The Society for Vascular Surgery Wound, Ischemia, and foot Infection (WIfI) classification system correlates with cost of care for diabetic foot ulcers treated in a multidisciplinary setting

Increasing WIfI stage is associated with a prolonged wound healing time, a higher number of surgical procedures, and an increased cost of care. While limb salvage outcomes are excellent, the overall cost of DFU care from presentation to healing is substantial, especially for patients with advanced (WIfI stage 3/4) disease treated in a multidisciplinary setting.
