Avoidable Hospitalizations in Persons with Dementia: a Population-Wide Descriptive Study (2000-2015).

BACKGROUND

Whether avoidable hospitalizations in community-dwelling persons with dementia have decreased during primary care reforms is unknown.

METHODS

We described the prevalence and trends in avoidable hospitalizations in population-based repeated yearly cohorts of 192,144 community-dwelling persons with incident dementia (Quebec, 2000-2015) in the context of a province-wide primary care reform, using the provincial health administrative database.

RESULTS

Trends in both types of Ambulatory Care Sensitive Condition (ACSC) hospitalization (general and older population) and 30-day readmission rates remained constant with average rates per 100 person-years: 20.5 (19.9-21.1), 31.7 (31.0-32.4), 20.6 (20.1-21.2), respectively. Rates of delayed hospital discharge (i.e., alternate level of care (ALC) hospitalizations) decreased from 23.8 (21.1-26.9) to 17.9 (16.1-20.1) (relative change -24.6%).

CONCLUSIONS

These figures shed light on the importance of the phenomenon, its lack of improvement for most outcomes over the years, and the need to develop evidence-based policies to prevent avoidable hospitalizations in this vulnerable population.
