Working With the EDM for Sun Master Patient Index

AuxId Objects

AuxId objects store a patient’s auxiliary IDs in a system record or SBR. Auxiliary IDs are identifiers assigned to a patient that are not necessarily unique to each patient. For example, they can be used to store a credit card number for a joint credit card, an account number for a joint checking account, or an insurance policy number for a policy that covers all members of a family. Each system record or SBR can store multiple auxiliary IDs. By default, all auxiliary IDs from each system record in a patient profile are included in the SBR. If two system records contain identical auxiliary ID objects, then only one of those objects is stored in the SBR.
