Hi Libby,
As exbus says, the Hospital, palliative care team, and hospice can all help with getting him home. A hospice team can very much deal with looking after someone at home, not just in a hospice. A hospital is not a nice place to be in any circumstances, do your best to get him home.
Now I don't know anything about his medical condition or your mindset at the moment, but from what I can see from your posts, you need to be in the mindset of helping him in the final stages of his life. If you are in that mindset you will be able to make progress towards an inevitable end as comfortably as possible. If you are in a mindset of cure or prolonging life, I think you are fighting a losing battle. Telling someone on an internet forum that they need hospice care for their father is not the easiest, most tactful thing to do, but the reality of posting on a cancer forum is that not all stories are going to end well.
Remember I don't know anything about his situation there may be things that I am missing, so only his medics can give sound advice, at best this forum can just give you opinions from lay people.
