BACKGROUND: We sought to evaluate the relationship between baseline hemoglobin A1c (HbA1c) level and clinical outcomes, including foot ulcer outcome (resolved versus unresolved) and wound-healing time, in individuals with type 2 diabetes.
METHODS: A prospective observational study was conducted on 99 patients presenting with a diabetic foot ulceration. Patient and ulcer characteristics were recorded. Patients were followed up for a maximum of 1 year.
RESULTS: After 1 year of follow-up, 77% of ulcers healed and 23% did not heal. Although this study demonstrated that the baseline HbA1c reading was not a significant predictor of foot ulcer outcome (P = .603, resolved versus amputated), on further statistical analyses, when HbA1c was compared with the time taken for complete ulcer healing in the resolved group (n = 77), it proved to be significant (P = .009).
CONCLUSIONS: These findings have important implications for clinical practice, especially in an outpatient setting. Improving glycemic control may improve ulcer outcomes. Prediction of outcome may be helpful for health-care professionals in individualizing and optimizing clinical assessment and management of patients. Identification of determinants of outcome could result in improved health outcomes, improved quality of life, and fewer diabetes-related foot complications.
