An overview of Cochrane systematic reviews for pulmonary rehabilitation interventions in people with chronic obstructive pulmonary disease: a mapping synthesis.

INTRODUCTION

There is a global unmet need for rehabilitation to meet which the World Health Organization, in collaboration with Cochrane Rehabilitation, is developing the Package of Interventions for Rehabilitation with the aim of identifying rehabilitation interventions relevant to a range of key health conditions, including chronic obstructive pulmonary disease (COPD). The purpose of this paper is to describe the best available evidence on pulmonary rehabilitation interventions for people with COPD.

EVIDENCE ACQUISITION

An Overview of Cochrane Systematic Reviews (CSRs). Through the search strategy, COPD-related systematic reviews published from January 2009 to November 2021 were identified. Data were extracted on each reported outcome related to an intervention and judgements about the quality of evidence were made, using the GRADE approach.

EVIDENCE SYNTHESIS

Seventeen reviews were analyzed, for a total of 314 primary studies that included 22,206 participants. CSRs provided information on the effectiveness of rehabilitation on functioning, activity, quality of life, anxiety, depression, mortality, and health care resource utilization.

CONCLUSIONS

Our findings report that comprehensive pulmonary rehabilitation programs and water exercises improve the exercise capacity and quality of life (QoL) in people with COPD. Different exercise modalities, intensities, and settings for different muscle groups, breathing exercises, and counseling can improve exercise capacity, QoL, dyspnea, hospitalizations, and physical activity. It is uncertain whether breathing exercise, low-intensity exercise, neuromuscular electrical stimulation, and psychological intervention have an effect on exercise capacity, dyspnea, QoL, and physical activity. The protocol was registered on OSF (registration DOI: 10.17605/OSF.IO/8A26Q).
