Avoid unnecessary perioperative fasting for elective general surgical procedures.

Fasting after midnight used to be the standard of care before surgery, with thought to reduce pulmonary aspiration risk with an empty stomach. There is adequate data that prolonged fasting is associated with increased perioperative insulin resistance, delayed recovery and poorer outcomes. Based on this, the American Society of Anesthesiologists and other organizations recommend refraining from solid food for 6 hours before surgery, while intake of clear fluids is permitted until 2 hours before surgery.

How The List Was Created

The SAGES Quality, Outcomes and Safety (QOS) Committee appointed a task force (composed of active members of the committee) to develop a list of potential recommendations after being provided with information and links to the Choosing Wisely® website. This group compiled a list of recommendations which fit the criteria outlined by the ABIM Foundation. A literature search was performed to ensure the recommendations were evidence-based. The task force then distributed the list to the full membership of the SAGES QOS Committee, asking the members of the committee to rank the recommendations by level of importance and clinical relevance. The top recommendations were discussed by the committee and selected for inclusion in this list. The list was reviewed and approved by the SAGES Executive Committee and SAGES Board of Governors.
