Abstract 19569: Racial Differences in Clinical Outcomes and Resource Utilization Associated With Acute Myocardial Infarction Hospitalizations in the United States: A Population-wide Analysis From 2011-2012

Background and objectives: Racial-ethnic disparities in cardiovascular diseases are a major public health problem in the US. There are few recent data on racial differences in clinical outcomes and resource utilization associated with acute myocardial infarction (AMI) hospitalizations. Hypothesis: There are significant racial-ethnic differences in AMI hospitalization outcomes. Methods: We used the 2011-2012 Nationwide/National Inpatient Sample to identify primary AMI hospitalizations. Outcomes of interest included in-hospital mortality, utilization of PCI and thrombolysis, inflation adjusted charges and length of stay. Relevant ICD-9 codes were used. Racial-ethnic differences in outcomes were tested using logistic and linear regression models. Results: 228,302 AMI hospitalizations representing 1.1 million hospitalizations nationwide were included in the study. After adjusting for age, sex, HTN, DM, PCI, thrombolysis, socioeconomic status (SES) and APR-DRG mortality risk, Blacks had significantly lower (OR...
