On occasion your team may inadvertently create a duplicate participant in a Ripple registry. Having duplicates can potentially cause issues for both your study (data integrity and management purposes) and in how Ripple functions.
Reminder: A duplicate is defined as a set of participants who have an identical Global ID and/or an identical First Name/Last Name/Birthdate.
If you received an error message indicating a set of duplicates may exist in your registry, of if you identify a set of duplicates through your work, it is best practice to merge these participants into one profile so that it does not cause issues with your study. To identify any potential duplicates, those team members with registry access can navigate to your registry and click the potential duplicate button highlighted below:
Once clicked, the registry will display sets of participants that appear to be duplicates:
From here you will be able to manually combine these participants into one participant to have all data in one profile. Note: Any set of potential duplicates will appear in this search including sets of two participants or potentially three or more depending on how your duplicates were created.
