BACKGROUND AND PURPOSE: The benefits of intravenous tissue-type plasminogen activator in acute ischemic stroke are time dependent, and several strategies have been reported to be associated with more rapid door-to-needle (DTN) times. However, the extent to which hospitals are using these strategies and their association with DTN times have not been well studied. METHODS: We surveyed 304 Get With The Guidelines-Stroke hospitals joining TARGET: Stroke regarding their baseline use of strategies to reduce DTN times in the January 2008 to December 2009 time frame before the initiation of TARGET: Stroke and determined the association between hospital strategies and DTN times. RESULTS: Among 5460 patients receiving tissue-type plasminogen activator within 3 hours of symptom onset in surveyed hospitals, the median DTN time was 72 minutes (interquartile range, 55-94). Reported use of the different strategies varied considerably. Of 11 hospital strategies analyzed individually by multivariable analysis, 3 strategies were independently associated with shorter DTN times. These included rapid triage/stroke team notification (209/304 69% hospitals, 8.1-minute reduction in DTN time), single-call activation system (190/304 63% hospitals, 4.3 minutes), and tissue-type plasminogen activator stored in the emergency department (189/304 62% hospitals, 3.5 minutes). When analyzed incrementally, hospitals that used a greater number of strategies had shorter DTN times with 1.3 minutes (adjusted mean difference) saved for each strategy implemented (14 minutes if all strategies were used). CONCLUSIONS: Although the majority of participating hospitals reported using some strategy to reduce delays in tissue-type plasminogen activator administration for acute ischemic stroke, the strategies applied vary considerably and those most strongly associated with shorter DTN times were applied relatively less frequently.
