|
| hl7:text
|
| ED | 0 … 1 | R | The <text> element if present points to the text describing the problem being recorded; including any dates, comments, et cetera. The <reference> contains a URI in value attribute. This URI points to the free text description of the problem in the document that is being described. | (IPS…nce) |

| | 1 … 1 | R | When used it shall refer to the narrative, typically #{label}-{generated-id}, e.g. #xxx-1 |
| hl7:statusCode
|
| CS | 1 … 1 | M | A clinical document normally records only those condition observation events that have been completed, not observations that are in any other state. Therefore, the <statusCode> shall always have code='completed'.

|
| cs | 1 … 1 | F | completed |
| hl7:effectiveTime
|
| IVL_TS | 1 … 1 | M | The effectiveTime, also referred to as the "biologically relevant time" is the time at which the observation holds for the patient. For a provider seeing a patient in the clinic today, observing a history of penicillin allergy that developed five years ago, the effectiveTime is five years ago. The effectiveTime of the Allergy - Intolerance Observation may give an indication of whether or not the underlying allergy/intolerance is resolved.
The <low> and <high> values should be no more precise than known, but as precise as possible. | (IPS…nce) |
| | hl7:low
|
| IVXB_TS | 1 … 1 | R | The effectiveTime/low (a.k.a. "onset date") asserts when the allergy/intolerance became biologically active.
| (IPS…nce) |
| | hl7:high
|
| IVXB_TS | 0 … 1 | C | The effectiveTime/high (a.k.a. "resolution date") asserts when the allergy/intolerance became biologically resolved.
If the date of resolution is not known, then effectiveTime/high will be present with a nullFlavor of "UNK".
| (IPS…nce) |
| | Constraint | If this condition is known to be resolved, then the effectiveTime/high would be present. |
| hl7:value
|
| CD.IPS CWE | 0 … 1 | C | While the value may be a coded or an uncoded string, the type is always a coded value (xsi:type='CD'). If uncoded, all attributes other than xsi:type='CD' must be absent and may contain a <reference> to the <originalText> in the narrative where the allergy is described. The coded form shall be used to indicate known absent conditions (e.g. NKA) or the nonavailability of infos about them; or in some cases the allergy to specific substances (e.g. allergy to nuts).
When the value is present in a coded form, no allergy agent is expected to be provided.

|
| hl7:participant
|
| | 0 … 1 | C | The substance that causes the allergy or intolerance should be specified in the <participant> structure.
This is the preferred way an allergy is supposed to be expressed.
However it is recognized that in some contexts a controlled vocabulary is used for describing the allergy to a substance; or for asserting known absence or unavailability of information.
In this case the <participant> structure shall be omitted.
The agent responsible for an allergy or adverse reaction is not always a manufactured material (for example, food allergies), nor is it necessarily consumed. The following constraints reflect limitations in the base CDA R2 specification, and should be used to represent any type of responsible agent, i.e., use playingEntity classCode = "MMAT" for all agents, manufactured or not.
