My mom has been on hospice for over a year now. Her nurse has come every Wednesday at 4:00, with a few exceptions. The Social Worker and the Dr. Both call the day they want to come, and have even gone so far as to just "show up" because they are leaving town. I need an appointment set at least the day before so someone is here to let them in. Is this typical behavior for hospices or should I look for a new one?
