Abstract WMP1: Implementation of a Telestroke Program Based on a Smartphone Application

Background: The increasing demand and shortage of experts to evaluate and treat acute stroke patients has led to the development of remote communication tools to aid stroke management. We aimed to describe the experience of the Brazilian Stroke Network in the implementation of a telemedicine stroke program using a low-cost smartphone application system (JOIN App, Allm, Japan) for rapid sharing of clinical and neuroimaging patient data. Methods: We evaluated the initial experience of the telestroke program using a smartphone app measuring its feasibility, safety and speed in the acute stroke decision-making process, with a particular focus on intravenous thrombolysis. The App was implemented in hospitals without neurologists available for acute stroke evaluation and was connected with a stroke team to support the decision for thrombolysis. We analyzed the times of acute treatment and safety through the rate of symptomatic intracranial hemorrhage (sICH) in 24hours. The program was implemented as part of the partnership with the Angels Initiative in Brazil supported by Boehringer Ingelheim to improve stroke care across the globe. Results: The telestroke program started in May 2019 and since then 7 hospitals, in 5 Brazilian states, were included. Only 2 of these hospitals had previous experience with stroke thrombolysis. In all hospitals, the patients were assisted by emergency physicians with eventual support of local neurologists. The telestroke program was activated for 58 patients. The median age was 68yo (IQR58-72), 47% were female and the baseline NIHSS was 11 (IQR8-16). In 69% of the activation the diagnosis was ischemic stroke (IS), 7% hemorrhagic, 5% TIA and 28% other diagnosis. Thrombolysis was suggested in 48% of all evaluations (70% of IS patients). A total of 53% of IS were actually treated with thrombolys. The response-time of the stroke experts was 2.6 minutes (2-6), door-to-CT scan 20min (15-31) and door-needle time 59min (27-81). None of the patients had sICH. Conclusion: In a telestroke program using a smartphone App, thrombolysis performed by emergency physicians was feasible and safe. This mobile low cost technology can increase the possibility of patients with stroke to receive treatment in regions without neurologists across the globe.
