Background: Acute ischemic stroke (AIS) is one of the leading causes of death in Chile. Intravenous thrombolysis (IVT) is an effective treatment. Geographical barriers and lack of specialists limit its application. Telemedicine can overcome some of these pitfalls.
Aim: To describe the implementation and results of AIS treatment by telemedicine at the TeleStroke Unit (TeleACV) of the Southern Metropolitan Health Service, connected with seven hospitals in Chile.
Material And Methods: Descriptive analysis of a prospective tele-thrombolysis data-base that covers from 2016 to 2018, with an emphasis in the last year.
Results: During the analyzed period, seven remote telemedicine centers were activated as far as 830 kilometers on a continental level from the reference center and up to 3,700 kilometers on an island level. There were 1,024 telemedicine consultations, 144 (14%) of them resulted in an IVT treatment. During 2018, 597 tele-consultations were made, thrombolysis was done in 115 (19%) patients aged 66+-13 years; 54 (46.6%) being female. The median admission National Institute of Health Stroke Scale was 8 (interquartile range (IQR) 5-14). The median door-to-needle time was 56.5 (IQR 44.8-73.3) minutes; 60% of patients were treated within 60 minutes. Eight patients (7%) were referred for a subsequent mechanical thrombectomy to a center of greater complexity. Symptomatic intra-cranial hemorrhages occurred in four treated patients (4%). One patient had a systemic bleeding.
Conclusions: The Telestroke Unit achieved a high rate of IVT and good door-to-needle times. This may help to overcome some of the geographic barriers and the specialist availability gap in our country.

Background: Acute stroke treatment is time-critical. To provide qualified stroke care in areas without 24/7 availability of a stroke neurologist, the concept of teleneurology was established, which is based on remote video communication through telemedicine organized by telestroke networks. Data on the effectiveness and efficiency of stroke treatment via teleneurology is very scarce and is therefore partly questioned in the healthcare sector.

Article Synopsis
- * Many low- and middle-income countries (LMICs) are beginning to establish telestroke services, indicating a potential shift in access to specialized stroke care.
- * The analysis identified significant variations in network structures and technologies used, with 75% employing real-time video and image transfer, and a focus on quality monitoring in 74% of networks.

Background: Telemedicine provides specialized medical expertise in underserved areas where neurological expertise is frequently not available on a daily basis for hospitalized stroke patients. While tele-consultations are well established in acute stroke assessment, the value of telemedicine-based ward-rounds in the subsequent in-patient stroke management is unknown.
Methods: Four telemedicine stroke networks in Germany, implemented in eight out of 16 federal states, participate in this prospective observational multi-center study.

To evaluate our two non-machine learning (non-ML)-based algorithmic approaches for detecting early ischemic infarcts on brain CT images of patients with acute ischemic stroke symptoms, tailored to our local population, to be incorporated in our telestroke software. One-hundred and thirteen acute stroke patients, excluding hemorrhagic, subacute, and chronic patients, with accessible brain CT images were divided into calibration and test sets. The gold standard was determined through consensus among three neuroradiologist.

Purpose Of Review: Recent stroke treatment advances have necessitated agile, broad-scale healthcare system redesign, to achieve optimal patient outcomes and access equity. Optimised hyperacute stroke care requires integrated pre-hospital, emergency department, stroke specialist, radiology, neurosurgical and endovascular neurointervention services, guided by a population-wide needs analysis. In this review, we survey system integration efforts, providing case studies, and identify common elements of successful initiatives.
