Back in Feb I posted a very similar story to you and received helpful advice similar to that quoted. It was as predicted. Deeming she had mental capacity, my Aunt returned home with a package of 4 care visits per day. However, instead of placing her bed downstairs as I thought agreed, OT left her with a written instruction by her chair to not go up the stairs on her own to bed or bathroom
Needless to say she was found at the bottom of the stairs by the carer within the week. I had already raised a formal complaint on her first day regarding unsafe discharge from hospital and the risk.
Needless to say, they changed their mind regarding mental capacity and she is now settled in a Care home in most importantly, a safe environment.
The real point of my reply is to express to you and everybody who experiences at first hand, inadequate or poor care/decision making, that they should officially raise these concerns with SS or the hospital PALS, and doggedly follow this through. If you do not, then the same errors and mistakes will continue to be perpetuated.
To cut a long story short, although the local authorities appeared reluctant at first, over a period of three months I entered in to a very extensive written dialogue with both SS and the hospital concerned, including 2 face to face meetings. They ultimately apologised for the errors and at the same time confirmed, based on the issues raised and findings, that changes in procedures and training would be made and in fact SS were using it as a case study in their training.
The Matron of Older Persons Services for the hospital thanked me and her final words to me were. "The only way we can improve is if more people raise these issues".
Oh my word ! This just terrifies me, I hope your Aunt is settled nicely now, that must have been an awful time for you. It's needless and so stressful and I wonder if the SW was having to go through something like this personally they would be so willing to allow their relative to go home
