Intervention study to verify the effect of live classic music during hemodialysis on the quality of life of patients with chronic kidney disease

Abstract

Introduction and objective: Music has been closely linked to medicine since ancient times, and has brought numerous benefits to the health of patients. Patients with chronic kidney disease (CKD) undergoing hemodialysis (HD) generally have a health-related quality of life (HRQL) lower than the reference values ​​of the general population. The objective of the present study is to verify if the intervention of classical music live and "in situ" during the treatment of HD has effects on the HRQoL of the patients.

Materials and methods: A prospective, group-randomized intervention study of 4 weeks' duration was carried out in patients with chronic kidney disease undergoing hemodialysis. Descriptive variables are included for data analysis: age, sex, months in treatment, Kt/V, hemoglobinand albumin. Result variable: HRQL, measured with the Kidney Diseasse health questionnaire Quality of life (KDQOL-SF) before and after the musical intervention.

Results: Patients participated in 2 groups, the intervention group and the control group. The analysis of the results shows that the intervention group improved their quality of life compared to the initial measurement. The difference between the pre and post time of the intervention group with respect to the control group increased the mean score (pm) in all the scales significantly, except in the Work situation, Sexual function and Social support scales. The most important results were given on the Symptoms/problems scale with an increase of 15.78 (p < 0.001) pm; in scale Effects of kidney disease with an increase of 14.96 (p < 0.001) pm; in scale Burden of kidney disease with an increase of 16.36 (p < 0.001) pm; on the Dream scale with an increase of 14.78 (p < 0.001) pm; on the Vitality scale with an increase of 25.46 (p < 0.001) pm; on the Emotional well-being scale with an increase of 29.57 (p < 0.001) pm; on the Pain scale with an increase of 41.92 (p < 0.001) pm and on the General Health scale with an increase of 23.39 (p < 0.001) pm.

Conclusion: Intervention with live music and on-site while receiving hemodialysis treatment improves self-perceived HRQL in patients with chronic kidney disease.
