Abstract

Objective Early management of patients with acute ischemic stroke is crucial regardless of the time of presentation. The aim of the study was to evaluate the effect of off-hours management of patients with ischemic stroke that underwent thrombolytic therapy in the emergency department. Methods This is a single-center retrospective study included ischemic stroke patients who received thrombolysis in the emergency department from January 2009 to April 2017. Patients who presented between 08:00 and 17:00 Monday to Friday were in the 'work-hour group (group 1)' versus others who were considered 'off-hours (group 2)'. Primary endpoint was 3-month mortality. Secondary endpoints included the National Institutes of Health Stroke Scale and dramatic recovery rate at 24 h, intracranial hemorrhage, systemic hemorrhage and modified Rankin Scale at the 3 months. Symptom-to-needle time, door-to-computed tomography time, and door-to-needle time were also compared between groups. Results A total of 399 ischemic stroke patients were included in the analysis, 137 (34%) during work-hours and 262 (66%) during off-hours. The mortality rate was not different at 3 months between groups: 24 (17.5%) in the work-hours group versus 38 (14.5%) in the off-hours group [odds ratio 1.25; 95% confidence interval (CI), 0. 72-2.19]. There were no differences between groups on secondary endpoints. The mean time of symptom-to-needle was significantly higher during off-hours (mean difference: 18.4 min; 95% CI, 7.81-29.0). Conclusions In this study, there were no significant differences in mortality and functional outcomes at 3 months between patients who underwent off-hour or work-hour thrombolysis in the emergency department.
