In-Transit Telemedicine Speeds Ischemic Stroke Treatment: Preliminary Results.

Background And Purpose: Time to treatment is critically important in ischemic stroke. We compared the efficacy and cost of teleneurology evaluation during patient transport with that of mobile stroke transport units.

Methods: Using cellular-connected telemedicine devices, we assessed 89 presumptive stroke patients in ambulances in transit. Paramedics assisted remote teleneurologists in obtaining a simplified history and examination, then coordinating care with the receiving emergency department. We prospectively assessed door-to-needle and last-known-well-to-needle times for all intravenous alteplase-treated stroke patients brought to our emergency departments by emergency medical services' transport, comparing those with and without in-transit telestroke.

Results: From January 2015 through March 2016, 111 stroke patients received intravenous alteplase at study emergency departments. Mean door to needle was 13 minutes less with in-transit telestroke (28 versus 41; P=0.02). Although limitations in cellular communication degraded transmission quality, this did not prevent the completion of satisfactory patient evaluations.

Conclusions: Improvement in time to treat seems comparable with in-transit telestroke and mobile stroke transport units. The low cost/unit makes this approach scalable, potentially providing rapid management of more patients.
