Elder-caregivers

He still lives home with my mom,they're 90. He has end stage heart failure & dementia. It's taken 6 months & several falls along with my mom having a psychotic episode from lack of sleep to convince them to allow help at home. I convinced them after the last fall, my mom couldn't get him up & hurt herself trying, she had to call 911 & of course they wanted to take him to a hospital which agitated him because he didn't want to go, so I told him if he lets these people help him he won't have to go to a hospital again. Otherwise if he falls mom would have to call 911 again. Also I said mom could fall & what would he do?
All this got arranged via his doctor who has been wonderful, she has a caseworker in her office who arranged everything. Medicare is covering it.
My dad is vaguely upset about hospice but I told him it just means medicare will pay, he's being being able to make decisions, while he's still can walk a few steps he is at the failure to thrive decline where he's barely eating. So he's got a hospital bed, wheelchair, commode & a home health aide. He has his emergency kit for if he's uncomfortable.
This is all new to them, just the past 2 weeks. My brother is staying with them temporarily. We've had to lie to both of them. My dad is failing, we told mom she can always take him out of hospice. He's not going to get better but they aren't ready to hear that.
