OBJECTIVE: To assess the learning process of combining a web-based video of a simulated surgical procedure with a step-by-step checklist of the same procedure in achieving competency of the simulated technique, in this case a newborn clamp circumcision. Fundamental to this particular learning process is immediate mentor step-by-step feedback which specifically follows the procedure's step-by-step checklist. MATERIALS AND METHODS: Pediatric residents naive to newborn circumcision were enrolled (n = 7). A circumcision simulator, instruments, and web access to the learning module were provided. Residents trained independently and then performed two simulations with the mentor. The first simulation was completed with formative scored feedback. The learner then performed a second scored simulation. RESULTS: All learners showed improvement between the first and second simulation (mean 85.3-97.4). All residents achieved competency (96/100 or greater) by the second simulation. On post-procedure surveys, learners demonstrated increased comfort and reduced apprehension in performing the procedure. CONCLUSION: Combining a web-accessible video of a procedure, a checklist, and a simulator followed by a single mentor session with immediate formative feedback which follows the steps of the checklist is a useful method to teach the simulation technique of circumcision. We plan to study if this paradigm is transferable to clinical circumcision.
