Factors associated with use of emergency medical services in patients with acute stroke.
PURPOSES: The aim of this study was to investigate the factors associated with use of emergency medical services (EMS) in patients with acute stroke.
METHODS: Prospective data on consecutive patients with acute stroke who presented to the emergency department of a university medical center from January 1, 2010, to July 31, 2011, were analyzed. Patients were excluded if they had an unknown residence, had onset of stroke at a nursing home or hospital, or were transferred from another hospital. Variables for all patients with stroke and ischemic stroke who did and did not use EMS were compared.
RESULTS: In total, 1344 patients (60% male; mean age, 68.7 years) were included. Use of EMS (n = 409; 30.4%) was significantly associated with a higher level of education (≧6 years vs <6 years; odds ratio [OR], 1.69; 95% confidence interval [CI], 1.25-2.29), a higher National Institutes of Health Stroke Scale score (OR, 1.08; 95% CI, 1.05-1.11), altered consciousness (OR, 1.88; 95% CI, 1.25-2.84), and atrial fibrillation (OR, 2.43; 95% CI, 1.71-3.44) after adjustment. For patients with ischemic stroke, use of EMS was significantly higher in cases of cardioembolism (OR, 3.04; 95% CI, 1.40-6.60) and large artery atherothrombosis (OR, 2.10; 95% CI, 1.22-3.62) than lacunar infarction.
CONCLUSION: Patients with stroke who have altered consciousness, a higher level of education, a higher National Institutes of Health Stroke Scale score, atrial fibrillation, and cardioembolic stroke were more likely to use EMS.
