Diabetic foot ulcers in the Hong Kong Chinese population: retrospective study.

OBJECTIVE To assess the predictive power of various parameters on the final outcome of ulcerated diabetic feet among the Hong Kong Chinese population. DESIGN Retrospective cohort study. SETTING Regional public hospital, Hong Kong. PATIENTS Medical records of 340 diabetic patients with foot ulcers (535) who were referred to the Diabetic Foot Clinic between July 1995 and June 2000 were reviewed. MAIN OUTCOME MEASURES Demographic and clinical data, including assessment of the foot and blood parameters. RESULTS Increasing age, wound depth, the presence of ischaemia, a low albumin level, and the lack of simultaneous ulceration were determined by stepwise logistic regression analysis to be the most significant independent predictors of an unfavourable outcome. CONCLUSIONS Major amputation is more likely to occur in elderly patients, with progressive wound depth, and in the presence of ischaemia. A low albumin level was also noted to be an independent predictor of major amputation in the population studied.
