Opioid use disorder and motivational interviewing: Training physician assistants for the epidemic.

OBJECTIVES:(1) To evaluate the effectiveness of a curriculum on physician assistant (PA) students' knowledge about opioid use disorder (OUD) treatment and management and (2) present student satisfaction with the curriculum. METHODS:Three cohorts of PA students completed pre- and post-intervention questionnaires about their knowledge of motivational interviewing (MI) for OUD. One cohort of students completed the 11-item questionnaire without exposure to the intervention (control group). Students' satisfaction with the curriculum was assessed as was their pre- and post-intervention knowledge about using MI for OUD. Bivariate statistical tests were used to analyze the quantitative data. RESULTS:Three hundred complete and usable responses were obtained from the four cohorts of PA students (n = 300, 87.7 percent response rate). The intervention groups answered a higher number of items correctly (median = 7) than the control group (median = 6, Wilcoxon sign test M = 31, p < 0.0001). Among the intervention group, there was not a statistically significant between cohort difference on: (1) the number of identical pre- and post-intervention questionnaire items answered correctly (Chi-square = 3.77, DF = 2, p = 0.15), and (2) the total number of items answered correctly on the post-intervention questionnaire (Chi-square = 0.32, DF = 2, p = 0.85). Student comments suggest students were supportive of the curriculum, with improvements noted on how to deliver the material. CONCLUSIONS:An educational intervention using MI for PA students was found to be valuable, and students who completed the intervention had greater knowledge about using MI with OUD patients than those who did not complete the training. The size of the effect was small, and more research on the curriculum is necessary prior to widespread adoption.
