Some do, some don't. Depends on call expectations, overall case volume and room turnover, inpatient load and acuity,trauma, night float, your efficiency, and expectation about what you do when cases are done for the day. At my personal experience n=4 for a general surgery service :
Academic center 1: Intern chart/nurse pre-rounds 0500, chief led team round 0600, OR cases until 3-5 for the upper levels, sign out 5-6. Usually 1-2 big cases/ day ~3D/week, 1 day clinic, lots of seemingly meaningless busywork for the intern and midlevel.
Academic place 2: intern chart/nurse pre-round 0530, chief round 0600. 1-4 big whacks/day 2-4d/week. Sign out 6-7pm, some busy work but not as much with several NPs.
Community place 1: intern pre-round on every patient 0400-0600, have notes and orders ready and chief rounds 0600, then to pre-op where all hands are on deck by 0630 for 0700 starts for 1-8 cases/day 4.5d/week. Signout 6pm.
Community place 2: No set AM rounds, all patients expected to be seen, notes/orders done and pts pre-opped for 0730 start. 1-5 cases/day 4d/week. No sign out, home when cases done and patients tucked in.
