Clinical Decision Support icon Work Group Maturity Level : 1   Trial Use Security Category : Business Compartments : No defined compartments

The EvidenceVariable resource describes an element that knowledge (Evidence) is about.

14.14.1 14.13.1 Scope and Usage

This resource is a definition resource from a FHIR workflow perspective - see Workflow , specifically Definition .

The scope of the EvidenceVariable Resource is to describe an element that knowledge (evidence) is about. The EvidenceVariable Resources are expected to be used with Evidence Resources to facilitate searching and knowledge representation.

Evidence may be reported for different types of knowledge. One commonly used format for expression of what evidence is about is the "PICO" format. PICO stands for:

Population - the population within which exposures and outcomes are being considered

Intervention - the conditional state or exposure state being described for which one is expressing the risk of or effect on an outcome

Comparison - the alternative conditional state or alternative exposure state when one is comparing states for the effect on an outcome

Outcome - the result or effect of an intervention or exposure in a population

PICO (and its variants like PECO using E for Exposure or PICOT) PICOT adding T for Timing) is a universal acronym used in evidence-based medicine communities to clearly express research questions and evidence findings.

The EvidenceVariable Resource allows expression of the components of a PICO question in codeable and reusable formats. As an exception, the Population specification will NOT use the EvidenceVariable Resource. The Population specification will use EvidenceVariable.definition element has a CodeableReference datatype which can define the Group Resource to facilitate interoperability in matching Evidence Resources PICO component as a concept and/or reference to actual groups. a Group Resource.

Ballot question: The EvidenceVariable Resource has been modified to support expressions of complex eligibility criteria for implementer communities seeking alternatives is also used within ResearchStudy to Group Resource for eligibility criteria for clinical trials. With these changes, the current EvidenceVariable Resource has greater flexibility than describe the Group Resource endpoint for Population specification. Please submit a ballot comment to note if you support a proposed change to the EvidenceVariable Scope and Usage to delete "As an exception, the Population specification will NOT use the EvidenceVariable Resource" and "The Population specification will use the Group Resource to facilitate interoperability in matching Evidence Resources to actual groups." outcome measure.

14.14.2 14.13.2 Boundaries and Relationships

The Resource describing evidence findings ( Evidence ) will reference EvidenceVariable to describe what the evidence findings are about.

The Resource describing a research study protocol ( ResearchStudy ) will reference EvidenceVariable to describe the endpoint for an outcome measure.

This SHOULD be globally unique and SHOULD be a literal address at which an authoritative instance of this evidence variable is (or will be) published.

For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence. To provide a version consistent with the Decision Support Service specification, use the format Major.Minor.Revision (e.g. 1.0.0).

EvidenceVariable ( DomainResource ) + MetadataResource An absolute URI that is used to identify this evidence variable when it is referenced in a specification, model, design or an instance; also called its canonical identifier. This SHOULD be globally unique and SHOULD be a literal address at which an authoritative instance of this evidence variable is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the evidence variable is stored on different servers url : uri [0..1] A formal identifier that is used to identify this evidence variable when it is represented in other formats, or referenced in a specification, model, design or an instance identifier : Identifier [0..*] The identifier that is used to identify this version of the evidence variable when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the evidence variable author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence. To provide a version consistent with the Decision Support Service specification, use the format Major.Minor.Revision (e.g. 1.0.0). For more information on versioning knowledge assets, refer to the Decision Support Service specification.
