There are 30 million adults (12%) in the United States who have chronic obstructive pulmonary disease (COPD). Chronic obstructive pulmonary disease accounts for 3.2% of all physician office visits annually and is the fourth leading cause of death (126 000 deaths per year). Most patients are diagnosed by their primary care clinicians who must address the highly variable clinical features and responses to therapy. The diagnosis and treatment of COPD is rapidly changing, so understanding recent advances is important for the delivery of optimal patient care. ⋯ Chronic obstructive pulmonary disease is a complicated disease requiring intensive treatment. Appropriate use of long-acting maintenance bronchodilators, inhaled corticosteroids, and pulmonary rehabilitation decreases symptoms, optimizes functional performance, and reduces exacerbation frequency. Supplemental oxygen in patients with resting hypoxemia prolongs life, and other advanced treatments are available based on specific patient characteristics.

Overlapping surgery, in which more than 1 procedure performed by the same primary surgeon is scheduled so the start time of one procedure overlaps with the end time of another, is of concern because of potential adverse outcomes. ⋯ Among adults undergoing common operations, overlapping surgery was not significantly associated with differences in in-hospital mortality or postoperative complication rates but was significantly associated with increased surgery length. Further research is needed to understand the association of overlapping surgery with these outcomes among specific patient subgroups.
