A 67-item Likert-scale survey was administered by telephone to stroke personnel at 252 U.S. hospitals participating in the "Get With The Guidelines-Stroke" quality improvement program. Factor analysis was used to refine the instrument to a four-factor 29-item instrument that can be used by hospitals to assess their readiness to administer intravenous tissue plasminogen activator within 60 minutes of patient hospital arrival.Cerebral InfarctionEarly Medical InterventionEfficiency, OrganizationalGuideline AdherenceHumansInfusions, IntravenousPatient AdmissionPatient Care TeamQuality ImprovementThrombolytic TherapyTime and Motion StudiesTissue Plasminogen ActivatorWorkflowJournal article1945-2810
