So I got a page yesterday evening. Since it was Sunday, I am not really obligated to answer, but I decided to risk it.
Pager: "Hi, this is the renal fellow. Are you familiar with a patient named [Patient I Never Heard Of]?"
Pager: "You don't know anything about [Patient I Never Heard Of]?"
Me: "No, sorry."
Pager: "Well, [Patient I Never Heard Of] never showed up to dialysis today and we've been looking for him. We've been calling everywhere. Do you know how we might find him?"
Me: "Sorry I can't be more helpful."
I guess he was just going through a list of everyone who worked at the hospital and paging them one by one?
