Abstract
BACKGROUND: Although many studies have demonstrated racial disparities after major vascular surgery, few have identified the reasons for these disparities, and those that did often lacked clinical granularity. Therefore, our aim was to evaluate differences in initial vascular intervention between black and white patients. METHODS: We identified black and white patients' initial carotid, abdominal aortic aneurysm (AAA), and infrainguinal peripheral artery disease (PAD) interventions in the Vascular Quality Initiative (VQI) registry from 2009 to 2014. We excluded nonblack or nonwhite patients as well as those with Hispanic ethnicity, asymptomatic PAD, or a history of prior ipsilateral interventions. We compared baseline characteristics and disease severity at time of intervention on a national and regional level. RESULTS: We identified 76,372 patients (9% black), including 35,265 carotid (5% black), 17,346 AAA (5% black), and 23,761 PAD interventions (18% black). For all operations, black patients were younger, more likely female, and had more insulin-dependent diabetes, hypertension, congestive heart failure, renal dysfunction, and dialysis dependence. Black patients were less likely to be on a statin before AAA (62% vs 69%; P < .001) or PAD intervention (61% vs 67%; P < .001) and also less likely to be discharged on an antiplatelet and statin regimen after these procedures (AAA, 60% vs 64% [P = .01]; PAD, 64% vs 67% [P < .001]). Black patients presented with more severe disease, including higher proportions of symptomatic carotid disease (36% vs 31%; P < .001), symptomatic or ruptured AAA (27% vs 16%; P < .001), and chronic limb-threatening ischemia (73% vs 62%; P < .001). Black patients more often presented with concurrent iliac artery aneurysms at the time of AAA repair (elective open AAA repair, 46% vs 26% [P < .001]; elective endovascular aneurysm repair, 38% vs 23% [P < .001]). CONCLUSIONS: Black patients present with more advanced disease at the time of initial major vascular operation. Efforts to control risk factors, identify and treat arterial disease in a timely fashion, and optimize medical management among black patients may provide opportunity to improve current disparities.
