To determine optimal prehospital routing for suspected stroke based on different routing strategies including hospital performance data.
Utilized a decision-analytic model to evaluate routing decisions based on AHA recommendations, a base model, and an enhanced model incorporating real hospital performance data.
Generated 500 pick-up locations with 800 patient profiles, resulting in 400,000 patient-location scenarios.
Conducted 1000 simulations for each routing strategy to identify optimal destinations.
56.1% of routing destinations differed from AHA recommendations in the base model, while 63.1% differed in the enhanced model, suggesting preference for faster-reperfusion hospitals.
Higher stroke severity and greater likelihood of large vessel occlusion correlated with aligned recommendations.
