Why the study?
People living with dementia face an increased risk of multiple hospital admissions, making reducing readmission rates a key clinical priority.
What are the determinants of hospital readmission within 180 days and subsequent 1-year mortality in older adults with dementia?
Population
30,527 patients > 65y with dementia and an acute general hospital admission in England
Comparison
Determinants of readmission and post-readmission mortality
Design
Retrospective cohort study using linked electronic health records
Follow-up
180 days of discharge for readmission, and one year of readmission for mortality
Key result
Multiple long-term conditions and male sex were positively associated with hospital readmission within 180 days in older adults with dementia, who experienced an overall readmission rate of 40.5%.

What are the determinants of hospital readmission within 180 days and subsequent 1-year mortality in older adults with dementia?
Multiple long-term conditions are the strongest determinant of hospital readmission within 180 days in older adults with dementia.
Browne et al. (2026) conducted a cohort in dementia (n=30,527). Clinical and demographic factors (e.g., multiple long-term conditions) was evaluated on Readmission to hospital within 180 days of discharge. Multiple long-term conditions and male sex were positively associated with hospital readmission within 180 days in older adults with dementia, who experienced an overall readmission rate of 40.5%.
