There are various tele-health programs created by The Veterans Health Administration including a clinical video tele-health (CVT) system. This system allows direct patient care of veterans by neurologists. The University of South Carolina implemented a web-based tele-stroke program in which acute ischemic stroke patients were treated in the Emergency Department (ED) of rural hospitals by neurologists, after consulting with rural ED physicians. With growing technology and popularity of tele-neurology, there are now international collaborative efforts in tele-medicine that are looking to be adapted to tele-neurology. Thus, tele-neurology can provide quality neurological care with patient satisfaction, as well as time and cost savings. The tele-stroke group established by TRUST-tPA trial (Therapeutic Trial Evaluating Efficacy of Telemedicine (TELESTROKE) of Patients With Acute Stroke) has 10 community hospital-emergency rooms that were connected to a stroke center. It was found that tele-stroke is appropriate in places where there is no way for a patient to access a stroke unit within a 4.5-hour time window. Like other tele-neurology subtypes, tele-epilepsy and pediatric tele-neurology also offer more follow-up care to people of remote areas which have limited access. There are other subtypes like mental health, chronic neurological care, and hospitalist which are very effective in improving outcome and quality of life of people living in remote areas. Tele-neurology has effectively reduced travel costs and times; there is high patient satisfaction and reduced disparity for general and specialized neurological care. But there are certain limitations like large equipment costs, certain bandwidth requirement, and trained staff to use the equipment. Transmission of patient information using public internet raises the concern of legality. There should be sufficient encryption to satisfy the Health Insurance Portability and Accountability Act (HIPAA) requirements to ensure patient confidentiality and safety of personal data.
The adaptation of tele-neurology is a powerful and innovative way to enhance healthcare in areas with a shortage of specialists. Implementation of this tool is limited due to cost burden, lack of expertise to implement necessary technology, legal litigations, and suitable financial and professional incentives for the users. This review focuses on the trajectory of utilization and the issues to be addressed in order to provide the full benefits of tele-neurology to undeserved communities in the future.
