High-level processes identified in guideline-based care

This resource allows for the definition of various types of plans as a sharable, consumable, and executable artifact. The resource is general enough to support the description of a broad range of clinical artifacts such as clinical decision support rules, order sets and protocols.

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.

Determines whether the artifact on which it appears is Enabled, as opposed to just Known.

Systems that are capable of storing and retrieving knowledge artifacts SHALL use this element to distinguish between a Known and an actively Enabled artifact. Behavior described by the artifact should only be implemented if this element is present and has a value of true.

Specifies the canonical URL of a Pathway or Strategy that this definition is part of.

For enrollment checking, if the computable PlanDefinition is not a Pathway or Strategy, then this extension is followed to attempt to determine a Pathway or Strategy to use for the enrollment check, recursively.

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.

A high-level category for the plan definition that distinguishes the kinds of systems that would be interested in the plan definition.

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.

The strength of the recommendation assigned to this reference. The code system used specifies the rating scale used to rate this recommendation while the code specifies the actual recommendation rating (represented as a coded value) associated with this recommendation.

Specifies whether the recommendation is "for" or "against" a particular activity. For example, the recommendation to prescribe a particular medication, versus the recommendation not to perform a particular procedure.

The quality of the evidence described. The code system used specifies the quality scale used to grade this evidence source while the code specifies the actual quality score (represented as a coded value) associated with the evidence.

A clinician-friendly rating, or score, for the recommendation; patient-friendly if the recommendation is patient-facing.

High-level processes identified in guideline-based care

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.

A description of when the action should be triggered.

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. 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.

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.

Defines input data requirements for the action.

Defines the outputs of the action, if any.

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.

Defines the types of relationships between actions.

An optional value describing when the action should be performed.

Indicates who should participate in performing the action described.

An Extension

A CapabilityStatement that specifies what capabilities a device must have in order to participant in this action of a PlanDefinition.

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.

The type of participant in the action.

The type of participant for the action.

The role the participant should play in performing the described action.

Personas used in identifying participants and their roles in computable content

The type of action to perform (create, update, remove).

The type of action to be performed.

Defines the grouping behavior for the action and its children.

Defines organization behavior of a group.

Defines the selection behavior for the action and its children.

Defines selection behavior of a group.

Defines the required behavior for the action.

Defines expectations around whether an action or action group is required.

Defines whether the action should usually be preselected.

Defines selection frequency behavior for an action or group.

Defines whether the action can be selected multiple times.

Defines behavior for an action or a group for how many times that item may be repeated.

A reference to an ActivityDefinition that describes the action to be taken in detail, or a PlanDefinition that describes a series of actions to be taken.

Note that the definition is optional, and if no definition is specified, a dynamicValue with a root ($this) path can be used to define the entire resource dynamically.

A reference to a StructureMap resource that defines a transform that can be executed to produce the intent resource using the ActivityDefinition instance as the input.

Note that when a referenced ActivityDefinition also defines a transform, the transform specified here generally takes precedence. In addition, if both a transform and dynamic values are specific, the dynamic values are applied to the result of the transform.

Customizations that should be applied to the statically defined resource. For example, if the dosage of a medication must be computed based on the patient's weight, a customization would be used to specify an expression that calculated the weight, and the path on the resource that would contain the result.

Dynamic values are applied in the order in which they are defined in the PlanDefinition resource. Note that when dynamic values are also specified by a referenced ActivityDefinition, the dynamicValues from the ActivityDefinition are applied first, followed by the dynamicValues specified here. In addition, if both a transform and dynamic values are specific, the dynamic values are applied to the result of the transform.

Sub actions that are contained within the action. The behavior of this action determines the functionality of the sub-actions. For example, a selection behavior of at-most-one indicates that of the sub-actions, at most one may be chosen as part of realizing the action definition.

This resource allows for the definition of various types of plans as a sharable, consumable, and executable artifact. The resource is general enough to support the description of a broad range of clinical artifacts such as clinical decision support rules, order sets and protocols.

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

Determines whether the artifact on which it appears is Enabled, as opposed to just Known.

Systems that are capable of storing and retrieving knowledge artifacts SHALL use this element to distinguish between a Known and an actively Enabled artifact. Behavior described by the artifact should only be implemented if this element is present and has a value of true.

Specifies the canonical URL of a Pathway or Strategy that this definition is part of.

For enrollment checking, if the computable PlanDefinition is not a Pathway or Strategy, then this extension is followed to attempt to determine a Pathway or Strategy to use for the enrollment check, recursively.

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).

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.

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

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].

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

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.

A short, descriptive, user-friendly title for the plan definition.

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

An explanatory or alternate title for the plan definition giving additional information about its content.

A high-level category for the plan definition that distinguishes the kinds of systems that would be interested in the plan definition.

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.).

The date (and optionally time) when the plan definition 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 plan definition changes.

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.

The name of the organization or individual that published the plan definition.

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.

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.

The period during which the plan definition content was or is planned to be in active use.

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.

Descriptive topics related to the content of the plan definition. Topics provide a high-level categorization of the definition that can be useful for filtering and searching.

High-level categorization of the definition, used for searching, sorting, and filtering.

Repositories must be able to determine how to categorize the plan definition so that it can be found by topical searches.

An individiual or organization primarily involved in the creation and maintenance of the content.

An individual or organization primarily responsible for internal coherence of the content.

An individual or organization primarily responsible for review of some aspect of the content.

An individual or organization responsible for officially endorsing the content for use in some setting.

Related artifacts such as additional documentation, justification, or bibliographic references.

Each related artifact is either an attachment, or a reference to another resource, but not both.

Plan definitions must be able to provide enough information for consumers of the content (and/or interventions or results produced by the content) to be able to determine and understand the justification for and evidence in support of the content.

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

Goals that describe what the activities within the plan are intended to achieve. For example, weight loss, restoring an activity of daily living, obtaining herd immunity via immunization, meeting a process improvement objective, etc.

Goal information needs to be captured for order sets, protocols, and care plan definitions to better describe the objectives of the protocol activities and to guide the creation of specific goals within the derived care plans and orders.

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.

The parameter whose value is to be tracked, e.g. body weight, blood pressure, or hemoglobin A1c level.

Identifies types of parameters that can be tracked to determine goal achievement.

The target value of the measure to be achieved to signify fulfillment of the goal, e.g. 150 pounds or 7.0%. Either the high or low or both values of the range can be specified. When a low value is missing, it indicates that the goal is achieved at any value at or below the high value. Similarly, if the high value is missing, it indicates that the goal is achieved at any value at or above the low value.

Indicates the timeframe after the start of the goal in which the goal should be met.

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.

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

An Extension

The strength of the recommendation assigned to this reference. The code system used specifies the rating scale used to rate this recommendation while the code specifies the actual recommendation rating (represented as a coded value) associated with this recommendation.

Specifies whether the recommendation is "for" or "against" a particular activity. For example, the recommendation to prescribe a particular medication, versus the recommendation not to perform a particular procedure.

The quality of the evidence described. The code system used specifies the quality scale used to grade this evidence source while the code specifies the actual quality score (represented as a coded value) associated with the evidence.

A clinician-friendly rating, or score, for the recommendation; patient-friendly if the recommendation is patient-facing.

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.

High-level processes identified in guideline-based care

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.

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. 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.

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.

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.

Defines the outputs of the action, if any.

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.

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

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.

An optional value describing when the action should be performed.

Indicates who should participate in performing the action described.

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

An Extension

A CapabilityStatement that specifies what capabilities a device must have in order to participant in this action of a PlanDefinition.
