(CCD) Any problem or allergy observation may reference a problem status observation.
This structure is included in the target observation using the <entryRelationship>
element defined in the CDA Schema. The clinical status observation records information
about the current status of the problem or allergy, for example, whether it is active,
in remission, resolved, et cetera. The example below shows the recording of clinical
status of a condition or allergy, and is used as the context for the following sections.
This CCD models a problem status observation as a separate observation from the problem,
allergy or medication observation. While this model is different from work presently
underway by various organizations (i.e., SNOMED, HL7, TermInfo), it is not wholly
incompatible with that work. In that work, qualifiers may be used to identify problem
status in the coded condition observation, and a separate clinical status observation
is no longer necessary. The use of qualifiers in the problem observation is not precluded
by this specification or by CCD. However, to support semantic
interoperability between EMR systems using different vocabularies, this specification
does require that problem status information also be provided in a separate observation.
This ensures that all EMR systems have equal access to the information, regardless
of the vocabularies they support.

The <text> element is required and 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.
