Introduction
vessel occlusion, acute ischemic stroke, AIS
Prompt endovascular thrombectomy (EVT) can dramatically improve outcomes in patients with large vessel occlusion (LVO) acute ischemic stroke (AIS); however, its efficacy is time dependent.Artificial intelligence (AI)–enabled LVO AIS screening coupled with Health Insurance Portability and Accountability Act-compliant group messaging may improve treatment times.To determine the impact of AI-enabled automated LVO AIS detection and workflow enhancements on hospital arrival to EVT initiation, we performed a randomized stepped-wedge clinical study. We chose this design to overcome the impracticality of randomizing at the individual patient level but retaining a robust means to evaluate this intervention.
