I got full NHS CC funding for my mother, who still lives in her own home. The circumstances are that she has very little congitive functioning - she doesn't know who anyone is (although she knows who she feels comfortable with), cannot communicate any of her needs (she talks incessantly, but what she says makes no sense), gets extremely upset/angry/agressive (very difficult to care for, which I suspect is why they have not pushed for her to go into a home), is doubly incontinent, and needs to be fed/given water most of the time. She has no mobility problems whatsoever, which puts her at risk in all sorts of ways as she cannot understand danger but can get to dangerous places very easily!
The
Decision Support Tool is the most important thing for you to look at, in as much detail as you possibly can. The people who assess your loved one's eligibility are required to use this as the basis of their decisions, but as other people have said, assessments are not always completely objective. I suggest you download the support tool and make a list of EVERYTHING you can possibly think of that might fall under any of the 'care domains'. Be sure to bring up every incident/habit/issue that you can think of at the meeting.
You will also need to be able to show how complex, severe and unpredictable your loved one's needs are.
Best of luck!
