Throughout September 2022, NHS England has had twice the number, pro rata, of Covid cases in ICU than NHS Scotland. Wales with a significantly smaller population tends to have as many and, often more, that Scotland does.
This trend began around the beginning of August 2022. Before that Scotland had a similar rate to England.
Might this be the explanation:
From around October 2021, Scotland began to pull away from the other three nations and, notably has given third vaccinations to significantly more than NHS England has managed.
Other factors may have been the quicker vaccination of the elderly and staff in care homes and higher standards of infection control in Scotland’s hospitals.
By July 2021, 100% of Scotland’s care home residents had been fully vaccinated for some time. 97.6% of staff had the first vaccination and 94.4% had the second dose: https://www.travellingtabby.com/scotland-coronavirus-tracker/
In England, the situation was less reassuring, despite the PM’s claims of a ‘world-beating’ rollout. 98.5% of residents had both jags in English care homes for the elderly but only 78.4% of staff were fully vaccinated. This was a very disturbing figure: https://www.england.nhs.uk/statistics/statistical-work-areas/covid-19-vaccinations/
Comparative hospital infection levels are difficult to confirm as NHS England tends to avoid recording them but in December 2021, we could state:
In the Nursing Times on the 23rd July 2021 on the incidence and impact of Hospital Acquired Infections. The study was commissioned by the Scottish government and conducted by Glasgow Caledonian University.
“It found that 7,500 hospital patients, or one in every 100, develop HAIs each year.
This equates to 1.1% of patients in Scotland acquiring HAIs, which compared favourably with previous estimates in the UK (7.8%) and recent studies in wider Europe (3%), said the researchers.”http://www.nursingtimes.net/news/research-and-innovation/first-of-its-kind-study-shows-hospital-infections-costing-scottish-nhs-46m-a-year-23-07-2021/
