The objectives of this study are to evaluate the accuracy of existing methods and to propose a new method. Methods Four existing methods were used to identify all patients diagnosed with a foot ulcer in a Department of Veterans Affairs VA hospital from the inpatient and outpatient datasets for 2003. Their electronic medical records were reviewed to verify whether the medical records positively indicate presence of a diabetic foot ulcer in diagnoses medical assessments or consults. For each method five measures of accuracy and agreement were evaluated using data from medical records as the gold standard. Results Our medical record reviews show that all methods had sensitivity 92 but their specificity varied substantially between 74 and 91 . A method used in Harrington et al. 2004 was the most accurate with 94 sensitivity and 91 specificity and produced an annual prevalence of among VA users with diabetes nationwide. A new and simpler method consisting of two codes and shows an equally good accuracy with 93 sensitivity and 91 specificity and prevalence. Conclusions Our results indicate that the Harrington and New methods are highly comparable and accurate. We recommend the Harrington method for its accuracy and the New method for its simplicity and comparable accuracy. Background With the rapid spread of electronic .
