Abstract W P310: Contemporary Trends In The Ischemic Stroke “Weekend Effect” On IV Thrombolytic Use, In-hospital Mortality, Discharge Disposition, Hospital Charges, And Length Of Stay - A National Perspective

Background: We sought to check current stutus of weekend effect (differences in acute ischemic stroke (AIS) outcomes between patients admitted at the weekend versus weekday) which is the basis of many change in health policy to deal with disparities. Objective: To evaluate the influence of admission on a perticular day of the week (DOW) on outcomes in AIS pts. Methods: We reviewed the HCUP9s Nationwide Inpatient Sample (NIS) database from 2008 - 11 for all emergency room (ER) admissions for AIS using ICD 9-CM code. NIS represents 20% of all US hospital. Pts aged Results: A total 390,401 (weighted: 1,933,243) ER admissions were studied, of which 99,968 (weighted: 494,863) were admitted on weekends. The average age of the cohort was 71 years, 53.4 % females, and 60.8% were whites. In univariate analysis, admission on weekend was associated with higher mortality (7.28% vs. 7.13%, p Conclusion: Admission on a weekend is a predictor of higher utilization of IVT and discharge to a long-term facility , but there was no difference in in-hospital mortality or cost of care.
