ABSTRACT
Pulmonary rehabilitation [PR] has inconsistent effects on health-related quality of life [HRQL] in patients with chronic lung diseases. We evaluated the effect of PR on HRQL outcomes using the 36-item short form of the medical outcomes [SF-36]. We retrospectively reviewed the files of all patients who completed PR in 2010, 2011, and first half of 2012. We collected information on demographics, symptoms, pulmonary function tests, 6-minute walk tests [6-MWT], and responses on the SF-36 survey, including the physical component score [PCS] and mental component score [MCS]. The study included 19 women and 22 men. The mean age was 69.8 +/- 8.5 years. The diagnoses included chronic obstructive pulmonary disease [COPD; n = 31], asthma [n = 3], interstitial lung disease [n = 5], and obstructive sleep apnea [OSA; n = 2]. The mean forced expiratory volume-one second [FEV1] was 1.16 +/- 0.52 L [against 60.5 +/- 15.9% of predicted value]. There was a significant improvement in 6-MWT [P < 0.0001]. The PCS improved post-PR from 33.8 to 34.5 [P = 0.02]; the MCS did not change. These patients had low SF-36 scores compared to the general population; changes in scores after PR were low. These patients may need frequent HRQL assessment during rehabilitation, and PR programs should consider program modification in patients with small changes in mental health
