Feed HL7 patient updates to other systems

Goal: patient updates (ADT) from the EHR or RIS reach the PACS and an AI vendor, each edited the way it needs, in order, with nothing lost when a system is down.

1. Receive HL7

Turn on the HL7 port (Settings › HL7 and modality worklist), list the sender’s address, and point the EHR’s or interface engine’s ADT feed at the router, as in Build a modality worklist.

2. The destinations

Configuration › HL7 routing › Add HL7 destination, for each system: name, host and port, MLLP over TLS if it supports it, and When it refuses a message (AE): Stop until someone retries or skips it (the default, which keeps patient records in order), or put such messages aside and send the next.

3. The routes

ADT to PACS: Message types ADT^A0*, ADT^A40, destination PACS, with edits:

Path	Action	Value
MSH-5	Set	PACS
MSH-6	Set	RADIOLOGY

ADT to AI vendor: Message types ADT^A08, a condition PV1-2 Equals O (outpatients only), destination AI vendor, with edits that remove what the vendor must not have:

Path	Action	Value
PID-11	Clear
PID-13	Clear
NK1	Remove segment

4. Test it

Paste a real (or sample) message in Configuration › HL7 routing › Test and run it: you see which routes take it, and the exact copy each would send.

Check it

History › HL7 messages shows each message received, and its state at each destination. If a destination refuses one, its queue stops (with an alert): open the message, fix the cause, then Retry now, or Skip it.
