Traditional, outpatient pulmonary rehabilitation provided to stable COPD patients leads to significant improvements in dyspnea, exercise capacity and health related quality of life. Also, when started during or shortly after a hospitalization for a COPD exacerbation, pulmonary rehabilitation improves these patient-centered outcomes and arguably reduces subsequent health care utilization and mortality. Despite these benefits, the uptake of traditional pulmonary rehabilitation remains disappointingly poor. Home-based pulmonary rehabilitation, a safe and effective alternative to traditional, center-based programs, can broaden access. While proven improvements in dyspnea, exercise capacity and health status justify implementation of home-based pulmonary rehabilitation, it would be helpful to know whether it can also decrease health care utilization and be cost-effective.
