Background: Studies that perform clinical data capture on using Brain-CODE’s REDCap instance for data collection typically have collect all data collected within a single REDCap project. For multi-site studies, REDCap’s Data Access Group (DAG) feature can be implemented and Data Access Groups created for each site in the study, to ensure that access to a site’s study data can be restricted to the site’s members. Researchers that are limited to accessing data at a single site, will be added as a member to that site’s is used to ensure each site has a DAG that limits their users' access only to the appropriate site’s records.
If a REDCap user is assigned to a single Data Access Group, they will only be able to view records in their DAG and any new records they create will automatically be assigned to that DAG.
If a REDCap user requires access to multiple Data Access Groups, the DAG Switcher feature will be implemented. As users can only be assigned one DAG at a time, the DAG Switcher allows users to switch their current DAG so that it can only be viewed and edited by other site membersthey can create or access records from any of the DAGs to which they have been assigned.
If a user is granted access to more than one Data Access Group within a REDCap Project/Study any new records they create within the REDCap project requires access across all Data Access Groups, no DAG will be assigned and they will be able to view all records in the project. Without an assigned DAG, any new records created will not have a DAG assigned automatically assigned to them, and will instead need to be manually assigned to the correct DAG corresponding to their Study site to be visible to DAG-assigned users.

uDCD8 How to Switch Data Access Groups in REDCap
If you are assigned to multiple Data Access Groups within a REDCap project, you will need to switch your DAG before entering, updating, or viewing data not from your current DAG / site.
Navigate to your REDCap project.
If you have access to multiple DAGs you will see your current DAG listed at the top of the page.
Click Switch, select the Data Access Group you would like to switch to, and click Switch.
When you navigate to the Record Status Dashboard, you will now only see records for the site you have switched to. Any new records you create will be in the new DAG and will only be accessible by all team members who have access to that DAG.

Before creating a new record in REDCap, ensure that your current DAG indicates the correct site for the participant. |
