Abstract W MP99: Seven-Day Mortality After Ischemic Stroke: International Comparison Among Industrialized Nations

Introduction: Stroke is the 2nd leading cause of death worldwide, yet best practices for acute stroke care are lacking even among premier hospitals in industrialized countries. We compared 7-day mortality after ischemic stroke between academic medical centers in the Netherlands (NL), United Kingdom (UK), and United States (US). Methods: This was an observational study using in-hospital administrative data from select academic medical centers in the NL (n=8), UK (n=10), and US (n=11) from 2005-12. Chi-square was used to compare 7-day in-hospital mortality between countries and across years, and to explore the effect of weekend admission. Multiple logistic regression was conducted to further examine factors associated with mortality, including sex, age, weekend admission, year, and country. Results: From 2005-12, 51,409 patients were discharged with ischemic stroke from hospitals in the NL (n=6331), UK (n=25574), and US (n=19204). Mortality was significantly higher in the UK (8.1%) compared to the NL (6.4%)...
