Dad care. Any advice?

My dad had really bad fall 16 months ago, as I went to back door it was open slightly keys were on the outside door and there was blood everywhere to say I felt sick was an understatement first thought in my head was he had been attacked I opened the door to blood all over the kitchen the walls it was everywhere I went in to the living room to find dad sat on the sofa his face was a mess and he didn’t even know anything was wrong cut long story short we took him straight to hospital even though at first he refused to go his injuries were two black eyes one side of his face was was black and blue cut nose and both hands were broke he had no clue at all as to what had happened he didn’t even demonstrate he was in pain he ended up having 1st operation where they pinned his hands his two thumbs and fingers and bandage them up I stayed at his home with him I was awoken to dad sitting on my bed bandages off and he had pulled the pins out of his fingers which resulted in 2nd operation to replace pins re dressed for him to again pull the pins out as he said they were better, the hospital said there was no point doing operation again as he would just remove them again. He has carers since then 4 x a day and I go down every day his mobility has deteriorated
so after serious consideration I decided to have him assessed and we have now moved him down stairs he has had bed fall Matt commode and blocked the stairs off with gate we have 24/7 alarms through to emergency call Centre cameras in the kitchen living room and hallway so it’s set up like he lives in a bungalow and his carers 4 x a day I have tried to pre-empt as much as possible is there anything else you could suggest I need to do that I have not considered any suggestions would be gratefully received
