Summary
COPD currently afflicts 24 million US residents; the prevalence of COPD is high among Veterans. Persons with COPD have significant functional disability as a result of the disease. This project will determine whether a novel Internet-mediated walking program coupled with a pedometer can improve exercise capacity, improve health-related quality of life, and decrease the risk of acute exacerbations in persons with COPD. If successful, based on estimates that 33 to 64% of COPD patients are Internet users, the proposed exercise intervention could help over 8 million persons. The Veterans Health Administration (VHA) has a strong commitment to providing care to persons with COPD and supporting research directed at COPD-related disability. The 2012-2016 Strategic Plan of the VHA Office of Research and Development includes research in COPD rehabilitation. The proposed research addresses Rehabilitation R&D Service's current priority area of improving disabled Veterans' health-related quality of life by reducing disease burden and maximizing functional recovery.
