Insights
Predicting diabetic foot ulcer outcomes is crucial. Key factors for poor outcomes in Hong Kong Chinese patients include older age, deep wounds, ischemia, and low albumin levels.
Area of Science:
- Diabetology
- Podiatry
- Vascular Surgery
Background:
- Diabetic foot ulcers are a significant complication of diabetes mellitus.
- Effective prediction of outcomes is vital for patient management and resource allocation.
Purpose of the Study:
- To identify predictors of poor outcomes in ulcerated diabetic feet.
- To assess the influence of various clinical and demographic factors on final outcomes in the Hong Kong Chinese population.
Main Methods:
- Retrospective cohort study design.
- Analysis of medical records from 340 diabetic patients with foot ulcers treated between 1995 and 2000.
- Inclusion of demographic, clinical, and blood parameters for assessment.
Main Results:
- Stepwise logistic regression identified significant predictors of unfavorable outcomes.
- Independent predictors included increasing age, wound depth, presence of ischemia, low albumin levels, and lack of simultaneous ulceration.
Conclusions:
- Elderly patients with progressive wound depth and ischemia face higher risks of major amputation.
- Low albumin levels are independently associated with an increased likelihood of major amputation in this population.
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.
