Abstract
To compare the total initial treatment costs for open surgery, endovascular revascularization, and primary major amputation within a single-payer healthcare system. A multicenter, retrospective analysis was undertaken to evaluate 1138 patients with symptomatic peripheral artery disease (PAD) who underwent 1017 endovascular procedures, 86 open surgeries, and 35 major amputations between 2013 and 2016. A cost-mix analysis was performed on individual patient data generated for selected diagnosis-related groups. Mean costs are presented with the 95% confidence interval (CI). There was no intergroup difference in demographics or private health insurance status. However, the amputation group had a higher proportion of emergency procedures (68.6% vs 13.3% vs 27.9%, p<0.001) and critical limb ischemia (88.6% vs 35.9% vs 37.2%, p<0.001) compared with the endovascular therapy and open surgery groups, respectively. The endovascular revascularization group spent less time in hospital and used fewer intensive care unit (ICU) resources compared with the open surgery and major amputation groups (hospital length of stay: 3.4 vs 10.0 vs 20.2 days, p<0.01; ICU: 2.4 vs 22.6 vs 54.6 hours, p<0.01), respectively. While mean prosthetic and device co...Continue Reading
