Persistence of Racial Inequities in Receipt of Influenza Vaccination among Nursing Home Residents in the United States

BACKGROUND: We sought to determine if the racial differences in influenza vaccination among nursing home (NH) residents during the 2008-09 influenza season persisted in 2018-19.

METHODS: We conducted a cross-sectional study of NHs certified by the U.S. Centers for Medicare & Medicaid Services during the 2018-19 influenza season in U.S. states with ≥ 1% black NH residents and a white-black gap in influenza vaccination of NH residents (N=2,233,392) of at least one percentage point (N=40 states). NH Residents during October 1, 2018 through March 31, 2019 aged ≥ 18 years and self-identified as black or white race were included. Residents' influenza vaccination status (vaccinated, refused, and not offered) was assessed. Multilevel modeling was used to estimate facility-level vaccination status and inequities by state.

RESULTS: The white-black gap in influenza vaccination was 9.9 percentage points. In adjusted analyses, racial inequities in vaccination were more prominent at the facility- than at the state-level. Black residents disproportionately lived in NHs with majority blacks, which generally had the lowest vaccination. Inequities were most concentrated in the Midwestern region, also the most segregated. Not being offered the vaccine was negligible by difference in absolute percentage points among whites (2.6%) and blacks (4.8%) whereas refusals were higher among black (28.7%) than white residents (21.0%).

CONCLUSIONS: The increase in the white-black vaccination gap among NH residents is occurring at the facility-level, in more states, especially those with the most segregation. Standing orders for vaccinations, previously reported to narrow the racial gap in vaccination among NH residents, should be considered.
