Behavioral and psychological symptoms of dementia and adverse patient outcomes post-hospitalization.

Objectives: The occurrence of behavioral and psychological symptoms of dementia (BPSD) are associated with adverse outcomes but have largely been studied in populations outside of acute care. The current study examines (1) the prevalence of BPSD during acute hospitalization and (2) if BPSD are predictive of adverse patient outcomes.

Methods: A secondary analysis of Family-centered Function-focused Care (Fam-FFC) data including 461 patients with dementia/care partner dyads assessed at hospital admission, discharge, 2 months, and 6 months post-discharge, was conducted. Prevalence of BPSD (Neuropsychiatric Inventory-Questionnaire total and Frontal, Hyperactivity, Mood, and Psychosis sub-categories), associations with patient and care partner characteristics, and prediction of adverse events (falls, emergency room [ER] visits, hospitalizations, injury) were examined.

Results: BPSD were highly prevalent (93.9% admission, 86.7% discharge). The most common symptom cluster at admission was Hyperactivity (76.7%) followed by Mood (72.3%) and Psychosis (71.9%), and Frontal (25.9%). Higher admission Hyperactivity was associated with ER admissions at 2 months, higher discharge Hyperactivity was associated with ER admissions and hospitalizations at 2 months, and change in Psychosis was associated with ER admissions at 2 months.

Conclusions: These findings highlight BPSD during hospitalization as potentially modifiable risk factors of adverse outcomes.
