title: Development and validation of an objective structured assessment of technical skill tool for the practice of vertex presentation delivery.
abstract: OBJECTIVE
  To develop and test the validity of an objective structured assessment of technical skill (OSATS) tool for vertex presentation delivery simulations.
  
  
  METHODS
  Monocentric prospective study conducted in the Department of Gynecology, Obstetrics, Fetal Medicine and Reproductive Biology at the University Hospital of Nice. The study consisted of two parts, the development of the scoring system and then its validation. Experts in obstetrics from several academic institutions 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 performed a childbirth simulation according to a standard scenario. Each participant was filmed and then two experts evaluated their performance with the OSATS score by viewing anonymized videos.
  
  
  RESULTS
  The scores obtained by the expert group were significantly higher than those of the novice group, whether we compared the total score or each part of the score (task-specific or global) independently. We obtained a p value of 0.03 for the total score, p = 0.036 for the task-specific score, and p < 0.001 for the overall score.
  
  
  CONCLUSIONS
  The OSATS score developed in this study for vertex presentation delivery is a reliable mean to assess the medical students' competence in procedural skills using a simulator.
