A presentation to the Society of Surgical Oncology (2023) international Conference on Surgical Cancer Care reports on a study of nearly 8000 patients who were cared for by 737 anaesthetists and 163 surgeons. It suggests that surgeons and anaesthetists who work closely together have better patient outcomes. Evidence presented suggests that for every additional procedure an anaesthetist and surgeon performed together there was a 5% reduction in the chances of a significant post-operative complication at 90 days (Clavien-Dindo grade 3-5).
