EPMO: A novel medical student assessment tool that integrates entrustable professional activities, prime, and the modified Ottawa coactivity scale.

The authors developed a composite WBPA tool that combines the frameworks of EPAs, PRIME, and Modified Ottawa Co- Activity and demonstrated the usability of applying it for learner assessments in clinical settings. Further multicenter studies with cohorts of pre- and post-clerkship students may provide additional validity evidence for the tool.
