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.
Example Usage Scenarios:
The following are example usage scenarios for this profile:
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.

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.
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
The following search parameters and search parameter combinations SHALL be supported:
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:
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)
patient
and code
search parameters:
code
(e.g.code={system|}[code],{system|}[code],...
)GET [base]/Observation?patient={Type/}[id]&code={system|}[code]{,{system|}[code],...}
Example:
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)
patient
and category
