Ok, but again: The primary reason for this is the significant spread of SARS-CoV-2 which has overwhelmed hospitals. This in turn could have been prevented with lockdown(s). Right?

>overwhelmed hospitals

Something that has never been properly explained to me is how "overwhelmed" the hospitals were in relation to their normally "overwhelmed" state.

I wrote a script which extracted time series data from one of the hospital bed data APIs in my country around April last year and ran it for a couple of months. I wasn't able to make any useful conclusions from the data other than more patients were coming than going for a certain time periods and some wards had beds reassigned to other wards. It would have been a lot better if I had access to historical data to compare it to previous years.

The hospitals weren't (all) overwhelmed but were focused on managing the pandemic. Fewer appointments scheduled, procedures pushed back, no weekend services, that kind of thing. Perhaps an element of patients huddling at home and being less proactive in their own care.

(Btw I'm not in healthcare. If anything my point is a logical alternative to the idea that overwhelmed covid wards could be the only thing affecting other services. But it's my impression of how things seemed to be, at least in the UK).
