How can I force dad into assisted living or at the very least taking on an in home caregiver for a few hours a day?

Dad is 84 and has spent 21 of the last 2.5 months in the hospital... Small stroke and then small heart attack. He's two days out of the hospital and, of course, still weak, not eating and adamant that he will be fine when my brother has to leave in 4 days to head back to his Texas home. I am in Arkansas and spent the first 6 weeks with him.

My older brother and sister in law live across the street, but she is in poor health herself and can't help and my brother works and then has his hands full taking care of her. He does check on dad, but that's not the same as living there.

We all feel dads best choice would to be move in with one of us, but he refuses. He also refuses to even consider assisted living or for a stranger to come live in his house. Even his doctors say he should not be living alone right now...

Can we force him somehow? He has a trust and I am POA and Trustee for all matters. Problem is, it's a revokable trust and I'm afraid if I try to force him, he'll simply change the trust and take away my powers to do so.

It's so frustrating, since we only wants what's best for Dad, and we're all afraid he's going to die trying to live alone at this point.

Any suggestions would be helpful. Thanks!
