Latest surgery May 2018, brain cancer. It depends on (1) the hospital and (2) how they write you up for Home Care. My hospital (I'll never go there again) wouldn't let me do a blessed thing except under supervision, and even then all i got to do was watch the nurse or the physical therapist. The excuse was always "Liability".
To get a home nurse, the hospital had to write it up just right. I was wondering why they called me "Bedridden" and "Homebound" . Under Medicare rules, i couldn't get home help (nurse or otherwise). Went with the pull-ups as soon as i left the hospital, they wanted me to use those open-with-temporary-tape ones.
