Husband Had Total Knee Surgery On 9/21 - Following That

Husband had total knee surgery on 9/21 - following that he developed a UTI and had a Foley placed - he has been unable to settle down at night and is still hospitalized. Various meds have been used - such as Halodol, Xanax, Lorazepam etc. He currently is in a Med-Psych unit. He is 80 years old and I am thinking that trying to bring him home might be the best for him where he is in familiar surroundings. Your thoughts?
