title: Sink or Night Float: University of British Columbia Radiology Residents' Experience With Overnight Call.
abstract: OBJECTIVE
  In July 2012, in response to residents' concerns regarding the impact of the traditional 24-hour call system on their personal well-being and educational experience, the University of British Columbia Radiology residency program adopted a 12-hour night float system. This shift takes place in the context of increasing concerns, both across Canada and internationally, about resident well-being and the impact of prolonged duty hours on patient care.
  
  
  METHODS
  An anonymous survey was distributed to all 25 postgraduate years 2-5 University of British Columbia radiology residents 12 months after the introduction of night float. This study sought to solicit residents' feedback about these changes and to identify potential future changes to optimize the call system.
  
  
  RESULTS
  The response rate was 100%; 96% of residents were in favor of continuing with night float rather than the traditional call system; 72% of residents reported that their judgement was affected secondary to being on night float. Although most residents described varying degrees of impairment, the rate of acute discrepancies between resident preliminary and attending radiologist final reports decreased by more than half, from 2% to less than 1%.
  
  
  CONCLUSIONS
  The vast majority of our residents were in favor of maintaining the night float call system. Night float had a beneficial effect on the resident educational experience: by eliminating the pre-call morning and post-call day off rotation, residents gained an additional 24 days per year on other clinical rotations.
