Detailed Descriptions for the elements in the EvidenceVariable resource.

EvidenceVariable
Element IdEvidenceVariable
Definition

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

Short DisplayA definition of an exposure, outcome, or other variable
Cardinality0..*
TypeMetadataResource
Requirements

Need to be able to define and reuse the definition of individual elements of a research question.

Summaryfalse
Comments

The EvidenceVariable may be an exposure variable (intervention, condition, or state), a measured variable (outcome or observed parameter), or other variable (such as confounding factor).

Invariants
Defined on this element
cnl-0Warning Name should be usable as an identifier for the module by machine processing applications such as code generationname.exists() implies name.matches('^[A-Z]([A-Za-z0-9_]){1,254}$')
EvidenceVariable.url
Element IdEvidenceVariable.url
Definition

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.

Short DisplayCanonical identifier for this evidence variable, represented as a URI (globally unique)
Cardinality0..1
Typeuri
Requirements

Allows the evidence variable to be referenced by a single globally unique identifier.

Summarytrue
Comments

In some cases, the resource can no longer be found at the stated url, but the url itself cannot change. Implementations can use the meta.source element to indicate where the current master source of the resource can be found.

Invariants
Defined on this element
cnl-1Warning URL should not contain | or # - these characters make processing canonical references problematicexists() implies matches('^[^|# ]+$')
EvidenceVariable.identifier
Element IdEvidenceVariable.identifier
Definition

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.

Short DisplayAdditional identifier for the evidence variable
NoteThis is a business identifier, not a resource identifier (see discussion)
Cardinality0..*
TypeIdentifier
Requirements

Allows externally provided and/or usable business identifiers to be easily associated with the module.

Summarytrue
Comments

Typically, this is used for identifiers that can go in an HL7 V3 II (instance identifier) data type, and can then identify this evidence variable outside of FHIR, where it is not possible to use the logical URI.

EvidenceVariable.version
Element IdEvidenceVariable.version
Definition

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. Note that a version is required for non-experimental active artifacts.

Short DisplayBusiness version of the evidence variable
NoteThis is a business versionId, not a resource version id (see discussion)
Cardinality0..1
Typestring
Summarytrue
Comments

There may be different evidence variable instances that have the same identifier but different versions. The version can be appended to the url in a reference to allow a reference to a particular business version of the evidence variable with the format [url]|[version]. The version SHOULD NOT contain a '#' - see Business Version.

EvidenceVariable.versionAlgorithm[x]
Element IdEvidenceVariable.versionAlgorithm[x]
Definition

Indicates the mechanism used to compare versions to determine which is more current.

Short DisplayHow to compare versions
Cardinality0..1
Terminology BindingVersion Algorithm (Extensible)
Typestring|Coding
[x] NoteSee Choice of Datatypes for further information about how to use [x]
Summarytrue
Comments

If set as a string, this is a FHIRPath expression that has two additional context variables passed in - %version1 and %version2 and will return a negative number if version1 is newer, a positive number if version2 is newer, and a 0 if the version ordering can't successfully be determined.

EvidenceVariable.name
Element IdEvidenceVariable.name
Definition

A natural language name identifying the evidence variable. This name should be usable as an identifier for the module by machine processing applications such as code generation.

Short DisplayName for this evidence variable (computer friendly)
Cardinality0..1
Typestring
Requirements

Support human navigation and code generation.

Summarytrue
Comments

The name is not expected to be globally unique. The name should be a simple alphanumeric type name to ensure that it is machine-processing friendly.

Invariants
Affect this element
cnl-0Warning Name should be usable as an identifier for the module by machine processing applications such as code generationname.exists() implies name.matches('^[A-Z]([A-Za-z0-9_]){1,254}$')
EvidenceVariable.title
Element IdEvidenceVariable.title
Definition

A short, descriptive, user-friendly title for the evidence variable.

Short DisplayName for this evidence variable (human friendly)
Cardinality0..1
Typestring
Summarytrue
Comments

This name does not need to be machine-processing friendly and may contain punctuation, white-space, etc.

EvidenceVariable.shortTitle
Element IdEvidenceVariable.shortTitle
Definition

The short title provides an alternate title for use in informal descriptive contexts where the full, formal title is not necessary.

Short DisplayTitle for use in informal contexts
Cardinality0..1
Typestring
Requirements

Need to be able to reference the content by a short description, but still provide a longer, more formal title for the content.

Summarytrue
EvidenceVariable.status
Element IdEvidenceVariable.status
Definition

The status of this evidence variable. Enables tracking the life-cycle of the content.

Short Displaydraft | active | retired | unknown
Cardinality1..1
Terminology BindingPublicationStatus (Required)
Typecode
Is Modifiertrue (Reason: This is labeled as "Is Modifier" because applications should not use a retired {{title}} without due consideration)
Summarytrue
Comments

Allows filtering of evidence variables that are appropriate for use versus not.

See guidance around (not) making local changes to elements here.

EvidenceVariable.experimental
Element IdEvidenceVariable.experimental

Summaryfalse
EvidenceVariable.date
Element IdEvidenceVariable.date
Definition

Short DisplayDate last changed
Cardinality0..1
TypedateTime
Alternate NamesRevision Date
Summarytrue
Comments

The date is often not tracked until the resource is published, but may be present on draft content. Note that this is not the same as the resource last-modified-date, since the resource may be a secondary representation of the evidence variable. Additional specific dates may be added as extensions or be found by consulting Provenances associated with past versions of the resource.

See guidance around (not) making local changes to elements here.

EvidenceVariable.publisher
Element IdEvidenceVariable.publisher
