This study was performed to identify factors that impact student performance on a web-based objective structured clinical evaluation (OSCE) that was developed to improve the evaluation process of students who complete a fourth-year surgical clerkship in trauma-critical care.
We created a multiple-choice OSCE with commercially available software. Clinical cases were developed for incorporation into 7 quizzes that were assembled to appear as 1 examination. Students used intensive care unit flow sheets to review data, to develop a systems-based problem list and differential diagnoses, and to produce treatment recommendations.
No difference was noted in a comparison of the mean scores that were achieved by students on a previous paper (essay format) OSCE and the new web OSCE. There was a correlation of student performance on the web OSCE to the National Board of Medical Examiners (NBME) subject examination that had been completed the previous year (r = 0.60; P < .0001). Performance on the NBME subject examination was the only independent factor that affected reporter, interpreter, and manager skills that were assessed by the OSCE (P < .01).
Implementation of a web OSCE resulted in similar performance of the class as compared with performance on the previous paper OSCE. Correlation of student achievement on the web OSCE to the NBME subject examination supported the construct validity of this institutional examination beyond the areas of face and content validity in which OSCEs may excel.
本研究旨在确定影响学生在基于网络的客观结构化临床评估(OSCE)中表现的因素,该评估旨在改进对完成创伤重症监护四年级外科实习学生的评估过程。
我们使用商业软件创建了一个多项选择题OSCE。开发了临床病例,将其纳入7个测验中,这些测验组合在一起形成1次考试。学生使用重症监护病房流程表来审查数据,制定基于系统的问题列表和鉴别诊断,并提出治疗建议。
在比较学生在之前的纸质(论文形式)OSCE和新的网络OSCE上取得的平均分数时,未发现差异。学生在网络OSCE上的表现与前一年完成的美国国家医学考试委员会(NBME)学科考试成绩相关(r = 0.60;P <.0001)。NBME学科考试成绩是影响OSCE评估的报告、口译和管理技能的唯一独立因素(P <.01)。
与之前的纸质OSCE相比,网络OSCE的实施使班级表现相似。学生在网络OSCE上的成绩与NBME学科考试的相关性支持了这项机构考试在结构效度方面的有效性,超出了OSCE可能擅长的表面效度和内容效度领域。
