The whole free NHS Continuing Healthcare thing is a bit of a racket. Legally, they're obliged to offer it but yes, it very rarely happens. My mother had advanced Parkinson's, didn't speak really, no mobility and so on but was turned down for it.
On the other hand, one time she did get it and was fast-tracked. This was when a care home nearly killed her and she wasn't expected to live. So we got it for around eight months - brilliant! Just one thing. After they did this, we never ever got a care home to give her a drink again. Almost a bit like the Liverpool Care Pathway. I did get the impression that it's the golden handshake, sort of, hey here's free care and don't hang around.
Much pressure was applied to get her on a PEG feed, rather than getting her eating and drinking again, which I had to do myself.
Don't get me wrong though, a PEG is necessary when it's necessary and she did have it eventually. It's no picnic, but it bought her another eight months.
You are told your mother is 'refusing' to eat. They often phrase it that way when actually it can mean they can't be bothered or have given up. Have you seen it yourself? Are you allowed to visit?
BUPA care homes have an awful reputation.
