From Public Health Scotland today:
The total number of probable and definite hospital onset COVID-19 cases reported to ARHAI Scotland this week (week ending 20 November 2022) was 104.
Of these 25 were reported as probable hospital onset (first positive specimen of COVID-19 episode on days 8 to 14 of admission to NHS board). In the previous week (week ending 13 November 2022) there were 64.
79 were reported as definite hospital onset (first positive specimen of COVID-19 episode on day 15 of admission to NHS board or later). In the previous week (week ending 13 November 2022) there were 119.

Lowest in the UK? Based on the limited resources. See this from November 2022:
A very powerful indicator of the effectiveness of a hospital, of a health board and, of course, of a health secretary, is the extent to which patients are protected from becoming more ill after admission due to a hospital-acquired infection (HAI).

HAI Covid data is published weekly by Public Health Scotland but has been tricky to find for other parts of the UK
In October 2022, however, the above graph popped up in Twitter, with this commentary:
Hospital-Acquired Covid in England – 20th October update In the last 28 days, 11,234 of 30,439 people in hospital with Covid probably or definitely caught it there (36.9%) Still extremely high; seems to be stabilising at around a third of Covid patients catching it there!https://twitter.com/LawtonTri/status/1583052116356390913
In Scotland, we can see that the equivalent figure was 817 probable and definite cases.
With 10 times the population, NHS England might have had, all things being equal, around 8 170 cases but had 11 234, 37% more.
With 3 548 Covid cases in Scottish hospitals in the same period, 817 HAIs is only 23% compared to 37% in NHS England.
Note, the two 37% figures is a coincidence.
