糖尿病足是糖尿病患者常见的并发症之一，也是导致患者截肢和死亡的重要原因。根据中华糖尿瘸杂志2019年2月第11卷第2期发表的研究，我国制定了《中国糖尿病足防治指南（2019版）》，为糖尿病足的预防和治疗提供了全面的指导。

该指南以最佳临床证据为基础，结合专家经验，制定了糖尿病足的诊治流程。主要包括三个部分：糖尿病足的流行病学数据以及早期筛查与预防、糖尿病神经病变和下肢血管病变的规范化诊治流程、糖尿病足感染的规范化诊治流程、以及全身营养、心理状态和中医中药的治疗进展。

本指南参考了大量国内外研究进展，首次详细地从糖尿病足防治的各个方面进行了阐述。这对于规范我国糖尿病足的诊断和治疗，降低糖尿病足的发病率和死亡率，提高患者的生活质量具有重要意义。

糖尿病足的流行病学现状显示，全球糖尿病足溃疡的患病率约为6.3%，男性高于女性，2型糖尿病高于1型糖尿病。我国糖尿病足溃疡的年发病率为8.1%，年复发率为31.6%，年死亡率为14.4%。糖尿病足的预后很差，甚至比除肺癌、胰腺癌等以外的大多数癌症的病死率和致残率还高。因此，早期筛查并矫正糖尿病足病危险因素对避免及延缓糖尿病足的发生具有关键作用。

screening and prevention of diabetic foot

Early screening and correction of risk factors for diabetic foot disease play a crucial role in avoiding and delaying the occurrence of diabetic foot. The screening should include the following aspects:

1. Assessment of diabetes mellitus control, including blood glucose, blood lipids, and blood pressure.

2. Evaluation of peripheral neuropathy and vascular disease, including nerve conduction velocity testing, ankle brachial index measurement, and Doppler ultrasound examination of the lower extremities.

3. Assessment of foot deformities and ulceration, including physical examination and imaging examination such as X-ray, CT, or MRI.

4. Detection of foot infections, including wound culture and sensitivity testing.

5. Assessment of nutritional status, psychological state, and traditional Chinese medicine treatment.

The prevention and treatment of diabetic foot disease is a comprehensive task that requires the cooperation of various medical specialties. The “Chinese Guideline for the Prevention and Treatment of Diabetic Foot (2019 Edition)” provides a clear and feasible strategy for the prevention and treatment of diabetic foot disease, which is of great significance for reducing the incidence and mortality of diabetic foot disease and improving the quality of life of patients.
