To quantify the impact of an integrated diabetic foot surgical service on outcomes and changes in surgical volume and focus.
We abstracted registry data from 48 consecutive months at a single institution, evaluating all patients with diabetic foot complications requiring surgery or vascular intervention and compared outcomes in the 24 months before and after integrating podiatric surgery with vascular surgical limb-salvage service.
The service performed 2923 operations; 790 (27.0%) were related to treatment of diabetic foot complications in 374 patients. Of these, 502 were classified as non-vascular diabetic foot surgery and 288 were vascular interventions. Urgent surgery was significantly reduced after team implementation (77.7% vs. 48.5% p <0.0001, OR = 3.7, 95% CI: 2.4 – 5.5). The high/low amputation ratio decreased from 0.35 to 0.27 due to an increase in low-level (midfoot) amputations (8.2% vs. 26.1%, p <0.0001, OR = 4.0, CI: 2.0 to 83.3) A 45.7% reduction in BKAs was realized with a stable above knee/below knee amputation (AKA/BKA) ratio (0.73 to 0.81). One-third of patients required vascular intervention. Vascular reconstructions increased 44.1% following institution of the team. Initial revascularization was endovascular in 70.6% of patients. Repeat endovascular intervention or conversion to open bypass was required in 37.1% of these patients, almost double the reintervention rate of those receiving open bypass first (18.9%).
