This page is part of the Quality Improvement Core Framework (v7.0.0: STU7 (v7.0.0)) based on FHIR (HL7® FHIR® Standard) R4. This is the current published version. For a full list of available versions, see the Directory of published versions

Resource Profile: QICore AllergyIntolerance

Official URL: http://hl7.org/fhir/us/qicore/StructureDefinition/qicore-allergyintolerance Version: 7.0.0
Standards status: Trial-use Maturity Level: 4 Computable Name: QICoreAllergyIntolerance

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

"Must Have", "QI Elements" and "primary code path" are defined in the QI-Core Must Support section.
Must Have:
  • patient: (QI) Who the sensitivity is for
  • code: (QI) Code that identifies the allergy or intolerance
QI Elements:
  • verificationStatus: (QI) unconfirmed | confirmed | refuted | entered-in-error
  • onset[x]: (QI) When allergy or intolerance was identified
  • clinicalStatus: (QI) active | inactive | resolved
  • criticality: (QI) low | high | unable-to-assess
  • recordedDate: (QI) Date first version of the resource instance was recorded
  • type: (QI) allergy | intolerance - Underlying mechanism (if known)
  • category: (QI) food | medication | environment | biologic
  • lastOccurrence: (QI) Date(/time) of last known occurrence of a reaction
  • reaction: (QI) Adverse Reaction Events linked to exposure to substance
Primary code path: code
(PCPath) This element is the primary code path for this resource CQL Retrieve

Usage

This example represents a situation where the subject is currently experiencing, or is at risk of, a reaction to the identified substance.

define "Statin Allergy Intolerance":
  ["AllergyIntolerance": "Statin Allergen"] StatinAllergyIntolerance
    where (StatinAllergyIntolerance.clinicalStatus is null or StatinAllergyIntolerance.clinicalStatus ~ Global."allergy-active")

See the patterns page for implementation and usage patterns.
