DOES LISTENING TO LIVE MUSIC DURING HEMODIALYSIS SESIONS AFFECT THE QUALITY OF LIFE?

Abstract Background and Aims Patients with chronic kidney disease on hemodialysis (HD) treatment have a health-related quality of life (HRQoL) lower than the reference values of the Spanish population. Previous studies have shown through music therapy reduce levels of pain, anxiety and depression in chronic kidney disease patients on hemodialysis. This study presents an intervention with classical music performed live during HD sessions. It is the first time to study the effect of classical music heard live on HRQL. Method Randomized clinical trial by groups. 90 patients agreed to participate. They were randomized into an intervention group (IG) and a control group (CG). The IG listened to 30/45 minutes of live classical music in two of the three weekly HD sessions for 1 month. The CG followed his usual treatment. Different individual scales of the quality of life test in kidney diseases (KDQOL-SF) were analyzed, in two times, baseline (Start) and after (End) the musical intervention in both groups. The analysis was performed using a mixed linear regression model for repeated measures with independent variables (age, sex, months in HD, Kt/v, Hemoglobin (Hb)) and dependent variables (individual KDQOL-SF scale scores). Results The CG sample included 43 patients with a mean age of 75.8 years; 22 women (51%); mean Kt/v 1.53; mean Hb 11.5 and mean time on HD 60.46 months. The GI sample included 47 patients with a mean age of 73.53 years; 18 women (38%); mean Kt/v 1.47; mean Hb 11.3 and mean time on HD 63.34 months. The results show that after the intervention, IG vs CG increased the mean score (pm) in all the scales significantly. The End time and GI interaction showed a mean score increase of 15.78 (p <0.001) for the Symptoms/problems scale; 14.96 (p <0.001) scale Effects of kidney disease; 16.36 (p <0.001) on the Kidney disease burden scale; 14.78 (p <0.001) on the Sleep scale; 25.46 (p <0.001) on the Vitality scale; 29.57 (p <0.001) on the Emotional well-being scale; 41.92 (p <0.001) on the Pain scale and 23.39 (p <0.001) on the General Health scale. Conclusion Live classical music intervention during hemodialysis sessions improves self-perceived HRQL in patients with chronic kidney disease on HD
