| 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) |
| | | | hl7ips-dataelement-187 | Onset date | CEN/TC 251 prEN 17269 |
|
| | 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) |
| | | | hl7ips-dataelement-188 | End Date | CEN/TC 251 prEN 17269 |
|
| | Constraint | If this condition is known to be resolved, then the effectiveTime/high would be present. |
| Choice | 0 … 1 | | The coded form of the observation value can be used : - either to indicate known absent conditions (e.g. NKA) or the nonavailability of information;
- or to provide pre-coordinated codes describing the propensity to specific substances (e.g. allergy to nuts).
The choice reflects these options. |

| 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. | (IPS...nce) |
