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 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.

  • 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, search parameter combinations SHALL be supported. Any listed search parameter modifiers, comparators, chains and composites SHALL also be supported UNLESS they are listed as “optional” in which case they SHOULD 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)
