How Would You Manage This Diabetic Patient With a Foot Infection? Grand Rounds Discussion From Beth Israel Deaconess...

Foot infections are the most common cause of hospitalization in patients with diabetes. They may be superficial, involving only the skin, or deep, involving the soft tissues or bone. Superficial infections are generally caused by aerobic gram-positive cocci, whereas deep infections, including osteomyelitis, tend to be polymicrobial in origin. Clinical manifestations of skin and soft tissue infections include local evidence of inflammation, but peripheral neuropathy and peripheral artery disease may mask these findings. Management is determined by the extent of infection and often includes oral or parenteral antibiotic therapy in combination with surgical debridement. In 2023, the International Working Group on the Diabetic Foot and the Infectious Diseases Society of America updated their guideline on the diagnosis and management of diabetic foot infection. The guideline includes specific recommendations regarding the use of inflammatory markers, tissue and bone culture, and imaging studies in the diagnosis of diabetic foot infection, as well as the indications for surgical debridement and hospitalization. Here, 2 experts in this field, an infectious diseases physician and a podiatrist, debate how to manage the case of a diabetic patient with foot infection. They discuss diagnostic and treatment challenges in the care of this population.
