Comparison of resident COVID-19 mortality between unionized and nonunionized private nursing homes.

Using bargaining agreement data from the Federal Mediation Conciliation Services, we found that the median national resident COVID-19 mortality percentage (as of April 24, 2022) of unionized nursing homes and that of nonunionized ones were not statically different (10.2% vs. 10.7%; P = 0.32). The median nursing home resident COVID-19 mortality percentage varied from 0% in Hawaii to above 16% in Rhode Island (16.6%). Unionized nursing homes had a statistically significant lower median mortality percentage than nonunionized nursing homes (P < 0.1) in Missouri, and had a higher median mortality percentage than nonunionized nursing homes (P < 0.05) in Alabama and Tennessee. Higher average resident age, lower percentage of Medicare residents, small size, for-profit ownership, and chain organization affiliation were associated with higher resident COVID-19 mortality percentage. Overall, no evidence was found that nursing home resident COVID-19 mortality percentage differed between unionized nursing homes and nonunionized nursing homes in the U.S.
