2.4 Reusable Transaction Catalog

The MAP RTC identifies reusable Shared Activities and their defining specifications. TX1–TX8 are local labels for navigation within this guide; the applicable transaction-type code identifies the Shared Activity for interoperable exchange. The maternal-health workflows compose these transactions rather than redefine each notification or document exchange. Chapter 3 establishes the common requirements and Transaction Definition structure.

The defining specifications below establish the organization of reusable transaction requirements. This guide defines TX3 and supplies maternal-health requirements for the reused transactions. TX6 is a non-Direct query placeholder. Apply the defining Transaction Definition together with the maternal-health requirements in this guide.

TX	Shared Activity and defining specification	Primary or relevant information objects	Maternal-health application
TX1	send-outpatient-visit-notification Event Notifications via Direct	Outpatient visit notification (HL7 V2)	Send notification that an outpatient maternal-health encounter has occurred or completed, in human-readable and machine-processable form.
TX2	send-admission-notification Event Notifications via Direct	Registration or admission notification (HL7 V2)	Send notification of a registration or admission event relevant to the maternal-health use case, in human-readable and machine-processable form.
TX3	send-birth-notification Care Coordination for Maternal Health – Birth	Maternal Health Birth Notification (CDA)	Communicate newborn birth information to the mother’s care team through the specialized maternal-health birth notification document.
TX4	send-discharge-notification Event Notifications via Direct	Hospital or ED discharge notification (HL7 V2)	Send notification of a discharge event relevant to the maternal-health use case, in human-readable and machine-processable form.
TX5	send-documents Send Documents via Direct	Primary CDA document and permitted additional documents	Send one or more maternal-health documents to support pregnancy notification and risk assessment, referral/orders, antepartum, birth, postpartum, and continuity-of-care information sharing.
TX6	query-for-documents Care Coordination for Maternal Health – Birth — placeholder	Documents discovered and retrieved through query protocols	Represent document request and retrieval exchanges outside Direct; not a specified Direct transaction.
TX7	send-patient-update Update Patient Matching Information via Direct	Patient update A08, or Change List with an updated Patient resource	Send updated patient information that may affect patient matching for parties with which information has previously been shared.
TX8	send-workflow-status Workflow Status via Direct	Originating SubmissionSet/List information object; report Task and Provenance accompany it	Report acceptance or rejection of the entire originating structured payload into its intended workflow. Acceptance does not establish subsequent processing or service completion.

TX1, TX2, TX3, TX4, TX5, TX7, and TX8 are in scope. TX6 remains a conceptual query placeholder. TX1, TX2, and TX4 are ADT event notifications; TX3 is a specialized document exchange. Additional clinical documents do not accompany TX1, TX2, or TX4. Required Tasks, metadata, human-readable copies, and permitted Provenance remain part of their structured payloads.
