Everything depends on the particular Hospice organization. Some families are able to do more for their loved one than others. Some organizations provide more care than others do.
Families often have less to do. They no longer have to worry about things like changing feeding tubes, bathing their loved one, or other daily care functions that they may no longer be able to perform.
I in no way implied that families no longer had a great many responsibilities, simply because of Hospice. My point is that Hospice helps lighten the load. I think that is obvious.
