England has ten times the population of Scotland but nearly 30 times as many patients in intensive care. That’s a very significant difference and while causes will almost certainly be complex, they must be there.
Less dramatically, admittance to hospital with any level of Covid infection is twice as common in England:
There is at least as much poverty, underlying ill health, and old age in Scotland so that seems an unlikely explanation.
England has a higher percentage of BAME groups in the population than Scotland and the Asian sub-group does seem to be suffering more.
Contact -tracing in Scotland has been much more successful leading to more of the infected being tested early and, perhaps, admitted earlier before their conditions worsen.
Hospital-onset in Scotland is much less frequent in Scotland’s hospitals so the already sick are less likely to contract Covid-19 in hospital.
Staffing is significantly higher and staff absence much lower in Scottsih hospitals so better initial care may be also preventing conditions worsening.
