Number of Intubations and the Attainment of Emergency Medicine Airway Milestone Level 4 Sub-competencies

A study of the number of intubations and how they relate to emergency medicine airway milestones was carried out using simulation-based cross-sectional approach. 45 residents each completed two airway-based simulation scenarios. Information on demographics, past experience, scenario performance was collected from all participants. Prior experience demonstrates that with the exception of intubating laryngeal mask airway placement, learners in our program are accumulating increasing numbers of total and different types of intubation scenarios. Additionally, the distributions of learners along the global rating scale for both the anticipated difficult airway (ADA) and the unanticipated difficult airway (UDA) scenario revealed significant differences between the program years. Using logistic regression analysis, we found that the number of training attempts required for achievement of the graduate level airway milestone sub competency is more nuanced than those currently outlined. Each type of intubation scenario (ADA and UDA) required a unique skill set different than the accumulation of raw intubation numbers
