Detailed contents and aims of an educational intervention for diabetic foot are presented, together with evaluation tools and results at 3, 6 and 12 month interval after the course. Knowledge level and "health" of the foot were assessed at 12 month interval on 2/3 of the 100 diabetic patients originally exposed to the educational intervention. After 12 months 80% of patients showed a good retention of knowledge on practical issues related to foot care, while 77% of patients with persistent foot problems were not independent (because of hypo-mobility or sight problems) in foot care.
