I agree that the nursing/caring boundary needs to be clarified. But if someone has cancer and is being treated in hospital then they have a clear need for nursing and medical care, and has been only too clear to me in the last few years, the moment that need for nonstop nursing ends, out you go and if that means to a care home, you pay for your care.
My experience is that the majority of people in care homes do not need nursing, just care.
I know the big problem is dementia, but even then, most dementia patients seem to need care and supervision and not nursing. However, there are types of dementia and stages of dementia that do require nursing and I think these can and should be defined and nursing care provided at the expense of the NHS.
If hospitals want to pay patients to pay for accommodation and food then they are going to have to up their game considerably. When I said, further up this thread, I think, that if I was asked to pay for my food, I would opt for self-catering, I meant it. Overall individual dishes may taste OK, but overall I was appalled by the limited range of available when DH was in hospital, the way meals had to be ordered 24 hours in advance, the appalling lack of fruit and vegetables and the feeling that generally the food was nutritionally inadequate.
