Only a few highlights this week as trajectories haven't changed, and I'm a bit fried after the excess deaths stuff this week:
- cases are down 21% and all age groups moving similarly; good
- PCR testing is down, but positivity rate is also down; good
- hospital admissions down 15%; excellent. The biggest % fall we've seen in a long time
- people in hospital down 6%; good. Hopefully this % will be even bigger next week as the lower admissions flow through
- 126 deaths; never good. But the lowest number in the seven weeks
- 43% of deaths were in aged care; lower than the 50%-ish we have been seeing
- nothing interesting on variants of concern; excellent
- flu is so over that I'm not going to mention it again!
The end. Questions?

Our latest estimates of excess deaths are out, covering all cause mortality to the end of May 2022, plus COVID-19 only mortality for Jun-Aug. #COVID19Aus#excessdeaths
TLDR: +8,500 excess deaths in 5 months to May (12%) actuaries.digital/2022/08/31/cov…
Note our excess deaths are measured relative to pre-pandemic expectations of mortality.
Includes allowance for continuation of mortality improvement/decline for each cause of death.
Allows for changes in the size and age composition of the population.
Another month of huge excess deaths in May. Only one week in 2022 to date has been within our 95% confidence interval
Nerd alert: I am massively happy to see age standardisation used in the methodology to estimate excess deaths.
This is a major flaw in the ABS commentary on its Provisional Mortality Statistics. Its "baseline" makes no allowance for population changes.
[I'm on an Actuaries Institute working group that has a specific focus on the mortality impacts of the pandemic. You can find out latest here.]
Our latest on excess deaths in Australia, covering all cause mortality to 30 April, plus excess from COVID-19 only to 31 July. #Covid19Aus
TLDR: 13% excess (+6,800 deaths) Jan-Apr 22.
8% excess (+3,500 deaths) from Covid only May-July.
Covid third leading cause of death in 2022.
Total excess mortality for the month of April 2022 estimated at 9% (+1,200 deaths).
More than half is due to doctor-certified COVID-19 deaths. Other unspecified causes and coroner-referred deaths (which include some COVID-19 deaths) also made a significant contribution.
With January at 20% excess mortality, February at 15% and March at 7%, this takes total excess mortality for the first four months of 2022 to 13% (+6,800 deaths).
In advance of our work on excess deaths coming out in the next day or so, and with quite a few new followers, I thought I'd do a thread on how we calculate our baseline predicted values for 2022, and how these compare to what the ABS uses. #COVID19Aus
What did we do? We used ABS standardised death rates (SDRs) for each cause of death as the basis of our projections. The SDRs allow for changes in both population size and age mix. We built in trends for mortality improvement. We then converted that back to numbers of deaths.
What do ABS do? They use the average number of deaths in 2017-19+21 without any adjustment for population changes or trend.
