OBJECTIVES: Characterize the precipitants and outcomes of psychiatric hospitalizations among patients enrolled in a comprehensive dementia care program and identify factors associated with discharge to higher-level residential setting. DESIGN: Retrospective cohort study. SETTING: UCLA Alzheimer's and Dementia Care Program. PARTICIPANTS: Patients hospitalized at the UCLA Resnick Neuropsychiatric Hospital (NPH). MEASUREMENTS: Precipitating reasons for hospitalization, patient demographic and clinical characteristics, hospitalization-level characteristics, and caregiver relationship. Discharge to higher-level residential settings (e.g., assisted living, nursing home). Change in scheduled Central Nervous System (CNS)-active medications (antipsychotics, antidepressants, and sedative/hypnotics). RESULTS: There were 180 psychiatric hospitalizations among 150 patients, with a median age of 79 years (IQR, 73-85) at admission and MMSE score of 17 (IQR, 12-24) at first hospitalization. Agitation was the most common precipitating reason for hospitalization (n = 127, 71%). Median length of stay was 14 days (IQR, 9-26); 54 (30%) resulted in discharge to a higher-level residential setting. Agitation as the precipitant for hospitalization (aOR, 4.7; 95% CI, 1.7-12.9, p = 0.003) and male sex (aOR, 2.3; 95% CI, 1.0-5.5, p = 0.049) were associated with higher odds of discharge to a higher-level setting. Most hospitalizations resulted in no change in the number of scheduled CNS-active medications (e.g., 69% had no change in the number of scheduled antipsychotics), while escalation occurred in 19%-28%, depending on medication class. CONCLUSION: Psychiatric hospitalization precipitated by agitation or involving male patients was often followed by transition to higher-level residential care. Future studies should evaluate whether earlier outpatient psychiatry involvement and proactive placement planning can reduce hospitalization and subsequent placement changes.
