D.20.0 U.S. Data Access Framework (DAF) Smoking Status Profile

D.20.0.1 Scope and Usage

This profile sets expectations for use of the Observation resource to record Smoking Status of a patient within the DAF FHIR IG. This profile identifies which core elements, extensions, vocabularies and value sets must be Supported by DAF actors. For the definition of Supported please refer to DAF FHIR IG. The data elements identified by the profile are based on ONC 2014 Edition S&CC and DAF use cases. The mappings between the ONC 2014 Edition S&CC data elements and DAF data elements are captured in the table below, where the first column identifies the ONC 2014 Edition S&CC data element name, the second column maps the ONC 2014 Edition S&CC data elements to DAF data elements which are derived from ONC 2014 Edition S&CC standards and DAF use cases and lastly the third column identifies the mapping to FHIR resources and attributes.

D.20.0.2 Meaningful Use Data Element Mapping

The DAF-SmokingStatus profile mapping to Meaningful Use data elements and FHIR Resources are as shown below.For an overview of how the DAF profiles and data elements were derived from ONC 2014 Edition S&CC please refer to DAF FHIR IG data mapping section.

D.20.0.3 Boundaries and Relationships

This profile relies on the following other profiles:

  • DAF-Patient is used by DAF-SmokingStatus profile to refer to patients.
  • FHIR Extensibility defines how extensions can be applied to FHIR resources and data types. Specifically the data-absent-reason extension can be used to code data elements with missing information when appropriate. See DAF FHIR IG for additional guidance.

D.20.0.4 Content

D.20.0.4.1 Search Parameters

The full list of supported search parameters are can be accessed at DAF Requestor conformance expectations and DAF Responder conformance expectations.

D.20.0.4.2 Example Usage Scenarios

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

  • Query for Smoking Status of a particular patient
  • Query for all patients who have had a history of smoking
  • Query for all patients who have never had tobacco
  • Query for all patients who have smoked during a time period of interest
  • Query for all patients who have a smoking history and are in an age group

D.20.0.4.3 Profile specific implementation guidance

Implementers need to be mindful of the following during their implementation

    Smoking Status Applicability: The Smoking Status values describe point-in-time smoking status, and implementers have to be mindful of the semantic meaning while using these codes to describe smoking behavior. For example, if I want to say that a patient used to smoke heavily between 2000 and 2010, it does not make sense to use the code for Former smoker', along with an effectivePeriod representing 2000-2010. This is because 'Former smoker' did not apply during that time range. Instead implementers should use a 'current smoker' along with a time range representing 2000-2010.

    See DAF FHIR IG for implementation guidance common to all profiles.
