Vision Screening, Examination, and Referral
Screen for vision concerns at every well-child visit. I recommend a consistent method of screening so you and your staff develop a skill set and yield consistent results. The screening method varies by the age and cooperation of the child, so it is useful to establish protocols for the preverbal child and for an older child who can actively participate in visual acuity testing.
The American Academy of Pediatrics has a wonderful publication with vision screening recommendations for pediatricians. The AAP's policy statement on “Eye Examination and Vision Screening in Infants, Children, and Young Adults” contains consensus-driven information of high value to pediatricians (http://tinyurl.com/3o6papp
Importantly, keep in mind that many children old enough to participate in vision testing often perform poorly on initial testing.
There is a large learning curve, and a child who performs poorly the first time will often do very well on the second test. So it's a good idea to retest before referring a child to a specialist for poor vision.
If the child is cooperative, you can retest during the same visit and save the patient a return trip to your office. If the child fails visual acuity testing twice, that is when I would refer to an eye specialist.
Pediatricians are essentially looking for reduced vision, misalignment of the eye, and any anatomic abnormalities of the eye.
More specifically, you are screening for amblyopia, which can occur in up to 4% of the population; strabismus or eye misalignment; and anatomic concerns including ptosis, abnormal size of the eye, or a white pupil that suggests a cataract or a retinoblastoma.
A positive finding on almost every aspect of screening indicates need for referral of the patient to a specialist.
In contrast, acute abnormalities such as redness of the eye, minor injuries, and allergic conjunctivitis can be managed well in your office.
Keep in mind that failure to respond to initial treatment is an indication for referral. If you treat a child for red eye, for example, and the eye does not improve quickly, referral is warranted. Importantly, it is not usually an indication to change their antibiotic drop or switch them to another treatment. Although most of the time a simple problem may be the culprit, a red eye also can signal a more serious condition.
Referral of any child who screens positive for an eye concern or fails to initially respond to treatment generally requires no additional evaluation in the primary care setting. Just send the child along with a note explaining your concern and outlining any special circumstances that might not emerge on routine history taking with the parents. We'll take it from there.
In addition to the AAP guidelines, I recommend two mnemonics to assist primary care physicians during eye evaluation. A stretched version of MVP, the MVPea mnemonic can guide assessment and ensure that a quick examination is complete:
▸ M stands for motility. Are the eyes straight and do they move normally?
▸ V is vision assessment.
▸ P is pupil assessment. Are the pupils equal, round, and reactive? Do you see an afferent defect (decreased pupillary response to light in the affected eye), or an abnormality such as a white pupil or pupillary asymmetry?
▸ e is external exam. Assess surrounding structures, including the eyelids and eyelashes, for any abnormality.
▸ a is for the anterior segment. Evaluate the cornea, the lens, and other structures.
These are the critical components of a pediatrician's regular eye examination. These steps should take you a very short amount of time.
If you have a particular interest in eye disorders and some practice and skill at ocular examinations, you can consider adding three supplementary components to your assessment. I call these the ophthalmic version of CPR for the pediatrician:
▸ C is for confrontational visual field testing.
▸ P is for pressure.
▸ R is for retina.

NHLBI Halts Niacin Study Early; No Added Reduction in CV Events
The National Heart, Lung, and Blood Institute has stopped the AIM-HIGH clinical trial 18 months earlier than planned because the addition of high-dose, extended-release niacin has not reduced the risk of cardiovascular events in patients with a history of cardiovascular disease who were taking a statin to lower LDL cholesterol.
At the time the trial was stopped, the yearly rate of cardiovascular events (fatal or nonfatal MI, strokes, hospitalization for acute coronary syndrome, or revascularization procedures) was 5.6% in the control arm and 5.8% in the niacin arm. The news comes from a telebriefing held by the NHLBI on May 26.
"Although high-dose niacin effectively raised the participants’ HDL cholesterol, it did not affect the overall rate of cardiovascular events," said Dr. Susan B. Shurin, acting director of NHLBI.
"The trial was stopped because the data showed that there was a less than 1 in 10,000 chance that the trial would ever show the expected benefit planned in the protocol on the primary outcome measure," added co–primary investigator Dr. Jeffrey Probstfield of the University of Washington, Seattle.
The investigators cautioned nonetheless that individuals who take niacin should not stop without consulting their physician. They also noted that the findings should not alter clinical practice, and should apply only to participants of the AIM-HIGH trial for now.
In late April 2011, the study’s data safety and monitoring board concluded that high-dose, extended-release niacin offered no benefits beyond statin therapy alone in reducing cardiovascular events. The board also noted a small, statistically significant but unexplained increase in ischemic stroke rates in the high-dose, extended-release niacin group.
During the 32-month follow-up period, there were 28 strokes (1.6%) among patients in the niacin group, compared with 12 strokes (0.7%) reported in the control group. In particular, roughly a third (32%) of the strokes in the niacin group occurred in participants who had discontinued the drug at least 2 months and up to 4 years earlier. This finding contributed to the NHLBI acting director’s decision to stop the trial early. Previous studies have not suggested that stroke is a potential complication of niacin. It’s unclear whether this trend seen in this study was due to chance or related to niacin administration or some other issue.
For the AIM-HIGH (Atherothrombosis Intervention in Metabolic Syndrome With Low HDL/High Triglycerides: Impact on Global Health Outcomes) trial, researchers enrolled 3,414 participants in the United States and Canada who had a history of cardiovascular disease and who were taking a statin drug to keep their LDL cholesterol levels low. Study participants also had low HDL cholesterol and high triglyceride levels, which meant that they were at significant risk of experiencing future cardiovascular events.
Niacin is known to raise HDL cholesterol and lower triglycerides. Study participants were randomly assigned to either high-dose extended-release niacin (Niaspan) in gradually increasing doses up to 2,000 mg/day (1,718 people) or a placebo treatment (1,696 people). All participants were prescribed simvastatin (Zocor), and 515 participants were given a second LDL cholesterol–lowering drug, ezetimibe (Zetia), in order to maintain LDL cholesterol levels in the target range of 40-80 mg/dL.
Importantly, this trial excluded individuals with acute coronary syndrome and recent MI or percutaneous coronary intervention. The investigators highlighted that the results of this trial apply only to patients in this specific population and can’t be extrapolated to other groups.
Earlier studies of niacin had shown more favorable results. However, the earlier studies were not designed specifically to evaluate the impact of raising HDL cholesterol on the risk of cardiovascular events while maintaining excellent LDL cholesterol control, as in the AIM-HIGH study. Several other trials testing this hypothesis – including a large international trial of high-dose, extended-release niacin – are still ongoing.
The niacin tested in the study is a proprietary formulation manufactured by Abbott Laboratories. The Food and Drug Administration regulates the use of high doses of niacin (more than 500 mg) by prescription for helping treat low HDL cholesterol and/or high triglycerides. At prescription-level doses, flushing can occur. The extended-release formulation of niacin that was tested in AIM-HIGH was intended to help reduce the likelihood of flushing.
All AIM-HIGH study participants have been informed of the results and will be followed for an additional 12-18 months. The study investigators will focus on completing data collection and analysis. The preliminary outcomes of the study are expected to be reported at scientific meetings in the fall of 2011.

Teamwork Works
Quality-improvement (QI) initiatives should be viewed through the prism of systems change, not just as one-off checklists that show some uptick against core measures, says a researcher whose work was published in the Journal of Hospital Medicine this month.
Ted Speroff, PhD, professor at the VA Tennessee Valley Healthcare System's Center for Health Services Research, led a team of researchers who found that using a collaborative approach to preventing central-line-associated bloodstream infections (CLABSI) and ventilator-associated pneumonias (VAP) worked better than simply using toolkits.
The study, "Quality Improvement Projects Targeting Healthcare-Associated Infections: Comparing Virtual Collaborative and Toolkit Approaches," found that 83% of ICUs using the collaborative approach implemented all CLABSI interventions, versus 64% of those in the toolkit group (P=0.13). The study further reported that 86% of the "collaborative group" implemented the VAP bundle, compared with 64% of the "toolkit group" (P=0.06). There was no statistically significant difference in patient outcomes.
"The key point is that quality improvement has a cultural and psychological component to it," Dr. Speroff says. "It's not just a task force of a subcommittee that you set up to achieve one tactical objective."
The study refers repeatedly to continuous quality improvement (CQI), which Dr. Speroff says HM leaders are in position to spearhead as many hospitalists already are viewed as QI leaders in their institutions.
But reform can only happen if HM and other specialties buy into the concept, and administrators don’t view it in terms of purely a cost-benefit analysis.
"There has to be a will to go that that road or some sense of urgency," Dr. Speroff says.

Patient-Safety Professionals Form Society
The National Patient Safety Foundation (NPSF) recently announced the launch of the American Society of Professionals in Patient Safety (ASPPS), a multidisciplinary membership organization designed to elevate patient safety to the level of a unique healthcare discipline. The new group has set as an early priority the development of a cross-disciplinary certification program for patient-safety professionals by 2012.
NPSF was formed in 1997 following a meeting of major health organizations to discuss patient safety, explains president Diane Pinakiewicz, MBA, who also heads ASPPS.
"When we first started, issues of medical errors and patient safety were not as widely recognized," she says.
The translation of error-prevention strategies from other fields (e.g. aviation) into healthcare continues to grow, and today there are more tools and resources to help healthcare professionals. "But they often have a hard time prioritizing it," Pinakiewicz says. "The challenge is to identify where are the biggest levers for the field and the discipline of patient safety."
Increasingly, transitions of care are being recognized as critical to safe and effective patient flow, and NPSF included a focus on preventing readmissions in its promotion of Patient Safety Awareness Week, March 6-12.
More than 300 health professionals have joined ASPPS, about 15% of them physicians, including many chief medical officers and patient safety officers, Pinakiewicz says. Although it is not known how many of these physicians are working hospitalists, "from my perspective, the hospitalist is in an incredibly pivotal seat."

Addressing Inpatient Crowding
High levels of hospital occupancy are associated with compromises to quality of care and access (often referred to as crowding), 18 while low occupancy may be inefficient and also impact quality. 9, 10 Despite this, hospitals typically have uneven occupancy. Although some demand for services is driven by factors beyond the control of a hospital (eg, seasonal variation in viral illness), approximately 15%30% of admissions to children's hospitals are scheduled from days to months in advance, with usual arrivals on weekdays. 1114 For example, of the 3.4 million elective admissions in the 2006 Healthcare Cost and Utilization Project Kids Inpatient Database (HCUP KID), only 13% were admitted on weekends. 14 Combined with short length of stay (LOS) for such patients, this leads to higher midweek and lower weekend occupancy. 12
Hospitals respond to crowding in a number of ways, but often focus on reducing LOS to make room for new patients. 11, 15, 16 For hospitals that are relatively efficient in terms of LOS, efforts to reduce it may not increase functional capacity adequately. In children's hospitals, median lengths of stay are 2 to 3 days, and one‐third of hospitalizations are 1 day or less. 17 Thus, even 10%20% reductions in LOS trims hours, not days, from typical stays. Practical barriers (eg, reluctance to discharge in the middle of the night, or family preferences and work schedules) and undesired outcomes (eg, increased hospital re‐visits) are additional pitfalls encountered by relying on throughput enhancement alone.
Managing scheduled admissions through smoothing is an alternative strategy to reduce variability and high occupancy. 6, 12, 1820 The concept is to proactively control the entry of patients, when possible, to achieve more even levels of occupancy, instead of the peaks and troughs commonly encountered. Nonetheless, it is not a widely used approach. 18, 20, 21 We hypothesized that children's hospitals had substantial unused capacity that could be used to smooth occupancy, which would reduce weekday crowding. While it is obvious that smoothing will reduce peaks to average levels (and also raise troughs), we sought to quantify just how large this difference wasand thereby quantify the potential of smoothing to reduce inpatient crowding (or, conversely, expose more patients to high levels of occupancy). Is there enough variation to justify smoothing, and, if a hospital does smooth, what is the expected result? If the number of patients removed from exposure to high occupancy is not substantial, other means to address inpatient crowding might be of more value. Our aims were to quantify the difference in weekday versus weekend occupancy, report on mathematical feasibility of such an approach, and determine the difference in number of patients exposed to various levels of high occupancy.
Methods
Data Source
This retrospective study was conducted with resource‐utilization data from 39 freestanding, tertiary‐care children's hospitals in the Pediatric Health Information System (PHIS). Participating hospitals are located in noncompeting markets of 23 states, plus the District of Columbia, and affiliated with the Child Health Corporation of America (CHCA, Shawnee Mission, KS). They account for 80% of freestanding, and 20% of all general, tertiary‐care children's hospitals. Data quality and reliability are assured through joint ongoing, systematic monitoring. The Children's Hospital of Philadelphia Committees for the Protection of Human Subjects approved the protocol with a waiver of informed consent.
Patients
Patients admitted January 1December 31, 2007 were eligible for inclusion. Due to variation in the presence of birthing, neonatal intensive care, and behavioral health units across hospitals, these beds and associated patients were excluded. Inpatients enter hospitals either as scheduled (often referred to as elective) or unscheduled (emergent or urgent) admissions. Because PHIS does not include these data, KID was used to standardize the PHIS data for proportion of scheduled admissions. 22 (KID is a healthcare database of 23 million pediatric inpatient discharges developed through federalstateindustry partnership, and sponsored by the Agency for Healthcare Research and Quality [AHRQ].) Each encounter in KID includes a principal International Classification of Diseases, 9th revision (ICD‐9) discharge diagnosis code, and is designated by the hospital as elective (ranging from chemotherapy to tonsillectomy) or not elective. Because admissions, rather than diagnoses, are scheduled, a proportion of patients with each primary diagnosis in KID are scheduled (eg, 28% of patients with a primary diagnosis of esophageal reflux). Proportions in KID were matched to principal diagnoses in PHIS.
Definitions
The census was the number of patients registered as inpatients (including those physically in the emergency department [ED] from time of ED arrival)whether observation or inpatient statusat midnight, the conclusion of the day. Hospital capacity was set using CHCA data (and confirmed by each hospital's administrative personnel) as the number of licensed in‐service beds available for patients in 2007; we assumed beds were staffed and capacity fixed for the year. Occupancy was calculated by dividing census by capacity. Maximum occupancy in a week referred to the highest occupancy level achieved in a seven‐day period (MondaySunday). We analyzed a set of thresholds for high‐occupancy (85%, 90%, 95%, and 100%), because there is no consistent definition for when hospitals are at high occupancy or when crowding occurs, though crowding has been described as starting at 85% occupancy. 2325
Analysis
The hospital was the unit of analysis. We report hospital characteristics, including capacity, number of discharges, and census region, and annual standardized length of stay ratio (SLOSR) as observed‐to‐expected LOS.
Smoothing Technique
A retrospective smoothing algorithm set each hospital's daily occupancy during a week to that hospital's mean occupancy for the week; effectively spreading the week's volume of patients evenly across the days of the week. While inter‐week and inter‐month smoothing were considered, intra‐week smoothing was deemed more practical for the largest number of patients, as it would not mean delaying care by more than one week. In the case of a planned treatment course (eg, chemotherapy), only intra‐week smoothing would maintain the necessary scheduled intervals of treatment.
Mathematical Feasibility
To approximate the number of patient admissions that would require different scheduling during a particular week to achieve smoothed weekly occupancy, we determined the total number of patient‐days in the week that required different scheduling and divided by the average LOS for the week. We then divided the number of admissions‐to‐move by total weekly admissions to compute the percentage at each hospital across 52 weeks of the year.
Measuring the Impact of Smoothing
We focused on the frequency and severity of high occupancy and the number of patients exposed to it. This framework led to 4 measures that assess the opportunity and effect of smoothing:
Difference in hospital weekdayweekend occupancy: Equal to 12‐month median of difference between mean weekday occupancy and mean weekend occupancy for each hospital‐week.
Difference in hospital maximummean occupancy: Equal to median of difference between maximum one‐day occupancy and weekly mean (smoothed) occupancy for each hospital‐week. A regression line was derived from the data for the 39 hospitals to report expected reduction in peak occupancy based on the magnitude of the difference between weekday and weekend occupancy.
Difference in number of hospitals exposed to above‐threshold occupancy: Equal to difference, pre‐ and post‐smoothing, in number of hospitals facing high‐occupancy conditions on an average of at least one weekday midnight per week during the year at different occupancy thresholds.
Difference in number of patients exposed to above‐threshold occupancy: Equal to difference, pre‐ and post‐smoothing, in number of patients exposed to hospital midnight occupancy at the thresholds. We utilized patient‐days for the calculation to avoid double‐counting, and divided this by average LOS, in order to determine the number of patients who would no longer be exposed to over‐threshold occupancy after smoothing, while also adjusting for patients newly exposed to over‐threshold occupancy levels.
All analyses were performed separately for each hospital for the entire year and then for winter (DecemberMarch), the period during which most crowding occurred. Analyses were performed using SAS (version 9.2, SAS Institute, Inc, Cary, NC); P values <0.05 were considered statistically significant.
Results
The characteristics of the 39 hospitals are provided in Table 1. Based on standardization with KID, 23.6% of PHIS admissions were scheduled (range: 18.1%35.8%) or a median of 81.5 scheduled admissions per week per hospital; 26.6% of weekday admissions were scheduled versus 16.1% for weekends. Overall, 12.4% of scheduled admissions entered on weekends. For all patients, median LOS was three days (interquartile range [IQR]: twofive days), but median LOS for scheduled admissions was two days (IQR: onefour days). The median LOS and IQR were the same by day of admission for all days of the week. Most hospitals had an overall SLOSR close to one (median: 0.9, IQR: 0.91.1). Overall, hospital mean midnight occupancy ranged from 70.9% to 108.1% on weekdays and 65.7% to 94.9% on weekends. Uniformly, weekday occupancy exceeded weekend occupancy, with a median difference of 8.2% points (IQR: 7.2%9.5% points). There was a wide range of median hospital weekdayweekend occupancy differences across hospitals (Figure 1). The overall difference was less in winter (median difference: 7.7% points; IQR: 6.3%8.8% points) than in summer (median difference: 8.6% points; IQR: 7.4%9.8% points (Wilcoxon Sign Rank test, P < 0.001). Thirty‐five hospitals (89.7%) exceeded the 85% occupancy threshold and 29 (74.4%) exceeded the 95% occupancy threshold on at least 20% of weekdays (Table 2). Across all the hospitals, the median difference in weekly maximum and weekly mean occupancy was 6.6% points (IQR: 6.2%7.4% points) (Figure 2).

Smoothing reduced the number of hospitals at each occupancy threshold, except 85% (Table 2). As a linear relationship, the reduction in weekday peak occupancy (y) based on a hospital's median difference in weekly maximum and weekly mean occupancy (x) was y = 2.69 + 0.48x. Thus, a hospital with a 10% point difference between weekday and weekend occupancy could reduce weekday peak by 7.5% points.
Smoothing increased the number of patients exposed to the lower thresholds (85% and 90%), but decreased the number of patients exposed to >95% occupancy (Table 2). For example, smoothing at the 95% threshold resulted in 630 fewer patients per hospital exposed to that threshold. If all 39 hospitals had within‐week smoothing, a net of 39,607 patients would have been protected from exposure to >95% occupancy and a net of 50,079 patients from 100% occupancy.
To demonstrate the varied effects of smoothing, Table 3 and Figure 3 present representative categories of response to smoothing depending on pre‐smoothing patterns. While not all hospitals decreased occupancy to below thresholds after smoothing (Types B and D), the overall occupancy was reduced and fewer patients were exposed to extreme levels of high occupancy (eg, >100%).
Category | Before Smoothing Hospital Description | After Smoothing Hospital Description | No. of Hospitals at 85% Threshold (n = 39) | No. of Hospitals at 95% Threshold (n = 39) |
---|---|---|---|---|
| ||||
Type A | Weekdays above threshold | All days below threshold, resulting in net decrease in patients exposed to occupancies above threshold | 3 | 1 |
Weekends below threshold | ||||
Type B | Weekdays above threshold | All days above threshold, resulting in net increase in patients exposed to occupancies above threshold | 12 | 18 |
Weekends below threshold | ||||
Type C | All days of week below threshold | All days of week below threshold | 6 | 19 |
Type D | All days of week above threshold | All days of week above threshold, resulting in net decrease in patients exposed to extreme high occupancy | 18 | 1 |

To achieve within‐week smoothing, a median of 7.4 patient‐admissions per week (range: 2.314.4) would have to be scheduled on a different day of the week. This equates to a median of 2.6% (IQR: 2.25%, 2.99%; range: 0.02%9.2%) of all admissionsor 9% of a typical hospital‐week's scheduled admissions.
Discussion
This analysis of 39 children's hospitals found high levels of occupancy and weekend occupancy lower than weekday occupancy (median difference: 8.2% points). Only 12.4% of scheduled admissions entered on weekends. Thus, weekend capacity is available to offset high weekday occupancy. Hospitals at the higher end of the occupancy thresholds (95%, 100%) would reduce the number of days operating at very high occupancy and the number of patients exposed to such levels by smoothing. This change is mathematically feasible, as a median of 7.4 patients would have to be proactively scheduled differently each week, just under one‐tenth of scheduled admissions. Since LOS by day of admission was the same (median: two days), the opportunity to affect occupancy by shifting patients should be relatively similar for all days of the week. In addition, these admissions were short, conferring greater flexibility. Implementing smoothing over the course of the week does not necessarily require admitting patients on weekends. For example, Monday admissions with an anticipated three‐day LOS could enter on Friday with anticipated discharge on Monday to alleviate midweek crowding and take advantage of unoccupied weekend beds. 26
At the highest levels of occupancy, smoothing reduces the frequency of reaching these maximum levels, but can have the effect of actually exposing more patient‐days to a higher occupancy. For example, for nine hospitals in our analysis with >20% of days over 100%, smoothing decreased days over 100%, but exposed weekend patients to higher levels of occupancy (Figure 3). Since most admissions are short and most scheduled admissions currently occur on weekdays, the number of individual patients (not patient‐days) newly exposed to such high occupancy may not increase much after smoothing at these facilities. Regardless, hospitals with such a pattern may not be able to rely solely on smoothing to avoid weekday crowding, and, if they are operating efficiently in terms of SLOSR, might be justified in building more capacity.
Consistent with our findings, the Institute for Healthcare Improvement, the Institute for Healthcare Optimization, and the American Hospital Association Quality Center stress that addressing artificial variability of scheduled admissions is a critical first step to improving patient flow and quality of care while reducing costs. 18, 21, 27 Our study suggests that small numbers of patients need to be proactively scheduled differently to decrease midweek peak occupancy, so only a small proportion of families would need to find this desirable to make it attractive for hospitals and patients. This type of proactive smoothing decreases peak occupancy on weekdays, reducing the safety risks associated with high occupancy, improving acute access for emergent patients, shortening wait‐times and loss of scheduled patients to another facility, and increasing procedure volume (3%74% in one study). 28 Smoothing may also increase quality and safety on weekends, as emergent patients admitted on weekends experience more delays in necessary treatment and have worse outcomes. 2932 In addition, increasing scheduled admissions to span weekends may appeal to some families wishing to avoid absence from work to be with their hospitalized child, to parents concerned about school performanceand may also appeal to staff members seeking flexible schedules. Increasing weekend hospital capacity is safe, feasible, and economical, even when considering the increased wages for weekend work. 33, 34 Finally, smoothing over the whole week allows fixed costs (eg, surgical suites, imaging equipment) to be allocated over 7 days rather than 5, and allows for better matching of revenue to the fixed expenses.
Rather than a prescriptive approach, our work suggests hospitals need to identify only a small number of patients to proactively shift, providing them opportunities to adapt the approach to local circumstances. The particular patients to move around may also depend on the costs and benefits of services (eg, radiologic, laboratory, operative) and the hospital's existing patterns of staffing. A number of hospitals that have engaged in similar work have achieved sustainable results, such as Seattle Children's Hospital, Boston Medical Center, St. John's Regional Health Center, and New York University Langone Medical Center. 19, 26, 3537 In these cases, proactive smoothing took advantage of unused capacity and decreased crowding on days that had been traditionally very full. Hospitals that rarely or never have high‐occupancy days, and that do not expect growth in volume, may not need to employ smoothing, whereas others that have crowding issues primarily in the winter may wish to implement smoothing techniques seasonally.
Aside from attempting to reduce high‐occupancy through modification of admission patterns, other proactive approaches include optimizing staffing and processes around care, improving efficiency of care, and building additional beds. 16, 25, 38, 39 However, the expense of construction and the scarcity of capital often preclude this last option. Among children's hospitals, with SLOSR close to one, implementing strategies to reduce the LOS during periods of high occupancy may not result in meaningful reductions in LOS, as such approaches would only decrease the typical child's hospitalization by hours, not days. In addition to proactive strategies, hospitals also rely on reactive approaches, such as ED boarding, placing patients in hallways on units, diverting ambulances or transfers, or canceling scheduled admissions at the last moment, to decrease crowding. 16, 39, 40
This study has several limitations. First, use of administrative data precluded modeling all responses. For example, some hospitals may be better able to accommodate fluctuations in census or high occupancy without compromising quality or access. Second, we only considered intra‐week smoothing, but hospitals may benefit from smoothing over longer periods of time, especially since children's hospitals are busier in winter months, but incoming scheduled volume is often not reduced. 11 Hospitals with large occupancy variations across months may want to consider broadening the time horizon for smoothing, and weigh the costs and benefits over that period of time, including parental and clinician concerns and preferences for not delaying treatment. At the individual hospital level, discrete‐event simulation would likely be useful to consider the trade‐offs of smoothing to different levels and over different periods of time. Third, we assumed a fixed number of beds for the year, an approach that may not accurately reflect actual available beds on specific days. This limitation was minimized by counting all beds for each hospital as available for all the days of the year, so that hospitals with a high census when all available beds are included would have an even higher percent occupancy if some of those beds were not actually open. In a related way, then, we also do not consider how staffing may need to be altered or augmented to care for additional patients on certain days. Fourth, midnight census, the only universally available measure, was used to determine occupancy rather than peak census. Midnight census provides a standard snapshot, but is lower than mid‐day peak census. 41 In order to account for these limitations, we considered several different thresholds of high occupancy. Fifth, we smoothed at the hospital level, but differential effects may exist at the unit level. Sixth, to determine proportion of scheduled admissions, we used HCUP KID proportions on PHIS admissions. Overall, this approach likely overestimated scheduled medical admissions on weekends, thus biasing our result towards the null hypothesis. Finally, only freestanding children's hospitals were included in this study. While this may limit generalizability, the general concept of smoothing occupancy should apply in any setting with substantial and consistent variation.
In summary, our study revealed that children's hospitals often face high midweek occupancy, but also have substantial unused weekend capacity. Hospitals facing challenges with high weekday occupancy could proactively use a smoothing approach to decrease the frequency and severity of high occupancy. Further qualitative evaluation is also warranted around child, family, and staff preferences concerning scheduled admissions, school, and work.

High levels of hospital occupancy are associated with compromises to quality of care and access (often referred to as crowding), 18 while low occupancy may be inefficient and also impact quality. 9, 10 Despite this, hospitals typically have uneven occupancy. Although some demand for services is driven by factors beyond the control of a hospital (eg, seasonal variation in viral illness), approximately 15%30% of admissions to children's hospitals are scheduled from days to months in advance, with usual arrivals on weekdays. 1114 For example, of the 3.4 million elective admissions in the 2006 Healthcare Cost and Utilization Project Kids Inpatient Database (HCUP KID), only 13% were admitted on weekends. 14 Combined with short length of stay (LOS) for such patients, this leads to higher midweek and lower weekend occupancy. 12
Hospitals respond to crowding in a number of ways, but often focus on reducing LOS to make room for new patients. 11, 15, 16 For hospitals that are relatively efficient in terms of LOS, efforts to reduce it may not increase functional capacity adequately. In children's hospitals, median lengths of stay are 2 to 3 days, and one‐third of hospitalizations are 1 day or less. 17 Thus, even 10%20% reductions in LOS trims hours, not days, from typical stays. Practical barriers (eg, reluctance to discharge in the middle of the night, or family preferences and work schedules) and undesired outcomes (eg, increased hospital re‐visits) are additional pitfalls encountered by relying on throughput enhancement alone.
Managing scheduled admissions through smoothing is an alternative strategy to reduce variability and high occupancy. 6, 12, 1820 The concept is to proactively control the entry of patients, when possible, to achieve more even levels of occupancy, instead of the peaks and troughs commonly encountered. Nonetheless, it is not a widely used approach. 18, 20, 21 We hypothesized that children's hospitals had substantial unused capacity that could be used to smooth occupancy, which would reduce weekday crowding. While it is obvious that smoothing will reduce peaks to average levels (and also raise troughs), we sought to quantify just how large this difference wasand thereby quantify the potential of smoothing to reduce inpatient crowding (or, conversely, expose more patients to high levels of occupancy). Is there enough variation to justify smoothing, and, if a hospital does smooth, what is the expected result? If the number of patients removed from exposure to high occupancy is not substantial, other means to address inpatient crowding might be of more value. Our aims were to quantify the difference in weekday versus weekend occupancy, report on mathematical feasibility of such an approach, and determine the difference in number of patients exposed to various levels of high occupancy.
Methods
Data Source
This retrospective study was conducted with resource‐utilization data from 39 freestanding, tertiary‐care children's hospitals in the Pediatric Health Information System (PHIS). Participating hospitals are located in noncompeting markets of 23 states, plus the District of Columbia, and affiliated with the Child Health Corporation of America (CHCA, Shawnee Mission, KS). They account for 80% of freestanding, and 20% of all general, tertiary‐care children's hospitals. Data quality and reliability are assured through joint ongoing, systematic monitoring. The Children's Hospital of Philadelphia Committees for the Protection of Human Subjects approved the protocol with a waiver of informed consent.
Patients
Patients admitted January 1December 31, 2007 were eligible for inclusion. Due to variation in the presence of birthing, neonatal intensive care, and behavioral health units across hospitals, these beds and associated patients were excluded. Inpatients enter hospitals either as scheduled (often referred to as elective) or unscheduled (emergent or urgent) admissions. Because PHIS does not include these data, KID was used to standardize the PHIS data for proportion of scheduled admissions. 22 (KID is a healthcare database of 23 million pediatric inpatient discharges developed through federalstateindustry partnership, and sponsored by the Agency for Healthcare Research and Quality [AHRQ].) Each encounter in KID includes a principal International Classification of Diseases, 9th revision (ICD‐9) discharge diagnosis code, and is designated by the hospital as elective (ranging from chemotherapy to tonsillectomy) or not elective. Because admissions, rather than diagnoses, are scheduled, a proportion of patients with each primary diagnosis in KID are scheduled (eg, 28% of patients with a primary diagnosis of esophageal reflux). Proportions in KID were matched to principal diagnoses in PHIS.
Definitions
The census was the number of patients registered as inpatients (including those physically in the emergency department [ED] from time of ED arrival)whether observation or inpatient statusat midnight, the conclusion of the day. Hospital capacity was set using CHCA data (and confirmed by each hospital's administrative personnel) as the number of licensed in‐service beds available for patients in 2007; we assumed beds were staffed and capacity fixed for the year. Occupancy was calculated by dividing census by capacity. Maximum occupancy in a week referred to the highest occupancy level achieved in a seven‐day period (MondaySunday). We analyzed a set of thresholds for high‐occupancy (85%, 90%, 95%, and 100%), because there is no consistent definition for when hospitals are at high occupancy or when crowding occurs, though crowding has been described as starting at 85% occupancy. 2325
Analysis
The hospital was the unit of analysis. We report hospital characteristics, including capacity, number of discharges, and census region, and annual standardized length of stay ratio (SLOSR) as observed‐to‐expected LOS.
Smoothing Technique
A retrospective smoothing algorithm set each hospital's daily occupancy during a week to that hospital's mean occupancy for the week; effectively spreading the week's volume of patients evenly across the days of the week. While inter‐week and inter‐month smoothing were considered, intra‐week smoothing was deemed more practical for the largest number of patients, as it would not mean delaying care by more than one week. In the case of a planned treatment course (eg, chemotherapy), only intra‐week smoothing would maintain the necessary scheduled intervals of treatment.
Mathematical Feasibility
To approximate the number of patient admissions that would require different scheduling during a particular week to achieve smoothed weekly occupancy, we determined the total number of patient‐days in the week that required different scheduling and divided by the average LOS for the week. We then divided the number of admissions‐to‐move by total weekly admissions to compute the percentage at each hospital across 52 weeks of the year.
Measuring the Impact of Smoothing
We focused on the frequency and severity of high occupancy and the number of patients exposed to it. This framework led to 4 measures that assess the opportunity and effect of smoothing:
Difference in hospital weekdayweekend occupancy: Equal to 12‐month median of difference between mean weekday occupancy and mean weekend occupancy for each hospital‐week.
Difference in hospital maximummean occupancy: Equal to median of difference between maximum one‐day occupancy and weekly mean (smoothed) occupancy for each hospital‐week. A regression line was derived from the data for the 39 hospitals to report expected reduction in peak occupancy based on the magnitude of the difference between weekday and weekend occupancy.
Difference in number of hospitals exposed to above‐threshold occupancy: Equal to difference, pre‐ and post‐smoothing, in number of hospitals facing high‐occupancy conditions on an average of at least one weekday midnight per week during the year at different occupancy thresholds.
Difference in number of patients exposed to above‐threshold occupancy: Equal to difference, pre‐ and post‐smoothing, in number of patients exposed to hospital midnight occupancy at the thresholds. We utilized patient‐days for the calculation to avoid double‐counting, and divided this by average LOS, in order to determine the number of patients who would no longer be exposed to over‐threshold occupancy after smoothing, while also adjusting for patients newly exposed to over‐threshold occupancy levels.
All analyses were performed separately for each hospital for the entire year and then for winter (DecemberMarch), the period during which most crowding occurred. Analyses were performed using SAS (version 9.2, SAS Institute, Inc, Cary, NC); P values <0.05 were considered statistically significant.
Results
The characteristics of the 39 hospitals are provided in Table 1. Based on standardization with KID, 23.6% of PHIS admissions were scheduled (range: 18.1%35.8%) or a median of 81.5 scheduled admissions per week per hospital; 26.6% of weekday admissions were scheduled versus 16.1% for weekends. Overall, 12.4% of scheduled admissions entered on weekends. For all patients, median LOS was three days (interquartile range [IQR]: twofive days), but median LOS for scheduled admissions was two days (IQR: onefour days). The median LOS and IQR were the same by day of admission for all days of the week. Most hospitals had an overall SLOSR close to one (median: 0.9, IQR: 0.91.1). Overall, hospital mean midnight occupancy ranged from 70.9% to 108.1% on weekdays and 65.7% to 94.9% on weekends. Uniformly, weekday occupancy exceeded weekend occupancy, with a median difference of 8.2% points (IQR: 7.2%9.5% points). There was a wide range of median hospital weekdayweekend occupancy differences across hospitals (Figure 1). The overall difference was less in winter (median difference: 7.7% points; IQR: 6.3%8.8% points) than in summer (median difference: 8.6% points; IQR: 7.4%9.8% points (Wilcoxon Sign Rank test, P < 0.001). Thirty‐five hospitals (89.7%) exceeded the 85% occupancy threshold and 29 (74.4%) exceeded the 95% occupancy threshold on at least 20% of weekdays (Table 2). Across all the hospitals, the median difference in weekly maximum and weekly mean occupancy was 6.6% points (IQR: 6.2%7.4% points) (Figure 2).

Smoothing reduced the number of hospitals at each occupancy threshold, except 85% (Table 2). As a linear relationship, the reduction in weekday peak occupancy (y) based on a hospital's median difference in weekly maximum and weekly mean occupancy (x) was y = 2.69 + 0.48x. Thus, a hospital with a 10% point difference between weekday and weekend occupancy could reduce weekday peak by 7.5% points.
Smoothing increased the number of patients exposed to the lower thresholds (85% and 90%), but decreased the number of patients exposed to >95% occupancy (Table 2). For example, smoothing at the 95% threshold resulted in 630 fewer patients per hospital exposed to that threshold. If all 39 hospitals had within‐week smoothing, a net of 39,607 patients would have been protected from exposure to >95% occupancy and a net of 50,079 patients from 100% occupancy.
To demonstrate the varied effects of smoothing, Table 3 and Figure 3 present representative categories of response to smoothing depending on pre‐smoothing patterns. While not all hospitals decreased occupancy to below thresholds after smoothing (Types B and D), the overall occupancy was reduced and fewer patients were exposed to extreme levels of high occupancy (eg, >100%).

To achieve within‐week smoothing, a median of 7.4 patient‐admissions per week (range: 2.314.4) would have to be scheduled on a different day of the week. This equates to a median of 2.6% (IQR: 2.25%, 2.99%; range: 0.02%9.2%) of all admissionsor 9% of a typical hospital‐week's scheduled admissions.
Discussion
This analysis of 39 children's hospitals found high levels of occupancy and weekend occupancy lower than weekday occupancy (median difference: 8.2% points). Only 12.4% of scheduled admissions entered on weekends. Thus, weekend capacity is available to offset high weekday occupancy. Hospitals at the higher end of the occupancy thresholds (95%, 100%) would reduce the number of days operating at very high occupancy and the number of patients exposed to such levels by smoothing. This change is mathematically feasible, as a median of 7.4 patients would have to be proactively scheduled differently each week, just under one‐tenth of scheduled admissions. Since LOS by day of admission was the same (median: two days), the opportunity to affect occupancy by shifting patients should be relatively similar for all days of the week. In addition, these admissions were short, conferring greater flexibility. Implementing smoothing over the course of the week does not necessarily require admitting patients on weekends. For example, Monday admissions with an anticipated three‐day LOS could enter on Friday with anticipated discharge on Monday to alleviate midweek crowding and take advantage of unoccupied weekend beds. 26
At the highest levels of occupancy, smoothing reduces the frequency of reaching these maximum levels, but can have the effect of actually exposing more patient‐days to a higher occupancy. For example, for nine hospitals in our analysis with >20% of days over 100%, smoothing decreased days over 100%, but exposed weekend patients to higher levels of occupancy (Figure 3). Since most admissions are short and most scheduled admissions currently occur on weekdays, the number of individual patients (not patient‐days) newly exposed to such high occupancy may not increase much after smoothing at these facilities. Regardless, hospitals with such a pattern may not be able to rely solely on smoothing to avoid weekday crowding, and, if they are operating efficiently in terms of SLOSR, might be justified in building more capacity.
Consistent with our findings, the Institute for Healthcare Improvement, the Institute for Healthcare Optimization, and the American Hospital Association Quality Center stress that addressing artificial variability of scheduled admissions is a critical first step to improving patient flow and quality of care while reducing costs. 18, 21, 27 Our study suggests that small numbers of patients need to be proactively scheduled differently to decrease midweek peak occupancy, so only a small proportion of families would need to find this desirable to make it attractive for hospitals and patients. This type of proactive smoothing decreases peak occupancy on weekdays, reducing the safety risks associated with high occupancy, improving acute access for emergent patients, shortening wait‐times and loss of scheduled patients to another facility, and increasing procedure volume (3%74% in one study). 28 Smoothing may also increase quality and safety on weekends, as emergent patients admitted on weekends experience more delays in necessary treatment and have worse outcomes. 2932 In addition, increasing scheduled admissions to span weekends may appeal to some families wishing to avoid absence from work to be with their hospitalized child, to parents concerned about school performanceand may also appeal to staff members seeking flexible schedules. Increasing weekend hospital capacity is safe, feasible, and economical, even when considering the increased wages for weekend work. 33, 34 Finally, smoothing over the whole week allows fixed costs (eg, surgical suites, imaging equipment) to be allocated over 7 days rather than 5, and allows for better matching of revenue to the fixed expenses.
Rather than a prescriptive approach, our work suggests hospitals need to identify only a small number of patients to proactively shift, providing them opportunities to adapt the approach to local circumstances. The particular patients to move around may also depend on the costs and benefits of services (eg, radiologic, laboratory, operative) and the hospital's existing patterns of staffing. A number of hospitals that have engaged in similar work have achieved sustainable results, such as Seattle Children's Hospital, Boston Medical Center, St. John's Regional Health Center, and New York University Langone Medical Center. 19, 26, 3537 In these cases, proactive smoothing took advantage of unused capacity and decreased crowding on days that had been traditionally very full. Hospitals that rarely or never have high‐occupancy days, and that do not expect growth in volume, may not need to employ smoothing, whereas others that have crowding issues primarily in the winter may wish to implement smoothing techniques seasonally.
Aside from attempting to reduce high‐occupancy through modification of admission patterns, other proactive approaches include optimizing staffing and processes around care, improving efficiency of care, and building additional beds. 16, 25, 38, 39 However, the expense of construction and the scarcity of capital often preclude this last option. Among children's hospitals, with SLOSR close to one, implementing strategies to reduce the LOS during periods of high occupancy may not result in meaningful reductions in LOS, as such approaches would only decrease the typical child's hospitalization by hours, not days. In addition to proactive strategies, hospitals also rely on reactive approaches, such as ED boarding, placing patients in hallways on units, diverting ambulances or transfers, or canceling scheduled admissions at the last moment, to decrease crowding. 16, 39, 40
This study has several limitations. First, use of administrative data precluded modeling all responses. For example, some hospitals may be better able to accommodate fluctuations in census or high occupancy without compromising quality or access. Second, we only considered intra‐week smoothing, but hospitals may benefit from smoothing over longer periods of time, especially since children's hospitals are busier in winter months, but incoming scheduled volume is often not reduced. 11 Hospitals with large occupancy variations across months may want to consider broadening the time horizon for smoothing, and weigh the costs and benefits over that period of time, including parental and clinician concerns and preferences for not delaying treatment. At the individual hospital level, discrete‐event simulation would likely be useful to consider the trade‐offs of smoothing to different levels and over different periods of time. Third, we assumed a fixed number of beds for the year, an approach that may not accurately reflect actual available beds on specific days. This limitation was minimized by counting all beds for each hospital as available for all the days of the year, so that hospitals with a high census when all available beds are included would have an even higher percent occupancy if some of those beds were not actually open. In a related way, then, we also do not consider how staffing may need to be altered or augmented to care for additional patients on certain days. Fourth, midnight census, the only universally available measure, was used to determine occupancy rather than peak census. Midnight census provides a standard snapshot, but is lower than mid‐day peak census. 41 In order to account for these limitations, we considered several different thresholds of high occupancy. Fifth, we smoothed at the hospital level, but differential effects may exist at the unit level. Sixth, to determine proportion of scheduled admissions, we used HCUP KID proportions on PHIS admissions. Overall, this approach likely overestimated scheduled medical admissions on weekends, thus biasing our result towards the null hypothesis. Finally, only freestanding children's hospitals were included in this study. While this may limit generalizability, the general concept of smoothing occupancy should apply in any setting with substantial and consistent variation.
In summary, our study revealed that children's hospitals often face high midweek occupancy, but also have substantial unused weekend capacity. Hospitals facing challenges with high weekday occupancy could proactively use a smoothing approach to decrease the frequency and severity of high occupancy. Further qualitative evaluation is also warranted around child, family, and staff preferences concerning scheduled admissions, school, and work.
High levels of hospital occupancy are associated with compromises to quality of care and access (often referred to as crowding), 18 while low occupancy may be inefficient and also impact quality. 9, 10 Despite this, hospitals typically have uneven occupancy. Although some demand for services is driven by factors beyond the control of a hospital (eg, seasonal variation in viral illness), approximately 15%30% of admissions to children's hospitals are scheduled from days to months in advance, with usual arrivals on weekdays. 1114 For example, of the 3.4 million elective admissions in the 2006 Healthcare Cost and Utilization Project Kids Inpatient Database (HCUP KID), only 13% were admitted on weekends. 14 Combined with short length of stay (LOS) for such patients, this leads to higher midweek and lower weekend occupancy. 12
Hospitals respond to crowding in a number of ways, but often focus on reducing LOS to make room for new patients. 11, 15, 16 For hospitals that are relatively efficient in terms of LOS, efforts to reduce it may not increase functional capacity adequately. In children's hospitals, median lengths of stay are 2 to 3 days, and one‐third of hospitalizations are 1 day or less. 17 Thus, even 10%20% reductions in LOS trims hours, not days, from typical stays. Practical barriers (eg, reluctance to discharge in the middle of the night, or family preferences and work schedules) and undesired outcomes (eg, increased hospital re‐visits) are additional pitfalls encountered by relying on throughput enhancement alone.
Managing scheduled admissions through smoothing is an alternative strategy to reduce variability and high occupancy. 6, 12, 1820 The concept is to proactively control the entry of patients, when possible, to achieve more even levels of occupancy, instead of the peaks and troughs commonly encountered. Nonetheless, it is not a widely used approach. 18, 20, 21 We hypothesized that children's hospitals had substantial unused capacity that could be used to smooth occupancy, which would reduce weekday crowding. While it is obvious that smoothing will reduce peaks to average levels (and also raise troughs), we sought to quantify just how large this difference wasand thereby quantify the potential of smoothing to reduce inpatient crowding (or, conversely, expose more patients to high levels of occupancy). Is there enough variation to justify smoothing, and, if a hospital does smooth, what is the expected result? If the number of patients removed from exposure to high occupancy is not substantial, other means to address inpatient crowding might be of more value. Our aims were to quantify the difference in weekday versus weekend occupancy, report on mathematical feasibility of such an approach, and determine the difference in number of patients exposed to various levels of high occupancy.
Methods
Data Source
This retrospective study was conducted with resource‐utilization data from 39 freestanding, tertiary‐care children's hospitals in the Pediatric Health Information System (PHIS). Participating hospitals are located in noncompeting markets of 23 states, plus the District of Columbia, and affiliated with the Child Health Corporation of America (CHCA, Shawnee Mission, KS). They account for 80% of freestanding, and 20% of all general, tertiary‐care children's hospitals. Data quality and reliability are assured through joint ongoing, systematic monitoring. The Children's Hospital of Philadelphia Committees for the Protection of Human Subjects approved the protocol with a waiver of informed consent.
Patients
Patients admitted January 1December 31, 2007 were eligible for inclusion. Due to variation in the presence of birthing, neonatal intensive care, and behavioral health units across hospitals, these beds and associated patients were excluded.

To achieve within‐week smoothing, a median of 7.4 patient‐admissions per week (range: 2.314.4) would have to be scheduled on a different day of the week. This equates to a median of 2.6% (IQR: 2.25%, 2.99%; range: 0.02%9.2%) of all admissionsor 9% of a typical hospital‐week's scheduled admissions.
Discussion
This analysis of 39 children's hospitals found high levels of occupancy and weekend occupancy lower than weekday occupancy (median difference: 8.2% points). Only 12.4% of scheduled admissions entered on weekends. Thus, weekend capacity is available to offset high weekday occupancy. Hospitals at the higher end of the occupancy thresholds (95%, 100%) would reduce the number of days operating at very high occupancy and the number of patients exposed to such levels by smoothing. This change is mathematically feasible, as a median of 7.4 patients would have to be proactively scheduled differently each week, just under one‐tenth of scheduled admissions. Since LOS by day of admission was the same (median: two days), the opportunity to affect occupancy by shifting patients should be relatively similar for all days of the week. In addition, these admissions were short, conferring greater flexibility. Implementing smoothing over the course of the week does not necessarily require admitting patients on weekends. For example, Monday admissions with an anticipated three‐day LOS could enter on Friday with anticipated discharge on Monday to alleviate midweek crowding and take advantage of unoccupied weekend beds. 26
At the highest levels of occupancy, smoothing reduces the frequency of reaching these maximum levels, but can have the effect of actually exposing more patient‐days to a higher occupancy. For example, for nine hospitals in our analysis with >20% of days over 100%, smoothing decreased days over 100%, but exposed weekend patients to higher levels of occupancy (Figure 3). Since most admissions are short and most scheduled admissions currently occur on weekdays, the number of individual patients (not patient‐days) newly exposed to such high occupancy may not increase much after smoothing at these facilities. Regardless, hospitals with such a pattern may not be able to rely solely on smoothing to avoid weekday crowding, and, if they are operating efficiently in terms of SLOSR, might be justified in building more capacity.
Consistent with our findings, the Institute for Healthcare Improvement, the Institute for Healthcare Optimization, and the American Hospital Association Quality Center stress that addressing artificial variability of scheduled admissions is a critical first step to improving patient flow and quality of care while reducing costs. 18, 21, 27 Our study suggests that small numbers of patients need to be proactively scheduled differently to decrease midweek peak occupancy, so only a small proportion of families would need to find this desirable to make it attractive for hospitals and patients. This type of proactive smoothing decreases peak occupancy on weekdays, reducing the safety risks associated with high occupancy, improving acute access for emergent patients, shortening wait‐times and loss of scheduled patients to another facility, and increasing procedure volume (3%74% in one study). 28 Smoothing may also increase quality and safety on weekends, as emergent patients admitted on weekends experience more delays in necessary treatment and have worse outcomes. 2932 In addition, increasing scheduled admissions to span weekends may appeal to some families wishing to avoid absence from work to be with their hospitalized child, to parents concerned about school performanceand may also appeal to staff members seeking flexible schedules. Increasing weekend hospital capacity is safe, feasible, and economical, even when considering the increased wages for weekend work. 33, 34 Finally, smoothing over the whole week allows fixed costs (eg, surgical suites, imaging equipment) to be allocated over 7 days rather than 5, and allows for better matching of revenue to the fixed expenses.
Rather than a prescriptive approach, our work suggests hospitals need to identify only a small number of patients to proactively shift, providing them opportunities to adapt the approach to local circumstances. The particular patients to move around may also depend on the costs and benefits of services (eg, radiologic, laboratory, operative) and the hospital's existing patterns of staffing. A number of hospitals that have engaged in similar work have achieved sustainable results, such as Seattle Children's Hospital, Boston Medical Center, St. John's Regional Health Center, and New York University Langone Medical Center. 19, 26, 3537 In these cases, proactive smoothing took advantage of unused capacity and decreased crowding on days that had been traditionally very full. Hospitals that rarely or never have high‐occupancy days, and that do not expect growth in volume, may not need to employ smoothing, whereas others that have crowding issues primarily in the winter may wish to implement smoothing techniques seasonally.
Aside from attempting to reduce high‐occupancy through modification of admission patterns, other proactive approaches include optimizing staffing and processes around care, improving efficiency of care, and building additional beds. 16, 25, 38, 39 However, the expense of construction and the scarcity of capital often preclude this last option. Among children's hospitals, with SLOSR close to one, implementing strategies to reduce the LOS during periods of high occupancy may not result in meaningful reductions in LOS, as such approaches would only decrease the typical child's hospitalization by hours, not days. In addition to proactive strategies, hospitals also rely on reactive approaches, such as ED boarding, placing patients in hallways on units, diverting ambulances or transfers, or canceling scheduled admissions at the last moment, to decrease crowding. 16, 39, 40
This study has several limitations. First, use of administrative data precluded modeling all responses. For example, some hospitals may be better able to accommodate fluctuations in census or high occupancy without compromising quality or access. Second, we only considered intra‐week smoothing, but hospitals may benefit from smoothing over longer periods of time, especially since children's hospitals are busier in winter months, but incoming scheduled volume is often not reduced. 11 Hospitals with large occupancy variations across months may want to consider broadening the time horizon for smoothing, and weigh the costs and benefits over that period of time, including parental and clinician concerns and preferences for not delaying treatment. At the individual hospital level, discrete‐event simulation would likely be useful to consider the trade‐offs of smoothing to different levels and over different periods of time. Third, we assumed a fixed number of beds for the year, an approach that may not accurately reflect actual available beds on specific days. This limitation was minimized by counting all beds for each hospital as available for all the days of the year, so that hospitals with a high census when all available beds are included would have an even higher percent occupancy if some of those beds were not actually open. In a related way, then, we also do not consider how staffing may need to be altered or augmented to care for additional patients on certain days. Fourth, midnight census, the only universally available measure, was used to determine occupancy rather than peak census. Midnight census provides a standard snapshot, but is lower than mid‐day peak census. 41 In order to account for these limitations, we considered several different thresholds of high occupancy. Fifth, we smoothed at the hospital level, but differential effects may exist at the unit level. Sixth, to determine proportion of scheduled admissions, we used HCUP KID proportions on PHIS admissions. Overall, this approach likely overestimated scheduled medical admissions on weekends, thus biasing our result towards the null hypothesis. Finally, only freestanding children's hospitals were included in this study. While this may limit generalizability, the general concept of smoothing occupancy should apply in any setting with substantial and consistent variation.
In summary, our study revealed that children's hospitals often face high midweek occupancy, but also have substantial unused weekend capacity. Hospitals facing challenges with high weekday occupancy could proactively use a smoothing approach to decrease the frequency and severity of high occupancy. Further qualitative evaluation is also warranted around child, family, and staff preferences concerning scheduled admissions, school, and work.

CCSVI Controversy: A Call for New Research
Multiple sclerosis patients and endovascular interventionalists were elated when Italian researchers reported in 2009 that they had found evidence of chronic cerebrospinal venous insufficiency in nearly every MS patient they had studied and that in many cases, balloon angioplasty and sometimes stent placement of central thoracic veins reduced or eliminated signs of the disease. Neurologists, on the other hand, suggested that hope might be eclipsing reason in the rush to advocate the vascular procedure, given the single-center study's small sample size and nonrandomized, uncontrolled design.
The opposing perspectives incited an apparent turf war within the MS community fueled by accusations on both sides, according to Dr. Jack Burks, chief medical officer of the Multiple Sclerosis Association of America. At issue, he said, is the validity not only of the study results but also of the underlying hypothesis that toxic iron overload in the brain due to chronic cerebrospinal venous insufficiency (CCSVI) might have a primary role in the pathogenesis of MS - a hypothesis that contradicts the compelling body of evidence suggesting that MS is primarily an autoimmune condition.
On one side of the debate are the MS patients and endovascular interventionalists, dubbed the "liberators" by Dr. Burks because of their unflappable advocacy for what has become known as the liberation procedure - the endovascular surgery designed to open the lesions causing the venous insufficiency, he said.
"Neurologists believe the interventionalists are overstating the possible value of CCSVI and that commercial interests are overriding scientific inquiry," according to Dr. Burks, a neurologist and clinical professor of medicine at the University of Nevada, Reno. Patients, armed with anecdotal evidence downloaded from the Internet, are certain that CCSVI surgery is the miracle they've been waiting for and perceive the hesitancy of U.S. and Canadian neurologists to embrace the treatment as evidence of a possible conspiracy with pharmaceutical companies who stand to lose billions of dollars if the surgery becomes a first-line treatment, he said. Further, he noted, advocates of CCSVI claim that neurologists who refuse patients' demands for diagnostic testing and surgical referral for CCSVI are jeopardizing the safety of those patients, who are traveling to foreign countries to get the care that they cannot receive in North America.
To date, the majority of the evidence regarding CCSVI diagnosis and treatment in MS is inconsistent, and can be confusing, Dr. Burks noted. In the initial study, Dr. Paolo Zamboni of the University of Ferrara in Italy, and colleagues, used Doppler ultrasound to examine venous drainage of the brain and spinal cord in 65 patients with different types of MS and 235 controls without MS and observed abnormal venous flow in all of the MS patients and none of the controls. The patterns of venous obstruction differed depending on MS stage and course, although there was no apparent relationship between disease severity and extent of venous obstruction, and MS treatment status did not influence the signs of CCSVI in any of the patients, the authors wrote (J. Neurol. Neurosurg. Psychiatry 2009;80:392-9).
The researchers went on to conduct an open pilot study to determine whether percutaneous transluminal angioplasty could safely and effectively treat the narrowing of the extracranial cerebrospinal veins in the 65 MS patients in which the condition was observed - 35 with relapsing-remitting MS, 20 with secondary progressive MS, and 10 with primary progressive MS. They reported significant improvements in MS clinical outcome measures, significant reductions in new brain lesions on MRI, and significant reductions in the number of relapses experienced by some of the patients.
The findings were limited, however, not only by the study design, but also by the fact that patients remained on their disease-modifying antirheumatic drug therapy during the study period and the timing and type of MRI scans varied among the patients, according to the authors. They also noted that restenosis of the internal jugular veins occurred in nearly half of the patients (J. Vasc. Surg. 2009;50:1348-58).
Since the initial paper, a number of CCSVI studies of various designs have been undertaken, with contradictory results. Following are some of the investigations reported within the past year:
P Researchers at the University of Buffalo found that up to 62% of the 280 patients with MS enrolled in the Combined Transcranial and Extracranial Venous Doppler Evaluation study - the first randomized clinical trial to evaluate MS patients for CCSVI - had the characteristic narrowing of the extracranial veins compared with approximately 22% of 220 healthy controls. While the results, which were reported at the annual meeting of the American Academy of Neurology, did not establish causation, they showed "that narrowing of the extracranial veins, at the very least, is an important association in multiple sclerosis," principal investigator Dr. Robert Zivadinov said in a statement. He acknowledged that the finding of vascular narrowing in nearly a quarter of the healthy controls warranted additional investigation (www.buffalo.edu/news/fast-execute.cgi/article-page.html?article=109370009).
P In an open-label study of extracranial Doppler criteria of CCSVI in 70 MS patients in Poland - 49 with relapsing-remitting MS, 5 with primary progressive MS, and 16 with secondary progressive MS - investigators detected at least two of four extracranial criteria in 90% of the patients. They concluded that, while the extracranial abnormalities could exist in various combinations, "the most common pathology in our patients was the presence of an inverted valve or another pathologic structure [like membranaceous or netlike septum] in the area of junction of the [internal jugular vein] with the brachiocephalic vein (Int. Angiol. 2010;29:109-14).
P A comparison of the internal jugular vein hemodynamics and morphology in 25 patients with MS and 25 controls identified abnormal findings in 92% of the MS patients and 24% of the controls, and evidence of CCSVI in 84% of the MS patients and none of the controls, leading the investigators to conclude that both hemodynamic abnormalities and morphologic changes in the internal jugular vein "are strongly associated with MS" (Int. Angiol. 2010;29:115-20).
P An extended extra- and transcranial color-coded sonography study in 56 MS patients and 20 controls detected no internal jugular vein stenosis and normal blood flow direction in all but 1 patient. There were no between-group differences in intracranial veins and during Valsalva maneuver, and none of the patients fulfilled more than one CCSVI criterion, according to the authors. They concluded that their findings "challenge the hypothesis that cerebral venous congestion plays a significant role in the pathogenesis of MS" (Ann. Neurol. 2010;68:173-83).
P Swedish investigators used phase-contrast MRI to study 21 relapsing-remitting MS patients and 20 healthy controls and found no differences in internal jugular venous outflow, aqueductal cerebrospinal fluid flow, or the presence of internal jugular blood reflux between the two groups. Although contrast-enhanced MR angiography showed internal jugular vein stenosis in 3 of the 21 MS patients, the authors stated they found no evidence "confirming the suggested vascular multiple sclerosis hypothesis" (Ann. Neurol. 2010;68:255-9).
P The authors of an MR venography and flow quantification study in The Netherlands compared the intracranial and extracranial venous anatomy and the intracerebral venous flow profiles of 20 MS patients and 20 age- and gender-matched controls, with image analysis performed by blinded interventional neuroradiologists. They identified venous system anomalies in 50% of the MS patients and 40% of the healthy controls and no venous backflow in either group. "Given the normal intracranial venous flow quantification results, it is likely that these findings reflect anatomical variants of venous drainage rather than clinically relevant venous outflow obstructions," the authors wrote (J. Neurol. Neurosurg. Psychiatry 2010 Oct. 27 [doi: 10.1136/jnnp.2010.223479]).
P Italian researchers investigating the occurrence of CCSVI in 50 consecutive patients with clinically isolated syndromes suggestive of MS reviewed the patients' extracranial and transcranial venous echo-color Doppler sonographs and compared the findings to those of 50 age- and gender-matched healthy controls as well as those of 60 patients with transient global amnesia (TGA) and 60 healthy controls matched to the TGA patients. They found extracranial Doppler sonographic abnormalities in 52% of patients with possible MS, 68.3% of patients with TGA, and 31.8% of the healthy controls. While eight of the patients with possible MS fulfilled the CCSVI criteria, selective phlebography showed no venous anomalies in seven of them. The authors concluded that there was no evidence of CCSVI at MS onset but recommended further studies to "clarify whether CCSVI is associated with later disease stages and characterizes the progressive forms of MS" (Ann. Neurol. 2011;69:90-9).
In a position statement, the Society of Interventional Radiology stated that at present, the published literature is "inconclusive on whether CCSVI is a clinically important factor and on whether balloon angioplasty and/or stent placement are effective in patients with MS" (J. Vasc. Interv. Radiol. 2010;21:1335-7).
Additionally, in a commentary on the treatment of CCSVI, representatives of the Cardiovascular and Interventional Radiological Society of Europe acknowledged that although several centers worldwide are promoting and performing balloon dilatation, with or without stenting for CCSVI, "We believe that until real scientific data are available for CCSVI and balloon dilatation, this treatment should not be offered to MS patients outside of a well designed clinical trial" (Cardiovasc. Intervent. Radiol. 2011;34:1-2).
Toward that end, the National Multiple Sclerosis Society of the United States and the MS Society of Canada have pledged $2.4 million in support of seven CCSVI research studies, including projects designed to evaluate venous abnormalities in children and teens with MS, patients with early and late stage MS, and those at risk for MS.
An international review panel comprising radiologists, vascular surgeons, and neurologists evaluated research applications via an expedited review process, according to the societies.
Dr. Burks disclosed relationships with various pharmaceutical companies. Dr. Baracchini had no relevant conflicts.
To say that the relationship between CCSVI and multiple sclerosis is controversial is an understatement. This article introduces both sides of the story and summarizes the current evidence. While many physicians remain understandably skeptical, it is worth remembering that "conventional wisdom" on the pathophysiology of some diseases has turned out to be way off the mark - consider peptic ulcers.

To say that the relationship between CCSVI and multiple sclerosis is controversial is an understatement. This article introduces both sides of the story and summarizes the current evidence. While many physicians remain understandably skeptical, it is worth remembering that "conventional wisdom" on the pathophysiology of some diseases has turned out to be way off the mark - consider peptic ulcers.

Multiple sclerosis patients and endovascular interventionalists were elated when Italian researchers reported in 2009 that they had found evidence of chronic cerebrospinal venous insufficiency in nearly every MS patient they had studied and that in many cases, balloon angioplasty and sometimes stent placement of central thoracic veins reduced or eliminated signs of the disease. Neurologists, on the other hand, suggested that hope might be eclipsing reason in the rush to advocate the vascular procedure, given the single-center study's small sample size and nonrandomized, uncontrolled design.
The opposing perspectives incited an apparent turf war within the MS community fueled by accusations on both sides, according to Dr. Jack Burks, chief medical officer of the Multiple Sclerosis Association of America. At issue, he said, is the validity not only of the study results but also of the underlying hypothesis that toxic iron overload in the brain due to chronic cerebrospinal venous insufficiency (CCSVI) might have a primary role in the pathogenesis of MS - a hypothesis that contradicts the compelling body of evidence suggesting that MS is primarily an autoimmune condition.
On one side of the debate are the MS patients and endovascular interventionalists, dubbed the "liberators" by Dr. Burks because of their unflappable advocacy for what has become known as the liberation procedure - the endovascular surgery designed to open the lesions causing the venous insufficiency, he said.
"Neurologists believe the interventionalists are overstating the possible value of CCSVI and that commercial interests are overriding scientific inquiry," according to Dr. Burks, a neurologist and clinical professor of medicine at the University of Nevada, Reno. Patients, armed with anecdotal evidence downloaded from the Internet, are certain that CCSVI surgery is the miracle they've been waiting for and perceive the hesitancy of U.S. and Canadian neurologists to embrace the treatment as evidence of a possible conspiracy with pharmaceutical companies who stand to lose billions of dollars if the surgery becomes a first-line treatment, he said. Further, he noted, advocates of CCSVI claim that neurologists who refuse patients' demands for diagnostic testing and surgical referral for CCSVI are jeopardizing the safety of those patients, who are traveling to foreign countries to get the care that they cannot receive in North America.
To date, the majority of the evidence regarding CCSVI diagnosis and treatment in MS is inconsistent, and can be confusing, Dr. Burks noted. In the initial study, Dr. Paolo Zamboni of the University of Ferrara in Italy, and colleagues, used Doppler ultrasound to examine venous drainage of the brain and spinal cord in 65 patients with different types of MS and 235 controls without MS and observed abnormal venous flow in all of the MS patients and none of the controls. The patterns of venous obstruction differed depending on MS stage and course, although there was no apparent relationship between disease severity and extent of venous obstruction, and MS treatment status did not influence the signs of CCSVI in any of the patients, the authors wrote (J. Neurol. Neurosurg. Psychiatry 2009;80:392-9).
The researchers went on to conduct an open pilot study to determine whether percutaneous transluminal angioplasty could safely and effectively treat the narrowing of the extracranial cerebrospinal veins in the 65 MS patients in which the condition was observed - 35 with relapsing-remitting MS, 20 with secondary progressive MS, and 10 with primary progressive MS. They reported significant improvements in MS clinical outcome measures, significant reductions in new brain lesions on MRI, and significant reductions in the number of relapses experienced by some of the patients.
The findings were limited, however, not only by the study design, but also by the fact that patients remained on their disease-modifying antirheumatic drug therapy during the study period and the timing and type of MRI scans varied among the patients, according to the authors. They also noted that restenosis of the internal jugular veins occurred in nearly half of the patients (J. Vasc. Surg. 2009;50:1348-58).
Since the initial paper, a number of CCSVI studies of various designs have been undertaken, with contradictory results. Following are some of the investigations reported within the past year:
P Researchers at the University of Buffalo found that up to 62% of the 280 patients with MS enrolled in the Combined Transcranial and Extracranial Venous Doppler Evaluation study - the first randomized clinical trial to evaluate MS patients for CCSVI - had the characteristic narrowing of the extracranial veins compared with approximately 22% of 220 healthy controls. While the results, which were reported at the annual meeting of the American Academy of Neurology, did not establish causation, they showed "that narrowing of the extracranial veins, at the very least, is an important association in multiple sclerosis," principal investigator Dr. Robert Zivadinov said in a statement. He acknowledged that the finding of vascular narrowing in nearly a quarter of the healthy controls warranted additional investigation (www.buffalo.edu/news/fast-execute.cgi/article-page.html?article=109370009).
P In an open-label study of extracranial Doppler criteria of CCSVI in 70 MS patients in Poland - 49 with relapsing-remitting MS, 5 with primary progressive MS, and 16 with secondary progressive MS - investigators detected at least two of four extracranial criteria in 90% of the patients. They concluded that, while the extracranial abnormalities could exist in various combinations, "the most common pathology in our patients was the presence of an inverted valve or another pathologic structure [like membranaceous or netlike septum] in the area of junction of the [internal jugular vein] with the brachiocephalic vein (Int. Angiol. 2010;29:109-14).
P A comparison of the internal jugular vein hemodynamics and morphology in 25 patients with MS and 25 controls identified abnormal findings in 92% of the MS patients and 24% of the controls, and evidence of CCSVI in 84% of the MS patients and none of the controls, leading the investigators to conclude that both hemodynamic abnormalities and morphologic changes in the internal jugular vein "are strongly associated with MS" (Int. Angiol. 2010;29:115-20).
P An extended extra- and transcranial color-coded sonography study in 56 MS patients and 20 controls detected no internal jugular vein stenosis and normal blood flow direction in all but 1 patient. There were no between-group differences in intracranial veins and during Valsalva maneuver, and none of the patients fulfilled more than one CCSVI criterion, according to the authors. They concluded that their findings "challenge the hypothesis that cerebral venous congestion plays a significant role in the pathogenesis of MS" (Ann. Neurol. 2010;68:173-83).
P Swedish investigators used phase-contrast MRI to study 21 relapsing-remitting MS patients and 20 healthy controls and found no differences in internal jugular venous outflow, aqueductal cerebrospinal fluid flow, or the presence of internal jugular blood reflux between the two groups. Although contrast-enhanced MR angiography showed internal jugular vein stenosis in 3 of the 21 MS patients, the authors stated they found no evidence "confirming the suggested vascular multiple sclerosis hypothesis" (Ann. Neurol. 2010;68:255-9).
P The authors of an MR venography and flow quantification study in The Netherlands compared the intracranial and extracranial venous anatomy and the intracerebral venous flow profiles of 20 MS patients and 20 age- and gender-matched controls, with image analysis performed by blinded interventional neuroradiologists. They identified venous system anomalies in 50% of the MS patients and 40% of the healthy controls and no venous backflow in either group. "Given the normal intracranial venous flow quantification results, it is likely that these findings reflect anatomical variants of venous drainage rather than clinically relevant venous outflow obstructions," the authors wrote (J. Neurol. Neurosurg. Psychiatry 2010 Oct. 27 [doi: 10.1136/jnnp.2010.223479]).
P Italian researchers investigating the occurrence of CCSVI in 50 consecutive patients with clinically isolated syndromes suggestive of MS reviewed the patients' extracranial and transcranial venous echo-color Doppler sonographs and compared the findings to those of 50 age- and gender-matched healthy controls as well as those of 60 patients with transient global amnesia (TGA) and 60 healthy controls matched to the TGA patients. They found extracranial Doppler sonographic abnormalities in 52% of patients with possible MS, 68.3% of patients with TGA, and 31.8% of the healthy controls. While eight of the patients with possible MS fulfilled the CCSVI criteria, selective phlebography showed no venous anomalies in seven of them. The authors concluded that there was no evidence of CCSVI at MS onset but recommended further studies to "clarify whether CCSVI is associated with later disease stages and characterizes the progressive forms of MS" (Ann. Neurol. 2011;69:90-9).
In a position statement, the Society of Interventional Radiology stated that at present, the published literature is "inconclusive on whether CCSVI is a clinically important factor and on whether balloon angioplasty and/or stent placement are effective in patients with MS" (J. Vasc. Interv. Radiol. 2010;21:1335-7).
Additionally, in a commentary on the treatment of CCSVI, representatives of the Cardiovascular and Interventional Radiological Society of Europe acknowledged that although several centers worldwide are promoting and performing balloon dilatation, with or without stenting for CCSVI, "We believe that until real scientific data are available for CCSVI and balloon dilatation, this treatment should not be offered to MS patients outside of a well designed clinical trial" (Cardiovasc. Intervent. Radiol. 2011;34:1-2).
Toward that end, the National Multiple Sclerosis Society of the United States and the MS Society of Canada have pledged $2.4 million in support of seven CCSVI research studies, including projects designed to evaluate venous abnormalities in children and teens with MS, patients with early and late stage MS, and those at risk for MS.
An international review panel comprising radiologists, vascular surgeons, and neurologists evaluated research applications via an expedited review process, according to the societies.
Dr. Burks disclosed relationships with various pharmaceutical companies. Dr. Baracchini had no relevant conflicts.

FDA Panel Divided on Trilipix Labeling Changes
SILVER SPRING, MD. — Members of a Food and Drug Administration advisory panel were divided on whether the approved indication for fenofibric acid, when co-administered with a statin, should be revised based on trial results showing no benefit of the drug in reducing cardiovascular disease risk when added to a statin in patients with type 2 diabetes.
At a meeting May 19, 6 of the 13 members of the FDA’s Endocrinologic and Metabolic Drugs Advisory Committee agreed that the marketing of fenofibric acid should be allowed to continue, with the addition to the label of the main findings of the study – the Action to Control Cardiovascular Risk in Diabetes (ACCORD) Lipid trial. Four panelists, however, voted to recommend that the co-administration indication be withdrawn, citing the lack of solid evidence to support the indication. The remaining three panelists voted to allow continued marketing with no changes to the label.
Fenofibric acid, marketed by Abbott Laboratories as Trilipix, was approved by the FDA in December 2008. The drug’s indication includes its use with a statin as an adjunct to diet to reduce serum triglyceride (TG) levels and increase serum HDL cholesterol levels in patients with mixed dyslipidemia and coronary heart disease (CHD) or a CHD risk equivalent who are on "optimal statin therapy" to achieve their LDL cholesterol goal. Fenofibric acid is the active ingredient of fenofibrate, a fibrate approved in 1993 that is now available in generic formulations.
The FDA convened the panel to review the co-administration indication of fenofibric acid in the context of the ACCORD Lipid study results. That study found no benefit of the combination treatment on major cardiovascular events, compared with treatment with simvastatin alone, over a mean of almost 5 years of follow-up. The study enrolled more than 5,500 patients with type 2 diabetes at high risk of cardiovascular disease, with a range of TG and HDL cholesterol levels. Among women in the study, the rate of major adverse cardiovascular events was higher than that among those on the statin alone. But in another subgroup of patients, those with elevated TG levels (204 mg/dL or higher) and reduced HDL cholesterol levels (34 mg/dL or lower), there was a suggestion of benefit with combination therapy (N. Engl. J. Med. 2010;362:1563-74).
Panelists at the meeting said they were not comfortable drawing any conclusions from analyses of patient subgroups in a negative trial. They voted 13-0 that the FDA should require Abbott to conduct a study to test the hypothesis that add-on therapy with fenofibric acid, compared with placebo, significantly lowers the risk of major adverse cardiovascular events in high-risk patients who have reached their LDL cholesterol goal with a statin but have residual high serum TG and low serum HDL cholesterol levels.
The ACCORD Lipid study was sponsored by the National Heart, Lung and Blood Institute.
The FDA usually follows the recommendations of its advisory panels. Members of FDA advisory panels have been cleared of potential conflicts of interest related to the topic of the meeting; occasionally, they may be given a waiver, but not at this meeting.

FROM A MEETING OF THE FDA'S ENDOCRINOLOGIC AND METABOLIC DRUGS ADVISORY PANEL
Nonclinical Skills Essential to Successful HM Career
Being a good hospitalist means more than being an adroit clinician. But when it comes to teaching nonclinical aptitude, traditional residency programs often come up short, says Russell Holman, MD, MHM, former SHM president and chief clinical officer of Brentwood, Tenn.-based Cogent Healthcare. He and other HM experts recommend that boots-on-the-ground hospitalists acquire the following nonclinical skills in a purposeful manner as part of their ongoing learning and long-term career goals.
Communication
Hospitalists are the liaison between hospital administrators, managed-care companies, case managers, patients, patients’ families, and primary-care physicians (PCPs), says Isela Sotolongo, executive director of the Southeast region for North Hollywood, Calif.-based IPC: The Hospitalist Company. “A lot of times, more time is spent communicating with all the individuals that are involved in the patient’s admission than is actually spent with the patient,” she says.

—Isela Sotolongo, executive director, Southeast region, IPC: The Hospitalist Company, North Hollywood, Calif.
Hospitalists must quickly establish a relationship with patients and their families; manage specialists and ancillary personnel; brief a PCP on a patient’s needs after discharge; update case managers on a course of hospitalization; and demonstrate effective, efficient patient care to hospital administrators. Being able to express such information in a concise manner that is understood by others will reduce errors and save time and effort, Dr. Holman and Sotolongo say.
Quality Improvement (QI)
An awareness and working knowledge of QI methodologies should be part of a hospitalist’s everyday professional life, Dr. Holman says. QI helps reduce unwanted variation in patient care and enhances the process and outcomes of such care.
“Hospitalists are almost always looked to as being a linchpin in the hospital to improving quality,” he says. Therefore, while QI might not be a hospitalist’s special interest, it is still good to know the basics and how to apply them to actual HM practice, Dr. Holman says.
Leadership
“Even if a hospitalist is not serving as medical director of their hospital medicine group, they are considered to be a leader in their own right,” Dr. Holman says.
A hospitalist takes charge of the admission process and is the person who manages all aspects of a patient’s care throughout the hospital stay to the point of discharge, Sotolongo says. (Click here to listen to Isela Sotolongo discuss hospitalist leadership and communication in detail.)
Also, a hospitalist might be leading and participating in QI activities at the hospital or leading the discussion for a multidisciplinary team, Dr. Holman notes. Having leadership skills helps a hospitalist appreciate the work their medical director must do, or the work that hospital administrators are trying to accomplish, he says.
Teamwork
Teamwork is an essential skill for hospitalists, yet traditional medical training often teaches doctors to be more of a rugged individualist, Dr. Holman says. Hospitalists should make it a point to adopt new behaviors that are teamwork-friendly:
- Value other members of the healthcare team;
- Direct people’s talents to their highest and best use; and
- Delegate tasks to those who are best suited to accomplish those particular needs.
“Teamwork tends to place much more emphasis on the patient being the center of care and others on the healthcare team going to support those patient-centered interests,” Dr. Holman say.
The Patient Perspective
How a patient moves through the healthcare system in theory is often different from reality. A hospitalist should physically follow some of their patients as they move from the hospital back to their caregivers at home or to a rehabilitation center, nursing home, or other facility in order to watch the transition, says Jasen Gundersen, MD, MBA, CPE, SFHM, chief medical officer of the hospital medicine division in Fort Lauderdale, Fla., for Knoxville, Tenn.-based TeamHealth. By doing this, a hospitalist can see where problems arise during handoffs and how to resolve them so that hospital readmissions are reduced.
Teaching
Teaching skills can be applicable in any hospital environment, Dr. Holman adds. Hospitalists who work in nonteaching hospitals often serve as teachers to nursing staff, case management, pharmacists, discharge planners, and other ancillary staff in their daily interaction or over lunchtime educational programs. HM also can provide the bulk of a hospital’s grand rounds or other departmental educational sessions, he says.
“Let's not forget about patients and caregivers,” Dr. Holman adds. “The ability to teach patients and caregivers the necessary information and skills that they need for self-care, for follow-up care, and for compliance to a medical plan is important.”
Professional Evaluation
A hospitalist has to know on which metrics and measurements their success will be based, Dr. Holman says. Will it be patient satisfaction, length of stay, readmission rates, mortality rates, or some other measure?
“We have to be aware of what the hospital’s needs are, what the hospital’s key points are that they look for,” Sotolongo says.
Once the metrics are clear, a hospitalist can set goals to accomplish individually, as a member of an HM group, and partner with the hospital, Dr. Holman says.

Being a good hospitalist means more than being an adroit clinician. But when it comes to teaching nonclinical aptitude, traditional residency programs often come up short, says Russell Holman, MD, MHM, former SHM president and chief clinical officer of Brentwood, Tenn.-based Cogent Healthcare. He and other HM experts recommend that boots-on-the-ground hospitalists acquire the following nonclinical skills in a purposeful manner as part of their ongoing learning and long-term career goals.
Communication
Hospitalists are the liaison between hospital administrators, managed-care companies, case managers, patients, patients’ families, and primary-care physicians (PCPs), says Isela Sotolongo, executive director of the Southeast region for North Hollywood, Calif.-based IPC: The Hospitalist Company. “A lot of times, more time is spent communicating with all the individuals that are involved in the patient’s admission than is actually spent with the patient,” she says.

Hospitalists must quickly establish a relationship with patients and their families; manage specialists and ancillary personnel; brief a PCP on a patient’s needs after discharge; update case managers on a course of hospitalization; and demonstrate effective, efficient patient care to hospital administrators. Being able to express such information in a concise manner that is understood by others will reduce errors and save time and effort, Dr. Holman and Sotolongo say.
Quality Improvement (QI)
An awareness and working knowledge of QI methodologies should be part of a hospitalist’s everyday professional life, Dr. Holman says. QI helps reduce unwanted variation in patient care and enhances the process and outcomes of such care.
“Hospitalists are almost always looked to as being a linchpin in the hospital to improving quality,” he says. Therefore, while QI might not be a hospitalist’s special interest, it is still good to know the basics and how to apply them to actual HM practice, Dr. Holman says.
Leadership

SHM Leaders Field Constituent Questions in Town Hall
The vast majority of the more than 2,500 attendees last week at SHM's annual meeting in Grapevine, Texas, were already on their way to the airport when one last dedicated group discussed the future of the specialty.
The question-and-answer session took place at the annual SHM Town Hall, a chance for rank-and-file hospitalists to query society board members and leaders. Some 75 people took turns asking about internal-medicine residency programs, the challenges of maintaining robust society chapters, and HM's role in critical-care delivery. But the theme of the session kept coming back to whether hospitalists have a seat at the table in how healthcare reform is implemented.
Board member and former SHM Public Policy Committee chairman Eric Siegal, MD, SFHM, says that the society has quickly risen in stature in policy circles despite being a newer specialty. He adds that the field's prominence and credibility is helped by the recent appointment of Patrick Conway, MD, MSc, SFHM, a pediatric hospitalist and director of hospital medicine at Cincinnati Children’s Hospital Medical Center, as chief medical officer of the Centers for Medicare & Medicaid Services (CMS).
"We punch well above our weight class right now," says Dr. Siegal, a critical-care fellow at the University of Wisconsin School of Medicine and Public Health in Madison.
In an interesting twist, James Levy, PA-C, suggested that SHM expand its fellowship programs to nonphysician providers (NPPs) as a way of making them feel more included. Several board members nodded and said they would consider the notion.
"We are actually a big-tent society," says board member Daniel Dressler, MD, MSc, SFHM, associate professor and director of internal-medicine teaching services at Emory University Hospital in Atlanta.

In the Literature: Research You Need to Know
Clinical Question: Is chest-compression-only bystander cardiopulmonary resuscitation (CPR) as effective as conventional CPR with rescue breathing for out-of-hospital cardiac arrest?
Background: Out-of-hospital cardiac arrest is a major public health problem, affecting approximately 300,000 people in the U.S. annually. Overall survival is generally less than 10% among those in whom resuscitation is attempted. Bystander CPR significantly improves outcomes but generally is performed in less than 30% of cases.
Study design: Prospective, observational cohort study.
Setting: Communities throughout the state of Arizona.
Synopsis: State officials undertook a multifaceted public service campaign to educate, inform, and encourage the use of compression-only CPR.
Over a period of four years, 5,272 adult out-of-hospital cardiac arrests were documented in Arizona. A total of 4,415 of these incidents met all of the inclusion criteria for analysis; 2,900 received no CPR, 666 received conventional CPR, and 849 received compression-only CPR. Rates of survival to hospital discharge were 5.2% for the no-CPR group, 7.8% for conventional CPR, and 13.3% for compression-only CPR.
Additionally, the successful public service campaign increased the use of lay rescuer conventional CPR by 10% and compression-only CPR by 56%.
Bottom line: Layperson, compression-only CPR was associated with an overall 6.1% increased survival compared with conventional CPR and no bystander CPR.
