Airway Obstacle Course for Teaching Prehospital Providers Airway Techniques

Early airway intervention is a vital step in the management of critically ill patients. Emergency medical service (EMS) providers are often first in the chain of survival with equipment to manage airway problems that arise. Therefore, it is paramount that they receive thorough training in aspects of airway management. Often, the training providers currently undergo does not reflect the environmental challenges inherent in EMS. Our obstacle course not only offers trainees a situational environment that simulates common challenges associated with the prehospital environment, but also provides a break from traditional tabletop and lecture-based training methods.

An airway obstacle course was created that comprised four different "obstacles". Each obstacle was a patient in a precarious position requiring airway management, and the trainees could manage the obstacles in the order of their choosing. Trainees could choose from four different airway devices based on the local protocol. Once the device was used successfully, it could no longer be implemented in the course, and thus each device was used once. A validated return on the learning model was used for evaluating learning.

Immediately following training, 95.1% (78) trainees felt they were more confident with airway management. Nearly all, 96.4% (79), agreed that the scenarios in the obstacle course were realistic. Participants retained confidence gains in resource management for intubation at the six-month follow-up (p=0.010). In the six months following training, there was a doubling in the number of intubation attempts (24 to 48) and an overall drop in the success rate (75% to 63%). At the six-month follow-up, participants were able to describe specific events where the training helped them with patient management.

The model of an intubation obstacle course as a means of training EMS providers is both realistic to the participants and provides lasting effects to their confidence in resource management skills. Further studies are needed to determine its effects on intubation success rates and patient outcomes.
