Development of a Night Float Call Model for Obstetrics and Gynaecology Residency: The Process and Residents' Perceptions.

The 2013 pan-Canadian consensus Report on Resident Duty Hours identified that traditional 24-hour duty periods pose risks to the well-being of residents and should be avoided. In anticipation of duty-hour restrictions, the Obstetrics and Gynaecology Residency Program at the University of Toronto developed and implemented a night float (NF) call model over a three-year span. Quarterly resident surveys have consistently shown that the NF system is preferred to traditional 24-hour call and has resulted in reduced fatigue and improved continuity of patient care. Through many iterations, the NF model achieved levels of resident morale, surgical experience, and impact on family relationships that are comparable to the 24-hour call system. We review here our process for developing an NF call model and the perceptions and experiences of residents, with the goal of providing insight for other residency programs that are considering or instituting NF call systems.
