It's really hard to make a blanket statement about this. I make visits if it would be helpful, to anyone, to do so. Usually SNF's don't want a visit - they've tidied up the patient and, unless family is there and need emotional support (often the SNF staff know them better than we do), there's not much reason to go. I DO notify the doctor and mortuary, and family if that's the staff's preference (again, they may have a relationship and prefer to call themselves). In my county we don't have to pronounce or involve the coroner.
My question to the caller now is "Would it be a comfort if I came out?" I don't want to shade the question to elicit a "no", but I also don't want to intrude; sometimes it feels that way, if the family is very matter of fact. Often it feels like the visit makes a huge difference, but sometimes it feels like they have to entertain me. I suspect this is a dicey issue for many hospice nurses.
