guidelines recommend a door-to-needle(DTN)time of 60 minutes.Yet prior studies suggested fewer than 30%of intravenous tPA treated acute ischemic stroke patients in the United States were meeting this goal.To address this shortfall,Target:Stroke,a national initiative organized by the AHA/ASA,was launched in January 2010 to increase the proportion of stroke patients with DTN times 60 minutes(initial goal of 50%).,Improving Door-to-Needle Times in Acute Ischemic Stroke:Principal Results from the Target:Stroke Initiative.ISC 2014,LB12,相关研究,Improving Door-to-Needle Times in Acute Ischemic

Guidelines-Stroke项目中DNT的平均时间为72分钟，因此，缩短14分钟将使大多数患者达到60分钟的治疗目标，从而挽救数以千计患者的残疾命运。,+,1种策略,+,10种策略,1.3分钟,14分钟,P=0.011,相关研究,Xian Y,et al.Strategies Used by Hospitals to Improve Speed of Tissue-Type

assessments,inappropriate patient selection,dosing errors,and greater likelihood of complications,our findings suggest that more rapid reperfusion therapy in acute ischemic stroke is not only feasible,but can be achieved with actual reductions in complications and improved outcomes.These findings further reinforce the importance and substantial clinical benefits of more rapid administration of intravenous tPA.,Fonarow GC et
