What can I do?

Your profile says he lives in your home. Have you been managing his financial and medical affairs as well as his physical needs? If you are not his PoA and he has enough cognitive impairment to prevent him from assigning you, then you will need to get the county involved and they can acquire guardianship of him and take over providing for his needs.

You could consult with a Medicaid Planner for your state if you are privy to his financial assets. Most states' Medicaid will only cover LTC and they must also qualify financially. This is where the Planner comes in to help figure out what it would take for him to qualify.

Mstrbill mentioned the "ER dump": if your friend has to be admitted to the hospital, you make sure the discharge staff knows he is an "unsafe discharge" and that there's no one at his home (even though it's your home) to take care of him. They will apply a lot of pressure for you to come get him, and even tell the lie that they'll "help" you once he's back at home -- but don't believe it. You'll just be back at square one. Make sure no one goes to retrieve him and tell the hospital social worker that he has no one and no place to go. This is a "last choice" and a hard reality but at this point you still have options that don't involve you housing and caring for him. You need to take care of yourself!

You and your family member appear to be stuck in the donut hole of our inadequate support for elders with dementia in the country. There is no easy way to get out of it, but what you need to do is to, figuratively speaking, scream for help. What that means is getting the attention of the powers that be in the state, the police, APS, ER hospital nurses if necessary. You let it be know he is an elder at risk and YOU are not able to safely take care of him by yourself anymore. You are going to have to be proactive and vigilant. Eventually, you will get that help, he will be placed in a LTC facility paid by LTC Medicaid. This situation, that many finds themselves in, is why you see the "ER dump" being used. I'm not necessarily saying that is your first option, you may want to go to social services or your local agency on Aging first, but if you don't get help, you need to escalate it. Stay strong.
