Diabetic foot infections are a common and often serious problem, accounting for more hospital bed days than any other complication of diabetes. Despite advances in antibiotic drug therapy and surgical management, these infections continue to be a major risk factor for amputations of the lower extremity. Although a variety of wound size and depth classification systems have been adapted for use in codifying diabetic foot ulcerations, none are specific to infection. In 2003, the International Working Group on the Diabetic Foot developed guidelines for managing diabetic foot infections, including the first severity scale specific to these infections. The following year, the Infectious Diseases Society of America published their diabetic foot infection guidelines. Herein, we review some of the critical points from the Executive Summary of the Infectious Diseases Society of America document and provide a commentary following each issue to update the reader on any pertinent changes that have occurred since publication of the original document in 2004. The importance of a multidisciplinary limb salvage team, apropos of this special issue jointly published by the American Podiatric Medical Association and the Society for Vascular Surgery, cannot be overstated.
