Abstract T MP24: Are There Disparities in Thrombolytic Treatment and Mortality in Acute Ischemic Stroke in the Hispanic Population Living in Border States versus Non-Border States?
Background: Recent studies have found an underutilization of hospital in-patient care for coronary artery disease in Hispanics living in Border States.
Objective: To identify acute treatment disparities in acute ischemic stroke Hispanic patients and determine the effect of such disparity on patient outcomes.
Methods: We identified Hispanic and non-Hispanic acute ischemic stroke patients from the Nationwide Inpatient Sample-2011 data files. We determined the rate of utilization of thrombolytics and outcomes according to patient’s demographic and clinical characteristics and whether or not they lived in a Border state (defined as California, Arizona, New Mexico and Texas).
Results: A total of 34,904 Hispanic patients were admitted with ischemic stroke; of those 21,130 were admitted in Border states and 13,774 in non-Border states. Patient demographics, risk factors, complications and discharge disposition are included in the Tables below. There was a significantly lower rate of thrombolytic use in Hispanic patients (1013 (4.8%) and non-Hispanics (5326 (5.7%, p=0.05). After adjusting for age, gender, and other confounding risk factors, Hispanics were 30% more likely to suffer in-hospital mortality versus there non-Hispanic counter-parts in Border states [OR 1.3 (1.1-1.6) p=0.009], which was not apparent in the non-Border states [OR 1.0 (0.8-1.2) p=0.9].
Conclusions: There was an underutilization of thrombolytics and higher mortality in the Hispanic population admitted in Border States but not in non-Border States. Further studies are warranted to better understand the associated factors.
