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. ⋯ 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.

Comparative Study
Is the long-term prognosis of transient ischemic attack or minor ischemic stroke affected by the occurrence of nonfocal symptoms?
In patients with a transient ischemic attack or ischemic stroke, nonfocal neurological symptoms, such as confusion and nonrotatory dizziness, may be associated with a higher risk of vascular events. We assessed the relationship between nonfocal symptoms and the long-term risk of vascular events or death in patients with a transient ischemic attack or minor ischemic stroke. ⋯ This trial was not registered because enrollment began before July 1, 2005.

Comparative Study
Accuracy of emergency medical services-reported last known normal times in patients suspected with acute stroke.
The last known normal (LKN) time is a critical determinant of IV tissue-type plasminogen activator (IV tPA) eligibility; however, the accuracy of emergency medical services (EMS)-reported LKN times is unknown. We determined the congruence between neurologist-determined and EMS-reported LKN times and identified predictors of incongruent LKN times. ⋯ EMS-reported LKN times were largely congruent with neurologist-determined times. Focused EMS training regarding wake-up stroke symptoms may further improve accuracy.
