ABSTRACT


Title: A Risk Scoring System for Predicting Major Amputation in Patients with Diabetic Foot

Objective: To develop a risk scoring tool to predict the risk of major lower limb amputations among diabetic foot patients using demographic and clinical parameters
Study Design: The study is a retrospective cohort analytic design which uses charts reviewed from January 2008 to June 2013.
Summary of Background Data: Diabetic patients present a relative risk of having to undergo an amputation over the course of their lives that is 15 to 40 times greater than for non-diabetic individuals. Risk identification is fundamental for an effective preventive management of diabetic foot problems. Hence, the goal of this study is to identify diabetic foot patients at risk for major amputation and facilitate preventive management by formulating a risk scoring system for predicting major amputation.
Methods: A 6-year retrospective charts review from January 2008 to June 2013 at the De La Salle University Medical Center was used for the study. All patients with a final diagnosis of diabetic foot on the chart, with an ICD-10-CM Index of E11.621, were included in the study. These were then divided into major and minor amputations.
Results: The risk factors for major amputation were Wagner Classification, WBC count, Erythrocyte Sedimentation Rate (ESR) and C-reactive protein (CRP).
Conclusion: From the risk factors noted, the proponent has devised a risk scoring system in predicting major amputation, as follows:
Predicted risk of major amputation = 1/{1 + exp -[-12.026 + (1.998 x Wagner
classification) + (0.755 x 1 for CRP of >200, otherwise 0) + (0.0272 x ESR) +
(0.0725 x WBC)]
