Introduction: Low socioeconomic status (SES), distance lived from hospital, and insurance status are well documented in the literature to increase the risk of post-operative morbidity and mortality for some disease processes however there is a paucity of data regarding how this association impacts patients with peripheral artery disease (PAD). This study aimed to evaluate if SES, distance lived from hospital, and insurance status increased the risk of developing major graft failure in patients undergoing revascularization procedures for symptomatic PAD in a prospective, observation study. Methods: In this prospective, observational study, all patients undergoing lower extremity revascularization (endovascular or open) were included from December 2020 to February 2022. Demographic factors, insurance status, operative details, and median income and distance from hospital were documented through chart review. Complications were defined as thrombosis/occlusion of the revascularized vessel or bypass graft or infection of the distal wound or surgical incision wound. Univariate and multivariate analysis were performed comparing patients that developed complications and those that did not. This project was undertaken at the Massachusetts General Hospital and was governed by the Institutional Review Board (IRB: 2020P000263) all patients agreed to participation via informed written consent prior to enrollment in the study. Results: A total of 108 patients were enrolled in the study of which 94 underwent successful revascularization procedures. Of those 94 patients, 38 (40.4%) underwent open bypass, 39 (41.5%) underwent endovascular revascularization, and 17 (18.1%) underwent a hybrid approach. There were no significant differences in post-operative outcomes between operative approaches. Twenty-five patients (28.7%) experienced major revascularization complications as defined as re-occlusion of the treated vessel/thrombosis of the bypass graft (n = 13) or development of post-operative infection (n = 12). There was no significant difference in median income ($75,295 vs $87,757, p = NS), distance lived from hospital, (27.4 miles vs. 29.7 miles, p = NS), or type of insurance (private 24% vs 26%, government 76% vs 73%, p = NS between patients that experienced complications versus those that did not have complications. These findings suggest the risk of major graft failure is independent of a patient's socioeconomic status, distance lived from hospital, or insurance type in patients undergoing revascularization procedures for PAD. Conclusion: While socioeconomic factors impact access to and have a known association with negative outcomes, complications in patients with PAD appear to be independent of these factors. To mitigate the negative outcomes in patients with peripheral artery disease, a focus should be on patient risk factors and modifiable medical factors that contribute to adverse outcomes.
