This protocol included the 5 warning signs of stroke (ASA score: American Stroke As-sociation. Warning Signs 2008. www.strokeassociation.org), in order to better identify patients with a suspicion of stroke. The aim of this study was to evaluate the added value of this protocol in the management of these patients Methods: A prospective study was implemented in a dispatch centre from 2/10/2011 to 6/1/2013. This emergency medical dispatch centre is located in Paris area for an urban population of 1.5 Mil-lion inhabitants. EMD initiated the call and measured the ASA score, and then transferred the call to a Medical Doctor (MD) that took the final decision to refer to a stroke centre, after interviewing callers. All 1264 calls with a suspicion of stroke have been included. Calls have been analysed according to referral to a stroke unit or not. Age, gender, ASA score, delay from onset of symptoms to call were collected. Results: Patients referred to a stroke centre were younger and called earlier. The ASA score mea-surement and gender are not significantly associated to the decision to refer to a stroke centre. When referred to a stroke centre, more than 87% of them where admitted. Conclusion: in this study, ASA score did not have an impact on the decision to refer patients to a stroke centre. This score was greater than 0 in almost 80% of cases. Only age and delay from onset of symptoms to call are significantly associated to the decision to refer to a stroke centre.
