Growing requirements to train more dietetic students greatly increase the teaching burden on clinical supervisors. This may be reduced if students can develop basic nutrition assessment skills before they commence clinical placement. To test achievement of these skills by Australian dietetic students, a preclinical objective structured clinical examination (OSCE) was developed. Performance at this OSCE was then compared with the performance at first clinical placement.
An OSCE was developed to test preclinical skills during the third year of a 4-year dietetic degree. Learning outcomes relating to nutritional assessment skills were assessed via a 1-h preclinical examination. Student application of these skills was then assessed after the first clinical placement, when performance was compared with the results at the preclinical OSCE.
One hundred and ninety-three students completed the preclinical OSCE and first clinical placement during the period 2002-2007. A strong relationship was observed for individual student scores at the OSCE and the score achieved at the end of clinical placement (beta = 0.66; 95% confidence interval = 0.46-0.86; P < 0.0001). This relationship was maintained even when outliers were removed. No specific year effect was apparent.
A third-year preclinical dietetic OSCE was found to be a valuable method of formative assessment for assisting dietetic students with the preparation for their first clinical placement. It aided the early identification of those students who are likely to do less well on their first clinical placement.
培养更多营养师学生的需求不断增加，这大大增加了临床导师的教学负担。如果学生能够在开始临床实习之前就发展基本的营养评估技能，那么这种负担可能会减轻。为了测试澳大利亚营养师学生是否达到了这些技能，开发了一个临床前客观结构化临床考试（OSCE）。然后将在这个 OSCE 中的表现与第一次临床实习的表现进行比较。
在为期四年的营养师学位课程的第三年，开发了一个 OSCE 来测试临床前技能。通过 1 小时的临床前考试评估与营养评估技能相关的学习成果。然后在第一次临床实习后评估学生应用这些技能的情况，并将其与临床前 OSCE 的结果进行比较。
在 2002 年至 2007 年期间，有 193 名学生完成了临床前 OSCE 和第一次临床实习。在 OSCE 中的学生个人得分与在临床实习结束时的得分之间观察到很强的相关性（β=0.66；95%置信区间=0.46-0.86；P<0.0001）。即使去除异常值，这种关系仍然存在。没有明显的特定年份的影响。
发现三年级临床前营养师 OSCE 是一种有价值的形成性评估方法，可帮助营养师学生为第一次临床实习做好准备。它有助于及早识别那些在第一次临床实习中表现可能较差的学生。
