Hospital Readmission in Dementia Care, Prevalence, Associated Risks, and Interventions to Reduce Avoidable Readmissions, a Narrative Synthesis of Literature Reviews

OBJECTIVES/DESIGN: This narrative synthesis of reviews consolidates readmission risk factors for patients with dementia to establish the most significant risks and explore interventions to reduce readmissions. METHODS: A narrative synthesis of reviews was conducted. Six electronic databases were searched in April 2025. Of the 304 articles initially identified, a total of 14 articles met the full inclusion criteria and were included. RESULTS: Thirty-day readmission rates across the reviews ranged from 16% to 30% in people with dementia and 10% to 17% for those without. Risk factors for 30-day readmission were comorbidities, living alone, ethnic minorities, and behavioral and psychological symptoms of dementia. Definitions and comparators varied across reviews. Organizational risks were ineffective discharge planning and poor communication across services. Readmission reduction focused on case management, improved communication, and interdisciplinary care. CONCLUSIONS AND IMPLICATIONS: Rates of readmission for people with dementia appeared higher. Personal characteristics, comorbidities, and organizational influences are associated with readmission. Some interventions were found to reduce readmissions, such as case management, but the heterogeneity in the studies makes it difficult to assess where to focus services. Developing a deeper understanding of persons most at risk of readmission will facilitate interventions for those most at risk.
