This interventional trial will compare a novel prehospital stroke transport algorithm (OPUS-i) to a traditional prehospital stroke transport algorithm to improve outcomes in rural stroke patients by determining the effect of implementing a data-driven prehospital stroke algorithm on time to and endovascular therapy. The study consists of a multicenter cohort and will last 24 months but individual subject study duration is 90 days.
Stroke is the fifth leading cause of death in the United States (U.S.) and causes one in six deaths from cardiovascular disease. Intravenous thrombolysis (IVT), unless contraindicated, is the standard of care for acute ischemic strokes (AIS) presenting within 4.5 hours of last known well. IVT plus endovascular therapy (EVT) is standard of care for the typically debilitating large vessel occlusion strokes (LVOS), which represent 30% of AIS. However, only a limited number of stroke centers provide EVT. Currently only 12% of all stroke patients are treated with IVT and only 8% of patients are treated with EVT. Therefore, optimizing prehospital systems of care to provide timely IVT and EVT to all patients.
Most stroke patients arrive at the hospital by Emergency Medical Services (EMS). EMS clinicians use various stroke assessment tools to triage patients to the appropriate level of stroke center. Unfortunately, these prehospital stroke screen tools are imprecise and can delay care for LVOS patients. The choice of transport destination may vary by geography. In an urban area, where several stroke centers of varying capability may be concentrated in a small geographical area, there is negligible impact to the healthcare system if an ambulance bypasses the closest hospital for an ESC. In a more rural area, the decision regarding hospital transport destinations has greater implications. Transporting a patient to a farther ESC will result in a longer transport time and take an ambulance out of its primary coverage for a prolonged time. However, transporting rural stroke patients to their local non-ESC may worsen their clinical outcomes by delaying the time to EVT.
Therefore, we propose to implement the novel OPUS-i prehospital stroke transport algorithm to improve outcomes for stroke patients.
