Evaluation of a longitudinal medical school evidence-based medicine curriculum: A pilot study

BACKGROUND: Evidence-based medicine (EBM) is increasingly taught in medical schools, but few curricula have been evaluated using validated instruments. OBJECTIVE:To evaluate a longitudinal medical school EBM curriculum using a validated instrument. DESIGN, PARTICIPANTS, MEASUREMENTS:We evaluated EBM attitudes and knowledge of 32 medical students as they progressed through an EBM curriculum. The first part was an EBM "short course" with didactic and small-group sessions occurring at the end of the second year. The second part integrated EBM assignments with third-year clinical rotations. The validated 15-item Berlin Questionnaire was administered before the course, after the short course, and at the end of the third year. RESULTS:EBM knowledge scores increased from baseline by 2.8 points at the end of the second year portion of the course (p = .0001), and by 3.7 points at the end of the third year (p < .0001). Self-rated EBM knowledge increased from baseline by 0.8 and 1.1 points, respectively (p = .0006 and p < .0001, respectively). EBM was felt to be of high importance for medical education and clinical practice at all time points, peaking after the short course. CONCLUSIONS:A longitudinal medical school EBM curriculum was associated with increased EBM knowledge. This knowledge increase was sustained throughout the curriculum.
