Construct Validity of the Simbionix Bronch Mentor Simulator for Essential Bronchoscopic Skills

Background: Although simulation-based bronchoscopy has been shown to be an effective training modality, formal assessment should still be performed as new technology emerges. We sought to validate a simulator in essential bronchoscopic tasks, and survey perceptions of bronchoscopists on simulation. Methods: A cohort study at 2 medical centers used 3 groups to assess construct validity of the Simbionix Bronchoscopy Simulator: 7 first-year fellows with 1000 bronchoscopies each (expert). Participants were tested in 4 tasks (1: scope manipulation, 2: guided anatomic navigation, 3: airway anatomy, and 4: lymph node anatomy). Participants were scored and surveyed on their impressions of simulation. The means and Kruskal-Wallis test among groups were compared by task item (P
