In my neck of the woods here, "hospital at home" is encouraged to discharge patients early after major surgery and free a bed. After my knee replacement I was discharged on a Saturday pm and on Sunday am firstly a physio came to assess me and then a nurse. I think that the physio came around 4 days until he was happy that I could cope. The nursing staff came daily for over a week.
The physio was very good, apart from showing me exercises, he did practical things like showing me the correct way to get in and out of a car on the passenger side.
I have had no experience of "end of life" care.
