Use of Moulage to Evaluate Student Assessment of Skin in an Objective Structured Clinical Examination.

PURPOSE: This study investigated the physician assistant (PA) student evaluation of skin and the use of moulage in an objective structured clinical examination (OSCE).

METHODS

Clinical-year PA students participated in an OSCE, taking a history, completing a physical examination, and writing a focused clinical note. The standardized patient's history simulated a primary diagnosis of right-sided carpal tunnel syndrome and an incidental skin lesion consistent with melanoma, only if the student made an inquiry in this replication study. Faculty members' assessments of students' physical examinations were standardized using an agreed-upon rubric. Students completed an anonymous survey on the OSCE experience immediately following the activity.

RESULTS

All students identified the primary diagnosis of carpal tunnel. Sixty-three percent of students verbalized examination of the skin; however, only 38% identified an atypical skin lesion in their clinical note documentation. Of those, only 33% of students referred the patient for biopsy. Most students believed that the use of moulage increased the realism of the standardized patient encounter. Sixty percent of students reported that they noticed a skin lesion but did not believe that it was part of the simulated experience.

CONCLUSIONS

Moulage increased the realism of the OSCE. This study found that the ability of a student to verbalize the evaluation of a particular body system did not necessarily mean that they adequately or correctly assessed that system upon physical examination. Implementation of an OSCE and use of moulage provided an opportunity to explicitly assess student performance related to evaluation and assessment of skin. It provided a mechanism for meaningful, formative feedback of students' performance.
