We need your help

We need your help in filling the ERACODA database. If one (or more) of your patients is diagnosed with COVID-19, please contact us by e-mail at:

You will then be added as a user to the data platform REDCap within one working day. When your account is ready, you will receive an automatically generated e-mail including your login details and data entry instructions

If there is a similar, national initiative for data collection in your country, we would like to ask you also to join ERACODA.


Because this initiative is meant to analyze and improve patient care, and is purely observational, the Institutional review Board (IRB) of the University Medical Center Groningen in The Netherlands waived the approval in the context of the Medical Research Involving Human Subjects Act and confirmed this in writing. It may be, however, that in your institution the situation is different. In case of doubt, please check your local IRB. When needed, we can be of help with obtaining IRB approval.



The following documents (in English) are available that can be adapted to meet your local requirements:

         Template letter for IRB approval


          Template Study Protocol


          Research data management plan


​​          Template Patient information form opt-in


          Template Signature page opt-in


          Template Patient information form opt-out


          Template Signature page opt-out


​          Template Data Transfer Agreement
