As I understand it, a perfect storm:
* too many doctors were predicted by DoH in 2006 which led to a 6% cut in medical training places. We now have fewer doctors in the training system than we actually need, ditto nurses.
* at the same time there was a cut in the budgets to local councils affecting their care home provision or care in home services. Hence the stories of bedblocking in hospitals and some hospitals releasing elderly patients back home with neither care home nor care in the home provision. Then the hospitals pay again if early release means early return to hospital.
* any promises made now about ramping up the numbers of doctors and nurses, given the length of medical training, only comes in 7-10 years later for junior doctors, a lot longer for consultants.
* many doctors and consultants here have opted out of the system: they can earn more and have control of their own lives by going agency - but this means hospitals are paying more for them. The cap system recently introduced for their fees has left hospitals who comply losing out for essential coverage to those who don't comply.
* the Private Finance Initiative, introduced by John Major but embraced by Blair's government, meant hospitals were built or expanded on private money with horrendous paybacks. There is more than one major hospital where they have had to close wards to save money to meet the pay back terms - or even set up a charity to raise money to meet the pay back terms.
* More importantly, Jeremy Hunt has gone for the argument that we need 24/7 hospital care based on a contentious report that more people die in hospital at the weekend. It appears not to be true for the most part. His response was to lay it on the doctors when it seems medical coverage, availability of other services (blood tests, processing xrays) would be more key. He is not providing any more junior doctors or nurses, so if more cover the weekends they will be missing from other days.
