Introduction: Surgical residency programs must assess technical skills of trainees using both validated and feasible objective measures. OSATS is a survey consisting of a global rating scale and procedure task-specific checklist scores. Validity of OSATS has been demonstrated across multiple specialties, and OSATS have been developed for multiple otolaryngologic surgeries. Simulation-based training for pediatric bronchoscopy (PB) with didactic teaching and demonstration has been demonstrated as an effective and reproducible method to teach the complex psychomotor task of airway foreign body retrieval. This study aims to investigate if incorporation of a surgical video improves knowledge and simulation skills.
Methods: Pediatric surgery trainees (PST) and otorhinolaryngology (ORL) residents were recruited to participate in this study. All trainees were assessed at an annual PB simulation course. Most of the subjects received the training video prior to simulation (psV) while three did not. All subjects were given surveys before and after the PB to assess their knowledge. Residents performed PB simulations and were graded by an attending surgeon based on the OSATS scale.
Results: 5 PST (average PGY 6), and 4 ORL residents (average PGY 2) participated in the PB simulation and OSATS evaluation. 3 PST and 3 ORL residents reviewed the video prior to sim (psV). Overall, PST and ORL trainees scored 4.06 and 3.956 on OSATS, respectively. The psV-ORL residents (N=3) scored an average of 0.177 points higher on their OSATS than the ORL who had not viewed the video (N=1). The psV-PST subjects (N=3) scored an average of 0.695 points less than PST subjects who had not seen the video (N=2). Knowledge pre- and post-surveys were assessed for all trainees. Scores increased by 0.12 on the pre-survey and 0.833 on the post-survey in subjects with video access.
Conclusion: Watching a surgical video OSATS prior to simulation may be beneficial to surgical trainees in regards to skill acquisition. Incorporation of a surgical video may increase knowledge of the procedure for all trainees.
