Abstract:Introduction: Bronchoscopy is a very complex skill, and surgeons seem to differ at learning this skill. In order to minimize patient risk, it is crucial to only enable proficient surgeons to perform bronchoscopies. However, adequate selection and assessment methods do not exist at present. A promising solution would be to include simulator-base prediction of surgical performance. The current study aims at exploring whether bronchoscopy simulator performance can be used to individually assess prospective trainees based on the maximum performance they are expected to reach after training, based on learning curves. By means of this assessment method, it is explored which individuals are more suitable for becoming a bronchoscopist and which individuals will experience more difficulties. First, it was analysed whether learning curves exist in the performance of basic bronchoscopy simulator tasks. Moreover, it was explored whether individual differences exist in acquiring bronchoscopic skills to confirm the need for individualized training. Finally, it was tested whether the simulator tasks together form a reliable test to select prospective trainees based on their performance. Method: Nineteen students took part in a repeated-measure study. Participants had to perform two or three basic bronchoscopy simulator tasks fifteen times each on the GI-BRONCH Mentor TM. Exponential learning curves have been estimated per task and participant. Maximum performance, based on time-on-task, was the primary parameter of interest. Correlations between the asymptote for each task on population-level were calculated. Results: All participants improved performance over time for all three tasks, as the time to complete each trial decreased. Moreover, individual differences in acquiring bronchoscopic skills have been found. The internal consistency between the three simulator tasks was low and highly uncertain.
