Content, uptake and adherence of exercise interventions after an acute exacerbation of COPD: a scoping review.

Abstract

Introduction: Pulmonary rehabilitation is underutilised in patients after an acute exacerbation of COPD (AECOPD). Retrieving information regarding the setting, training modalities and the uptake and adherence to exercise interventions for these individuals in a vulnerable state could potentially guide future research.

Aim: To provide a comprehensive review of the existing literature on the content, uptake and adherence of different exercise interventions for patients after an AECOPD.

Methods: Eight different databases were searched for 1) patients experiencing an AECOPD and 2) performing any form of exercise intervention. Information on content, uptake and adherence was collected and the Consensus on Exercise Reporting Template (CERT) checklist was performed for each included record.

Results: 59 distinct interventions were identified between 1998 and 2023 including a total of 9238 patients. All studies included patients requiring hospitalisation for the AECOPD, four studies additionally included patients not requiring hospitalisation for the AECOPD. Nine different settings were identified, with the majority of studies conducted in an inpatient setting (n=26) and including whole-body and strength exercises. The overall uptake was mentioned in 38 (62%) studies and was 70% with a 13% dropout rate. No paper reported the full CERT checklist. Adherence was defined a priori in 16 (27%) studies, with the most common definition being attendance of >80% of sessions.

Conclusion: Studies properly reporting on the uptake and adherence of well-described interventions, including information regarding fidelity, are needed to further investigate suitable programmes for patients experiencing an AECOPD.
