Background: Delirium is commonly seen in the ICU and has been associated with increased morbidity and mortality. While haloperidol, as well as atypical antipsychotics, often are used to manage ICU delirium, evidence has been mixed as to whether these medications shorten the duration of either hyperactive or hypoactive delirium.

Only 11% of patients experienced hyperactive delirium, which makes these results less generalizable to patients whose delirium presents as agitation.

Bottom line: The use of antipsychotics in ICU delirium does not affect the duration of delirium in patient with respiratory failure or shock.

BANGKOK – Statin therapy, even when initiated only upon hospitalization for acute ischemic stroke, was associated with a striking reduction in the risk of early poststroke symptomatic seizure in a large observational study.

Bruce Jancin/MDedge News

Using propensity-score matching to control for potential confounders, use of a statin during acute stroke management was associated with a “robust” 77% reduction in the risk of developing a symptomatic seizure within 7 days after hospital admission, Soichiro Matsubara, MD, reported at the International Epilepsy Congress.

This is an important finding because early symptomatic seizure (ESS) occurs in 2%-7% of patients following an acute ischemic stroke. Moreover, an Italian meta-analysis concluded that ESS was associated with a 4.4-fold increased risk of developing poststroke epilepsy (Epilepsia. 2016 Aug;57[8]:1205-14), noted Dr. Matsubara, a neurologist at the National Cerebral and Cardiovascular Center in Suita, Japan, as well as at Kumamoto (Japan) University.

He presented a study of 2,969 consecutive acute ischemic stroke patients with no history of epilepsy who were admitted to the Japanese comprehensive stroke center, of whom 2.2% experienced ESS. At physician discretion, 19% of the ESS cohort were on a statin during their acute stroke management, as were 55% of the no-ESS group. Four-fifths of patients on a statin initiated the drug only upon hospital admission.

Strokes tended to be more severe in the ESS group, with a median initial National Institutes of Health Stroke Scale score of 12.5, compared with 4 in the seizure-free patients. A cortical stroke lesion was evident upon imaging in 89% of the ESS group and 55% of no-ESS patients. Among ESS patients, 46% had a cardiometabolic stroke, compared with 34% of the no-ESS cohort. Mean C-reactive protein levels and white blood cell counts were significantly higher in the ESS cohort as well. Their median hospital length of stay was 25.5 days, versus 18 days in the no-ESS group, Dr. Matsubara said at the congress sponsored by the International League Against Epilepsy.

Of the 76 ESSs that occurred in 66 patients, 37% were focal awareness seizures, 35% were focal to bilateral tonic-clonic seizures, and 28% were focal impaired awareness seizures.

In a multivariate analysis adjusted for age, sex, body mass index, stroke subtype, and other potential confounders, statin therapy during acute management of stroke was independently associated with a 56% reduction in the relative risk of ESS. In contrast, a cortical stroke lesion was associated with a 2.83-fold increased risk.

Since this wasn’t a randomized trial of statin therapy, Dr. Matsubara and his coinvestigators felt the need to go further in analyzing the data. After extensive propensity score matching for atrial fibrillation, current smoking, systolic blood pressure, the presence or absence of a cortical stroke lesion, large vessel stenosis, and other possible confounders, they were left with two closely comparable groups: 886 statin-treated stroke patients and an equal number who were not on statin therapy during their acute stroke management. The key finding: The risk of ESS was reduced by a whopping 77% in the patients on statin therapy.

The neurologist observed that these new findings in acute ischemic stroke patients are consistent with an earlier study in a U.S. Veterans Affairs population, which demonstrated that statin therapy was associated with a significantly lower risk of new-onset geriatric epilepsy (J Am Geriatr Soc. 2009 Feb;57[2]:237-42).

As to the possible mechanism by which statins may protect against ESS, Dr. Matsubara noted that acute ischemic stroke causes toxic neuronal excitation because of blood-brain barrier disruption, ion channel dysfunction, altered gene expression, and increased release of neurotransmitters. In animal models, statins provide a neuroprotective effect by reducing glutamate levels, activating endothelial nitric oxide synthase, and inhibiting production of interleukin-6, tumor necrosis factor-alpha, and other inflammatory cytokines.

Asked about the intensity of the statin therapy, Dr. Matsubara replied that the target was typically an LDL cholesterol below 100 mg/dL.

He reported having no financial conflicts regarding the study, conducted free of commercial support.

I had just received my sign-out for the day. My pager beeped, and I heard it overhead “Code Blue Room X.” Hospitalist physicians lead the code team in our hospital; I quickly headed to the room.

A young man in his forties was found to be unconscious on the floor. One of the nurses had started cardiopulmonary resuscitation (CPR) as the patient was unconscious and had no palpable pulse. It was a long, drawn-out battle: CPR, cracking bones, shouting, lots of needles – an extreme roller-coaster-style situation. The patient had recently had a hip surgery and our suspicion was a massive pulmonary embolism. We ran the exhaustive code for more than an hour and then I started to debrief with my code team; discussed that treatment was getting futile and asked for opinions. Finally, I asked the team to stop and pronounced the patient dead. I felt terrible. Later that day I returned to my house, tossed my bag in the corner, and sympathized with myself – “Hello Dr. B, It was a tough one.”

Stopping resuscitation was one of the toughest decisions I had ever made, and I wondered if I would be able to make such a decision the next day. What if I had carried on? I had led code teams during my residency training and as an attending physician; but there was something different that day. This patient was a young man with no history of medical problems. Every physician knows how to initiate resuscitation for cardiopulmonary arrest (CPA); only a few know when to stop it. Did I miss this learning during my internal medicine training? I checked my red pocket leaflet with advanced cardiac life support (ACLS) algorithms, and it had no mention of it. I searched Google Scholar, PubMed, and UpToDate and surprisingly, I found no predetermined rule but only a few recommendations on when CPR should be stopped. The American Heart Association is clear that the decision to terminate resuscitative efforts rests with the treating physician in the hospital.

In my experience, the length of time to continue a code can vary widely and is mostly dependent on the physician running the code. I have seen it last 15 minutes (which is reasonable) and I have seen it last for 50 minutes when the initial rhythm was ventricular fibrillation. And if perhaps the patient regains a pulse temporarily, only to lose it again, we restart the clock. One needs to take into account various factors including time to CPR, time to defibrillation, comorbid disease, prearrest state, and initial arrest rhythm in making these decisions. It’s well understood that none of these factors alone or in combination is clearly predictive of outcome.¹

Some selected patients potentially have good outcomes with prolonged, aggressive resuscitation. So when should we stop, and when should we continue resuscitation? This is always challenging. Physicians hate to stop CPR even when they know it’s time. We are guided by the Hippocratic Oath to save lives. Sometimes, even if we want to stop, we tend to continue to avoid being criticized for stopping; we are systematically biased against stopping CPR. We routinely run long codes, in part because we are not sure which patients we can bring back.

A 2012 Lancet study highlighted that the median duration of resuscitation was 12 minutes for patients achieving the return of spontaneous circulation and 20 minutes for nonsurvivors.² The ethical guidelines issued by AHA in 2018 highlight that, in the absence of mitigating factors, prolonged resuscitative efforts for adults and children are unlikely to be successful and can be discontinued if there is no return of spontaneous circulation at any time during 30 minutes of cumulative ACLS. If the return of spontaneous circulation of any duration occurs at any time, however, it may be appropriate to consider extending the resuscitative effort.³

I believe a careful balance of the patient’s prognosis for both length of life and quality of life will determine whether continued CPR is appropriate. The responsible clinician should stop the resuscitative effort when he or she determines with a high degree of certainty that the arrest victim will not respond to further efforts. But what will help me guide my decisions next time if I ever come across this situation again?

I discussed my dilemma with one of our intensivist physicians; he expressed that in a similar scenario he would ask for opinions from other members of the code team. The role of good communication among code team members is necessary to exchange relevant knowledge in real time in a collaborative, nonhierarchical environment. The code team can provide the team leader with quick, accurate information about the patient’s clinical history that is critical to good decision making.

Family support is also an essential part of any resuscitation. Health care providers need to offer the opportunity to be present to family members during the resuscitation attempts whenever possible. One team member should be assigned to the family to answer questions, clarify information, and offer comfort, but physicians should not be asking family members to decide to stop the code. It is important to note that the decision should be made by the team leader and not the patient’s family members. Regardless of the age or condition of the patient, the loss of a loved one is difficult to deal with, even if expected. The issue becomes more difficult with changes in legal, cultural, or personal perspectives.

The AHA in 2018 stated that the treating physician is expected to understand the patient and the arrest features, and the system factors that have prognostic importance for resuscitation.³ For clinicians who work in critical care settings, the framework presented by AHA is intuitive. As a code leader, I can always give more epinephrine, try a clot-busting drug or deliver another shock. Situations vary greatly during a code, and the amount of time spent resuscitating a patient before terminating efforts is not set in stone. In many cases, it is a judgment call. The process of CPR is almost as disheartening as its bleak outcomes.

In-hospital CPAs are inevitably gruesome. Each day as an attending physician, we are faced with difficult decisions, but experiencing these incredibly difficult and life-changing events can make for good learning. A CPA situation in action is very difficult for all concerned, particularly when there is almost no chance of success. But an unsuccessful or aborted resuscitation is also a huge loss for both the family and the code team. One of the critical functions of the code team leader is to review the events of a code and exercise judgment while evaluating the length of a code. This can be an intense and emotional experience, but with these principles in mind, we can feel reassured that we are making the best decision possible, for the patient, the family, and our team.

Situations vary greatly during a code, and the amount of time spent resuscitating a patient before terminating efforts is not set in stone. In many cases, it is a judgment call. The process of CPR is almost as disheartening as its bleak outcomes.

In-hospital CPAs are inevitably gruesome. Each day as an attending physician, we are faced with difficult decisions, but experiencing these incredibly difficult and life-changing events can make for good learning. A CPA situation in action is very difficult for all concerned, particularly when there is almost no chance of success. But an unsuccessful or aborted resuscitation is also a huge loss for both the family and the code team. One of the critical functions of the code team leader is to review the events of a code and exercise judgment while evaluating the length of a code. This can be an intense and emotional experience, but with these principles in mind, we can feel reassured that we are making the best decision possible, for the patient, the family, and our team.

Background: Acute cystitis is a common condition in women and associated with morbidity. A commonly recommended preventative measure is increased oral hydration, but there is limited evidence to support this claim.

Though antibiotic prophylaxis is more effective at reducing cystitis, increased daily water intake is a safe and inexpensive method to prevent cystitis without increasing exposure to antimicrobial therapy. This study did rely on information obtained from phone calls with patients. It is also an open-label study design in which patients were not blinded to their assigned group. This would be less of an issue if episodes of cystitis were confirmed with culture. Another limitation of this study is that it included only ambulatory patients and excluded patients with pyelonephritis, so it may be less applicable to our hospitalized patients.

Bottom line: This study shows a benefit in recurrent cystitis by increased water intake in premenopausal women.

Both systolic and diastolic hypertension independently predict myocardial infarction and strokes, but systolic blood pressure is more strongly linked to adverse outcomes.

That’s according to a study of more than 1 million patients and 36 million outpatient blood pressure measurements published in the New England Journal of Medicine.

Systolic and diastolic hypertension predicted adverse outcomes at cutpoints of 140/90 and 130/80 mm Hg in the large retrospective cohort study, supporting the recent guideline changes that made blood pressure targets more stringent for higher-risk patients, said lead investigator Alexander C. Flint, MD, of Kaiser Permanente Northern California (KPNC) in Oakland.

“While systolic does count for more, in the fact that it is a stronger driver of the risk of heart attack and stroke, diastolic absolutely does as well, and it does so independently. So we ignore our diastolic hypertension at our own peril,” Dr. Flint said in an interview.

Systolic hypertension began to overshadow diastolic after the Framingham Heart Study and others that suggested it is a more important predictor of adverse cardiovascular outcomes, Dr. Flint and coauthors said in a report on their study.

Those findings caused some to say diastole should be abandoned, and led to a “near-exclusive focus” on systolic hypertension in a 2000 advisory statement from the National High Blood Pressure Education Program, they say in their report.

While current guidelines emphasize the importance of both systolic and diastolic targets, many clinicians today often assign little importance to diastolic blood pressure values, the report adds.

“The pendulum needs to swing back, right down in the middle,” Dr. Flint said in the interview.

The study by Dr. Flint and colleagues comprised a cohort of approximately 1.3 million outpatients from KPNC who had at least one baseline blood pressure reading in during 2007-2008, and two or more follow-up measurements between 2009 and 2016, for a total of about 36.8 million data points.

Systolic hypertension burden was linked to the composite of MI or stroke, with a hazard ratio of 1.18 (95% confidence interval, 1.17-1.18; P less than .001) per unit increase in z score, according to results of a multivariable regression analysis. Likewise, diastolic hypertension burden was linked to those adverse outcomes, with a hazard ratio of 1.06 (95% CI, 1.06-1.07; P less than .001).

Put in terms of estimated risk of MI or stroke, patients with a systolic blood pressure around 160 mm Hg – 3 standard deviations from the mean – was 4.8%, compared to a predicted risk of just 1.9% for a systolic blood pressure near 136 mm Hg, the investigators said in their report.

Similarly, predicted risk was 3.6% for a diastolic pressure of about 96 mm Hg, also 3 standard deviations from the mean, and 1.9% for a diastolic BP near 81 mm Hg.

“The two are not that separate,” Dr. Flint said of the risks associated with systolic and diastolic hypertension at that 3-standard-deviation point. Beyond that, increased systolic blood pressure is associated with more risk relative to increased diastolic blood pressure, the logistic regression modeling shows.

Taken together, findings from this large cohort study emphasize the importance of making lifestyle modifications and adjusting medication to ensure that both systolic and diastolic targets are met, according to Dr. Flint.

“Rises in systolic blood pressure count for more in influencing the risk of heart attack and stroke,” he said, “but diastolic independently counts for quite a lot. It’s a close second.”

Dr. Flint reported no disclosures. Senior author Deepak L. Bhatt, MD, MPH, reported disclosures with Amarin, AstraZeneca, Bristol-Myers Squibb, Eisai, Ethicon, Medtronic, Sanofi Aventis, Takeda, The Medicines Company, and others. The remaining authors had no disclosures.

Although guideline recommended, treating children in shock with a bolus of saline or albumin fluid imposes counterproductive effects on respiratory and neurologic function, ultimately increasing risk of death, according to a detailed analysis of available data, including a randomized trial.

Several sets of guidelines for resuscitation of patients in shock have advocated volume expansion with bolus intravenous fluid, but that recommendation was based on expected physiologic benefits not a randomized trial. The only randomized trial associated this approach showed increased mortality, and a new analysis of these and other data appears to explain why.

According to the findings of a study lead by Michael Levin, MD, of the department of medicine at Imperial College London and colleagues, “volume resuscitation is associated with deterioration of respiratory function and neurological function in some patients.” Their study was published in Lancet Respiratory Medicine. The authors stated that saline-induced hyperchloremic acidosis appears to have been “a major contributor” to the observed increase in adverse outcomes.

The key take home message is that “normal saline and other unbuffered crystalloid solutions should be avoided in resuscitating seriously ill patients,” according to the authors, who believe the findings might be relevant to adults as well as children.

The controversy about the role of volume expansion for management of shock was ignited by a 2011 trial called FEAST (N Engl J Med. 2011;364:2483-95). That trial, which randomized African children with severe febrile illness to a bolus of 20-40 mg of 5% albumin solution, a bolus of 0.9% saline solution, or no bolus, was halted early when 48-hour mortality data showed a lower death rate in the no bolus group (7.3%) than either the albumin (10.6%) or saline (10.5%) bolus groups.

The FEAST result was unexpected and so contrary to accepted thinking that it prompted widespread debate, including whether findings in the resource-poor area of the world where the FEAST trial was conducted could be extrapolated to centers elsewhere in the world. Arguing for benefit, fluid resuscitation is known to increase pulse pressure and urinary output. Arguing against benefit, pulmonary edema is a known complication of bolus fluid replacement.

In an attempt to address and potentially resolve this controversy, data collected in the FEAST trial along with four other sets of data involving volume expansion in critically ill children were evaluated with a focus on changes in cardiovascular, neurological, and respiratory function. Analysis of blood biochemistry and blood oxygen transport were also conducted.

The cardiovascular, respiratory, and neurologic functions were scored on the basis of objective measurements, such as heart rate, respiratory rate, and blood pressure. These measures were evaluated prior to fluid administration and at 1 hour, 4 hours, 8 hours, 24 hours, and 48 hours after fluid administration. Odds ratio (OR) of an adverse outcome were evaluated in the context of each 10-unit change in these scores.

Relative to baseline, there was worsening respiratory and neurological function after fluid administration. Although cardiovascular function improved, hemoglobin concentrations were lower in those who received fluid than in those who did not. Fluid resuscitation was also associated with lower bicarbonate and increased base deficit and chloride at 24 hours.

Regression modeling with physiological variables suggests “that the increased mortality in FEAST can be explained by bolus-induced worsening in respiratory and neurological function, hemodilution, and hyperchloremic acidosis,” according to the authors.

Analyses of the four other sets of data, which included children treated for meningococcal sepsis in the United Kingdom, acutely ill with malaria treated in Malawi, and cohorts of children in South Africa and a London hospital for acute illnesses, provided supportive data.

Although this analysis does not address the value of administering buffered solutions in low volumes, the authors concluded that the data from the FEAST trial are generalizable. They challenge the routine use of bolus infusions of saline or albumin in the initial management of shock, which has been guideline recommended. The risks of fluid resuscitation might be particularly high among children who already have compromised respiratory or neurologic function.

The Food and Drug Administration has approved Recarbrio for the treatment of complicated urinary tract infections (cUTI) and complicated intra-abdominal infections (cIAI) in adults. Recarbrio is a three-drug combo injection containing imipenem/cilastatin, an antibiotic previously approved by the FDA, and relebactam, a beta-lactamase inhibitor.

The efficacy of Recarbrio was supported by data on the efficacy of imipenem/cilastatin in the treatment of cUTI and cIAI and by in vitro studies and animal models of infection with treatment by relebactam. The safety was assessed in a pair of clinical studies, one that assessed cUTI patients and another that assessed cIAI patients.

The most common adverse events reported were nausea, diarrhea, headache, fever, and increased liver enzymes. Treatment with Recarbrio is not recommended in patients taking ganciclovir, valproic acid, or divalproex sodium because there is an increased risk of seizures, according to the FDA.

“The FDA remains focused on facilitating the development of safe and effective new antibacterial drugs to give patients more options to fight serious infections. It is important that the use of Recarbrio be reserved for situations when there are limited or no alternative antibacterial drugs for treating a patient’s infection,” Ed Cox, MD, MPH, director for the Office of Antimicrobial Products in FDA’s Center for Drug Evaluation and Research, said in the press release.

Non–vitamin K oral anticoagulants (NOACs) significantly reduced the risk of stroke or systemic embolism compared to vitamin K antagonists (VKAs) for patients in the early stages of chronic kidney disease and comorbid atrial fibrillation, based on data from a meta-analysis of roughly 34,000 patients.

Chronic kidney disease increases the risk of complications including stroke, congestive heart failure, and death in patients who also have atrial fibrillation, but most trials of anticoagulant therapy to reduce the risk of such events have excluded these patients, wrote Jeffrey T. Ha, MBBS, of the George Institute for Global Health, Newtown, Australia, and colleagues.

To assess the benefits and harms of oral anticoagulants for multiple indications in chronic kidney disease patients, the researchers conducted a meta-analysis of 45 studies including 34,082 individuals. The findings were published in the Annals of Internal Medicine. The analysis included 8 trials of end stage kidney disease patients on dialysis; the remaining trials excluded patients with creatinine clearance less than 20 mL/min or an estimated glomerular filtration rate less than 15 mL/min per 1.73 m². The interventional agents were rivaroxaban, dabigatran, apixaban, edoxaban, betrixaban, warfarin, and acenocoumarol.

A notable finding was the significant reduction in relative risk of stroke or systemic embolism (21%), hemorrhagic stroke (52%), and intracranial hemorrhage (51%) for early-stage chronic kidney disease patients with atrial fibrillation given NOACs, compared with those given VKAs.

The evidence for the superiority of NOACs over VKAs for reducing risk of venous thromboembolism (VTE) or VTE-related death was uncertain, as was the evidence to draw any conclusions about benefits and harms of either NOACs or VKAs for patients with advanced or end-stage kidney disease.

Across all trials, NOACs appeared to reduce the relative risk of major bleeding, compared with VKAs by roughly 25%, but the difference was not statistically significant, the researchers noted.

The findings were limited by the lack of evidence for oral anticoagulant use in patients with advanced chronic or end-stage kidney disease, as well as inability to assess differences among NOACs, the researchers noted. However, the results suggest that NOACs may be recommended over VKAs for the subgroup of early-stage chronic kidney disease patients with atrial fibrillation, they said.

Several additional trials are in progress, and future trials “should include not only participants with dialysis-dependent ESKD [end-stage kidney disease] but also those with CrCl [creatinine clearance of] less than 25 mL/min,” and compare NOACs with placebo as well, they noted.

Non–vitamin K oral anticoagulants (NOACs) significantly reduced the risk of stroke or systemic embolism compared to vitamin K antagonists (VKAs) for patients in the early stages of chronic kidney disease and comorbid atrial fibrillation, based on data from a meta-analysis of roughly 34,000 patients.

Chronic kidney disease increases the risk of complications including stroke, congestive heart failure, and death in patients who also have atrial fibrillation, but most trials of anticoagulant therapy to reduce the risk of such events have excluded these patients, wrote Jeffrey T. Ha, MBBS, of the George Institute for Global Health, Newtown, Australia, and colleagues.

To assess the benefits and harms of oral anticoagulants for multiple indications in chronic kidney disease patients, the researchers conducted a meta-analysis of 45 studies including 34,082 individuals. The findings were published in the Annals of Internal Medicine. The analysis included 8 trials of end stage kidney disease patients on dialysis; the remaining trials excluded patients with creatinine clearance less than 20 mL/min or an estimated glomerular filtration rate less than 15 mL/min per 1.73 m². The interventional agents were rivaroxaban, dabigatran, apixaban, edoxaban, betrixaban, warfarin, and acenocoumarol.

AUSTIN, TEX. – The majority of skin-related pediatric inpatient admissions in the United States involve treatment for cellulitis, results from a large study of national data showed.

“Skin conditions significantly affect pediatric inpatients, and dermatologists ought be accessible for consultation to enhance care and costs,” the study’s first author, Marcus L. Elias, said in an interview prior to the annual meeting of the Society for Pediatric Dermatology.

According to Mr. Elias, who is a 4th-year medical student at Rutgers New Jersey Medical School–Newark, few national studies on skin diseases for pediatric inpatients have been published in the medical literature. Earlier this year, researchers examined inpatient dermatologic conditions in patients aged 18 years and older (J Am Acad Dermatol 2019;80[2]:425-32), but Mr. Elias and associates set out to analyze the burden of inpatient pediatric dermatologic conditions on a national basis. “We wanted to see if the same conditions that were hospitalizing adults were also hospitalizing kids,” he said. “We found that this was indeed the case.”

The researchers queried the National Inpatient Sample database for all cases involving patients aged 18 years and younger during 2001-2013. The search yielded a sample of 16,837,857 patients. From this, the researchers analyzed diagnosis-related groups for dermatologic conditions denoting the principal diagnosis at discharge, which left a final sample of 84,090 patients. Frequency and chi-squared tests were used to analyze categorical variables.

More than half of patients (54%) were male, 36% were white, 48% had Medicaid insurance, and 43% had private insurance. Mr. Elias reported that the median length of stay for patients was 2 days and the median cost of care was $6,289.50 for each case. More than three-quarters of pediatric inpatients with dermatologic diagnoses were treated for “cellulitis” (66,147 cases, or 79%), with most cases involving the legs (16,875 cases, or 20%). Other pediatric inpatients were admitted for “minor skin disorder without complications” (5,458 cases, or 7%), and “minor skin disorder with complications” (2,822 cases, or 3%). A total of 64 patients died during the study period. Of these, 31 cases (50%) involved “skin graft and/or debridement of skin ulcer or cellulitis without complications,” the study found.

“We were surprised that the major cause of mortality for our patients was classified as ‘skin graft and/or debridement of skin ulcer or cellulitis without complications,’ as a similar diagnosis-related groupings exist denoting that complications did arise,” Mr. Elias said. “Still, it is not possible for us to determine if the mortality was from the skin graft/debridement or another cause entirely. It is possible that the procedure was without complications, only to have the patient succumb to an ancillary process.”

He acknowledged certain limitations of the study, including the fact that the function of dermatologic consults for hospitalized patients was not examined. “We also cannot draw conclusions as to whether improved outpatient therapy reduces the need for hospitalization,” he said. Mr. Elias reported having no financial disclosures.

Patients with chronic obstructive pulmonary disease are at a significantly increased risk for hospitalization for community-acquired pneumonia (CAP), compared with patients without COPD, a large prospective study has found.

Jose Bordon, MD, and colleagues aimed to define incidence and outcomes of COPD patients hospitalized with pneumonia in the city of Louisville, Ky., and to extrapolate the burden of disease in the U.S. population. They conducted a secondary analysis of data from the University of Louisville Pneumonia Study, a prospective population-based cohort study of all hospitalized adults with CAP who were residents in the city of Louisville, Ky., from June 1, 2014, to May 31, 2016.

COPD prevalence in the city of Louisville was derived via data from the 2014 Behavioral Risk Factor Surveillance System (BRFSS) as well as from the 2014 National Health Interview Survey (NHIS). In addition, the researchers analyzed clinical outcomes including time to clinical stability (TCS), length of hospital stay (LOS), and mortality, according to Dr. Bordon, an infectious disease specialist at Providence Health Center, Washington, and colleagues on behalf of the University of Louisville Pneumonia Study Group.

The researchers found an 18-fold greater incidence of community-acquired pneumonia in patients with COPD, compared with non-COPD patients.

A total of 18,246 individuals aged 40 and older with COPD were estimated to live in Louisville, Ky. The researchers found that 3,419 COPD patients were hospitalized due to CAP in Louisville during the 2-year study period. COPD patients, compared with non-COPD patients, were more likely to have a history of heart failure, more ICU admissions, and use of mechanical ventilation, compared with patients without COPD. The two groups had similar pneumonia severity index scores, and 17% received oral steroids prior to admission. COPD patients had more pneumococcal pneumonia, despite receiving pneumococcal vaccine significantly more often than non-COPD patients.

The annual incidence of hospitalized CAP was 9,369 cases per 100,000 COPD patients in the city of Louisville. In the same period, the incidence of CAP in patients without COPD was 509 per 100,000, a more than 18-fold difference.

Although the incidence of CAP in COPD patients was much higher than in those without, the difference didn’t appear to have an impact on clinical outcomes. There were no clinical differences among patients with vs. without COPD in regard to time to reach clinical improvement and time of hospital discharge, and in-hospital mortality was not statistically significantly different between the groups, the authors reported. The mortality of COPD patients during hospitalization, at 30 days, at 6 months, and at 1 year was 5.6% of patients, 11.9%, 24.3%, and 33.0%, respectively vs. 6.6%, 14.2%, 24.2%, and 30.1% in non-COPD patients. However, 1-year all-cause mortality was a significant 25% greater among COPD patients, as might be expected by the progression and effects of the underlying disease.

“[Our] observations mean that nearly 1 in 10 persons with COPD will be hospitalized annually due to CAP. This translates into approximately 500,000 COPD patients hospitalized with CAP every year in the U.S., resulting in a substantial burden of approximately 5 billion U.S. dollars in hospitalization costs,” the researchers stated.

“Modifiable factors associated with CAP such as tobacco smoking and immunizations should be health interventions to prevent the burden of CAP in COPD patients,” even though “pneumococcal vaccination was used more often in the COPD population than in other CAP patients, but pneumococcal pneumonia still occurred at a numerically higher rate,” they noted.

The study was supported by the University of Louisville, Ky., with partial support from Pfizer. The authors reported having no conflicts.
