Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).

    v: Element `AllergyIntolerance.substance` is mapped to FHIR R5 element `AllergyIntolerance.code` as `Equivalent`. It is strongly recommended that the substance be coded with a terminology, where possible. For example, some terminologies used include RxNorm, SNOMED CT, DM+D, NDFRT, ICD-9, IDC-10, UNI, ATC and CPT. Plain text should only be used if there is no appropriate terminology available. Additional details about a substance can be specified in the text.

The mappings for `AllergyIntolerance.status` do not allow expression of the necessary codes, per the bindings on the source and target. Decision support would typically raise alerts for 'Unconfirmed', 'Confirmed', and 'Resolved' and ignore a 'Refuted' reaction. In particular, 'Refuted' may be useful for reconciliation of the Adverse Reaction List. Some implementations may choose to make this field mandatory.

  comment:
    v: Element `AllergyIntolerance.criticality` is mapped to FHIR R5 element `AllergyIntolerance.criticality` as `Equivalent`. The default criticality value for any propensity to an adverse reaction should be 'Low Risk', indicating at the very least a relative contraindication to deliberate or voluntary exposure to the Substance. 'High Risk' is flagged if the clinician has identified a propensity for a more serious or potentially life-threatening reaction, such as anaphylaxis, and implies an absolute contraindication to deliberate or voluntary exposure to the substance. If this element is missing, the criticality is unknown (though it may be known elsewhere).

  comment:
    v: Element `AllergyIntolerance.type` is mapped to FHIR R5 element `AllergyIntolerance.type` as `SourceIsNarrowerThanTarget`. Allergic (typically immune-mediated) reactions have been traditionally regarded as an indicator for potential escalation to significant future risk. Contemporary knowledge suggests that some reactions previously thought to be immune-mediated are, in fact, non-immune, but in some cases can still pose a life threatening risk. It is acknowledged that many clinicians may not be in a position to distinguish the mechanism of a particular reaction. Often the term "allergy" is used rather generically and may overlap with the use of "intolerance" - in practice the boundaries between these two concepts may not be well-defined or understood. This data element is included nevertheless, because many legacy systems have captured this attribute. Immunologic testing may provide supporting evidence for the basis of the reaction and the causative substance, but no tests are 100% sensitive or specific for sensitivity to a particular substance. If, as is commonly the case, it is unclear whether the reaction is due to an allergy or an intolerance, then the type element should be omitted from the resource.

    v: Element `AllergyIntolerance.category` is mapped to FHIR R5 element `AllergyIntolerance.category` as `RelatedTo`. This data element has been included because it is currently being captured in some clinical systems. This data can be derived from the Substance where coding systems are used, and is effectively redundant in that situation.

For example: including reason for flagging a seriousness of 'High Risk'; and instructions related to future exposure or administration of the Substance, such as administration within an Intensive Care Unit or under corticosteroid cover. The notes should be related to an allergy or intolerance as a condition in general and not related to any particular episode of it. For episode notes and descriptions, use AllergyIntolerance.event.description and AllergyIntolerance.event.notes.

  comment:
    v: Element `AllergyIntolerance.reaction.substance` is mapped to FHIR R5 element `AllergyIntolerance.reaction.substance` as `Equivalent`. Coding of the specific substance with a terminology capable of triggering decision support should be used wherever possible. The substance field allows for the use of a specific substance or a group or class of substances, for example "Penicillins". The specific substance field could be used for Amoxycillin. Duplication is acceptable when a specific substance has been recorded in the 'substance' field.

    v: Element `AllergyIntolerance.reaction.manifestation` is mapped to FHIR R5 element `AllergyIntolerance.reaction.manifestation` as `SourceIsNarrowerThanTarget`. Manifestation can be expressed as a single word, phrase or brief description. For example: nausea, rash or no reaction. It is preferable that manifestation should be coded with a terminology, where possible. The values entered here may be used to display on an application screen as part of a list of adverse reactions, as recommended in the UK NHS CUI guidelines. Terminologies commonly used include, but are not limited to, SNOMED CT or ICD10.

      v: Element `AllergyIntolerance.recordedDate` has a context of AllergyIntolerance based on following the parent source element upwards and mapping to `AllergyIntolerance`. Element `AllergyIntolerance.recordedDate` has no mapping targets in FHIR R5. Typically, this is because the element has been added (is a new element).

    comment:
      v: Element `AllergyIntolerance.status` is mapped to FHIR R5 element `AllergyIntolerance.clinicalStatus` as `RelatedTo`. Element `AllergyIntolerance.status` is mapped to FHIR R5 element `AllergyIntolerance.verificationStatus` as `RelatedTo`. The mappings for `AllergyIntolerance.status` do not allow expression of the necessary codes, per the bindings on the source and target. Decision support would typically raise alerts for 'Unconfirmed', 'Confirmed', and 'Resolved' and ignore a 'Refuted' reaction. In particular, 'Refuted' may be useful for reconciliation of the Adverse Reaction List. Some implementations may choose to make this field mandatory.

    comment:
      v: Element `AllergyIntolerance.type` is mapped to FHIR R5 element `AllergyIntolerance.type` as `SourceIsNarrowerThanTarget`. Allergic (typically immune-mediated) reactions have been traditionally regarded as an indicator for potential escalation to significant future risk. Contemporary knowledge suggests that some reactions previously thought to be immune-mediated are, in fact, non-immune, but in some cases can still pose a life threatening risk. It is acknowledged that many clinicians may not be in a position to distinguish the mechanism of a particular reaction. Often the term "allergy" is used rather generically and may overlap with the use of "intolerance" - in practice the boundaries between these two concepts may not be well-defined or understood. This data element is included nevertheless, because many legacy systems have captured this attribute. Immunologic testing may provide supporting evidence for the basis of the reaction and the causative substance, but no tests are 100% sensitive or specific for sensitivity to a particular substance. If, as is commonly the case, it is unclear whether the reaction is due to an allergy or an intolerance, then the type element should be omitted from the resource.

      v: Element `AllergyIntolerance.category` is mapped to FHIR R5 element `AllergyIntolerance.category` as `RelatedTo`. This data element has been included because it is currently being captured in some clinical systems. This data can be derived from the Substance where coding systems are used, and is effectively redundant in that situation.

      v: Element `AllergyIntolerance.note` is mapped to FHIR R5 element `AllergyIntolerance.note` as `RelatedTo`. The mappings for `AllergyIntolerance.note` do not cover the following types: Annotation. The mappings for `AllergyIntolerance.note` do not cover the following types based on type expansion: author[x], text, time. For example: including reason for flagging a seriousness of 'High Risk'; and instructions related to future exposure or administration of the Substance, such as administration within an Intensive Care Unit or under corticosteroid cover. The notes should be related to an allergy or intolerance as a condition in general and not related to any particular episode of it. For episode notes and descriptions, use AllergyIntolerance.event.description and AllergyIntolerance.event.notes.

Use this field to record information indirectly related to a particular event and not captured in the description. For example: Clinical records are no longer available, recorded based on information provided to the patient by her mother and her mother is deceased.
