Comparative StudyEarly mortality after aortic valve replacement with mechanical prosthetic vs bioprosthetic valves among Medicare beneficiaries: a population-based cohort study.
Early mortality for patients who undergo aortic valve replacement (AVR) may differ between mechanical and biological prosthetic (hereinafter referred to as bioprosthetic) valves. Clinical trials may have difficulty addressing this issue owing to limited sample sizes and low mortality rates. ⋯ In this cohort analysis of Medicare beneficiaries, use of mechanical aortic valves was associated with a higher risk for death on the date of surgery and within the 30 days after surgery compared with bioprosthetic aortic valves among patients who underwent concurrent AVR and coronary artery bypass graft but not isolated AVR.

Home-based primary care and the risk of ambulatory care-sensitive condition hospitalization among older veterans with diabetes mellitus.
Primary care services based at home have the potential to reduce the likelihood of hospitalization among older adults with multiple chronic diseases. ⋯ Home-Based Primary Care is associated with a decreased probability of ambulatory care-sensitive condition hospitalization among elderly veterans with diabetes mellitus. In accountable care models, HBPC may have an important role in the management of older adults with multiple chronic diseases.

Quality of care for elderly patients hospitalized for pneumonia in the United States, 2006 to 2010.
Nearly every US acute care hospital reports publicly on adherence to recommended processes of care for patients hospitalized with pneumonia. However, it remains uncertain how much performance of these process measures has improved over time or whether performance is associated with superior patient outcomes. ⋯ Performance of processes of care for elderly patients hospitalized for pneumonia improved substantially from 2006 to 2010. Adjusted 30-day mortality declined slightly over time primarily owing to improved survival among non-ICU patients, and all individual processes of care were independently associated with reduced mortality.

Multicenter Study Comparative StudyHospital performance for pharmacologic venous thromboembolism prophylaxis and rate of venous thromboembolism : a cohort study.
Hospitalization for acute medical illness is associated with increased risk of venous thromboembolism (VTE). Although efforts designed to increase use of pharmacologic VTE prophylaxis are intended to reduce hospital-associated VTE, whether higher rates of prophylaxis reduce VTE in medical patients is unknown. ⋯ The occurrence of 90-day VTE in medical patients after hospitalization is low. Patients who receive care at hospitals that have lower rates of pharmacologic prophylaxis do not have higher adjusted hazards of VTE, even after accounting for individual receipt of pharmacologic prophylaxis. Efforts to increase rates of pharmacologic VTE prophylaxis in hospitalized medical patients may not substantively reduce this adverse outcome.

Comparative StudyThe association between residency training and internists' ability to practice conservatively.
Growing concern about rising costs and potential harms of medical care has stimulated interest in assessing physicians' ability to minimize the provision of unnecessary care. ⋯ Regardless of overall medical knowledge, internists trained at programs in hospital referral regions with lower-intensity medical practice are more likely to recognize when conservative management is appropriate. These internists remain capable of choosing an aggressive approach when indicated.
