US Quality Core Implementation Guide, published by HL7 International / Clinical Quality Information. This guide is not an authorized publication; it is the continuous build for version 1.0.0-ballot built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/fhir-us-quality-core/ and changes regularly. See the Directory of published versions

Resource Profile: US Quality Core AllergyIntolerance

Official URL: http://hl7.org/fhir/us/quality-core/StructureDefinition/us-quality-core-allergyintolerance Version: 1.0.0-ballot
Standards status: Trial-use Maturity Level: 4 Computable Name: USQualityCoreAllergyIntolerance
Other Identifiers: OID:2.16.840.1.113883.4.642.40.78.42.2

Profile of AllergyIntolerance for decision support/quality metrics. Defines the core set of elements and extensions for quality rule and measure authors.

USCDI+ Quality Element Support Expectations

Systems are expected to support this profile as part of implementing USCDI+ Quality V2 in FHIR and meeting the conformance requirements of this guide.

The following elements are specifically relevant to USCDI+ Quality V2 data classes and elements. Systems are expected to support these elements as applicable to their role in US Quality Core data exchange. See the Must Support section of this guide for more information. These elements are flagged as (USCDI+ Quality) in the formal profile views.

USCDI+ Quality Elements:

Profile element Description USCDI+ Quality Data Element(s)
code Code that identifies the allergy or intolerance Allergies and Intolerances: Drug Class Allergy Intolerance, Allergies and Intolerances: Medication Allergy Intolerance, Allergies and Intolerances: Non-Medication Allergy Intolerance
lastOccurrence Date(/time) of last known occurrence of a reaction Allergies and Intolerances: Reaction Date and Time
onset[x] When allergy or intolerance was identified Allergies and Intolerances: Allergy Intolerance Onset Date and Time
reaction Adverse Reaction Events linked to exposure to substance Allergies and Intolerances: Reaction
recordedDate Date first version of the resource instance was recorded Allergies and Intolerances: Allergy Intolerance Recorded Date and Time
recorder Who recorded the sensitivity Provenance: Author

Because this profile is derived directly or indirectly from US Core, systems are also expected to support the Must Support and Additional USCDI requirements specified by the US Core profile this profile inherits from. For more information about those requirements, refer to the US Core AllergyIntolerance Profile. The Formal Views section also provides the formal summary, definitions, terminology requirements, and mandatory element requirements.

Element Conformance Indicators by Profile Layer

Badges identify the profile layer where each conformance indicator is first introduced. Indicators introduced in an earlier layer remain applicable in later derived profiles.

Element conformance indicators organized by the profile layer where they are first introduced
Profile element FHIR US Core US Quality Core
clinicalStatus Must Support
verificationStatus Must Support
code Mandatory Must Support USCDI+ Quality
patient Mandatory Must Support
onset[x] USCDI+ Quality
recordedDate USCDI+ Quality
recorder Additional USCDI USCDI+ Quality
lastOccurrence USCDI+ Quality
reaction Must Support USCDI+ Quality
reaction.manifestation Mandatory Must Support

Cardinality note: “Mandatory” means the element has a minimum cardinality greater than zero. For nested elements, the cardinality indicator applies when the containing element is present.

Mandatory US Quality Core Server Search Parameters

The searches below are the focused set identified by US Quality Core as needed to retrieve USCDI+ Quality data for quality measurement and reporting. See the US Core FHIR RESTful Search API Requirements for detailed information on requirements by search parameter type.

Because this profile derives directly or indirectly from US Core, servers SHALL also support all mandatory searches described in the US Core Server CapabilityStatement requirements for AllergyIntolerance. When possible, this guide reuses mandatory searches from US Core and notes them with the EXISTING US CORE REQUIREMENT flag. While US Quality Core may restate US Core requirements to highlight searches directly relevant to USCDI+ Quality data access, US Core requirements not restated here remain applicable.

See the US Quality Core Server CapabilityStatement for complete requirements for the underlying AllergyIntolerance resource and Search Requirement Selection for how this focused set was selected.

Servers supporting this profile SHALL support the following search parameters and search parameter combinations:

  1. SHALL support searching for all AllergyIntolerance resources for a patient using the patient search parameter. EXISTING US CORE REQUIREMENT

    GET [base]/AllergyIntolerance?patient={Patient/}[id]

    Example:

    GET [base]/AllergyIntolerance?patient=Patient/example

    Implementation Notes: Fetches a bundle of US Quality Core AllergyIntolerance resources matching the specified search criteria. See how to search by reference.

    Rationale for inclusion: Supports patient-scoped retrieval of AllergyIntolerance resources for USCDI+ Quality workflows.
