Pulmonary Rehabilitation in Patients with COVID-19—A Protocol for Systematic Review and Meta-Analysis

Introduction: Pulmonary rehabilitation (PR) is a well-established treatment for patients with chronic lung disease; however, its role in patients with COVID-19 has not been systematically studied. We provide a protocol outlining the methods and analyses that will be used in the systematic review. Methods: The methodology of this systematic review protocol has been filed in PROSPERO under the registration number CRD42022301418. Five electronic databases (PubMed, Web of Science, Cochrane Library, EBSCO, and CNKI databases) will be searched from 2019 to 28 July 2022, using pre-determined search terms. Eligibility criteria will be defined using a PICOS framework. Pulmonary function, exercise capacity, and health-related quality of life will be the primary outcomes. Quantitative findings will be narratively synthesized, whilst argument synthesis combined with refutational analysis will be employed to synthesize qualitative data. Results: The results will be presented by both meta-analysis and qualitative analysis. Conclusion: This protocol describes what will be the first systematic review to conduct a worldwide assessment of the effect of PR in patients with COVID-19. Because this is a systematic review and meta-analysis, no ethical approval is needed. The systematic review and meta-analysis will be published in a peer-reviewed journal and disseminated both electronically and in print.
