Predictors of premature discontinuation and prevalence of dropouts from a pulmonary rehabilitation program in patients with chronic obstructive pulmonary disease

To date, very little is known about the risk factors that contribute to premature discontinuation (dropout) from pulmonary rehabilitation (PR) in patients with chronic obstructive pulmonary disease (COPD). We examined prevalence and predictors of premature discontinuation in patients who participate...

description To date, very little is known about the risk factors that contribute to premature discontinuation (dropout) from pulmonary rehabilitation (PR) in patients with chronic obstructive pulmonary disease (COPD). We examined prevalence and predictors of premature discontinuation in patients who participated in an eight week PR program. We analyzed a prospectively maintained data-base of patients with COPD who attended a PR program from 2013 to 2019. We included patients 40 years or older with forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) ratio less than 0.7. Subjects were assigned completers or non-completers based on whether they completed the 8-week PR program. Quality of life was measured using the St-George's Respiratory Questionnaire (SGRQ), anxiety using the Anxiety Inventory for Respiratory disease (AIR), dyspnea using the modified Medical Research Council (mMRC) scale, and exercise capacity using the Incremental Shuttle Walk Test (ISWT). Nine hundred nighty three COPD patients (mean age = 70.82 years, FEV1 = 59.21% predicted, 51% male) entered the PR program. Of these, 259 (26%) discontinued PR prematurely and 139 (53%) were male. Compared with completers, non-completers had elevated symptoms of dyspnea and anxiety, had reduced exercise tolerance, were younger, and had poorer quality of life at entry (all p
