CovidSurg will capture real-world international data, to determine 30-day mortality in patients with COVID-19 infection who undergo surgery. This shared international experience will inform the management of this complex group of patients who undergo surgery throughout the COVID-19 pandemic, ultimately improving their clinical care.

There is an urgent need to understand the outcomes of COVID-19 infected patients who undergo surgery. Capturing real-world data and sharing international experience will inform the management of this complex group of patients who undergo surgery throughout the COVID-19 pandemic, improving their clinical care.

The primary aim of the study is to determine 30-day mortality in patients with COVID-19 infection who undergo surgery. In doing so, this will inform future risk stratification, decision making, and patient consent.

CovidSurg is an investigator-led, non-commercial, non-interventional study is extremely low risk, or even zero risk. This study does not collect any patient identifiable information (including no dates) and data will not be analysed at hospital-level.

Inclusion Criteria:

• Patients undergoing ANY type of surgery in an operating theatre, this includes obstetrics

AND

- The patient had COVID-19 infection either at the time of surgery or within 30 days of surgery, based on

(i) positive COVID-19 lab test or computed tomography (CT) chest scan

OR

(ii) clinical diagnosis (no COVID-19 lab test or CT chest performed)

Exclusion Criteria:

• If COVID-19 infection is diagnosed >30 days after discharge, the patient should not be included.
