Su, C.P., Lai, H.L., Chang, E.T., Yiin, L., M., Perng, S., J., & Chen, P.W. (2013). A randomized controlled trial of the effects of listening to non-commercial music on quality of nocturnal sleep and relaxation indices in patients in medical intensive care unit. Journal of Advanced Nursing, 69(6), 1377-1389. doi: 10.1111/j.1365- 2648.2012.06130.x
Introduction
The researchers presented a clear and unambiguous purpose statement which was to examine the effects of non-commercial music on quality of sleep and relaxation indices, including heart rate, mean arterial pressure, and respiratory rate in patients in intensive care units. The article began with a straightforward abstract that was organized into the following headings: aim, background, design, methods, findings, conclusions and keywords. The abstract was followed by a logical and illuminating discussion of the phenomena of sleep disturbance, common treatment for sleep disturbance, pharmacology treatment and related adverse reactions, and also provided a rationale for the research study. The researchers briefly discussed the emergence of holistic nursing theory and provided a synopsis of the mind body connection. Inclusive in the discussion was an acknowledgement of the limited mind-body research studies specifically related to music therapy as an intervention to improve sleep. Towards the end of the introduction section, the researchers further clarified their reasoning for this study, stating that music as a method to improve sleep lacks conclusive evidence as a complementary intervention in which this study attempts to remedy by using an objective tool, the polysomnography (PSG).
Literature Review
The literature review which is presented after the introduction and before the methods section consists of 20 peer-reviewed journal articles and is divided into two sections with the following headings: A theoretical base and music and sleep. The theoretical base section provides a logical overview of the psychophysiological theory which describes the biological mechanisms for music’s therapeutic effect. Evidence in this section spans from 1998 to 2012. The music and sleep section includes historical evidence from 1968 and recent primary research from 2003 to 2011. In addition, factors involved in patients sleep disturbances on the ICU unit and sleep patterns of ICU patients in the context of stages of sleep are discussed. The literature review provides a comprehensive basis for the study by the presentation of relevant evidence. It also includes the hypothesis and rationale for the study.
Methodology
The methods section of the article clearly delineates this quantitative experimental, randomized controlled trial study and research methods utilized. The participants were randomly assigned to a control or experimental group with the experimental group receiving therapeutic music intervention, which included 45 minutes of soothing noncommercial music at nocturnal sleep time. Tools utilized for outcome measure were the Verran and Synder-Halpern Sleep Scale (VSH) and a portable wireless polysomnography.
Data Analysis
The data was collected from 28 patients on a medical ICU unit in Taipei, Taiwan. The results were analyzed using PASW for Windows. The researchers who conducted the statistical analysis were not aware of the patient’s group assignment to avoid bias and decrease error. The researchers presented their data analysis in a simple and easy to follow manner. Statistical t-test and x2 tests were used to determine any significant difference in the group characteristics and pre-experimental baseline measures. The findings indicated that no statistical difference was observed. In terms of sleep outcomes, general estimating group differences statistics were employed which revealed a statistical improvement in self-reported sleep quality, measured by VSH sleep scale (p=.012), and in stage N2 (p=.014) and stage N3 (p=.008) as measured by the polysomnography.
Conclusion
The researcher’s conclusions included limitations of the study and the application to nursing practice. The researchers provided a straightforward and uncomplicated discussion of the findings. The researchers concluded based on statistically significant results that listening to sedating music can evoke a considerable autonomic nervous system response and reported that patients in medical ICU benefit from improved quality of sleep if nurses offer a short period of time for listening to music at nocturnal sleep…
