pre- and postintervention respectively.

In addition, preintervention concordance (10%) involving steroid duration was the only rate considered significantly different in the postintervention group (29%). While concordance rates were high for the use of any type of nebulized bronchodilator (96% preintervention and 80% postintervention), the Level A guidelines the authors used suggested that beta-agonist bronchodilators should be used alone prior to the initiation of ipratropium bromide. The concordance rates for this guideline were 27% preintervention and 34% postintervention.

Largely, the authors felt their intervention failed to improve concordance rates to the Level A guidelines investigated and also that their findings of variable and lower concordance rates across the board corroborated other similar studies. The major weaknesses of this study included the small sample size and the nonrandomness of the sampling.

In addition, the authors report that the particular hospital studied included junior doctors who rotated on and off service, which likely prevented the effects of the intervention from being measured on a provider level. In spite of the weaknesses in the study, the article brings to light the need for a more effective translation of evidence-based guidelines to actual practice, especially in the practice of COPD management in the hospital. Further methods of guideline implementation in the clinic setting must be elucidated to improve the care patients with COPD receive in the hospital.

 

 

Not all Troponin Elevations Are Myocardial Infarctions

Jeremais A, Gibson CM. Narrative review: alternative causes for elevated cardiac troponin levels when acute coronary syndromes are excluded. Ann Intern Med. 2005;142:786-791.

Troponins are regulatory proteins that control the calcium-mediated interaction of actin and myosin during muscle contraction. All muscle tissue contains troponins, but cardiac troponin T and I have amino acid sequences that are different from skeletal and smooth muscle troponins, allowing them to be detectable by monoclonal antibody-based assays.

In the event of reversible or irreversible cell damage—or possibly even from transiently increased cell membrane permeability—cardiac troponins are released from myocytes into circulation. This characteristic provides a sensitive test for detecting myocardial injury and damage; however, this test is not specific for acute coronary syndromes. And any disorder that causes myocyte damage may cause an elevated troponin.

The 2002 American College of Cardiology/American Heart Association practice guidelines for unstable angina and non-ST-segment elevation myocardial infarction acknowledge that the myocardial necrosis signified by troponin elevation may not necessarily be caused by atherosclerotic coronary artery disease. Such nonthrombotic troponin elevation can be caused by four basic mechanisms, as discussed by Dr. Jeremias and Dr. Gibson.

  1. Demand ischemia refers to a mismatch between myocardial oxygen demand and supply in the absence of flow-limiting epicardial stenosis. Conditions such as sepsis or septic shock and the systemic inflammatory response syndrome, hypotension or hypovolemia, tachyarrhythmias, and left ventricular hypertrophy can all cause release of cardiac troponin.
  2. Myocardial ischemia in the absence of fixed obstructive coronary disease can be caused by coronary vasospasm, acute stroke or intracranial hemorrhage, and ingestion of sympathomimetics.
  3. Direct myocardial damage can be seen in cardiac contusion, direct current cardioversion, cardiac infiltrative disorders such as amyloidosis, certain chemotherapy agents, myocarditis, pericarditis, and cardiac transplantation.
  4. Myocardial strain occurs when volume and pressure overload of the left and/or right ventricle cause excessive wall tension. Congestive heat failure, acute pulmonary embolism, and chronic pulmonary hypertension can lead to myocardial strain and troponin elevation.

Another condition that can lead to persistently elevated cardiac troponins is end-stage renal disease. This elevation may be due to small areas of clinically silent myocardial necrosis, an increased left ventricular mass, or possibly from impaired renal troponin excretion. Although troponins are believed to be cleared by the reticuloendothelial system, recent evidence shows that troponin T is fragmented into molecules that are small enough to be renally excreted.

In summary, elevated troponin can be found in many clinical settings and is associated with impaired short- and long-term survival. TH

Classic Literature

The HATEFUL Patient

Every physician has groaned internally when seeing a certain patient’s name on his list, going out of her way to avoid a particular family, or getting hopelessly engaged and increasingly enraged in a battle over a “lost” narcotic prescription. There are certain patients with whom a doctor-patient relationship feels more like a contest than a partnership. These interactions make a physician’s daily practice difficult, and they may wreak havoc among the staff on an inpatient ward. These patients grow ever more intolerable to their caregivers, who often harbor a wish to simply make them disappear.

In his landmark 1978 article “Taking Care of the Hateful Patient,” (NEJM, 298:883-887) James Groves, MD, discussed the characteristics of these difficult patients and the sometimes difficult emotions they generate in their caregivers. He described four different groups of patients, using an illustrative case for each, and discussed the ways in which these patients’ often maddening behavior serves to mitigate their profound dependency.

Dependent clingers are those patients whose neediness is overt, who seem to regard the physician as a sow with teats to spare. Dr. Groves suggested early, firm limit-setting with these patients to prevent the formation and later shattering of the patient’s illusion of the physician as inexhaustible.

There are certain patients with whom a doctor-patient relationship feels more like a contest than a partnership.

Dependency lies at the heart of an entitled demander’s behavior as well, but their fear of abandonment is expressed as hostility and arrogance rather than overt neediness. Affirming to the patient that you share in their quest for the good (but not perfect) medical care to which they are entitled allows patient and physician to rally around a common goal.

This strategy backfires with manipulative help-rejecters, who seem almost pleased to report to their physician each time they fail a new treatment attempt. Overtly expressing some doubt that the treatment will completely cure all the patient’s difficulties and providing regular follow up are recommended for this group. These strategies relieve the patient of the unconscious anxiety that he may be abandoned by his physician should his symptoms abate.

Self-destructive deniers make the physician feel powerless as they persist in behavior that undermines all efforts to improve their health. With these patients, viewing their behavior as a terminal illness and managing symptoms and exacerbations accordingly allows the physician to focus on caring for the patient without unrealistic expectations of cure on the one hand and judgmental indifference on the other.

After discussing each of these groups, Dr. Groves concluded the article by suggesting that perhaps the greatest challenge physicians face in caring for these difficult patients is the temptation to disown the negative feelings they engender. He wrote that this effort not only strains the doctor’s limits, but also wastes valuable clinical data unmasked by these feelings—data that could inform clinical care. For decades prior to Dr. Groves’ article, psychoanalysts had reflected on what Freud termed “countertransference,” or the physician’s internal emotional reaction to a patient.

In his article “Hate in the Counter-Transference,” D.W. Winnicott, MD, suggested that rather than accepting the guilt that these feelings typically engender in a caregiver, negative countertransference reactions should be regarded by the physician as valuable information in understanding the patient’s psychic world. By training and by disposition, however, most physicians considered (and continue to consider) these emotions inappropriate. They seemingly negate the sympathy, kindness, and commitment to the patient’s well-being that should be central to a physician’s vocation. Conventional wisdom held that denying the feelings was the only proper response, and if that proved impossible, transferring the patient to a willing colleague was usually recommended. In contrast, Dr. Groves freed the physician to use these feelings to improve patient care.

Now a classic and oft-cited work, “Taking Care of the Hateful Patient” distills a wealth of analytic insight into a structure and language comprehensible to the busy generalist. By explaining the reactions each group of patients induces in their physicians, Dr. Groves provides useful tools to understand a particular patient’s psychology. Suggestions for strategic approaches to each category of patient are easy to understand and to adapt to one’s own practice. He explains how judicious limit-setting can be as valuable for the patient as it is for the doctor. Perhaps most helpful is his description of the needs of these patients that lie beneath their “hateful” exterior. Armed with this understanding, a physician can reclaim the empathy that is often so elusive with these patients.—Sandra Rackley MD, Kemuel Philbrick, MD

A review of staphylococcal Endocarditis

VG Fowler Jr, Miro JM, Hoen B, et al for the ICE Investigators. Staphylococcus aureus endocarditis: a consequence of medical progress. JAMA. 2005;June 22;293(24):3061-3062.

Agroup of infectious diseases experts from centers throughout the world formed the International Collaboration on Endocarditis (ICE) in 1999 to gain a global understanding of infective endocarditis. Using the Duke Criteria patients with definite infective endocarditis in a prospective manner, 275 variables were reported with these cases to a central database maintained at Duke University. The ICE-Prospective Cohort Study (ICE-PCS) enrolled 1,779 patients with infective endocarditis in 39 centers in 16 countries between June 15, 2000, and December 31, 2003, and has been described in a recent report. (Cabell CH, Abrutyn E. Infect Dis Clin North Am. 2002;16:255-72). Staphylococcus aureus was the most common cause of infective endocarditis in this group of patients (n=558; 31.6%); the authors characterized risk factors and clinical issues associated with these cases in this report.

By univariate analysis, compared with non-Staphylococcus aureus infective endocarditis, patients with infective endocarditis due to Staphylococcus aureus were more likely than patients with infective endocarditis due to other pathogens to be female (P<0.001), hemodialysis dependent (P<0.001), have diabetes mellitus (P=0.009), have other chronic illnesses (P<0.001), have a healthcare association (P<0.001), have higher rates of stroke (P<0.001), have systemic embolization (P<0.001), have persistent bacteremia (P<0.001), or die (P<0.001).

Although healthcare associated Staphylococcus aureus infective endocarditis was the most common form of Staphylococcus aureus infective endocarditis, more than 60% of healthcare-associated patients acquired the infection outside the hospital. This reflects the global trend in healthcare delivery patterns favoring ambulatory treatment (e.g., outpatient medication infusion via long-term IV access, hemodialysis)

Multivariate analysis, clinical features independently associated with Staphylococcus aureus infective endocarditis (versus non-Staphylococcus aureus infective endocarditis) were: IV drug use (OR, 9.3; 95% CI, 6.3-13.7); first clinical presentation less than one month after first symptoms (OR, 5.1; 95% CI, 3.2-8.2); healthcare-associated infection (OR, 2.9; 95% CI, 2.1-3.8), persistent bacteremia (OR, 2.3; 95% CI, 1.5-3.8), presence of a presumed intravascular device source (OR, 1.7; 95% CI, 1.2-2.6), stroke (OR, 1.6; 95% CI, 1.2-2.3), or diabetes mellitus (OR, 1.3; 95% CI, 1.1-1.8).

Patients from the United States with Staphylococcus aureus infective endocarditis were more likely to be hemodialysis-dependent, to be diabetic, to have a hemodialysis fistula or a chronic indwelling central catheter as a presumed source of infection, and to have a non-nosocomial healthcare association. Patients from the United States and Brazil were more likely to have Methicillin-resistant Staphyloccocus aureus (MRSA) than were patients from Europe, the Middle East, Australia, or New Zealand. In-hospital mortality rates were similar across regions, although American patients were significantly more likely to develop persistent bacteremia (25.6%, P<0.001).

Characteristics independently associated with mortality among patients with nonintravenous drug-use-associated Staphylococcus aureus infective endocarditis by multivariate analysis included stroke (OR, 3.67; 95% CI, 1.94-6.94), persistent bacteremia (OR, 3.06; 95% CI, 1.75-5.35), diagnosis in Southern Europe or the Middle East (OR, 3.21; 95% CI, 1.17-10.56).

This study establishes Staphylococcus aureus infective endocarditis as the leading cause of infective endocarditis in many regions of the world and spotlights the global emergence of healthcare contact as a risk factor for Staphylococcus aureus infective endocarditis. In a significant portion of these patients, an IV device was the presumed source of bacteremia; prosthetic cardiac devices (pacemakers, defibrillators, or prosthetic cardiac valves) were present in almost one-quarter of the patients.

MRSA was a significant cause of Staphylococcus aureus infective endocarditis and displayed regional variation, accounting for almost 40% of the infective endocarditis caused by Staphylococcus aureus in some regions. Patients with infective endocarditis caused by MRSA were significantly more likely to have pre-existing chronic conditions and healthcare associated infective endocarditis by both univariate and multivariate analysis. They also were often associated with persistent bacteremia. On the other hand, 20% of patients with MRSA infective endocarditis developed their infection in the absence of identifiable healthcare contact.

 

 

Limitations of this report include the fact that this is an observational study of patients from self-selected centers. Each center most likely represents a portion of the local population, making it difficult to generalize findings to the entire population centers from which this report originates. Represented hospitals were typically referral centers that have cardiac surgery programs and may have widely differing populations with varied risk factors. Advantages include the large size of this prospectively evaluated cohort and the ability to analyze regional variations between continents with a contemporary nature of the patient sample (2000-2003).

This population-based study at a medical center with detailed medical records of virtually all residents of a single county allows us to view the clinical features and etiologic factors of primarily left-sided infective endocarditis without the referral bias that tends to taint other studies typically published out of large medical centers with larger geographic referral bases.

Infectious Endocarditis in Olmsted County, Minn.

Tleyjeh IM, Steckelberg JM, Murad HS, et al. Temporal trends in infective endocarditis: a population-based study in Olmsted County, Minnesota. JAMA. 2005;293:3022-3028.

Tleyjeh and colleagues at the Mayo Clinic in Rochester, Minn., retrospectively studied 102 cases of infective endocarditis that occurred in 107 Olmsted County residents from 1970-2000. Main outcome measures were incidence of infective endocarditis, proportion of patients with underlying heart disease and causative micro-organisms and clinical characteristics. The records of all Olmsted County residents with infective endocarditis were identified and reviewed in detail. The definite and possible infective endocarditis cases as defined by modified Duke Criteria were used in the analysis.

The age- and gender-adjusted incidence of infective endocarditis ranged from 5.0 to 7.0 cases per 100,000 person-years during the study period and did not change significantly over time. There were 84 (79%) cases of native valve infective endocarditis and 23 (21%) cases of prosthetic valve infective endocarditis. Valves involved: aortic—36 (24%); mitral—49 (46%), aortic and mitral—12 (11%), right-sided or bilateral—8 (7%), or unknown—8 (7%). 16 (15%) had valve surgery within 42 days and the six-month mortality was 26% (n=28).

Infective endocarditis is a disease of the older individual in this population, with a mean age ranging from 54.1 years in 1980-1984 to 67.4 years in 1995-2000 (P=0.24 for trend). There was a male predominance (67%-83%), which did not significantly change over time.

Mitral valve prolapse was the most frequent underlying valvular heart disease. Viridans streptococci were the most common causative organisms (n=47; 44%) followed by Staphylococcus aureus (n=28 cases; 26%).

The overall average crude infective endocarditis incidence of the period 1970-2000 was 4.95 per 100,000 person-years. The age- and gender-adjusted annual incidence was 6.06 per 100,000 (95% CI, 4.89-7.22). There was no time trend for either streptococcus or Staphylococcus aureus infective endocarditis: the annual adjusted incidence of viridans group streptococcal infective endocarditis was 1.7 to 3.5 cases per 100,000 person years while Staphylococcus aureus infective endocarditis had an annual adjusted incidence of 1.0-2.2 cases per 100,000. The incidence rates of viridans group streptococcal and Staphylococcus aureus infective endocarditis have not changed significantly over time in this population.

Potential limitations of this study include possible incomplete case finding or recognition of the retrospective nature of the case reviews. The homogeneity of the patient population studied (primarily elderly white males with a low prevalence of intravenous drug use) limits the ability to generalize the results. Advantages include the fact that this is a population-based study at a medical center with detailed medical records of virtually all residents of a single county. This allows us to view the clinical features and etiologic factors of primarily left-sided infective endocarditis without the referral bias that tends to taint other studies typically published out of large medical centers with larger geographic referral bases.

 

 

The theory is that if a MET responds to see a patient who is becoming unstable, early interventions may reduce the likelihood of arrest.

Computers and Adverse Drug Events

Nebeker JR, Hoffman JM, Weir CR, Bennett CL, Hurdle JF. High rates of adverse drug events in a highly computerized hospital. Arch Intern Med. 2005;165:1111-1116.

Adverse drug events account for a significant number of hospital admissions and the ensuing costs associated with these hospitalizations. Electronic endeavors, such as computerized physician order entry (CPOE), bar code systems, and electronic medical records attempt to reduce the preventable adverse drug events.

Nebeker, et al. attempted to assess the effects of the implementation of CPOE and other computerized medication systems on adverse drug events in a tertiary care Veterans Administration Medical Center. They used an observational study design whereby 937 out of 2,306 newly admitted patients from several hospital wards were randomly chosen and assigned to a pharmacist reviewer during a 20-week period.

They reviewed complete medical records of hospital stays every other day to document adverse drug events. Not only were traditional adverse drug events identified, but harm from overdoses and/or inappropriate dose reductions or discontinuations, as well as intolerable harm from dose titration, were documented as adverse drug events. The harms caused by the drugs were considered only if the drugs were started in the hospital.

Harms were classified based on prior literature and included standards for pharmacological typology, causality assessment, error type, event terminology, drug class, seriousness index, and medication error category indexing. Additional uncommon classifications were also used, including additional resource utilization. Consensus meetings were held weekly to confirm classification of adverse drug events. Of the admissions reviewed, 483 adverse drug events were identified of which 93% were drug reactions while 7% were due to over- or underdosing. Of the drug reactions, 90% were considered dose-dependent while 10% were considered to be idiosyncratic.

Two different indexing scales were used in classifying the harms. Using the LDS Hospital Scale, it was suggested that 91% of the adverse drug events caused moderate harm while 9% caused serious harm. Using the National Coordinating Council for Medication Error Reporting and Prevention indexing, it was suggested that 87% of the adverse drug events fell into category E (requiring treatment) and 4% into category F (requiring prolonged hospitalization). Twenty-seven percent of the total adverse drug events were thought to be due to errors, including execution and planning steps. Sixty-one percent of errors occurred with the ordering mechanism while 25% of the errors occurred in the monitoring process.

This study highlighted rates of adverse drug events five to 19 times higher than baseline. The authors explained this higher-than-expected rate in part by study elements, such as the use of clinical pharmacists as reviewers, iterative case reviews, and accessible electronic data that make adverse drug events more noticeable.

Weaknesses of this study included issues of comparability of CPOEs because there were significant feature differences among commercial software programs. In addition, this was an observational study lacking a control group. The authors felt that their study did not support the idea that the computerized patient record of the study institution had caused adverse drug events. Rather, the study supported the idea that the system increased the visibility of adverse drug events compared with a paper system. In addition, the authors recommended that the choice of CPOEs be carefully considered, with a focus on decision support features when integrated into a healthcare organization.

 

 

The Questionable Benefit of Medical Emergency Teams

Hillman K, Chen J, Cretikos M, et al. Introduction of the medical emergency team (MET) system: a cluster-randomised controlled trial. MERIT study investigators. Lancet. 2005;365:2091-2097.

Previous studies have reported that the MET system reduces the incidence of cardiac arrests, deaths, and unplanned ICU admissions. A MET is a preplanned group of healthcare practitioners who respond to acute patient deteriorations in hospitalized patients.

METs are usually identical to hospital code teams, with the exception that they respond prior to a patient’s developing cardiac arrest. This early response has been shown to significantly decrease unexpected hospital mortality in hospitals in the United States, Australia, and Great Britain. Even though the system has been reported since 1995, few hospitals have knowledge of or experience with METs.

Unexpected hospital deaths and cardiac arrests are often preceded by clinical warning signs. In addition, unplanned ICU admissions may be foreshadowed by abnormalities in the patient’s vital signs that may progress if appropriate interventions are not undertaken. METs assess patients with abnormal physical findings or when there is a concern about the patient’s condition. These patients have findings that may precede a serious event or cardiac arrest, but otherwise don’t meet existing criteria to call a code.

The theory is that if a MET responds to see a patient who is becoming unstable (see “Table 1: MET Calling Criteria,” at left), early interventions may reduce the likelihood of arrest. Published studies have shown a reduction in cardiac arrests and ICU length of stay in virtually all systems in which MET has been introduced (although most studies are hampered by the use of historical controls).

The MERIT study randomized 23 hospitals in Australia to continue functioning as usual (n=11) or to introduce a MET system (n=12). The study sites included a wide range of tertiary, metropolitan, and non-metropolitan hospitals in different states across Australia. The primary outcome was the composite of cardiac arrest, unexpected death, or unplanned ICU admission during the six-month study period after MET activation, using intention to treat analysis.

A four-month educational period was undertaken with the MET centers prior to initiation of the trial. Control hospitals did not receive any education about the MET concept. This was followed by a six-month trial period. Cardiac arrest teams were maintained at all hospitals. The MET consisted of at least one doctor and a nurse from the ED or ICU.

The eligible patients included those residing on a medical ward (including critical care units); the ICUs, OR, postoperative recovery areas, and ED areas were not regarded as general wards.

The primary outcome for the study was the composite outcome of the incidence (events divided by number of eligible patients admitted to the hospital and residing on a medical ward during the study period) of:

  1. Cardiac arrests without a pre-existing “not-for-resuscitation” (NFR) order;
  2. Unplanned ICU admissions; and
  3. Unexpected deaths (those without a pre-existing NFR order).

The results of the study:

  1. During the study period, the overall rate of calls for the cardiac arrest team or MET was significantly higher in intervention hospitals than in control hospitals. Calls not associated with events were more common in MET hospitals than in controls. Half of the total calls were not associated with a cardiac arrest or unexpected death, whereas in MET hospitals more than 80% of calls were not associated with a cardiac arrest or death (P<0.0001).
  2. In patients with documented MET calling criteria in association with cardiac arrest or unexpected death, the call rate was similar in MET and control hospitals.
  3. There were no significant differences between the MET and control hospitals for any outcome.
  4. The response to changes in vital signs was not adequate—even in MET centers.
 

 

These findings are surprising in view of previously reported findings using the MET system. Potential reasons for lack of difference between MET centers and controls include:

  • Number of study sites or the duration of the study may not have been adequate for implementation or education;
  • Hospitals may already be efficient in detecting and managing unstable patients;
  • Patient selection criteria may have been overly restricted. For example, other studies have used 30 respirations per minute for tachypnea as a calling criterion compared with 36 breaths per minute used in this trial;
  • Knowledge of the study may have leaked to control hospitals;
  • Cardiac arrest teams function as METs at times: Nearly half of the calls to cardiac arrest teams in control hospitals were made without a cardiac arrest or unexpected death; and
  • The selected outcomes may not be sensitive enough.

Even though this large, multicenter controlled trial was unable to show a significant benefit of METs, we should not be discouraged from performing further controlled trials in different settings. The use of METs is clearly an exciting and evolving area of medicine.

Barriers to Patient Safety

Amalberti R, Auroy Y, Berwick D, Barach P. Five system barriers to achieving ultrasafe health care. Ann Intern Med. 2005;142:756-764

Patient safety in our healthcare system is a growing concern. One area of dialogue concerning preventable healthcare-associated harms involves the comparability of the healthcare industry with non-medical industries, such as aviation and nuclear power, that have adapted successful strategies shown to provide ultrasafe environments. Amalberti, et al. discuss risk assessment in a variety of industries and explain the need for a benchmarking approach in order to optimize or achieve safety in the healthcare field.

The authors identify five systemic barriers from literature that are fundamentally connected to the ability of the healthcare field to achieve an extremely safe environment.

Barrier 1—acceptance of limitations on maximum performance: The first barrier is the type of expected performance in the field. This is illustrated by the tradeoffs associated with ultrasafety versus productivity. The amount of risk involved was directly related to the limits placed on maximum performance. The first barrier is the acceptance that every system has limits. When a producer exceeds their limit, then safety suffers. An example used is that of blood donation: The limits of collection speed are weighed against the needed screening process.

Barrier 2—abandonment of professional autonomy: The second barrier concerns the concept of professional autonomy. While more teamwork and regulations reduce individual autonomy, this appears to improve safety in the healthcare environment. The bottom line is the importance of teamwork. The example used is that of traffic on a highway: Autonomous units work together to function safely.

Barrier 3—transition from the mindset of craftsman to that of an equivalent actor: The third barrier to achieving high levels of safety includes an equivalent actor mindset. This entails establishing a reliable standard of excellent care in lieu of focusing on individuality, similar to the notion that passengers on an airline usually do not know their pilots, but have established confidence in the airline itself.

Barrier 4—the need for system-level arbitration to optimize safety strategies: The fourth barrier identified is a need for system-level arbitration to optimize safety strategies. This need results from the pressure for justice (usually through litigation) once an accident occurs. Top-down arbitration of safety will be less successful than system level design.

Barrier 5—the need to simplify professional rules and regulations: The final barrier results from the many of layers of guidelines as they serve to create an environment of excellence. This barrier necessitates the removal of these layers to simplify the environment. Existing guidelines should be distilled down to those shown to promote quality and safety. Byzantine rules can obscure the goal of safety and glorify rules, for rules sake.

 

 

Certain structural limitations within the field, such as worker shortages in the face of increasing public demands and the reliance of the field on trainees such as students, interns, and residents, create other hurdles. The authors conclude by suggesting a two-tiered system of healthcare whereby ultrasafety could be more easily accomplished in areas of medicine considered more stable (first tier), and a second tier of care that would include the more unstable conditions, and thus inherently, represent the higher risk situations where errors are more likely to occur.

Another provocative point of this article is the need to move toward educating and training teams—not individuals.

The Importance of Implementing COPD Guidelines

Harvey PA, Murphy MC, Dornom E, et al. Implementing evidence-based guidelines: inpatient management of chronic obstructive pulmonary disease. Intern Med J. 2005;35:151-155.

COPD is a common diagnosis that sometimes requires hospitalization. Evidence-based guidelines for disease management, including that of hospitalized patients, exist, but there is a paucity of knowledge about the actual quality of care delivered in the hospital as it aligns with published guidelines. This study by Harvey, et al. explores the quality of care delivered in the hospital for patients with COPD, while at the same time investigating an intervention for the medical staff in an effort to improve adherence to evidenced-based guidelines of the disease.

Using ICD-10 codes for a COPD diagnosis, the study incorporated a retrospective chart review of 49 hospital admissions prior to the intervention and 35 admissions after the intervention in a hospital in Melbourne, Australia. Data were collected pertaining to the hospital management of COPD as it compared with what the authors considered to be Level A—or the highest level of evidence summarized from several professional organizations. The intervention delivered to the medical staff included a summarized presentation of the results from the initial audit of the 49 charts, as well as an educational package that was given to them following the presentation.

Except for inappropriate use of intravenous aminophylline, of which there was a 100% concordance to Level A guidelines, the initiation of systemic steroids (intravenous and/or oral) had the highest concordance rate of 80% and 83%, pre- and postintervention respectively. Appropriate steroid duration (seven to 14 days) had the lowest concordance rates at 10% and 29%, pre- and postintervention respectively.

In addition, preintervention concordance (10%) involving steroid duration was the only rate considered significantly different in the postintervention group (29%). While concordance rates were high for the use of any type of nebulized bronchodilator (96% preintervention and 80% postintervention), the Level A guidelines the authors used suggested that beta-agonist bronchodilators should be used alone prior to the initiation of ipratropium bromide. The concordance rates for this guideline were 27% preintervention and 34% postintervention.

Largely, the authors felt their intervention failed to improve concordance rates to the Level A guidelines investigated and also that their findings of variable and lower concordance rates across the board corroborated other similar studies. The major weaknesses of this study included the small sample size and the nonrandomness of the sampling.

In addition, the authors report that the particular hospital studied included junior doctors who rotated on and off service, which likely prevented the effects of the intervention from being measured on a provider level. In spite of the weaknesses in the study, the article brings to light the need for a more effective translation of evidence-based guidelines to actual practice, especially in the practice of COPD management in the hospital. Further methods of guideline implementation in the clinic setting must be elucidated to improve the care patients with COPD receive in the hospital.

 

 

Not all Troponin Elevations Are Myocardial Infarctions

Jeremais A, Gibson CM. Narrative review: alternative causes for elevated cardiac troponin levels when acute coronary syndromes are excluded. Ann Intern Med. 2005;142:786-791.

Troponins are regulatory proteins that control the calcium-mediated interaction of actin and myosin during muscle contraction. All muscle tissue contains troponins, but cardiac troponin T and I have amino acid sequences that are different from skeletal and smooth muscle troponins, allowing them to be detectable by monoclonal antibody-based assays.

In the event of reversible or irreversible cell damage—or possibly even from transiently increased cell membrane permeability—cardiac troponins are released from myocytes into circulation. This characteristic provides a sensitive test for detecting myocardial injury and damage; however, this test is not specific for acute coronary syndromes. And any disorder that causes myocyte damage may cause an elevated troponin.

The 2002 American College of Cardiology/American Heart Association practice guidelines for unstable angina and non-ST-segment elevation myocardial infarction acknowledge that the myocardial necrosis signified by troponin elevation may not necessarily be caused by atherosclerotic coronary artery disease. Such nonthrombotic troponin elevation can be caused by four basic mechanisms, as discussed by Dr. Jeremias and Dr. Gibson.

  1. Demand ischemia refers to a mismatch between myocardial oxygen demand and supply in the absence of flow-limiting epicardial stenosis. Conditions such as sepsis or septic shock and the systemic inflammatory response syndrome, hypotension or hypovolemia, tachyarrhythmias, and left ventricular hypertrophy can all cause release of cardiac troponin.
  2. Myocardial ischemia in the absence of fixed obstructive coronary disease can be caused by coronary vasospasm, acute stroke or intracranial hemorrhage, and ingestion of sympathomimetics.
  3. Direct myocardial damage can be seen in cardiac contusion, direct current cardioversion, cardiac infiltrative disorders such as amyloidosis, certain chemotherapy agents, myocarditis, pericarditis, and cardiac transplantation.
  4. Myocardial strain occurs when volume and pressure overload of the left and/or right ventricle cause excessive wall tension. Congestive heat failure, acute pulmonary embolism, and chronic pulmonary hypertension can lead to myocardial strain and troponin elevation.

Another condition that can lead to persistently elevated cardiac troponins is end-stage renal disease. This elevation may be due to small areas of clinically silent myocardial necrosis, an increased left ventricular mass, or possibly from impaired renal troponin excretion. Although troponins are believed to be cleared by the reticuloendothelial system, recent evidence shows that troponin T is fragmented into molecules that are small enough to be renally excreted.

In summary, elevated troponin can be found in many clinical settings and is associated with impaired short- and long-term survival. TH

Classic Literature

The HATEFUL Patient

Every physician has groaned internally when seeing a certain patient’s name on his list, going out of her way to avoid a particular family, or getting hopelessly engaged and increasingly enraged in a battle over a “lost” narcotic prescription. There are certain patients with whom a doctor-patient relationship feels more like a contest than a partnership. These interactions make a physician’s daily practice difficult, and they may wreak havoc among the staff on an inpatient ward. These patients grow ever more intolerable to their caregivers, who often harbor a wish to simply make them disappear.

In his landmark 1978 article “Taking Care of the Hateful Patient,” (NEJM, 298:883-887) James Groves, MD, discussed the characteristics of these difficult patients and the sometimes difficult emotions they generate in their caregivers. He described four different groups of patients, using an illustrative case for each, and discussed the ways in which these patients’ often maddening behavior serves to mitigate their profound dependency.

Dependent clingers are those patients whose neediness is overt, who seem to regard the physician as a sow with teats to spare. Dr. Groves suggested early, firm limit-setting with these patients to prevent the formation and later shattering of the patient’s illusion of the physician as inexhaustible.

There are certain patients with whom a doctor-patient relationship feels more like a contest than a partnership.

Dependency lies at the heart of an entitled demander’s behavior as well, but their fear of abandonment is expressed as hostility and arrogance rather than overt neediness. Affirming to the patient that you share in their quest for the good (but not perfect) medical care to which they are entitled allows patient and physician to rally around a common goal.

This strategy backfires with manipulative help-rejecters, who seem almost pleased to report to their physician each time they fail a new treatment attempt. Overtly expressing some doubt that the treatment will completely cure all the patient’s difficulties and providing regular follow up are recommended for this group. These strategies relieve the patient of the unconscious anxiety that he may be abandoned by his physician should his symptoms abate.

Self-destructive deniers make the physician feel powerless as they persist in behavior that undermines all efforts to improve their health. With these patients, viewing their behavior as a terminal illness and managing symptoms and exacerbations accordingly allows the physician to focus on caring for the patient without unrealistic expectations of cure on the one hand and judgmental indifference on the other.

After discussing each of these groups, Dr. Groves concluded the article by suggesting that perhaps the greatest challenge physicians face in caring for these difficult patients is the temptation to disown the negative feelings they engender. He wrote that this effort not only strains the doctor’s limits, but also wastes valuable clinical data unmasked by these feelings—data that could inform clinical care. For decades prior to Dr. Groves’ article, psychoanalysts had reflected on what Freud termed “countertransference,” or the physician’s internal emotional reaction to a patient.

In his article “Hate in the Counter-Transference,” D.W. Winnicott, MD, suggested that rather than accepting the guilt that these feelings typically engender in a caregiver, negative countertransference reactions should be regarded by the physician as valuable information in understanding the patient’s psychic world. By training and by disposition, however, most physicians considered (and continue to consider) these emotions inappropriate. They seemingly negate the sympathy, kindness, and commitment to the patient’s well-being that should be central to a physician’s vocation. Conventional wisdom held that denying the feelings was the only proper response, and if that proved impossible, transferring the patient to a willing colleague was usually recommended. In contrast, Dr. Groves freed the physician to use these feelings to improve patient care.

Now a classic and oft-cited work, “Taking Care of the Hateful Patient” distills a wealth of analytic insight into a structure and language comprehensible to the busy generalist. By explaining the reactions each group of patients induces in their physicians, Dr. Groves provides useful tools to understand a particular patient’s psychology. Suggestions for strategic approaches to each category of patient are easy to understand and to adapt to one’s own practice. He explains how judicious limit-setting can be as valuable for the patient as it is for the doctor. Perhaps most helpful is his description of the needs of these patients that lie beneath their “hateful” exterior. Armed with this understanding, a physician can reclaim the empathy that is often so elusive with these patients.—Sandra Rackley MD, Kemuel Philbrick, MD

A review of staphylococcal Endocarditis

VG Fowler Jr, Miro JM, Hoen B, et al for the ICE Investigators. Staphylococcus aureus endocarditis: a consequence of medical progress. JAMA. 2005;June 22;293(24):3061-3062.

Agroup of infectious diseases experts from centers throughout the world formed the International Collaboration on Endocarditis (ICE) in 1999 to gain a global understanding of infective endocarditis. Using the Duke Criteria patients with definite infective endocarditis in a prospective manner, 275 variables were reported with these cases to a central database maintained at Duke University. The ICE-Prospective Cohort Study (ICE-PCS) enrolled 1,779 patients with infective endocarditis in 39 centers in 16 countries between June 15, 2000, and December 31, 2003, and has been described in a recent report. (Cabell CH, Abrutyn E. Infect Dis Clin North Am. 2002;16:255-72). Staphylococcus aureus was the most common cause of infective endocarditis in this group of patients (n=558; 31.6%); the authors characterized risk factors and clinical issues associated with these cases in this report.

By univariate analysis, compared with non-Staphylococcus aureus infective endocarditis, patients with infective endocarditis due to Staphylococcus aureus were more likely than patients with infective endocarditis due to other pathogens to be female (P<0.001), hemodialysis dependent (P<0.001), have diabetes mellitus (P=0.009), have other chronic illnesses (P<0.001), have a healthcare association (P<0.001), have higher rates of stroke (P<0.001), have systemic embolization (P<0.001), have persistent bacteremia (P<0.001), or die (P<0.001).

Although healthcare associated Staphylococcus aureus infective endocarditis was the most common form of Staphylococcus aureus infective endocarditis, more than 60% of healthcare-associated patients acquired the infection outside the hospital. This reflects the global trend in healthcare delivery patterns favoring ambulatory treatment (e.g., outpatient medication infusion via long-term IV access, hemodialysis)

Multivariate analysis, clinical features independently associated with Staphylococcus aureus infective endocarditis (versus non-Staphylococcus aureus infective endocarditis) were: IV drug use (OR, 9.3; 95% CI, 6.3-13.7); first clinical presentation less than one month after first symptoms (OR, 5.1; 95% CI, 3.2-8.2); healthcare-associated infection (OR, 2.9; 95% CI, 2.1-3.8), persistent bacteremia (OR, 2.3; 95% CI, 1.5-3.8), presence of a presumed intravascular device source (OR, 1.7; 95% CI, 1.2-2.6), stroke (OR, 1.6; 95% CI, 1.2-2.3), or diabetes mellitus (OR, 1.3; 95% CI, 1.1-1.8).

Patients from the United States with Staphylococcus aureus infective endocarditis were more likely to be hemodialysis-dependent, to be diabetic, to have a hemodialysis fistula or a chronic indwelling central catheter as a presumed source of infection, and to have a non-nosocomial healthcare association. Patients from the United States and Brazil were more likely to have Methicillin-resistant Staphyloccocus aureus (MRSA) than were patients from Europe, the Middle East, Australia, or New Zealand. In-hospital mortality rates were similar across regions, although American patients were significantly more likely to develop persistent bacteremia (25.6%, P<0.001).

Characteristics independently associated with mortality among patients with nonintravenous drug-use-associated Staphylococcus aureus infective endocarditis by multivariate analysis included stroke (OR, 3.67; 95% CI, 1.94-6.94), persistent bacteremia (OR, 3.06; 95% CI, 1.75-5.35), diagnosis in Southern Europe or the Middle East (OR, 3.21; 95% CI, 1.17-10.56).

This study establishes Staphylococcus aureus infective endocarditis as the leading cause of infective endocarditis in many regions of the world and spotlights the global emergence of healthcare contact as a risk factor for Staphylococcus aureus infective endocarditis. In a significant portion of these patients, an IV device was the presumed source of bacteremia; prosthetic cardiac devices (pacemakers, defibrillators, or prosthetic cardiac valves) were present in almost one-quarter of the patients.

MRSA was a significant cause of Staphylococcus aureus infective endocarditis and displayed regional variation, accounting for almost 40% of the infective endocarditis caused by Staphylococcus aureus in some regions. Patients with infective endocarditis caused by MRSA were significantly more likely to have pre-existing chronic conditions and healthcare associated infective endocarditis by both univariate and multivariate analysis. They also were often associated with persistent bacteremia. On the other hand, 20% of patients with MRSA infective endocarditis developed their infection in the absence of identifiable healthcare contact.

 

 

Limitations of this report include the fact that this is an observational study of patients from self-selected centers. Each center most likely represents a portion of the local population, making it difficult to generalize findings to the entire population centers from which this report originates. Represented hospitals were typically referral centers that have cardiac surgery programs and may have widely differing populations with varied risk factors. Advantages include the large size of this prospectively evaluated cohort and the ability to analyze regional variations between continents with a contemporary nature of the patient sample (2000-2003).

This population-based study at a medical center with detailed medical records of virtually all residents of a single county allows us to view the clinical features and etiologic factors of primarily left-sided infective endocarditis without the referral bias that tends to taint other studies typically published out of large medical centers with larger geographic referral bases.

Infectious Endocarditis in Olmsted County, Minn.

Tleyjeh IM, Steckelberg JM, Murad HS, et al. Temporal trends in infective endocarditis: a population-based study in Olmsted County, Minnesota. JAMA. 2005;293:3022-3028.

Tleyjeh and colleagues at the Mayo Clinic in Rochester, Minn., retrospectively studied 102 cases of infective endocarditis that occurred in 107 Olmsted County residents from 1970-2000. Main outcome measures were incidence of infective endocarditis, proportion of patients with underlying heart disease and causative micro-organisms and clinical characteristics. The records of all Olmsted County residents with infective endocarditis were identified and reviewed in detail. The definite and possible infective endocarditis cases as defined by modified Duke Criteria were used in the analysis.

The age- and gender-adjusted incidence of infective endocarditis ranged from 5.0 to 7.0 cases per 100,000 person-years during the study period and did not change significantly over time. There were 84 (79%) cases of native valve infective endocarditis and 23 (21%) cases of prosthetic valve infective endocarditis. Valves involved: aortic—36 (24%); mitral—49 (46%), aortic and mitral—12 (11%), right-sided or bilateral—8 (7%), or unknown—8 (7%). 16 (15%) had valve surgery within 42 days and the six-month mortality was 26% (n=28).

Infective endocarditis is a disease of the older individual in this population, with a mean age ranging from 54.1 years in 1980-1984 to 67.4 years in 1995-2000 (P=0.24 for trend). There was a male predominance (67%-83%), which did not significantly change over time.

Mitral valve prolapse was the most frequent underlying valvular heart disease. Viridans streptococci were the most common causative organisms (n=47; 44%) followed by Staphylococcus aureus (n=28 cases; 26%).

The overall average crude infective endocarditis incidence of the period 1970-2000 was 4.95 per 100,000 person-years. The age- and gender-adjusted annual incidence was 6.06 per 100,000 (95% CI, 4.89-7.22). There was no time trend for either streptococcus or Staphylococcus aureus infective endocarditis: the annual adjusted incidence of viridans group streptococcal infective endocarditis was 1.7 to 3.5 cases per 100,000 person years while Staphylococcus aureus infective endocarditis had an annual adjusted incidence of 1.0-2.2 cases per 100,000. The incidence rates of viridans group streptococcal and Staphylococcus aureus infective endocarditis have not changed significantly over time in this population.

Potential limitations of this study include possible incomplete case finding or recognition of the retrospective nature of the case reviews. The homogeneity of the patient population studied (primarily elderly white males with a low prevalence of intravenous drug use) limits the ability to generalize the results. Advantages include the fact that this is a population-based study at a medical center with detailed medical records of virtually all residents of a single county. This allows us to view the clinical features and etiologic factors of primarily left-sided infective endocarditis without the referral bias that tends to taint other studies typically published out of large medical centers with larger geographic referral bases.

 

 

The theory is that if a MET responds to see a patient who is becoming unstable, early interventions may reduce the likelihood of arrest.

Computers and Adverse Drug Events

Nebeker JR, Hoffman JM, Weir CR, Bennett CL, Hurdle JF. High rates of adverse drug events in a highly computerized hospital. Arch Intern Med. 2005;165:1111-1116.

Adverse drug events account for a significant number of hospital admissions and the ensuing costs associated with these hospitalizations. Electronic endeavors, such as computerized physician order entry (CPOE), bar code systems, and electronic medical records attempt to reduce the preventable adverse drug events.

Nebeker, et al. attempted to assess the effects of the implementation of CPOE and other computerized medication systems on adverse drug events in a tertiary care Veterans Administration Medical Center. They used an observational study design whereby 937 out of 2,306 newly admitted patients from several hospital wards were randomly chosen and assigned to a pharmacist reviewer during a 20-week period.

They reviewed complete medical records of hospital stays every other day to document adverse drug events. Not only were traditional adverse drug events identified, but harm from overdoses and/or inappropriate dose reductions or discontinuations, as well as intolerable harm from dose titration, were documented as adverse drug events. The harms caused by the drugs were considered only if the drugs were started in the hospital.

Harms were classified based on prior literature and included standards for pharmacological typology, causality assessment, error type, event terminology, drug class, seriousness index, and medication error category indexing. Additional uncommon classifications were also used, including additional resource utilization. Consensus meetings were held weekly to confirm classification of adverse drug events. Of the admissions reviewed, 483 adverse drug events were identified of which 93% were drug reactions while 7% were due to over- or underdosing. Of the drug reactions, 90% were considered dose-dependent while 10% were considered to be idiosyncratic.

Two different indexing scales were used in classifying the harms. Using the LDS Hospital Scale, it was suggested that 91% of the adverse drug events caused moderate harm while 9% caused serious harm. Using the National Coordinating Council for Medication Error Reporting and Prevention indexing, it was suggested that 87% of the adverse drug events fell into category E (requiring treatment) and 4% into category F (requiring prolonged hospitalization). Twenty-seven percent of the total adverse drug events were thought to be due to errors, including execution and planning steps. Sixty-one percent of errors occurred with the ordering mechanism while 25% of the errors occurred in the monitoring process.

This study highlighted rates of adverse drug events five to 19 times higher than baseline. The authors explained this higher-than-expected rate in part by study elements, such as the use of clinical pharmacists as reviewers, iterative case reviews, and accessible electronic data that make adverse drug events more noticeable.

Weaknesses of this study included issues of comparability of CPOEs because there were significant feature differences among commercial software programs. In addition, this was an observational study lacking a control group. The authors felt that their study did not support the idea that the computerized patient record of the study institution had caused adverse drug events. Rather, the study supported the idea that the system increased the visibility of adverse drug events compared with a paper system. In addition, the authors recommended that the choice of CPOEs be carefully considered, with a focus on decision support features when integrated into a healthcare organization.

 

 

The Questionable Benefit of Medical Emergency Teams

Hillman K, Chen J, Cretikos M, et al. Introduction of the medical emergency team (MET) system: a cluster-randomised controlled trial. MERIT study investigators. Lancet. 2005;365:2091-2097.

Previous studies have reported that the MET system reduces the incidence of cardiac arrests, deaths, and unplanned ICU admissions. A MET is a preplanned group of healthcare practitioners who respond to acute patient deteriorations in hospitalized patients.

METs are usually identical to hospital code teams, with the exception that they respond prior to a patient’s developing cardiac arrest. This early response has been shown to significantly decrease unexpected hospital mortality in hospitals in the United States, Australia, and Great Britain. Even though the system has been reported since 1995, few hospitals have knowledge of or experience with METs.

Unexpected hospital deaths and cardiac arrests are often preceded by clinical warning signs. In addition, unplanned ICU admissions may be foreshadowed by abnormalities in the patient’s vital signs that may progress if appropriate interventions are not undertaken. METs assess patients with abnormal physical findings or when there is a concern about the patient’s condition. These patients have findings that may precede a serious event or cardiac arrest, but otherwise don’t meet existing criteria to call a code.

The theory is that if a MET responds to see a patient who is becoming unstable (see “Table 1: MET Calling Criteria,” at left), early interventions may reduce the likelihood of arrest. Published studies have shown a reduction in cardiac arrests and ICU length of stay in virtually all systems in which MET has been introduced (although most studies are hampered by the use of historical controls).

The MERIT study randomized 23 hospitals in Australia to continue functioning as usual (n=11) or to introduce a MET system (n=12). The study sites included a wide range of tertiary, metropolitan, and non-metropolitan hospitals in different states across Australia. The primary outcome was the composite of cardiac arrest, unexpected death, or unplanned ICU admission during the six-month study period after MET activation, using intention to treat analysis.

A four-month educational period was undertaken with the MET centers prior to initiation of the trial. Control hospitals did not receive any education about the MET concept. This was followed by a six-month trial period. Cardiac arrest teams were maintained at all hospitals. The MET consisted of at least one doctor and a nurse from the ED or ICU.

The eligible patients included those residing on a medical ward (including critical care units); the ICUs, OR, postoperative recovery areas, and ED areas were not regarded as general wards.

The primary outcome for the study was the composite outcome of the incidence (events divided by number of eligible patients admitted to the hospital and residing on a medical ward during the study period) of:

  1. Cardiac arrests without a pre-existing “not-for-resuscitation” (NFR) order;
  2. Unplanned ICU admissions; and
  3. Unexpected deaths (those without a pre-existing NFR order).

The results of the study:

  1. During the study period, the overall rate of calls for the cardiac arrest team or MET was significantly higher in intervention hospitals than in control hospitals. Calls not associated with events were more common in MET hospitals than in controls. Half of the total calls were not associated with a cardiac arrest or unexpected death, whereas in MET hospitals more than 80% of calls were not associated with a cardiac arrest or death (P<0.0001).
  2. In patients with documented MET calling criteria in association with cardiac arrest or unexpected death, the call rate was similar in MET and control hospitals.
  3. There were no significant differences between the MET and control hospitals for any outcome.
  4. The response to changes in vital signs was not adequate—even in MET centers.
 

 

These findings are surprising in view of previously reported findings using the MET system. Potential reasons for lack of difference between MET centers and controls include:

  • Number of study sites or the duration of the study may not have been adequate for implementation or education;
  • Hospitals may already be efficient in detecting and managing unstable patients;
  • Patient selection criteria may have been overly restricted. For example, other studies have used 30 respirations per minute for tachypnea as a calling criterion compared with 36 breaths per minute used in this trial;
  • Knowledge of the study may have leaked to control hospitals;
  • Cardiac arrest teams function as METs at times: Nearly half of the calls to cardiac arrest teams in control hospitals were made without a cardiac arrest or unexpected death; and
  • The selected outcomes may not be sensitive enough.

Even though this large, multicenter controlled trial was unable to show a significant benefit of METs, we should not be discouraged from performing further controlled trials in different settings. The use of METs is clearly an exciting and evolving area of medicine.

Barriers to Patient Safety

Amalberti R, Auroy Y, Berwick D, Barach P. Five system barriers to achieving ultrasafe health care. Ann Intern Med. 2005;142:756-764

Patient safety in our healthcare system is a growing concern. One area of dialogue concerning preventable healthcare-associated harms involves the comparability of the healthcare industry with non-medical industries, such as aviation and nuclear power, that have adapted successful strategies shown to provide ultrasafe environments. Amalberti, et al. discuss risk assessment in a variety of industries and explain the need for a benchmarking approach in order to optimize or achieve safety in the healthcare field.

The authors identify five systemic barriers from literature that are fundamentally connected to the ability of the healthcare field to achieve an extremely safe environment.

Barrier 1—acceptance of limitations on maximum performance: The first barrier is the type of expected performance in the field. This is illustrated by the tradeoffs associated with ultrasafety versus productivity. The amount of risk involved was directly related to the limits placed on maximum performance. The first barrier is the acceptance that every system has limits. When a producer exceeds their limit, then safety suffers. An example used is that of blood donation: The limits of collection speed are weighed against the needed screening process.

Barrier 2—abandonment of professional autonomy: The second barrier concerns the concept of professional autonomy. While more teamwork and regulations reduce individual autonomy, this appears to improve safety in the healthcare environment. The bottom line is the importance of teamwork. The example used is that of traffic on a highway: Autonomous units work together to function safely.

Barrier 3—transition from the mindset of craftsman to that of an equivalent actor: The third barrier to achieving high levels of safety includes an equivalent actor mindset. This entails establishing a reliable standard of excellent care in lieu of focusing on individuality, similar to the notion that passengers on an airline usually do not know their pilots, but have established confidence in the airline itself.

Barrier 4—the need for system-level arbitration to optimize safety strategies: The fourth barrier identified is a need for system-level arbitration to optimize safety strategies. This need results from the pressure for justice (usually through litigation) once an accident occurs. Top-down arbitration of safety will be less successful than system level design.

Barrier 5—the need to simplify professional rules and regulations: The final barrier results from the many of layers of guidelines as they serve to create an environment of excellence. This barrier necessitates the removal of these layers to simplify the environment. Existing guidelines should be distilled down to those shown to promote quality and safety. Byzantine rules can obscure the goal of safety and glorify rules, for rules sake.

 

 

Certain structural limitations within the field, such as worker shortages in the face of increasing public demands and the reliance of the field on trainees such as students, interns, and residents, create other hurdles. The authors conclude by suggesting a two-tiered system of healthcare whereby ultrasafety could be more easily accomplished in areas of medicine considered more stable (first tier), and a second tier of care that would include the more unstable conditions, and thus inherently, represent the higher risk situations where errors are more likely to occur.

Another provocative point of this article is the need to move toward educating and training teams—not individuals.

The Importance of Implementing COPD Guidelines

Harvey PA, Murphy MC, Dornom E, et al. Implementing evidence-based guidelines: inpatient management of chronic obstructive pulmonary disease. Intern Med J. 2005;35:151-155.

COPD is a common diagnosis that sometimes requires hospitalization. Evidence-based guidelines for disease management, including that of hospitalized patients, exist, but there is a paucity of knowledge about the actual quality of care delivered in the hospital as it aligns with published guidelines. This study by Harvey, et al. explores the quality of care delivered in the hospital for patients with COPD, while at the same time investigating an intervention for the medical staff in an effort to improve adherence to evidenced-based guidelines of the disease.

Using ICD-10 codes for a COPD diagnosis, the study incorporated a retrospective chart review of 49 hospital admissions prior to the intervention and 35 admissions after the intervention in a hospital in Melbourne, Australia. Data were collected pertaining to the hospital management of COPD as it compared with what the authors considered to be Level A—or the highest level of evidence summarized from several professional organizations. The intervention delivered to the medical staff included a summarized presentation of the results from the initial audit of the 49 charts, as well as an educational package that was given to them following the presentation.

Except for inappropriate use of intravenous aminophylline, of which there was a 100% concordance to Level A guidelines, the initiation of systemic steroids (intravenous and/or oral) had the highest concordance rate of 80% and 83%, pre- and postintervention respectively. Appropriate steroid duration (seven to 14 days) had the lowest concordance rates at 10% and 29%, pre- and postintervention respectively.

In addition, preintervention concordance (10%) involving steroid duration was the only rate considered significantly different in the postintervention group (29%). While concordance rates were high for the use of any type of nebulized bronchodilator (96% preintervention and 80% postintervention), the Level A guidelines the authors used suggested that beta-agonist bronchodilators should be used alone prior to the initiation of ipratropium bromide. The concordance rates for this guideline were 27% preintervention and 34% postintervention.

Largely, the authors felt their intervention failed to improve concordance rates to the Level A guidelines investigated and also that their findings of variable and lower concordance rates across the board corroborated other similar studies. The major weaknesses of this study included the small sample size and the nonrandomness of the sampling.

In addition, the authors report that the particular hospital studied included junior doctors who rotated on and off service, which likely prevented the effects of the intervention from being measured on a provider level. In spite of the weaknesses in the study, the article brings to light the need for a more effective translation of evidence-based guidelines to actual practice, especially in the practice of COPD management in the hospital. Further methods of guideline implementation in the clinic setting must be elucidated to improve the care patients with COPD receive in the hospital.

 

 

Not all Troponin Elevations Are Myocardial Infarctions

Jeremais A, Gibson CM. Narrative review: alternative causes for elevated cardiac troponin levels when acute coronary syndromes are excluded. Ann Intern Med. 2005;142:786-791.

Troponins are regulatory proteins that control the calcium-mediated interaction of actin and myosin during muscle contraction. All muscle tissue contains troponins, but cardiac troponin T and I have amino acid sequences that are different from skeletal and smooth muscle troponins, allowing them to be detectable by monoclonal antibody-based assays.

In the event of reversible or irreversible cell damage—or possibly even from transiently increased cell membrane permeability—cardiac troponins are released from myocytes into circulation. This characteristic provides a sensitive test for detecting myocardial injury and damage; however, this test is not specific for acute coronary syndromes. And any disorder that causes myocyte damage may cause an elevated troponin.

The 2002 American College of Cardiology/American Heart Association practice guidelines for unstable angina and non-ST-segment elevation myocardial infarction acknowledge that the myocardial necrosis signified by troponin elevation may not necessarily be caused by atherosclerotic coronary artery disease. Such nonthrombotic troponin elevation can be caused by four basic mechanisms, as discussed by Dr. Jeremias and Dr. Gibson.

  1. Demand ischemia refers to a mismatch between myocardial oxygen demand and supply in the absence of flow-limiting epicardial stenosis. Conditions such as sepsis or septic shock and the systemic inflammatory response syndrome, hypotension or hypovolemia, tachyarrhythmias, and left ventricular hypertrophy can all cause release of cardiac troponin.
  2. Myocardial ischemia in the absence of fixed obstructive coronary disease can be caused by coronary vasospasm, acute stroke or intracranial hemorrhage, and ingestion of sympathomimetics.
  3. Direct myocardial damage can be seen in cardiac contusion, direct current cardioversion, cardiac infiltrative disorders such as amyloidosis, certain chemotherapy agents, myocarditis, pericarditis, and cardiac transplantation.
  4. Myocardial strain occurs when volume and pressure overload of the left and/or right ventricle cause excessive wall tension. Congestive heat failure, acute pulmonary embolism, and chronic pulmonary hypertension can lead to myocardial strain and troponin elevation.

Another condition that can lead to persistently elevated cardiac troponins is end-stage renal disease. This elevation may be due to small areas of clinically silent myocardial necrosis, an increased left ventricular mass, or possibly from impaired renal troponin excretion. Although troponins are believed to be cleared by the reticuloendothelial system, recent evidence shows that troponin T is fragmented into molecules that are small enough to be renally excreted.

In summary, elevated troponin can be found in many clinical settings and is associated with impaired short- and long-term survival. TH

Classic Literature

The HATEFUL Patient

Every physician has groaned internally when seeing a certain patient’s name on his list, going out of her way to avoid a particular family, or getting hopelessly engaged and increasingly enraged in a battle over a “lost” narcotic prescription. There are certain patients with whom a doctor-patient relationship feels more like a contest than a partnership. These interactions make a physician’s daily practice difficult, and they may wreak havoc among the staff on an inpatient ward. These patients grow ever more intolerable to their caregivers, who often harbor a wish to simply make them disappear.

In his landmark 1978 article “Taking Care of the Hateful Patient,” (NEJM, 298:883-887) James Groves, MD, discussed the characteristics of these difficult patients and the sometimes difficult emotions they generate in their caregivers. He described four different groups of patients, using an illustrative case for each, and discussed the ways in which these patients’ often maddening behavior serves to mitigate their profound dependency.

Dependent clingers are those patients whose neediness is overt, who seem to regard the physician as a sow with teats to spare. Dr. Groves suggested early, firm limit-setting with these patients to prevent the formation and later shattering of the patient’s illusion of the physician as inexhaustible.

There are certain patients with whom a doctor-patient relationship feels more like a contest than a partnership.

Dependency lies at the heart of an entitled demander’s behavior as well, but their fear of abandonment is expressed as hostility and arrogance rather than overt neediness. Affirming to the patient that you share in their quest for the good (but not perfect) medical care to which they are entitled allows patient and physician to rally around a common goal.

This strategy backfires with manipulative help-rejecters, who seem almost pleased to report to their physician each time they fail a new treatment attempt. Overtly expressing some doubt that the treatment will completely cure all the patient’s difficulties and providing regular follow up are recommended for this group. These strategies relieve the patient of the unconscious anxiety that he may be abandoned by his physician should his symptoms abate.

Self-destructive deniers make the physician feel powerless as they persist in behavior that undermines all efforts to improve their health. With these patients, viewing their behavior as a terminal illness and managing symptoms and exacerbations accordingly allows the physician to focus on caring for the patient without unrealistic expectations of cure on the one hand and judgmental indifference on the other.

After discussing each of these groups, Dr. Groves concluded the article by suggesting that perhaps the greatest challenge physicians face in caring for these difficult patients is the temptation to disown the negative feelings they engender. He wrote that this effort not only strains the doctor’s limits, but also wastes valuable clinical data unmasked by these feelings—data that could inform clinical care. For decades prior to Dr. Groves’ article, psychoanalysts had reflected on what Freud termed “countertransference,” or the physician’s internal emotional reaction to a patient.

In his article “Hate in the Counter-Transference,” D.W. Winnicott, MD, suggested that rather than accepting the guilt that these feelings typically engender in a caregiver, negative countertransference reactions should be regarded by the physician as valuable information in understanding the patient’s psychic world. By training and by disposition, however, most physicians considered (and continue to consider) these emotions inappropriate. They seemingly negate the sympathy, kindness, and commitment to the patient’s well-being that should be central to a physician’s vocation. Conventional wisdom held that denying the feelings was the only proper response, and if that proved impossible, transferring the patient to a willing colleague was usually recommended. In contrast, Dr. Groves freed the physician to use these feelings to improve patient care.

Now a classic and oft-cited work, “Taking Care of the Hateful Patient” distills a wealth of analytic insight into a structure and language comprehensible to the busy generalist. By explaining the reactions each group of patients induces in their physicians, Dr. Groves provides useful tools to understand a particular patient’s psychology. Suggestions for strategic approaches to each category of patient are easy to understand and to adapt to one’s own practice. He explains how judicious limit-setting can be as valuable for the patient as it is for the doctor. Perhaps most helpful is his description of the needs of these patients that lie beneath their “hateful” exterior. Armed with this understanding, a physician can reclaim the empathy that is often so elusive with these patients.—Sandra Rackley MD, Kemuel Philbrick, MD

The Case of the Nonhealing Wound

An 85-year-old female developed a sore on the left foot (see image above) during the past six months. Throughout that time she underwent periodic debridement and local wound care with gentamicin ointment followed by the use of silver sulfadiazine cream dressings, an Unna Boot, and a surgical shoe with heel relief. Despite treatment her wound increased in size, bleeds easily, but it is not painful.

WHAT IS YOUR DIAGNOSIS?

  1. Pyogenic granuloma;
  2. Squamous cell carcinoma;
  3. Amelanotic melanoma;
  4. erkel cell carcinoma; or
  5. Hypertrophic granulation tissue?

Discussion

Amelanotic melanoma

The correct answer is C: amelanotic melanoma. The patient’s skin biopsy revealed a nodular malignant melanoma with ulceration, Clark’s level V, Breslow thickness at least 5.8 mm. She underwent wide local excision with sentinel lymph node biopsy, which was negative for tumor. The defect was repaired with a split-thickness skin graft and temporary wound vacuum. She is being closely monitored for local recurrence and in-transit metastasis.

Melanoma classically presents as an asymmetric, irregularly hyperpigmented lesion with ill-defined borders; however, some melanomas have little to no pigment and can be easily confused with other benign or malignant entities. Amelanotic melanomas comprise about 2% to 8% of all melanomas.1-2 A seemingly amelanotic lesion may have an area of subtle pigmentation peripherally that can be a clue to the diagnosis.2-3 The prognosis of amelanotic melanomas is the same as that of pigmented melanomas and is contingent upon depth of invasion, location, and patient age and gender. Unfortunately, the diagnosis of an amelanotic melanoma is often delayed, leading to more advanced tumors. Treatment is analogous to pigmented melanomas.2

A rapidly proliferating amelanotic melanoma can be clinically confused with a pyogenic granuloma, a benign vascular hyperplasia. Pyogenic granulomas present as solitary, discrete, erythematous papules or pedunculated growths on cutaneous and mucosal surfaces. They are often friable and may ulcerate. Pyogenic granulomas are more common in children and young adults, but they can occur at any age. If a pyogenic granuloma is not surgically excised, its growth will eventually stabilize, leading to involution, necrosis, or shrinkage to a fibrotic papule.4

Hypertrophic granulation tissue is another benign entity that can resemble an amelanotic melanoma. The production of granulation tissue is a normal response in the early proliferative stage of wound healing. Granulation tissue has abundant vascular structures, which give it an erythematous, edematous, and friable appearance. As wound healing progresses, granulation tissue is replaced with new epidermis through re-epithelialization.5 Failure of a wound to show signs of progressive healing should prompt a biopsy to distinguish normal granulation tissue from malignancy. Amelanotic melanoma has been reported in cases of nonhealing diabetic foot ulcers.6

Amelanotic melanoma can also be difficult to clinically distinguish from other malignant growths, such as squamous cell carcinoma. More common in elderly patients, squamous cell carcinoma commonly presents as a pink to erythematous, scaly papule, or plaque on a sun-exposed surface. Treatment of superficial squamous cell carcinoma, such as Bowen’s disease, with cryotherapy or cautery is highly effective; however, if an amelanotic melanoma is mistakenly treated as Bowen’s disease, then the delay in eventual histological diagnosis may result in an advanced stage amelanotic melanoma.7

Merkel cell carcinoma is a highly aggressive tumor that typically presents as an erythematous to violaceous, painless, solitary nodule or plaque that grows rapidly. It usually affects older patients and commonly occurs on the head. It has a high likelihood of local recurrence, metastasis, and poor prognosis.8 Merkel cell carcinomas are rare, and they elicit the same differential diagnoses as amelanotic melanomas. Histological differentiation from amelanotic melanoma is necessary. TH

Amelanotic melanoma can also be difficult to clinically distinguish from other malignant growths, such as squamous cell carcinoma. More common in elderly patients, squamous cell carcinoma commonly presents as a pink to erythematous, scaly papule, or plaque on a sun-exposed surface. Treatment of superficial squamous cell carcinoma, such as Bowen’s disease, with cryotherapy or cautery is highly effective; however, if an amelanotic melanoma is mistakenly treated as Bowen’s disease, then the delay in eventual histological diagnosis may result in an advanced stage amelanotic melanoma.7

Merkel cell carcinoma is a highly aggressive tumor that typically presents as an erythematous to violaceous, painless, solitary nodule or plaque that grows rapidly. It usually affects older patients and commonly occurs on the head. It has a high likelihood of local recurrence, metastasis, and poor prognosis.8 Merkel cell carcinomas are rare, and they elicit the same differential diagnoses as amelanotic melanomas. Histological differentiation from amelanotic melanoma is necessary. TH

An 85-year-old female developed a sore on the left foot (see image above) during the past six months. Throughout that time she underwent periodic debridement and local wound care with gentamicin ointment followed by the use of silver sulfadiazine cream dressings, an Unna Boot, and a surgical shoe with heel relief. Despite treatment her wound increased in size, bleeds easily, but it is not painful.

WHAT IS YOUR DIAGNOSIS?

  1. Pyogenic granuloma;
  2. Squamous cell carcinoma;
  3. Amelanotic melanoma;
  4. erkel cell carcinoma; or
  5. Hypertrophic granulation tissue?

Discussion

Amelanotic melanoma

The correct answer is C: amelanotic melanoma. The patient’s skin biopsy revealed a nodular malignant melanoma with ulceration, Clark’s level V, Breslow thickness at least 5.8 mm. She underwent wide local excision with sentinel lymph node biopsy, which was negative for tumor. The defect was repaired with a split-thickness skin graft and temporary wound vacuum. She is being closely monitored for local recurrence and in-transit metastasis.

Melanoma classically presents as an asymmetric, irregularly hyperpigmented lesion with ill-defined borders; however, some melanomas have little to no pigment and can be easily confused with other benign or malignant entities. Amelanotic melanomas comprise about 2% to 8% of all melanomas.1-2 A seemingly amelanotic lesion may have an area of subtle pigmentation peripherally that can be a clue to the diagnosis.2-3 The prognosis of amelanotic melanomas is the same as that of pigmented melanomas and is contingent upon depth of invasion, location, and patient age and gender. Unfortunately, the diagnosis of an amelanotic melanoma is often delayed, leading to more advanced tumors. Treatment is analogous to pigmented melanomas.2

A rapidly proliferating amelanotic melanoma can be clinically confused with a pyogenic granuloma, a benign vascular hyperplasia. Pyogenic granulomas present as solitary, discrete, erythematous papules or pedunculated growths on cutaneous and mucosal surfaces. They are often friable and may ulcerate. Pyogenic granulomas are more common in children and young adults, but they can occur at any age. If a pyogenic granuloma is not surgically excised, its growth will eventually stabilize, leading to involution, necrosis, or shrinkage to a fibrotic papule.4

Hypertrophic granulation tissue is another benign entity that can resemble an amelanotic melanoma. The production of granulation tissue is a normal response in the early proliferative stage of wound healing. Granulation tissue has abundant vascular structures, which give it an erythematous, edematous, and friable appearance. As wound healing progresses, granulation tissue is replaced with new epidermis through re-epithelialization.5 Failure of a wound to show signs of progressive healing should prompt a biopsy to distinguish normal granulation tissue from malignancy. Amelanotic melanoma has been reported in cases of nonhealing diabetic foot ulcers.6

Amelanotic melanoma can also be difficult to clinically distinguish from other malignant growths, such as squamous cell carcinoma. More common in elderly patients, squamous cell carcinoma commonly presents as a pink to erythematous, scaly papule, or plaque on a sun-exposed surface. Treatment of superficial squamous cell carcinoma, such as Bowen’s disease, with cryotherapy or cautery is highly effective; however, if an amelanotic melanoma is mistakenly treated as Bowen’s disease, then the delay in eventual histological diagnosis may result in an advanced stage amelanotic melanoma.7

Merkel cell carcinoma is a highly aggressive tumor that typically presents as an erythematous to violaceous, painless, solitary nodule or plaque that grows rapidly. It usually affects older patients and commonly occurs on the head. It has a high likelihood of local recurrence, metastasis, and poor prognosis.8 Merkel cell carcinomas are rare, and they elicit the same differential diagnoses as amelanotic melanomas.

The publication of the Competencies is the first of many steps to standardize and establish a core curriculum for hospital medicine.

Core Competencies Are Coming!

Hospital medicine core competencies to be published in January 2006

The Society of Hospital Medicine Core Competencies project continues to move toward publication in early 2006. The goals of the project are to define hospital medicine and provide a framework for the development of hospital medicine curricula throughout the continuum of professional education and training.

 

 

The Core Competencies Task Force is chaired by Mike Pistoria, DO, with key input from Dan Dressler, MD, MSc, Sylvia McKean, MD, Alpesh Amin, MD, MBA, and staffed by Tina Budnitz, MPH.

The Core Competencies Task Force developed the methods for the project and overall template for the resulting document. The template divided topic areas into three sections: Clinical, Systems Organization, and Improvement and Procedures. Topics were selected based on the frequency with which they are seen by hospitalists and the areas in which hospitalists lend a particular expertise. The Systems Organization and Improvement section is a perfect example of the latter topics. This section consists of chapters dealing with the nonclinical issues in which a practicing hospitalist should be a proficient expert. Contributors—mostly from within SHM—were recruited to write the chapters.

Once the original chapters were received, an extensive editing process began. This process ensured consistency within and across chapters. In the initial planning process, the task force decided to utilize the Knowledge, Skills, and Attitudes (KSA) domains within each chapter. Additionally, a Systems Organization and Improvement domain was added to each chapter to reflect hospitalist efforts to promote systemwide improvements in care.

As will be detailed when the Competencies are published, the KSA domains follow established definitions in the educational literature and not those commonly used in medical literature. Competencies within each domain were carefully crafted to reflect a specific level of proficiency. In other words, for each competency, it is obvious to the reader exactly what a hospitalist should be able to do and how proficiency would be evaluated.

Another part of the editing process focused on revising each chapter to stand on its own. Given the desire that the Competencies be used for curriculum development and continuing medical education, the members of the task force felt strongly that each chapter should be self-contained so an individual could pull a chapter on Community-Acquired Pneumonia, for example, and have the relevant competencies at his or her disposal.

When the first draft of the document was completed, it was sent out for review by SHM leadership and professional medical organizations. Reviewers from the Association of American Medical Colleges, the Society of General Internal Medicine, the Society of Critical Care Medicine, and the American College of Physicians provided feedback on the Competencies. Comments from other organizations invited to participate are still pending.

The Competencies will be published as a supplement to the forthcoming Journal of Hospital Medicine (JHM) in early 2006. Several related articles are also being prepared to submit to the Journal’s review process. One article will fully detail the Competencies development, while the other will be a primer on using the Competencies. The task force and the JHM editorial staff have discussed the possibility of an ongoing series within the Journal that will highlight examples of the Competencies translated into curricula and program improvements or provide an evidence-based content outline to accompany chapters. SHM is developing several Web-based resources to provide content and training tools that support the Core Competencies.

It is important to realize the publication of the Competencies is the first of many steps to standardize and establish a core curriculum for hospital medicine. The task force recognizes the Core Competencies as a fluid document. Chapters will be added over time and specific competencies within chapters may change as medicine changes and hospitalists’ roles continue to evolve.

Over the next year, the SHM Core Curriculum Task Force will be focused on evaluating the effects of the core competencies, promoting their use, and encouraging the development of curricula based on the framework provided by the competencies. If you are interested in participating in these activities please forward your nomination to participate in the Core Curriculum Task Force to Lillian Higgins at [email protected].

 

 

COMMITTEE REPORT

How to Build a Sustainable Career in Hospital Medicine

An interim report from the SHM Career Satisfaction Task Force

By Sylvia McKean, MD, Tosha Wetterneck, MD, and Win Whitcomb, MD

In 2005 SHM recognized the importance of establishing work standards for hospitalists by charging a task force to articulate key work conditions that promote success and wellness for a career in hospital medicine. As a professional society SHM is committed to developing resources for hospitalists that facilitate long and satisfying careers in hospital medicine in diverse work settings.

Since the first SHM survey of hospitalists in 1999, the role of the hospitalist has evolved to address the needs of multiple stakeholders. Reports of stress and dissatisfaction have subsequently generated dialogue on the SHM list serve. In March a recent SHM member commented: “These messages obviously concern me, and I hope the individuals can find a reasonable solution. However, I was wondering: Are management problems like these the exception or the rule?”

As a new specialty, ill-defined and evolving job descriptions can promote burnout along with other factors. Traditional residency programs in internal medicine and pediatrics don’t adequately train physicians to become hospitalists. Lack of clarity about the hospitalist role may create a mismatch between expectations of hospital leaders and junior physicians who have not yet assumed leadership roles. Hospitalists at academic medical centers are faced with additional burdens brought on by Accreditation Council for Graduate Medical Education resident workload restrictions. The absence of career promotion tracks in medical schools may limit advancement and recognition. These issues are not unique to hospital medicine and have surfaced as problems for critical care and emergency medicine.

According to the 1999 survey, burnout in general is correlated with a lower level of perceived autonomy to perform work as one sees fit and to control the professional experience.1 Less recognition by patients, families, and other professionals for a job well done and poor integration with nonphysician team members is associated with burnout. Lacking occupational solidarity as part of a team of professionals, sharing the joys and frustrations with peers, negatively affects job satisfaction.

Although the 1999 SHM study found that burnout was not independently correlated with workload, clearly there is a ceiling beyond which physicians should not work. Consistent with what the literature says about emergency medicine, professions with high demands are more likely to experience burnout. The American College of Emergency Physicians has its own wellness section that includes consensus statements about specific work parameters.

SHM has raised awareness that the hospitalist model cannot be equivalent to office practice. It’s not feasible for hospitalists to work a volume of annual hours equivalent to those worked by primary care physicians and medical specialists How Hospitalists Add Value (a special supplement to The Hospitalist published in April 2005) reinforces the need to structure reimbursement accordingly. At the SHM 2005 Annual Meeting, Tosha Wetterneck, MD, a member of the SHM Career Satisfaction Task Force and an expert on physician burnout, led a workshop on “Burnout and Hospitalists” with Michael Williams.

It’s not feasible for hospitalists to work a volume of annual hours equivalent to those worked by primary care physicians and medical specialists.

Progress Report to Date

The work of the task force intersects activities of other SHM committees and task forces. Practice support, education, leadership, benchmarks, and research are fundamental to providing hospitalists with the necessary skill set to succeed. Modifiable factors in the practice (or work environment) of local hospitals will be identified in the near future to optimally support hospitalists. In addition, the SHM 2005 Education Summit identified ongoing education as critical for the development of skills required for academic and administrative advancement.

 

 

The task force is focusing on job engagement rather than burnout—its antithesis. A profile of engagement is expected to include a sustainable workload, empowered decision-making, appropriate recognition and compensation, a supportive work environment, a sense of fairness, and meaningful and valued responsibilities appropriate to level of experience.2 Learning opportunities are highly correlated with engagement. Promising approaches to career satisfaction focus on organizational changes that enhance the capacity of hospitalists to cope with the demands of caring for hospitalized patients.

Review of data specific to hospital medicine support the need to define a sustainable workload. Findings on burnout and satisfaction from an Agency for Healthcare Research and Quality-Funded Multicenter Trial of Academic Hospitalists (David Meltzer, MD, PhD, is the principle investigator) at six medical centers provide new information, but may not be applicable to other hospitalist programs. Additional research is needed to identify the key ingredients for a long and professionally rewarding career in hospital medicine and to examine the link between clinician burnout and patient safety in diverse hospital settings.

SHM in the Big Apple

This summer the SHM logo was displayed on a billboard in Rockefeller Center in New York City. The billboard promoted DVT awareness.

Short-Term Next Steps—By Jan. 2006

One of the major goals of the Career Satisfaction Task Force is to establish national benchmarks for sustainable work conditions for hospitalists so they are engaged in a career of hospital medicine. The task force identified the following workplace domains:

  • Control/autonomy;
  • Workload/schedule;
  • Community/environment; and
  • Reward/recognition.

The task force will:

  1. Articulate predictors of job satisfaction and engagement in terms of the key domains of work life;
  2. Define and prioritize educational outreach programs to assist in the development of Core Competencies; and
  3. Develop a tool kit for building engagement and identifying modifiable factors in the workplace.

Building on the work of other SHM committees, the task force will make specific recommendations about education and practice management support to promote high productivity and career satisfaction despite high workload. Value-added information will be incorporated into the recommendations to promote adequate and fair compensation. The tool kit would be an “ideal model” that SHM would support with an explanation of how to bridge the gap between existing practice and a new flexible work structure that would meet the individual needs of hospitalists. Future revisions of the tool kit would be based on research findings.

Long -Term Next Steps: Two-Year Concurrent Time Line

Dr. Wetterneck will lead an effort to survey the SHM membership about work-life, satisfaction, and burnout to further define key aspects of hospital medicine programs and work life that maximize physician career satisfaction. Information from interviews, focus groups, and prior hospitalist surveys will guide the development of a Hospitalist Worklife and Satisfaction Survey that will be administered to the SHM membership in 2006. The SHM Board has approved funding for this initiative.

The task force will:

  • Promote future research into career satisfaction and engagement in hospital medicine to understand the magnitude of the problem of career satisfaction;
  • Specify how to structure hospital medicine programs based on actionable data;
  • Recommend how SHM can participate in improving the hospital setting as a patient care environment that not only facilitates improved patient outcomes, but also clinician workplace satisfaction for hospitalists;
  • Draft a consensus statement for the peer reviewed SHM Journal of Hospital Medicine similar to the Task Force Report on Continuous Personal, Professional and Practice Development in Family Medicine;3 and
  • Hold a workshop at the 2006 SHM Annual Meeting on Career Satisfaction.

HOW TO USE THE VTE RESOURCE ROOM

Numbered boxes correspond to suggested steps in diagram.

Step 1: From the “Improve” section, download and print the QI Workbook: VTE. Put it into a three-ring binder and allow it to support the all-important documentation of your improvement effort. First-timers may wish to view the QI Project Outline and review key concepts from the 60-slide QI Theory presentation.

Step 2: From the “Lead With” section, use any content that meets your needs, from raising institutional awareness, to bolstering your familiarity with the best evidence, to learning from the experience of others who have gone before you. Not only can you download tools and improvement stories shared by other hospitalists, you can post questions interactively for SHM’s panel of VTE and QI experts.

Step 3: From the “Educate” section, download the VTE slide presentation created for you by content expert, Sylvia McKean, MD. Use it to lecture students, residents, or other hospital staff, or to enhance your bedside teaching of VTE. You can also read pearls submitted by SHM members. Above all, as you gain your own experience with QI share it with the VTE Resource Room by e-mailing: [email protected].

WHAT’S ONLINE AT THE SHM WEB SITE

Improve Inpatient Outcomes with New SHM Online Resource

SHM Web site launches Quality Improvement Resource Rooms

In August SHM announced the first in a new online series to help hospitalists improve inpatient outcomes: the SHM Quality Improvement Resource Rooms. Although performance improvement is ultimately a local phenomenon, certain knowledge, approaches, methods, and tools transcend institution and disease.

When it comes to leading quality improvement in the hospital there has never been a pack-and-go road map—until now. With the launch of the SHM Resource Rooms, a hospitalist with nothing more than the motivation to lead measurable performance improvement in the hospital can do just that. The first Resource Room—focused on reducing venous thromboembolism (VTE), the leading cause of preventable hospital deaths—features a downloadable workbook and companion project outline that walks the hospitalist through every step in the improvement process (see details in “How to Use the VTE Resource Room,” below).

Hospitalists who extract the most out of the VTE Resource Room will be able to:

  1. Understand and use fundamental quality improvement concepts in the hospital;
  2. Command and teach the VTE prevention literature; and
  3. Engineer and lead improvement in the hospital.

The Quality Improvement Resource Rooms will support the hospitalist across domains integral to any quality improvement effort: raising collective awareness of a performance gap, knowing what evidence to put into practice, and leveraging experience with the disease as well as the improvement process.

Print and carry a ready-made workbook to guide and document your work. View a presentation depicting the key elements in quality improvement theory. Download a ready-made slide set to propel teaching of VTE prevention in the didactic setting. Adapt practical teaching tips to implement immediately. Review a listing of the pertinent literature. View and modify VTE tools shared by other hospitalists. Or post questions to a moderated forum of VTE and quality improvement experts.

 

 

By offering the new online Resource Rooms, the SHM has taken a significant step toward realizing the potential in hospital medicine: to enhance your ability to improve inpatient outcomes. The next step is yours.

At the SHM Web site, navigate to “Quality and Safety,” select “Quality Improvement Resource Rooms,” and then “Venous Thromboembolism (VTE) Resource Room.” TH

The publication of the Competencies is the first of many steps to standardize and establish a core curriculum for hospital medicine.

Core Competencies Are Coming!

Hospital medicine core competencies to be published in January 2006

The Society of Hospital Medicine Core Competencies project continues to move toward publication in early 2006. The goals of the project are to define hospital medicine and provide a framework for the development of hospital medicine curricula throughout the continuum of professional education and training.

 

 

The Core Competencies Task Force is chaired by Mike Pistoria, DO, with key input from Dan Dressler, MD, MSc, Sylvia McKean, MD, Alpesh Amin, MD, MBA, and staffed by Tina Budnitz, MPH.

The Core Competencies Task Force developed the methods for the project and overall template for the resulting document. The template divided topic areas into three sections: Clinical, Systems Organization, and Improvement and Procedures. Topics were selected based on the frequency with which they are seen by hospitalists and the areas in which hospitalists lend a particular expertise. The Systems Organization and Improvement section is a perfect example of the latter topics. This section consists of chapters dealing with the nonclinical issues in which a practicing hospitalist should be a proficient expert. Contributors—mostly from within SHM—were recruited to write the chapters.

Once the original chapters were received, an extensive editing process began. This process ensured consistency within and across chapters. In the initial planning process, the task force decided to utilize the Knowledge, Skills, and Attitudes (KSA) domains within each chapter. Additionally, a Systems Organization and Improvement domain was added to each chapter to reflect hospitalist efforts to promote systemwide improvements in care.

As will be detailed when the Competencies are published, the KSA domains follow established definitions in the educational literature and not those commonly used in medical literature. Competencies within each domain were carefully crafted to reflect a specific level of proficiency. In other words, for each competency, it is obvious to the reader exactly what a hospitalist should be able to do and how proficiency would be evaluated.

Another part of the editing process focused on revising each chapter to stand on its own. Given the desire that the Competencies be used for curriculum development and continuing medical education, the members of the task force felt strongly that each chapter should be self-contained so an individual could pull a chapter on Community-Acquired Pneumonia, for example, and have the relevant competencies at his or her disposal.

When the first draft of the document was completed, it was sent out for review by SHM leadership and professional medical organizations. Reviewers from the Association of American Medical Colleges, the Society of General Internal Medicine, the Society of Critical Care Medicine, and the American College of Physicians provided feedback on the Competencies. Comments from other organizations invited to participate are still pending.

The Competencies will be published as a supplement to the forthcoming Journal of Hospital Medicine (JHM) in early 2006. Several related articles are also being prepared to submit to the Journal’s review process. One article will fully detail the Competencies development, while the other will be a primer on using the Competencies. The task force and the JHM editorial staff have discussed the possibility of an ongoing series within the Journal that will highlight examples of the Competencies translated into curricula and program improvements or provide an evidence-based content outline to accompany chapters. SHM is developing several Web-based resources to provide content and training tools that support the Core Competencies.

It is important to realize the publication of the Competencies is the first of many steps to standardize and establish a core curriculum for hospital medicine. The task force recognizes the Core Competencies as a fluid document. Chapters will be added over time and specific competencies within chapters may change as medicine changes and hospitalists’ roles continue to evolve.

Over the next year, the SHM Core Curriculum Task Force will be focused on evaluating the effects of the core competencies, promoting their use, and encouraging the development of curricula based on the framework provided by the competencies. If you are interested in participating in these activities please forward your nomination to participate in the Core Curriculum Task Force to Lillian Higgins at [email protected].

 

 

COMMITTEE REPORT

How to Build a Sustainable Career in Hospital Medicine

An interim report from the SHM Career Satisfaction Task Force

By Sylvia McKean, MD, Tosha Wetterneck, MD, and Win Whitcomb, MD

In 2005 SHM recognized the importance of establishing work standards for hospitalists by charging a task force to articulate key work conditions that promote success and wellness for a career in hospital medicine. As a professional society SHM is committed to developing resources for hospitalists that facilitate long and satisfying careers in hospital medicine in diverse work settings.

Since the first SHM survey of hospitalists in 1999, the role of the hospitalist has evolved to address the needs of multiple stakeholders. Reports of stress and dissatisfaction have subsequently generated dialogue on the SHM list serve. In March a recent SHM member commented: “These messages obviously concern me, and I hope the individuals can find a reasonable solution. However, I was wondering: Are management problems like these the exception or the rule?”

As a new specialty, ill-defined and evolving job descriptions can promote burnout along with other factors. Traditional residency programs in internal medicine and pediatrics don’t adequately train physicians to become hospitalists. Lack of clarity about the hospitalist role may create a mismatch between expectations of hospital leaders and junior physicians who have not yet assumed leadership roles. Hospitalists at academic medical centers are faced with additional burdens brought on by Accreditation Council for Graduate Medical Education resident workload restrictions. The absence of career promotion tracks in medical schools may limit advancement and recognition. These issues are not unique to hospital medicine and have surfaced as problems for critical care and emergency medicine.

According to the 1999 survey, burnout in general is correlated with a lower level of perceived autonomy to perform work as one sees fit and to control the professional experience.1 Less recognition by patients, families, and other professionals for a job well done and poor integration with nonphysician team members is associated with burnout. Lacking occupational solidarity as part of a team of professionals, sharing the joys and frustrations with peers, negatively affects job satisfaction.

Although the 1999 SHM study found that burnout was not independently correlated with workload, clearly there is a ceiling beyond which physicians should not work. Consistent with what the literature says about emergency medicine, professions with high demands are more likely to experience burnout. The American College of Emergency Physicians has its own wellness section that includes consensus statements about specific work parameters.

SHM has raised awareness that the hospitalist model cannot be equivalent to office practice. It’s not feasible for hospitalists to work a volume of annual hours equivalent to those worked by primary care physicians and medical specialists How Hospitalists Add Value (a special supplement to The Hospitalist published in April 2005) reinforces the need to structure reimbursement accordingly. At the SHM 2005 Annual Meeting, Tosha Wetterneck, MD, a member of the SHM Career Satisfaction Task Force and an expert on physician burnout, led a workshop on “Burnout and Hospitalists” with Michael Williams.

It’s not feasible for hospitalists to work a volume of annual hours equivalent to those worked by primary care physicians and medical specialists.

Progress Report to Date

The work of the task force intersects activities of other SHM committees and task forces. Practice support, education, leadership, benchmarks, and research are fundamental to providing hospitalists with the necessary skill set to succeed. Modifiable factors in the practice (or work environment) of local hospitals will be identified in the near future to optimally support hospitalists. In addition, the SHM 2005 Education Summit identified ongoing education as critical for the development of skills required for academic and administrative advancement.

 

 

The task force is focusing on job engagement rather than burnout—its antithesis. A profile of engagement is expected to include a sustainable workload, empowered decision-making, appropriate recognition and compensation, a supportive work environment, a sense of fairness, and meaningful and valued responsibilities appropriate to level of experience.2 Learning opportunities are highly correlated with engagement. Promising approaches to career satisfaction focus on organizational changes that enhance the capacity of hospitalists to cope with the demands of caring for hospitalized patients.

Review of data specific to hospital medicine support the need to define a sustainable workload. Findings on burnout and satisfaction from an Agency for Healthcare Research and Quality-Funded Multicenter Trial of Academic Hospitalists (David Meltzer, MD, PhD, is the principle investigator) at six medical centers provide new information, but may not be applicable to other hospitalist programs. Additional research is needed to identify the key ingredients for a long and professionally rewarding career in hospital medicine and to examine the link between clinician burnout and patient safety in diverse hospital settings.

SHM in the Big Apple

This summer the SHM logo was displayed on a billboard in Rockefeller Center in New York City. The billboard promoted DVT awareness.

Short-Term Next Steps—By Jan. 2006

One of the major goals of the Career Satisfaction Task Force is to establish national benchmarks for sustainable work conditions for hospitalists so they are engaged in a career of hospital medicine. The task force identified the following workplace domains:

  • Control/autonomy;
  • Workload/schedule;
  • Community/environment; and
  • Reward/recognition.

The task force will:

  1. Articulate predictors of job satisfaction and engagement in terms of the key domains of work life;
  2. Define and prioritize educational outreach programs to assist in the development of Core Competencies; and
  3. Develop a tool kit for building engagement and identifying modifiable factors in the workplace.

Building on the work of other SHM committees, the task force will make specific recommendations about education and practice management support to promote high productivity and career satisfaction despite high workload. Value-added information will be incorporated into the recommendations to promote adequate and fair compensation. The tool kit would be an “ideal model” that SHM would support with an explanation of how to bridge the gap between existing practice and a new flexible work structure that would meet the individual needs of hospitalists. Future revisions of the tool kit would be based on research findings.

Long -Term Next Steps: Two-Year Concurrent Time Line

Dr. Wetterneck will lead an effort to survey the SHM membership about work-life, satisfaction, and burnout to further define key aspects of hospital medicine programs and work life that maximize physician career satisfaction. Information from interviews, focus groups, and prior hospitalist surveys will guide the development of a Hospitalist Worklife and Satisfaction Survey that will be administered to the SHM membership in 2006. The SHM Board has approved funding for this initiative.

The task force will:

  • Promote future research into career satisfaction and engagement in hospital medicine to understand the magnitude of the problem of career satisfaction;
  • Specify how to structure hospital medicine programs based on actionable data;
  • Recommend how SHM can participate in improving the hospital setting as a patient care environment that not only facilitates improved patient outcomes, but also clinician workplace satisfaction for hospitalists;
  • Draft a consensus statement for the peer reviewed SHM Journal of Hospital Medicine similar to the Task Force Report on Continuous Personal, Professional and Practice Development in Family Medicine;3 and
  • Hold a workshop at the 2006 SHM Annual Meeting on Career Satisfaction.

HOW TO USE THE VTE RESOURCE ROOM

Numbered boxes correspond to suggested steps in diagram.

Step 1: From the “Improve” section, download and print the QI Workbook: VTE. Put it into a three-ring binder and allow it to support the all-important documentation of your improvement effort. First-timers may wish to view the QI Project Outline and review key concepts from the 60-slide QI Theory presentation.

Step 2: From the “Lead With” section, use any content that meets your needs, from raising institutional awareness, to bolstering your familiarity with the best evidence, to learning from the experience of others who have gone before you. Not only can you download tools and improvement stories shared by other hospitalists, you can post questions interactively for SHM’s panel of VTE and QI experts.

Step 3: From the “Educate” section, download the VTE slide presentation created for you by content expert, Sylvia McKean, MD. Use it to lecture students, residents, or other hospital staff, or to enhance your bedside teaching of VTE. You can also read pearls submitted by SHM members. Above all, as you gain your own experience with QI share it with the VTE Resource Room by e-mailing: [email protected].

WHAT’S ONLINE AT THE SHM WEB SITE

Improve Inpatient Outcomes with New SHM Online Resource

SHM Web site launches Quality Improvement Resource Rooms

In August SHM announced the first in a new online series to help hospitalists improve inpatient outcomes: the SHM Quality Improvement Resource Rooms. Although performance improvement is ultimately a local phenomenon, certain knowledge, approaches, methods, and tools transcend institution and disease.

When it comes to leading quality improvement in the hospital there has never been a pack-and-go road map—until now. With the launch of the SHM Resource Rooms, a hospitalist with nothing more than the motivation to lead measurable performance improvement in the hospital can do just that. The first Resource Room—focused on reducing venous thromboembolism (VTE), the leading cause of preventable hospital deaths—features a downloadable workbook and companion project outline that walks the hospitalist through every step in the improvement process (see details in “How to Use the VTE Resource Room,” below).

Hospitalists who extract the most out of the VTE Resource Room will be able to:

  1. Understand and use fundamental quality improvement concepts in the hospital;
  2. Command and teach the VTE prevention literature; and
  3. Engineer and lead improvement in the hospital.

The Quality Improvement Resource Rooms will support the hospitalist across domains integral to any quality improvement effort: raising collective awareness of a performance gap, knowing what evidence to put into practice, and leveraging experience with the disease as well as the improvement process.

Print and carry a ready-made workbook to guide and document your work. View a presentation depicting the key elements in quality improvement theory. Download a ready-made slide set to propel teaching of VTE prevention in the didactic setting. Adapt practical teaching tips to implement immediately. Review a listing of the pertinent literature. View and modify VTE tools shared by other hospitalists. Or post questions to a moderated forum of VTE and quality improvement experts.

 

 

By offering the new online Resource Rooms, the SHM has taken a significant step toward realizing the potential in hospital medicine: to enhance your ability to improve inpatient outcomes. The next step is yours.

At the SHM Web site, navigate to “Quality and Safety,” select “Quality Improvement Resource Rooms,” and then “Venous Thromboembolism (VTE) Resource Room.” TH

HOW TO USE THE VTE RESOURCE ROOM

Numbered boxes correspond to suggested steps in diagram.

Step 1: From the “Improve” section, download and print the QI Workbook: VTE. Put it into a three-ring binder and allow it to support the all-important documentation of your improvement effort. First-timers may wish to view the QI Project Outline and review key concepts from the 60-slide QI Theory presentation.

Step 2: From the “Lead With” section, use any content that meets your needs, from raising institutional awareness, to bolstering your familiarity with the best evidence, to learning from the experience of others who have gone before you. Not only can you download tools and improvement stories shared by other hospitalists, you can post questions interactively for SHM’s panel of VTE and QI experts.

Step 3: From the “Educate” section, download the VTE slide presentation created for you by content expert, Sylvia McKean, MD. Use it to lecture students, residents, or other hospital staff, or to enhance your bedside teaching of VTE. You can also read pearls submitted by SHM members. Above all, as you gain your own experience with QI share it with the VTE Resource Room by e-mailing: [email protected].

WHAT’S ONLINE AT THE SHM WEB SITE

Improve Inpatient Outcomes with New SHM Online Resource

SHM Web site launches Quality Improvement Resource Rooms

In August SHM announced the first in a new online series to help hospitalists improve inpatient outcomes: the SHM Quality Improvement Resource Rooms. Although performance improvement is ultimately a local phenomenon, certain knowledge, approaches, methods, and tools transcend institution and disease.

When it comes to leading quality improvement in the hospital there has never been a pack-and-go road map—until now. With the launch of the SHM Resource Rooms, a hospitalist with nothing more than the motivation to lead measurable performance improvement in the hospital can do just that. The first Resource Room—focused on reducing venous thromboembolism (VTE), the leading cause of preventable hospital deaths—features a downloadable workbook and companion project outline that walks the hospitalist through every step in the improvement process (see details in “How to Use the VTE Resource Room,” below).

Hospitalists who extract the most out of the VTE Resource Room will be able to:

  1. Understand and use fundamental quality improvement concepts in the hospital;
  2. Command and teach the VTE prevention literature; and
  3. Engineer and lead improvement in the hospital.

The Quality Improvement Resource Rooms will support the hospitalist across domains integral to any quality improvement effort: raising collective awareness of a performance gap, knowing what evidence to put into practice, and leveraging experience with the disease as well as the improvement process.

Print and carry a ready-made workbook to guide and document your work. View a presentation depicting the key elements in quality improvement theory. Download a ready-made slide set to propel teaching of VTE prevention in the didactic setting. Adapt practical teaching tips to implement immediately. Review a listing of the pertinent literature. View and modify VTE tools shared by other hospitalists. Or post questions to a moderated forum of VTE and quality improvement experts.

 

 

By offering the new online Resource Rooms, the SHM has taken a significant step toward realizing the potential in hospital medicine: to enhance your ability to improve inpatient outcomes. The next step is yours.

At the SHM Web site, navigate to “Quality and Safety,” select “Quality Improvement Resource Rooms,” and then “Venous Thromboembolism (VTE) Resource Room.” TH

The New and the Timeless

The New and the Timeless

I recently picked up volume 1, number 1 of The Hospitalist, which was edited by John Nelson and Win Whitcomb and published in spring 1997. The Hospitalist was six pages long and had five articles and three job advertisements. The articles included one by Bob Wachter about how hospitalists represent “without a doubt … a bona fide new specialty in American medicine,” and one by Richard Slataper about how hospitalists improve quality of care.

As I compare volume 1, number 1 with the current volume, I marvel at how much things have changed—and how much they have stayed the same. The change is obvious just by looking at The Hospitalist. The similarities are evident by reading the content. We still talk about how hospital medicine is emerging as a new specialty and is taking important strides in that direction. Quality is still the key metric by which we measure our practice.

With this volume, we enter a new, exciting era for The Hospitalist with a new format, new editorial staff leadership, and a new publisher—but the same commitment to excellence and dedication to addressing key issues in the field of hospital medicine. I thank Jim Pile for his outstanding job as the previous editor of The Hospitalist. Jamie Newman assumes the role of physician editor with this issue, and I am excited to have his energy and creative ideas to lead the new phase of this important publication.

It has been said that half of what you learn in medical school is obsolete five years after you graduate. The trouble is you can’t know which half that will be until five years later. I remember being warned as an intern never to give a beta-blocker to a patient with heart failure. We now know that beta-blockers are lifesaving for people with heart failure. We are fortunate to practice in a world where scientific discoveries enhance our ability to help our patients and where the pace of discovery is growing by leaps and bounds. I wish I could list everything we do today that will be obsolete in five years, but my crystal ball is not that clear. Because I cannot predict what will change in medicine, I have instead thought about what does not change. As we celebrate the new with this volume of The Hospitalist I want to remember what is timeless in our profession.

One of my mentors says, “Don’t just do something, sit there.” When I am confused about what is going on with a patient, my best aid in figuring things out is to pull up a chair and have the patient tell me his story from the beginning.

Cornerstones of Diagnosis

With so much technology it is easy to believe that technology makes the diagnosis and heals the patient. But despite all of the new and amazing tests at our disposal, the patient history and physical examination remain the cornerstones of diagnosis.

It has been said that in more than 90% of cases the correct diagnosis appears on the differential after the history and physical. The tests merely help to confirm or rule out diagnoses. As technology races ahead the importance of sitting at the bedside, talking with the patient, and hearing her story stays constant.

One of my mentors says, “Don’t just do something, sit there.” When I’m confused about what is going on with a patient, my best aid in figuring things out is to pull up a chair and have the patient tell me his story from the beginning. What I like so much about being a hospitalist is that I have the ability to spend that kind of time when I need to. Unlike the outpatient setting where patients are scheduled every 15 minutes regardless of the reason for the visit, in the hospital I can be more flexible about how I allocate my time. I can spend time sitting and listening.

 

 

There is an apocryphal story I like that says that if you sit down in the patient’s room the patient will experience your visit as having lasted longer than if you stand for the same amount of time. I say apocryphal because I have searched for this study but have never found it; however, I believe it. Patients also like telling their story. There is healing in the telling and in knowing that you have been heard. As so much of medicine changes, sitting with the patient and hearing her story remains timeless.

Reach Out and Touch

Another part of medicine that has not changed over the millennia is the power of touch. During my second year of residency I realized that in many situations the physical examination just didn’t add much to my care of the patient. Perhaps this fact reflected my physical examination skills, but I believe it was more a function of realizing that in the absence of complaints in the chest I was unlikely to discover something on lung exam.

The great symbolism and importance of touching and examining the patient goes beyond discovering the unexpected finding. The laying on of hands creates a physical connection to the patient and can heal. I now make it a point to physically examine every patient every day. I examine patients not just to support billing and not just because there just may be a new finding, but because there is power and healing in touch. I want the patient to benefit from this power and I want to connect to it for myself. As a hospitalist I feel privileged to be able to be at the bedside with patients.

Identify with the Patient

Another timeless part of patient care is empathy. Many patients simply want someone to walk alongside them and understand their experience of illness. Empathy makes this possible.

As I talk with patients I use myself as a guide for understanding the patient’s emotional experience and try to reflect that back. More than simply taking the history or laying my hands on the patient, I try to understand what the patient is feeling and going through. The fear and loneliness of illness can be greatly relieved by knowing that another person understands your experience and is walking with you. Our patients’ need and desire for empathy has not changed despite all of our technological innovations.

As hospitalists we meet people at their sickest and most vulnerable. They enter the foreign world of the hospital where they are often alone and where they have little to no control over what happens to them. Patients typically can’t even dictate the basics of life in the hospital like when or what they can eat. Even if we imagine the ideal hospital of the future built around the patient and that affords maximum control to the patient, the hospital will still be foreign. The power of empathy and the human interaction it represents will remain as important in this ideal hospital as it is today and as it always has been.

Education Never Ends

The other certainty in medicine is that science and technology will advance, bringing new and better ways to diagnose and treat illness. Thus the final constant in medicine is the need to always be learning. As an attending I had to learn that beta-blockers were good for people with heart failure and saved lives. I have learned many more new things since residency and understand the need to continue to learn.

Another wonderful aspect of being a hospitalist is the continuous progress of medical care and the ability to apply it to help patients. Advances in diagnosis and treatment, changes to systems that ensure that all patients receive this care, and attention to patient safety, quality, and palliative care all help ensure that patients receive the best possible care. Hospitalists are at the forefront of all of these activities.

 

 

In Conclusion

I delight in the new and celebrate progress that this era for The Hospitalist represents. I’m proud of the The Hospitalist and look forward to it continuing the tradition of quality while it expands and grows in new ways. In the same way I’m excited about medical advances but try always to remember what is timeless. Sitting with patients, listening to them, touching them, and being empathic reap great rewards for patients and for us.

As hospitalists we care for people at their most vulnerable moments. At those times our humanity, our gentle, caring touch, and our empathy matter most. In addition to bringing to bear the best that modern medicine has to offer in medications, diagnostic tests, and interventions let us remember the power to heal that we bring to the bedside when we bring ourselves—open to being with the patient and not just doing something but sitting there.

Involuntary admission: Weighing patient rights vs. appropriate care

Widower denies suicidal thoughts in hospital, but acts on them at home

DuPage County (IL) Circuit Court

A 77-year-old man was hospitalized after complaining of chest pain. He reported attempting suicide the night before by taking pills. His wife had died 5 months previously.

When the psychiatrist evaluated the patient the next day, the patient assured him that he was no longer suicidal, refused inpatient admission, but agreed to enter outpatient therapy. The patient repeated this intent to the hospital social worker.

The psychiatrist arranged visits by a home health care nurse. The patient was discharged after a 2-day stay, and the nurse visited the following day. The patient assured the nurse that he was not suicidal and called the psychiatrist to make an appointment for the next week. Two days later, the patient stabbed himself to death at home.

The estate claimed the psychiatrist should have kept the patient hospitalized. The psychiatrist claimed that involuntary admission was not possible because the patient was not dangerous to himself or others. The patient’s toxicology screen was negative except for his prescription drugs.

  • The jury decided for the defense

Alcoholic promises to attend AA, but takes his life on Christmas Day

Davidson County (TN) Circuit Court

A 44-year-old man with a long history of alcohol abuse and failed rehabilitation was involuntarily admitted to a hospital after threatening suicide. His blood alcohol level was 0.393, and he had threatened suicide at the same facility 8 months before. A court order gave the hospital authority to involuntarily detain him until a hearing the following week.

The next day, the patient was transferred from the detoxification center to the psychiatric unit and evaluated by the psychiatrist. The patient disavowed suicidal thoughts, and the psychiatrist discharged the patient the following day (Christmas Eve, 48 hours after admission). The psychiatrist based this decision partially on the patient’s promise to enter inpatient alcohol treatment and attend an Alcoholics Anonymous meeting within 2 days.

On Christmas Day, the patient shot himself and died. His blood alcohol content at the time of death was 0.303.

The patient’s estate charged that the final discharge was negligent, the discharge instructions were inadequate, and the psychiatrist and hospital’s assessments were inaccurate.

The hospital argued that it deferred to the psychiatrist in the discharge decision. The psychiatrist argued that state law defined holding an individual without “immediate risk of substantial harm” as a felony.

  • The jury decided in favor of the defendant psychiatrist. A directed verdict was granted for the hospital.

Plaintiff: Discharge led to hemiplegia

Broward County (FL) Circuit Court

Police took into custody a 27-year-old woman who had been wandering a public road, apparently under the influence of illegal substances. The officers transported her to a hospital, where the emergency room staff admitted her for psychiatric evaluation.

The psychiatrist determined that involuntary admission was not appropriate. When the patient refused the psychiatrist’s recommendation for voluntary admission, she was discharged.

The patient then went to her mother’s house, began drinking, and became combative. She started brandishing a rifle. The next day, the weapon discharged and a bullet lodged in her spine at the L2 vertebra. The patient is now hemiplegic and has no bladder or bowel control. She alleged that the hospital and psychiatrist were negligent in not admitting her.

  • The hospital reached a $50,000 settlement before trial; the jury returned a $190,007 award, with 90% of fault apportioned to the plaintiff and 10% to the psychiatrist. After setoffs, the plaintiff’s net award was $80.

Dr. Grant’s observations

These cases illustrate suicide risk factors psychiatrists must consider even when a patient denies suicidal thoughts or intent. Suicide risk factors these patients showed include:

  • recent discharge from psychiatric facilities1
  • recent suicide attempt with fairly high lethality potential (overdosing on pills)
  • depressive turmoil and psychological isolation (recent loss of spouse)
  • older widowed male2-3
  • history of dangerous behavior when intoxicated4
  • possible “holiday effect.”5
These cases reflect one of psychiatry’s more troubling job requirements: assessing whether a patient is safe to discharge or should be admitted involuntarily. Such situations force us to balance the civil liberties of the mentally ill with our responsibility to care for those who lack insight into their illnesses. This tension often weighs heavily on psychiatrists6 and is, unfortunately, rather common. A study at one hospital found that approximately 8.5% of emergency department visits resulted in involuntary admission.7

As the verdicts in these cases suggest, the legal system recognizes that psychiatrists cannot predict suicide.8 Mistakes in clinical judgment are not the same as negligence, however, and failure to assess suicide risk or intervene appropriately for the level of risk may result in successful negligence claims.

 

 

Standards for emergency short-term hospitalization vary from state to state, so familiarize yourself with your state’s standards. Although one standard for involuntary admission is often imminent threat of harm to self, do not base the threat of danger only on a patient’s self-report. One study of patients who committed suicide while hospitalized found that 78% denied suicidal thoughts at their last communication.9 However, “locking up” suicidal patients to prevent a malpractice suit is equally inappropriate.

Assess suicide risk during a thoroughly documented psychiatric examination with particular attention to the patient’s history of suicidal behavior. Record details of the assessment in the patient’s chart (Table) at the time of evaluation, and document how these clinical factors influence your final decision.

Involuntary hospitalization provides the immediate benefit of supervision in a safe environment, and patients can gain short-term therapeutic benefits from inpatient treatment whether or not the admission was voluntary.10 Patients may eventually recognize admission was helpful, but their attitudes about the process often do not become more positive. To ease the stress of involuntary admission:

  • acknowledge the patient’s disapproval
  • tell the patient why he’s being hospitalized
  • inform the patient about his or her legal rights.
Carry out this discussion with respect for the patient’s dignity and wishes.

Widower denies suicidal thoughts in hospital, but acts on them at home

DuPage County (IL) Circuit Court

A 77-year-old man was hospitalized after complaining of chest pain. He reported attempting suicide the night before by taking pills. His wife had died 5 months previously.

When the psychiatrist evaluated the patient the next day, the patient assured him that he was no longer suicidal, refused inpatient admission, but agreed to enter outpatient therapy. The patient repeated this intent to the hospital social worker.

The psychiatrist arranged visits by a home health care nurse. The patient was discharged after a 2-day stay, and the nurse visited the following day. The patient assured the nurse that he was not suicidal and called the psychiatrist to make an appointment for the next week. Two days later, the patient stabbed himself to death at home.

The estate claimed the psychiatrist should have kept the patient hospitalized. The psychiatrist claimed that involuntary admission was not possible because the patient was not dangerous to himself or others. The patient’s toxicology screen was negative except for his prescription drugs.

  • The jury decided for the defense

Alcoholic promises to attend AA, but takes his life on Christmas Day

Davidson County (TN) Circuit Court

A 44-year-old man with a long history of alcohol abuse and failed rehabilitation was involuntarily admitted to a hospital after threatening suicide. His blood alcohol level was 0.393, and he had threatened suicide at the same facility 8 months before. A court order gave the hospital authority to involuntarily detain him until a hearing the following week.

The next day, the patient was transferred from the detoxification center to the psychiatric unit and evaluated by the psychiatrist. The patient disavowed suicidal thoughts, and the psychiatrist discharged the patient the following day (Christmas Eve, 48 hours after admission). The psychiatrist based this decision partially on the patient’s promise to enter inpatient alcohol treatment and attend an Alcoholics Anonymous meeting within 2 days.

On Christmas Day, the patient shot himself and died. His blood alcohol content at the time of death was 0.303.

The patient’s estate charged that the final discharge was negligent, the discharge instructions were inadequate, and the psychiatrist and hospital’s assessments were inaccurate.

The hospital argued that it deferred to the psychiatrist in the discharge decision. The psychiatrist argued that state law defined holding an individual without “immediate risk of substantial harm” as a felony.

  • The jury decided in favor of the defendant psychiatrist. A directed verdict was granted for the hospital.

Plaintiff: Discharge led to hemiplegia

Update from the Public Policy Committee

One of SHM’s missions is to advocate policies and positions that support hospital medicine, hospitalists, and our patients. SHM also engages broader issues impacting the delivery, quality, and safety of medical care and lobbies for policies that ensure public health and safety. Legislators, payers, and healthcare administrators use SHM’s policy statements to guide their understanding of and expectations for hospital medicine and its practitioners.

The Public Policy Committee (PPC) is SHM’s primary resource for researching and recommending policy and advocacy positions to the Board of Directors. We respond to issues raised by SHM members, federal and state healthcare legislation, and hospital and health plan policies that affect hospital medicine, hospitalists, and patients.

  • In 1999, SHM stood firmly against health plans mandating PCP referral to hospitalists. Our stance defused concerns about hospital medicine raised by primary care physicians and helped to fuel the rapid growth of hospital medicine.
  • In 2001, some hospitalists were having hospital privileges withheld because of their designation as hospitalists. The SHM condemned this practice and insisted that hospitalists should be subject to the same privileging and credentialing process as other physicians practicing inpatient medicine.

Recently, SHM members raised concerns over hospitals’ mandating that hospitalists maintain responsibility for patient follow-up after discharge. Based upon the PPC’s research and recommendation, the SHM Board approved a policy clarifying the role of the hospitalist in the continuum of care. (“The Hospitalist,” May/June 2005) This policy will clarify expectations for hospital medicine practices as they develop care management arrangements with hospitals, physicians, and payers.

Currently, the PPC is spearheading several initiatives:

  • We are coordinating SHM’s participation in CMS’s 5-year review of valuation of E&M codes.
  • In conjunction with a respected health policy analysis firm, we are developing a “hospital medicine White Paper,” which will serve as the definitive description of what hospital medicine is and document its potential to change health care. It will serve as our primary tool to communicate with legislators, policy makers, third-party payers, and healthcare leaders to further the mission and values of hospital medicine as a specialty.
  • Finally, the PPC is leveraging our Washington, DC, venue for the 2006 Annual Meeting to organize a “hospital medicine Legislative Day.” At this event, hospitalists will visit legislators to discuss issues of importance to hospital medicine, such as patient safety and allocation of healthcare resources. We hope that this event will further raise awareness of hospital medicine and spur hospitalists to become politically active on behalf of our specialty.

Finally, on behalf of the members of the PPC, I want to thank Mary Jo Gorman for her 2-year stewardship of the Public Policy Committee. Her drive, vision, and enthusiasm were key to many of the successes described above.

1. Chimowitz MI, Lynn MJ, Howlett-Smith H, et al. Comparison of warfarin and aspirin for symptomatic intracranial arterial stenosis. N Engl J Med. 352:1305-16.

This is the first prospective study comparing antithrombotic therapies for patients with atherosclerotic stenosis of major intracranial arteries. This multicenter, NINDS-sponsored, placebo-controlled, blinded study randomized 569 patients to aspirin (650 mg twice daily) or warfarin (initially 5 mg daily, titrated to achieve an INR of 2.0–3.0) and followed them for nearly 2 years. The study was terminated early over safely concerns about patients in the warfarin group. Baseline characteristics between the 2 groups were not significantly different. Warfarin was not more effective than aspirin in its effect on the primary endpoints of ischemic stroke, brain hemorrhage, or vascular death other than from stroke (as defined in the study protocol). However, major cardiac events (myocardial infarction or sudden death) were significantly higher in the warfarin group, and major hemorrhage (defined as any intracranial or systemic hemorrhage requiring hospitalization, transfusion, or surgical intervention) was also significantly higher in the warfarin group. The authors note the difficulty maintaining the INR in the target range (achieved only 63.1 % of the time during the maintenance period, an observation in line with other anticoagulation studies). In an accompanying editorial, Dr. Koroshetz of the stroke service at the Massachusetts General Hospital also observed that difficulties in achieving the therapeutic goal with warfarin could have impacted the results. The authors also note that the dose of aspirin employed in this study is somewhat higher than in previous trials. Nevertheless, until other data emerge, this investigation’s results favor aspirin in preference to warfarin for this high-risk condition.

Of the various types of medical errors, medication errors are believed to be the most common. At the time of hospital admission, medication discrepancies may lead to unintended drug interactions, toxicity, or interruption of appropriate drug therapies. These investigators performed a prospective study to identify unintended medication discrepancies between the patient’s home medications and those ordered at the time of the patient’s admission and to evaluate the potential clinical significance of these discrepancies.

This study was conducted at a 1,000-bed tertiary care hospital in Canada on the general medicine teaching service. A member of the study team reviewed each medical record to ascertain the physician-recorded medication history, the nurse-recorded medication history, the admission medication orders, and demographic information. A comprehensive list of all of the patient’s prescription or nonprescription drugs was compiled by interviewing patients, families, and pharmacists, and by inspecting the bottles. A discrepancy was defined as any difference between this comprehensive list and the admission medication orders. These were categorized into omission or addition of a medication, substitution of an agent within the same drug class, and change in dose, route, and frequency of administration of an agent. The medical team caring for the patient was then asked whether or not these discrepancies were intended. The team then reconciled any unintended discrepancies. These unintended discrepancies were further classified according to their potential for harm by 3 medical hospitalists into Class 1, 2, 3, in increasing order of potential harm. One hundred fifty-one patients were included in the analysis. A total of 140 errors occurred in 81 patients (54%). The overall error rate was 0.93 per patient. Of the errors, 46% consisted of omission of a regularly prescribed medication, 25% involved discrepant doses, 17.1% involved discrepant frequency, and 11.4% were actually incorrect drugs. Breakdown of error severity resulted in designation of 61% as Class 1, 33% as Class 2, and 5.7% as Class 3. The interrater agreement was a kappa of 0.26. These discrepancies were not found to be associated with night or weekend admissions, high patient volume, or high numbers of medications.

 

 

Real-time clinical correlation with the responsible physicians allowed distinction of intended from unintended discrepancies. This presumably improved the accuracy of the error rate measurement. This study confirmed the relatively high rate previously reported. Further study can focus on possible intervention to minimize these errors.

3. Liperoti R, Gambassi G, Lapane KL, et al. Conventional and atypical antipsychotics and the risk of hospitalization for ventricular arrhythmias or cardiac arrest Arch Intern Med. 2005;165:696-701.

As the number of hospitalized elderly and demented patients increases, use of both typical and atypical antipsychotics has become prevalent. QT prolongation, ventricular arrhythmia, and cardiac arrest are more commonly associated with the older conventional antipsychotics than with newer atypical agents. This case-control study was conducted to estimate the effect of both conventional and atypical antipsychotics use on the risk of hospital admission for ventricular arrhythmia or cardiac arrest.

The patient population involved consisted of elderly nursing home residents in 6 US states. The investigators utilized Systematic Assessment of Geriatric Drug Use via Epidemiology database that contains data from minimum data set (MDS), a standardized data set required of all certified nursing homes in the United States. Case patients were selected by ICD-9 codes for cardiac arrest or ventricular arrhythmia. Control patients were selected via ICD-9 codes of 6 other common inpatient diagnoses. Antipsychotic exposure was determined by use of the most recent assessment in the nursing homes prior to admission. Exposed patients were those who received atypical antipsychotics such as risperidone, olanzapine, quetiapine, and clozapine, and those who used conventional agents such as haloperidol and others. After control for potential confounders, users of conventional antipsychotics showed an 86% increase in the risk of hospitalization for ventricular arrhythmias or cardiac arrest (OR: 1.86) compared with nonusers. No increased risk was reported for users of atypical antipsychotics. (OR: 0.87). When compared with atypical antipsychotic use, conventional antipsychotic use carries an OR of 2.13 for these cardiac outcomes. In patients using conventional antipsychotics, the presence and absence of cardiac diseases were 3.27 times and 2.05 times, respectively, more likely to be associated with hospitalization for ventricular arrhythmias and cardiac arrest, compared with nonusers without cardiac diseases.

These results suggest that atypical antipsychotics may carry less cardiac risk than conventional agents. In an inpatient population with advancing age and increasing prevalence of dementia and cardiac disease, use of atypical antipsychotic agents may be safer than older, typical agents.

This placebo-controlled, double-blind, multicenter, industry-sponsored trial of early treatment of hemorrhagic stroke with rFVIIa at 3 escalating doses, evaluated stroke hematoma growth, mortality, and functional outcomes up to 90 days. The authors note the substantial mortality and high morbidity of this condition, which currently lacks definitive treatment. Patients within 3 hours of symptoms with intracerebral hemorrhage on CT and who met study criteria were randomized to receive either placebo or a single intravenous dose of 40, 80, or 160 mcg/kg of rFVIIa within 1 hour of baseline CT and no more than 4 hours after symptoms. Follow-up CTs at 24 and 72 hours were obtained and functional assessments were performed serially at frequent intervals throughout the study period. Three hundred ninety-nine patients were analyzed and were found similar in their baseline characteristics. Lesion volume was significantly less with treatment, in a dose-dependent fashion. Mortality at 3 months was significantly less (29% vs. 18%) with treatment, and all 4 of the global functional outcome scales utilized were favorable, 3 of them (modified Rankin Scale for all doses, NIH Stroke Scale for all doses, and the Barthel Index at the 80 and 160 mcg/kg doses) in a statistically significant fashion. However, the authors noted an increase in serious thromboembolic events in the treatment groups, with a statistically significant increased frequency of arterial thromboembolic events. These included myocardial ischemic events and cerebral infarction, and most occurred within 3 days of rFVIIa treatment. Of note, the majority of patients who suffered these events made recovery from their complications, and the overall rates of fatal or disabling thromboembolic occurrences between the treatment and placebo groups were similar. This study offers new and exciting insights into potential therapy for this serious form of stroke, although safety concerns merit further study.

Warfarin therapy is widely used in geriatric populations. Sometimes over-anticoagulation occurs when warfarin therapy is initiated based on standard loading and maintenance dose in the hospital setting. This is mainly due to decreased hepatic clearance and polypharmacy in the geriatric population. A recent study in France demonstrated a useful and simple low-dose regimen for starting warfarin therapy (target INR: 2.0–3.0) in the elderly without over-anticoagulation. The patients enrolled in this study were typical geriatric patients with multiple comorbid conditions. These patients also received concomitant medications known to potentiate the effect of warfarin. One hundred six consecutive inpatients (age %70, mean age of 85 years) were given a 4-mg induction dose of warfarin for 3 days, and INR levels were measured on the 4th day. From this point, the daily warfarin dose was adjusted according to an algorithm (see Table 1), and INR values were obtained every 2–3 days until actual maintenance doses were determined. The maintenance dose was defined as the amount of warfarin required to yield an INR in 2.0 to 3.0 range on 2 consecutive samples obtained 48–72 hours apart in the absence of any dosage change for at least 4 days. Based on this algorithm, the predicted daily warfarin dose (3.1 ± 1.6 mg/day) correlated closely with the actual maintenance dose (3.2 ± 1.7 mg/day). The average time needed to achieve a therapeutic INR was 6.7 ± 3.3 days. None of the patients had an INR >4.0 during the induction period. This regimen also required fewer INR measurements.

Intracranial hemorrhage and gastrointestinal bleeding are serious complications of over-anticoagulation. The majority of gastrointestinal bleeding episodes respond to withholding warfarin and reversing anticoagulation. However, intracranial hemorrhage frequently leads to devastating outcomes. A recent report suggested that an age over 85 and INR of 3.5 or greater were associated with increased risk of intracranial hemorrhage. The warfarin algorithm proposed in this study provides a simple, safe, and effective tool to predict warfarin dosing in elderly hospitalized patients without over-anticoagulation. Although this regimen still needs to be validated in a large patient population in the future, it can be incorporated into computer-based dosing entry programs in the hospital setting to guide physicians in initiating warfarin therapy.

Whether to isolate a patient for suspected pulmonary tuberculosis (TB) is often a balancing act between clinical risk assessment and optimal hospital resource utilitization. Practitioners need a relatively simple but sophisticated tool that they can use at the bedside to more precisely assess the likelihood of TB for more efficient and effective triage.

These authors previously developed such a tool with a sensitivity of 98% and specificity of 46%. (See Table 2 for details) This study was designed to validate this decision rule in a new set of patients. Patients were enrolled in 2 tertiary-care hospitals in New York City area over a 21-month period. They were all admitted and isolated because of clinical suspicion for pulmonary TB, not utilizing the decision rule under study. Study team members collected demographic, clinical risk factors, presenting symptoms, and signs, laboratory, and radiographic findings. Chest x-ray findings were reviewed by investigators who were blinded to the other clinical and demographical information. The gold standard of diagnosis was at least 1 sputum culture that was positive for Mycobacterium tuberculosis.

 

 

A total of 516 patients were enrolled in this study. Of the 516, 19 (3.7%) were found to have culture-proven pulmonary TB. Univariate analyses showed that history of positive PPD, higher (98% vs. 95%) oxygen saturation, upper-lobe consolidation (not upper lobe cavity), and lymphadenopathy (hilar, mediastinal, or paratracheal) were all associated with the presence of pulmonary TB. Shortness of breath was associated with the absence of TB. A total score of 1 or higher in the prediction rule had a sensitivity of 95% for pulmonary TB, and score of less than 1 had a specificity of 35%. The investigators estimated a prevalence of 3.7%, thereby yielding a positive predictive value of 9.6% but a negative predictive value of 99.7%. They estimated that 35% of patients isolated would not have been with this prediction rule.

Though validated scientifically, this tool still has a false-negative rate of 5%. In a less endemic area, the false-negative rate would be correspondingly lower and thus more acceptable from a public health perspective. This is one step closer to a balance of optimal bed utilization and reasoned clinical assessment.

This placebo-controlled, double-blind, multicenter, industry-sponsored trial of early treatment of hemorrhagic stroke with rFVIIa at 3 escalating doses, evaluated stroke hematoma growth, mortality, and functional outcomes up to 90 days. The authors note the substantial mortality and high morbidity of this condition, which currently lacks definitive treatment. Patients within 3 hours of symptoms with intracerebral hemorrhage on CT and who met study criteria were randomized to receive either placebo or a single intravenous dose of 40, 80, or 160 mcg/kg of rFVIIa within 1 hour of baseline CT and no more than 4 hours after symptoms. Follow-up CTs at 24 and 72 hours were obtained and functional assessments were performed serially at frequent intervals throughout the study period. Three hundred ninety-nine patients were analyzed and were found similar in their baseline characteristics. Lesion volume was significantly less with treatment, in a dose-dependent fashion. Mortality at 3 months was significantly less (29% vs. 18%) with treatment, and all 4 of the global functional outcome scales utilized were favorable, 3 of them (modified Rankin Scale for all doses, NIH Stroke Scale for all doses, and the Barthel Index at the 80 and 160 mcg/kg doses) in a statistically significant fashion. However, the authors noted an increase in serious thromboembolic events in the treatment groups, with a statistically significant increased frequency of arterial thromboembolic events. These included myocardial ischemic events and cerebral infarction, and most occurred within 3 days of rFVIIa treatment. Of note, the majority of patients who suffered these events made recovery from their complications, and the overall rates of fatal or disabling thromboembolic occurrences between the treatment and placebo groups were similar. This study offers new and exciting insights into potential therapy for this serious form of stroke, although safety concerns merit further study.

Warfarin therapy is widely used in geriatric populations. Sometimes over-anticoagulation occurs when warfarin therapy is initiated based on standard loading and maintenance dose in the hospital setting. This is mainly due to decreased hepatic clearance and polypharmacy in the geriatric population. A recent study in France demonstrated a useful and simple low-dose regimen for starting warfarin therapy (target INR: 2.0–3.0) in the elderly without over-anticoagulation. The patients enrolled in this study were typical geriatric patients with multiple comorbid conditions. These patients also received concomitant medications known to potentiate the effect of warfarin. One hundred six consecutive inpatients (age %70, mean age of 85 years) were given a 4-mg induction dose of warfarin for 3 days, and INR levels were measured on the 4th day. From this point, the daily warfarin dose was adjusted according to an algorithm (see Table 1), and INR values were obtained every 2–3 days until actual maintenance doses were determined. The maintenance dose was defined as the amount of warfarin required to yield an INR in 2.0 to 3.0 range on 2 consecutive samples obtained 48–72 hours apart in the absence of any dosage change for at least 4 days. Based on this algorithm, the predicted daily warfarin dose (3.1 ± 1.6 mg/day) correlated closely with the actual maintenance dose (3.2 ± 1.7 mg/day). The average time needed to achieve a therapeutic INR was 6.7 ± 3.3 days. None of the patients had an INR >4.0 during the induction period. This regimen also required fewer INR measurements.

Intracranial hemorrhage and gastrointestinal bleeding are serious complications of over-anticoagulation. The majority of gastrointestinal bleeding episodes respond to withholding warfarin and reversing anticoagulation. However, intracranial hemorrhage frequently leads to devastating outcomes. A recent report suggested that an age over 85 and INR of 3.5 or greater were associated with increased risk of intracranial hemorrhage. The warfarin algorithm proposed in this study provides a simple, safe, and effective tool to predict warfarin dosing in elderly hospitalized patients without over-anticoagulation. Although this regimen still needs to be validated in a large patient population in the future, it can be incorporated into computer-based dosing entry programs in the hospital setting to guide physicians in initiating warfarin therapy.

Whether to isolate a patient for suspected pulmonary tuberculosis (TB) is often a balancing act between clinical risk assessment and optimal hospital resource utilitization. Practitioners need a relatively simple but sophisticated tool that they can use at the bedside to more precisely assess the likelihood of TB for more efficient and effective triage.

These authors previously developed such a tool with a sensitivity of 98% and specificity of 46%. (See Table 2 for details) This study was designed to validate this decision rule in a new set of patients. Patients were enrolled in 2 tertiary-care hospitals in New York City area over a 21-month period. They were all admitted and isolated because of clinical suspicion for pulmonary TB, not utilizing the decision rule under study. Study team members collected demographic, clinical risk factors, presenting symptoms, and signs, laboratory, and radiographic findings. Chest x-ray findings were reviewed by investigators who were blinded to the other clinical and demographical information. The gold standard of diagnosis was at least 1 sputum culture that was positive for Mycobacterium tuberculosis.

 

 

A total of 516 patients were enrolled in this study. Of the 516, 19 (3.7%) were found to have culture-proven pulmonary TB. Univariate analyses showed that history of positive PPD, higher (98% vs. 95%) oxygen saturation, upper-lobe consolidation (not upper lobe cavity), and lymphadenopathy (hilar, mediastinal, or paratracheal) were all associated with the presence of pulmonary TB. Shortness of breath was associated with the absence of TB. A total score of 1 or higher in the prediction rule had a sensitivity of 95% for pulmonary TB, and score of less than 1 had a specificity of 35%. The investigators estimated a prevalence of 3.7%, thereby yielding a positive predictive value of 9.6% but a negative predictive value of 99.7%. They estimated that 35% of patients isolated would not have been with this prediction rule.

Though validated scientifically, this tool still has a false-negative rate of 5%. In a less endemic area, the false-negative rate would be correspondingly lower and thus more acceptable from a public health perspective. This is one step closer to a balance of optimal bed utilization and reasoned clinical assessment.

Role of Computerized Physician Order Entry Systems in Facilitating Medication Errors

Koppel R, Metlay JP, Cohen A, et al. Role of computerized physician order entry systems in facilitating medication errors. JAMA. 2005;293:1197-1203.

Computerized Physician Order Entry (CPOE) has been touted as an effective means to reduce medical errors, especially medication errors. There have been preliminary studies that showed both potential and actual error reductions with CPOE. More recent data suggested that there may be potential for facilitating errors as well.

Koppel et al. aimed to study CPOE system-related factors that may actually increase risk of medication errors. The authors conducted structured interviews with end users (housestaff, pharmacists, nurses, nurse managers, and attending physicians), real-time observations of end users interfacing with the system, entering orders, charting medications, and reviewing orders, and focus groups with housestaff. These qualitative data were used to help generate a 71-question structured survey subsequently given to the housestaff. These questions pertain to working conditions, sources of stress, and errors. There were 261 responses representing an 88% response rate.

Twenty-two previously unexplored potential medication error sources abstracted from the survey were grouped into the 2 categories: 1) information errors, and 2) human-machine interface flaws. The first category refers to fragmented data and the disparate information systems within hospitals. The latter category includes rigid machine programming that does not correspond to or facilitate workflow. Only 10 survey elements with sufficiently robust results were reported. About 40% of respondents used CPOE to determine dosage of infrequently prescribed medications at least once a week or more. Incorrect doses may be ordered if users follow the dosage information in the system that is based on drug inventory rather than clinical recommendations. Twenty-two percent of respondents noted that more than once a week duplicate or conflicting medications were ordered and not detected for several hours. Disorganized display of patient medications was believed to be partly responsible. More than 80% of respondents noted unintended delay in renewing antibiotics at least once. Such gaps were possible partially because the reminder system occurred in the paper chart while order entry was done with the computer. With respect to the human-machine interface, 55% reported difficulty identifying the correct patient because of poor or fragmented displays, and 23% reported this occurring more than a few times per week. System downtime leading to delay in order entry was reported by 47% to occur more than once a week. System inflexibility also led to difficulties in specifying medications and ordering nonformulary medications. This was reported by 31% to occur at least several times a week, and 24% reported this daily or more frequently.

This was a survey of end users of a CPOE system in a single institution, and the survey elements were mainly estimates of error risks. Nevertheless, it appropriately draws attention to the importance of the unique culture of each institution, efficient workflow, and coherent human-machine interface. The anticipated error reductions may not materialize if these issues are neglected. Hospitalists can serve a critical role in implementation and customization of CPOE systems that allow clinicians to do the right thing more timely and efficiently.

Risk Stratification for In-hospital Mortality in Acutely Decompensated Heart Failure: Classification and Regression Tree Analysis

Fonarow GC, Adams KF, Abraham WT, Yancy CW, Boscardin WJ; ADHERE Scientific Advisory Committee, Study Group, and Investigators. Risk stratification for in-hospital mortality in acutely decompensated heart failure: classification and regression tree analysis. JAMA. 2005;293:572-80.

Heart failure is an important and growing cause of hospitalization in this country, and it is one of the most common clinical entities encountered by hospitalists. While there are some risk assessment tools available for outpatients with heart failure, there has not been a risk stratification tool published for inpatients. In this study by Fonarow et al. in JAMA, the authors describe a simple risk-stratification formula for in-hospital mortality in patients with acutely decompensated heart failure. Data from the ADHERE registry (Acute Decompensated Heart Failure National Registry, which is industry sponsored, as was this study) were used to model the risk of in-hospital death using a classification and regression tree (CART) analysis. This was done in a 2-stage process. First, investigators established a derivation cohort of approximately 33,000 patients (sequential hospital admissions from October 2001 to February 2003) from the ADHERE registry, and used the CART method to analyze 39 clinical variables to determine which were the best predictors of in-hospital mortality. This analysis was used to derive a risk tree to partition patients into low-, intermediate-, and high-risk groups. Second, the validity of this method was tested by applying the prediction tool to a cohort of the subsequent 32,229 patients hospitalized in the ADHERE registry, from March 2003 to July 2003. The results were striking. Baseline characteristics and clinical outcomes between the derivation and validation cohorts were similar across the wide range of parameters examined. The difference in mortality between the low-, intermediate-, and high-risk groups was 23.6% in the highest-risk category and 1.8% in the low-risk category, while the intermediate group was stratified into 3 levels, with 20.0%, 5.0%, and 5.1% mortality risk in intermediate group levels 1, 2, and 3, respectively. Aside from the more than 10-fold range in mortality risk across the various groups, the outstanding feature of the authors’ findings was that 3 simple parameters were the most significant predictors of in-hospital mortality risk: BUN, SBP, and serum creatinine. Specifically, combinations of a serum BUN of 43 or greater, a serum creatinine of 2.75 or greater, and a systolic blood pressure of less than 115 were associated with higher mortality. They note that adding other predictors did not meaningfully increase the model’s accuracy. The authors comment that unlike other predictive models based on multivariate analyses (which are often complex, and therefore difficult to employ at bedside), this simple tool is easy to use. An additional advantage is that the data needed are typically available at time of admission and can therefore be used to make a timely clinical decision in terms of triage into an appropriate level of care. Similar risk assessment tools exist for the risk stratification of patients with the acute coronary syndrome, and given the frequency with which patients are admitted with acutely decompensated heart failure, this new tool should prove a welcome addition to the clinical decision-making abilities of hospitalists.

 

 

Risk of Endocarditis among Patients with Prosthetic Valves and Staphylococcus Aureus Bacteremia

El-Ahdab F, Benjamin DK, Wang A, , et al. Risk of endocarditis among patients with prosthetic valves and Staphylococcus aureus bacteremia. Am J Med. 2005;118:225-9.

The risk of developing endocarditis in patients with Staphylococcus aureus bacteremia and prosthetic valves increases as more than 600,000 prosthetic valves are implanted annually in the United States. A prospective study at Duke University identified 51 patients with prosthetic valves or mitral ring who developed S. aureus bacteremia. The modified Duke criteria were used for the diagnosis of endocarditis. The onset and sources of bacteremia, locations of acquiring bacteremia, as well as clinical outcome were analyzed. The overall incidence of definite prosthetic valve endocarditis was as high as 51%, with the remaining 49% patients meeting Duke criteria for possible endocarditis. The results showed that endocarditis occurred more frequently in mitral (62%) and aortic positions (48%), and with mitral ring the rate of endocarditis was slightly lower (33%). Among prostheses, mechanical and bioprosthetic valves had endocarditis rates of 62% and 44%, respectively. About 63% of patients had early onset of bacteremia (<1 year after valve placement), and 37% had late onset of bacteremia (>1 year after valve placement). Overall, the most common source of bacteremia was from infected surgical wound sites (33%). Early bacteremia was more likely to result from infected surgical wound sites (59%), while late bacteremia was more likely to have an unidentified source (48%). The majority of episodes of bacteremia (47%) were hospital-acquired (i.e., a positive blood culture occurred >72 hours after admission). The frequency of healthcare-associated bacteremia and community-acquired bacteremia was about 26%–27%.

In terms of mortality, there was no difference for a patient with early and late S. aureus bacteremia, bioprosthetic and mechanical valves, and infection due to methicillin-resistant or methicillin-susceptible S. aureus. However, mortality was higher among patients with definite endocarditis (62%) vs. possible endocarditis (28%). Patients with endocarditis who underwent valve surgery had lower mortality than those who did not undergo valve surgery due to inoperable comorbid conditions, such as stroke, multiorgan system failure, and mediastinitis. Persistent fever (≥ 38°C after 72 hours of adequate parenteral antibiotics) and persistent bacteremia (positive blood culture within 2–4 days of the initial positive blood culture) were independently associated with definite endocarditis with odds ratio of 4.4 and 11.7, respectively. Overall, 96% of patients underwent echocardiography (55% with both transesophageal and transthoracic echo, 14% with only transesophageal echo, 27% with only transthoracic echo). However, 10% patients with definite endocarditis had no diagnostic finding on either transthoracic or transesophageal echocardiography.

S. aureus bacteremia is a common phenomenon in inpatient settings. This study demonstrated an approximately 50% rate of definite prosthetic valve endocarditis in patients with S. aureus bacteremia. The risks of endocarditis were independent of valve type, location, and duration of implantation. This study highlights the need for aggressive treatment and evaluation of S. aureus bacteremia in patients with prosthetic valves. Clinically, persistent fever and bacteremia were independently associated with definite endocarditis in this study population. Clinicians cannot over-rely on transesophageal echocardiogram to identify occult endocarditis in high-risk patients.

Optimizing the Prediction of Perioperative Mortality in Vascular Surgery by Using a Customized Probability Model

Kertai MD, Boersma E, Klein J, van Urk H, Poldermans D. Optimizing the prediction of perioperative mortality in vascular surgery by using a customized probability model. Arch Intern Med. 2005;165:898-904.

Traditional perioperative risk-assessment models and indexes have focused primarily on cardiac outcomes and involved mainly clinical risk factors. The model proposed in this paper focused instead on overall mortality and incorporated not only clinical risk factors but also more precise surgery-specific risks and the use of beta-blocker and statin agents.

Investigators in the Netherlands targeted only vascular surgery patients identified from a computerized hospital information system. From a system, 2,310 patients who underwent 2,758 noncardiac vascular surgeries during a 10-year period in the 1990s were selected. Clinical risk factors, data on noninvasive stress testing, and long-term medication use, including statin agents, beta-blockers, calcium channel blockers, diuretics, insulin, nitrate, and aspirin, were abstracted. Outcome measures were all-cause mortality before discharge or within 30 days after surgery. The proposed model (see Figure) was based on modifications of the original Goldman Index, with the addition of more precise surgery risk stratification and statin and beta-blocker use. The specific types of vascular surgeries: carotid endarterectomy, infrainguinal bypass, abdominal aortic surgery, thoracoabdominal surgery, and acute abdominal aortic aneurysm rupture repair, carried systematically increased risk in expected fashion. Upon univariate analysis in the derivation cohort (n = 1,537), most of the clinical predictors from the Goldman Index were associated with increased perioperative mortality. Similar conclusions persisted in multivariate logistic regression analysis. Risk of surgical procedures, cardiovascular morbidity (ischemic heart disease, congestive heart failure, history of cerebrovascular event, and hypertension), renal dysfunction, and chronic pulmonary disease are independent predictors of increased all-cause perioperative mortality. In contrast, use of beta-blockers and statins were associated with reduced incidence of perioperative mortality. The final model included a scoring system with points assigned according to risk estimates of individual predictors. Beta-blocker and statin use in this model are assigned negative scores as their use lowers risk. For example, a patient with ischemic heart disease and hypertension undergoing abdominal aortic surgery would have a score of 46, corresponding to a 14% probability of mortality. That risk would be reduced to about 4% (score of 31) by use of beta-blockers (−15). In the same database, with 773 patients as the validation cohort, this prediction model performed nearly as well as the derivation model. Hypertension was not found to be an independent predictor in this validation cohort.

This tool appears provide robust risk assessment for vascular surgery patients. The inclusion of estimated benefit-of-statin and beta-blocker use may allow a more accurate “net” risk assessment. Those patients who are already on these 2 agents but still deemed at higher risk can be informed and may benefit from close monitoring. Additional preoperative interventions may include revascularization, if these high-risk patients have a decompensated cardiac status.

The authors conducted structured interviews with end users (housestaff, pharmacists, nurses, nurse managers, and attending physicians), real-time observations of end users interfacing with the system, entering orders, charting medications, and reviewing orders, and focus groups with housestaff. These qualitative data were used to help generate a 71-question structured survey subsequently given to the housestaff. These questions pertain to working conditions, sources of stress, and errors. There were 261 responses representing an 88% response rate.

Twenty-two previously unexplored potential medication error sources abstracted from the survey were grouped into the 2 categories: 1) information errors, and 2) human-machine interface flaws. The first category refers to fragmented data and the disparate information systems within hospitals. The latter category includes rigid machine programming that does not correspond to or facilitate workflow. Only 10 survey elements with sufficiently robust results were reported. About 40% of respondents used CPOE to determine dosage of infrequently prescribed medications at least once a week or more. Incorrect doses may be ordered if users follow the dosage information in the system that is based on drug inventory rather than clinical recommendations. Twenty-two percent of respondents noted that more than once a week duplicate or conflicting medications were ordered and not detected for several hours. Disorganized display of patient medications was believed to be partly responsible. More than 80% of respondents noted unintended delay in renewing antibiotics at least once. Such gaps were possible partially because the reminder system occurred in the paper chart while order entry was done with the computer. With respect to the human-machine interface, 55% reported difficulty identifying the correct patient because of poor or fragmented displays, and 23% reported this occurring more than a few times per week. System downtime leading to delay in order entry was reported by 47% to occur more than once a week. System inflexibility also led to difficulties in specifying medications and ordering nonformulary medications. This was reported by 31% to occur at least several times a week, and 24% reported this daily or more frequently.

This was a survey of end users of a CPOE system in a single institution, and the survey elements were mainly estimates of error risks. Nevertheless, it appropriately draws attention to the importance of the unique culture of each institution, efficient workflow, and coherent human-machine interface. The anticipated error reductions may not materialize if these issues are neglected. Hospitalists can serve a critical role in implementation and customization of CPOE systems that allow clinicians to do the right thing more timely and efficiently.

Risk Stratification for In-hospital Mortality in Acutely Decompensated Heart Failure: Classification and Regression Tree Analysis

Fonarow GC, Adams KF, Abraham WT, Yancy CW, Boscardin WJ; ADHERE Scientific Advisory Committee, Study Group, and Investigators. Risk stratification for in-hospital mortality in acutely decompensated heart failure: classification and regression tree analysis. JAMA. 2005;293:572-80.

Heart failure is an important and growing cause of hospitalization in this country, and it is one of the most common clinical entities encountered by hospitalists. While there are some risk assessment tools available for outpatients with heart failure, there has not been a risk stratification tool published for inpatients. In this study by Fonarow et al. in JAMA, the authors describe a simple risk-stratification formula for in-hospital mortality in patients with acutely decompensated heart failure. Data from the ADHERE registry (Acute Decompensated Heart Failure National Registry, which is industry sponsored, as was this study) were used to model the risk of in-hospital death using a classification and regression tree (CART) analysis. This was done in a 2-stage process. First, investigators established a derivation cohort of approximately 33,000 patients (sequential hospital admissions from October 2001 to February 2003) from the ADHERE registry, and used the CART method to analyze 39 clinical variables to determine which were the best predictors of in-hospital mortality. This analysis was used to derive a risk tree to partition patients into low-, intermediate-, and high-risk groups. Second, the validity of this method was tested by applying the prediction tool to a cohort of the subsequent 32,229 patients hospitalized in the ADHERE registry, from March 2003 to July 2003. The results were striking. Baseline characteristics and clinical outcomes between the derivation and validation cohorts were similar across the wide range of parameters examined. The difference in mortality between the low-, intermediate-, and high-risk groups was 23.6% in the highest-risk category and 1.8% in the low-risk category, while the intermediate group was stratified into 3 levels, with 20.0%, 5.0%, and 5.1% mortality risk in intermediate group levels 1, 2, and 3, respectively. Aside from the more than 10-fold range in mortality risk across the various groups, the outstanding feature of the authors’ findings was that 3 simple parameters were the most significant predictors of in-hospital mortality risk: BUN, SBP, and serum creatinine. Specifically, combinations of a serum BUN of 43 or greater, a serum creatinine of 2.75 or greater, and a systolic blood pressure of less than 115 were associated with higher mortality. They note that adding other predictors did not meaningfully increase the model’s accuracy. The authors comment that unlike other predictive models based on multivariate analyses (which are often complex, and therefore difficult to employ at bedside), this simple tool is easy to use. An additional advantage is that the data needed are typically available at time of admission and can therefore be used to make a timely clinical decision in terms of triage into an appropriate level of care. Similar risk assessment tools exist for the risk stratification of patients with the acute coronary syndrome, and given the frequency with which patients are admitted with acutely decompensated heart failure, this new tool should prove a welcome addition to the clinical decision-making abilities of hospitalists.

 

 

Risk of Endocarditis among Patients with Prosthetic Valves and Staphylococcus Aureus Bacteremia

El-Ahdab F, Benjamin DK, Wang A, , et al. Risk of endocarditis among patients with prosthetic valves and Staphylococcus aureus bacteremia. Am J Med. 2005;118:225-9.

The risk of developing endocarditis in patients with Staphylococcus aureus bacteremia and prosthetic valves increases as more than 600,000 prosthetic valves are implanted annually in the United States. A prospective study at Duke University identified 51 patients with prosthetic valves or mitral ring who developed S. aureus bacteremia. The modified Duke criteria were used for the diagnosis of endocarditis. The onset and sources of bacteremia, locations of acquiring bacteremia, as well as clinical outcome were analyzed. The overall incidence of definite prosthetic valve endocarditis was as high as 51%, with the remaining 49% patients meeting Duke criteria for possible endocarditis. The results showed that endocarditis occurred more frequently in mitral (62%) and aortic positions (48%), and with mitral ring the rate of endocarditis was slightly lower (33%). Among prostheses, mechanical and bioprosthetic valves had endocarditis rates of 62% and 44%, respectively. About 63% of patients had early onset of bacteremia (<1 year after valve placement), and 37% had late onset of bacteremia (>1 year after valve placement). Overall, the most common source of bacteremia was from infected surgical wound sites (33%). Early bacteremia was more likely to result from infected surgical wound sites (59%), while late bacteremia was more likely to have an unidentified source (48%). The majority of episodes of bacteremia (47%) were hospital-acquired (i.e., a positive blood culture occurred >72 hours after admission). The frequency of healthcare-associated bacteremia and community-acquired bacteremia was about 26%–27%.

In terms of mortality, there was no difference for a patient with early and late S. aureus bacteremia, bioprosthetic and mechanical valves, and infection due to methicillin-resistant or methicillin-susceptible S. aureus. However, mortality was higher among patients with definite endocarditis (62%) vs. possible endocarditis (28%). Patients with endocarditis who underwent valve surgery had lower mortality than those who did not undergo valve surgery due to inoperable comorbid conditions, such as stroke, multiorgan system failure, and mediastinitis. Persistent fever (≥ 38°C after 72 hours of adequate parenteral antibiotics) and persistent bacteremia (positive blood culture within 2–4 days of the initial positive blood culture) were independently associated with definite endocarditis with odds ratio of 4.4 and 11.7, respectively. Overall, 96% of patients underwent echocardiography (55% with both transesophageal and transthoracic echo, 14% with only transesophageal echo, 27% with only transthoracic echo). However, 10% patients with definite endocarditis had no diagnostic finding on either transthoracic or transesophageal echocardiography.

S. aureus bacteremia is a common phenomenon in inpatient settings. This study demonstrated an approximately 50% rate of definite prosthetic valve endocarditis in patients with S. aureus bacteremia. The risks of endocarditis were independent of valve type, location, and duration of implantation. This study highlights the need for aggressive treatment and evaluation of S. aureus bacteremia in patients with prosthetic valves. Clinically, persistent fever and bacteremia were independently associated with definite endocarditis in this study population. Clinicians cannot over-rely on transesophageal echocardiogram to identify occult endocarditis in high-risk patients.

Optimizing the Prediction of Perioperative Mortality in Vascular Surgery by Using a Customized Probability Model

Kertai MD, Boersma E, Klein J, van Urk H, Poldermans D. Optimizing the prediction of perioperative mortality in vascular surgery by using a customized probability model. Arch Intern Med. 2005;165:898-904.

Traditional perioperative risk-assessment models and indexes have focused primarily on cardiac outcomes and involved mainly clinical risk factors. The model proposed in this paper focused instead on overall mortality and incorporated not only clinical risk factors but also more precise surgery-specific risks and the use of beta-blocker and statin agents.

Investigators in the Netherlands targeted only vascular surgery patients identified from a computerized hospital information system. From a system, 2,310 patients who underwent 2,758 noncardiac vascular surgeries during a 10-year period in the 1990s were selected. Clinical risk factors, data on noninvasive stress testing, and long-term medication use, including statin agents, beta-blockers, calcium channel blockers, diuretics, insulin, nitrate, and aspirin, were abstracted. Outcome measures were all-cause mortality before discharge or within 30 days after surgery. The proposed model (see Figure) was based on modifications of the original Goldman Index, with the addition of more precise surgery risk stratification and statin and beta-blocker use. The specific types of vascular surgeries: carotid endarterectomy, infrainguinal bypass, abdominal aortic surgery, thoracoabdominal surgery, and acute abdominal aortic aneurysm rupture repair, carried systematically increased risk in expected fashion. Upon univariate analysis in the derivation cohort (n = 1,537), most of the clinical predictors from the Goldman Index were associated with increased perioperative mortality. Similar conclusions persisted in multivariate logistic regression analysis. Risk of surgical procedures, cardiovascular morbidity (ischemic heart disease, congestive heart failure, history of cerebrovascular event, and hypertension), renal dysfunction, and chronic pulmonary disease are independent predictors of increased all-cause perioperative mortality. In contrast, use of beta-blockers and statins were associated with reduced incidence of perioperative mortality. The final model included a scoring system with points assigned according to risk estimates of individual predictors. Beta-blocker and statin use in this model are assigned negative scores as their use lowers risk. For example, a patient with ischemic heart disease and hypertension undergoing abdominal aortic surgery would have a score of 46, corresponding to a 14% probability of mortality. That risk would be reduced to about 4% (score of 31) by use of beta-blockers (−15). In the same database, with 773 patients as the validation cohort, this prediction model performed nearly as well as the derivation model. Hypertension was not found to be an independent predictor in this validation cohort.

This tool appears provide robust risk assessment for vascular surgery patients. The inclusion of estimated benefit-of-statin and beta-blocker use may allow a more accurate “net” risk assessment. Those patients who are already on these 2 agents but still deemed at higher risk can be informed and may benefit from close monitoring. Additional preoperative interventions may include revascularization, if these high-risk patients have a decompensated cardiac status.

Case Presentation

A 68-year-old man presented to a university hospital with a 4-day history of sudden, progressive finger ischemia. His past medical history was significant for type II diabetes mellitus and hyperlipidemia. He also suffered from severe vascular disease. Four years prior to admission, he underwent several surgeries, including right carotid endarterectomy, coronary artery bypass, and right-lower-extremity revascularization. One year prior, he also required a left below-the-knee amputation due to vascular insufficiency. Additional history revealed long-standing asthma, hearing loss due to chronic bilateral otitis media, and multiple sinus surgeries in attempts to relieve recurrent infections. He also had lower-extremity peripheral neuropathy, attributed to diabetes and frequent steroid use for asthma control.

Figure 1.

Figure 2.

On admission, vital signs were stable. Physical exam demonstrated mild cyanosis of digits 2 through 5 on both hands. There were also scattered splinter hemorrhages and petechiae on the involved fingers. Rales were noted in the left lung base with diffuse wheezes. Cardiac and vascular exams were unremarkable. Chronic ulceration of the right toes was also noted. Laboratory studies were significant for a white blood cell count of 26,700 cells/mL with 52% eosinophils and a positive perinuclear antineutrophil cytoplasmic antibody (p-ANCA).

A chest radiograph revealed hazy, bilateral perihilar and left lower lobe infiltrates (Figure 1). Computed tomography of the chest was then performed and showed bronchiectasis of the left lung (Figure 2). This prompted a transbronchial biopsy that yielded tissue consistent with chronic inflammation.

Churg-Strauss Syndrome

Discussion

Churg-Strauss syndrome (CSS) is an allergic and granulomatous vasculitic illness affecting multiple organ systems. It typically follows 3 phases of progression. The first occurs in the second or third decade of life and includes the development of asthma in addition to chronic ear, nose, and sinus inflammation or infection. This is followed by eosinophilic infiltration of the lungs, skin, and other organs. The third phase commonly occurs 10 to 20 years after initial presentation, and it is heralded by small- and medium-vessel vasculitis.

In 1990, the American College of Rheumatology developed 6 diagnostic criteria for CSS and showed that having at least 4 of the 6 predicted the presence of CSS with a sensitivity of 85% and a specificity of 99.7%. They include:

  • Asthma;
  • Eosinophilia of >10% on a peripheral white blood cell count;
  • Paranasal sinus disease;
  • Mononeuropathy or polyneuropathy;
  • Migratory or transient pulmonary opacities seen radiographically; and
  • A blood vessel showing the accumulation of eosinophils in extravascular areas, as revealed by a biopsy.

Other helpful, but nonspecific diagnostic tests include a significantly elevated sedimentation rate, a positive p-ANCA with low titers of rheumatoid factor, high circulating IgE levels, and normocytic, normochromic anemia. CSS typically responds quite well to immunosuppressive therapy. The usual regimen consists of corticosteroids, and cyclophosphamide is frequently added. Before the advent of such therapies, CSS was consistently fatal, often within 3 months of the onset of vasculitis. Currently, 5-year survival rates exceed 70%.

In this patient, a diagnosis of CSS was based on history, clinical presentation, and laboratory results. Highdose methylprednisolone was initiated, and complete resolution of finger cyanosis and pain occurred in 48 hours. Oral cyclophosphamide was added the following day, and the patient was discharged home to complete 6 months of aggressive immunosuppressive therapy.

This presentation of CSS was rather unusual. Digital ischemia is uncommon in CSS, although it is consistent with the small-vessel vasculitis seen in this syndrome. Similarly, the late onset of the patient’s vasculitis is also unusual. The intermittent use of prednisone for asthma perhaps delayed the declaration of systemic symptoms.
