D.4.0 U.S. Data Access Framework (DAF) AllergyIntolerance Profile

D.4.0.1 Scope and Usage

This profile sets expectations for use of the AllergyIntolerance resource to record allergies/adverse events associated with a patient within the Data Access Framework (DAF) Implementation Guide. This profile identifies which core elements, extensions, vocabularies and value sets must be Supported by DAF actors. For the definition of Supported please refer to DAF FHIR IG. The data elements identified by the profile are based on ONC 2014 Edition S&CC and DAF use cases. The mappings between the ONC 2014 Edition S&CC data elements and DAF data elements are captured in the table below, where the first column identifies the ONC 2014 Edition S&CC data element name, the second column maps the ONC 2014 Edition S&CC data elements to DAF data elements which are derived from ONC 2014 Edition S&CC standards and DAF use cases and lastly the third column identifies the mapping to FHIR resources and attributes.

D.4.0.2 Meaningful Use Data Element Mapping

The DAF AllergyIntolerance profile mapping to Meaningful Use data elements and FHIR Resources are as shown below.


Meaningful Use Data Element Name Mapping to Priority DAF Data Elements FHIR Resource Mapping
Medication Allergies
Allergy Substance AllergyIntolerance.substance
Allergy/Adverse Event Type AllergyIntolerance.category
Allergy Status AllergyIntolerance.status
Allergy Reaction AllergyIntolerance.reaction.manifestation
Allergy Severity AllergyIntolerance.reaction.severity
Allergy Intolerance Reaction Duration AllergyIntolerance.reaction.duration
Allergy Intolerance Occurrence Date AllergyIntolerance.reaction.onset

D.4.0.3 Boundaries and Relationships

This profile relies on the following other profiles:

  • DAFPatient which defines DAF Patient profile is used by DAFAllergyIntolerance profile to refer to patients.
  • FHIR Extensibility defines how extensions can be applied to FHIR resources and data types. Specifically the data-absent-reason extension can be used to code data elements with missing information when appropriate. See DAF FHIR IG for additional guidance.

D.4.0.4 Content

Profiles:
DAF-AllergyIntoleranceDefines constraints and extensions on the AllergyIntolerance resource for use in querying and retrieving allergy information.

D.4.0.4.1 Search Parameters

The full list of supported search parameters are can be accessed at DAF Requestor conformance expectations and DAF Responder conformance expectations.

D.4.0.4.2 Example Usage Scenarios

The following are example usage scenarios for the DAF AllergyIntolerance profile:

  • Query for allergies belonging to a Patient
  • Query for all patients who have had a specific allergy category
  • Query for allergies experienced during a time period
  • Query for allergies for a patient for a specific category
  • Query for allergies based on reaction and severity

D.4.0.4.3 Profile specific implementation guidance

Implementers need to be mindful of the following during their implementation

    Representing No Known Allergies: No Known Allergies will be represented using the DAFAllergyList profile with no entries and a valid code in the List's emptyReason element.

    See DAF FHIR IG for implementation guidance common to all profiles.
