Learning Gain and Skill Retention Following Unstructured Bronchoscopy Simulation in a Low-fidelity Airway Model

Background: Simulation is invaluable for bronchoscopy training. Studies report improved procedure time, dexterity/technique, and trainee satisfaction supported by low-fidelity and high-fidelity simulators in structured-training programs. We sought to determine (1) Learning-gain in bronchoscopic dexterity after a single 45-minute unstructured exposure using a low-fidelity simulator. (2) Whether acquired skills are maintained 8 weeks later, during which trainees receive no interim exposure to simulation or clinical bronchoscopy. Methods: Using a low-fidelity model, medical students were assessed for bronchoscopicdexterity before and after an unstructured, self-directed 45-minute simulation. Bronchoscopic dexterity was assessed according to: (1) Ability to enter a target-bronchus within a specified time. (2) The modified Bronchoscopy Skills and Tasks Assessment Tool (mBSTAT). Scores were compared at baseline, postsimulation, and 8 weeks postsimulation. Individual domains of the mBSTAT were compared with identify specific skills demonstrating more significant deterioration. Results: Twenty-eight medical students completed the initial-simulation session. Fifteen returned at 8 weeks. Statistically significant improvement in bronchoscopic-skills was observed immediately following the simulation session (mBSTAT scores 3.7±1.2 pretest vs. 7.0±0.9 posttest, P
