Abstract
Objective. Emergency cricothyrodotomy (EC) is a lifesaving procedure. Evidence-based assessment of training effects and competency levels is relevant to all departments involved in emergency airway management. As most training uses lowfidelity models, the predictive value of good performance on such a model becomes relevant with regard to performance on a high-fidelity model (cadaver). This requires a valid assessment tool for EC performance. Study Design. Psychometric study on low-fidelity models and human cadavers. Setting. University hospital. Subjects and Methods. An assessment tool was created. Sixteen physicians (7 experienced surgeons and 9 novice physicians) performed an EC on a low-fidelity model and a cadaver. Two blinded raters assessed video recordings of performances using the assessment tool. Results. We found a high interrater reliability, based on a Pearsons r (0.81), and good evidence for validity, based on successfully distinguishing the 2 groups, using an independent samples t test (P<.001). We found a good correlation between performance on a low-fidelity model and the cadaver with an R2= 0.78. Conclusion. The tool for assessing EC competence proved reliable and valid. Performance on a low-fidelity model measured this way is a good predictor of performance in a more lifelike situation.
