Beyond my pay grade, but not sure there is an answer to reduce ICU levels quickly. Going on the assumption that we have competent staff that are assessing these people correctly and that they require the length of stay that they do.
Its terrible to say, but most jurisdictions in the world have had something like covid death wards where people were not expected to recover. Those extremely severe poor prognosis cases were not in ICU for several months at a time. They were in another ward, and still getting care, but not expected to recover.
Ethically in Alberta, we have made the decision NOT to have that nature of transfer of any patients, they are remaining in ICU beds. Its an ethical quandary that most jurisdictions have not even had the good fortune, or luxury, to consider, they just ended up with the death ward decisions out of sheer necessity.
I mean of course you try to save every life if you can, fine and good.
But if you're saying that 4.2M people cannot resume more normal lives because of that, it becomes some other kind of thing.
I'm not saying one way or the other what to do with extremely ill patients, its just that you can't restrict a whole province on that basis of how we have specifically structured our ICU decisions.
