Viz.ai created a stroke prevention AI that could speed up life-saving treatment for strokes which was approved for use by the FDA.
Although up to 80% of strokes could be prevented, stroke still ranks as the 5th leading cause of death in the United States. As of now, someone dies of a stroke every 4 minutes in the US, but Viz.ai’s platform seeks to alert professionals earlier so patients can receive prompt treatment and lower the risk of death.
The FDA’s approval of Viz.ai’s artificial intelligence platform for stroke prevention on February 13, 2018 means that this opportunity will be available to patients in the U.S. This makes Viz.ai the first artificial intelligence triage software to be approved by the FDA.
Viz.ai’s solution harnesses deep learning to analyze CTA images and quickly identify any areas that raise suspicion of risk of a large vessel occlusion (LVO) stroke. If any portion of the patient’s brain triggers an alert, the system can directly notify specialists on their mobile devices where they can immediately view the patient’s CTA images.
The AI platform is also integrated with emergency and transportation services so that quick communication and intervention can occur amongst the care team, potentially saving the patient’s life.
Normally, this process would involve multiple phone calls, handoffs, and referrals, according to the company. The impact to treatment time is staggering. Viz.ai states that “every 15 minute delay in reperfusion leads to a decrease in the likelihood of a good outcome by 10%,” and that, with today’s system prior to AI involvement, the time before reperfusion is at a median of 5 hours. Quick detection may increase a presently low 10% intervention rate as well as decrease the time from identification to treatment.
In their press release on Business Insider, Viz.ai notes that stroke costs the “U.S. health system more than $34 billion each year, including health care services, medications and lost productivity.”
Viz.ai’s FDA approval paves the way for regulatory evolution to allow AI deeper into healthcare where it may help prevent and treat disease, all the while helping clinicians and medical teams better manage their resources and priorities, saving everyone time and money.
