Over the last decade, tremendous advancements have been made in the realm of endovascular intervention for acute ischemic stroke. Stent retrieval has been established as the new standard of care for patients suffering from large vessel occlusion or LVO stroke. As a result, early recognition of LVO stroke in the pre-hospital setting has become a priority for EMS systems around the world. In addition, a number of severity based stroke assessment scales have emerged in response to this need. The Field Assessment Stroke Triage for Emergency Destination (FAST-ED) Stroke Severity Scale was developed deliberately for EMS providers to predict LVO strokes in the field. This course describes how to apply the steps of FAST-ED and lists additional key priorities associated with best practices in stroke patient assessment and care by EMS.
