Construction of a nomogram of the risk of recurrence within 1 year after healing of diabetic foot ulcers
Objective To analyze the recurrence of diabetic foot ulcers after healing and construct a risk nomogram model based on influencing factors.Methods A total of 140 diabetic patients who had healed from foot ulcers and were admitted to our hospital from April 2019 to April 2022 were selected as the research objects.Patients were divided into recurrence group(n=54)and non-recurrence group(n=86)according to whether diabetic foot ulcer recurred within 1 year of follow-up.Univariate and multivariate logistic regression analyses were performed to identify factors influencing the recurrence of diabetic foot ulcer after healing.Based on these findinds,a risk prediction model was constructed,and a nomogram was drawn.Results The follow-up completion rate was 93.3%,and the recurrence rate of diabetic foot ulcer within 1 year was 38.57%.Logistic regression analysis showed that age,smoking history,callus,initial plantar ulcer,foot deformity,glycosylated hemoglobin,and C-reactive protein were independent risk factors for the recurrence of diabetic foot ulcer(OR>1,P<0.05),and albumin was an independent protective factor for the recurrence of diabetic foot ulcer(OR<1,P<0.05).Hosemer-Lemeshow goodness-of-fit test:χ2==5.597,P=0.756.The area under the ROC curve was 0.987(95%CI=0.973～0.999,P<0.001),and the sensitivity and specificity were 91.9%and 98.1%,respectively.Conclusion The recurrence of diabetic foot ulcers after healing is affected by multiple factors.The risk prediction model based on these factors demonstrates a good predictive performance.
