To develop and test the validity of an Objective Structured Assessment of Technical Skills (OSATS) tool for breech presentation delivery.
Monocentric prospective study conducted in the Department of Gynecology, Obstetrics, Fetal Medicine and Reproductive Medicine at the University Hospital of Nice. The study consisted of two parts, the development of the OSATS scoring system and its objective validation. Several experts in obstetrics from university hospital centers and private French hospitals were invited to participate in the development phase of the scoring system. For the validation phase, we formed a group of 20 novices and a group of 20 experts, who had to perform a breech presentation delivery on a simulator, according to a standardized scenario. Each participant was filmed and two experts would then evaluate their performance by viewing anonymized videos and using the OSATS score.
The scores obtained by the expert group were significantly higher than those of the novice group, with a total score of 21.73/25 versus 6.95/25 (p < 0.0001), a task-specific score of 87.2/110 versus 44.3/110 (p < 0.0001) and an overall score of 108.93/135 versus 51.25/135 (p < 0.0001), respectively.
The OSATS score developed in this study for breech presentation delivery is a reliable model to assess the competence level in procedural skills using a simulator.
开发并测试用于臀位分娩的客观结构化技术技能评估（OSATS）工具的有效性。
在尼斯大学医院妇产科、胎儿医学与生殖医学科进行的单中心前瞻性研究。该研究包括两个部分，即OSATS评分系统的开发及其客观验证。邀请了来自大学医院中心和法国私立医院的几位产科专家参与评分系统的开发阶段。在验证阶段，我们组建了一组20名新手和一组20名专家，他们必须根据标准化场景在模拟器上进行臀位分娩操作。对每位参与者进行拍摄，然后由两位专家通过观看匿名视频并使用OSATS评分来评估他们的表现。
专家组获得的分数显著高于新手组，总分分别为21.73/25 对比 6.95/25（p < 0.0001），特定任务分数为87.2/110 对比 44.3/110（p < 0.0001），总体分数为108.93/135 对比 51.25/135（p < 0.0001）。
本研究中开发的用于臀位分娩的OSATS评分是一种可靠的模型，可用于评估使用模拟器进行操作技能的能力水平。
