Abstract

This research appraisal, guided by the CASP Randomised Controlled Trial Checklist, critiques a randomised, controlled trial of patient-directed music therapy compared to either noise-cancelling headphones or usual care. This study recruited 373 alert, mechanically-ventilated patients across five intensive care units in the United States. The Music Assessment Tool, administered by a music therapist, facilitated music selection by participants in the intervention group. Anxiety was measured using the VAS-A scale. Sedation exposure was measured by both sedation frequency and by sedation intensity using a daily sedation intensity score. Context for the data was supported by an environmental scan form recording unit activity and by written comments from nurses about the patient's responses to the protocol. Patient-directed music therapy allowed a significant reduction in sedation frequency compared to noise-cancelling headphones and usual care participants. Patient-directed music therapy led to significantly lower anxiety and sedation intensity compared to usual care, but not compared to noise-cancelling headphones.

This is a robust study with clear aims and a detailed description of research methods and follow-up. While no participants were lost to follow-up, not all were included in the analysis: 37% did not have the minimum of two anxiety assessments for comparison and 23% were not included in sedation analysis. While some participants utilised the intervention or active control for many hours-per-day, half the music therapy participants listened for 12 min or less per day and half of the noise-cancelling headphone participants did not appear to use them. While the results suggest that patient-directed music therapy and noise-cancelling headphones may be useful and cost-effective interventions that lead to an overall improvement in anxiety and sedation exposure, these may appeal to a subset of ICU patients. The self-directed use of music therapy and noise-cancelling headphones means these findings may not transfer to sedated or cognitively-impaired patients.

Summary

The aim of this study was to determine whether self-directed, self-initiated music therapy, compared to either noise-cancelling headphones or usual care reduced self-reported anxiety or sedation use in 373 mechanically-ventilated patients. Patient-directed music (PDM) therapy has been shown to divert attention from negative experiences or emotions, reducing the perception of emotional stress.1 PDM is selected with the assistance of a music therapist according to patient preference and

Critique

These findings have relevance for Australian critical care practice. Given the high frequency of anxiety in the critical care environment7 and the known benefits of reducing sedative exposure in the ICU,8 research findings that support non-pharmacological interventions may both improve patient experience and facilitate patients’ participation in their own care. While others have explored the use of music therapy in the ICU, this is the first to use a patient-directed and initiated approach.

    The findings of this study are in line with the findings of our previous studies supporting the notion that listening to natural sounds is a pleasant stimulus and an alternative perceptual focus for patients undergoing mechanical ventilation [13,19]. Similarly, Gullick and Kwan (2015) also indicated that patient-controlled music therapy is a helpful and effective nursing intervention that reduces anxiety in patients undergoing mechanical ventilation [34]. According to the Nguyen et al.’s study, music reduced anxiety scores and some physiologic parameters in children with leukemia who underwent lumbar puncture procedure [35].
