Objective Substantial disparities exist in clinical trial participation, which is problematic in diseases such as lupus that disproportionately affect racial/ethnic minority populations. Our objective was to examine the effectiveness of an online educational course aiming to train medical providers to refer Black and Latino patients to lupus clinical trials (LCTs). Methods The American College of Rheumatology's Materials to Increase Minority Involvement in Clinical Trials (MIMICT) study used an online, randomized, 2‐group, pretest/posttest design with medical and nursing providers of multiple specialties. We exposed intervention group participants to an education course, while the control group participants received no intervention. Controlling for the effects of participant characteristics, including specialty, and professional experience with lupus, we modeled relationships among exposure to the education course and changes in knowledge, attitudes, self‐efficacy, and intentions to refer Black and Latino patients to LCTs. We also examined education course satisfaction. Results Compared to the control group, the intervention group had significantly higher posttest scores for knowledge, self‐efficacy, and intentions to refer Black and Latino patients to LCTs. Both medical and nursing trained intervention group participants had significantly higher mean posttest scores for knowledge and intentions to refer compared to the medical and nursing trained control group participants. Attitude was insignificant in analysis. The online education course, which received a favorable summary score, indicated that satisfaction and intentions to refer were strongly and positively correlated. Conclusion The MIMICT education course is an effective method to educate medical providers about LCTs and to improve their intentions to refer Black and Latino patients.
