Improved Survival of the Diabetic Foot: The Role of a Specialised Foot Clinic

A specialized foot clinic for diabetic patients has made a detailed analysis of the presentation of diabetic foot ulcers and from this a new, organised approach to treatment has been derived. Over three years it has achieved a high rate of ulcer healing and reduced the number of major amputations. It has brought together the skills of chiropodist, shoe-fitter, nurse, physician and surgeon to manage the distinctive lesions of the neuropathic and ischaemic diabetic foot. The neuropathic ulcer was invariably associated with callus, whereas the ischaemic ulcer presented as areas of necrosis often from localised pressure of tight shoes. Essential aspects of management are specially constructed shoes, intensive chiropody and precise antibiotic treatment. Healing was achieved in 204 out of 238 (86 per cent) neuropathic ulcers and 107 out of 148 (72 per cent) ischaemic ulcers. Relapse rate in special shoes was 26 per cent compared with 83 per cent who preferred to wear their own shoes. In the two years before the establishment of the clinic, there were 11 and 12 major amputations yearly. This rate has now been reduced to seven, seven and five amputations yearly.
