Defines a shareable US Public Health PlanDefinition.

A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.

Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc.

Indicates the address where the report has to be sent.

May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.

Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

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

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.

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.

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.

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

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

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

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

Business version of the PlanDefinition

There may be different plan definition 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 plan definition with the format [url]|[version].

Name for this PlanDefinition (computer friendly)

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.

Support human navigation and code generation.

Title for this PlanDefinition

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

Type of this PlanDefinition

The type of PlanDefinition.

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

Allows filtering of plan definitions that are appropriate for use versus not.

The lifecycle status of an artifact.

A Boolean value to indicate that this plan definition is authored for testing purposes (or education/evaluation/marketing) and is not intended to be used for genuine usage.

Allows filtering of plan definitions that are appropriate for use versus not.

Enables experimental content to be developed following the same lifecycle that would be used for a production-level plan definition.

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

The possible types of subjects for a plan definition (E.g. Patient, Practitioner, Organization, Location, etc.).

Date the PlanDefinition was last changed

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

Name of the agency that published this PlanDefinition

Usually an organization but may be an individual. The publisher (or steward) of the plan definition is the organization or individual primarily responsible for the maintenance and upkeep of the plan definition. This is not necessarily the same individual or organization that developed and initially authored the content. The publisher is the primary point of contact for questions or issues with the plan definition. This item SHOULD be populated unless the information is available from context.

Helps establish the "authority/credibility" of the plan definition. May also allow for contact.

Contact details to assist a user in finding and communicating with the publisher.

May be a web site, an email address, a telephone number, etc.

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

This description can be used to capture details such as why the plan definition 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 plan definition 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 plan definition is presumed to be the predominant language in the place the plan definition was created).

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 plan definition instances.

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

Assist in searching for appropriate content.

A legal or geographic region in which the plan definition is intended to be used.

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

Countries and regions within which this artifact is targeted for use.

The period during which the PlanDefinition is valid

The effective period for a plan definition 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 might be published in 2015.

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

The start of the time period when this PlanDefinition goes into effect

If the low element is missing, the meaning is that the low boundary is not known.

A reference to a Library resource containing any formal logic used by the plan definition.

An action or group of actions to be taken as part of the plan.

Note that there is overlap between many of the elements defined here and the ActivityDefinition resource. When an ActivityDefinition is referenced (using the definition element), the overlapping elements in the plan override the content of the referenced ActivityDefinition unless otherwise documented in the specific elements. See the PlanDefinition resource for more detailed information.

May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.

Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

A brief description of the action used to provide a summary to display to the user.

A code that provides meaning for the action or action group. For example, a section may have a LOINC code for the section of a documentation template.

The set of actions that can be used to create plan definition

A description of when the action should be triggered.

Indicates the types of named events to subscribe to from the EHR.

The type of triggering event.

The type of trigger.

An expression that describes applicability criteria or start/stop conditions for the action.

When multiple conditions of the same kind are present, the effects are combined using AND semantics, so the overall condition is true only if all the conditions are true.

May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants.

The kind of condition.

Applicability criteria are used to determine immediate applicability when a plan definition is applied to a given context. Start and stop criteria are carried through application and used to describe enter/exit criteria for an action.

Defines the kinds of conditions that can appear on actions.

An expression that returns true or false, indicating whether the condition is satisfied.

The expression may be inlined or may be a reference to a named expression within a logic library referenced by the library element.

Defines input data requirements for the action.

Points to an existing input or output element that provides data to this input or results as output for the action.

The type of the required data, specified as the type name of a resource. For profiles, this value is set to the type of the base resource of the profile.

A list of all the concrete types defined in this version of the FHIR specification - Abstract Types, Data Types and Resource Types.

Defines the outputs of the action, if any.

The type of the required data, specified as the type name of a resource. For profiles, this value is set to the type of the base resource of the profile.

A list of all the concrete types defined in this version of the FHIR specification - Abstract Types, Data Types and Resource Types.

A relationship to another action such as "before" or "30-60 minutes after start of".

When an action depends on multiple actions, the meaning is that all actions are dependencies, rather than that any of the actions are a dependency.

May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants.

The element id of the related action.

The relationship of this action to the related action.

Defines the types of relationships between actions.

A duration or range of durations to apply to the relationship. For example, 30-60 minutes before.

A duration or range of durations to apply to the relationship. For example, 30-60 minutes before.

An optional value describing when the action should be performed.

Defines a shareable US Public Health PlanDefinition.

The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.

The only time that a resource does not have an id is when it is being submitted to the server using a create operation.

The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.

A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.

Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc.

The base language in which the resource is written.

Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).

A human language.

A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.

Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.

These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope.

This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.

An Extension

Indicates the address where the report has to be sent.

May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions.

Explanation of why this plan definition is needed and why it has been designed as it has.

This element does not describe the usage of the plan definition. Instead, it 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 plan definition.

A detailed description of how the plan definition is used from a clinical perspective.

A copyright statement relating to the plan definition and/or its contents. Copyright statements are generally legal restrictions on the use and publishing of the plan definition.

Consumers must be able to determine any legal restrictions on the use of the plan definition and/or its content.

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

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

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

If specified, this date follows 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.

Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

A user-visible prefix for the action.

The title of the action displayed to a user.

A brief description of the action used to provide a summary to display to the user.

A text equivalent of the action to be performed. This provides a human-interpretable description of the action when the definition is consumed by a system that might not be capable of interpreting it dynamically.

Indicates how quickly the action should be addressed with respect to other actions.

Identifies the level of importance to be assigned to actioning the request.

A code that provides meaning for the action or action group. For example, a section may have a LOINC code for the section of a documentation template.

The set of actions that can be used to create plan definition

A description of why this action is necessary or appropriate.

This is different than the clinical evidence documentation, it's an actual business description of the reason for performing the action.

Didactic or other informational resources associated with the action that can be provided to the CDS recipient. Information resources can include inline text commentary and links to web resources.

Identifies goals that this action supports. The reference must be to a goal element defined within this plan definition.

A code or group definition that describes the intended subject of the action and its children, if any.

The subject of an action overrides the subject at a parent action or on the root of the PlanDefinition if specified.

In addition, because the subject needs to be resolved during realization, use of subjects in actions (or in the ActivityDefinition referenced by the action) resolves based on the set of subjects supplied in context and by type (i.e. the patient subject would resolve to a resource of type Patient).

The possible types of subjects for a plan definition (E.g. Patient, Practitioner, Organization, Location, etc.).

Multiple steps in a protocol often have different groups of steps that are focused on testing different things. The subject of an action specifies the focus of the action and any child actions.

A description of when the action should be triggered.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

Indicates the types of named events to subscribe to from the EHR.

The type of triggering event.

The type of trigger.

A formal name for the event. This may be an absolute URI that identifies the event formally (e.g. from a trigger registry), or a simple relative URI that identifies the event in a local context.

An event name can be provided for all event types, but is required for named events. If a name is provided for a type other than named events, it is considered to be a shorthand for the semantics described by the formal description of the event.

The timing of the event (if this is a periodic trigger).

The triggering data of the event (if this is a data trigger). If more than one data is requirement is specified, then all the data requirements must be true.

This element shall be present for any data type trigger.

A boolean-valued expression that is evaluated in the context of the container of the trigger definition and returns whether or not the trigger fires.

This element can be only be specified for data type triggers and provides additional semantics for the trigger. The context available within the condition is based on the type of data event. For all events, the current resource will be available as context. In addition, for modification events, the previous resource will also be available. The expression may be inlined, or may be a simple absolute URI, which is a reference to a named expression within a logic library referenced by a library element or extension within the containing resource. If the expression is a FHIR Path expression, it evaluates in the context of a resource of one of the type identified in the data requirement, and may also refer to the variable %previous for delta comparisons on events of type data-changed, data-modified, and data-deleted which will always have the same type.

Need to be able to formally describe the triggering criteria.

An expression that describes applicability criteria or start/stop conditions for the action.

When multiple conditions of the same kind are present, the effects are combined using AND semantics, so the overall condition is true only if all the conditions are true.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions.

May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

The kind of condition.

Applicability criteria are used to determine immediate applicability when a plan definition is applied to a given context. Start and stop criteria are carried through application and used to describe enter/exit criteria for an action.

Defines the kinds of conditions that can appear on actions.

An expression that returns true or false, indicating whether the condition is satisfied.

The expression may be inlined or may be a reference to a named expression within a logic library referenced by the library element.

Defines input data requirements for the action.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

May be used to represent additional information that is not part of the basic definition of the element.

Points to an existing input or output element that provides data to this input or results as output for the action.

The type of the required data, specified as the type name of a resource. For profiles, this value is set to the type of the base resource of the profile.
