Abstract：Objective To identify the factors related to prognosis of diabetic foot ulcer (DFU).Methods A total of 186 patients with type Ⅱ DFU from a single diabetic foot center was included in this prospective study.Follow-up of the final outcome (healing,major amputation or death) was made in 6 months.Influence of patient demographics and clinical data on outcome was detected using multivariate Logistic regression analysis.Results Follow-up was performed in 172 patients,of whom 147 were cured (55 cases cured after minor amputations),3 underwent major amputations,6 died,and 16 were not yet cured at the final follow-up.In multivariate Logistic regression analysis,the outcome was independently correlated with ischemia (P ＜0.01),infection (P ＜0.05),ulcer number (P ＜ 0.01) and peripheral neuropathy (P ＜ 0.05) ; the risk of poor outcome increased with ischemia [odds ratio (OR) =10.8],infection (OR =211.4),ulcer number (OR =39.5),and peripheral neuropathy (OR =181.1).Conclusion Prognosis of DFU is associated with ischemia,infection,ulcer number,and peripheral neuropathy.
