Emergency physicians supervise residents performing rare clinical procedures, but they infrequently perform those procedures independently. Simulation offers a forum to practice procedural skills, but simulation labs often target resident learners, and barriers exist to faculty as learners in simulation-based training. Simulation-based curricula focused on improving emergency medicine (EM) faculty's rare procedure skills were not discovered on review of published literature. Our objective was to create a sustainable, simulation-based faculty education curriculum for rare procedural skills in EM. Between 2012 and 2019, most EM teaching faculty at a single, urban, Level 1 trauma center completed an annual two-hour simulation-based rare procedure lab with small-group learning and guided hands-on instruction, covering 30 different procedural education sessions for faculty learners. A questionnaire administered before and after each session assessed EM faculty physicians' self-perceived ability to perform these rare procedures. Participants' self-reported confidence in their performance improved for all procedures, regardless of prior procedural experience. Faculty participation was initially mandatory, but is now voluntary. Diverse strategies were used to address barriers in this learner group including eliciting learner feedback, offering continuing medical education credits, gradual roll-out of checklist assessments, and welcoming expertise of faculty leaders from EM and other specialties and professions. Participants perceived training to be most helpful for the most rarely-encountered clinical procedures. Similar curricula could be implemented with minimal risk at other institutions.
