The Society for Vascular Surgery's objective performance goals for lower extremity revascularization are not generalizable to many open surgical bypass patients encountered in contemporary surgical practice.

OBJECTIVE In 2009, the Society for Vascular Surgery (SVS) established objective performance goals (OPG) for lower extremity bypass (LEB) in patients with critical limb ischemia (CLI) based on pooled data from previously performed prospective studies in an effort to provide a benchmark and historical control for future trials. However, patients with a prosthetic conduit and end-stage renal disease were excluded from this cohort. In contemporary practice, many patients do not meet the criteria for SVS OPG inclusion, making generalization of the SVS OPG difficult. The goal of this study was to establish safety and efficacy measures for patients who were excluded from the original SVS OPG analysis. METHODS All patients who underwent LEB for CLI in the Vascular Study Group of New England (VSGNE) from 2003 to 2013 were identified. Patients were stratified into OPG-eligible and non-OPG-eligible cohorts. Outcomes included 30-day major adverse limb events, 30-day major adverse cardiovascular events, 1-year survival, and 1-year freedom from amputation. The SVS OPG methodology was used to create new performance goals for the non-OPG-eligible patients. RESULTS We identified 3609 patients: 2360 OPG (65%) vs 1249 non-OPG (35%), and overall results were stratified as a function of OPG status. The 30-day major adverse limb event rate was 5.0% (5.5% non-OPG vs 4.4% OPG; P = .34), and the 30-day major adverse cardiovascular event rate was 7.3% (9.2% non-OPG vs 6.2% OPG; P = .001). At 1 year, survival was 84% (75.9% non-OPG vs 88.3% OPG; P < .001), and freedom from amputation was 86.9% (80.9% non-OPG vs 90.1% OPG; P < .001). CONCLUSIONS The SVS OPG were attainable in New England for the population of patients who would have met SVS OPG study cohort inclusion criteria. However, 35% of the patients who underwent LEB for CLI in the last 10 years fell outside of these criteria by having end-stage renal disease or requiring a prosthetic conduit. We therefore suggest new benchmarks for these high-risk populations.
