BACKGROUND: A subset of Entrustable Professional Activities (EPAs) has been developed for general surgery. We aim to contribute validity evidence for EPAs as an assessment framework for general surgery residents, including concurrent validity compared to ACGME milestones, the current gold standard for evaluating competency. STUDY DESIGN: This is a cross-sectional study in a general surgery training program within a tertiary academic medical center. EPA assessments were submitted using a mobile app and scored on a numerical scale, mirroring milestones. EPA score distribution was analyzed with respect to post-graduate year (PGY) level and phase of care. Proportional odds logistic regression identified significant predictors. Spearman rank and Wilcoxon rank tests were used for comparisons with milestone ratings. RESULTS: From August 2018 to December 2019, 320 assessments were collected. EPA scores increased by PGY level. Operative phase EPA scores were significantly lower than nonoperative phase scores. PGY level, operative phase, and case difficulty significantly influenced entrustment scoring. EPA scores demonstrated strong correlation with nonoperative milestones patient care-1, medical knowledge-1, interpersonal and communication skills-2, interpersonal and communication skills-3, professionalism-1, professionalism-3, and practice-based learning and improvement-2 (ρ > 0.5, p < 0.05) and a weaker correlation with operative milestones patient care-3 and medical knowledge-2 (ρ < 0.5, p < 0.05). CONCLUSIONS: The influence of PGY level and operative phase on entrustment scoring supports the validity of EPAs as a formative evaluation framework for general surgery resident performance. In addition, evident correlations between EPA scores and respective milestone ratings provide concurrent validity evidence.
