Attendance at pulmonary rehabilitation classes: An exploration of demographic, physiological and psychological factors that predict completion of treatment

Pulmonary rehabilitation (PR) is an effective treatment for people with chronic obstructive pulmonary disease (COPD). However, uptake and adherence to rehabilitation is poor and non-adherence is associated with poorer clinical outcomes. This study investigated the factors that might predict an individual completing his/her PR programme. Demographic, physiological and psychological data were collected from routine assessment information. Non-completers (N = 213) who dropped out after initial assessment were compared with completers (N = 438) who attended all 6 weeks of PR programme. Regression analysis indicated that smoking status was the strongest predictor for completing PR programme, that is, ex-smokers were 2.6 times (95% confidence interval (CI) = 1.7–3.9) and those who had never smoked were 2.5 times (95% confidence interval (CI) = 1.1–5.7) more likely to complete in comparison with those who were current smokers. Scoring better on psychological well-being measures (odds ratio = 1.6; 95% CI = 1.2–1....
