Objective To assess the effect of short-term training workshop of mini clinical evaluation exercise (mini-CEX) for community general practitioner (GP) trainers.Methods Thirty six community GP trainers received half-day training workshop of mini-CEX on September 2012.The GP trainers were interviewed with questionnaire before and after the training program and their video scores were analyzed.Results 47％ (17/36) of GP trainers knew of and briefly understood mini-CEX before the training.42％ (15/36) of them had a rough idea of how to use it but nobody had used it before.All of these trainers hoped to know how to carry out mini-CEX.The vast majority of GP trainers completely or basically understood the standards of evaluation for 7 items of mini-CEX after the training.The accurate rate of 1 iten was close to 50％ in 9-point scale and 5 items exceeded 50％ in 3-rank system.There was significant difference in accurate rates of 4 items between two scoring system (all P ＜ 0.01).Conclusions Community GP trainers recognize the advantage of mini-CEX and have intention to apply it for evaluation of clinical skills in training.The results of short-term intensive workshop are satisfactory,but more training for rating system and practice are necessary.
