Background and Purpose-Frequencies of treatment with r-tPA (recombinant tissue-type plasminogen activator) are increasing over the past 15 years. However, published data on the influence of various demographic and clinical factors on r-tPA treatment as well as estimates of future trajectories are limited. We evaluated time trends and future trajectories of r-tPA treatment in patients with acute stroke and the influence of various factors on r-tPA treatment by analyzing data of 103 970 patients enrolled in the Austrian Stroke Unit Registry from 2006 to 2018, of which 18 953 were treated with r-tPA. Methods-Time trends of r-tPA-treatment were investigated in predefined subgroups (minor/major stroke, age, anterior/posterior circulation stroke); limited exponential time series models were calculated to estimate future trends of r-tPA-treatment. Logistic regression models were calculated to estimate the influence of clinical variables on r-tPA-treatment. Results-Overall, r-tPA treatment frequencies increased from 9.9% in 2006 to 21.8% in 2018. We observed a particular increase in patients >80 years, patients presenting with a National Institutes of Health Stroke Scale Score of 2 to 3, patients with posterior circulation stroke, patients with wake-up stroke, and patients without atrial fibrillation. Forecast of overall r-tPA frequencies predicted a further but flattened increase up to 24% by 2025. Logistic regression of time-dependent associations of clinical variables with r-tPA-treatment revealed increasing odds of r-tPA-treatment in patients with a posterior circulation stroke and decreasing odds of r-tPA-treatment in patients with atrial fibrillation. Conclusions-We observed a positive development of r-tPA-treatment frequencies mirroring increasing confidence with intravenous thrombolysis in clinical practice; however, decreasing odds of r-tPA-treatment over time in patients with atrial fibrillation deserve particular attention.
