Background Some prior studies have shown that racial disparities exist in intravenous tissue plasminogen activator (IV tPA) utilization for acute ischemic stroke. We sought to determine whether race was associated with tPA treatment for stroke in a predominantly black urban population. Methods Systematic chart abstraction was performed on consecutive hospitalized ischemic stroke patients from all seven acute care hospitals in the District of Columbia from Feb 1, 2008 to Jan 31, 2009. Results Of 1044 ischemic stroke patients, 74%% were black, 19% non-Hispanic white, 5% received IV tPA. Blacks were one third less likely than whites to receive IV tPA (3% vs. 10%, p<0.001). However, blacks were also less likely than whites to present within 3 hours of symptom onset (13% vs. 21%, p=0.004) and also less likely to be tPA-eligible (5% vs. 13%, p<0.001). Of those who presented within 3 hours, blacks were almost half as likely to be treated with IV tPA than whites (27% vs. 46%, p=0.023). The treatment rate for tPA-eligible patients was similar for blacks and whites (70% vs. 76%, p=0.62). Conclusions In this predominantly black urban population hospitalized for acute ischemic stroke, blacks were significantly less likely to be treated with IV tPA due to contraindications to treatment, delayed presentation, and stroke severity. Effective interventions designed to increase treatment in this population need to focus on culturally relevant education programs designed to address barriers specific to this population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
