Association of Geographical Factors With Administration of Tissue Plasminogen Activator for Acute Ischemic Stroke

J Am Heart Assoc.: 9/17/13

 

Background Intravenous tissue plasminogen activator (tPA) is an effective treatment for acute ischemic stroke if administered within a few hours of stroke onset. Because of this time restriction, tPA administration remains infrequent. Ambulance use is an effective strategy for increasing tPA administration but may be influenced by geographical factors. The objectives of this study are to investigate the relationship between tPA administration and ambulance use and to examine how patient travel distance and population density affect tPA utilization. read more
