Discharge Disposition for Home Health Care Patients with Alzheimer's Disease and Related Dementia: The Role of Living Arrangements and Rural Living

Purpose: To examine the relationship between living arrangements and discharge disposition, and how this relationship differs by the rural or urban characteristics of the patient's residence among home health care patients with Alzheimer's disease and related dementia (ADRD).

Methods: This retrospective study used the 2019 Outcome and Assessment Information Set and the Master Beneficiary Summary File. Our study was based on 531,269 Medicare fee-for-service patients with ADRD. We used linear probability regression models to examine the relationship between discharge disposition (to the community vs. an institution) and living arrangements, including an interaction term for rural-urban residence.

Findings: Patients in rural areas (19.8%) were more likely to live alone than those in urban areas (15.2%). Our main results show that patients living at home with others (coefficient: -0.02, p-value < 0.001) or alone (coefficient: -0.03, p-value < 0.001) were less likely to be discharged to the community compared to patients who lived in congregate settings. Also, for patients with ADRD who lived in rural areas, living at home with others (rural*home with others; coefficient: -0.02, p-value < 0.001) or living alone (rural*home alone; coefficient: -0.03, p-value<0.001) were associated with additional lower probabilities of being discharged to their communities.

Conclusions: A multidimensional approach considering living arrangements to support home health care patients with ADRD could be critical to achieving better health outcomes. Furthermore, implementing area-specific target interventions could be important for improving the care and health of patients with ADRD as well as reducing rural-urban disparities in discharge disposition.
