        v: Element `AdverseEvent.text` is mapped to FHIR R4 element `AdverseEvent.text` as `Equivalent`. Contained resources do not have a narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.

        v: Element `AdverseEvent.contained` is mapped to FHIR R4 element `AdverseEvent.contained` as `Equivalent`. This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags in their meta elements, but SHALL NOT have security labels.

      comment:
        v: Element `AdverseEvent.identifier` is mapped to FHIR R4 element `AdverseEvent.identifier` as `SourceIsBroaderThanTarget`. This is a business identifier, not a resource identifier (see [discussion](https://hl7.org/fhir/resource.htm#identifiers)). It is best practice for the identifier to only appear on a single resource instance, however business practices may occasionally dictate that multiple resource instances with the same identifier can exist - possibly even with different resource types. For example, multiple Patient and a Person resource instance might share the same social insurance number.

        v: Element `AdverseEvent.actuality` is mapped to FHIR R4 element `AdverseEvent.actuality` as `Equivalent`. AllergyIntolerance should be used for the initial capture or recording of the individual's propensity to an adverse reaction to a substance. If an AllergyIntolerance does not exist, then an adverse reaction should be recorded as an AllergyIntolerance. If an AllergyIntolerance does exist and the substance was given, then an adverse reaction should be recorded as an AdverseEvent due to the aberrant workflow.

    v: Element `AdverseEvent.encounter` is mapped to FHIR R4 element `AdverseEvent.encounter` as `Equivalent`. This will typically be the encounter the event occurred within, but some activities may be initiated prior to or after the official completion of an encounter but still be tied to the context of the encounter. For example, if a medication administration was considered an adverse event because it resulted in a rash, then the encounter when the medication administration was given is the associated encounter. If the patient reports the AdverseEvent during a second encounter, that second encounter is not the associated encounter.

Using an example, a rash can have an AdverseEvent.resultingEffect.severity = severe, yet an AdverseEvent.seriousness = non-serious. Alternatively, a medication given with the wrong dose (chemotherapy given with too low of a dose) can have an AdverseEvent.resultingEffect.severity = mild, yet an adverseEvent.seriousness = serious. Another example would be a beta blocker clinical trial where patients with asthma should be excluded, yet a patient with asthma was included and had an asthmatic episode where AdverseEvent.resultingEffect.severity = mild, yet an adverseEvent.seriousness = serious.

      v: Element `AdverseEvent.suspectEntity.instance[x]` is mapped to FHIR R4 element `AdverseEvent.suspectEntity.instance` as `SourceIsBroaderThanTarget`. The mappings for `AdverseEvent.suspectEntity.instance[x]` do not cover the following types: CodeableConcept. The standard extension `alternate-reference` has been mapped as PART of the representation of FHIR R5 element `AdverseEvent.suspectEntity.instance[x]` with unmapped reference targets: BiologicallyDerivedProduct, ResearchStudy.

      v: Element `AdverseEvent.contributingFactor` has a context of AdverseEvent based on following the parent source element upwards and mapping to `AdverseEvent`. Element `AdverseEvent.contributingFactor` has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element).
