StructureDefinition-us-core-smokingstatus

This profile sets minimum expectations for the Observation resource to record, search, and fetch smoking status data associated with a patient. It identifies which core elements, extensions, vocabularies and value sets SHALL be present in the resource when using this profile.

Example Usage Scenarios:

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

  • Query for the Smoking Status of a patient
  • Record or update the Smoking Status of a patient

Mandatory and Must Support Data Elements

The following data-elements are mandatory (i.e data MUST be present) 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 Profile Definition below provides the formal summary, definitions, and terminology requirements.

Each Observation must have:

  1. a status
  2. a code for smoking observation
  3. a patient
  4. a date representing when the smoking status was recorded
  5. a result value code for smoking status

Profile specific implementation guidance:

  • Smoking observation LOINC = 72166-2 Tobacco smoking status NHIS

Quick Start

Below is an overview of the required set of Server RESTful FHIR interactions - for example, search and read operations - for this profile. See the Conformance requirements for a complete list of supported RESTful interactions for this IG.

  • The syntax used to describe the interactions is described here.
  • See the General Guidance 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 searching using the combination of the patient and code search parameters:
    • including optional support for composite OR search on code (e.g.code={system|}[code],{system|}[code],...)

    GET [base]/Observation?patient=[reference]&code=http://loinc.org|72166-2

    Example:

    1. GET [base]/Observation?patient=1032702&code=http://loinc.org|72166-2

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