Resource AdverseReaction - Content4.1
Specific reactions to a substance.
The resource name as it appears in a RESTful URL is [root]/adversereaction/
Adverse Reaction resources are used to provide information about specific reactions to a substance. These are normally associated with an AllergyIntolerance resource, but can be reported on their own when no assumption of further reactions is being made, or when specific events are being described.
An Adverse Reaction normally has a set of signs or symptoms that are reported in the Symptom class. However, it is possible to convey that an adverse reaction occurred without knowing the specific signs or symptoms that occurred, e.g. Some unknown reaction occurred.Similarly, it is possible to convey that an adverse reaction with a set of symptoms occurred but not indicate the substance if it is not known. e.g. A rash occurred for some unknown reason.
The Exposure class is used to indicate a set of exposures that preceded the reaction. There is no assertion of causality, purely a statement of timing. Each exposure can indicate a substance that might be different from the reaction if needed.

Terminology Bindings 4.1.1.1
Notes:4.1.2
- Vocabulary Bindings
- The vocabulary bindings are tentative at this point. Further guidance is needed on whether the current bindings are reasonable.
- ExposureType is currently a code, but if a suitable value set was used, it could (should?) be changed to a CodeableConcept.
