Every 30 seconds a lower limb is lost somewhere in the world as a consequence of Diabetes. The Lancet Volume 366 Issue 9498 Nice Guideline CG10 Foot care Recall and annual review to detect risks Exam, Test, Palpate, Inspect, Classify Annual Screening Review How to screen and categorise your patient. The Diabetic Foot Peripheral Vascular Disease Important cause of amputation Causative factor of ulceration in 38-52% 50% of all Diabetic amputations (Pacaudet et al 1999) The Diabetic Foot Peripheral Neuropathy • Peripheral neuropathy varies from 12-50% • Young et al 1993 – 28.5% in 6500 pts • Testaye et al 1996 – 28% • Dyck et al 1993 – 13% symptomatic 50% clinical evidence The Diabetic Foot • If can’t feel pressure:- x10 increased risk of foot ulcer or amputation • If also foot deformity x32 increased risk Rith Najarian 1992 Annual Screening review What do we need to screen a patient? • Eyes • Hands • 10g Monofilament Annual Screening Review Symptoms Inspection Examination • Claudication • Callus • Skin Condition • Pain • Deformity • Pulses present • History of ulcer • Ulcer present • Sensitive to 10g pressure • Visual impairment • Mobility problems (loss of 10g = HIGH RISK of ulceration Annual Screening Review Symptoms Inspection Examination • Claudication • Callus • Skin Condition • Pain • Deformity • Pulses present • History of ulcer • Ulcer present • Sensitive to 10g pressure • Visual impairment • Mobility problems (loss of 10g = HIGH RISK of ulceration Annual Screening Review To palpate pulses use 2 fingers not your thumb. Dorsalis Pedis Pulses – can be found in the groove between the 1st and 2nd Metatarsal bones This pulse can be absent in 10% of people Posterior Tibial Pulse – can be found behind the medial malleolus 1/3 of the distance from the medial malleolus to the bottom of the heel, in a hollow. Annual Screening Review Avoid areas of callus or ulceration Deteriorates with use Not to test on more than 10 patients with each monofilament per session • Monofilament requires 24hr rest. •Use approved monofilaments either Bailey’s or Owen Mumford Neuropen Demonstrate on patients forearm or face to ensure they know how it feels. Ask patient to close their eyes before you start and answer YES each time they feel it. Place the tip of the monofilament on the site to be tested. Apply pressure until it bows. Don’t let it slip or slide across the skin or make repetitive contact with the same spot. Test all sites on the screening form. Annual Screening Review Low Risk Normal Flow Protective sensation intact (10g monofilament) Annual Screening Review Moderate Risk +/- arterial disease Loss of protective sensation (10g pressure) • No deformity • No callus • No previous ulcer Annual Screening Review High Risk +/- arterial disease Loss of protective sensation(10g pressure) • Deformity or callus present • No previous ulcer Annual Screening Review Very High Risk +/- arterial disease • Ulcer present • Previous ulcer • Loss of protective sensation (10g pressure) Annual Screening Review Arterial Disease • Abnormal flow • +/- history of claudication
