Invited commentary

The Wound Ischemia foot Infection (WIfI) classification has gained widespread acceptance in the vascular community as a method of categorizing disease severity in patients with chronic limb-threatening ischemia (CLTI). The original WIfI system is based on a Delphi consensus model, which relies on an iterative process of consensus amongst experts, but is not necessarily data driven. Twelve experts were selected in the formation of the initial WIfI model. The WIfI classification was initially developed in a cohort of CLTI patients not undergoing revascularization, but since then has been extrapolated to predict outcomes of multiple CLTI patient categories, including revascularized and nonrevascularized patients and patients with a variety of comorbidities, including diabetes and chronic kidney disease.
