Foot Burns and Diabetes: A Systematic Review of Current Clinical Studies and Proposal of a New Treatment Algorithm

This study aims to systematically identify studies that evaluate lower extremity burn injury in the diabetic population, evaluate their clinical course and patient outcomes, and present a treatment algorithm tailored to diabetic burn patients. Our systematic review of the PubMed and Web of Science databases yielded 429 unique articles. After exclusion and inclusion criteria were applied, 59 articles were selected for evaluation. In diabetic patients, the thermal injury was largely a result of decreased awareness and education regarding heat therapies in the context of peripheral neuropathy. All noncase studies found that metrics such as hospital length of stay, ICU admission rates, rates of comorbidity, complication rates, scald injuries, infection rates, and cost of treatment were significantly increased in the diabetic burn population as compared to their nondiabetic counterparts. Where infection was present, microorganisms colonizing diabetic burn wounds were different than those found in the burn wounds of immunocompetent individuals. Operative intervention including split-skin graft, amputation, and debridement were more often utilized in diabetic burn patients. Foot burns in diabetic patients pose unique clinical risks to patients, and as such need to be an alternate treatment protocol to reflect their pathology. Education and training programs are crucial in the prevention of diabetic foot burns to avoid complications, protracted healing, and adverse outcomes. A unique algorithm can guide the unique treatment of this clinical entity.
