We used data from the Clinical Research Center for Stroke-5 registry between January 2011 and March 2014. Among patients treated with tissue-type plasminogen activator (tPA), the use of the drip-and-ship paradigm was evaluated, and time delays and functional outcomes at 3 months were compared between patients treated with the paradigm and those treated directly at visits.
Among 1843 patients who met the eligibility criteria, 244 patients (13.2%) were treated with the drip-and-ship paradigm. Subsequent endovascular recanalization therapy was used in 509 patients (27.6%). The median time from symptom onset to groin puncture was greater in patients treated with the paradigm than in those treated directly at visits (305 versus 200 minutes, P < .001). In multivariate analysis, the risks of unfavorable functional outcomes and symptomatic intracranial hemorrhage were higher inpatients treated with the paradigm than in those directly treated at visits (odds ratio [OR] 2.15; 95% confidence interval [CI], 1.50-3.08; P < .001 and OR 1.78; 95% CI, 1.02-3.12; P = .041, respectively).
In Korea, the drip-and-ship paradigm was used in less than 15% of all patients treated with tPA. The use of the paradigm might cause an increase in the onset-to-groin puncture time. Additionally, clinical outcomes might be worse in patients treated with the paradigm than in those treated directly at visits.
