COVID-19 critical care bed modelling study: potential shortage in Canada

April 08, 2020

A national modelling paper predicting the number of available ICU beds across Canada during the COVID-19 pandemic suggests that self-isolation will likely not be enough to keep demand from exceeding supply. It is published in CMAJ (Canadian Medical Association Journal).

Researchers modelled several scenarios:"Our results show that higher rates of self-isolation are needed to mitigate the increased strain on the health care systems at the provincial level," writes Dr. Joanne Langley, Canadian Centre for Vaccinology, Dalhousie University and IWK Health Centre, Halifax, Nova Scotia, with coauthors. "Should resources allow for an increase in COVID-19 testing, a higher fraction of mildly symptomatic cases would be identified, which could lead to a higher percentage of the population practising self-isolation. If infection confers immunity, a testing strategy could also permit recovered people to return to normal activity."

The number of ICU beds in each province ranged from 0.63 to 1.85 per 10,000 people in the model.

"If the scenarios we describe are true, health care planning will move to crisis management in Canada, but at different times across the country," write the authors. "This may allow some redistribution of human or material resources across jurisdictions. While provinces and territories ramp up capacity for more ICU beds (human resources, ventilators, beds, personal protective equipment, infection prevention and control support), these estimates can inform the timing and quantity of the expected need."
