Evaluation of the WIfI classification system in older patients with diabetes

In January 2014, the Society for Vascular Surgery published its new threatened limb classification system based on Wound extent, degree of Ischemia and foot Infection (WIfI). This classification represents a summary of multiple previously published classifications focused on diabetic foot ulcers and pure ischaemia or infection models. Despite the new system, patient-centred functional outcomes — such as wound healing or maintenance of ambulation — remain incompletely evaluated in this population. By and large, doctors who are using the WIfI classification will report mainly on the risk of amputation and benefit of revascularisation at 1 year, but will not report about patient survival or the probability of ulcers healing.
