Why won’t other communities take him? / how did they find out that he’s combative? Was he 302-ed to a psych unit before? When communities find out that someone got sent to psych, they often don’t want to take him. I would talk to a physician (a geriatric doctor) to see if there is medication that can help take the edge off of his anger. What’s going to happen, if he lashes out because people aren’t approaching him correctly/he’s not on the right medication, he will keep getting sent out to psych and then sent back.
I would recommend looking at communities that are memory care-only. Is there a community somewhere nearby you that specializes in dementia? It would need to be a locked unit. Sometimes people who are “combative” get sent to SNF dementia units, but that isn’t always the best plan.
