Sure, but that implies that surgeons control the operating room schedules. I am not sure that's true (it might be), but it's a contested resource in most hospitals.
Outside of emergency surgeries, I imagine anything scheduled that isn't of immediate risk surgeons have a reasonable amount of control over, given of course the magnitude and distribution of surgeries that need performed.
I can't imagine they don't look at their schedules regularly and talk to whomever does scheduling to make their lives more bearable.
When they're on ER rotation, surgeons of course really have no possible way to manage this. My question would be: what's the ratio of emergency to planned/scheduled operations?
ER cases might also not serve as a proper control - the types of injuries and accidents over the weekend will likely be different from those during the week days
The amount of influence a surgeon has in her schedule varies from place to place and specialty to specialty. It ranges from little control, to being able to look at a calendar and pick the date. Also, most surgeons do not operate on all days. In most large hospitals, surgeons have set OR days (ex. Monday, Tuesday, and half of Thursday) every week and it is incredibly difficult to change that.
