This study aimed to develop and validate the OSABSS (Objective Structured Assessment of Basic Surgical Skills), a modified Objective Structured Clinical Examination (OSCE), to assess basic surgical skills in residents.
A developmental study conducted in two phases. Basic skills were identified through literature review and gap analysis. The OSABSS was then designed as a modified OSCE.
This study took place at Alborz University of Medical Sciences in Iran.
The OSABSS was created using Harden's OSCE (Objective Structured Clinical Examination) methodology. Scenarios, checklists, and station configurations were developed through expert panels. The exam was piloted and implemented with residents as participants and faculty as evaluators.
32 surgical residents in gynecology, general surgery, orthopedics, and neurosurgery participated. 22 faculty members were evaluators.
The primary outcome was OSABSS exam scores. Secondary outcomes were written exam scores, and national residency entrance ranks.
The mean OSABSS score was 16.59 ± 0.19 across all stations. Criterion validity was demonstrated through correlations between OSABSS scores, written scores and entrance ranks. Reliability was high, with a Cronbach's alpha of 0.87. No significant inter-rater score differences were found.
The rigorous OSABSS development process produced an exam demonstrating strong validity and reliability for assessing basic surgical skills. The comprehensive station variety evaluates diverse technical and non-technical competencies. Further research should expand participant samples across surgical disciplines.
本研究旨在开发并验证OSABSS（基本外科技能客观结构化评估），这是一种改良的客观结构化临床考试（OSCE），用于评估住院医师的基本外科技能。
分两个阶段进行的一项发展性研究。通过文献综述和差距分析确定基本技能。然后将OSABSS设计为一种改良的OSCE。
本研究在伊朗的阿尔伯兹医科大学进行。
使用哈登的OSCE（客观结构化临床考试）方法创建OSABSS。通过专家小组制定情景、检查表和考站配置。以住院医师为参与者、教员为评估者对该考试进行了试点和实施。
32名妇产科、普通外科、骨科和神经外科的外科住院医师参与。22名教员为评估者。
主要结局是OSABSS考试成绩。次要结局是笔试成绩和国家住院医师入学排名。
所有考站的OSABSS平均成绩为16.59±0.19。通过OSABSS成绩、笔试成绩和入学排名之间的相关性证明了效标效度。信度较高，克朗巴哈系数为0.87。未发现评分者间成绩存在显著差异。
严格的OSABSS开发过程产生了一项考试，该考试在评估基本外科技能方面具有很强的效度和信度。考站种类丰富，可评估多种技术和非技术能力。进一步的研究应扩大外科各学科的参与者样本。
