Rate of incident dementia and care needs among older adults with new traumatic brain injury: a population-based cohort study.

ABSTRACT:

Background

The long-term impacts of traumatic brain injury (TBI) in older adults are not well known. Our objective was to describe the association between late-life TBI, incident dementia, and health care needs.

Methods

We conducted a retrospective cohort study using linked health administrative data in Ontario, Canada, and included community-dwelling individuals older than 65 years with a new TBI between Apr. 1, 2004, and Mar. 1, 2020, and up to 17 years of follow-up. People with and without TBI were 1:1 matched on age, sex, and propensity score. We compared rates of incident dementia (≤ 5 yr and > 5 yr), use of publicly funded home care, and admission to a long-term care home, using cause-specific hazard models. We used conditional inference trees to identify subgroups at
