Question: Alerts in v2 messages
Jun 6, 2013Question:
I have a question about which segment in the HL7 v2.3 Patient Admin messages; Administrative and Clinical alert information can be found? i.e Isolation. MRSA.
I understand some of the information may come through in the AL1 segment and the PV2 segment. Is there a segment for Alerts?
Answer:
There is no specific v2 segment for patient alerts. To the degree that allergies count as alerts, alert information may be found in the AL1 segment, and also, there is PV2-41 which contains some simple coded information that counts as alerts:
| Value | Description |
| A | Aggressive |
| B | Blind |
| C | Confused |
| D | Deaf |
| I | On IV |
| N | “No-code” (i.e. Do not resuscitate) |
| P | Paraplegic |
| O | Other |
| U | Unknown |
There is no general specific segment for alerts. They should be represented as patient observations in the OBX segments found after PV1 in the ADT messages:
There doesn’t seem to be any suitable LOINC codes for this use, so you’d have to make up your own codes.
p.s. This is the secdon
