Importance:
Identifying longitudinal changes in advanced airway management by emergency medical services (EMS) is crucial for understanding practice patterns and optimizing care.
Objective:
To examine the longitudinal trends in endotracheal intubation (ETI) and supraglottic airway (SGA) utilization in a national EMS cohort.
Design, Setting, And Participants:
This retrospective cross-sectional study analyzed 2011 to 2022 data from the ESO Data Collaborative, a national database of US prehospital electronic health records. The study included all 911 EMS events in which advanced airway management was attempted. Data were analyzed from November 2022 to January 2024.
Exposures:
Advanced airway management attempts, including ETI, SGA, and surgical airways.
Main Outcomes And Measures:
The annual percentage of ETI and SGA attempts, stratified by underlying condition (cardiac arrest, nonarrest medical, nonarrest trauma, pediatrics).
Results:
Among 47.5 million EMS activations, 444 041 (mean [SD] age, 60.6 [19.8] years; 273 296 [61.5%] men) involved advanced airway management, including 305 584 (68.8%) that used ETI and 200 437 (45.1%) that used SGA. The overall incidence was 9.3 per 1000 EMS events. In the cardiac arrest cohort from 2011 to 2022, EMS events with ETI attempts decreased from 2470 of 2831 (87.3%) to 40 083 of 72 793 (55.1%) and those with SGA attempts increased from 711 of 2831 (25.1%) to 44 386 of 72 793 (61.0%). In the pediatric subset, there were similarly large decreases in ETI attempts, from 117 of 182 EMS events (97.3%) to 1573 of 2307 EMS events (68.2%), and increases in SGA attempts, from 11 of 182 EMS events (6.6%) to 1058 of 2307 EMS events (45.9%). In the nonarrest medical and nonarrest trauma cohorts, ETI attempts decreased and SGA attempts increased but to a much lower extent.
Conclusions And Relevance:
In this national cross-sectional study of EMS care episodes, there were marked shifts in advanced airway management practices, with the increased use of SGA and decreased use of ETI. These observations highlight current trends in EMS airway management practices.
