My father went into hospital for leg surgery. Surgery went well, he was confused in hospital (as always). then went to rehab for his leg. Got aggressive at rehab and they shipped him over to a specialty dementia hospital. I am his POA. They say he will have to stay there for 17-23 days but then he may not get out. I plan on caring for my father at home once he is out. I know he is not happy there and wants to be home with his dogs and his routine, etc. He was functioning at home well with care. How can I go about getting him released so he can be home for Christmas??
