Abstract: Objective To compare and analyze the results before and after improvement of Mini-clinical examination exercise(Mini-CEX).To explore a more reliable evaluation method of Mini-CEX.Methods Mini-CEX data evaluation from January 2016 to December 2017 was included in this study.All data was divided into two groups based on the results of “before improvement” and “after improvement”.Distribution of scores and interquartile range were analyzed.Results A total of 1 354 sets were included in this study.Specifically,686 sets of score were in the “before improvement”,whereas 668 sets were in the “after improvement” group.The scores before improvement were distributed in full mark,while the scores after improvement were evenly distributed between 6 and 8 points.The interquartile range of the “after improvement” scores was different from the“before improvement”.Conclusions The interquartile range of the Mini-CEX before improvement was poor.The score distribution after improvement became wider.This can make the assessment closer to the real situation of the resident.
