Diabetic Foot Ulcer Beyond Wound Closure: Clinical Practice Guideline

Abstract

A total of 37.3 million Americans have diabetes, and 96 million more have prediabetes. Hyperglycemia, the hallmark of diabetes, increases the risk for diabetes-related complications, including skin breakdown and cardiovascular disease. Many clinical practice guidelines exist, but there are gaps regarding the best approaches to assess physical fitness and mobility in adults with diabetes; incorporate exercise into the care plan; and reload the diabetic foot after ulcer closure has occurred to avoid ulcer reoccurrence. The purpose of this clinical practice guideline was to review and assess previously published guidelines and address gaps within the guidelines specific to the following: best screening tools/tests and interventions to prevent a future reulceration, best screening tools and interventions to assess and address mobility impairments, best tools to measure and interventions to address reduced physical fitness and activity, best approach to reloading the foot after ulceration closure and, finally, whether improvement in physical fitness will positively change quality of life and health care costs. The Guidelines Development Group performed a systematic literature search and review of the literature. A total of 701 studies were identified. Following duplicate removal and exclusion for irrelevance, 125 studies underwent full-text review, and 38 studies were included. Recommendations were developed using a software assistant created specifically for guideline recommendation development. Recommendations resulted for physical fitness and activity inclusion and measurement for adults with diabetes and with or without foot ulceration. Exercise and physical activity should be prescribed according to the physiologic response of an adult with diabetes to exercise and preferences for optimizing long-term quality of life and reduce health care costs. Reloading following diabetic foot ulcer closure should include maximal offloading, especially during the first 3 months; loading should be titrated using a footwear schedule. Further research is necessary in the areas of exercise in the wound healing process and the assessment of methods to reload a newly reepithelialized ulcer to prevent recurrence.
