Defining the Learning Curve for Paramedic Student Endotracheal Intubation

Background. Proficiency in endotracheal intubation (ETI) is assumed to improve primarily with accumulated experience on live patients. While the National Standard Paramedic Curriculum recommends that paramedic students (PSs) perform at least five live ETIs, these training opportunities are limited. Objective. To evaluate the effects of cumulative live ETI experience, elapsed duration of training, andclinical setting on PS ETI proficiency. Methods. The authors used longitudinal, multicenter data from 60 paramedic training programs over a two-year period. The PSs reported outcomes (success/failure) for all live ETIs attempted in the operating room (OR), the emergency department (ED), the intensive care unit (ICU), andother hospital or prehospital settings. Fixed-effects logistic regression was used to model up to 30 consecutive ETI efforts by each PS, accounting for per-PS clustering. For each patient, the authors evaluated the association between ETI success andthe PS's cumulative number of ETIs, adjusted ...
