This study aimed to examine the institutionalization rate in patients with dementia in Taiwan, identify the predictors of institutionalization, and conduct a mediation analysis of caregiver burden between neuropsychiatric symptoms and institutionalization. We analyzed data from a retrospective cohort registered in dementia collaborative care (N = 518). The analyses applied univariate and multivariate Cox proportional hazard regression with Firth’s penalized likelihood to assess the relationship between each predictor at entry and institutionalization for survival analysis. Thirty (5.8%) patients were censored due to institutionalization after a median follow-up of one-and-a-half years. Neuropsychiatric symptoms, loss of walking ability, and living alone predicted institutionalization. Caregiver burden may partially mediate the effects of neuropsychiatric symptoms and institutionalization. High caregiver burden due to presence of neuropsychiatric symptoms may partially contribute to institutionalization among people living with dementia in Taiwan. However, proper management of neuropsychiatric symptoms and caregiver empowerment may ameliorate institutionalization risk.
