U.K. AI software developer Brainomix has announced that the use of its Brainomix 360 Stroke automated imaging platform for acute stroke assessment was associated with a 100% increase in endovascular thrombectomy (EVT) rates in a clinical study of over 450,000 stroke patients admitted to 107 NHS hospitals throughout England.
The objective of the prospective observational study, reported in Lancet Digital Health, was to evaluate the effect of AI stroke imaging software on endovascular treatment in four stroke networks comprising 26 sites from 2019 through 2023. The investigators believe it is the largest impact evaluation of stroke AI imaging software performed to date.
EVT is a standard of care for patients with large vessel occlusion stroke. AI imaging software is increasingly used to support identification and selection of patients with stroke for this treatment.
Over the five-year period, there was a 100% increase in EVT when the Brainomix 360 Stroke tool was used, compared to a 63% increase at non-evaluation sites. The increase in patient treatment with EVT was most marked in primary stroke centers rather than specialist centers, suggesting that its greatest benefit is at hospitals with fewer specialist physicians. Primary stroke centers also saw a notable reduction of 64 minutes in the door-in-door-out times between admitting a patient and transferring them to a specialized center for EVT.
