Preventable adverse events and related outcomes among people with dementia in hospital settings: scoping review
Lucía Catalán, Lucía Catalán, Déborah Oliveira, Déborah Oliveira. Aging & Mental Health, 2025-04-06
Topic: Risk, prevention and care in population studies
Of the 1976 retrieved studies, 16 were included. Adverse events were more frequent among people with dementia compared to people without dementia. In studies with non-surgical and surgical patients, the most frequently reported were falls, delirium, and infections, while in studies exclusively conducted with surgical patients, these were postoperative delirium, infections, and other complications. The link between adverse events and negative outcomes was explored in only three studies and indicated that those who experienced adverse events had longer hospital stays, higher risk of mortality, and higher readmission rates within 90 days. Although we were unable to establish a direct link between adverse events and hospital outcomes due to the exploratory nature of this review, the findings suggest that mitigating such events could help improve outcomes among hospitalized people with dementia. Hospital safety measures appear to be insufficient to protect this group.

Key findings
- Of the 1976 retrieved studies, 16 were included.
- Adverse events were more frequent among people with dementia compared to people without dementia.
- In studies with non-surgical and surgical patients, the most frequently reported were falls, delirium, and infections, while in studies exclusively conducted with surgical patients, these were postoperative delirium, infections, and other complications.
- The link between adverse events and negative outcomes was explored in only three studies and indicated that those who experienced adverse events had longer hospital stays, higher risk of mortality, and higher readmission rates within 90 days.
- Although we were unable to establish a direct link between adverse events and hospital outcomes due to the exploratory nature of this review, the findings suggest that mitigating such events could help improve outcomes among hospitalized people with dementia.
Why it matters
This scoping review found that adverse events such as falls, delirium and infections were more frequent among hospitalised people with dementia than those without. Only three studies explored links to outcomes, and the review could not establish a direct link, but suggests mitigating such events could help improve outcomes.
