Validation of the Ultimate Stroke Scale (USS): A standardized tool for automated large vessel occlusion screening.

ABSTRACT: BackgroundPrehospital stroke screening for large vessel occlusions (LVOs) varies across institutions. This study compares manual stroke scale calculations against e-calculated scores using the Ultimate Stroke Scale (USS), a software automating multiple screening scales from a modified National Institutes of Health Stroke Scale (NIHSS) with a hand grip. The USS aims to streamline screening by computing multiple validated stroke scales simultaneously to enhance predictive value.MethodsWe applied eight stroke screening scales (NIHSS; Balance, Eyes, Face, Arms, Speech, and Time [BE-FAST]; Vision, Aphasia, Neglect; Los Angeles Motor Scale [LAMS]; Face, Arm, Speech, Time, Eye Deviation and Denial/Neglect [FAST-ED]; Emergency Medical Services Rapid Arterial oCclusion Evaluation [EMS RACE]; 3-Item
