    During the COVID-19 pandemic, neighbourhoods with high material deprivation and high proportions of racialized Canadians were disproportionately affected by COVID-19. Many of these neighbourhoods were served by community hospitals. We sought to compare the burden of COVID-19 care in community and academic intensive care units (ICUs) in Ontario, Canada. We included all adult patients admitted to Ontario ICUs with COVID-19 between 1 March 2020 and 31 July 2021 in a retrospective cohort study. We compared patient volumes, demographics, interventions, and outcomes between community hospital corporations (CHCs) and academic hospital corporations (AHCs). During the first three waves of the pandemic, 9,651 adult ICU admissions for COVID-19 were reported across 72 hospital corporations in Ontario: 6,902 (71.5%) in CHCs and 2,749 (28.5%) in AHCs. Days of ICU care per baseline ICU bed were highest in large CHCs ([ 10 baseline ICU beds) relative to AHCs and small CHCs (median [interquartile range], 73.7 [53.8–110.6] vs 42.2 [32.7–71.8] vs 21.4 [7.2–40.3]; Kruskal–Wallis test, P \ 0.001). Among direct ICU admissions, CHC patients had greater severity of illness whereas among transfer ICU admissions, AHC patients were more severely ill. In a multivariable logistic regression model, mortality was similar among patients with index admission to a CHC or AHC; however, patients with index admission to an AHC were more likely to receive extracorporeal membrane oxygenation (adjusted odds ratio, 6.16; 95% confidence interval, 4.72 to 8.11). During the pandemic, Ontario’s large CHCs provided significantly more days of ICU COVID-19 care per baseline ICU bed compared with AHCs and small CHCs. Equipping large CHCs to handle ICU surges during future emerging disease outbreaks should be a priority for pandemic preparedness.

    Background: Most Canadians receive their care in community hospitals, yet most clinical research is conducted in academic hospitals. This study aims to compare patients with community acquired pneumonia (CAP) treated in academic and community hospitals with respect to their demographics, clinical characteristics, treatments and outcomes. Methods This nested observational cohort substudy of the Community Acquired Pneumonia: Toward InnoVAtive Treatment (CAPTIVATE) trial included 1,329 hospitalized adults with CAP recruited between March 1st, 2018 and September 31st, 2023 from 15 Canadian hospitals. Unadjusted and adjusted analyses for age, sex and co-morbidities using logistic, Cox and censored quantile regressions were conducted. Results Patients in community hospitals were older (mean [SD] 75.0 [15.7] years vs. 68.3 [16.2] years; p < 0.001), were more likely to be female (49.7% vs. 41.0%, p = 0.002), and had more comorbidities (75.9% vs. 64.8%, p < 0.001). More patients in community hospitals received corticosteroids (49.2% vs. 37.4%, p < 0.001). Community hospital patients had a higher likelihood of developing acute respiratory distress syndrome (OR 3.13, 95% CI: 1.87, 5.24, p = < 0.001), and acute cardiac injury (OR 2.53, 95% CI: 1.33, 4.83, p = 0.005). In unadjusted and adjusted analyses, 28-day mortality difference did not meet statistical significance (OR 1.43, 95% CI: 0.98, 20.7, p = 0.062 and OR 1.23, 95% CI: 0.81, 1.87, p = 0.332, respective). Conclusion Patients with CAP in Canadian community and academic hospitals differed with respect to their age, clinical characteristics, treatments and outcomes, emphasizing the importance of including more community hospitals in clinical research studies to ensure the generalizability of results.
