Here’s the thing, and it’s unpalatable but is part of the answer to the “but the hospitals will be overrun” issue.
Like it or not (and I know it’s not the “NHS dream”), medical care is rationed. Always has been when it comes to the evaluation of the cost effectiveness of new treatments by NICE, now it is rationed on the basis of which condition you’ve got ... anything other than Covid, you need to wait, maybe til your tumour is inoperable, because there aren’t the resources to treat you. Where you live is probably a factor too.
So, we end up with this completely illogical and arbitrary rationing because we don’t want to make hard decisions about how to optimise resource allocation.
The most obvious starting point is a quality adjusted life years (QALY) type methodology and before I hear cries of “but how do we decide? what about dear Dame Judi versus a 29 year old crim?” I would say our health economists and ethicists would determine how it’s done in detail, just as for the funding of other treatments.
Some will be higher on the list, some lower. But it’s really the only alternative to a hierarchy based on who can pay the most or based on illogic like which condition we favour most at the moment.
