The study found that during medical students' clerkship, a self-paced, interactive, multimedia module (SPM) was equally effective as a traditional didactic session (TDS) in applying evidence-based medicine concepts and knowledge to patient care. Both groups of students showed significant improvements in knowledge, attitudes, confidence, and accessing evidence.
OBJECTIVE: To evaluate the effectiveness of a traditional didactic session (TDS) as compared to a self-paced, interactive, multimedia module (SPM) on the application of evidence-based medicine (EBM) skills among medical students during their inpatient pediatric rotation. METHODS: We conducted a randomized controlled trial from June, 2017 to June, 2018 at a quatemary care children's hospital. Students were randomized to TDS or SPM during each 2-week block. All students completed a critical appraisal tool (CAT) of evidence related to a clinical question in a standardized appraisal form and self-reflected about the EBM process. The primary outcome was the numeric score of the CAT derived by using the validated Fresno tool. Secondary outcomes of knowledge, attitudes, confidence, and self-reported behaviors related to EBM were measured using validated surveys. Statistical analysis was performed using Student's t test for CAT scores and mixed-model procedure (PROC MIXED), with subject as random effect and time as repeated measure for the secondary outcomes. RESULTS: One hundred twenty-seven clerkship students were included. Overall, there was no significant difference in mean CAT scores for TDS (n = 59) versus SPM (n = 66) groups (90.3 vs 92.0, P = .65). There were no significant differences between SPM and TDS groups for knowledge (P = .66), attitudes (P = .97), confidence (P = .55), and accessing evidence (P = .27). Both groups showed significant gains in knowledge, attitudes, confidence, and accessing evidence from baseline to postcourse. Improvements in knowledge and confidence were sustained at 3-months. CONCLUSION: A SPM learning module is as effective as a TDS module for application of EBM concepts and knowledge to patient care.
