RGR: Pharmacy/treatment dose information
This page lists the structures and trigger events RGR defines, taken from the standard. The written commentary that theADT page carries has not been written for RGR.
Recognising RGR messages
RGR announces itself in MSH-9 like this:
RGR^RGR^RGR_RGR- MSH-9.1
RGRmessage code: what kind of message this is - MSH-9.2
RGRtrigger event: what happened in the real world - MSH-9.3
RGR_RGRmessage 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
RGR takes 1 structure.
RGR_RGR
Sent when one thing happens: RGR: RGR.
You must always send: MSH, MSA, QRD, ORC, RXG, 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 5 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..* | |
| RXG | R | 1..* | |
| RXR | R | 1..* | |
| RXC | O | 0..* | |
| 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. RGR defines 1.
