US Core Implementation Guide (Release 1.1.0 Ballot )

SD.16 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 Data Elements and Terminology

The following data-elements are mandatory (i.e data MUST be present). These 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 fixed 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:

SD.16.2 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.

GET [base]/Observation?patient=[id]&code=72166-2

Support: Mandatory to support search by patient and code = ‘72166-2’.

Example: GET [base]/Observation?patient=1032702&code=72166-2

Implementation Notes: Search based on smoking status LOINC code. Fetches a bundle of all Observation resources with Observation.code of Tobacco Smoking Status for the specified patient (how to search by reference) and (how to search by token).
