US Core Implementation Guide
8.0.0-ballot - Ballot United States of America flag

US Core Implementation Guide, published by HL7 International / Cross-Group Projects. This guide is not an authorized publication; it is the continuous build for version 8.0.0-ballot built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/US-Core/ and changes regularly. See the Directory of published versions

Resource Profile: US Core Observation Pregnancy Intent Profile

The US Core Observation Pregnancy Intent Profile inherits from the FHIR Observation resource; refer to it for scope and usage definitions. This profile meets the requirements of the U.S. Core Data for Interoperability (USCDI) Pregnancy Status Data Element. This profile sets minimum expectations for the Observation resource to record, search, and fetch the patient's intention to become pregnant. It specifies which core elements, extensions, vocabularies, and value sets SHALL be present in the resource and constrains how the elements are used. Providing the floor for standards development for specific use cases promotes interoperability and adoption.

Example Usage Scenarios:

The following are example usage scenarios for this profile:

  • Query for a patient's pregnancy intention
  • Record or update a past or present pregnancy intention

Mandatory and Must Support Data Elements

The following data elements must always be present (Mandatory definition) or must be supported if the data is present in the sending system (Must Support definition). They are presented below in a simple human-readable explanation. Profile specific guidance and examples are provided as well. The Formal Views below provides the formal summary, definitions, and terminology requirements.

Each Observation Must Have:

  1. a status
  2. a code for pregnancy intention observation
  3. a patient
  4. when the observation occurred
  5. the pregnancy intention

Each Observation Must Support:

  1. a category code of "social-history"

Profile Specific Implementation Guidance:

Usage:

Changes since version 7.0.0:

  • No changes

    • Formal Views of Profile Content
