Abstract WP198: Trends of Racial Disparity in Stroke Hospitalization Rate and Hospital Charges in the Buckle of Stroke Belt In the Past Decade (2001-2010)
Background: Racial disparities in stroke patients have been well documented but trends of disparity in the past decade are not clear. This study aims to determine whether racial disparities changed in South Carolina between African Americans (AAs) and Caucasian Americans (CAs) in stroke hospitalization rates and hospital charges from 2001 to 2010.
Methods: From the state uniform billing hospital discharge database, patients discharged with a primary diagnosis of stroke from 2001 to 2010 were identified. Age, race, stroke subtype, group-specific stroke hospitalization rates, and hospital charges were compared over the 10 years period.
Results: There were 89,357 stroke hospitalizations from 2001 to 2010. Stroke hospitalization rates decreased in all age-race groups but less significant in younger groups. Rates were persistently higher for AAs in all age groups, but the racial disparity was more pronounced in the younger group across all stroke subtypes. The highest disparity exists in the 35-45 year old group with intracerebral hemorrhage. Ten year hospital charges totaled $3.0 billion; 39.0% ($1171.0 million) of this total were attributable to racial disparities, 88.6% ($1037.9 million) is from the < 65 years old group.
Conclusions: Racial disparities in stroke hospitalization rates are more severe in the younger age groups and result in significant economic consequences for the state.
