About this Calculator

The Recognition of Stroke in the Emergency Room (ROSIER) scale was created by Nor et al in 2005, first published in Lancet Neurology. It was created to aid first-line ER providers in determining which patients were likely experiencing a stroke, thus expediting referral to an acute stroke team. When compared to similar scales, such as the FAST, the ROSIER scale had greater sensitivity in acute stroke recognition.
