An objective structured clinical examination (OSCE) assesses clinical competence in a standardised and context related manner. Compared with written tests, OSCE's are more susceptible to reliability errors because of the use of multiple cases and multiple examiners. In the pre-clinical phase of the medical curriculum of the University Medical Centre Utrecht, an OSCE is organised as a medical consult. We evaluated the radiology station.
Four questions were formulated: We analysed the OSCE results of second year medical students in 2004.
Two hundred and sixty-five students were examined in the OSCE in 2004. Ninety-three Students were examined in the radiology station. Cronbach's alpha coefficient for the radiology station was 0.92. The average score for the radiology station was 3.8 (0.87). The average score for the test without radiology was 3.9 (0.32). The range of the average scores for the six different cases was 0.5 (3.6-4.1). The range of the average scores for the five examiners was 1.0 (3.3-4.3).
The internal consistency of the items in the radiology station is good. The average score for the radiology station is similar to that of the other stations. The range of the scores between the different cases was relatively small. The range of the scores between the different examiners was clearly larger.
客观结构化临床考试（OSCE）以标准化和相关背景的方式评估临床能力。与书面考试相比，由于使用了多个案例和多个考官，OSCE 更容易受到可靠性错误的影响。在乌得勒支大学医学中心的医学课程的临床前阶段，OSCE 被组织为医疗咨询。我们评估了放射科站。
制定了四个问题：我们分析了 2004 年二年级医学生的 OSCE 结果。
2004 年，有 265 名学生参加了 OSCE。93 名学生在放射科站接受检查。放射科站的 Cronbach's alpha 系数为 0.92。放射科站的平均得分为 3.8（0.87）。没有放射科的平均得分为 3.9（0.32）。六个不同病例的平均得分范围为 0.5（3.6-4.1）。五个考官的平均得分范围为 1.0（3.3-4.3）。
放射科站项目的内部一致性良好。放射科站的平均得分与其他站相似。不同病例之间的分数范围相对较小。不同考官之间的分数范围明显更大。
