Mom doesn't want to eat, the hospital is feeding her through IV. Is this just another way to prolong her life?

I don't see why not.

Do keep in mind that Mom may continue to be combative at home. She may refuse to eat.

I see from your profile that Mom has dementia as well as a broken hip. Is she in the final stages of dementia? If so, consider having a hospice evaluation.

Is Mom on Medicaid? If so have her case manager schedule a needs assessment as soon as you bring her home, to determine what services and products Medicaid will cover at home.

This is a very painful situation for you, I'm sure. If bringing her home is what you want to do, I sincerely hope it works out for you both.

I went through the same thing with my mom. I think it's possible she's telling you that she's had enough. Mom had a broken neck but was then moved to a nursing home. She gave up after that and wouldn't eat a thing. My stupid brother had them put in a feeding tube. I was told it could be removed after 6 weeks if we wanted. Don't believe that because it's not always true. Very hard to get one removed. I feel for you but I also know that my mom was telling us it was the end and to let her go. Bring her home. I couldn't because my brother had medical POA and wouldn't allow it, but she begged me to often. Please take care of yourself as well. Hugs
