How long do you give specialists to call back and what is your plan of action with no response. This has come up at multiple sites I've been at. I'm talking about the bigger stuff... ie stroke, surgical trauma, stemi etc. Do you page another doc that is not necessarily on call? How long do you wait before you transfer a patient to another facility? A few examples I've seen are stab with free fluid in the belly- no call back 45 min, stroke- no call back multiple pages 2 hours.
