Practice-based learning: an appropriate means to acquire the attitude and skills for evidence-based medicine

To evaluate a practice-based, self-directed EBM-course in an undergraduate medical curriculum in terms of EBM attitude and motivation beliefs.

This study was conducted in a 4-week course of the first-year undergraduate medical curriculum, which takes place twice in an academic year. One group of students (n=210) received a normal EBM-module in November. A practice-based EBM-module was implemented in January for another group of students (n=130). We approached all students following the courses for participation in our research project. In a quasi-experimental design, a validated survey was used to assess students' EBM task value and self-efficacy on a 7-point Likert-scale. In the experimental group, complementary qualitative data were gathered on attitude and motivation by open evaluative questions.

Overall response rate was 93,5%, resulting in 191 students in the control group and 127 students in the experimental group. We did not find differences between the groups in terms of EBM task value and self-efficacy. However, the experimental group showed a higher increased perception of the importance of EBM in decision making in clinical practice (60.0% vs 77.2%; χ²(1, N=318) = 8.432, p=0.004). These students obtained a better understanding of the complexities and time-consuming nature of EBM in medical practice.

The practice-based EBM-course helps students to reflect on practice and knowledge critically. Our findings indicate that integrating clinical practice in the undergraduate learning environment fosters attitude and motivation, suggesting that practice-based learning in EBM education may advance student development as a critically reflective practitioner.
