CovidSurg-3: Outcomes of Surgery in COVID-19 Infection

COVID-19 has significant detrimental impacts on surgical systems and patient outcomes. CovidSurg has provided the best available evidence to guide delivery of safe surgery during the pandemic. However, CovidSurg data were collected in 2020 when the wildtype SARS-CoV-2 virus was dominant, and therefore there is a need to for renewed rapid data to guide global practice during Omicron COVID-19 waves. CovidSurg-3 is an extension to CovidSurg and was initiated in response to the emergence of the Omicron variant. CovidSurg-3 has two separate components: * Patient-level component: Collection of outcome data for patients with peri-operative SARS-CoV-2. * Hospital-level component: Collection of aggregated case-mix data. Hospitals in countries with low community SARS-CoV-2 infection rates can contribute towards this component.
