In 2015, members of the Association for the Advancement of Wound Care (AAWC), Wound Healing Society, and the Canadian Association for Enterostomal Therapy formed the International Consolidated Guidelines Taskforce to update the AAWC Venous Ulcer Guidelines to the collaborative, intersociety, endorsed International Consolidated Venous Ulcer Guideline. This "guideline of guidelines" integrates recommendations from all relevant, published evidence-based guidelines on venous ulcer care and prevention. The update process was conducted in accordance with the National Guideline Clearinghouse inclusion criteria and was informed by a systematic review of the evidence, with additional content validation of each venous ulcer management recommendation. Twenty-three (23) wound experts participated. Compared to the 2010 version of the guideline, A-level recommendations increased from 62% to 77%, 31 recommendations were removed, and new recommendations included quality of life evaluations and surgical treatment options. Gaps in the evidence and needed areas for research include surgical, topical, and pharmaceutical interventions. Collaboration among societies and stakeholders and rigorous guideline development processes may expedite the implementation of evidence-based practices, fill in research gaps, and provide a powerful unified voice to regulatory and reimbursement agencies with the ultimate goal of improving outcomes for persons with a venous ulcer.
