Filling the Core EPA 10 assessment void: A framework for individual assessment of Core Entrustable professional activity 10 competencies in medical students.

Objectives: The goal of this study was to develop and evaluate a novel curriculum and assessment tool for Core Entrustable Professional Activity (EPA) 10 competencies and entrustment scoring in a cohort of medical students in their emergency medicine (EM) clerkship using a framework of individualized, ad hoc, formative assessment. Core EPA 10 is an observable workplace-based activity for graduating medical students to recognize a patient requiring urgent or emergent care and initiate evaluation and management.

Methods: This is a prospective, pretest-posttest study of medical students during their EM clerkship. Using the Thomas and Kern framework, we created a curriculum of simulation cases about chest pain/cardiac arrest and respiratory distress, which included novel assessment checklists, and instructional videos about recognizing and managing emergencies. Students were individually pretested on EPA 10 competencies using the simulation cases. Two raters scored students using standardized checklists. Students then watched instructional videos, underwent a posttest with the simulation cases, and were scored again by the two raters using the checklists. Differences between pretest and posttest scores were analyzed using paired t-tests and Wilcoxon signed-rank tests.

Results: Seventy-three out of 85 (86%) students completed the curriculum. Mean scores from pretest to final posttest in the chest pain/cardiac arrest and respiratory distress cases significantly improved from 14.8/19 (SD 1.91), to 17.1/19 (SD = 1.00), t(68) = 10.56,  < 0.001, and 8.5/13 (SD 1.79), to 11.1/13(SD 0.89), t(67) = 11.15,  < 0.001, respectively. The kappa coefficients were 0.909 ( = 2698,  < 0.001) and 0.931 ( = 1872,  < 0.001). Median modified Chen entrustment scores improved from 1b (i.e., "Watch me do this") to 2b (i.e., "I'll watch you") for the chest pain/cardiac arrest case ( < 0.001) and 1b/2a (i.e., "Watch me do this"/ "Let's do this together") to 3a (i.e. "You go ahead, and I'll double-check all of your findings") for the respiratory distress case ( < 0.001).

Conclusion: A new directed curriculum of standardized simulation cases and asynchronous instructional videos improved medical student performance in EPA 10 competencies and entrustment scores. This study provides a curricular framework to support formative individualized assessments for EPA 10.
