US Core Implementation Guide (Release 1)

This page is part of the US Core (v1.0.0: STU1) based on FHIR R3. The current version which supercedes this version is 5.0.1. For a full list of available versions, see the Directory of published versions

1.0 - StructureDefinition-us-core-allergyintolerance

This profile sets minimum expectations for the AllergyIntolerance resource to record, search and fetch allergies/adverse reactions associated with a patient. It identifies the mandatory core elements, extensions, vocabularies and value sets which SHALL be present in the AllergyIntolerance resource when using this profile.

Example Usage Scenarios:

The following are example usage scenarios for the US Core AllergyIntolerance profile:

  • Query for Allergies belonging to a Patient
  • Record or update a Patient Allergy
Mandatory Data Elements and Terminology

The following data-elements are mandatory (i.e data MUST be present). These are presented below in a simple human-readable explanation. Profile specific guidance and examples are provided as well. The Formal Profile Definition below provides the formal summary, definitions, and terminology requirements.

Each AllergyIntolerance must have:

  1. a status of the allergy
  2. a verification status
  3. a code which tells you what the patient is allergic to
  4. a patient

Profile specific implementation guidance:

  • No Known Allergies may be represented using the US Core-AllergyIntolerance profile with appropriate negation code in AllergyIntolerence.code.

1.3 - Quick Start

Below is an overview of the required search and read operations for this profile. See the Conformance requirements for the US Core Server for a complete list of supported RESTful operations and search parameters for this IG.

GET /AllergyIntolerance?patient=[id]

Example: GET [base]/AllergyIntolerance?patient=1137192

Support: Mandatory to support search by patient.

Implementation Notes: Search for all allergies for a patient. Fetches a bundle of all AllergyIntolerance resources for the specified patient (how to search by reference).
