F-11 | Disparities in Peripheral Artery Disease Inpatient Endovascular Interventions

A recent Scientific Statement published in the Journal of American College of Cardiology in December 2023 highlighted racial and sex-specific disparities in treatment for peripheral artery disease (PAD) using data from up to 20 years ago. We sought to evaluate disparities in endovascular PAD treatment with more recent data from 2016 to 2020. Bayesian machine learning-augmented propensity score translational (BAM-PS) statistics with multivariable regression was conducted for the largest US all-payor inpatient dataset, the National Inpatient Sample (NIS), from 2016 to 2020. Of 148,755,036 adult hospitalizations from 2016-2020, there were 17,173,000 (11.54%) with PAD, of whom 680,025 (3.96%) underwent inpatient endovascular revascularization (ER). ER prevalence from 2016-2020 increased steadily (0.46% to 0.49%) (p 0.05 for all). This nationally representative analysis suggests that significant racial and sex-specific disparities persist in ER for PAD. Clinicians must actively strive to alleviate these disparities using a multidisciplinary approach.
