The authors of the review define the concept of excess mortality as
the number of deaths from all causes that exceeds the expected number and
makes it possible to assess the direct and indirect impacts of the pandemic and to compare countries with each other. She would be the measure
the most neutral to draw an initial assessment of the impact of COVID-19 in Quebec.
Thus, from February 23, 2020 to January 2, 2021, no less than 5,400 deaths were considered to be surplus and attributable to the pandemic, or 9% more than the number expected in normal times.
In the case of this report, the expected mortality was calculated based on the figures for the previous eight years.
The expected number of deaths takes into account age, annual trends and population growth, we explain.
This portrait of excess mortality reflects the situation on January 2, 2021 and suggests that, unlike many places in the world, there has been no underestimation of the number of deaths due to COVID-19 declared in Quebec., also mentions the study.

Hard Spring 2020
Spring 2020 was particularly gloomy in Quebec. For the period of March 22 to June 17 alone, excess mortality reached a rate of 25%, with 4,500 of the 5,400 deaths compiled.
The rate reaches 30% among those 80 and over during this difficult period.
The fact that people residing in CHSLDs were disproportionately affected during the first wave explains this result., point out the authors.
The situation subsequently resolved in the second wave, when the excess mortality rate fell to 6%, or 1,500 deaths, from September 13, 2020 to January 2, 2021. The disparities between age groups have also disappeared. during this period.
The possibility that COVID-19 substituted the role of influenza and other respiratory viruses in deaths among more vulnerable people could explain this result, we specify in the report.
The INSPQ plans to produce new analyzes taking into account vaccination and the emergence of new variants.
