Introduction. The evaluation of clinical skills is an important part of the medical training. The present article describes the results of a pilot study that was carried out to analyze the feasibility of the implementation of the Mini-Clinical Evaluation Exercise (mini-CEX) in medical students. Subjects and methods. Mini-CEX was used in students from third, fourth and fifth year of Medical School of the University of Barcelona during their clerkship in Internal Medicine, Pneumology/Thoracic surgery, Nephrology/Urology in the academic year 2013-2014. Students completed at least one encounter and several tutors from different departments participated in the study. Results. Thirteen tutors and 27 students participated, with 64 encounters and a mean of 2.4 encounters by student. The mean time of the encounters was 8.4 min (range: 4-60 min) and of the feedback period of 8.4 min (range: 3-30 min). The mean score of students' satisfaction (9.2; range: 6-10) was higher than of the tutors (8.8; range: 7-10). Conclusions. The study showed the feasibility of mini-CEX in medical students regarding the time needed to perform it and the satisfaction of tutors and students with the experience.
