Comparison of student performance in therapeutics and communications courses to outcomes of objective structured clinical examinations: A retrospective analysis

Introduction: The objective was to examine the association between course grades and objective structured clinical examination (OSCE) performances in a pharmacy student cohort.

Methods: A retrospective analysis of demographics, final grades in the Therapeutics I through IV and Communications courses, and multiple OSCE scores (therapeutic knowledge and general communication skills [GCS]) was performed for two cohorts.

Results: Female students scored higher than male students on the warfarin OSCE therapeutic knowledge (P = .008) and GCS scores (P = .02). Age was inversely correlated with warfarin OSCE therapeutic knowledge score (P = .001). The warfarin OSCE therapeutic knowledge score was positively related to Therapeutics II final grades (P < .001). The Communications course final grade was positively correlated to the warfarin OSCE faculty-rated GCS score (P = .005). Therapeutics final grades were not significantly related to station scores of a multi-station OSCE (P > .05). The final regression model included gender and Therapeutics II final grade and explained 6% of the variance in warfarin OSCE therapeutic knowledge scores.

Conclusions: A number of significant associations were found between demographics, final course grades, and specific OSCE scores. A regression model was significant, but only explained a low percentage of the warfarin OSCE therapeutic knowledge score variance, suggesting other factors not evaluated had a greater effect on scores. This research suggests that OSCEs play an important role in demonstrating student competency in educational domains other than knowledge and brings forth new data suggesting that age and/or gender may influence OSCE performance.
