A lot of nonsense happening

It seems like my father is being released from the hospital too early yet again, because he is causing so many problems there and fighting with the doctors and nurses. Last time it nearly killed him three weeks after he was released. Now he needs a bit of rehabilitation, but I doubt that he will do that. His mind isn't quite 100% right yet due to his kidney problems. He thinks that if he can walk or at least stand up, he can leave the hospital, and if he can leave the hospital he is healthy. It is impossible to explain the situation to somebody who doesn't listen and doesn't want to understand the situation. During the day, there is nobody who can really look after him, since everybody is working full time at stressful jobs.
