Objective: To develop and test the validity of an Objective Structured Assessment of Technical Skills (OSATS) tool for breech presentation delivery.
Materials and methods: 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.
Results: 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.
Conclusion: 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.
