Every 40 seconds, someone in the United States has a stroke; the stroke results in a death every 4 minutes. Globally, stroke is a leading cause of death and the leading cause of disability. Emergency treatments to limit the risk of disability are available but must be administered within a brief window of time. Thus, it is vital that emergency medical services (EMS) personnel recognize, stabilize, and transport a stroke patient with a new sense of urgency and medical centers handle these patients on an emergency basis that includes developing acute stroke teams and forming networks with other medical centers to enable rapid evaluation and treatment 24 hours a day, 7 days a week.
Advanced Stroke Life Support ® is a practical, hands-on, 8-hour course that:
- Was developed by experts in stroke, emergency medicine, prehospital care, and nursing education
- Is updated and improved continuously
- Has been used to train thousands of EMS personnel, nurses, and physicians from hundreds of institutions across the U.S. and throughout the world
- Provides a unique neurologic assessment tool-the MEND exam-ideal for both prehospital and hospital use
- Designed to meet the education requirements for Joint Commission certified stroke centers
As first released in 1998, the ASLS® curriculum was designed for EMS responders, and a prehospital-only version remains available. Early in its development, however, at the urging of neuroscience nurses and neurologists, the curriculum was expanded to add hospital-based content. The version that includes in-hospital care in the emergency department and stroke unit, ASLS® for Hospital and Prehospital Providers, is suitable for all audiences. From the onset, ASLS® was intended for widespread dissemination using a train-the-trainer strategy, i.e., preparing others to teach the curriculum with ready-made course materials available for purchase.
A key feature of the ASLS ® curriculum is hands-on skills training, during which instructors simulate stroke syndromes, and learners perform the MEND Examination, a unique neurologic assessment tool developed with the course. Computer-based multimedia skills training, interactive discussions, and didactic sessions are also components of the curriculum.
The major learning goals for all audiences are to:
- Describe why early treatment may result in a marked reduction in risk of disability
- Identify the five main stroke syndromes and relate them to pathophysiology and clinical signs
- Perform focused evaluation to identify stroke, its location and severity, and t-PA contraindications.
These are included, with learning objectives specific to the audience, in the ASLS ® Course Description. Concurrent breakout sessions facilitate teaching both prehospital and in-hospital audiences together (see ASLS ® Course Agendas).
The curriculum incorporates videos to visually demonstrate the neurologic exam on a normal patient and on a patient exhibiting signs that mimic a stroke, as well as characteristics associated with the various stroke syndromes. Teaching points are also enhanced through the use of diagnostic test scans and x-rays, illustrations, and animation.
Efficacy and Outcomes
The efficacy of the ASLS ® course is continuously assessed through written examinations of cognitive skills and course evaluations. A psychomotor skills study with paramedic learners showed:
- Paramedics improve their stroke knowledge significantly after taking the ASLS® course
- Paramedics improve their patient skills significantly after taking the course
- 73 randomly selected paramedics participated in pre- & postcourse "patient" scenarios
- Skills checklist scores for CPSS, MEND Exam, and ED reporting improved significantly.
The ASLS® curriculum is widely used by hundreds of hospitals, fire rescue, ambulance and EMS systems, and educational institutions throughout the United States. Region and statewide implementation has frequently been facilitated by state departments of health, stroke registries, clinical and educational consortia, and professional associations. ASLS® is also taught in Hong Kong and Mexico.
