Emergency Department Time Targets for Interhospital Transfer of Patients with Acute Ischemic Stroke

Abstract

Background and objectives: Although the intravenous tissue plasminogen activator (rt-PA) has been shown to be effective in the treatment of acute ischemic stroke (AIS), only a small proportion of stroke patients receive this drug. The low administration rate is mainly due to the delayed presentation of patients to the emergency department (ED) or the lack of a stroke team/unit in most of the hospitals. Thus, the aim of this study is to analyze ED time targets and the rate of rt-PA intravenous administration after the initial admission of patients with AIS in an ED from a traditional healthcare center (without a neurologist or stroke team/unit). Methods: To analyze which factors influence the administration of rt-PA, we split the general sample (n = 202) into two groups: group No rt-PA (n = 137) and group rt-PA (n = 65). This is based on the performing or no intravenous thrombolysis. Results: Analyzing ED time targets for all samples, we found that the median onset-to-ED door time was 180 min (IQR, 120–217.5 min), door-to-physician time was 4 min (IQR, 3–7 min), door-to-CT time was 52 min (IQR, 48–55 min), and door-in-door-out time was 61 min (IQR, 59–65 min). ED time targets such as door-to-physician time (p = 0.245), door-to-CT time (p = 0.219), door-in-door-out time (p = 0.24), NIHSS at admission to the Neurology department (p = 0.405), or NIHSS after 24 h (p = 0.9) did not have a statistically significant effect on the administration or no rt-PA treatment in patients included in our study. Only the highest door-to-CT time was statistically significantly correlated with the death outcome. Conclusion: In our study, the iv rt-PA administration rate was 32.18%. A statistically significant correlation between the highest door-to-CT time and death outcome was found.
