Background and Purpose- Endovascular thrombectomy (ET) door-to-puncture time (DTPT) is a modifiable metric. One of the most important, yet time-consuming steps, documentation large vessel occlusion by computed tomography angiography (CTA). We hypothesized that obtaining CTA on board Mobile Stroke Unit direct alert ET team shortens DTPT over 30 minutes. Methods- compared between patients having onboard then subsequent from September 2018 to November 2019 in August 2014 2018, when was not being used. also correlated with change National Institutes Health Scale baseline 24 hours. Results- Median 53.5 (95% CI, 35-67) minutes shorter notification: 41 (interquartile range, 30.0-63.5) versus 94.5 69.8-117.3; P<0.001). on-scene 31.5 28.8-35.5) 27.0 23.0-31.0) (P<0.001). Shorter greater improvement (correlation=-0.2, P=0.07). Conclusions- Prehospital management including on-board substantially DTPT.
