Updated chart of probable hospital-acquired COVID-19
(diagnosed over 7 days after hospital admission)

English Acute Trusts with over 300 total cases since August 2020

Can we share learning points from the Trusts near the bottom?

Updated chart (data to 31st Jan 21)

Probable hospital acquired COVID-19 (diagnosed >7 days after admission).
English Acute Trusts with over 300 cases since August 2020

Chart shows percentage of cases that are probable HAI, and total case numbers.

As requested by @elinlowri - were busier trusts worse?

(divided total cases by acute overnight beds open September 2020)

Answer appears to be the opposite (though frankly it's a pretty poor correlation and looks strongly affected by a few outliers)

1/

The fact any correlation seems to be driven by the *very* busy trusts supports @MarkGregsonPara 's point that - if trusts were totally full of Covid-19 patients there wouldn't be any room for HAI as everyone already has it!

2/

Major flaw with this is that it's using total cases over the Aug-Jan period without differentiating hospitals that were hit in big spikes versus hospitals that had a more steady demand.

New data (to 7th Feb 21)

I've restricted this to the last 28 days for comparison with @ChrisMusson looking at this in Scotland, and to show trusts making changes.

Probable hospital-acquired COVID-19, English Acute Trusts with over 40 cases in the 28 day period.

Total COVID-19 cases admitted to English Acute Trusts for the 28 day period: 74,475

Total cases diagnosed day 8 or beyond (ie probably hospital-acquired): 8,974

HAI rate of 12% of cases

Period 10th Jan 2021 to 7th Feb 2021
