AbstractBackgroundNursing homes have become the epicentre of the coronavirus disease 2019 (COVID-19) pandemic in Canada. Previous research demonstrates that for-profit nursing homes deliver inferior care across a variety of outcome and process measures, raising the question of whether for-profit homes have had worse COVID-19 outcomes than non-profit homes.MethodsWe conducted a retrospective cohort study of all nursing homes in Ontario, Canada from March 29-May 20, 2020 using a COVID-19 outbreak database maintained by the Ontario Ministry of Long-Term Care. We used hierarchical logistic and count-based methods to model the associations between nursing home profit status (for-profit, non-profit or municipal) and nursing home COVID-19 outbreaks, COVID-19 outbreak sizes, and COVID-19 resident deaths.ResultsThe analysis included all 623 Ontario nursing homes, of which 360 (57.7%) were for-profit, 162 (26.0%) were non-profit, and 101 (16.2%) were municipal homes. There were 190 (30.5%) COVID-19 nursing home outbreaks involving 5218 residents (mean of 27.5 ± 41.3 residents per home), resulting in 1452 deaths (mean of 7.6 ± 12.7 residents per home) with an overall case fatality rate of 27.8%. The odds of a COVID-19 outbreak was associated with the incidence of COVID-19 in the health region surrounding a nursing home (adjusted odds ratio [aOR], 1.94; 95% confidence interval [CI] 1.23-3.09) and number of beds (aOR, 1.40; 95% CI 1.20-1.63), but not profit status. For-profit status was associated with both the size of a nursing home outbreak (adjusted risk ratio [aRR], 1.96; 95% CI 1.26-3.05) and the number of resident deaths (aRR, 1.78; 95% CI 1.03-3.07), compared to non-profit homes. These associations were mediated by a higher prevalence of older nursing home design standards in for-profit homes.Interpretation: For-profit status is associated with the size of a COVID-19 nursing home outbreak and the number of resident deaths, but not the likelihood of outbreaks. Differences between for profit and non-profit homes are largely explained by older design standards, which should be a focus of infection control efforts and future policy.
