Assessment of the diabetic foot in inpatients.

Abstract

Diabetic foot disease is a severe complication of diabetes, leading to significant morbidity and lower limb amputations. This review explores the pathophysiology of diabetic foot disease, highlighting the roles of peripheral neuropathy, peripheral arterial disease and immunosuppression in the development of foot ulcers and infections. Key intrinsic and extrinsic risk factors, including long-standing diabetes, poor glycaemic control, inappropriate footwear and trauma are discussed. The importance of comprehensive diabetic foot assessments using diagnostic tools such as the Ipswich Touch Test and Doppler studies is emphasised for early detection and management. Challenges such as delays in referral to specialist care, limited access to multidisciplinary foot teams, and staffing shortages are identified as critical barriers to effective care. The review builds upon extant literature by integrating the most recent evidence, including the 2023 guidelines from the International Working Group on the Diabetic Foot. It emphasises practical application, detailed referral pathways and multidisciplinary care strategies, offering updated tools and insights to improve clinical outcomes and address the often overlooked aspects within inpatient services. Future directions encompass advances in imaging, telemedicine and patient education, which may further optimise preventive and therapeutic strategies for diabetic foot disease.
