Emergency transport of stroke suspects in a rural state: opportunities for improvement

Time delay is the key obstacle for receiving successful stroke treatment. Alteplase therapy must start within 4.5 hours from stroke occurrence. Rapid transport to a primary stroke center (PSC) or acute stroke-ready hospital (ASRH) by the emergency medical system (EMS) paramedics is vital. We determined transport time and destination data for EMS-identified and -delivered stroke suspects in Arkansas during 2013. Our objective was to analyze transport time and the hospital qualification for stroke care across the state.

The state's 75 counties were placed into 8 geographical regions (R1-R8). Transport time and hospital qualification were determined for all EMS-identified strokes. Each hospital's stroke care status was categorized as PSC, ASRH, a nonspecialty or unknown care facility (NSCF), out-of-state, or nonapplicable designation facilities.

There were 9588 EMS stroke ground transports with median within-region transport times of 29-40 minutes. Statewide, only 65% of EMS-transported stroke patients were transported to either PSC (12%) or ASRH (53%) facilities. One-third of the patients (30.6%) were delivered to NSCFs, where acute stroke therapy may rarely be performed. Regions with the highest suspected-stroke cases per capita also had the highest percentage of transports to NSCFs.

With only a few PSCs in Arkansas, EMS agencies should prioritize transporting stroke patients to ASRHs when PSCs are not regionally located.
