Abstract TP196: Characteristics And Outcomes Of Acute Stroke Among Black Adults By Sex, Paul Coverdell National Acute Stroke Program 2012-2018

Introduction: The nation’s highest rates in stroke deaths are among Blacks. After years of decline, the death rate began to stall around the beginning of this decade. This study will describe differences in stroke characteristics and outcomes by sex within this racial group. Method: The study is limited to patients identified as black and admitted with a clinical diagnosis of intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH), or ischemic stroke (IS) in the Paul Coverdell National Acute Stroke Program (PCNASP) from 2012-2018. In total, there were 105,676 admissions from 521 participating hospitals. We compared sociodemographic and clinical characteristics by sex within this racial group. Results: Among stroke admissions for black patients, 14,785 (14.0%) were ICH, 4,520 (4.3%) were SAH, and 86,371 (81.7%) were IS. Black women suffered a greater proportion of ICH (5.3% vs 3.2%, p<.0001) and a smaller proportion of SAH (13.0% vs 15.0%, p<.0001) than black men. Black women who suffered an IS were more likely to arrive by EMS than black men (49.7 vs. 47.7%). Black men who suffered an ICH or IS were more likely than black women to be transferred from another hospital (ICH: 34.1% vs 32.4%; IS: 11.9% vs 10.7%). Black men were more likely than black women to be discharged home after IS (50.9% vs 48.1%). Across stoke types, a greater proportion of black men were able to ambulate independently at discharge. Conclusion: In this sample, IS was the most common diagnosis among both men and women (81.8% vs 81.7%) and well-known cardiovascular disease risk factors were identified. Although a number of differences between men and women were found to be statistically significant, the clinical impact is unknown. Clinicians and public health practitioners may need to develop targeted interventions or services for black women to reduce disparities in stroke and risk factors within this racial group.
