A Telestroke Network Enhances Recruitment into Acute Stroke Clinical Trials

Background and Purpose—Acute stroke clinical trials are conducted primarily at academic medical centers. As a result, patients living in rural areas are excluded from participation, results may not be generalizable to nonacademic settings, and studies may be slow to recruit subjects. Telemedicine can provide rural patients with emergency neurovascular consultation. We sought to determine whether telemedicine facilitates enrollment into acute stroke trials. Methods—We have an established rural “hub and spoke ” telestroke network. From 2005 to 2009, we participated in 2 time-sensitive acute stroke trials: Factor Seven for Acute Hemorrhagic Stroke and Minocycline to Improve Neurological Outcome. Candidates for the 2 trials could be identified at either the hub or at the spokes, with patients presenting to the latter transferred to the hub for enrollment. We analyzed the times from symptom onset to consultation via telemedicine, arrival at the hub, and to initiation of a study drug to determine the impact of telemedicine on study enrollment. Results—Nineteen of 28 subjects enrolled in the 2 trials were identified initially at an outside facility via a telemedicine link. An additional 9 candidates identified by telemedicine could not be enrolled because of transportation time. Arriva
