NICE Guidance People with diabetes at high risk of foot ulcers i.e. with neuropathy and absent pulses, or other risk factors, should be reviewed every 1-3 months.1 Care of people at increased risk of foot ulcers1 Low risk – Foot care education Increased risk - Enhance foot care education High risk – Skin and nail care NICE recommendations1 ‘To improve knowledge, encourage beneficial self care, minimize inadvertent self-harm, HCPs should discuss and agree with patients a management plan that includes appropriate foot care.’ Reference: NICE Clinical guidance for type 2 diabetes CG10.

Skin care advice and support Use moisturising cream every day and wear well-fitting shoes that protect and support your feet.1 xxxx Cream BP is very good and not expensive. What is the best sort of cream for a Diabetic (T1) to use on their feet to keep them soft and moisturised? Patient forums on line can give conflicting advice, which is not evidence based - but may be convincing! My GP lets me use xxx emollient cream , I too was told not to use this between my toes .

Complete emollient therapy The most important treatment for all dry skin diseases1 Emollient creams and ointments Emollient wash products Emollient bath and shower products ‘Everything that goes on the skin should be emollient based and all soaps replaced with emollient wash products’ However diabetes need specific treatment tailored especially for their feet Reference: Cork MJ & Danby S (2009) A renaissance in emollient therapy. British Journal of Nursing;18:872-77 OCCLUSIVE EMOLLIENTS PROVIDE A LAYER OVER THE SURFACE OF THE SKIN Occlusive emollient cream Occlusive emollient creams leave a fine occlusive layer of non-physiologic lipid or oil over the skin surface e.g. petrolatum or mineral oil The occlusive layer reduces water loss from the stratum corneum Occlusive emollient ointment Occlusive emollient ointments contain a lot more oil and provide more occlusion over the surface Occlusive emollient ointments are extremely greasy and are cosmetically unacceptable to many people Reference: Cork MJ & Danby S (2009) A renaissance in emollient therapy. British Journal of Nursing;18:872-77 7. Emollients containing urea help compensate for the reduced levels of NMF in dry skin Emollients containing NMFs such as urea, produce similar rehydration effects to heavy emollients1 NMF emollient1 Urea attracts and holds water in the stratum corneum and helps compensate for reduced levels of NMF associated with dry skin2 NMF-containing emollients have greater cosmetic acceptability than heavy emollients due to their low oil content, and require less frequent application than occlusive emollients1 Reference: Cork MJ & Danby S (2009) A renaissance in emollient therapy. British Journal of Nursing;18:872-77 Foam humectant creams– a new innovative formulation Normal skin functions are maintained Formulation benefits with a twodimensional protective mesh Skin is protected & stays intact Absorbs quickly & no occluding layer is formed Contains 5% or 10% urea for hydration and reducing TEWL No increase in bacterial growth, in between the toes Can be used on whole foot, around wound edges and in between the toes FOAM CREAMS ARE UNIQUE IN PROTECTING AGAINST THE REAL RISK OF INFECTION BETWEEN THE TOES Evidence: Rapid onset of action - Skin continues to be moisturised throughout the day Improvement in Skin Moisture Content * Source: Prophylaxis using foam creams in various dermatological indications – R. Rudolph, Norden Conclusions Treating dry skin promptly is a key element in preventing dry cracked skin, which can result in complications in the diabetic foot NICE recommends foot care education for all patients with diabetes Informed patient choice of emollient formulation is crucial, to address all areas of dry skin on the foot and promote self-management Foam humectant creams are the only formulations clinically and medically approved for use on the entire foot, including between the toes for people with diabetes Foam creams are innovative formulations which increase patient acceptance and compliance Thank you for listening Any Questions?
