Racial disparity in end-of-life hospitalizations among nursing home residents with dementia.

ABSTRACT:

Objective

Explore within and across nursing home (NH) racial disparities in end-of-life (EOL) hospitalizations for residents with Alzheimer's disease or related dementia (ADRD), and examine whether severe cognitive impairment influences these relationships.

Design

Observational study merging, at the individual level, C2014-2017 national-level Minimum Data Set (MDS), Medicare Beneficiary Summary Files (MBSF), and Medicare Provider Analysis and Review (MedPAR). Nursing Home Compare (NHC) was also used.

Setting

Long-stay residents who died in a NH or a hospital within 8 days of discharge.

Participants

Analytical sample included 665,033 decedent residents with ADRD in 14,595 facilities.

Main outcomes and measures

The outcome was hospitalization within 30 days of death. Key independent variables were race, severe cognitive impairment, and NH-level proportion of black residents. Other covariates included socio-demographics, dual eligibility, hospice enrollment, and chronic conditions. Facility-level characteristics were also included (e.g. profit status, staffing hours, etc.). We fit linear probability models with robust standard errors, fixed and random effects.

Results

Compared to whites, black decedents had a significantly (p < 0.01) higher risk of EOL hospitalizations (7.88%). Among those with severe cognitive impairment, whites showed a lower risk of hospitalizations (6.04%). But EOL hospitalization risk among blacks with severe cognitive impairment was still significantly elevated (β = 0.0494; p < 0.01). A comparison of the base model with the fixed and random-effects models showed statistically significant hospitalization risk by decedent's race both within and across facilities.

Conclusions and relevance

We found disparities between black and white residents with ADRD both within and across facilities. The within-facility disparities may be due to residents' preferences and/or NH practices that contribute to differential treatment. The across facility differences point to the overall quality of care disparities in homes with a higher prevalence of black residents. Persistence of such systemic disparities among the most vulnerable individuals is extremely troubling.
