客观结构化临床考试在中国大学生医学技术技能大赛中的应用效果分析

Analysis on application effect of objective structured clinical examination in the national undergraduates medical technology skills competition

目的评价第十届中国大学生医学技术技能大赛总决赛临床医学专业五年制赛道客观结构化临床考试(objective structured clinical examination,OSCE)的成绩,为OSCE在今后竞赛中的应用提供参考。方法以42支参赛队伍的OSCE成绩作为研究资料,采用资料分析法,对成绩分布和赛题难度、区分度和信度进行描述。不同类型参赛队伍的OSCE成绩组间比较采用Kruskal-Wallis秩和检验。结果42支参赛队伍的OSCE成绩为160.23(145.03,174.50)分。OSCE总体难度系数为0.60,区分度为0.20,克朗巴赫系数为0.860。来自“双一流”建设高校、省部属共建高校和其他院校参赛队伍的OSCE成绩分别为159.83(156.80,177.68)分、167.98(160.51,174.50)分和146.21(140.25,164.33)分;来自“5+3”一体化、混合组队和五年制参赛队伍的OSCE成绩分别为168.13(159.83,196.51)分、156.47(144.67,166.93)分和157.47(142.80,171.42)分;差异均无统计学意义(均P>0.05)。结论OSCE的赛题质量较好,具备一定优势,OSCE成绩与参赛队伍的院校级别和学生类别均无关。

Objective To evaluate the scores of Objective structured clinical examination(OSCE)in 5-year program track for undergraduates of clinical medicine and to provide suggestions to application of OSCE in the future competition.Methods According to the data analysis,we calculated the distribution,difficulty,discrimination,and reliability.Kruskal-Wallis rank test was used to analyze the relationship between scores and different classification of teams.Results The score was 160.23(145.03,174.50).The difficulty coefficient was 0.60,the discrimination was 0.20 and the Cronbachαwas 0.860.The scores among different teams from double first-class universities,provincial and ministerial universities and other universities were 159.83(156.80,177.68),167.98(160.51,174.50)and 146.21(140.25,164.33)respectively.The scores among different teams from 5+3 integration,mixed and five-year team were 168.13(159.83,196.51),156.47(144.67,166.93)and 157.47(142.80,171.42)respectively.The differences were all not statistically significant(all P>0.05).Conclusions The test questions of OSCE are qualified.It has excellence to be used in the competition.The college levels and training modes of the participating teams have no effect on OSCE scores.
