14.13 Resource EvidenceVariable - Content

Clinical Decision Support Work GroupMaturity Level: 0 Trial UseSecurity Category: Business Compartments: Not linked to any defined compartments

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

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 or PICOT) 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 the Group resource to facilitate interoperability in matching Evidence resources to actual groups.

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

This resource is referenced by Evidence.

This resource implements the Definition pattern.
