Vertical integration has been extensively implemented across medical school curricula but has not been widely attempted in the field of biochemistry. We describe a novel curricular innovation in which a near-peer learning model was used to implement vertical integration in our medical school biochemistry course. Senior medical students developed and facilitated a case-based small group session for first year biochemistry students. Students were surveyed before and after the session on their attitudes about biochemistry, as well as the effectiveness of the session. Prior to the session, the students believed biochemistry was more important to understanding the basic science of medicine than it was to understanding clinical medicine or becoming a good physician. The session improved students' attitudes about the importance of biochemistry in clinical medicine, and after the session they now believe that understanding biochemistry is equally important to the basic sciences as clinical medicine. Students would like more sessions and believe the senior student facilitators were knowledgeable and effective teachers. The facilitators believe they improved their teaching skills. This novel combination of near-peer learning and vertical integration in biochemistry provided great benefit to both first year and senior medical students, and can serve as a model for other institutions.
