Original study: SARS-CoV-2 infection and venous thromboembolism after surgery: an international prospective cohort study – Anaesthesia

ASA Guidance: Preoperative testing for COVID-19 is essential, regardless of vaccination.

Position statement: Perioperative management of post-COVID-19 surgical patients.

Guideline: SARS‐CoV‐2 infection, COVID‐19 and timing of elective surgery

Study from 116 countries suggests surgery should be delayed for at least seven weeks following a COVID-19 diagnosis to reduce mortality risk

Cohort study: Postoperative in-hospital mortality of patients with COVID-19 infection was more than double that in patients without COVID-19
