This template reflects an ongoing concern on behalf of the person that placed the allergy on a patient’s allergy list.
A concern may refer to one or more allergies or intolerances.
There are different kinds of status that could be related to an allergy, or more in general to a condition:
- The status of the concern (active, inactive,..)
- The status of the condition (e.g. active, inactive, resolved,..)
- The confirmation status [clinical workflow status, certainty] (e.g. confirmed, likely, unlikely,…)
Not all of them can be represented in a CDA using the statusCode elements of the concern (ACT) and observation (condition).
The statusCode within the Patient Summary is as long as it is of concern to the provider (i.e., as long as the condition, whether active or resolved, is of ongoing concern and interest to the provider), the statusCode is “active”.
When the underlying conditions are no longer of concern the information is the statusCode would be “completed” and those entries are not foreseen in the Patient Summary.
The effectiveTime/low of the Allergy Concern Act asserts when the concern became active. This equates to the time the concern was authored in the patient's chart.
The effectiveTime/high asserts when the concern became inactive, and it is present if the statusCode of the concern act is "completed", normally not foreseen in the Patient Summary.
