Management of diabetic foot infections in an era of increasing microbial resistance.

Diabetic foot infections cause substantial morbidity, incur significant costs, and may lead to amputation. Resistant organisms, particularly methicillin-resistant Staphylococcus aureus (MRSA) and multidrug-resistant gram-negative organisms, are becoming more prevalent. Optimal management of diabetic foot infections is multimodal, and includes not only antimicrobial therapy but also biomechanical support and offloading, local wound care, glycemic control, assessment and treatment of underlying vascular disease, and surgical therapy when warranted.
