Assessment of clinical competence involves the assessment of cognition and assessment of clinical performance (behaviour in practice). The limitations of the traditional long case examination (LCE) in the assessment of clinical performance led to its replacement with the objective structured clinical examination (OSCE) by many institutions.
To determine and compare the abilities of the OSCE and LCE to predict candidates' performance in the tests of cognitive knowledge in the fellowship examination of the National Postgraduate Medical College of Nigeria in the Faculty of Surgery.
The results of the OSCE, LCE, written papers, picture tests (PTs), vivas, and the total clinical score (TCS) of surgical residents who took part in the fellowship examination over six consecutive examination periods were compared by using the Pearson's correlation coefficient. A -value less than.01 was considered as significant.
The OSCE had a weak but statistically significant positive correlation (.175) with the LCE. Both the OSCE and LCE had similar correlations with the total written papers (TWP) and PTs. The viva had a higher correlation with the OSCE than the LCE. The TCS when compared with either the OSCE or LCE alone had a higher correlation with most of the tests of cognitive knowledge.
Neither the OSCE nor the LCE showed any superiority over the other in terms of the ability to predict performance in the tests of cognition. The TCS appears superior to either the OSCE or the LCE as a predictor of the candidates' overall knowledge of surgery. Therefore, both the OSCE and the LCE should be retained as part of the examination.
临床能力评估包括认知评估和临床实践表现（实际行为）评估。传统的长病例考试（LCE）在评估临床实践表现方面存在局限性，这导致许多机构用客观结构化临床考试（OSCE）取而代之。
确定并比较OSCE和LCE预测尼日利亚国家研究生医学院外科系专科 fellowship 考试中考生认知知识测试表现的能力。
使用 Pearson 相关系数对连续六个考试期参加专科 fellowship 考试的外科住院医师的OSCE、LCE、笔试、图片测试（PT）、口试成绩以及总临床评分（TCS）进行比较。P值小于0.01被认为具有统计学意义。
OSCE与LCE之间存在微弱但具有统计学意义的正相关（0.175）。OSCE和LCE与总笔试（TWP）和PT的相关性相似。口试与OSCE的相关性高于与LCE的相关性。与单独的OSCE或LCE相比，TCS与大多数认知知识测试的相关性更高。
在预测认知测试表现的能力方面，OSCE和LCE均未显示出任何一方优于另一方。作为考生外科总体知识的预测指标，TCS似乎优于OSCE或LCE。因此，OSCE和LCE都应保留作为考试的一部分。
