My dad is an alcoholic, but I think he needs to be in a nursing home.

Pursue a medically supervised detox. At your fathers age -given the number of years he's been drinking and given his medical condition, detoxing any other way could kill him. Once he has detoxed you'll have a clearer picture as to whether assisted living or a nursing home will best address his needs. As for pissing him off - that should be the least of your worries. Sure, he won't be mad, as he'll probably be dead. Sorry.

I think probably he needs to go to detox and rehab before he can be placed. I would call your local area on aging. Tell them you think he needs more care than you can offer and about the alcohol problem. He might be willing to seek treatment if he is struggling a lot himself. Once he is in treatment for the addiction if you tell them he needs more support they will help you find it. You might find that if he stops drinking that he might be able to better care for himself. I also think you should go to alanon. In caring for him to well you might be helping him to continue to drink and be unable to care for himself. He can't quit drinking without medical treatment if he is an alcoholic. Most alcoholics have a vitamin B deficiency that can cause problems for them walking and caring for themselves. A medical detox will be needed to keep him from dying. They will treat him with B vitamins that should improve his health drastically. I would arrange for his treatment and tell him you can not continue to help him if he doesn't seek treatment and continues to drink. You feel stressed because this is a very complicated issue. Reach out to your area on aging they can help you

Well, its either a care faciilty (maybe assisted living rather than skilled nursing) or detox/rehab. You love the guy, and maybe he needs a little tough love, and maybe you could get more help and perspective via Al-Anon too. He really could die of his alcoholism with falls and liver disease, so worrying about pissing him off might not be the right thing to worry about. He needs medical care and help with his addiction, and possibly will be getting to the point where he will accept it. if not, you have an potion to call Adult Protective Services and explain that there is an elder (OMG 67is not that old though) unable to care for themselves and see what else can be done.
