The effect of preferred music on sleep quality among patients after coronary artery bypass surgery

The aim of this study was to examine the effect of preferred music on sleep quality of patients after coronary artery bypass surgery (CABG). Background. Sleep disorder is common among patients undergoing coronary artery bypass surgery that can also affect other postoperative outcomes. This study was a quasi-experimental trial in which 70 patients who were undergoing coronary artery bypass surgery were recruited using convenience sampling method and assigned into the experimental and control group. Patients in experimental group listened to their preferred music by MP3 player for 20 minutes during 4 consecutive days، while patients in control group received only routine care. The patients’ sleep quality was measured before and after the intervention by means of Pittsburgh sleep quality inventory. Data were analyzed by SPSS، version 16، and descriptive and inferential statistical were used to report the findings. There was no statistically significant difference in sleep quality، before and after intervention in experimental and control groups. Conclusion. Music did not have effect on sleep quality among patients undergoing coronary artery bypass surgery، but the study can be reproduced with some modifications (change in intervention time and period and targeted selection of patients) in future studies.
