Registration and Redcap

  • Registration for CovidSurg and CovidSurg-Cancer has now closed. Future studies are currently being designed and details on how you can register for these will be made available in due course.

  • Please follow the steps on this form to register and / or gain REDCap access.

  • Please allow 24-48 hours to receive your login and remember to check your junk/spam folder.

  • No. Where possible we are issuing only ONE SINGLE REDCap login per site.

  • The login details can be shared with all members of your team who will be responsible for uploading patient data. We encourage teamwork to identify patients and upload data, to increase data accuracy.

  • If you believe your hospital would benefit from having more than one account (e.g. large hospital with multiple teams collecting data separately), please email us ([email protected]) and we issue more than one login if appropriate.

  • We can consider requests from sites requiring additional logins (e.g. for very large teams, or for teams working across different sites).

  • To request this, please contact [email protected].

  • Yes – to help sub-teams within hospitals to navigate faster to only relevant records we have created a speciality-specific dashboard on REDCap. Here you can select the sub-study in which you are participating and see only those patient records.

  • A short tutorial video on how to navigate the dashboard can be found at:

  • Collaborators can be added via the authorship project on REDCap.

  • You can contact [email protected]com. Our team will be able to confirm your username and arrange a password re-set for you.

Inclusion criteria for COVIDSURG COHORT study

You should include patients diagnosed with SARS-CoV-2 infection within 7 days before or 30 days after surgery (via lab test, computed tomography scan or clinical diagnosis in the absence of the previous). Patients being diagnosed outside of this time-window should be excluded from CovidSurg cohort study.

No – it is based on the diagnosis made by a senior doctor according to clinical judgement. This will be accepted as COVID-19 diagnosis only when lab tests or CT scans are not available/performed.

No – only confirmed SARS-CoV-2 positive patients should be included. When the test is negative, the patient should be excluded.

Yes – if a post-operative COVID-19 diagnosis was made up to 30 days after surgery. Please
collect details about COVID-19 diagnosis (lab test, CT scan or clinical diagnosis if no testing

Patients with a negative test should be excluded from CovidSurg Cohort Study. Even if they have clinical symptoms which could be COVID, the test (swab or CT) is the inclusion criteria.

Patients undergoing a procedure performed by a surgeon in an operating theatre should be included.

  • Percutaneous procedures (e.g. insertion of central venous catheters, interventional radiology procedures).

  • Bedside procedures (e.g. in the intensive care unit, unless due to the pandemic operations are routinely being performed in the intensive care unit that would normally be performed in theatre).

No – percutaneous procedures are excluded.

The index operation should be taken as the first operation that took place in the 30 days preceding their diagnosis.

The index operation should be taken as the first operation they had after SARS-CoV-2 diagnosis (this operation should be within 7 days of SARS-CoV-2 diagnosis in order for the patient to be eligible for inclusion).

Yes – you can retrospectively collect data about patients who previously underwent surgery and were diagnosed with SARS-CoV-2 infection within 7 days before or 30 days after surgery (via lab test, computed tomography scan or clinical diagnosis in the absence of the previous).

Primary endpoint is 30-day mortality, including in-hospital or out of hospital follow-up. However, we don’t expect any additional follow-up. So, data can be completed using the information available at the hospital at 30 days (accepting that this may miss some morbidity /mortality in the community).

Inclusion criteria for COVIDSURG CANCER study

Investigators can enrol patients with confirmed diagnoses of Colorectal, Oesophagogastric, Head & Neck, Lung, Hepatopancreatobiliary, Urological, Neurological, Gynaecological, Breast cancers and soft-tissue or Bone Sarcoma.
