To investigate whether HIV is associated with an increased risk of acute myocardial infarction, Freiberg and coworkers enrolled participants from the Veterans Aging Cohort Study Virtual Cohort, a sample of HIV-positive and uninfected veterans in care matched for age, sex, race/ethnicity, and clinical site. See the invited commentary by Mallon.
Oduyebo and coauthors determined the frequency with which inpatient providers report communicating directly with outpatient providers and whether direct communication was associated with 30-day readmissions. Also see the Invited Commentary by Marks.
Donzé et al evaluated 30-day hospital readmissions during a 1-year period to identify predictors and develop a model to predict potentially avoidable readmissions. An invited commentary by Marks follows.
Xiao and coauthors investigate whether intake of dietary and supplemental calcium is associated with mortality from total cardiovascular disease, heart disease, and cerebrovascular diseases. See invited commentary by Larsson.
To determine the effects of the 2011 vs 2003 ACGME duty hour regulations concerning sleep duration, trainee education, continuity of care, and perceived quality of care among 43 internal medicine trainees, Desai et al used a 3-month crossover study design and random assignment of 4 medical house staff teams. Wristwatch actigraphy and satisfaction surveys were used. See invited commentary by Goitein and Ludmerer and letter to the editor by Spellberg et al.
Sen and coauthors conducted a longitudinal cohort study of interns in 1 of 51 residency programs at 14 university and community-based GME institutions or graduating from 1 of 4 medical schools, comparing duty hours, hours of sleep, depressive symptoms, well-being, and medical errors before and after the implementation of the 2011 duty-hour requirements.
Tzoulaki and coworkers gathered meta-analyses of cardiovascular biomarkers and evaluated whether large studies had significantly more conservative results than smaller studies and whether there were too many studies with statistically significant results compared with what would be expected. See the invited commentary by Nissen and the viewpoint by Svensson et al.
Daneman and coworkers sought to describe the variability in the duration of antibiotic treatment courses in long-term care across resident recipients and prescribing physicians and to determine whether this variability is influenced by prescriber preference. See invited commentary by Hughes and Tunney.
McConnell et al offer evidence on the effectiveness of manufacturing approaches to improve quality of care in hospitals by defining management dimensions and measuring them in a sample of cardiac care hospital units. An invited commentary by Armstrong et al follows.
Burke and Coleman use relevant literature and experience to identify 5 creative strategies to reduce 30-day readmission rates for certain diagnoses. An invited commentary by Marks follows.
