F-8 | “Racial Disparities in Angioplasty Utilization Without or Without Stenting and Outcomes among Peripheral Arterial Disease Patients: Insights from National Inpatient Sample”

Racial disparities in healthcare persist, driving the need to understand racial differences in angioplasty and hospital outcomes among peripheral arterial disease (PAD) patients for targeted interventions. Utilizing the National Inpatient Sample (NIS) data from 2016 to 2018, 586,180 patients admitted with PAD were analysed, among whom 2060 underwent angioplasty (with or without stenting). The study evaluated racial groups—White, Black, Hispanic, Asian, Native American, and Others—to assess angioplasty utilization and various hospital outcomes, accounting for confounding variables such as age, gender, comorbidities, and socioeconomic factors. Among patients with PAD, White race had no significant impact on angioplasty utilization (aOR= 0.907, P= 0.384), but higher in-hospital all-cause mortality was observed among them (aOR= 1.142, P= 0.033). Conversely, Black race exhibited increased angioplasty rates (aOR= 1.135, P= 0.007) and lower all-cause mortality (aOR= 0.833, P= 0.017), alongside elevated ICU admissions (aOR= 1.147, P=0.49). Hispanic patients demonstrated similar angioplasty rates (aOR= 1.179, P= 0.328) but displayed notable differences in total charges and length of stay, with an average increase of 21584 and 0.302, respectively (P<0.001). Limited disparities were noted among Asian, Native American, and Other racial groups, with varying significance in outcomes such as total charges, ICU admissions, and mortality. Race didn't notably influence angioplasty rates, with the exception of higher odds among Black patients. However, significant racial variations existed in hospital outcomes among PAD patients. White patients faced higher mortality despite similar angioplasty rates, while Black patients had lower mortality and increased angioplasty usage. Hispanic patients showed distinct hospital patterns. Addressing these disparities mandates tailored interventions, ensuring equitable cardiovascular care for all racial groups.
