The Mystery Dinner RCA: Using Gamification and Simulation to Teach Root Cause Analysis.

Introduction: Root cause analysis (RCA) is a widely utilized tool for investigating systems issues that lead to patient safety events and near misses, yet only 38% of learners participate in an interdisciplinary patient safety investigation during training. Common barriers to RCA education and participation include faculty time and materials, trainee time constraints, and learner engagement. Methods: We developed a simulated RCA workshop to be taught to a mix of medical and surgical specialties from over 11 GME programs and to third-year medical students. The workshop was a single 90-minute session formatted as a gamified mystery dinner including characters and sequentially revealed clues to promote engagement. Participant satisfaction and subjective knowledge, skills, and attitudes were assessed with a pre/post survey. Results: The workshop was completed by 134 learners between October 2018 and October 2019. The short workshop duration and premade simulation allowed a small number of faculty to train a wide variety of learners in various educational settings. Participants' presurvey (124 out of 134, 92%) versus postsurvey (113 out of 134, 84%) responses showed that attitudes about RCA were statistically improved across all domains queried, with an average effect size of 0.6 (moderate effect); 91% of participants would recommend this course to a colleague. Discussion: A 90-minute, gamified, simulated RCA workshop was taught to medical students and multiple GME specialties with subjective improvements in patient safety attitudes and knowledge while alleviating faculty time constraints in case development.
