Diabetes mellitus and the elderly: special considerations for foot ulcer prevention and care.

The risk of lower extremity amputation in persons with diabetes mellitus increases with advanced age, necessitating clinical vigilance. Individualized and comprehensive prevention efforts are required to address the complicated and diverse nature of the diabetic foot in the elderly patient, including promotion of lifestyle changes to offset diabetes, attention to cognitive deficits and economic limitations, and provision of foot care education and management (eg, emphasizing the need for appropriate foot wear). If an ulcer develops, physiologic and socioeconomic factors may influence its clinical presentation, assessment, diagnosis, and treatment.
