RRA: Pharmacy/treatment administration acknowledgment message
This page lists the structures and trigger events RRA defines, taken from the standard. The written commentary that theADT page carries has not been written for RRA.
Recognising RRA messages
RRA announces itself in MSH-9 like this:
RRA^O18^RRA_O18- MSH-9.1
RRAmessage code: what kind of message this is - MSH-9.2
O18trigger event: what happened in the real world - MSH-9.3
RRA_O18message 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
RRA takes 1 structure.
RRA_O18
Sent when one thing happens: O18: O18.
You must always send: MSH, MSA. Everything else is optional, or required only inside a group you chose to send.
| Segment | Name | OPT | Cardinality |
|---|---|---|---|
| MSH | R | 1..1 | |
| MSA | R | 1..1 | |
| ERR | O | 0..* | |
| SFT | O | 0..* | |
| NTE | O | 0..* | |
| RESPONSE | a group of 2 segments, repeated together | O | 0..1 |
| PATIENTin RESPONSE | a group of 2 segments, repeated together | O | 0..1 |
| PIDin PATIENT | R | 1..1 | |
| NTEin PATIENT | O | 0..* | |
| ORDERin RESPONSE | a group of 3 segments, repeated together | R | 1..* |
| ORCin ORDER | R | 1..1 | |
| TIMINGin ORDER | a group of 2 segments, repeated together | O | 0..* |
| TQ1in TIMING | R | 1..1 | |
| TQ2in TIMING | O | 0..* | |
| ADMINISTRATIONin ORDER | a group of 2 segments, repeated together | O | 0..1 |
| RXAin ADMINISTRATION | R | 1..* | |
| RXRin ADMINISTRATION | R | 1..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 5 such groups: RESPONSE, PATIENT, ORDER, TIMING, ADMINISTRATION.
Trigger events
