Background The Accreditation Council for Graduate Medical Education requires residents to receive milestone-based evaluations in key areas. Shortcomings of the traditional evaluation system (TES) are a low completion rate and delay in completion. We hypothesized that adoption of a mobile evaluation system (MES) would increase the number of evaluations completed and improve their timeliness. Methods Traditional evaluations for a general surgery residency program were converted into a web-based form via a widely available, free, and secure application and implemented in August 2017. After 8 months, MES data were analyzed and compared to that of our TES. Results 122 mobile evaluations were completed; 20% were solicited by residents. Introduction of the MES resulted in an increased number of evaluations per resident ( P = .0028) and proportion of faculty completing evaluations ( P = .0220). Timeliness also improved, with 71% of evaluations being completed during one’s clinical rotation. Conclusions A resident-driven MES is an inexpensive and effective method to augment traditional end-of-rotation evaluations.
