SIMPL OR, short for System for Improving and Measuring Procedural Learning, is a specialized app for evaluating residents' performance after each procedure. Developed by Procedural Learning and Safety Collaborative Inc, this iPhone app is tailored for efficiency and user-friendliness while offering valuable evaluation data. Users, including residents and faculty, can assess residents based on 3 questions and provide formative feedback via dictation. The aggregated data is easily accessible to faculty, enabling them to gauge residents' experience levels with various procedures. This information empowers faculty to have informed discussions with residents, enhancing the customization of teaching and supervision in the surgical setting.
