The Effect of a County Prehospital FAST-ED Initiative on Endovascular Treatment Times
2020
Abstract Background Acute stroke outcomes depend on timely reperfusion. In 3/2017, local EMS agencies implemented a prehospital triage algorithm with hospital bypass and field activation of the neurointerventional team using the Field Assessment Stroke Triage for Emergency Destination (FAST-ED). A score ≥4 bypasses to a comprehensive stroke center (CSC) and a score ≥6 also has the interventional team field activated off-hours. Aim We analyzed effects of this initiative on volume, acute stroke transfers, treatment times, and outcomes and determined the tool's ability to predict large vessel occlusion. Methods Stroke cases brought to our center by EMS during 3/2016-2/2018 were analyzed, which included one year before and after FAST-ED implementation. Treatment times were compared on- vs. off-hours and to those with field activation. Results Of 1153 patients, 761 (67%) were coded as stroke and 235 (20%) underwent reperfusion. Age, sex, race/ethnicity, stroke severity, length of stay, door-to-needle, and 90-d mRS were comparable between periods. Scale compliance was 85%. Concordance rate of ±1 between EMS and calculated score was 53%. Compared to the previous year, door-to-puncture (DTP) improved by 17 min (p Conclusions This prehospital initiative led to faster DTP by up to 33 min. The highest impact was off-hours with field activation. Only 1/3 of activations led to endovascular treatment. FAST-ED≥6 appears to be appropriate for field activation.
