Medical therapy of diabetic foot infections.

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