Hope someone else chips in with this.
We were persuaded to put mum in a nursing home after my dad pushed the red button and got the ambulance to come round to help her up the floor once too often.
We were not quite informed by the hospital that the minimum for these places, assuming your Dad has saved a fair cop in his many decades, is - brace yourself - £800 a week. Dad was wheedling to get Mum in a home, he is mean and that info would have changed his mind. The only exception is called Primary Care, I think, but that is when someone is on their death bed, has terminal cancer or something, is in dire pain, so gets paid for by the State even if the family can afford it
We sleepwalked into it, we are that kind of family. So well worth avoiding if you can, and you will also avoid all the stress and hassle of getting involved with care homes where frankly you have little or no leverage, read some of the posts on other threads if you want an idea of what to expect. There are no review websites for care homes like with Amazon or TripAdvisor. You find out what they're really like after you've signed up. But it does depend if you have anyone else to help out, like a spouse, during the day, when it comes to getting carers in.
BTW: Care Home = Resident can feed themselves.
Nursing Home = Resident can't feed themselves, needs carer to help with it. This costs more, and with fewer nursing homes around, limits your options. Many nursing homes have screamers and dementia patients, but some have the flavour of a care home where some of the residents are compos mentis, not all of them need 'nursing' treatment and create a more genteel air.
'Nursing' home does not mean resident is on their sick bed, about to have a heart attack necessarily, it just means at a minmum they need feeding. My Mum doesn't really need 'nursing' just feeding, but a nursing home it has to be, it seems.
