The US Core Pregnancy Status Observation 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. It sets minimum expectations for the Observation resource to record, search, and fetch the patient's state or condition of being 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.

This page has new content for US Core Version 8.0.0

Example Usage Scenarios:

The following are example usage scenarios for this profile:

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

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 status observation
  3. a patient
  4. when the observation occurred
  5. the pregnancy status

Each Observation Must Support:

  1. a category code of "social-history"

Additional USCDI Requirements:

These Additional USCDI Requirements elements are not Mandatory or Must Support but are required for ONC Health IT certification testing and are included in the formal definition of the profile and the Observation examples.

  1. a performer*

Profile Specific Implementation Guidance:

  • *The profile elements Observation.performer and Observation.device communicate the individual level provenance author data corresponding to the U.S. Core Data for Interoperability (USCDI) Provenance Author Data Elements.

  • The [US Core Pregnancy Status Codes] value set includes SNOMED CT codes and the HL7 V3 code for the concept "unknown". These codes have historically been used to communicate the pregnancy status of a patient.

Usage:

Changes since version 7.0.0:

  • The data elements list has changed

    • Formal Views of Profile Content

    Description of Profiles, Differentials, Snapshots and how the different presentations work.

    Notes:

    Quick Start

    Below is an overview of the required Server RESTful FHIR interactions for this profile - for example, search and read operations - when supporting the US Core interactions to access this profile's information (Profile Support + Interaction Support). Note that systems that support only US Core Profiles (Profile Only Support) are not required to support these interactions. See the US Core Server CapabilityStatement for a complete list of supported RESTful interactions for this IG.

    • See the Scopes Format section for a description of the SMART scopes syntax.
    • See the Search Syntax section for a description of the US Core search syntax.
    • See the General Requirements section for additional rules and expectations when a Server requires status parameters.
    • See the General Guidance section for additional guidance on searching for multiple patients.

    US Core Scopes

    Servers providing access to social history data SHALL support these US Core SMART Scopes:

    • resource level scopes: <patient|user|system>/Observation.rs

    • granular scopes: <patient|user|system>/Observation.rs?category=http://terminology.hl7.org//CodeSystem-observation-category|social-history

    Mandatory Search Parameters:

    The following search parameters and search parameter combinations SHALL be supported:

    1. SHALL support searching using the combination of the patient and category search parameters:

      GET [base]/Observation?patient={Type/}[id]&category=http://terminology.hl7.org/CodeSystem/observation-category|laboratory

      Example:

      1. GET [base]/Observation?patient=1134281&amp;category=social-history

      Implementation Notes: Fetches a bundle of all Observation resources for the specified patient and a category code = laboratory (how to search by reference and how to search by token)

    2. SHALL support searching using the combination of the patient and code search parameters:
      • including optional support for OR search on code (e.g.code={system|}[code],{system|}[code],...)

      GET [base]/Observation?patient={Type/}[id]&code={system|}[code]{,{system|}[code],...}

      Example:

      1. GET [base]/Observation?patient=1134281&amp;code=http://loinc.org|82810-3

      Implementation Notes: Fetches a bundle of all Observation resources for the specified patient and observation code(s). SHOULD support search by multiple report codes. The Observation code parameter searches `Observation.code only. (how to search by reference and how to search by token)

    3. SHALL support searching using the combination of the patient and category and date search parameters:
      • including support for these date comparators: gt,lt,ge,le
      • including optional support for AND search on date (e.g.date=[date]&date=[date]]&...)

      GET [base]/Observation?patient={Type/}[id]&category=http://terminology.hl7.org/CodeSystem/observation-category|laboratory&date={gt|lt|ge|le}[date]{&date={gt|lt|ge|le}[date]&...}

      Example:

      1. GET [base]Observation?patient=555580&category=social-history&date=ge2018-03-14T00:00:00Z

      Implementation Notes: Fetches a bundle of all Observation resources for the specified patient and date and a category code = laboratory (how to search by reference and how to search by token and how to search by date)

    Optional Search Parameters:

    The following search parameter combinations SHOULD be supported:

    1. SHOULD support searching using the combination of the patient and category and status search parameters:
      • including support for OR search on status (e.g.status={system|}[code],{system|}[code],...)

      GET [base]/Observation?patient={Type/}[id]&category=http://terminology.hl7.org/CodeSystem/observation-category|laboratory&status={system|}[code]{,{system|}[code],...}

      Example:

      1. GET [base]/Observation?patient=1134281&category=social-history&status=final

      Implementation Notes: Fetches a bundle of all Observation resources for the specified patient and category = laboratory and status (how to search by reference and how to search by token)

    2. SHOULD support searching using the combination of the patient and category and _lastUpdated search parameters:
      • including support for these _lastUpdated comparators: gt,lt,ge,le
      • including optional support for AND search on _lastUpdated (e.g._lastUpdated=[date]&_lastUpdated=[date]]&...)

      GET [base]/Observation?patient={Type/}[id]&category={system|}[code]&_lastUpdated={gt|lt|ge|le}[date]{&_lastUpdated={gt|lt|ge|le}[date]&...}

      Example:

      1. GET [base]Observation?patient=555580&social-history&_lastUpdated=ge2024-01-01T00:00:00Z

      Implementation Notes: Fetches a bundle of all Observation resources for the specified patient and category and _lastUpdated. See the US Core General Guidance page for Searching Using lastUpdated. (how to search by reference and how to search by token and how to search by date)

    3. SHOULD support searching using the combination of the patient and code and date search parameters:
      • including optional support for OR search on code (e.g.code={system|}[code],{system|}[code],...)
      • including support for these date comparators: gt,lt,ge,le
      • including optional support for AND search on date (e.g.date=[date]&date=[date]]&...)

      GET [base]/Observation?patient={Type/}[id]&code={system|}[code]{,{system|}[code],...}&date={gt|lt|ge|le}[date]{&date={gt|lt|ge|le}[date]&...}

      Example:

      1. GET [base]Observation?patient=555580&code=http://loinc.org|82810-3&date=ge2019-01-01T00:00:00Z

      Implementation Notes: Fetches a bundle of all Observation resources for the specified patient and date and report code(s). SHOULD support search by multiple report codes. (how to search by reference and how to search by token and how to search by date)
