PIX - Patient Identifier Cross Reference
This transaction involves a request by the Patient Identifier Cross-reference Consumer Actor for a list of patient identifiers that correspond to a primary (definitional) patient identifier known by the consumer. The request is received by the Patient Identifier Cross-reference Manager. The Patient Identifier Cross-reference Manager immediately processes the request and returns a response in the form of a list of corresponding patient identifiers (active and inactive).
This transaction is equivalent to the Pan-Canadian HL7v3 Find Associated Identifiers interaction.
Query by one of these primary IDs:
- PCR Enterprise ID (EID) aka Enterprise Client ID (ECID)
- Health Card Number (HCN)
- Corporate ID (CORPID) for corporate model hospitals
- Medical Record Number (MRN) for standard model hospitals
A source OID (ID Issuer) & corresponding ID value must be provided in the request.
For example, for PCR EID:
OID (ID Issuer) = 2.16.840.1.1138126.96.36.199 (eHealth Ontario PCR Enterprise Identifier (EID))
ID = 123456
Based on exact matching the primary ID for a given active or inactive member record, pull the entity view for that single client. Returns all identifiers (i.e. both active & inactive (i.e. merged, deleted)) for the given client.
Returns the following business attributes (where they exist, depending on PCR data density for the given client):
- PCR EID
- Ontario Health Card Number
- Non-Ontario (Out-of-Province) Health Card Number(s)
- Corporate ID(s)
- Medical Record Number(s)
