PIX_HL7V3_Direct

The PIX_HL7V3_Direct project handles patient identity feeds and PIX queries for identifiers, which includes the following types of HL7 v3 messages:

• Patient Registry Record Added

• Patient Registry Record Revised

• Patient Registry Duplicates Resolved

• Patient Registry Get Identifiers Query

This project only contains one BPEL process, bpelPIXManager, that defines all of the processing logic for each message type. The BPEL process receives the incoming request and uses OnMessage activities to determine which type of processing to perform. For each message type, the process calls the Domain Lookup service to resolve domain names, and then calls the Master Index Facade EJB to perform the required operation. For patient record adds, the Master Index either adds a new record or updates an existing record depending on whether it finds a match in its database. For an identifiers query, the Master Index returns a list of patient identifiers associated with the given identifier if any are found.

The BPEL process also defines fault handling, generates the ACK/NACK responses, and generates the ATNA audit repository messages. The BPEL process includes mappings to the master index object structure. If you modify the master index object structure, the mapping in this process might also need to be updated.

This project includes the corresponding WSDL documents for each supported message type, and references the XML schema files to support HL7 v3 processing.
