Background

Although the Accreditation Council for Graduate Medical Education (ACGME) limits the work hours of residents, concerns about fatigue persist. A new Institute of Medicine (IOM) report recommends, among other changes, improved adherence to the 2003 ACGME limits, naps during extended shifts, a 16-hour limit for shifts without naps, and reduced workloads.

Methods

We used published data to estimate labor costs associated with transferring excess work from residents to substitute providers, and we examined the effects of our assumptions in sensitivity analyses. Next, using a probability model to represent labor costs as well as mortality and costs associated with preventable adverse events, we determined the net costs to major teaching hospitals and cost-effectiveness across a range of hypothetical changes in the rate of preventable adverse events.

Results

Annual labor costs from implementing the IOM recommendations were estimated to be $1.6 billion (in 2006 U.S. dollars) across all ACGME-accredited programs ($1.1 billion to $2.5 billion in sensitivity analyses). From a 10% decrease to a 10% increase in preventable adverse events, net costs per admission ranged from $99 to $183 for major teaching hospitals and from $17 to $266 for society. With 2.5% to 11.3% decreases in preventable adverse events, costs to society per averted death ranged from $3.4 million to $0.

Conclusions

Implementing the four IOM recommendations would be costly, and their effectiveness is unknown. If highly effective, they could prevent patient harm at reduced or no cost from the societal perspective. However, net costs to teaching hospitals would remain high.

The American College of Cardiology Foundation (ACCF), along with key specialty and subspecialty societies, conducted an appropriate use review of common clinical scenarios where cardiac radionuclide imaging (RNI) is frequently considered. This document is a revision of the original Single-Photon Emission Computed Tomography Myocardial Perfusion Imaging (SPECT MPI) Appropriateness Criteria,1 published 4 years earlier, written to reect changes in test utilization and new clinical data, and to clarify RNI use where omissions or lack of clarity existed in the original criteria. This is in keeping with the commitment to revise and rene appropriate use criteria (AUC) on a frequent basis. The indications for this review were drawn from common applications or anticipated uses, as well as from current clinical practice guidelines. Sixty-seven clinical scenarios were developed by a writing group and scored by a separate technical panel on a scale of 1 to 9 to designate appropriate. In general, use of cardiac RNI for diagnosis and risk assessment in intermediate- and high-risk patients with coronary artery disease (CAD) was viewed favorably, while testing in low-risk patients, routine repeat testing, and general screening in certain clinical scenarios were viewed less favorably. Additionally, use for perioperative testing was found to be inappropriate except for high selected groups of patients. It is anticipated that these results will have a signicant impact on physician decision making, test performance, and reimbursement policy, and will help guide future research.

AIMS: The purpose of these analyses was to examine the persistence and predictors of elevated depressive symptoms in 884 women over their children's preschool years. RESULTS: Depressive symptoms in women with young children are surprisingly consistent throughout their children's preschool years. Of the 82.6% of women without elevated depressive symptoms at the initial assessment (study child was 11-42 months of age), 82.4% remained without symptoms over two follow-up assessments. Of 17.4% of women with elevated symptoms at baseline, 35.6% had elevated symptoms at one of the two follow-ups, and 27.4% had elevated symptoms at both follow-ups. Persistently elevated depressive symptoms were related to low education, high levels of anxiety, high parenting distress, and low levels of emotional support at baseline. CONCLUSIONS: Women who report symptoms of depression when their children are young are highly likely to continue to report such symptoms. These results support the need to screen for elevated depressive symptoms at varying intervals depending on prior screening results and for screening in locations where women most at risk routinely visit, such as well-child clinics. Further, these results point to the need for a system to identify and manage this common treatable condition because these elevated symptoms continue throughout their children's preschool years for a substantial portion of women.

Who pays the healthcare costs associated with obesity? Among workers, this is largely a question of the incidence of the costs of employer-sponsored coverage. Using data from the National Longitudinal Survey of Youth and the Medical Expenditure Panel Survey, we find that the incremental healthcare costs associated with obesity are passed on to obese workers with employer-sponsored health insurance in the form of lower cash wages. Obese workers without employer-sponsored insurance do not have a wage offset relative to their non-obese counterparts. A substantial part of the lower wages among obese women attributed to labor market discrimination can be explained by their higher health insurance premiums.

OBJECTIVE: To examine parent concerns about development, learning, and behavior for young children of Mexican origin, and to identify whether these reports differ by families' citizenship/documentation status.

METHODS: Data come from the 2005 California Health Interview Survey, a population-based random-digit dial telephone survey of California's noninstitutionalized population. California Health Inerview Survey (CHIS) investigators completed interviews of 43 020 households with a total of 5856 children under age 6 years, of whom 1786 were reported being of Mexican origin. Developmental risk was measured by parent concerns elicited by the Parents' Evaluation of Developmental Status. We used bivariate and multivariate analyses to examine associations between developmental risk and family citizenship/documentation status (parents are undocumented, at least one documented noncitizen parent, or both parents are US citizens) among children of Mexican origin and US-born non-Latino white children, after adjusting for age, income, parental education, and predominant household language.

RESULTS: In multivariate analyses, children of Mexican origin did not differ significantly from US-born white children in developmental risk (odds ratio 1.12, 95% confidence interval 0.88-1.42). In subgroup analyses, children of Mexican origin with undocumented parents had higher odds of developmental risk (odds ratio 1.53, 95% confidence interval 1.00-2.33) than non-Latino white children whose parents were citizens, after adjusting for confounders.

CONCLUSIONS: Mexican children with undocumented parents have greater parent-reported developmental risk than Mexican and white children whose parents are US citizens or otherwise legally documented. More research is needed to understand the roles of immigration stress and home environments on the developmental risks of children in households with undocumented parents.

STUDY DESIGN: Clinical practice guideline.

OBJECTIVE: To develop evidence-based recommendations on use of interventional diagnostic tests and therapies, surgeries, and interdisciplinary rehabilitation for low back pain of any duration, with or without leg pain.

SUMMARY OF BACKGROUND DATA: Management of patients with persistent and disabling low back pain remains a clinical challenge. A number of interventional diagnostic tests and therapies and surgery are available and their use is increasing, but in some cases their utility remains uncertain or controversial. Interdisciplinary rehabilitation has also been proposed as a potentially effective noninvasive intervention for persistent and disabling low back pain.

METHODS: A multidisciplinary panel was convened by the American Pain Society. Its recommendations were based on a systematic review that focused on evidence from randomized controlled trials. Recommendations were graded using methods adapted from the US Preventive Services Task Force and the Grading of Recommendations, Assessment, Development, and Evaluation Working Group.

RESULTS: Investigators reviewed 3348 abstracts. A total of 161 randomized trials were deemed relevant to the recommendations in this guideline. The panel developed a total of 8 recommendations.

CONCLUSION: Recommendations on use of interventional diagnostic tests and therapies, surgery, and interdisciplinary rehabilitation are presented. Due to important trade-offs between potential benefits, harms, costs, and burdens of alternative therapies, shared decision-making is an important component of a number of the recommendations.

Background and objectives: Changes in ESRD reimbursement policy, including proposed bundled payment, have raised concern that dialysis facilities may use "cherry picking" practices to attract a healthier, better insured, or more adherent patient population.

Design, setting, participants, & measurements: As part of a national survey to measure beliefs about drivers of quality in dialysis, respondents were asked about their perceptions of cherry picking, including the frequency and effect of various cherry picking strategies on dialysis outcomes. We surveyed a random sample of 250 nurse members of the American Nephrology Nurses Association, 250 nephrologist members of the American Medical Association, 50 key opinion leaders, and 2000 physician members of the Renal Physicians Association. We tested hypothesized predictors of perception, including provider group, region, age, experience, and the main practice facility features.

Results: Three-quarters of respondents reported that cherry picking occurred "sometimes" or "frequently." There were no differences in perceptions by provider or facility characteristics, insurance status, or health status. In multivariable regression, perceived cherry picking was 2.8- and 3.5-fold higher in the northeast and Midwest, respectively, versus the west. Among various cherry picking strategies, having a "low threshold to ‘fire' chronic no-shows/late arrivers," and having a "low threshold to ‘fire' for noncompliance with diet and meds" had the largest perceived association with outcomes.

Conclusions: Under current reimbursement practices, dialysis caregivers perceive that cherry picking is common and important. An improved understanding of cherry picking practices, if evident, may help to protect vulnerable patients if reimbursement practices were to change.

BACKGROUND: Women are at higher risk than men for adverse events with certain invasive cardiac procedures. Our objective was to compare rates of in-hospital adverse events in men and women receiving implantable cardioverter- defibrillator (ICD) therapy in community practice.

METHODS AND RESULTS: Using the National Cardiovascular Data Registry ICD Registry, we identified patients undergoing first-time ICD implantation between January 2006 and December 2007. Outcomes included in-hospital adverse events after ICD implantation. Multivariable analysis assessed the association between gender and in-hospital adverse events, with adjustment for demographic, clinical, procedural, physician, and hospital characteristics. Of 161,470 patients, 73% were male, and 27% were female. Women were more likely to have a history of heart failure (81% versus 77%, P<0.01), worse New York Heart Association functional status (57% versus 50% in class III and IV, P<0.01), and nonischemic cardiomyopathy (44% versus 27%, P<0.01) and were more likely to receive biventricular ICDs (39% versus 34%, P<0.01). In unadjusted analyses, women were more likely to experience any adverse event (4.4% versus 3.3%, P<0.001) and major adverse events (2.0% versus 1.1%, P<0.001). In multivariable models, women had a significantly higher risk of any adverse event (OR 1.32, 95% CI 1.24 to 1.39) and major adverse events (OR 1.71, 95% CI 1.57 to 1.86).

CONCLUSIONS: Women are more likely than men to have in-hospital adverse events related to ICD implantation. Efforts are needed to understand the reasons for higher ICD implantation-related adverse event rates in women and to develop strategies to reduce the risk of these events.

BACKGROUND: Less than one third of the 65 million Americans with hypertension have adequate blood pressure (BP) control. This study examined the effectiveness of 2 interventions for improving patient BP control. METHODS: This was a 2-level (primary care provider and patient) cluster randomized trial with 2-year follow-up occurring among patients with hypertension enrolled from a Veterans Affairs Medical Center primary care clinic. Primary care providers (n = 17) in the intervention received computer-generated decision support designed to improve guideline concordant medical therapy at each visit; control providers (n = 15) received a reminder at each visit. Patients received usual care or a bimonthly tailored nurse-delivered behavioral telephone intervention to improve hypertension treatment. The primary outcome was proportion of patients who achieved a BP <140/90 mm Hg (<130/85 for diabetic patients) over the 24-month intervention. RESULTS: Of the 816 eligible patients contacted, 190 refused and 38 were excluded. The 588 enrolled patients had a mean age of 63 years, 43% had adequate baseline BP control, and 482 (82%) completed the 24-month follow-up. There were no significant differences in amount of change in BP control in the 3 intervention groups as compared to the hypertension reminder control group. In secondary analyses, rates of BP control for all patients receiving the patient behavioral intervention (n = 294) improved from 40.1% to 54.4% at 24 months (P = .03); patients in the nonbehavioral intervention group improved from 38.2% to 43.9% (P = .38), but there was no between-group differences at the end of the study. CONCLUSION: The brief behavioral intervention showed improved outcomes over time, but there were not significant between group differences.
