BACKGROUND Hospitals across the United States are pursuing strategies to reduce avoidable readmissions but the evidence on how best to accomplish this goal is mixed, with no specific clinical practice shown to reduce readmissions consistently. Changes to hospital organizational practices, a key component of context, also may be critical to improving(More)
Every year for the past decade, approximately 50,000 people have been diagnosed with HIV or AIDS in the USA, and the incidence of HIV/AIDS varies considerably from state to state. Studies have shown that health care services, most notably treatment with combination antiretroviral therapy, can help people living with HIV/AIDS (PLWHA) live healthier, longer(More)
BACKGROUND Hospital quality improvement efforts absorb substantial time and resources, but many innovations fail to integrate into organizational routines, undermining the potential to sustain the new practices. Despite a well-developed literature on the initial implementation of new practices, we have limited knowledge about the mechanisms by which(More)
BACKGROUND Physician leadership development programs typically aim to strengthen physicians' leadership competencies and improve organizational performance. We conducted a systematic review of medical literature on physician leadership development programs in order to characterize the setting, educational content, teaching methods, and learning outcomes(More)
BACKGROUND Despite recent reductions in national unplanned readmission rates, we have relatively little understanding of which hospital strategies are most associated with changes in risk-standardized readmission rates (RSRR). OBJECTIVE We examined associations between the change in hospital 30-day RSRR for patients with heart failure and the uptake of(More)
BACKGROUND Improving outcomes for patients with acute myocardial infarction (AMI) is a priority for hospital leadership, clinicians, and policymakers. Evidence suggests links between hospital organizational culture and hospital performance; however, few studies have attempted to shift organizational culture in order to improve performance, fewer have(More)
BACKGROUND HIV medication nonadherence is a major problem, yet many providers lack the time and training to carefully ask patients about their adherence. OBJECTIVE To design and pilot a technology-assisted intervention, for use in clinical settings, to identify nonadherent patients. METHODS The intervention uses audio computer-assisted self-interview(More)
BACKGROUND Despite evidence that enrollment with hospice services has the potential to reduce hospital readmission rates, previous research has not examined exactly how hospitals may promote the appropriate use of hospice and palliative care for their discharged patients. Therefore, we sought to explore the strategies used by hospitals to increase the use(More)
BACKGROUND Because organizational culture is increasingly understood as fundamental to achieving high performance in hospital and other healthcare settings, the ability to measure this nuanced concept empirically has gained importance. Aside from measures of patient safety culture, no measure of organizational culture has been widely endorsed in the medical(More)
BACKGROUND Survival rates after acute myocardial infarction (AMI) vary markedly across U.S. hospitals. Although substantial efforts have been made to improve hospital performance, we lack contemporary evidence about changes in hospital strategies and features of organizational culture that might contribute to reducing hospital AMI mortality rates. We sought(More)
