Effect of music intervention during hemodialysis: a comprehensive meta-analysis.

Abstract

Aggravating disease and the accompanying increase in the frequency of hemodialysis interventions worsen the quality of life of patients leading to poor physical and psychological outcomes. Music-based interventions have been suggested to improve both the physical and psychological prognoses for patients undergoing hemodialysis. Two meta-analyses on the impact of music-based interventions on anxiety in patients undergoing hemodialysis failed to evaluate the impact of these interventions on other physiological outcomes. Therefore, in this study, we gather evidence on the effects of music-based interventions on physical and psychological outcomes in patients with chronic kidney disease undergoing hemodialysis. To determine the influence of music-based interventions on anxiety, pain, heart rate, and blood pressure (systolic, diastolic) in patients with chronic kidney disease undergoing hemodialysis, we performed a systematic literature search adhering to PRISMA guidelines on the EMBASE, CENTRAL, Scopus, and MEDLINE academic databases. We performed meta-analyses to consolidate the evidence on the influence of music-based interventions on the physical and psychological outcomes of patients with chronic kidney disease undergoing hemodialysis. From 1,402 studies, we found eight eligible studies with 597 (264 women, 287 men) patients with chronic kidney disease undergoing hemodialysis (mean age, 56.9 ± 10.8 years). Among these patients, 298 received the music-based intervention and 299 were included as controls. Our meta-analysis revealed a small-to-medium effect of the music-based intervention to reduce pain levels (Hedge s g, -0.75), anxiety (-0.16), heart rate (-0.15), and systolic (-0.14) and diastolic blood pressure (-0.11) in patients with chronic kidney disease receiving hemodialysis as compared to the values of the same variables in the control group. The evidence from our analyses supports the beneficial impact of music-based interventions to alleviate anxiety and pain, and to reduce heart rate and blood pressure in these patients.
