Important preprint: @LauraCRosella and colleagues.

Estimating excess mortality in #Ontario during #COVID19 first wave using cremation data

Some observations summarized in thread.

medrxiv.org/content/10.110…
Cremation numbers in #Ontario at peak of #COVID19 1st wave vs 2017-2019:

⬆️>30% deaths all ages
⬆️38% deaths in >75 age grp
⬆️89% deaths in longterm care homes
⬆️68% deaths at home

No significant change: hospitals deaths
Study monitors cremations as death indicator.

In ON ~70% of deaths cremated. No change in this rate from 2017-2019 to 2020.

So, increased cremations not due to increased cremation "popularity". Instead, likely related to excess mortality directly & indirectly due to #COVID19.

Oct 27 update: TAKE HOME

#Canada is performing similar to peers such as Germany in testing & controlling #COVID19 spread.

OUR FAILURE: When #Canadians get COVID-19 we’re more likely to die.

WHY? Longterm, congregate care, retirement homes.
