Abstract T MP62: Persistent Racial Disparities in Outcomes for Middle-aged People With Intracerebral Hemorrhage in the US Stroke ‘Buckle’
Background: Intracerebral hemorrhage (ICH) has no cure and is associated with substantial morbidity and mortality. While the burden of ICH on Black patients (vs. Non-Hispanic White counterparts) has long been recognized, recent comparative trends in the racial characteristics of ICH among people < 65 years of age within the stroke-prone, Southeastern region (‘buckle of the stroke belt’) of the United States, have not been fully examined.
Methods: Utilizing the South Carolina hospital discharge database, patients (age 25-64 years) discharged with a primary diagnosis of ICH (ICD9 431) from 2001 to 2012 were identified. Black to White disparity rate ratios for stroke hospitalizations and in-hospital mortality were calculated based on rates per 100,000 population by discharge year. Clinical characteristics were compared by multivariate logistic regression adjusting for age and gender.
Results: There were 4,285 (Blacks = 2,557 and Whites = 1,728) ICH hospitalizations from 2001 to 2012 in patients < 65 years of age. Black patients had significantly worse clinical characteristics as compared to Whites (table); and experienced almost 4 times the rate of ICH hospital admissions and 3 times the rate of in-hospital mortality compared to White patients (figure). These racial disparity differences did not significantly vary over the time period.
Conclusions: Over the last 12 years, rates of hospital-based ICH outcomes remained persistently and considerably poorer among middle-aged Black vs. White patients within the US Stroke Buckle. Intensified efforts aimed at mitigating the personal and societal burden of this lingering racial disparity are warranted.
