Abstract
INTRODUCTION: Pulmonary rehabilitation (PR) is a key component in the management of chronic obstructive pulmonary disease (COPD). There is no strong evidence on the optimal duration of PR programmes. The aim of this study is to determine whether an 8-week PR programme is equivalent to a 12-week PR programme in people with COPD. METHODS AND ANALYSIS: This study will be a prospective, multisite, randomised controlled, equivalence trial with assessors blinded to group allocation and intention-to-treat analysis. 72 participants with COPD will be recruited and randomised to either a supervised, twice weekly for 8 weeks or a 12-week PR programme of exercise training and education. PRIMARY OUTCOME: endurance shuttle walk test. SECONDARY OUTCOMES: will include St George's Respiratory Questionnaire, 6-min walk distance, COPD assessment test, Hospital Anxiety and Depression Scale, physical activity monitoring and hospital admissions at 6 months and 12 months. Repeated measures analysis of variance will be used to analyse differences between the groups for all outcomes. ETHICS AND DISSEMINATION: Ethics approval was gained from all participating sites. Results of the trial will be submitted for publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: ACTRN12616001586404.
