Late Stage Alcoholism

I empathize with your situation.  I recommend you be very up front with the facility you want your Dad to move into.  It is not uncommon for people who live in a Assisted Living Facility to have alcoholism.  That does not mean they are capable of handing some of the issues that may arise appropriately.  You are in a very difficult situation.

Continuing use of alcohol will continue to deteriorate the cognitive (thought) functions of the brain.  Is you Father willing to go to a long-term rehab facility?  I know it may seem like it is too late for him to stop drinking, but it is never too late.  Worst case scenario, he at least stops the progression of the disease and may return to some level of "normal" functioning.

If he is complacent about going somewhere, why not attempt to send him to treatment first?  Check out the options in your area.  If he was in the hospital after his fall with the hip, maybe you could ask the social work department at the hospital to help you.  If he is simply not willing, then consider other options.
