Abstract 115: Current Status of Acute Stroke Management in Korea: A Nationwide Report Based on 19,608 Patients Treated in 216 Hospitals

Abstract

Introduction: There have been few reports on status of acute stroke management at a national level worldwide, and none in Korea. This study is aimed to describe the current status and disparities of acute stroke management in Korea. Methods: Data from 5th (2013) and 6th (2014) national surveys for assessing quality of acute stroke care were used. Patients with principal diagnosis codes indicating subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH), ischemic stroke (IS), who were admitted via emergency rooms within 7 days of onset at hospitals treating 10 or more stroke cases during the each 3-month survey period were selected. Results: A total of 19,608 stroke cases (age, 67.7±13.5years; female, 45%; IS, 76%; ICH, 15%; SAH, 9%) treated in 216 hospitals were analyzed. Thirty-one percent of hospitals had stroke units and 41% of stroke cases were treated at hospitals without stroke units. In IS, IV thrombolysis (IVT) and endovascular treatment (EVT) rates were 10.7% and 3.6%, respectively. Thirty-nine percent of IVT and fifty-two percent of EVT cases were performed in hospitals with annual volume of <25 IVT and <15 EVT. Centralization of EVT showed disparities by region (Figure). Carotid endarterectomy, carotid artery stenting, decompressive, bypass surgery was conducted in 0.2%, 1.4%, 1.0%, 0.2% of IS cases; decompressive surgery was done in 28.1% of ICH cases; surgical clipping, endovascular coiling was done in 17.2%, 14.3% of SAH cases, respectively. There were noticeable regional disparities in various interventions, use of ambulance, arrival time and provision of stroke unit service. Conclusions: This study is the first report on the status of acute stroke care in Korea on a national level. Large number of recanalization therapies were performed in low-volume-hospitals. Expansion of stroke unit service, stroke center certification or accreditation, and connections between stroke centers and EMS are highly recommended.
