Resource Profile: US Core Specimen Profile

Active as of 2022-09-27 Computable Name: USCoreSpecimenProfile

This profile sets minimum expectations for the Specimen resource to record, search, and fetch “substances being sampled or tested. (e.g., nasopharyngeal swab, whole blood, serum, urine, wound swab)” associated with a patient to promote interoperability and adoption through common implementation. It identifies which core elements, extensions, vocabularies, and value sets SHALL be present in the resource and constrains the way the elements are used when using this profile. It provides the floor for standards development for specific use cases.

Example Usage Scenarios:

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

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 Specimen Must Have:

  1. a specimen code

Each Specimen Must Support:

  1. a patient

Profile Specific Implementation Guidance:

  • Since the binding is extensible when a code is unavailable, just text is allowed.
  • in addition to Specimen search criteria, clients may request Specimen resources be included with Observation or DiagnosticReport resource query. An example query is provided in the Notes section below.

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.

  • The syntax used to describe the interactions is described here.

  • Servers providing access to specimen data can use US Core SMART Scopes for:
  • 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.

Mandatory Search Parameters:

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

  1. SHALL support both read Specimen by id AND Specimen search using the _id search parameter:

    GET [base]/Specimen/[id] or GET [base]/Specimen?_id=[id]

    Example:

    1. GET [base]/Specimen?_id=123

    Implementation Notes: (how to search by the logical id of the resource)

Optional Search Parameters:

The following search parameter combinations SHOULD be supported:

  1. SHOULD support searching for all specimens for a patient using the patient search parameter:

    GET [base]/Specimen?patient={Type/}[id]

    Example:

    1. GET [base]/Specimen?patient=1137192

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

Including Specimen when searching for an Observation or DiagnosticReport

Servers MAY support the _include parameter to request that additional resources be included in the response of a search query. For example, when searching for an Observation or DiagnosticReport that references Specimen, the client can use the _include parameter to retrieve information about a specimen associated with the search results. The syntax for querying an Observation and the associated Specimen is:

GET [base]/[Resource-type]?[parameter1]=[value1]{&...}&_include=Observation:specimen

Example:

GET [base]/Observation?_id=9163726&_include=Observation:specimen
