TUH’s medical workforce team was responsible for creating medical on-call rosters for almost 90 junior doctors. The manual process of generating these quarterly rosters was complex and time-consuming, requiring at least 12 person weeks per year. There were also complex requirements and rules to consider which made ensuring roster fairness difficult and resulting in complaints from doctors. Three rosters were needed for 30 registrar (senior grade), 30 SHO (middle grade) and 26 interns (foundation grade) doctors, four times per year. Requirements included:
- Roster Fairness objectives to be met including even distribution of day, night, and weekend call shifts.
- Over 20 constraints included: avoiding consecutive weekends, ensuring required rest day gaps between call to meet European Working Time Directive (EWTD) regulations, doctors from the same specialty not on call on the same day or near same day, plus other specialty and consultant specific restrictions.
