Abstract
Objective: To describe the characteristics of wounds, ischemia, and foot infections classification system (WIfI) in patients with diabetic foot and analyze risk factors relating to the WIfI classification in these patients. Methodology: A cross-sectional descriptive study, 30 patients with diabetic foot disease at Hue Central Hospital from December 19, 2021 to April 29, 2022. Results: Prevalence of amputation risk WIfI classification is 26.7 in stage 1 (VL), 30% in stage 2 (L), 23.3% in stage 3 (M) and 20% in stage 4 (H). The related factors of the WIfI classification stages were HbA1C (p=0.035), ABI (p=0.05), TBI (p=0.01), TP (p=0.01). The regression model is described by the equation: Risk of amputation = 3.701 - 0.788ABI - 1.260TP. Conclusion: It is necessary to apply the WIfI classification for the assessment of patients with diabetic foot in Vietnam, paying special attention to the TP and ABI index.
