Objective To investigate the correlation between the Controlling Nutritional Status (CONUT) score and wound repair of diabetic foot ulcer (DFU).
Methods A total of 80 DFU patients treated in the Hospital from November 20, 2019 to November 20, 2022 were randomly selected as the study objects and divided into non-wound repair group (n=47) and wound repair group (n=33) based on wound repair status. Wound repair and hospital stay were recorded; clinical characteristics and the CONUT score were compared between the wound repair group and the non-wound repair group; the influencing factors of DFU wound repair were analyzed by the multivariate Logistic regression model.
Results The hospital stay of patients in the non-wound repair group was 16.00 (10.50 to 24.00) days, which was significantly shorter than 44.00 (31.00 to 61.80) days of patients in the wound repair group (P < 0.05). The total cholesterol (TC), ankle-brachial index (ABI), the CONUT score, and malnutrition rate of patients in the non-wound repair group were significantly higher than those in the wound repair group (P < 0.05). The results of multivariate Logistic regression analysis showed that the CONUT score, malnutrition, TC and ABI were the independent risk factors for wound repair of DFU (P < 0.05).
Conclusion Malnutrition, ABI, TC and CONUT score in DFU patients can adversely affect wound repair, and the CONUT score can accurately predict the risk of wound repair in patients, serving as a reliable reference for clinicians in early assessment of DFU.
