When you perform a patient profile merge, you are working with two patient profiles. The non-surviving profile is the profile that is not retained after the merge. The surviving profile is retained after the merge. During a patient profile merge, the system records in the non-surviving profile are transferred to the surviving profile, and the non-surviving profile is given a status of “Merged”. The SBR for the surviving patient profile is recalculated based on the existing system records for that profile along with the newly merged system records. The EUID of the surviving profile is always retained. The information that is discarded during a merge is stored in the transaction table, making it possible to restore the profiles to their original EUIDs if they were merged in error.
