The Role of Neighborhood Socioeconomic Status in Institutionalization of Home Health Care Patients With and Without Alzheimer's Disease and Related Dementias

Abstract

ObjectivesTo assess whether neighborhood socioeconomic status (SES) moderates the association between Alzheimer's disease and related dementias (ADRD) and successful discharge to the community. In addition, to explore whether the role of neighborhood SES on successful discharge for patients with ADRD varies by the severity of ADRD. DesignThis is a retrospective cohort study. Setting and ParticipantsMedicare Fee-for-service beneficiaries, aged 65 or older, who received home health care in 2019. MethodsWe used linear probability regression models with successful discharge to the community as the main outcome, and neighborhood SES and ADRD as independent variables. Also, we modified the Functional Assessment Staging Tool (FAST) to measure ADRD severity. ResultsOur study results show ADRD and residing in neighborhoods with lower socioeconomic conditions were independently associated with lower probabilities of successful discharge to the community. We also found that the differences in probabilities of remaining at home between patients with and without ADRD were larger among those in neighborhoods with lower SES (ADRD∗less disadvantaged neighborhood, coeff: −0.01, P < .001; ADRD∗more disadvantaged neighborhood, coeff: −0.02, P < .001; ADRD∗most disadvantaged neighborhood, coeff: 0.032, P < .001). Among patients with ADRD, patients with the most advanced ADRD were less likely to remain in their homes and community when living in neighborhoods with lower SES. Conclusions and ImplicationsOur study results show that when patients with ADRD receiving home health care live in neighborhoods with lower SES, they face further challenges to remaining in their homes and community. Public health officials and community planners should consider using area-level interventions to improve care and health outcomes for patients with ADRD. Also, further research aimed at identifying the specific factors and resources influencing lower care quality and poorer health outcomes in socioeconomically disadvantaged neighborhoods, particularly for patients with ADRD, can provide valuable insights for the development and implementation of targeted interventions.
