Approximately 20% of patients hospitalized for COPD exacerbations in the United States will be readmitted within 30 days. The Centers for Medicare and Medicaid Services has recently proposed to revise the Hospital Readmissions Reduction Program to financially penalize hospitals with high all-cause 30-day rehospitalization rates after a hospitalization for COPD exacerbation on or after October 1, 2014.To report the results of a systematic review of randomized clinical trials evaluating interventions to reduce the rehospitalizations after COPD exacerbations.Multiple electronic databases were systematically searched to identify relevant studies published between January 1966 and June 2013. Titles, abstracts, and, subsequently, full-text articles were assessed for eligibility. Each study was appraised using predefined criteria.Among 913 titles and abstracts screened, 5 studies (1,393 participants) met eligibility criteria. All studies had a primary outcome of rehospitalization at 6 or 12 months. No study examined 30-day rehospitalization as the primary outcome. Each study tested a different set of interventions. Two studies (one conducted in Canada and one conducted in Spain and Belgium) showed a decrease in all-cause rehospitalization over 12 months in the intervention group versus comparator group (mean number of hospitalizations per patient, 1.0 vs. 1.8; P = 0.01; percent hospitalized, 45 vs. 67%; P = 0.028; respectively). The only study conducted in the United States found a greater than twofold higher risk of mortality in the intervention group (17 vs. 7%, P = 0.003) but no significant difference in rehospitalizations. It was unclear which set of interventions was effective or harmful.The evidence base is inadequate to recommend specific interventions to reduce rehospitalizations in this population and does not justify penalizing hospitals for high 30-day rehospitalization rates after COPD exacerbations.

About 20% of patients hospitalized for chronic obstructive pulmonary disease (COPD) exacerbations are readmitted within 30 days. High 30-day risk-standardized readmission rates after COPD exacerbations will likely place hospitals at risk for financial penalties from the Centers for Medicare and Medicaid Services starting in fiscal year 2015. Factors contributing to hospital readmissions include healthcare quality, access to care, coordination of care between hospital and ambulatory settings, and factors linked to socioeconomic resources (e.g., social support, stable housing, transportation, and food). These concerns are exacerbated at minority-serving institutions, which provide a disproportionate share of care to patients with low socioeconomic resources. Solutions tailored to the needs of minority-serving institutions are urgently needed. We recommend research that will provide the evidence base for strategies to reduce readmissions at minority-serving institutions. Promising innovative approaches include using a nontraditional healthcare workforce, such as community health workers and peer-coaches, and telemedicine. These strategies have been successfully used in other conditions and need to be studied in patients with COPD.
