Difficult Laryngoscopy Prediction Score for Intubation in Emergency Departments: A Retrospective Cohort Study.

Objective: Difficult laryngoscopy is associated with difficult intubation, an increasing number of endotracheal intubation attempts, and adverse events. Clinical prediction of difficult airways in an emergency setting was limited in sensitivity and specificity. This study developed a new model for predicting difficult laryngoscopy in the emergency department.
