Responsible Owner: Clinical Decision Support icon Work Group Maturity Level : 0   Trial Use Normative Security Category : Business Compartments : Not linked to any No defined compartments

The EvidenceVariable resource describes a "PICO" an element that knowledge (evidence, assertion, recommendation) (Evidence) is about.

14.10.1 17.11.1 Scope and Usage

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

The scope of the EvidenceVariable resource Resource is to describe a "PICO" an element that knowledge (evidence, assertion, recommendation) (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 Resource allows expression of the components of a PICO question in codeable and reusable formats. The EvidenceVariable.definition element has a CodeableReference datatype which can define the PICO component as a concept and/or reference to a Group Resource.

The EvidenceVariable Resource is also used within ResearchStudy to describe the endpoint for an outcome measure.

14.10.2 17.11.2 Boundaries and Relationships

Multiple resources The Resource describing evidence findings (Evidence, EffectEvidenceSynthesis, EffectEvidenceBit, RiskEvidenceSynthesis, RiskEvidenceBit) ( Evidence ) will reference EvidenceVariable to describe what the evidence findings are about.

This resource is referenced by EffectEvidenceSynthesis The Resource describing a research study protocol ( ResearchStudy ) will reference EvidenceVariable to describe the endpoint for an outcome measure.

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 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.

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 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.
