The base topic for conditions, allergies, adverse events, etc. These are things that are asserted to exist or not. The Value is interpreted in the context of the class; for an AdverseSensitivityToSubstance, the value is the substance; for a ConditionPresenceStatement, the Value represents the type of condition found.

CIMI Alignment: In CIMI V0.0.4, this class was called Assertion, but CIMI recently decided to change the name to AssertionTopic, as anticipated here. In CIMI V0.0.4, Assertion defines three attributes: dateAsserted, verificationStatus, and findingMethod. VerificationStatus more properly only applies in the PresenceContext context, and can be found there. FindingMethod more properly belongs in FindingTopic, and can be found there.

The concept representing the finding or action that is the topic of the statement.

For action topics, the TopicCode represents the action being described. For findings, the TopicCode represents the 'question' or property being investigated. For evaluation result findings, the TopicCode contains a concept for an observable entity, such as systolic blood pressure. For assertion findings, the TopicCode contains a code representing the condition, allergy, or other item being asserted. In all cases, the TopicCode describes the topic independent of the context of the action or the finding.

CIMI Alignment: TopicCode is the new CIMI name for the attribute formerly called 'key' in CIMI V0.0.4.

The technique used to create the finding; for example, the specific imaging technique, lab test code, or assessment vehicle.

CIMI Alignment: In CIMI V0.0.4, this attribute was called 'method'. The value set binding reflects CIMI's preference for LOINC codes.

A clinical interpretation of a finding.

CIMI Alignment: The value set binding has been chosen to align with FHIR. (Note: it is not clear if Interpretation belongs in FindingTopic, rather than a context class, but that is how CIMI has modeled it.)
