Foot ulcer prevention plays a crucial role in reducing the amputation rate among diabetic patients. With regard to the prevention of diabetic foot ulcers, the 2023 guidelines of the International Working Group of Diabetic Foot(IWGDF) were different from the 2019 counterpart. The most notable change is the addition of high-level evidence to support recommendations, primarily derived from randomized controlled studies. The 2023 guidelines also advocate for local skin temperature measurement, participation in ankle exercise training, and psychological intervention for foot ulcer prevention. This article conducts a comparative analysis of the two guidelines across six key dimensions: identification of high-risk feet, regular examination of high-risk feet, health education, ensuring appropriate daily footwear, addressing ulcer risk factors, and comprehensive foot care. Drawing from clinical insights, the application and prospective implications of the 2023 guidelines in China are also examined.
