Abstract
ObjectiveTo evaluate the benefits of simulation to teach flexible bronchoscopy.Study DesignA prospective cohort study to assess the bronchoscopic skills of residents in an otolaryngology training program using a commercially available bronchoscopy simulator.SettingTertiary care otolaryngology residency program.MethodsThirty-two otolaryngology residents and 4 expert faculty across 2 academic institutions were assessed on 3 flexible bronchoscopy tasks: diagnostic bronchoscopy, foreign body removal, and tracheal lesion biopsy. Performance was evaluated with a modified version of the validated Bronchoscopy Skills and Tasks Assessment Tool. At 1 of the 2 academic institutions, an additional tool was implemented to evaluate the simulator.ResultsThere was a correlation between postgraduate training year and time taken to complete tasks, including bronchoscopy, foreign body extraction, and passing through the glottis (P < .001, P = .04, and P < .01, respectively). There was a significant difference between residents and faculty laryngologists for a range of skills and tasks, including percentage of time in middle lumen, contact with bronchial walls, inadvertent esophagus entry, and biopsy of healthy tissue (P < .001, P = .003, P < .001, and P < .001). Additionally, increasing postgraduate level was correlated with a higher percentage of time in the center of the lumen and reduced time to task completion (P = .05 and P < .001). Of 32 residents, 20 evaluated the simulator on its realism, with an average score of 4.1 of 5.ConclusionThe commercially available flexible bronchoscopy simulator provides a valid assessment of bronchoscopic skill and is a useful tool for practicing bronchoscopy in a safe, controlled environment.Level of EvidenceIndividual cohort study.
