What is the International Working Group on the Diabetic Foot (IWGDF)?
The International Working Group on the Diabetic Foot (IWGDF) is a global multidisciplinary organization that develops and publishes evidence-based guidelines for the prevention and management of diabetic foot disease, serving as the primary international authority for standardizing diabetic foot care worldwide. 1, 2
Organizational Structure and Mission
The IWGDF was founded in 1996 and became a Consultative Section of the International Diabetes Federation (IDF) in 2000, later integrating as part of the IDF programme as the IDF Diabetic Foot Programme in 2010. 2 The organization's core objective is to reduce the global burden of diabetic foot disease through cost-effective, quality healthcare based on evidence-based medicine principles. 2
Global Reach and Implementation
- The IWGDF currently has representatives from more than 100 countries worldwide, ensuring global implementation and adaptation of guidelines to local contexts. 2
- Guidelines have been translated into 26 languages and distributed in over 80,000 copies globally, with current translations serving approximately 2.9 billion people in their native languages. 2, 3
- The organization recruits local champions as members to facilitate implementation of the International Consensus in their respective regions. 2
Guideline Development Process
The IWGDF has published comprehensive evidence-based guidelines since 1999, with systematic updates every 4 years. 2, 3, 4 The most recent update was published in 2023. 5, 4
The guideline development follows rigorous methodology:
- Working groups of independent multidisciplinary experts conduct systematic reviews of medical literature. 2
- Since 2023, the IWGDF uses the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) framework to formulate clinical questions in PICO/PACO format and develop recommendations. 5, 6
- Recommendations are based on evidence quality, expert opinion when evidence is lacking, and consideration of benefits versus harms, patient preferences, feasibility, applicability, and costs. 5, 7
- All recommendations undergo thorough review by IWGDF representatives globally before endorsement. 2
Scope of Guidelines
The 2023 IWGDF Guidelines cover seven major topics: 4
- Prevention of foot ulcers
- Classification of diabetic foot ulcers
- Offloading interventions
- Peripheral artery disease (developed in collaboration with European Society for Vascular Surgery and Society for Vascular Surgery) 6
- Infection management
- Wound healing interventions
- Acute Charcot neuro-osteoarthropathy (new guideline added in 2023) 5, 4
Clinical Impact and Significance
Every 30 seconds, a lower limb is lost to diabetes somewhere in the world, with more than 1 million people with diabetes losing a leg annually. 2 The IWGDF addresses this devastating burden by:
- Providing standardized approaches to foot ulcer evaluation and treatment that have been associated with decreased amputation rates globally. 1, 4
- Establishing five key prevention elements: identification of at-risk feet, regular inspection, education, appropriate footwear, and treatment of pre-ulcerative signs. 1
- Defining seven key ulcer treatment elements: pressure relief, perfusion restoration, infection treatment, metabolic control, local wound care, education, and recurrence prevention. 1
Resource Requirements and Volunteer Effort
The 2023 guideline update required an estimated 10 years of full-time work from over 100 experts across more than 60 countries, representing approximately 2 million euros in volunteer time if financially compensated. 3 This demonstrates the extraordinary commitment of the international diabetic foot community to advancing evidence-based care.
Practical Implementation Tools
The IWGDF provides practical implementation resources including:
- Risk stratification systems with specific examination frequencies (ranging from annual for very low risk to every 1-3 months for high risk patients). 8
- Standardized definitions and criteria for diabetes-related foot disease to facilitate clear communication between disciplines and countries. 9
- Classification systems for different clinical purposes, including the SINBAD system for communication and the IDSA/IWGDF classification for infection assessment. 10
