I came from a facility that would page the doc right before we went to see the patient in holding to see where they were, and if they need to see the patient, etc. Then I went to another OR where every doctor sees their patient before the circulator takes the patient anywhere. However, we do have a few docs who like to A: see the patient in the OR and ask them if there are questions (this usually happens when they're on the table, being preoxygenated with a mask over their face...I'd freak if I were the patient!).
And then there's scenario B: One of our docs insists that his cut time be exact, so he insists that all his first patients of the day be in the room, asleep, prepped and draped before he makes his grand appearance. Granted, he may have seen them the day before, or early in the AM, but either way, you'll never see me in his office! If he doesn't see the pt that day, how does he know who's under the drape? And like everyone else has said, what if he gets into an accident right outside the hospital and the patient is asleep and ready just to be awakened to a cancelled case? And yes, he is usually late, so his exact cut time isn't exact, and he complains about turnover time...TO YOUR FACE AS YOU ARE TRYING TO CLEAN AS FAST AS YOU CAN. Then he goes wherever he goes and by the time the next patient is on the table and ready, you have to page him...he shows up 10 minutes later.
