Home Health Quality among Hospitalized Older Adults with Alzheimer's Disease and Related Dementia: Association with Race/Ethnicity and Dual Eligibility before and during the COVID Pandemic

Objectives: During the COVID-19 pandemic, home health agencies (HHAs) discharges following acute hospitalizations increased. This study examined whether racial and ethnic minoritized and socioeconomically disadvantaged patients (ie, Medicare-Medicaid dual-eligible) were differentially discharged to below-average quality HHAs before and during the COVID-19 pandemic. We focused on post-acute patients with Alzheimer's disease and related dementias (ADRD), who are generally frail and have high care needs.

Design: Cohort study.

Setting and participants: We linked 2019 to 2021 Medicare data with Area Deprivation Index (ADI), Home Health Compare, and COVID-19 infection data. We included Medicare beneficiaries with ADRD who were hospitalized for non-COVID-19 conditions and discharged to HHAs between January 2019 and November 2021. The final analytical sample included 426,766 qualified hospitalization events.

Methods: The outcome variable was whether a patient received care from a below-average quality HHA, defined by an average Quality of Patient Care Star Rating lower than 3.0. Key independent variables included individual race, ethnicity, and Medicare-Medicaid dual status. Linear probability models with county fixed effects were estimated, sequentially adjusting for the individual- and community-level covariates. Sensitivity analysis using various definitions of below-average quality HHAs was conducted.

Results: Before the pandemic, Black and Hispanic individuals had significantly higher probabilities of discharge to below-average quality HHAs compared with white individuals (3.4 and 3.9 percentage points, respectively). Dual-eligible individuals were also 2.5 percentage points more likely to be discharged to below-average quality HHAs. During the pandemic, disparities in being discharged to below-average quality HHAs persisted among racial and ethnic minoritized patients and increased among duals. Findings were consistent with and without adjusting for individual covariates and across different definitions of below-average quality HHA.

Conclusions and implications: Persistent disparities were observed in being discharged to below-average quality HHAs by race, ethnicity, and dual status. Further research is needed to identify factors contributing to these ongoing inequalities.
