The Gastroenterological Society of Australia (GESA) initially engaged its members through its regular online communications, sharing the aims of the EVOLVE initiative, as well as background information on the US and Canadian versions of Choosing Wisely. Members were provided with a copy of the five recommendations made by the American Gastroenterology Association. GESA also consulted externally, with the EVOLVE Lead Fellow addressing the GUT club and the Inflammatory Bowel Disease Group on the initiative. All members of GESA were invited to submit proposed items for the Top 5 list. The GESA Council reviewed all items before reaching consensus on the recommended final list. A review of the evidence for the shortlisted items was then undertaken and the final list and its rationales were signed off by the GESA Council in May 2016.
