Implementation of a Mini-CEX Requirement Across All Third-Year Clerkships

Direct observation of medical students performing clinical tasks, such as eliciting a patient history or examining a patient, and the provision of feedback, are foundational to student improvement but have been reported to occur infrequently. The mini clinical evaluation exercise (mini-CEX) is a tool that can facilitate direct observation and feedback. This study assessed the impact of a mini-CEX requirement across all 3rd-year clerkships on student report of direct observation by faculty and objectively measured clinical skills.

A mini-CEX requirement across all 3rd-year clerkships was implemented in the 2012-2013 academic year. The impact of the mini-CEX requirement on student report of direct observation was assessed by end-of-clerkship surveys and Association of American Medical Colleges (AAMC) Graduation Questionnaire (GQ) items on direct observation. The impact on students' clinical skills was assessed by a summative Objective Structured Clinical Examination (OSCE). Pre/post comparisons were assessed with chi-square and Fisher's exact tests.

A mini-CEX requirement had been in place for the internal medicine clerkship, and student reports of direct observation were historically higher for the internal medicine clerkship than for other clerkships. Faculty, residents, and students at each of the clinical sites across all 6 clerkships were oriented to the use of the mini-CEX; the feasibility of its use during usual patient interaction settings and the importance of direct observation and feedback for student improvement were emphasized during these sessions.

Adherence to the mini-CEX requirement was high: 92% of required forms were completed, and 78% of completed forms indicated that specific feedback was given. The proportion of students reporting direct observation of physical examination significantly increased in all clerkships, with the largest relative increase occurring in surgery (from 49% to 87%), χ²(1, N = 225) = 37.70, p < .0001. Significant increases were seen in faculty observation of history taking in pediatrics, surgery, and psychiatry. Direct observation rates also increased on the AAMC GQ items for history taking and physical exam for all clerkships. Failures on the summative OSCE decreased from 12% preintervention to 2% postintervention (p = .0046).

Institution of a mini-CEX requirement was feasible across all 3rd-year clerkships and was associated with a significant increase in student report of direct observation by faculty and a decrease in summative OSCE failure rates.
