Telestroke is Transforming Emergency Stroke Care
By Dr. Rob Malka
Patients who suffer a stroke are in a race against time. The symptoms occur suddenly, often without warning, and the likelihood of death or permanent disability increases with each passing minute that brain cells are deprived of blood flow. According to the American Stroke Association, stroke remains the fifth leading cause of death and a leading cause of disability in the United States. However, timely treatments such as the administration of “clot-busting” (thrombolytic) medications, and in some cases direct clot removal (endovascular intervention), have been proven to dramatically reduce the risk of death and permanent disability. For these treatments to be effective, hospitals and emergency departments require ultra-fast access to stroke experts who can make an accurate diagnosis and safely implement appropriate management as quickly as possible. In the past, such experts were only available in larger and academic medical centers. However, telestroke is transforming emergency stroke care by providing rapid, 24/7 access to stroke neurologists, even for patients in remote locations or hospitals that do not have access to on-site stroke specialists.
Telestroke availability facilitates rapid diagnosis and treatment. Using high-quality audio/video conferencing technology, neurologists with expertise in the diagnosis and management of stroke can be on-screen at the patient’s bedside within minutes. This is essential for emergency treatment to restore circulation to the brain, as millions of neurons and neuronal connections are lost with each minute that blood flow is impaired. Treatments for acute stroke are most effective at restoring circulation and improving patient outcomes the sooner they are administered. The telestroke neurologist on video can rapidly assess the patient on camera and communicate directly with the patient and family, as well as directly view imaging studies and other patient data in the electronic medical record. This allows for extremely fast response times and comprehensive medical decision-making. Studies show telestroke care can increase the number of patients who receive timely treatment, as well as decrease long-term disability, with a similar impact as an on-site neurologist.1,2
Telestroke programs also provide access to specialized care to a far broader population than is possible with traditional in-person models. Neurologists with expertise in stroke are in short supply, usually staffing hospitals in bigger cities and academic centers. However, strokes affect patients everywhere, including in locations far from such facilities. Telestroke levels the playing field by allowing rapid access to a stroke neurologist anywhere at any time. This improves outcomes and reduces disparity for stroke patients in rural areas who would not otherwise have timely access to such a specialist.3 Facilities that do have on-site neurologists also benefit from integrating telestroke into their coverage, reducing the on-call burden and excessive workloads for those on-site specialists, especially during nights and weekends.
In addition to ensuring 24/7 access to expert stroke care for patients, telestroke neurologist availability helps local healthcare providers, including nurses and paramedics, receive real-time guidance and education during consults. This helps in building the local knowledge base and community awareness for better stroke recognition and pre-hospital care, as well as emergency management.4
In extension of the above, telestroke integration helps to streamline patient care in existing stroke networks with a “hub-and-spoke” model. Patients who live far from a large comprehensive stroke center (the “hub”) often have closer proximity and thus faster access to a smaller local hospital (the “spoke”) where the patient can undergo initial evaluation and treatment. Aside from timely diagnosis and thrombolytic therapy, the telestroke neurologist can provide expert decision support regarding the possible need for transfer to the comprehensive center for endovascular therapy and/or specialized intensive care monitoring. They can even communicate directly with the team at the comprehensive center and provide integral patient data so that the receiving team is immediately ready to proceed upon the patient’s arrival. This paradigm optimizes not only treatment rates and door-to-needle times5 but also patient triage and transfer utilization, reducing the overall cost and efficiency of care.6
Telestroke services have a substantive impact on the management and outcomes of stroke patients, who require emergent access to specialized care and expertise. Telestroke has transformed the landscape of emergency stroke care, providing far-reaching access to rapid and safe diagnosis and treatment, improving timeliness of care, and helping hospitals in all types of communities implement integrated, streamlined, and comprehensive stroke care.
