The Drs usually call us for a quickie report for pts coming down from the floor. They are always in house, so if they don't come down with the pt, then they will come down soon enough. Not all admissions NEED to be seen immediately by a physician. Besides, the physician already has written the transfer orders and has already assessed the pt upstairs. I'll call him with an update if it's been too long.
If I feel that the pt needs the Dr here I will simple call them and tell them that. Usually the Drs feel that once pts are in the unit that they are being taken care of, so then don't need to remain by their bedside.
Have I ever had a critical pt that needed a Dr and couldn't get one? No. But, that's the beauty of teaching hospitals and hospitalists.
