The WGO Guidelines Library contains practice guidelines written from a viewpoint of global applicability. WGO Guidelines are available in English, Spanish, Portuguese, French, Mandarin, and Russian. WGO Guidelines go through a rigorous process of authoring, editing, and peer review and are as evidence based as possible. Ultimate responsibility and editorial control lies with the WGO Guidelines Committee.
While each guideline includes references to other relevant guidelines, WGO is the only organization who has adopted a global focus. Cascade-based WGO guidelines offer different options for diagnosis and treatment depending on the available resources.
A hierarchical set of diagnostic or therapeutic techniques for the same disease, ranked according to the resources available. Learn how the addition of ‘Cascades’ to guidelines increases their impact in large parts of the world in this article by Drs. Michael Fried, MD, and Justus Krabshuis.
WGO Guidelines are globally applicable by the nature of their cascades, which identify other ways of achieving the best possible outcome by taking the available resources into account. In addition, each guideline review team includes non-Western experts with direct knowledge of conditions in their regions.
