Feasibility of a Multi-Center Respiratory Therapist Endotracheal Intubation Study

Background: Respiratory therapists (RTs) have historically performed safe and effective intubations, yet there are limited multi-center data assessing their intubation performance. Multi-center data can be used to compare RT intubation performance to that of other professions and identify quality improvement opportunities at hospitals where RTs perform intubation. We aimed to explore the feasibility of a multi-center collaborative to evaluate RT intubation outcomes.

Methods: A data collection tool was developed by the authors and implemented at two institutions. Following institutional review board approval at each center and completion of data-use sharing agreements, data were collected between May 25, 2020-April 30, 2022, and combined for analysis. Descriptive statistics were used to compare overall success rate, first-attempt success rate, adverse events (AEs), and type of laryngoscopy.

Results: There were a total of 689 intubation courses where RTs made an attempt, 363 from center A and 326 from center B. Center A captured 85% of all RT intubation courses, and center B captured 63%. Overall, RTs were successful in 98% of attempts. RTs made 86% of initial attempts. The most common indications for intubation were cardiac arrest (42%) and respiratory failure (31%). Videolaryngoscopy was used during 65% of initial attempts and was associated with higher first-attempt success rate, higher overall success rate, and fewer AEs. Airway-related adverse event rate was 8.7%; physiologic AE rate was 16%, and desaturation rate was 11%.

Conclusions: A collaborative examining RTs intubation performance was successfully initiated at 2 separate facilities. Intubations performed by RTs had a high success rate, with AE rates comparable to published results from other types of providers.
