Long-term azithromycin therapy has been shown to reduce exacerbations of chronic obstructive pulmonary disease (COPD), and is recommended by recent society guidelines for use in COPD patients who are at risk for recurrent exacerbations. However, concerns about adverse effects have limited its widespread adoption. Physicians deciding whether to use long-term azithromycin therapy must weigh each patient's individual risk of cardiovascular complications and both the individual and population impact of macrolide resistance against the expected benefit. This review will summarize evidence on the effectiveness and safety of chronic azithromycin for the prevention of COPD exacerbations.

Four direct oral anticoagulants (DOACs) have been brought to market for the treatment of nonvalvular atrial fibrillation and venous thromboembolism. Many forces, including numerous positive trial results, emerging safety concerns, marketing, and promotion, may shape DOAC adoption by providers. However, relatively little is known regarding their ambulatory utilization compared with warfarin, as well as the degree to which they have decreased under-treatment of atrial fibrillation. ⋯ Direct oral anticoagulants have been adopted rapidly, matching the use of warfarin, and are associated with increased use of oral anticoagulation for patients with atrial fibrillation.

Oversights in the physical examination are a type of medical error not easily studied by chart review. They may be a major contributor to missed or delayed diagnosis, unnecessary exposure to contrast and radiation, incorrect treatment, and other adverse consequences. Our purpose was to collect vignettes of physical examination oversights and to capture the diversity of their characteristics and consequences. ⋯ Physical examination inadequacies are a preventable source of medical error, and adverse events are caused mostly by failure to perform the relevant examination.
