Background: Efficiency in the transfer of patients with ischemic stroke is a vital factor for patient prognosis. A comprehensive stroke center servicing remote areas in south Florida became HEMS direct-from-field capable on October 15, 2020. In some remote areas, the transfer of patients is via ground or air; the severity of the clinical presentation determines the mode. Concern about HEMS overutilization for lower stroke acuities prompted this study. Purpose: The purpose of this project was to evaluate the current HEMS stroke triage process, assess the accuracy of stroke diagnosis, and use this information to improve EMS education to prevent over-triage for stroke. Methods: A retrospective cohort study from October 15, 2020, to July 31, 2021, collected HEMS adult stroke alert data and compared it to the prior year's summary ground EMS (GEMS) stroke alert data. Using HEMS transportation logs, presenting stroke symptoms and pre-hospital assessment were abstracted. In addition, we evaluated initial NIHSS, downgrade rate, stroke diagnosis percentage, treatment rate, and times. Results: The analysis included a total of 52 HEMS stroke alerts. Assessment tools utilized by HEMS included the Cincinnati stroke scale (4%) and the FAST-ED (37%); the majority of cases (59%) did not document a stroke assessment tool. The median NIHSS was 10, with 37% presenting with a score <6. Respectively, 6% and 15 % of cases were downgraded upon arrival and after CT imaging. Significantly (p<.001), more HEMS cases were diagnosed as a stroke (69%) compared to GEMS (57%). Stroke treatment rates remained similar (HEMS=23%; GEMS=23%). Median door-to-needle times were significantly faster for HEMS (15min) than GEMS (25min) (p<.05). Median door-to puncture times were significantly faster for HEMS (61mins) than GEMS (72mins) (p<.05). Conclusion: With low downgrade rates and high diagnosis accuracy, the current HEMS triage process, although not consistently documented, accurately detects stroke, even for low acuity cases. Patients arriving via HEMS receive equal access to stroke treatment with significantly faster treatment times, ensuring the best possible prognosis. EMS educational efforts should focus on improving documentation compliance.
