Knowledge and attitudes towards evidence-based medicine of mentors in general practice can be influenced by using medical students as academic detailers.

BACKGROUND Regular use of evidence-based medicine (EBM) among general practitioners (GP) is insufficient. OBJECTIVE To analyse whether knowledge and attitudes about EBM can be improved among mentors in general practice by involving sixth-year medical students as academic detailers. METHODS An interventional non-randomized before-and-after study included 98 GPs (49 in the intervention group of mentors and 49 controls) and 174 medical students attending family medicine clinical rotations. A telephone survey on knowledge and attitudes towards EBM was conducted among participating physicians before, and six months after the rotation. During the rotation, each mentor chose two cases from real life, and the students' task was to form an answerable clinical question, find the evidence-based answer and to write a brief report. The mentor reviewed the report and discussed it with the student. RESULTS Students' EBM detailing intervention led to significant improvement in knowledge and attitudes about EBM in the intervention group of mentors in general practice compared to control GPs (relative increase in knowledge was 20 ± 46.9% vs 6 ± 12.1%, respectively; P = 0.042). Among participants with Ph.D. or specialization in family medicine, the observed effects of the intervention were similar as in the total sample, and statistically significant, but not in the group of participants with neither scientific degree nor specialization in family medicine. CONCLUSION Knowledge and attitudes of GP mentors towards EBM can be improved by involving medical students as academic detailers. Further studies should explore the effectiveness of this method among GPs that are not mentors, and who do not have a specialization or research degree.
