Abstract WP341: Difference in Acute Ischemic Post Thrombolytic Stroke Outcomes in Pre Comprehensive and Post Comprehensive Status: Single Center Experience

Abstract

Background: In last decade there is a significant change in stroke care especialy with newer data for ischemic stroke treatment there is a movement to obtain comprehensive stroke center certification (CSCC) to provide enhanced complex care for stroke. This study aims to assess the single center quality matrix assessment pre and post CSC status Methods: We reviewed single center cohort of IV tPA (tissue plasminogen activator) in-between year 2010 to 2014 at sparrow health system in mid Michigan region. This cohort was dichotomized in pre CSCC and post CSCC era. Stroke quality matrics data was collected for these patients. Severity of stroke was categorized in mild-moderate vs moderate-severe based on NIH stroke scale (NIHSS) scale. Primary out come for this study was any complication, which is composite end point of in-hospital mortality, and hemorrhage and secondary outcome was hospital stay. Chi square, student’s t test and wilcoxon sum rank test was used to compare both groups. Multivariable regression models were utilized to calculate odd ratios after adjusting with stroke severity. Results: Cohort of IV tPA was identified in-between year 2010 to 2014 (332 hospitalizations off which 241 were pre CSCC and 91 were Post CSCC ). In- hospital complication was lower after receiving CSCC (9.89% vs. 21.99%; p:0.011). In multivariable regression analysis the trend for in hospital complication persisted [Adjusted Odds ratio (OR):0.43–95%confidence-Interval(CI):0.20-0.93–p:0.032] but there was no significant difference in hospital stay (Median days 5 vs. 5; P:673) Conclusion: There is a clear and persistent trend of low in-hospital complication rates after acquiring CSCC quality matrics.
