Patients undergoing hemodialysis (HD) face significant challenges; however, non-pharmaceutical interventions hold potential for enhancing their quality of life. This paper evaluates the effects of music therapy on various mental and physiological outcomes in patients undergoing HD. This systematic review and meta-analysis followed the PRISMA 2020 guidelines. A comprehensive database search conducted up to May 21, 2024, identified studies for inclusion based on PICOS criteria. The methodological quality of these studies was assessed using the Cochrane risk-of-bias tool and Review Manager 5.4. For the meta-analysis, R and Stata/SE 15.1 were used, applying a random-effects model in cases of significant heterogeneity, and a fixed-effects model when heterogeneity was minimal. Twenty-four studies involving 1703 participants were analyzed. Music therapy significantly decreased anxiety (SMD: −0.72, 95 % CI: −0.97 to −0.46, I²: 83 %), pain (SMD: −1.22, 95 % CI: −1.68 to −0.75, I²: 93 %), depression (SMD: −0.85, 95 % CI: −1.31 to −0.39, I²: 77 %), stress (SMD: −0.93, 95 % CI: −1.17 to −0.68, I²: 41 %), and adverse reactions associated with HD (SMD: −0.67, 95 % CI: −0.88 to −0.46, I²: 0 %), all showing strong effect sizes ( p < 0.001 for all). However, no significant changes were observed in sleep quality, fatigue, satisfaction with HD, systolic or diastolic blood pressure, heart rate, or finger temperature. A slight reduction in respiration rate ( p = 0.0072) and an increase in oxygen saturation ( p = 0.0056) were noted. While music therapy showed promising results, the notable heterogeneity in pain and anxiety outcomes suggests careful interpretation, although no significant publication bias was detected. Music therapy has demonstrated encouraging outcomes in improving the well-being of patients undergoing HD, particularly in reducing anxiety, pain, and stress. However, due to notable heterogeneity and methodological issues such as small sample sizes and inconsistent blinding, further high-quality research is needed to confirm these findings and establish more robust evidence. Created in BioRender. Gao,Y. (2024) BioRender.com/I00q813 . • Music therapy reduces anxiety, pain, depression, and stress in hemodialysis patients. • Music therapy has a marginal but positive effect on reducing fatigue and adverse reactions. • Small sample sizes, heterogeneity, and inconsistent blinding limit the generalizability of these findings. • High-quality, randomized trials are required to confirm the effect of music therapy on well-being in hemodialysis patients.
