BACKGROUND: To determine the prevalence of risk factors for diabetic foot ulceration in diabetic patients free of active pedal ulceration in a hospital setting. METHODS: In sixteen French diabetology centres, a survey was conducted on a given day in all diabetic people attending the units, both as in- or out-patients. RESULTS: 664 patients were evaluated: 105 had an active foot ulcer and were excluded from the analysis as were four other patients due to lack of reliable data. From the 555 assessable patients, 40 (7.2%) had a history of foot ulcer or lower-limb amputation. Sensory neuropathy with loss of protective sensation, as measured by the 5.07 (10 g) Semmes-Weinstein monofilament testing, was present in 27.1% of patients, whereas 17% had a peripheral arterial disease mainly based on the clinical examination. On addition, foot deformities were found in 117 patients (21.1%). According to the classification system of the International Working Group on the Diabetic Foot, 72.8% of patients were at low-risk for pedal ulceration (grade 0) and 17,5% were in the higher-risk groups (grade 2 & 3). If patients with isolated peripheral arterial disease were considered as a separate risk group (as was those with isolated neuropathy), percentage of low-risk patients decreased to 65.6%. There was a clear trend between the increasing severity of the staging and age, duration of diabetes, prevalence of nephropathy and retinopathy. CONCLUSIONS: Prevalence of risk factors for foot ulceration is rather high in a hospital-based diabetic population, emphasising the need for implementing screening and preventive strategies to decrease the burden of diabetic foot problems and to improve the quality of life for people with diabetes.
