Resident racial and ethnic composition, neighborhood‐level socioeconomic status, and COVID‐19 infections in California SNFs.

Background: In California, >29,000 residents in skilled nursing facility (SNFs) were diagnosed with novel coronavirus disease 2019 (COVID‐19) between March 2020 and November 2020. Prior research suggests that SNFs serving racially and ethnically minoritized residents often have fewer resources and lower quality of care. We performed a cross‐sectional analysis of COVID‐19 incidence among residents in California SNFs, assessing the association of SNF‐level racial and ethnic compositions and facility‐ and neighborhood‐level (census tract‐ and county‐level) indicators of socioeconomic status (SES). Methods: SNFs were grouped based on racial and ethnic composition using data from the Centers for Medicare and Medicaid Services; categories included SNFs with ≥88% White residents, SNFs with ≥32% Black or Latinx residents, SNFs with ≥32% Asian residents, or SNFs not serving a high proportion of any racial and ethnic composition (mixed). SNF resident‐level COVID‐19 infection data were obtained from the National Healthcare Safety Network from May 25, 2020 to August 16, 2020. Multilevel mixed‐effects negative binomial regressions were used to estimate incidence rate ratios (IRR) for confirmed COVID‐19 infections among residents. Results: Among 971 SNFs included in our sample, 119 (12.3%) had ≥88% White residents; 215 (22.1%) had ≥32% Black or Latinx residents; 78 (8.0%) had ≥32% Asian residents; and 559 (57.6%) were racially and ethnically mixed. After adjusting for confounders, SNFs with ≥32% Black or Latinx residents (IRR = 2.40 [95% CI = 1.56, 3.68]) and SNFs with mixed racial and ethnic composition (IRR = 2.12 [95% CI = 1.49, 3.03]) both had higher COVID‐19 incidence rates than SNFs with ≥88% White residents. COVID‐19 incidence rates were also found to be higher in SNFs with low SES neighborhoods compared to those in high SES neighborhoods. Conclusion: Public health personnel should consider SNF‐ and neighborhood‐level factors when identifying facilities to prioritize for COVID‐19 outbreak prevention and control. [ABSTRACT FROM AUTHOR]
