The Long-Term Benefits of Outpatient Pulmonary Rehabilitation on Exercise Endurance and Quality of Life

Abstract

Although it is generally accepted that outpatient pulmonary rehabilitation (OPR) improves exercise performance and quality of life (QOL), it is not well established whether these gains are sustained over time. To evaluate this, we attempted to contact the 71 patients who had completed our 6-week OPR program for follow-up 12-min walking distance (12 MD) and QOL measurements. Fifty-one patients (71.8 percent) returned for follow-up testing 11.0 ± 6.1 months following OPR. Of these, 19 had participated in a structured post-OPR exercise maintenance (EM) program, while 32 had not (non-EM). The 12 MD increased from 2,300 ± 611 ft at baseline to 2,789 ± 622 ft post-OPR, while the QOL (higher is better) increased from 81.2 ± 21.4 to 104.7 ± 22.2 over this period (both, p
