Abstract 20395: Racial/Ethnic and Gender Disparities in Use of Drug-Eluting vs. Bare Metal Stents in ST-Elevation Myocardial Infarction Patients, 2006-2012

Background: Recent evidence continues to show the benefit of drug-eluting stents (DES) over bare metal stents (BMS) in patient outcomes following ST-elevation myocardial infarction (STEMI), although the use of DES may be contraindicated in patients with specific comorbidities. In this study, we investigated racial/ethnic and gender disparities in the use of DES, after controlling for the effects of age, insurance status, secular trends, and comorbidities. Methods: The study population included all STEMI patients (n=60,218) who received PCI and at least one stent in any Florida acute-care hospital during 2006-2012. Hospital discharge data were analyzed. Procedure codes identified DES (ICD-9-CM 36.07) and BMS (ICD-9-CM 36.06). We used logistic regression to model the odds of receiving a DES. Potential predictors included in the model were patient age, racial/ethnic-gender group (referent=White men), year, payer (referent=commercial), diabetes, atrial fibrillation (AFIB), chronic kidney disease (CKD), and en...
