CRM: Clinical study registration message

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

Recognising CRM messages

CRM announces itself in MSH-9 like this:

MSH-9CRM^C01^CRM_C01
  1. MSH-9.1CRMmessage code: what kind of message this is
  2. MSH-9.2C01trigger event: what happened in the real world
  3. MSH-9.3CRM_C01message 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

CRM takes 1 structure.

CRM_C01

No trigger event in the standard names this structure.

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

SegmentNameOPTCardinality
MSHR1..1
SFTO0..*
PATIENTa group of 4 segments, repeated togetherR1..*
PIDR1..1
PV1O0..1
CSRR1..1
CSPO0..*

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: PATIENT.

Trigger events

The trigger event is the real-world thing that made the message get sent. CRM defines 0.
