It is necessary to master knowledge specific to diseases and operations when caring for the surgical patient. However, knowledge of systems and conditions that affect the body as a whole, such as sepsis or coagulopathy, must also be learned. Our program encourages the Resident to care for the whole patient not just the surgical issue.


The Resident will be assigned to a service/specialty for one month. Duty hours will vary based on the preceptors’ schedule, surgery schedule and other factors. Residents will also be expected to attend conferences and committee meetings as mentioned in the Conferences section. One half day minimum of clinic is required each week during every rotation.

View an EXAMPLE of a block schedule.

Duty hours

Each resident in the program will document by program completion, participation, under appropriate supervision, a minimum of 850 major surgical procedures, as surgeon or first assistant. Of these 850 procedures, each resident should average 170 cases per year.

Resident work hours are in compliance with the guidelines established by ACGME and will be limited to 80 hours per week averaged over a four-week period, inclusive of in-house night call and any allowed moonlighting. Residents will be provided one in seven days free from all educational and clinical responsibilities- averaged over a four-week period and shall have no call responsibility during the time. When vacation time is taken, it will be averaged over a three-week period. Residents shall not work in excess of 24 consecutive hours with an additional 4 hours allowed (PGY+) for transitions of patient care must occur for patient safety and resident education.
