Hospital admissions with Covid in England increased by 33% in the last week of April, having been low and stable for a month. Most regions saw significant in-week increases. The fasted increases were in NE+Yorks (+52%), Midlands (+39%) and South East (+38%).

There’s been a bit of an unpleasant and inaccurate narrative over recent days that the majority of COVID-19 deaths were people who were “at death’s door” in any case. That they died “with” rather than “of” the disease. I want to address that. 1/8

This rhetoric is divisive and unhelpful, particularly the headline. It’s correct to say we are experiencing significant excess deaths. It’s also correct that much of the excess didn’t arise directly from COVID. But I disagree with calling these deaths “lockdown effects”. 🧵

So what the chart above is really showing is that within the 10-59 age band the average unvaccinated person is much younger than the average vaccinated person, and therefore has a much lower death rate. Any benefit from vaccines is swamped by the increase in death rate with age.

Are A&E pressures really leading to hundreds of additional deaths each week? @ActuaryByDay and colleagues @LCP_Actuaries crunch the numbers and conclude that a significant number of patients could be dying because of long delays accessing emergency care.

Some ‘interesting’ replies. It doesn’t matter whether I think lockdowns are ever necessary. Point is, lockdowns are a tool Governments will use when hospital capacity is threatened. If we want to avoid them we should think twice before opposing other measures (eg masks, wfh, vax)

@AlistairHaimes Even 18 months in it still astounds me that most so-called “lockdown skeptics” vocally oppose any and all measures which might prevent lockdowns from becoming necessary.

This is a perfectly reasonable question. #VaccinesWork and the UK vaccination effort has been incredible, so why do so many people, including me, feel that unlocking on June 21 is just too much of a risk right now? 🧵 (TLDR: Delta/India variant, cases 📈)

Can anyone answer this basic question: If the #CovidVaccine works against the Delta/Indian Variant, as it seems to, then people may get Covid but they won't be seriously ill or die. Which means a rise in cases won't overwhelm the NHS. So why not unlock on 21/6 as planned?

2. The claim that if no-one was vaccinated there’d have been under 340,000 deaths in England in a 12 month period is incredible! Anyone with relevant expertise should know straight away that this must be false. There have been over 450,00 deaths a year for the last 25 years!

Interesting and quite different from the impression you might get from (social) media. Around twice as many say handling of covid was “not strict enough” versus “too strict”.

I've been poring over today's NHS data releases and the picture for emergency care isn't pretty. Last year I estimated 400 additional deaths a week arising from A&E delays, Sep-Nov. This year looks just as bad, despite less Covid and flu - so far!

Analysis by @jburnmurdoch shows a fairly strong association between A&E waits and excess deaths this summer and last.

I am deeply skeptical about the headline conclusions from this new Oxford uni study. A more considered response will follow but brief thoughts now on why I don’t believe the conclusion that over half the UK has had the virus. 1/9

@chrischirp Agree entirely. There is no doubt whatsoever that clinicians on the ground were making tough triaging decisions about where to direct their limited resources.

A note on triage. Here‘s the Decision Support Tool which aids clinicians deciding who to admit to ICU. I don’t know how long this has been in effect - I’ve been sent it a few times in last 24hrs but not before that. If total score is 9 or more the guidance is not to admit. /14

Great show of support for vaccination from the intensive care community yesterday! Follows TV coverage of an anaesthetist with unusual views. There are individuals with fringe views in every profession. Problems arise when they get disproportionate visibility on (social) media.

I’ve gained around 800 followers today - very unusual. Thank you to those who RTd or recommended me - it is much appreciated. It’s usually a bad sign when people are interested in what a mortality expert has to say - sadly this time is no exception. Still, welcome new followers!

Across all ages, deaths in a private home were 22% higher than expected compared with 10% in hospitals, no excess deaths in care homes, and 12% fewer deaths than expected in hospices. Deaths from cardiovascular causes in private homes were 27% higher than expected.

A classical example of Simpson’s Paradox is currently doing the rounds on social media. I’m always loathe to share misinformation, but at this point it is probably fair to say that this chart is already very much “out there”, so here it is.

2. Current delays for urgent NHS care are extraordinarily long. See chart below for those waiting >12 hours in A&E for example. Ambulance waiting times and other statistics are equally concerning. Staffing levels, ability to discharge patients and demand are all relevant here.

In fact, we can go back further… much further. You would have to go back to the 1840s, when the population of England was much smaller, so see so few deaths in one year! If it wasn’t so serious these claims endorsed by John Campbell would be laughable.

@TonyHinton2016 @abirballan @CMO_England @sajidjavid @ONS Using such a broad age group (10-59) is highly misleading. Most of the unvaccinated people are young. Most of the vaccinated people are older. Since death rates increase sharply with age the protective effect of the vaccines can’t be seen here. This chart is deception!

When John Campbell describes the stitching together of the data as “a really clever way to look at this” he is completely wrong. This statistical bodge job gives estimated death rates for unvaccinated people which are about half what they should be.
