Algorithmic Imaging Software Speeds Care and Improves Outcomes for Ischemic Stroke at Primary and Comprehensive Stroke Centers

Data from the AI ENRICH trial (NCT03865979), presented at the International Stroke Conference held online March 17-19, 2021, showed use of algorithmic imaging software (Viz LVO; Viz.ai, San Francisco, CA) improved reperfusion rates in ischemic stroke treatment. For individuals with ischemic stroke treated at primary stroke centers (PSCs), arrival-to-transfer time was reduced and for those treated at comprehensive stroke centers (CSCs) door-to-needle time was reduced. 

The average reduction in arrival-to-transfer times at PSCs was 102.3 minutes, a 45% reduction compared with care that did not utilize the software. For individuals whose care was coordinated with the software, there was also an 11.4% improvement in their modified Rankin Scale (mRS) score. At CSCs, treatment of individuals with ischemic stroke caused by large vessel occlusion (LVO), time from arrival to treatment with tissue plasminogen activator (tPA) was reduced by 86.7 minutes and improved rates of revascularization by 10.8%.

“Our two studies show that the incorporation of Viz LVO to coordinate care for ischemic stroke patients is associated with significant time savings across a hub and spoke model and also at comprehensive stroke centers.” said Dr. Hassan. “Because we know that ‘time is brain,’ these improvements in the PSC and CSC settings could lead to significant advances in functional outcomes, reduced mortality and shorter hospital stays.”

“We are so grateful to the research teams, and to all the healthcare providers around the world who have dedicated their careers to improving the lives of stroke patients,” said Dr. Chris Mansi, co-founder and CEO of Viz.ai. “At Viz.ai, that mission is at the core of our work. We want to improve how healthcare is delivered, reducing time to treatment and improving access to care. The magnitude of time saved in these studies demonstrates how intelligent software can be harnessed to significantly reduce disability from stroke.”
