Method: Patients admitted with acute stroke during office hours and possibly also during daytime in weekends in Bispebjerg University Hospital will be included into the study during a 24 months study period. Based on activity in 2011, the investigators expect a study population of 600 patients. Door to needle time is the parameter/endpoint strongest associated with prognosis and therefore the most relevant from the patient's point of view. This estimate is well within the planned sample size. However, the sample size is extended in order to allow for analysis of less well-defined endpoints including patient experience.
