A pattern to be followed by resources that represent a specific proposal, plan and/or order for some sort of action or service.

An absolute URL URI that is used to identify this {{title}} when it is referenced in a specification, model, design or an instance. instance; also called its canonical identifier. This SHALL be a URL, SHOULD be globally unique, unique and SHOULD be an a literal address at which an authoritative instance of this {{title}} is (or will be) published. The This URL SHOULD include can be the major version target of a canonical reference. It SHALL remain the {{title}}. For more information see Technical and Business Versions . same when the {{title}} is stored on different servers.

Allows the {{title}} to be referenced by a single globally unique identifier.

Can be a urn:uuid: or a urn:oid:, urn:oid: but real http: addresses are preferred. This is Multiple instances may share the URI that will be used same URL if they have a distinct version.

The determination of when making canonical references 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 resource. decision are found in Technical and Business Versions .

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.

Business identifiers assigned A formal identifier that is used to identify this {{title}} by the performer and/or other systems. These identifiers remain constant as the resource when it is updated and propagates from server to server. represented in other formats, or referenced in a specification, model, design or an instance.

Allows identification of externally provided and/or usable business identifiers to be easily associated with the {{title}} as it is known by various participating systems and in a way that remains consistent across servers. {{title}}.

Note: This is a business identifier, not a resource identifier (see discussion ). It Typically, this is best practice used for the identifier to only appear on a single resource instance, however business practices may occasionally dictate identifiers that multiple resource instances with the same identifier can exist - possibly even with different resource types. For example, multiple Patient go in an HL7 V3 II (instance identifier) data type, and a Person resource instance might share can then identify this {{title}} outside of FHIR, where it is not possible to use the same social insurance number. logical URI.

The identifier that is used to identify this version of the {{title}} when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the {{title}} 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 are orderable. can be placed in a lexicographical sequence.

There may be multiple different instances of a {{title}} {{title}}s that have the same identifier url 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 {{title}} with the format [url]|[version]. The version SHOULD NOT contain a '#' - see Business Version .

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

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 and a 0 if the version ordering can't be successfully be determined.

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

Supports code generation.

The name is not expected to be globally unique. The name should be a simple alphanumeric type no-whitespace name to ensure that it is machine-processing friendly.

A short, descriptive, user-friendly title for the {{title}}.

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

The canonical URL pointing to another FHIR-defined protocol, guideline, orderset or other definition that is adhered to in whole or in part by this definition.

Protocols and order sets may be refinements of more generic protocols and order sets.

The URL pointing to an externally-defined protocol, guideline, orderset or other definition that is adhered to in whole or in part by this definition.

Protocols and order sets may be refinements of more generic protocols and order sets.

This might be an HTML page, PDF, etc. or could just be a non-resolvable URI identifier.

A larger definition of which this particular definition is a component or step.

E.g. Drug administration as part of a procedure, procedure as part of observation, etc.

[The allowed reference resources may be adjusted as appropriate for the event resource].

Cardinality 0..* Type canonical ( Definition [ ActivityDefinition , EventDefinition , EvidenceVariable , Measure , OperationDefinition , PlanDefinition , Questionnaire , ResearchDefinition , ResearchElementDefinition , SubscriptionTopic ]) Requirements As new versions of a protocol or guideline are defined, allows identification The current state of what versions are replaced by a new instance. this {{title}}.

Enables tracking the lifecycle of the content and filtering of {{title}}s that are appropriate for use versus not.

A nominal state-transition diagram can be found in the [[definition.html#statemachine | Definition pattern]] documentation

Unknown does not represent "other" 'other' - one of the defined statuses must apply. Unknown is used when the authoring system is not sure what the current status is.

A flag Boolean value to indicate that this {{title}} is authored for testing purposes (or education/evaluation/marketing), education/evaluation/marketing) and is not intended to be used for genuine usage.

Enables experimental content to be developed following the same life-cycle as lifecycle that would be used for a production-level {{title}} would. {{title}}.

Allows filtering of {{title}} {{title}}s that are appropriate for use vs. versus not.

A code or group definition that describes the intended subject of instantiations of this definition.

Many protocols, order sets and guidelines are inted for use only with specific types of patients or subjects.

For draft definitions, indicates the The date of initial creation. For active definitions, represents (and optionally time) when the {{title}} was last significantly changed. The date of activation. For withdrawn definitions, indicates must change when the date business version changes and it must change if the status code changes. In addition, it should change when the substantive content of withdrawal. the {{title}} changes.

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 {{title}}. Additional specific dates may be added as extensions or be found by consulting Provenances associated with past versions of the resource.

This description can be used to capture details such as why the {{title}} 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 module {{title}} as conveyed in the text 'text' field of the resource itself. This item SHOULD be populated unless the information is available from context.

The content was developed with a focus and intent of supporting the contexts that are listed. These terms 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 of code system definitions. for appropriate {{title}}s.

It may be possible for the {{title}} to be used in jurisdictions other than those for which it was originally designed or intended.

Explains Explanation of why this {{title}} is needed and why it has been designed as it has.

This element does not describe the usage of the {{title}}. Rather Instead, it is for provides traceability of ''why'' the resource is either needed or ''why'' it is defined as it is. This may be used to point to source materials or specifications that drove the structure of this {{title}}.

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

The date on which the asset resource content was last reviewed. Review happens periodically after that, approval but doesn't does not change the original approval date.

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.

If specified, this is usually after date follows the original approval date.

The period during which the {{title}} content was or is planned to be effective. in active use.

Allows establishing a transition before a resource comes into effect and also allows for a sunsetting process when new versions of the {{title}} are or are expected to be used instead.

The effective period for a {{title}} determines when the content is applicable for usage and is independent of publication and review dates. For example, a measure intended to be used for the year 2016 would might be published in 2015.
