Comparison of hospitalized patients with COVID-19 who did and did not live in residential care facilities in Montréal: a retrospective case series

Abstract

Q uebec was the epicentre of the COVID-19 health crisis in Canada between March and August 2020, accounting for more than half of Canada's cases and deaths. 1 As of Feb. 9, 2021, over 271 700 cases and 10 000 deaths attributed to COVID-19 occurred in Quebec, of which more than 50% of cases and 60% of deaths occurred in Montréal. 1 The first case of COVID-19 in Quebec was diagnosed on Feb. 27, 2020, in an international traveller. 2 Early transmission dynamics were driven by returning international travellers, many of whom were returning from school spring break. 2,3 By mid-April, however, numerous outbreaks occurred in public and private residential care facilities (RCFs). The residents of these institutions bore the greatest burden of the first wave of the pandemic, accounting for 70% of the deaths in Canada and Quebec, with a case fatality rate estimated to be 36% (range 20% to 42%). 2,4,5 Of the 59 845 patients with SARS-CoV-2 infection reported in Quebec between Mar. 1 and July 27, 2020, people living in RCFs represented a disproportionate burden of COVID-19, accounting for 23.4% of all patients, 43% of hospitalizations and 84.3% of deaths attributed to During the first wave of the pandemic, the incidence and mortality rates of COVID-19 peaked in Quebec in mid-May

In-hospital outcomes of SARS-CoV-2-infected health care workers in the COVID-19 pandemic first wave, Quebec, Canada

“…By mid-April 2020, COVID-19 swept through public and private RCFs in Quebec with numerous outbreaks [ 30 ]. By the end of the first wave (July 2020), residents of RCFs accounted for 22% of all cases, 28% of hospitalizations, and 79% of COVID-attributed mortality [ 30 , 31 ].…”

“…By mid-April 2020, COVID-19 swept through public and private RCFs in Quebec with numerous outbreaks [30]. By the end of the first wave (July 2020), residents of RCFs accounted for 22% of all cases, 28% of hospitalizations, and 79% of COVID-attributed mortality [30,31]. Widespread transmission was facilitated by chronic structural deficiencies in these institutions including crowding, communal spaces, low staff-to-resident ratios, reliance on a precariously employed workforce who worked in several facilities to earn a living wage (most with no sick pay) so they could not afford to take time off work, and lack of adequate PPE [32][33][34][35].…”
