I wish you every success in getting funding, OP, but don't hold out too much hope. From what you said, my Mum was very similar to yours, but was refused funding. I was in the process of preparing to appeal when she had a massive stroke and died three weeks later. I carried on with the appeal as a matter of principle because she would have been so horrified that she was paying £1500 per week for her care home. Her dementia fell off a cliff edge two months before she went into the home because of the way that Bexley social services treated her which ended up with her being readmitted to hospital with full blown delirium, to the point where it took four members of staff to restrain a frail 95 year old woman. I took the CHC appeal through the local stage and to NHS England, and still lost.
When things got really serious for my mum, I heard about companies that will prepare your case and represent you throughout the process, and using one of these was the biggest mistake I made. I was told by one of their advisers that my mum had a very a strong case and I employed Compass to handle the application. They were absolutely useless and all I got for my £5000 was a report, albeit very detailed, which was not available at the time of the decision support tool meeting but was only sent on the day of the CHC Panel meeting. The person who I spent an additional £1000 to represent me at the virtual meeting spoke TWICE. Please don't anyone let themselves be conned into using one of these companies.
My mother in law also got turned down for chc funding earlier this year. She had very severe dementia and a range of physical problems. She spent seven weeks in Lewisham hospital at the end of last year before finally being discharged into a nursing home. For six of these weeks we were trying to make Bromley social services thst she needed nursing care rather than an ordinary care home. She deteriorated dramatically during this time and we realised that the hospital staff weren't feeding her - they were typically leaving a wrapped sandwich on her table and a carton of juice out of reach. We had made it clear that she was very reluctant to eat and would only eat with a huge amount of encouragement, but they basically left her to starve. We were taking in food to feed her every day, but didn't realise the extent of the neglect until she had been in there for three or four weeks. When she was discharged to the nursing home, she was unable to even reposition herself in bed, had no idea where she was, and could barely speak. She had been fully incontinent for many months by then and it was obvious that she had a very short time left to live. Her funding was rejected as well.
I think it should be made clearer just how hard it is to get CHC funding rather than waste people's time and emotions letting them think there is a chance.
