Stroke triage using the FAST-ED score shortens process times in large vessel occlusion strokes in a physician staffed pre-hospital emergency medical (PHEM) system.

INTRODUCTION

The impact of streamlining algorithms for stroke patients on process times in pre-hospital emergency medicine (PHEM) is not well investigated. We analyzed the changes in pre- and in-hospital process times after implementation of a streamlining algorithm in a physician staffed PHEM system.

PATIENTS

We conducted a prospective observational study and analyzed process times of adult stroke patients attended by emergency physicians (EP) of the city of Göttingen PHEM service after implementation of a streamlining algorithm including stroke triage using the FAST-ED score. Stroke patients with standard emergency treatment attended before the implementation served as a control group. All patients were transported directly to the University Medical Center Göttingen (UMG) and received endovascular therapy (EVT) and/or systemic thrombolytic therapy.

RESULTS

Of 75 suitable patients eligible in the study group, 37 (49.3%) received EVT and were compared to 44 patients in the control group. Pre-hospital process times did not differ significantly. Median door-to-CT time (12 vs 18 min,  = 0.017) and door-to-lysis time (20 vs 24 min,  = 0.005) were significantly shorter in the study group. Door-to-groin time was also shortened in the study group (42 vs 49 min) but not significantly ( = 0.088).

DISCUSSION AND CONCLUSIONS

Our findings indicate that a PHEM streamlining algorithm (namely the FAST-ED score) can significantly shorten in-hospital process times without delaying pre-hospital care. This improved coordination between PHEM and in-hospital emergency medicine (IHEM) may enhance neurological outcomes for stroke patients. Further research is needed to confirm these results and assess their applicability in other healthcare settings.
