RQC: Request clinical information

This page lists the structures and trigger events RQC defines, taken from the standard. The written commentary that theADT page carries has not been written for RQC.

Recognising RQC messages

RQC announces itself in MSH-9 like this:

MSH-9RQC^I05^RQC_I05
  1. MSH-9.1RQCmessage code: what kind of message this is
  2. MSH-9.2I05trigger event: what happened in the real world: request for patient clinical information
  3. MSH-9.3RQC_I05message structure: which segments to expect, and in what order

How to use these specifications explains MSH-9 in full, with a worked example.

Message structures

RQC takes 1 structure.

RQC_I05: Request For Patient Clinical Information

2 different trigger events send this structure:

The segments below are the same for all 2. HL7 varies the meaning, not the shape: there is no separate RQC_I06 layout. What changes is MSH-9, which tells the receiver which of the 2 happened and therefore what to do with the message.

You must always send: MSH, QRD, PRD, PID. Everything else is optional, or required only inside a group you chose to send.

SegmentNameOPTCardinality

PROVIDERa group of 2 segments, repeated togetherR1..*
PRDR1..1

R inside a group means required of that group. Send the group and you must include that segment; leave the group out and it never appears. This structure has 1 such group: PROVIDER.

Trigger events

The trigger event is the real-world thing that made the message get sent. RQC defines 2.
