Abstract

Introduction:We created a suturing skills assessment tool that comprehensively defines criteria around relevant subskills of suturing and confirmed its validity.Methods:Five expert surgeons and an educational psychologist participated in a cognitive task analysis to deconstruct robotic suturing into an exhaustive list of technical skill domains and subskill descriptions. Using the Delphi methodology, each cognitive task analysis element was systematically reviewed by a multi-institutional panel of 16 surgical educators and implemented in the final product when content validity index reached ≥0.80. In the subsequent validation phase, 3 blinded reviewers independently scored 8 training videos and 39 vesicourethral anastomoses using EASE (End-to-End Assessment of Suturing Expertise); 10 vesicourethral anastomoses were also scored using RACE (Robotic Anastomosis Competency Evaluation), a previously validated but simplified suturing assessment tool. Inter-rater reliability was measured with intra-class correlation for normally distributed values and prevalence-adjusted bias-adjusted Kappa for skewed distributions. Expert (≥100 prior robotic cases) and trainee (<100 cases) EASE scores from the non-training cases were compared using a generalized linear mixed model.Results:After 2 rounds of Delphi process, panelists agreed on 7 domains, 18 subskills, and 57 detailed subskill descriptions with content validity index ≥0.80. Inter-rater reliability was moderately high (intra-class correlation median: 0.69, range: 0.51-0.97; prevalence-adjusted bias-adjusted Kappa: 0.77, 0.62-0.97). Multiple EASE subskill scores were able to distinguish surgeon experience. The Spearman's rho correlation between overall EASE and RACE scores was 0.635 (P =.003).Conclusions:Through a rigorous cognitive task analysis and Delphi process, we have developed EASE, whose suturing subskills can distinguish surgeon experience while maintaining rater reliability.
