Once a patient with diabetes develops a foot ulcer 80% are likely to have a lower limb amputation in the future. Amputation carries a considerable burden of cost and impaired quality of life (QOL) and is associated with a 5-year mortality rate of 70%. Once a patient develops an ulcer they remain at high risk for life and are likely to suffer considerable morbidity, debilitation, reduced quality of life and numerous attendances with health care professionals including emergency hospital presentation. There are significant costs associated with the management of diabetes foot ulcers (DFU) which accounts for £1 billion of NHS funding and an average weekly care cost of £208 per person. Both diabetes ulcers and amputation for the most part are preventable providing that patients have effective glycaemic control, regular foot assessments, care for their feet appropriately and wear appropriate footwear or orthotic wear to prevent ulceration.~The focus of this initiative is to utilise digital capability by 3D scanning systems in the community for the provision of highly cost-effective 3D printed soles for shoes which distribute the pressure on the feet whilst having the flexibility of being used in general footwear, thus improving compliance. The cost of these soles is very low at approximately £40 for two pairs. More complex orthotics cost on average £525 each. Scanners and software are likely to be offered free if this is scaled up. The investigators are proposing to work closely with podiatrists in local foot protection services to assess a number of patients at high risk of foot ulcer and deliver a care bundle, which will include assessment, education around both foot care and promoting structured education and 3D sole provision.~The study aims to assess reduction in the rate of diabetic foot ulcers in patients with high-risk diabetic feet using 3D printed insoles compared to standard care. The secondary outcome measures will be improvement in standardised QOL measures. 450 diabetes patients with high-risk feet would be recruited who would be prepared to wear the custom made 3D printed insoles on a regular basis (Intervention group). The control group will be formed of 450 diabetes patients with high-risk feet who will receive standard care.
This is a primary prevention study which aims to assess reduction in the rate of diabetic foot ulcers in patients with high-risk diabetic feet using 3D printed insoles compared to standard care
