An Equitable Electronic Scheduling System for Anesthesiology Residents: A Quality Improvement Project.

Background: Most postgraduate medical education occurs in hospitals in an apprenticeship model with actual patients. Creating a work shift schedule must account for complex factors, including hospital needs, work-hour restrictions, trainee qualifications, and case distribution in order to fairly allocate the resident workload. In this study, we report the first successful implementation of an equitable, computer-generated scheduling system for anesthesiology residents.
Methods: A total of 24 residents at a single, urban training program were surveyed in 2015 to rank work shift difficulty. Shifts were categorized and translated into a weighted point system by program leadership based on the survey results. An automated and modifiable scheduling system was created to incorporate rule-based assignment of prerequisites and evenly distribute points throughout the academic year. Point values were retrospectively calculated in 2014, and prospectively calculated from 2015 to 2018. The equality of variance test was used to evaluate the variation of the SD of monthly average point distributions year-over-year and within each class of trainees.
Results: Year-over-year analysis revealed that post-point system implementation, call point distribution trended toward reduced variance in all 4 years, with significant reductions of 63% in 2016 (SD 4.9, P < .01), and 57% in 2017 (SD 5.8, P < .01). Analyzed by class, first-year trainees' SD decreased by 73% in 2016 (SD 2.5, P < .01), by 67% in 2017 (SD 3.1, P < .04), and 65% in 2018 (SD 3.3, P < .02) compared with the pre-point system year in 2014. The second year clinical anesthesia resident class SD decreased by 56% in 2015 (SD 5.9, P < .01), 41% in 2016 (SD 7.9, P < .02), and 49% in 2017 (SD 6.9, P < .01).
Conclusion: The computerized point system improved work distribution equity year-over-year and within trainee cohort groups.
