Abstract Background: Music therapy serves as a non-pharmacological intervention for a variety of disorders with promising results. However, the effect of music therapy on improving anxiety, depression, and sleep quality in intensive care unit (ICU) patients remains unclear. This meta-analysis aims to evaluate the effect of music therapy on improving anxiety, depression, and sleep quality in ICU patients, thus providing evidences to support music therapy as a novel complementary alternative therapy. Methods: Randomized controlled trials (RCTs) reporting the efficacy of music therapy on improving anxiety, depression and sleep quality in ICU patients published before January 2022 will be searched in online databases, including the PubMed, the Cochrane Library, Web of Science, Embase, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, VIP Database, and WanFang Database. Literature screening, data extraction, and evaluation of risk of bias will be independently performed by two investigators. Meta-analysis will be performed using Stata 14.0 software. Results: The results of this meta-analysis will be submitted to a peer-reviewed journal for publication. Conclusion: This study will provide reliable evidence-based evidence for the effect of music therapy on anxiety, depression, and sleep quality in ICU patients. Ethics and dissemination: Ethical approval was not required for this study. The systematic review will be published in a peer-reviewed journal, presented at conferences, and shared on social media platforms. OSF Registration number: DOI 10.17605/OSF.IO/EXAZ6.
