Detailed Descriptions for the elements in the Evidence resource.

Evidence
Element IdEvidence
Definition

This represents statistics, certainty, both the intended and actual population, and evidence variables.

Cardinality0..*
TypeDomainResource
Invariants
Defined on this element
evi-0Warning Name should be usable as an identifier for the module by machine processing applications such as code generationname.matches('[A-Z]([A-Za-z0-9_]){0,254}')
Evidence.url
Element IdEvidence.url
Definition

An absolute URI that is used to identify this evidence 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 summary is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the summary is stored on different servers.

Cardinality0..1
Typeuri
Requirements

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

Summarytrue
Comments

Can be a urn:uuid: or a urn:oid: but real http: addresses are preferred. Multiple instances may share the same URL if they have a distinct version.

Evidence.identifier
Element IdEvidence.identifier
Definition

A formal identifier that is used to identify this summary when it is represented in other formats, or referenced in a specification, model, design or an instance.

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 summary outside of FHIR, where it is not possible to use the logical URI.

Evidence.version
Element IdEvidence.version
Definition

The identifier that is used to identify this version of the summary when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the summary 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.

NoteThis is a business versionId, not a resource version id (see discussion)
Cardinality0..1
Typestring
Summarytrue
Comments

The determination of when to create a new version of a resource (same url, new version) vs. defining a new artifact is up to the author. Considerations for making this decision are found in Technical and Business Versions.

Evidence.title
Element IdEvidence.title
Definition

A short, descriptive, user-friendly title for the summary.

Cardinality0..1
Typestring
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.

Evidence.status
Element IdEvidence.status
Definition

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

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 summarys s that are appropriate for use versus not.

Evidence.useContext
Element IdEvidence.useContext
Definition

The content was developed with a focus and intent of supporting the contexts that are listed. These contexts may be general categories (gender, age, ...) or may be references to specific programs (insurance plans, studies, ...) and may be used to assist with indexing and searching for appropriate evidence instances.

Cardinality0..*
TypeUsageContext
Requirements

Assist in searching for appropriate content.

Summarytrue
Comments

When multiple useContexts are specified, there is no expectation that all or any of the contexts apply.

Evidence.date
Element IdEvidence.date
Definition

The date (and optionally time) when the summary was published. The date must change when the business version changes and it must change if the status code changes. In addition, it should change when the substantive content of the summary changes.

Cardinality0..1
TypedateTime
Alternate NamesRevision Date
Summarytrue
Comments

Note that this is not the same as the resource last-modified-date, since the resource may be a secondary representation of the summary. Additional specific dates may be added as extensions or be found by consulting Provenances associated with past versions of the resource.

Evidence.approvalDate
Element IdEvidence.approvalDate
Definition

The date on which the resource content was approved by the publisher. Approval happens once when the content is officially approved for usage.

Cardinality0..1
Typedate
Comments

The 'date' element may be more recent than the approval date because of minor changes or editorial corrections.

Evidence.lastReviewDate
Element IdEvidence.lastReviewDate
Definition

The date on which the resource content was last reviewed. Review happens periodically after approval but does not change the original approval date.

Cardinality0..1
Typedate
Requirements

Gives a sense of how "current" the content is. Resources that have not been reviewed in a long time may have a risk of being less appropriate/relevant.

Comments

If specified, this date follows the original approval date.

Evidence.contributor

Evidence.description
Element IdEvidence.description
Definition

A free text natural language description of the evidence from a consumer's perspective.

Cardinality0..1
Typemarkdown
Comments

This description can be used to capture details such as why the evidence was built, comments about misuse, instructions for clinical use and interpretation, literature references, examples from the paper world, etc. It is not a rendering of the evidence as conveyed in the 'text' field of the resource itself. This item SHOULD be populated unless the information is available from context (e.g. the language of the evidence is presumed to be the predominant language in the place the evidence was created).
