D-33 | Exploring Racial Disparities in Femoro-Popliteal Bypass for Peripheral Artery Disease: A Population-based Retrospective Study

Persistent racial disparities in post-surgical outcomes prompt an examination of femoro-popliteal bypass surgeries across diverse racial groups. This study meticulously considers demographic and health-related factors, aiming to uncover any existing disparities among these groups in their hospital outcomes following the procedure for peripheral artery disease. Using the NIS dataset from 2016-2018, patients of various racial backgrounds were compared to White individuals as a baseline. Logistic regression models adjusted for confounders to assess odds ratios (aOR) for femoro-popliteal bypass, admission to the ICU, in-hospital mortality, total charges, and length of stay. Those with incomplete demographics, age <18, or did not undergo emoro-popliteal bypass were excluded from the analysis. Our study analysed 586,180 admissions with PAD, out of which, there was 54,650 femoro-popliteal bypass procedure during those admissions. Our analysis showed that Hispanics had the lowest odds for the receiving the procedure (aOR= 0.648, P < 0.001). Blacks exhibited the highest propensity to undergo femoro-popliteal bypass (aOR=1.135, P-value= 0.007). Racial disparities were evident in outcomes post-surgery. Blacks had lower in-hospital mortality (aOR= 0.849, P= 0.034), and higher healthcare costs and length of stay. Hispanics similarly exhibited higher healthcare costs and length of stay. Native American had the lowest total hospital charge and LOS. Notably, disparities were identified among Black and Hispanic groups compared to Whites. This analysis highlights significant racial disparities in femoro-popliteal bypass rates, mortality, healthcare costs, and length of stay among patients with peripheral artery disease. Understanding and addressing these disparities are crucial for equitable healthcare delivery.
