@hark123 This is a very difficult situation that you find yourself in and I can tell how much care about and love your nephew. If I'm doing the math correctly I figure your nephew is in his 30's now. Is that accurate?

In all likelihood your nephew is Medicaid-eligible. I am hoping that since he is currently in a hospital facility that the unit's social workers have helped him with Medicaid. In my experience many people who have serious mental health disorders who are homeless are also without medical insurance. I am in Michigan and so I know that your nephew would be able to have state Medicaid that would cover his treatment, meds, and ECT. Since Florida administers their own Medicaid I do not know what is covered and what is not covered.

@windyshores has offered some excellent advice. Your nephew has already indicated you as a contact for him. Since you have already talked with the hospital personnel he also must have signed a Release of Information for you to talk with his medical providers. This would include the social workers at the medical facility. The best I think you can do from such a distance is to talk with the social workers. While a group home could be a good plan for your nephew it often takes a lot of research and work to locate an agency that would provide such a group home. And then you can ask yourself - would my nephew want that? Can you talk with your nephew and ask what he wants to do? And would he actually stay there and take his meds as prescribed?

Will you please come back and post an update?
