The COVIDSurg Collaborative collected data from 140,727 patients in 1,674 hospitals across 116 countries in Asia, North and South America, Europe, Africa and Australia - creating one of the world’s largest and broadest studies on surgery. 

Abstract

CU Medicine and the Hospital Authority in the New Territories East Cluster joined more than 15,000 surgeons across the world as part of the COVIDSurg Collaborative to look into the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This is one of world’s largest and broadest studies on surgery. The study showed that surgery should be delayed for seven weeks after a patient confirmed positive for COVID-19 – as operations carried out within six weeks after diagnosis are associated with increased risk of death. Publishing their findings in Anaesthesia, researchers also discovered that patients are 2.5 times more likely to die if the operations were performed within the six weeks window following a positive diagnosis for SARS-CoV-2.
