Risk factors associated with healing chronic diabetic foot ulcers: the importance of hyperglycemia.
Diabetic foot ulcer management presents a significant challenge for wound care clinicians; numerous approaches to encourage healing in these difficult wounds have been explored. To determine risk factors related to diabetic foot ulcer time to healing and closure, a secondary analysis of data from a prospective randomized study involving 245 patients treated with a bioengineered human dermal substitute (n = 130) or control treatment (n = 115) was conducted. Analyzed variables included age, race, gender, ulcer duration, initial ulcer size, initial hemoglobin (HgbA1c), average HgbA1c, change in HgbA1c, diabetes type, average hours of weight-bearing, study ulcer infection, history of smoking or alcohol use, and laboratory values. ⋯ Female gender, small ulcer size, and the absence of infection were found to have a positive effect on healing all diabetic foot ulcers; improved glucose control had a significant effect on healing wounds managed with the dermal substitute only. This is the first diabetic foot ulcer study to find a relationship between hyperglycemia and wound healing. Further research into factors that improve healing of wounds, including diabetic foot ulcers, is warranted.
