We had in house call for all 3 years of my IM residency, and when on call months we took call as frequently, or often more frequently, than the general surgery residents. However, on non call days our work hours would be less than the surgeons...we tend not to round with the attending physician at 6 a.m. or 6:30 a.m. ...7 or 8 is more the norm. Also, for IM you will have some months that are outpatient clinic and that have no call. I only had 1 as an intern, but as a 2nd and 3rd year you will have a lot more...4-6 months where you are on consultation months (where people call you to evaluate and see patients for things like GI, cardiology problems, etc.) and you do not stay overnight for call.
