Foot care assessment in patients with diabetes: a screening algorithm for patient education and referral

The foot care behaviors of patients with diabetes were assessed by medical history, and their feet were examined for peripheral neuropathy, peripheral vascular disease, foot ulcers, and deformities. The sample consisted of 136 patients (14 with insulin-dependent diabetes and 122 with non-insulin-dependent diabetes). Mean age was 61 years and mean duration of diabetes was 13 years. Peripheral vascular disease was found in 25% of the patients, peripheral neuropathy in 33%, and 13% had both peripheral vascular disease and peripheral neuropathy. Potentially unsafe nail and foot care practices were identified, suggesting that routine diabetes care may not provide sufficient foot care education and follow-up for all patients. A screening algorithm was developed to provide guidelines for individualizing foot care education and referral of patients with diabetic foot disease. The recommendations included annual diabetes foot care assessments and education for those at low risk for foot amputation, intensive foot care education and more frequent follow-up for individuals with peripheral neuropathy or peripheral vascular disease, and referral to a foot care specialty clinic for individuals with peripheral neuropathy and peripheral vascular disease, or foot ulcers.
