The Effect of Music Therapy on Comfort, Pain and Anxiety in Patients With Bone Marrow Aspiration and Biopsy: A Randomized Controlled Research

Objectives: This study was conducted to determine the effect of music therapy on the pain, anxiety, and comfort levels of patients who underwent bone marrow aspiration and biopsy.

Methods: This research was conducted as a randomized controlled study in the hematology polyclinic of a university hospital. Music therapy will used with the intervention group throughout the procedure. During data evaluation, paired t-test, independent t-test and effect size will used. The sample group was calculated based on the sample groups of other studies in the literature (Çelebi et al., 2020; Özdemir et al., 2019). According to the preliminary power analysis results using the G.Power 3.1.9 program, the sample size was calculated at 80% power, at medium effect size at 5% alpha value. According to the analysis results, the sample size per group was calculated as 30. However, since there was 10% probability that some patients may drop, the sample size for the study was recalculated as 66 (Experimental Group: 33, Control Group: 33).The patients will informed about using music. In addition, it will explained that they could adjust the sound levels and that they should report when they are disturbed by the tone. Music continued throughout the process.
