Abstract

Importance:
Nursing home residents have been disproportionately affected by coronavirus disease 2019 (COVID-19). Prevention recommendations emphasize frequent testing of health care personnel and residents, but additional strategies are needed.

Objective:
To develop a reproducible index of nursing home crowding and determine whether crowding was associated with COVID-19 cases and mortality in the first months of the COVID-19 epidemic.

Design, Setting, and Participants:
This population-based retrospective cohort study included more than 78?000 residents across more than 600 nursing homes in Ontario, Canada, and was conducted from March 29 to May 20, 2020.

Exposures:
The nursing home crowding index equaled the mean number of residents per bedroom and bathroom.

Main Outcomes and Measures:
The cumulative incidence of COVID-19 cases confirmed by a validated nucleic acid amplification assay and mortality per 100 residents; the introduction of COVID-19 into a home (=1 resident case) was a negative tracer.

Results:
Of 623 homes in Ontario, we obtained complete information on 618 homes (99%) housing 78?607 residents (women, 54?160 [68.9%]; age =85 years, 42?919 [54.6%]). A total of 5218 residents (6.6%) developed COVID-19 infection, and 1452 (1.8%) died of COVID-19 infection as of May 20, 2020. COVID-19 infection was distributed unevenly across nursing homes; 4496 infections (86%) occurred in 63 homes (10%). The crowding index ranged across homes from 1.3 (mainly single-occupancy rooms) to 4.0 (exclusively quadruple occupancy rooms); 308 homes (50%) had a high crowding index (=2). Incidence in high crowding index homes was 9.7% vs 4.5% in low crowding index homes (P? In this cohort of Canadian nursing homes, crowding was common and crowded homes were more likely to experience larger and deadlier COVID-19 outbreaks.
