Which teaching method is more effective in a communication course – role-playing versus simulated patients, taught by tutors or faculty staff? A randomized trial

Aim: Communicative skills can be taught and trained as part of medical training. In these courses, lecturers or tutors serve as instructors, and students perform interviews with simulated patients (SP) or role-play (RP) with fellow students. The present study was conducted to identify the combination of applied teaching methods that is most effective. Method: n=144 third-year (5th semester) medical students attended a medical history-taking course that consisted of three separate sessions (90 minutes each). Students were randomized into three groups. Groups 1 and 2 received training with SP in sessions one and two, followed by RP training in session three; (teaching by lecturer = SP-Lecturer group vs. teaching by tutor = SP-Tutor group). Group 3 received two sessions of RP training and a SP-based training in session three (teaching by tutor = RP-Tutor group). After completing the course, students had to rate their learning success using a short questionnaire, pass an SP-OSCE station and were supposed to answer exam questions. Results: The OSCE performance of both the SP-Lecturer group (n=28) and the RP-Tutor group (n=44) was significantly better than that of the SP-Tutor group (n=26; p=.018 and p=.041, respectively). All groups reported an increase in self-rated history-taking skills (p<.001). There was no difference between groups in the results achieved on the final exam. Conclusions: Students receiving SP-based teaching benefit more from a lecturer-taught course, while students instructed by tutors benefit more from RP-based teaching. The significant learning progress highlights the great advantage of taking the course as part of medical studies. Further research should aim to determine at which time each teaching method improves learning progress most effectively.
