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.
