Description

This template reflects a discrete observation about a patient's allergy or intolerance.

Because it is a discrete observation, it will have a statusCode of "completed".

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 gives an indication of whether or not the underlying allergy/intolerance is resolved. If known to be resolved, then an effectiveTime/high would be present.

If the date of resolution is not known, then effectiveTime/high will be present with a nullFlavor of "UNK".
It is recommended that the agent responsible for an allergy or adverse reaction would be used for describing the allergy, however the possibility that pre-coordinate codes (e.g. "allergy to nuts") will be used has been here also considered.
The agent responsible for an allergy or adverse reaction it is not always a manufactured material (for example, food allergies), nor is it necessarily consumed; however the playingEntity classCode = "MMAT" for all agents, manufactured or not is expected to be used. This choice depends on thecharacteristics of the base CDA R2 specification.

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:value[2]

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.
