Well, only in as much as Brexit has restricted the availability of people prepared to do social care work for minimum wage from outside the UK. But that’s not the main cause of the current problems the NHS is facing.

The problems in the NHS are mostly structural & have been building ever since George Osborne chose austerity in the aftermath of the 2008 financial crash. NHS spending was ringfenced in real terms, but social care wasn’t as that was funded out of local authority expenditure. Social care is now difficult to access & in short supply nearly everywhere as a result. Care homes are closing under the pressure of the difficulties in employing staff & inflation in fuel costs running headlong into the squeeze on LA funding meaning that LAs have been forced to eliminate any/all discretionary expenditures.

For the NHS this has led to two issues that have got progressively worse over time: 1) the UK population is aging & old people need more healthcare, meaning that freezing NHS funding in real terms would inevitably result in a steady increase in healthcare need that couldn’t be met and 2) for those people the NHS did manage to treat the collapse in social care has made it impossible to discharge them from hospital safely in a timely manner.

Some estimates suggest that currently a third of NHS beds are occupied by people who could go home if a care plan was in place for them, but that care is either unavailable due to LA funding cuts (forced on them by a government which cut LA funding to the bone) and can take weeks to arrange as the staff doing the assessments are themselves in extremely short supply.

This bed shortage then has knock on effects that ripple through the rest of the system. Combine with the regular winter flu epidemic & Covid wave spiking demand & you end up with A&E full to the brim with patients dying on the floor whilst every single available ambulance sat queueing outside A&E with patients that cannot be left alone & with no-where for them to go.

All of this has been aggravated by Brexit, but we would still have ended up here without Brexit: the root cause is the intersection of the steady decline in healthcare & social care funding with the increase in demand caused by an aging population & two concurrent epidemics.

All this has been predicted for years, it was obvious from the data that the system was persistently overloaded: waiting times for NHS treatment were steadily increasing at every level, including A&E. The current collapse was entirely predictable, but our current government was either unwilling or incapable of doing anything about it.

Chunks of the left believe that this is a planned collapse - that at least part of the government intended to force the NHS into a state of collapse in order to drive through a US-style privatisation that would enable them to line their own pockets. We know that government ministers have met with representatives of US medical companies numerous times within the last few years, so this isn’t an entirely baseless conspiracy theory sadly.

I’m not personally against private companies being part of a national healthcare service - most of the EU provides healthcare on some kind of partially private basis, with many differences in the details. However the US system is the worst of all possible worlds - it’s extremely expensive whilst giving very poor coverage of the population. It’s impossible not to suspect that US healthcare companies are hoping for an opportunity to carve up the UK healthcare market along similar lines in order to line their own pockets - the cost of bribing government ministers with a few well placed post-government directorships would be a small price to pay.
