Interactions within stroke systems of care: a policy statement from the American Heart Association/American Stroke Association.

In the United States and other parts of the world, various cities, states, and regions are developing multitiered systems for the care of patients with acute stroke. These systems often involve a range of healthcare components supported by various rules and regulations. The present policy statement will put forth concepts and elements for stroke systems of care that are intended to optimize patient care and management processes and improve patient outcomes, are practical to implement, and are supported by existing clinical data or expert consensus opinion. We will also make policy recommendations for the key elements of a stroke system of care. The public health implications of stroke care in the United States and worldwide are profound. Stroke is currently the fourth-leading cause of death in the United States and a major cause of long-term disability. Advancing age is a major risk factor for stroke, and the demographics of the US population and elsewhere reflect a continued growth of the aging population, with a resulting increase in the absolute incidence and prevalence of stroke.1 Improved stroke systems of care can ensure proper treatment of these patients and a reduction in death and disability. This is consistent with current American Heart Association and Centers for Disease Control and Prevention Healthy People 2020 public health goals and initiatives.2 There are several new care paradigms and technologies that are emerging as important elements of a stroke system of care. These include the development and proliferation of various levels of stroke centers; the expanded use of telemedicine technologies; advanced medical, endovascular, and surgical interventions; and comprehensive rehabilitation strategies and programs. Prehospital care and triage and the efficient transfer of patients between hospitals are also key components of stroke systems. The present …
