Monthly Assignment of Clinic Duty to Internal Medicine Residents
01 Aug 2018 -17:00 - 18:30
Upon receiving their degree, medical school graduates enter residencies or training programs in specific specialties. As part of this training, each intern and resident, collectively called housestaff, must spend one or two half-day sessions a week in their assigned continuity clinic. The exact amount of time is a function of their current monthly rotation. In fact, it is the variable clinic hour requirements that drive the scheduling process, and is what distinguishes this problem from most personnel scheduling problems. From the program director’s point of view, the objective is to both maximize clinic hours and minimize the number of violations of a prioritized set of goals while ensuring that certain clinic-level and individual constraints are satisfied. The corresponding problem is formulated as an integer goal program and a three-phase methodology is proposed to find solutions. After pre-processing, a commercial solver is used to obtain tentative solutions and then improvements are made in a post-processing step. The effectiveness of the methodology is demonstrated by analyzing eight monthly rosters provided by the Internal Medicine Residency Program at the University of Texas Health Science Center in San Antonio. On average, we were able to assign up to 7.62% more clinic sessions with far fewer violations of the goals than were seen in the actual schedules worked.
