Music session interventions were found to reduce anxiety among patients admitted to the intensive care unit (ICU), according to a systematic review and meta-analysis in the Journal of Clinical Nursing.
Reviewing 25 studies, music was found to significantly reduce anxiety scores overall, regardless of the system of measurement, reported Öznur Erbay Dalli, RN, MSc, PhD, of Bursa Uludag University in Turkey, and colleagues.
Music also significantly reduced anxiety scores versus standard care, including prescribed drugs or care protocol as part of usual treatment. This was comparable to noise-reducing methods. In the ICU, noise is an important driver of stress, the authors explained.
Throughout history, music has been used as one of the “proven non-pharmacological tools” to reduce anxiety, depression, and pain and to increase patient comfort, they added.
Dr Dalli told MedPage Today that ICU nurses and other healthcare workers may complement their daily routine care with music to reduce the anxiety of ICU patients and to avoid the side effects of medications, which are commonly used for treating anxiety.
No effect on diastolic blood pressure, respiration rate, or heart rate due to the music was seen. Subgroup analysis showed that multiple sessions produced better outcomes.
The researchers searched for studies published up to January 2022. All of the 25 included studies were randomised controlled trials or controlled clinical trials in 9 different countries with 1751 participants in total. Average age was 59 and 57% were male.
Of the anxiety assessment tools, the State-Trait Anxiety Inventory was the most commonly used tool (9 studies), followed by the Fear, Anxiety, and Stress Scale (4 studies) and the Visual Analogue Scale for Anxiety (2 studies).
Music interventions were mostly recorded music, although one study included a harp being played live. Music was used during rest times in most studies, though in four studies, music was used during specific procedures, like catheterisation or endotracheal suctioning.
No side effects were reported in the studies examined, but some patients objected to the choice of music, something which could be addressed by consultation with family members.
Limitations to the study included the fact that it was “difficult or impossible” to blind participants and other healthcare personnel involved in the study due to the nature of the intervention, which could lead to a “high risk of performance bias,” the authors noted. Additionally, the range of protocols and evaluation techniques used among the studies resulted in high heterogeneity.
Publication bias was possible due certain studies having small sample sizes, and a lack of available data.
