602 Foot burns in diabetic patients: A single center experience

Abstract

Introduction: The most significant sequelae of foot burns in diabetic patients is a non-healing wound that results in a diabetic foot ulcer, which has been a predictor for need for amputation and mortality. Even minor amputations in patients with diabetes have a significant mortality rate. Our systemic review found that when 60% of a diabetic patient cohort with foot burns was managed by skin grafting, 29% subsequently required amputations, which is concerning. The practice at our regional burn center has been to manage patients with foot burns and diabetes non-operatively with daily dressing changes, and we believe that this may result in better functional outcomes, ambulatory status, and lower amputation rates. Methods: A retrospective review of patients with diabetes and foot burns admitted to an ABA verified regional burn center was conducted. The primary outcome was amputation. Secondary outcomes were ambulatory status, wound closure, and infection. Rank sum and fisher exact tests were performed to compare patient demographics, comorbidities, uncontrolled DM (A1c >9%), and burn characteristics between patients who were treated surgically and those who received daily wound care only. These associations were subsequently evaluated with odds ratios (OR) and 95% confidence intervals (CI). A multivariable logistic regression was performed to evaluate for possible differentiating factors that resulted in maintaining ambulatory status at completion of burn care. Statistical significance was defined as p
