Allergies
Class ReactionObservation

Reaction: "A response to a substance, treatment, or other stimulus, such as an antigen-antibody reaction, an allergic reaction, or an adverse pharmacological reaction." - Mosby's Medical Dictionary
This class documents an Observation of an adverse physiological response attributed to the exposure of the Patient to the given substance. Note that the dates may be unspecified, such as when the Patient reports that she breaks out in hives when she eats peanuts.
"Details about each adverse reaction event linked to exposure to the identified substance." - HL7 FHIR, AllergyIntolerance.reaction

Attributes
«CS» Code certainty certainty

"Statement about the degree of clinical certainty that the Specific Substance was the cause of the Manifestation in this reaction event." - HL7 FHIR, AllergyIntolerance.event.certainty.
Note that the latest build of FHIR has removed this concept.

String description description

"Text description about the reaction as a whole, including details of the manifestation if required." - HL7 FHIR, AllergyIntolerance.reaction.description

String exposureRoute exposureRoute

"Identification of the route by which the subject was exposed to the substance." - HL7 FHIR, AllergyIntolerance.reaction.exposureRoute
Note that FHIR uses a code for this concept, but we modeled this as a string, because we currently do not foresee a need for this property. Should the partner agencies require the use of this property, a decision would need to be made regarding whether to use SNOMED codes as FHIR recommends, or FDA codes, which is required by Meaningful Use for other kinds of substance administrations.

Annotation note note

"Additional text about the adverse reaction event not captured in other fields." - HL7 FHIR, AllergyIntolerance.reaction.note

"Record of the date and/or time of the onset of the Reaction." - HL7 FHIR, AllergyIntolerance.reaction.onset
"Date of reaction to the immunization." - HL7 FHIR, Immunization.reaction.date

«CS» Code reaction reaction

Indicates the adverse physiological response which is suspected to have been caused by an exposure to the given substance (i.e., the reactant).
"Identifies the specific allergic reaction that was documented." - HL7 Version 2.8, AL1-5 and IAM-5
"Clinical symptoms and/or signs that are observed or associated with the adverse reaction event." - HL7 FHIR, AllergyIntolerance.reaction.manifestation

"Clinical assessment of the severity of the reaction event as a whole, potentially considering multiple different manifestations." - HL7 FHIR, AllergyIntolerance.reaction.severity
