Long-term Effectiveness of the Airway Registry at Sydney Helicopter Emergency Medical Service

OBJECTIVE: Prehospital rapid sequence intubation (RSI) is prone to suboptimal documentation. The Greater Sydney Area Helicopter Emergency Medical Service (GSA-HEMS) uses a dedicated Airway Registry (AR) to aid documentation. The AR was only evaluated shortly after its introduction. This first evaluation is followed up to assess the long-term effectiveness of the AR. The secondary objective was to compare the AR with templates in the literature.

METHODS: A retrospective review of electronic records was undertaken to compare completeness of documentation between an immediate postintroduction and a long-term postintroduction cohort. Differences between the two cohorts were tested for significance.

RESULTS: There was no significant difference in documentation for Cormack-Lehane laryngoscopy grade at the first intubation attempt (P = .552) and confirmation of end-tidal carbon dioxide (P = .258). A significant improvement in the documentation of laryngoscopy grade for the second attempt (P = 0) was found. The documentation of intubator details remained at 100% (165/165). The variables collected by GSA-HEMS corresponded well to the literature, but some definitions differ (eg, desaturation).

CONCLUSION: There was no significant change in completeness of documentation for most key intubation variables eight years after the introduction of the AR. GSA-HEMS performs well in registering variables as proposed in the literature; however, variable definitions need to be synchronized.
