HL7 interface scoping: describe the message journey

Illustrative situation

A supplier proposes an HL7 connection but the receiving team has not agreed which events need to be exchanged.

The decision

Describe the operational events, sending and receiving systems and expected outcome. Ask the implementation team to identify the applicable message specifications and local requirements.

Rehearse this before accepting the change

Walk through a fictional event from source action to receiving-system result.

Use fictional examples and an authorised test environment. Record what happened, the evidence you inspected and any issue that still needs a responsible owner.

Choose a useful measure

Count events lacking a defined receiving outcome.

Agree the definition and baseline with the team doing the work. Review the result over a comparable period and note other changes that could affect it.

Healthcare data integration connecting two applications through a field-mapping board.
Agree what each field means and which system owns it.
Healthcare data validation separating matched records from an exception tray.
Make rejected or uncertain records visible for review.
Healthcare integration recovery with queued records, a retry route and a receipt check.
Plan recovery and confirm the receiving result.

Your planning worksheet

Use these checks to prepare a discussion with your team or supplier. Tick a check when you have recorded the decision or evidence, rather than when a feature has simply been promised.
