Consensus document on treatment of infections in diabetic foot.

Diabetic foot infection, particularly if it is associated to ischaemia,is the most common cause of lower limb amputation, in the general population, of hospital admissions, and a decrease in the quality of life in diabetics. Of all diabetics, 15% of them are going to suffer from a foot infection during their life, with an annual incidence of 1-4%, preceded by a foot ulcer in more than 80% of cases. They are complex infections and the prognosis is influenced by many factors, depending on the ulcer (location, extension, whether chronic or not, previous amputation, ischaemia grade), and the patient (age, renal impairment, time of onset of diabetes, associated comorbidity). All these must be taken into account when establishing its treatment. The infections must be classified according to their severity (mild, moderate-mild, moderatesevere, and severe). Their treatment is complex and must be multidisciplinary and must include debridement, discharge, adequate antibiotic therapy, revascularisation, and treatment of the ulcer. In this consensus document, produced in collaboration with the Spanish Angiology and Vascular Surgery Society (SEACV), the Spanish Society of Internal Medicine (SEMI), the Spanish Chemotherapy Society (SEQ), the Spanish Surgeons Association (AEC), the Spanish Society of Urgent Medicine and Emergencies (INFURG-SEMES) and the Spanish Society of Intensive and Critical Medicine and Coronary Care (SEMICYUC), the guidelines are developed based on the best available evidence on diabetic foot infections, aimed at achieving greater clinical efficacy.
