Role of Hemoglobin A1c as Predictor of Foot Ulcer Healing in Diabetes
Background: Diabetic foot ulcers are associated with substantial morbidity and mortality in diabetic patients. The role of hemoglobin A1c (HbA1c) in assessing the outcome of diabetic ulcer needs to be evaluated. Aim: This study aims to assess the validity and effectiveness of HbA1c to predict foot ulcer healing in diabetic patients. Materials and Methods: This study was conducted in the Department of Surgery, Akash Institute of Medical Sciences and Research Centre, Devanahalli, over 24-month period from February 2015 to February 2017. A descriptive study was carried out in 280 diabetic patients with foot ulcers. The data collection included demographics, medical diagnoses, ulcer healing duration, and HbA1c results. Results: About 50% of patients with controlled HbA1c levels had their wounds healed in 3 months, whereas only 20% of patients with high HbA1c had their wounds healed in same time. 15% of patients with high HbA1c had their wounds persisting even after 1 year. Conclusion: HbA1c levels were strongly associated with the process as well as the duration of foot ulcer healing in the diabetic patients. Elevated HbA1c was associated with poor prognosis in terms of foot ulcer healing.
