# Effectiveness of Music Therapy for Delirium in Acute Hospital Settings: A Scoping Review

## TL;DR

This review explores how music therapy can help older adults with delirium in hospitals by improving behavior, emotions, and recovery.

## Contribution

This is the first scoping review focusing specifically on music therapy for delirium in acute hospital settings.

## Key findings

- Music therapy may reduce the incidence or severity of delirium in older adults.
- Music interventions can improve patient-staff interactions and reduce distress during recovery.
- Music therapy supports emotional regulation and enhances patient experience in acute care.

## Abstract

Background: Music therapy is a non-pharmacological psychosocial intervention that is increasingly recognised for its role in supporting older adults in acute hospital settings. Engagement with music, whether through passive listening, preferred recorded music, live music, or creative music therapy, has been linked to improvements in behavioural, cognitive, and emotional outcomes during episodes of delirium. Although there are reviews on non-pharmacological approaches to delirium, few have focused specifically on music therapy within acute hospital environments. Methods: This scoping review examined the evidence relating to music-based interventions for older adults who are experiencing delirium or who are at risk of delirium in acute care settings. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA ScR). Four electronic databases were searched systematically, namely, CINAHL, Medline, PsycINFO and Embase. Results: Seven primary research studies published between 2004 and 2024 met the inclusion criteria. A narrative synthesis approach was used to summarise the data. Three themes were identified. The first relates to the extent to which music therapy may reduce the incidence or severity of delirium or other related behaviours in acute hospital settings. The second relates to the potential for music-based interventions to support clinical practice by improving interaction between patients and staff and reducing distress during recovery and enhancing physical recovery. The third relates to the impact of music therapy on emotional regulation, engagement, cooperation with care, and overall patient experience. Conclusion: Music therapy shows promise as a person-centred, safe, and low-cost intervention that may enhance wellbeing and support delirium care for older adults in acute hospital settings. Further high-quality studies are needed to strengthen the evidence base and guide practice.
