Initial Award Abstract
Chronic obstructive pulmonary disease (COPD) is a progressive, debilitating, irreversible condition accounting for significant population morbidity and mortality. Pulmonary rehabilitation is a program consisting of exercise, education, and social support that is used in the treatment of COPD. Despite support for its short-term benefits such as improved exercise ability and reduction in symptoms of breathlessness, we do not know how long these benefits last. While exercise is an important part of pulmonary rehabilitation, it is not well understood how behavior changes after rehabilitation such as adopting a regular exercise regimen are related to long-term benefits of pulmonary rehabilitation.

This project aims to investigate how adopting a regular exercise regimen after completing pulmonary rehabilitation can help COPD patients sustain better exercise ability and reductions in breathlessness gained from pulmonary rehabilitation. The goal of this project will be achieved through three steps: (1) statistical analysis of existing data collected from a previous study evaluating a one-year maintenance program following completion of pulmonary rehabilitation, (2) collection of new 5-7 year follow-up data on the participants from the previous study to determine if changes in exercise behavior occurred, and (3) identification of psychological and disease factors related to patient’s adoption of a regular exercise regimen. Existing and new follow-up data will include patients’ level of physical activity, quality of life, disease severity, exercise ability, and symptoms of breathlessness.

Evaluation of the role of adherence to exercise as evidence of behavior change will contribute to the understanding of the long-term benefits of pulmonary rehabilitation on tobacco-related lung disease. This is important in the identification of: (1) patients likely to maintain benefits gained from pulmonary rehabilitation, and (2) longer-term outcomes in COPD that are affected by behavior change. Further understanding of these key issues will help facilitate continued improvements in current interventions for patients with COPD.
