Thank you all for your input. The person we are talking about is my darling mum and she came to live with me about 20 years ago. Throughout my adult life, whenever she has had to go to hospital or needed any looking after, it has been me who took care of her and she has always been totally open with me about her health. She has mild dementia, but on her clear days I have several times asked her if she has ever had any kidney problems she didn't tell me about and she says she has never had any. I have always been the one the doctors speak to about her and nobody has ever mentioned kidney failure. But somehow at some stage someone put stage 3 kidney disease down on her files. However, I am as sure as I can be that this was done by mistake. She has never had any of the symptoms mentioned nor any medication for this disease. So I have now for the third time asked that this be taken off her care plan. Let's hope this time they do it. But again, many thanks for your help peeps. Much appreciated.
