Music therapy reduces delirium incidence in adult ICU patients
Music therapy significantly reduced the incidence of delirium in adult ICU patients (RR = 0.49; 95% CI: 0.40-0.60; p < 0.001). The meta-analysis of 15 RCTs involving 1,552 patients also showed improvements in sleep quality, anxiety, and depression.

Music therapy reduces delirium incidence in adult ICU patients The current body of evidence comprises 1 study and 1 meta-analysis. EvidenceHub rates the overall confidence at 49/100 (low).
The Claim
Music therapy reduces delirium incidence in adult ICU patients
This conclusion is most relevant to: Adult ICU patients (1,552 patients from 15 RCTs).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Effects of music therapy on delirium, clinical outcomes, and psychological and sleep outcomes in adult ICU patients: a systematic review and meta-analysis. (Frontiers in medicine, 2026) —
How It Works
The proposed biological pathway:
- ▸Music therapy reduces stress and anxiety
- ▸Modulates autonomic nervous system activity
- ▸Improves sleep architecture and reduces arousal
- ▸Result: Lower risk of delirium and improved psychological outcomes
Who Might Benefit
Evidence fit by population:
- ▸Adult ICU patients (1,552 patients from 15 RCTs)
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Heterogeneity in some secondary outcomes
- ▸Lower certainty in some secondary outcomes (e.g., hospital length of stay, pain)
- ▸Larger multicenter trials needed before routine integration into protocols
Frequently Asked Questions
What is the effect of music therapy on delirium in ICU patients?▼
Music therapy reduces delirium incidence by about 51% (RR = 0.49) based on a meta-analysis of 15 RCTs.
Does music therapy improve sleep in ICU patients?▼
Yes, objective acute sleep quality (measured by RCSQ) was significantly enhanced (SMD = -0.62; p < 0.001).
Is music therapy effective for anxiety and depression in ICU patients?▼
Yes, anxiety was significantly relieved (SMD = -0.79; p = 0.02) and depression symptoms improved (SMD = -1.30; p < 0.001).
What are the limitations of this study?▼
Limitations include heterogeneity in some outcomes, lower certainty for hospital length of stay and pain, and the need for larger multicenter trials.
