Delirium is a common complication of acute ischemic stroke and is linked to poor outcomes. A new risk score, PREDELIS, was developed using data from 14,475 stroke patients admitted to five Austrian stroke units between 2013 and 2021. Eight factors available at hospital admission predicted delirium: previous delirium, chronic alcohol use, age over 70, male sex, infection, high stroke severity, non-lacunar stroke type, and vision or hearing impairment. The score achieved moderate predictive accuracy, with patients scoring 5 or fewer points having a 2.5% risk of delirium, while those scoring 9 or more had a 30.9% risk. The tool can help clinicians identify high-risk patients for targeted prevention.
