Ten high fidelity simulation operating room interprofessional student team training sessions were conducted involving 2 standardized HFS scenarios, each of which was followed by a structured debriefing that targeted tea based competencies. Preband post session mean scores were calculated and analyzed for 15 Likert type items measuring self efficacy in teamwork competencies using the t-test. Additionally, mean scores of observer ratings of team performance after each scenarioand participant ratings after the second scenario for an 11 item Likert type teamwork scale were calculated and analyzed using one-way ANOVA and t-test.
