A system no longer able to keep pace with medical science. When it started it was affordable because the drugs available to doctors were quite limited and reasonably cheap to produce. The surgery that could be done was no where near as radical as it is now, when transplantation is considered major but routine in some centres, when back then older people got pneumonia it was still considered 'the old man's friend' and heroic measures were rarely used in the elderly, the disabled or those with developmental or learning issues. We gradually demanded more and more as a right, drugs became more and more expensive, sometimes one drug or therapeutic can cost tens of thousands of pounds per patient to give maybe only a few months extra life. Patients are treated successfully for cancers that would have been a certain death sentence just 10 years ago. But at huge cost especially with new immunotherapy regimes
And if patients don't get the treatments they look up on line and think they need they threaten litigation.
We have jobs created to provide data for the department of health, and specialist review bodies, more jobs created to monitor performance against targets that are impossible to achieve, and probably never were, increased litigation meant the expansion of legal departments,
Failure to maintain levels of social care provision in line with the demographics
Resulting in difficulty in discharging patients who can become institutionalised and need long term care when a short step down or home support may have been enough.
Failures in health education.... It hasn't worked The motivated few get fitter the rest get fatter, and many many more are developing serious illnesses as a result.
Poor quality housing and nutrition contributes leading to health implications especially in children.
The NHS has become an all consuming beast, to have the service provision people demand it would either require a massive tax hike, ( one consultant I knew felt if the budget was doubled then had a massive increase every year based on that amount it still wouldn't keep pace with either the ageing population, or new treatments coming onstream.). Or we need to accept it can't do the impossible and accept it will only provide according to a list of specific priorities. Maybe rationing or excluding lifestyle related problems, maybe moving to a more mixed health economy, maybe also fully funding the training of the staff we need, with free tuition and reasonable bursuries.
Comes down to pay tax or pay private. Either way you will have to pay.
