Complementary Musical Intervention for Patients in Palliative Care in Spain: A Randomized Controlled Trial

Abstract

Background: Patients with advanced cancer often endure a heavy burden of symptoms, both in quantity and intensity. Complementary therapies offer potential relief in this challenging scenario. Increasing the number of randomized controlled trials provides a unique opportunity to generate rigorous data, which can be used to establish causal relationships and evaluate interventions; hence, nurses can strengthen evidence-based practices, leading to better patient outcomes and quality of care. Our study aimed to evaluate the impact of a 7-day pre-recorded music intervention on cancer symptoms and satisfaction in advanced-stage cancer patients receiving palliative care at home. Methods: This multicenter, double-blind, randomized, controlled clinical trial involved 80 Spanish cancer patients receiving palliative care at home, and was conducted from July 2020 to November 2021. The intervention group (n = 40) received self-selected pre-recorded music for 30 min daily over 7 days. The control group (n = 40) received pre-recorded basic health education sessions of equal duration and frequency. Symptoms and patient satisfaction were assessed before and after the intervention using the Edmonton Symptom Assessment System and the Client Satisfaction Questionnaire, respectively. Results: Comparing the intervention with the control group, significant improvements were observed in various symptoms: total symptom burden (p < 0.001), pain (p = 0.001), fatigue (p = 0.007), depression (p = 0.001), anxiety (p = 0.005), drowsiness (p = 0.006), appetite (p = 0.047), well-being (p ≤ 0.001), and sleep (p < 0.001); additionally, patient satisfaction was higher in the intervention group (p < 0.001). Conclusions: The 7-day pre-recorded music intervention reduced both physical and psychological symptoms in advanced-stage cancer patients receiving home-based palliative care, demonstrating significant alleviation of overall symptom burden and increased satisfaction with healthcare
