Chronic wounds pose an ongoing challenge for clinicians, and there needs to be a clearer understanding of the pathophysiology of wound chronicity and treatment modalities available.

Diabetes-related foot complications, including diabetic foot ulcers (DFUs), are leading causes of non-traumatic lower extremity amputation. Of the approximately 420 million adults in the United States with diabetes mellitus, one fourth will develop at least one DFU.1,2 DFUs are preceded by a compendium of risk factors, including the presence of neuropathy, external trauma, infection, effects of ischemia from concomitant peripheral arterial disease, malnutrition, and poor hygiene or self-care, among others. In 80% of patients, DFU is a precursor to some degree of lower extremity amputation.3 And, for these patients who have undergone amputation, their risk for further amputation becomes double that of a patient without diabetes. The mortality rate following a diagnosis of diabetic foot ulceration is 5% in the first year. The five-year mortality rate is 50% and rises to 70% after amputation.4 Once healed, 40% of DFUs will recur within 12 months, nearly 70% at three years, and nearly 75% at five years.5

These recommendations are aligned with the Infectious Disease Society of America 2012 practice guidelines and the 2016 joint guidelines of the Society for Vascular Medicine and the American Podiatric Medical Association. Multidisciplinary care is crucial for patients with DFU, and it should be carried out by a multidisciplinary team, with the previously reviewed items included as a total plan of care. Even after a patient’s ulceration is resolved, the patient is at high risk for DFU recurrence. Some literature has begun to refer to this resolution as “remission,” which better captures the concept that ulceration may recur. Long-term goals are to engage the patient in adequate preventive care and encourage the patient’s maximum activity levels.11
