Effect of respiratory rehabilitation training on elderly patients with COVID-19: A protocol for systematic review and meta-analysis

BACKGROUND: Patients with the Corona Virus Disease 2019 (COVID-19) often see their respiratory, physical, and psychological functions impaired to varying degrees, especially for the elderly patients. Timely respiratory rehabilitation intervention for such patients may improve their prognoses. However, its relative effectiveness has not been proved. Therefore, this study is purposed to determine the effect of respiratory rehabilitation on elderly patients with COVID-19. METHODS: This study will search the following electronic databases: Embase, MEDLINE, PubMed, Cochrane Library, China national knowledge infrastructure database, Wan Fang database, Chinese Science and Technology Periodical Database, and Chinese Biomedical Literature Database, with the retrieval period running from their inception to August 2020. All randomized controlled trials of respiratory rehabilitation training on elderly patients with COVID-19 are collected, and the data are selected and extracted independently according to the pre-designed inclusion/exclusion criteria. Cochrane bias risk assessment tool is used to evaluate the method quality and bias risk. All data analyses will be implemented by using Revman5.3 and Stata14 software. RESULTS: This study will make a high-quality and comprehensive evaluation of the efficacy of respiratory rehabilitation training on elderly patients with COVID-19. CONCLUSION: The conclusions of this systematic review will deliver more convincing evidence. ETHICS AND DISSEMINATION: The private information collected from individuals will not be published. And this systematic review will also not involve impairing the participants’ rights. Ethical approval is not required. The results may be published in a peer-reviewed journal or disseminated in relevant conferences.
