RAR: Pharmacy/treatment administration information
This page lists the structures and trigger events RAR defines, taken from the standard. The written commentary that theADT page carries has not been written for RAR.
Recognising RAR messages
RAR announces itself in MSH-9 like this:
RAR^RAR^RAR_RAR- MSH-9.1
RARmessage code: what kind of message this is - MSH-9.2
RARtrigger event: what happened in the real world - MSH-9.3
RAR_RARmessage 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
RAR takes 1 structure.
RAR_RAR
Sent when one thing happens: RAR: RAR.
You must always send: MSH, MSA, QRD, ORC, RXA, RXR. 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..* | |
| DEFINITION | a group of 4 segments, repeated together | R | 1..* |
| QRD | R | 1..1 | |
| QRF | O | 0..1 | |
| PATIENT | a group of 2 segments, repeated together | O | 0..1 |
| PIDin PATIENT | R | 1..1 | |
| NTEin PATIENT | O | 0..* | |
| ORDER | a group of 4 segments, repeated together | R | 1..* |
| ORC | R | 1..1 | |
| ENCODING | a group of 3 segments, repeated together | O | 0..1 |
| RXEin ENCODING | R | 1..1 | |
| RXRin ENCODING | R | 1..* | |
| RXCin ENCODING | O | 0..* | |
| RXA | R | 1..* | |
| RXR | R | 1..1 | |
| DSC | O | 0..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 4 such groups: DEFINITION, PATIENT, ORDER, ENCODING.
Trigger events
The trigger event is the real-world thing that made the message get sent. RAR defines 1.
| Event | Name | Structure |
