目的 比较分析住院医师出科考试中迷你临床演练评估(mini-clinicalexaminationexercise,Mini-CEX)量表改进前后的评分结果,进而探索更具可靠性的Mini-CEX评分方式。方法 将2016年1月至2017年12月在山东大学齐鲁医院青岛院区参加住院医师规范化培训出科考试的住院医师Mini-CEX成绩作为研究资料,根据Mini-CEX改进前后量表的不同将数据分为两组,分析两组数据的分值分布和离散度。结果 共收集1354份数据,其中Mini-CEX量表改进前686份,改进后668份。改进前的成绩集中分布在满分区域,改进后的成绩均匀分布在6分～8分之间,改进后住院医师成绩的四分位数间距较改进前有所增加。结论 Mini-CEX量表改进前的评价区分度较差,改进后医师成绩分布变得较宽,这可以使评价更接近住院医师的真实情况。

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.
