Effect of Music on Pain in Cancer Patients in Palliative Care Service: a Randomized Controlled Study

Effect of Music on Pain in Cancer Patients in Palliative Care Service: a Randomized Controlled Study

Background: Palliative care services can be applied in chronic, life-threatening conditions such as cancer, and provide physical, mental and psychological support to patients worldwide. Purpose: This study aimed to investigate the effect of music on pain, anxiety, comfort and functional capacity of cancer patients received care in a palliative care unit.

Methods: The population of this randomized controlled trial consisted of cancer patients hospitalized in the Palliative Care Service of a Training and Research Hospital between July 2018-July 2019. The sample of the study included 60 patients (30 interventions/30 controls) who met the inclusion criteria. The patients in the intervention group were given a total of six music sessions, ten minutes each with the Turkish classical music in maqams (modes) of their choice (Hejaz or Rast accompanied by an expert tambour (drum) player).

The incidence of chronic diseases and conditions including cancer that require a long-term treatment process and also affect the individual psychological status and quality of life has increased with a high financial burden as a result of relatively prolonged human life under the influence of contemporary medicine. Palliative care services can be applied in chronic, life-threatening conditions such as cancer, and provide physical, mental and psychological support to patients worldwide. Symptoms including pain, constipation, diarrhea, anorexia, dysphagia, nausea and vomiting, dehydration, depression, delirium, and fatigue may demonstrate in cancer patients receiving palliative care, while most of the them have complain of pain. Studies have reported that 30% of cancer patients experienced pain at the diagnosis, 50-70% of them in during treatment period, and 60-80% of them in the terminal period. It was determined in another study that 90% of patients had pain when they were hospitalized in palliative care service, and more than half of them defined the pain severity at 5 and above.

Pharmacological agents were used to manage pain control, as they had rapid effect and were easily applicable. In addition to pharmacological agents, the application of non-pharmacological interventions is important for improving the quality of life and patient comfort and reducing the symptom burden in relieving pain caused by the side effects and methods of treatment in the palliative care cancer patients. Since non-pharmacological methods could reduce pain by applying alone or in combination with drugs, the frequency of use has increased in recent years. Music therapy was used as a non-pharmacological method in many health problems as a traditional treatment and psychosocial interventions. The study was aimed to investigate the effects of music therapy on pain in patients with cancer hospitalized palliative care service. In the current study we tested the hypothesis that palliative care patients' pain management. 1. reduce the rate of pain score. 2. reduce the rate of anxiety scoe. 3. To increase the rate of comfort level. 4. To increase the rate of functional capacity.
