Can Pediatric Endoscopists Accurately Assess Their Clinical Competency? A Comparison Across Skill Levels

Background: Assessment is critical to support pediatric endoscopy training. Although trainee engagement in assessment is encouraged, the use of self-assessment and its accuracy among pediatric endoscopists is not well described. We aimed to determine the self-assessment accuracy of novice, intermediate, and experienced pediatric endoscopists. Methods: Novice (performed 1000) pediatric endoscopists from 3 North American academic teaching hospitals each performed a clinical colonoscopy. Endoscopists were assessed in real-time by 2 experienced endoscopists using the Gastrointestinal Endoscopy Competency Assessment Tool for Pediatric Colonoscopy (GiECATKIDS). In addition, participants self-assessed their performance using the same instrument. Self-assessment accuracy between the externally assessed and self-assessed scores was evaluated using absolute difference scores, intraclass correlation coefficients, and Bland-Altman analyses. Results: Forty-seven endoscopists participated (21 novices, 16 intermediates, and 10 experienced). Overall, there was moderate agreement of externally assessed and self-assessed GiECATKIDS total scores with an intraclass correlation coefficient of 0.72 (95% confidence interval, 0.55–0.83). The absolute difference scores among the 3 groups were significantly different (P = 0.005), with experienced endoscopists demonstrating a more accurate self-assessment compared to novices (P = 0.003). Bland-Altman plots revealed that novice endoscopists' self-assessed scores tended to be higher than their externally assessed scores, indicating they overestimated their performance. Conclusions: We found that endoscopic experience was positively associated with self-assessment accuracy among pediatric endoscopists. Novices were inaccurate in assessing their endoscopic competence and were prone to overestimation of their performances. Our findings suggest novices may benefit from targeted interventions aimed at improving their insight and self-awareness.
