Effects of music therapy on anxiety of patients with breast cancer after radical mastectomy: a randomized clinical trial.

AIM: This paper is a report of a clinical trial of the effects of music therapy on anxiety of female breast cancer patients following radical mastectomy. BACKGROUND: There is insufficient evidence on the effects of music therapy on state anxiety of breast cancer patients following radical mastectomy. METHODS: A Hall's Core, Care, and Cure Model-based clinical trial was conducted in 120 female breast cancer patients from March to November 2009. A randomized controlled design was utilized. The patients were randomly allocated to the experimental group (n = 60) received music therapy in addition to routine nursing care, and the control group (n = 60) only received routine nursing care. A standardized questionnaire and the State Anxiety Inventory were applied. The primary endpoint was the state anxiety score measured at pretest (on the day before radical mastectomy) and at three post-tests (on the day before patients were discharged from hospital, the second and third time of admission to hospital for chemotherapy respectively). RESULTS: The pretest score revealed that the majority of the patients had a moderate level (77·5%) and 15% had severe level of state anxiety. The repeated-measure ancova model analysis indicated that the mean state anxiety score was significantly lower in the experimental group than those in the control group at each of the three post-test measurements. The mean difference between the experimental and control group together with 95% confidence intervals were -4·57 (-6·33, -2·82), -8·91 (-10·75, -7·08) and -9·69 (-11·52, -7·85) at the 1st post-test, 2nd post-test and 3rd post-test respectively. CONCLUSION: Music therapy is found to have positive effects on decreasing state anxiety score.

Effects of music therapy on depression and duration of hospital stay of breast cancer patients after radical mastectomy.

BACKGROUND: Breast cancer remains the most important cancer among women worldwide. The disease itself and treatment may have a profound impact on the patients' psychological well being and quality of life. Depression is common in breast cancer patients and affects the therapeutic effects as well as prolongs the duration of hospital stay. However, few studies reported the effectiveness of music therapy on depression and duration of hospital stay of female patients with breast cancer after radical mastectomy. METHODS: One hundred and twenty subjects were recruited to this clinical trial and randomly allocated to two groups. The experimental group (n = 60) received music therapy on the basis of routine nursing care, whereas the control group (n = 60) only received the routine nursing care. The whole intervention time was from the first day after radical mastectomy to the third time of admission to hospital for chemotherapy. Data of demographic characteristics and depression were collected by using the General Questionnaire and Chinese version of Zung Self-rating Depression Scale (ZSDS) respectively. One pre-test (the day before radical mastectomy) and three post-tests (the day before discharge from hospital, the second and third admission to hospital for chemotherapy) were utilized. Duration of hospital stay was calculated from the first day after radical mastectomy to the day of discharged from hospital. RESULTS: The mean depression score of all subjects was 37.19 ± 6.30. Thirty-six cases (30%) suffered from depression symptoms, with 26 (72.2%) mild depression cases, 9 (25.0%) moderate depression cases, and 1 (2.8%) severe depression case. After music therapy, depression scores of the experimental group were lower than that of the control group in the three post-tests, with significant differences (F = 39.13, P < 0.001; F = 82.09, P < 0.001). Duration of hospital stay after radical mastectomy of the experimental group ((13.62 ± 2.04) days) was shorter than that of the control group ((15.53 ± 2.75) days) with significant difference (t = -4.34, P < 0.001). CONCLUSIONS: Music therapy has positive effects on improving depression of female patients with breast cancer, and duration of hospital stay after radical mastectomy can be reduced. It is worthy of applying music therapy as an alternative way of nursing intervention in clinical nursing process of caring female patients with breast cancer.

Effects of music therapy on pain among female breast cancer patients after radical mastectomy: results from a randomized controlled trial.

Music therapy has been used in multiple health care settings to reduce patient pain, anxiety, and stress. However, few available studies have investigated its effect on pain among breast cancer patients after radical mastectomy. The aim of this study was to explore the effects of music therapy on pain reduction in patients with breast cancer after radical mastectomy. This randomized controlled trial was conducted at the Surgical Department of Oncology Center, First Affiliated Hospital of Xi'an Jiaotong University from March to November 2009. A total of 120 breast cancer patients who received Personal Controlled Analgesia (PCA) following surgery (mastectomy) were randomly allocated to two groups, an intervention group and a control group (60 patients in each group). The intervention group accepted music therapy from the first day after radical mastectomy to the third admission to hospital for chemotherapy in addition to the routine nursing care, while the control group received only routine nursing care. Pain scores were measured at baseline and three post-tests using the General Questionnaire and Chinese version of Short-Form of McGill Pain Questionnaire. The primary endpoint was the change in the Pain Rating Index (PRI-total) score from baseline. Music therapy was found to reduce the PRI-total score in the intervention group significantly compared with the control group with a mean difference (95% CI) of -2.38 (-2.80, -1.95), -2.41 (-2.85, -1.96), and -1.87 (-2.33, -1.42) for the 1st, 2nd, and 3rd post-tests, respectively. Similar results were found for Visual Analogue Scale (VAS) and Present Pain Intensity (PPI) scores. The findings of the study provide some evidence that music therapy has both short- and long-term positive effects on alleviating pain in breast cancer patients following radical mastectomy.
