Assessment of musculoskeletal examination skills of 4th year medical students using a novel OSCE

Objective: Despite the high prevalence of musculoskeletal complaints presenting to physicians in the United States, there are very few opportunities for University of Michigan clinical medical students to receive formative or summative assessment of their ability to evaluate patients with these complaints. The purpose of this study was to assess 4th year students’ ability to examine and diagnose several common musculoskeletal disorders using a novel objective structured clinical examination (OSCE). Methods: A multidisciplinary team of musculoskeletal specialists developed the content and structure of three OSCE stations focusing on examination of the shoulder, back and knee. For each station, volunteer M4 students were provided a clinical vignette with three possible diagnoses to consider, and were instructed to anticipate physical examination maneuvers or findings that would discriminate between the three diagnoses. Then they would examine a professional patient simulating findings associated with one of the diagnoses and choose their favored diagnosis. Their encounter was directly observed by a faculty member who scored their performance on selected physical examination maneuvers based on a checklist (0 = not done, 1 = partially done, 2 = fully done). Each encounter was recorded to allow for later review by another faculty. Immediate feedback was provided to students at the end of the OSCE, making this a formative as well as summative assessment experience. Faculty received verbal and written instruction on how to score students. IRB exemption was obtained for this study. Results: 44 M4 students participated in the OSCE during the spring of 2012. General performance of M4 students in examining regional musculoskeletal complaints will be reported. Performance of individuals will be correlated with: anticipation of discriminatory features prior to examining the patients; self-assessment on ability to perform the relevant exam and anticipated need to do so in their future career; previous musculoskeletal elective exposure; future career choice; and performance on the M4 Comprehensive Clinical Assessment “Back pain” and “Abdominal pain” stations. Conclusions: Initial validity evidence for a multistation musculoskeletal OSCE will be presented, as will the performance of a sampling of the 2012 graduating UM medical student class. This data will be used as part of ongoing evaluation of the longitudinal musculoskeletal curriculum at the University of Michigan medical school.http://deepblue.lib.umich.edu/bitstream/2027.42/91291/1/MedEdDay2012-poster-monradetal.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/91291/3/MEDC22poster.pd
