The last 30 years have seen tremendous progress in primary and secondary stroke prevention in the United States with better control of hypertension, decreasing smoking rates, antithrombotic treatment for atrial fibrillation, use of statins, and blood transfusions for children with sickle cell disease. 1 In 1996, intravenous tissue-type plasminogen activator was approved for treatment of acute ischemic stroke, 2 and in 2014 to 2015, endovascular treatment of major arterial occlusion, primarily by stent retrievers, was demonstrated to result in better outcomes for patients with ischemic stroke when compared with patients treated with intravenous tissue-type plasminogen activator alone.3 During this same time period, the field of neurocritical care grew tremendously in terms of physician and nurse training, standardization of care, and technology. Finally, standardization and certification of primary and comprehensive stroke centers have improved the quality of acute stroke care and the use of secondary prevention medications when patients are hospitalized for acute stroke.4,5 These cumulative advances have resulted in the decline in stroke mortality rates from the third to the fifth cause of death in the United States. 6 The bulk of these advances have occurred in 2 settingsthe office of primary care physicians who manages stroke risk factors in persons with and without a prior stroke; and the acute care hospital. Yet, the stroke patient follows a complex path from first onset of symptoms to the years after the onset of stroke, and the transitions between the respective places of care along the path represent major challenges and opportunities.
Transition From Place of Stroke Onset to Acute HospitalOne of the first major transitions of care is when emergency medical services (EMS) respond to a 911 call for a potential stroke. EMS personnel assess the patient at the site of the event with input from family or other witnesses to see whether a stroke has occurred. After assessment, EMS has to transport the patient to a hospital for treatment of their potential stroke. Unlike trauma patients, where there is a defined process of triage to various levels of hospital care based on severity of the trauma and prior certification of hospitals regarding level of care, there is no such triage process for stroke patients. Legislation in several states and a policy statement from the American Heart Association (AHA) recommend that patients with a possible acute stroke be taken to a primary or comprehensive stroke certified hospital, 7 but current triage of patients to a given hospital is not based on severity of the stroke.Why is this important? Stroke severity is strongly associated with the presence of large artery occlusions in patients with ischemic stroke, 8 which are most effectively treated with rapidly administered endovascular therapy at regional comprehensive stroke centers. Also, patients with severe hemorrhagic stroke are best cared for in centers with experienced neurocritical care units. 9 Thus, ideally, patients ...
