ContextMultimodal analgesic approaches are recommended for intensive care unit (ICU) pain management. Although music is known to reduce pain in acute and chronic care settings, less is known about its effectiveness in the adult ICU.ObjectivesDetermine the effects of music interventions on pain in the adult ICU, compared with standard care or noise reduction.MethodsThis review was registered on PROSPERO (CRD42018106889). Databases were searched for randomized controlled trials of music interventions in the adult ICU, with the search terms ["music*" and ("critical care" or "intensive care")]. Pain scores (i.e., self-report rating scales or behavioral scores) were the main outcomes of this review. Data were analyzed using a DerSimonian-Laird random-effects method with standardized mean difference (SMD) of pain scores. Statistical heterogeneity was determined as I2 > 50% and explored via subgroup analyses and meta-regression.ResultsEighteen randomized controlled trials with a total of 1173 participants (60% males; mean age 60 years) were identified. Ten of these studies were included in the meta-analysis based on risk of bias assessment (n = 706). Music was efficacious in reducing pain (SMD -0.63 [95% CI -1.02, -0.24; n = 10]; I2 = 87%). Music interventions of 20-30 minutes were associated with a larger decrease in pain scores (SMD -0.66 [95% CI -0.94, -0.37; n = 5]; I2 = 30%) compared with interventions of less than 20 minutes (SMD 0.10 [95% CI -0.10, 0.29; n = 4]; I2 = 0%). On a 0-10 scale, 20-30 minutes of music resulted in an average decrease in pain scores of 1.06 points (95% CI -1.56, -0.56).ConclusionMusic interventions of 20-30 minutes are efficacious to reduce pain in adult ICU patients able to self-report.Copyright © 2019 American Academy of Hospice and Palliative Medicine.
