Evaluation of Optimal Timing of Expert Feedback in a Simulated Flexible Ureteroscopy Course

Simulation-based training (SBT) has become an increasingly popular modality to train novice surgical residents in the face of rapidly increasing innovative surgical techniques across all surgical disciplines. Recent studies have already demonstrated SBT to be effective in helping overcome the learning curve associated with new surgical techniques, especially in junior residents and endoscopic procedures. In addition, it is known that trainees benefit significantly from expert feedback; however, there is a paucity of data looking into the optimal timing of this feedback during SBT. To address this knowledge deficit, an SBT curriculum was developed for junior urology residents to assess optimal timing of feedback during SBT for flexible ureteroscopy (fURS). The SBT course consisted of a pretraining assessment, three independent practice sessions, and a post-training assessment, with residents receiving expert feedback right after their pretraining assessment (early feedback [EF]) or after their final independent training session (late feedback [LF]). Fifteen trainees with similar baseline fURS experience and precourse fURS task performance score participated in the study. There was a significant difference between the pre- and post-task completion times overall (15.2 minutes vs 9.1 minutes, p < 0.001), with no difference between the early or LF groups (p = 0.884). The mean performance scores improved for both groups (18.2 vs 24.2, p < 0.001) with the EF group having a more statistically significant improvement in performance scores than the LF group (p = 0.05), and most (73%) of residents preferred EF. This study demonstrates that an SBT curriculum for fURS is effective for technical skills development among junior trainees, and that EF resulted in marginally better overall scores and was preferred by residents.
