Background Evaluating recombinant tissue plasminogen activator utilization rates is important, as many studies have demonstrated that administration of recombinant tissue plasminogen activator to qualified patients significantly improves prognosis. Aims We investigated recent trends in the utilization and outcomes of administration of intravenous recombinant tissue plasminogen activator in the United States using the National Inpatient Sample between 2001 and 2008. Methods We identified patients with a primary diagnosis of acute ischemic stroke who underwent treatment with intravenous recombinant tissue plasminogen activator and studied utilization rates and clinical outcomes: discharge to long-term facility (morbidity), in-hospital death (mortality), and intracranial hemorrhage. Information on demographics, hospital characteristics, and comorbidities was collected. A multivariate logistic regression analysis was performed to determine independent predictors of morbidity, mortality, and intracranial hemorrhage. Results Intravenous recombinant tissue plasminogen activator utilization increased from 1 center dot 3% in 2001 to 3 center dot 5% in 2008. On multivariate analysis, variables associated with increased morbidity after intravenous recombinant tissue plasminogen activator administration included advanced age (P<0 center dot 001), female gender (P<0 center dot 001), and comorbidities of atrial fibrillation (P<0 center dot 001) and hypertension (P<0 center dot 001). Increased mortality was associated with increased age (P<0 center dot 001) and comorbidities of atrial fibrillation, congestive heart failure, coronary artery disease, and diabetes (P<0 center dot 001 for all comorbidities). Conclusions Intravenous recombinant tissue plasminogen activator utilization rates increased between 2001 and 2008. Advanced age and atrial fibrillation were significantly associated with increased morbidity and mortality among patients treated with intravenous recombinant tissue plasminogen activator.
