I understand about not trusting your mother to keep you informed about your dad in the hospital. When ever anyone close to me is in the hospital, I call the nurses' station directly. They don't seem to mind at all, and usually the nurse actually caring for your dad will take the call. As the daughter, there shouldn't be a confidentiality issue. You could even ask for help talking directly to your dad. The nurse might be able to go in the room and pick up the call and hand it over to your father. When my father was ill, I found staff more than willing to do this. One morning such a call led to me discovering that my father was much worse than I had been informed by my sister who was supposed to update me. So I immediately flew out and just got there before he was gone. Let them help you. They will. A good time to call can be in the middle of the night, when it's actually pretty calm at the hospital.
