• value @ system

Describes the intention of how one or more practitioners intend to deliver care for a particular patient, group or community for a period of time, possibly limited to care for a specific condition or set of conditions.

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 its narrative along with other profiles, value sets, etc.

These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, nor can they have their own independent transaction scope. This is allowed to be a Parameters resource if and only if it is referenced by a resource that provides context/meaning.

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.

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 managable, 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.

Business identifiers assigned to this care plan by the performer or other systems which remain constant as the resource is updated and propagates from server to server.

This is a business identifier, not a resource identifier (see discussion). It is best practice for the identifier to only appear on a single resource instance, however business practices may occasionally dictate that multiple resource instances with the same identifier can exist - possibly even with different resource types. For example, multiple Patient and a Person resource instance might share the same social insurance number.

Allows identification of the care plan as it is known by various participating systems and in a way that remains consistent across servers.

The purpose of this identifier.

Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.

Identifies the purpose for this identifier, if known .

Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.

Establishes the namespace for the value - that is, an absolute URL that describes a set values that are unique.

Identifier.system is always case sensitive.

There are many sets of identifiers. To perform matching of two identifiers, we need to know what set we're dealing with. The system identifies a particular set of unique identifiers.

The portion of the identifier typically relevant to the user and which is unique within the context of the system.

If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the http://hl7.org/fhir/StructureDefinition/rendered-value). Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe.

Indicates whether the plan is currently being acted upon, represents future intentions or is now a historical record.

The unknown code is not to be used to convey other statuses. The unknown code should be used when one of the statuses applies, but the authoring system doesn't know the current state of the care plan.

This element is labeled as a modifier because the status contains the code entered-in-error that marks the plan as not currently valid.

Indicates whether the plan is currently being acted upon, represents future intentions or is now a historical record.

Allows clinicians to determine whether the plan is actionable or not.

Indicates the level of authority/intentionality associated with the care plan and where the care plan fits into the workflow chain.

This element is labeled as a modifier because the intent alters when and how the resource is actually applicable. This element is expected to be immutable. E.g. A "proposal" instance should never change to be a "plan" instance or "order" instance. Instead, a new instance 'basedOn' the prior instance should be created with the new 'intent' value.

Codes indicating the degree of authority/intentionality associated with a care plan.

Proposals/recommendations, plans and orders all use the same structure and can exist in the same fulfillment chain.

Identifies the patient or group whose intended care is described by the plan.

The Encounter during which this CarePlan was created or to which the creation of this record is tightly associated.

This will typically be the encounter the event occurred within, but some activities may be initiated prior to or after the official completion of an encounter but still be tied to the context of the encounter. CarePlan activities conducted as a result of the care plan may well occur as part of other encounters.

Indicates when the plan did (or is intended to) come into effect and end.

Any activities scheduled as part of the plan should be constrained to the specified period regardless of whether the activities are planned within a single encounter/episode or across multiple encounters/episodes (e.g. the longitudinal management of a chronic condition).

Allows tracking what plan(s) are in effect at a particular time.

Identifies an action that has occurred or is a planned action to occur as part of the plan. For example, a medication to be used, lab tests to perform, self-monitoring that has occurred, education etc.

Allows systems to prompt for performance of planned activities, and validate plans against best practice.

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 details of the proposed activity represented in a specific resource.

Standard extension exists (http://hl7.org/fhir/StructureDefinition/resource-pertainsToGoal) that allows goals to be referenced from any of the referenced resources in CarePlan.activity.plannedActivityReference.
The goal should be visible when the resource referenced by CarePlan.activity.plannedActivityReference is viewed independently from the CarePlan. Requests that are pointed to by a CarePlan using this element should not point to this CarePlan using the "basedOn" element. i.e. Requests that are part of a CarePlan are not "based on" the CarePlan.

Details in a form consistent with other applications and contexts of use.

General notes about the care plan not covered elsewhere.

Used to capture information that applies to the plan as a whole that doesn't fit into discrete elements.

Describes the intention of how one or more practitioners intend to deliver care for a particular patient, group or community for a period of time, possibly limited to care for a specific condition or set of conditions.

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

Within the context of the FHIR RESTful interactions, the resource has an id except for cases like the create and conditional update. Otherwise, the use of the resouce id depends on the given use case.

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 its 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-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 a 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, nor can they have their own independent transaction scope. This is allowed to be a Parameters resource if and only if it is referenced by a resource that provides context/meaning.

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.

May be used to represent additional information that is not part of the basic definition of the resource. To make the use of extensions safe and managable, 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.

• value @ url

The purpose of this identifier.

Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.

Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.

A coded type for the identifier that can be used to determine which identifier to use for a specific purpose.

This element deals only with general categories of identifiers. It SHOULD not be used for codes that correspond 1..1 with the Identifier.system. Some identifiers may fall into multiple categories due to common usage. Where the system is known, a type is unnecessary because the type is always part of the system definition. However systems often need to handle identifiers where the system is not known. There is not a 1:1 relationship between type and system, since many different systems have the same type.

Allows users to make use of identifiers when the identifier system is not known.

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 managable, there is a strict set of governance applied to the definition and use of extensions.

• value @ url

A reference to a code defined by a terminology system.

Codes may be defined very casually in enumerations, or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information. Ordering of codings is undefined and SHALL NOT be used to infer meaning. Generally, at most only one of the coding values will be labeled as UserSelected = true.

Allows for alternative encodings within a code system, and translations to other code systems.

• value @ url

The identification of the code system that defines the meaning of the symbol in the code.

The URI may be an OID (urn:oid:...) or a UUID (urn:uuid:...). OIDs and UUIDs SHALL be references to the HL7 OID registry. Otherwise, the URI should come from HL7's list of FHIR defined special URIs or it should be an absolute reference to some definition that establishes the system clearly and unambiguously.

Need to be unambiguous about the source of the definition of the symbol.

The version of the code system which was used when choosing this code. Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.

Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

A symbol in syntax defined by the system. The symbol may be a predefined code or an expression in a syntax defined by the coding system (e.g. post-coordination).

Need to refer to a particular code in the system.

A representation of the meaning of the code in the system, following the rules of the system.

Need to be able to carry a human-readable meaning of the code for readers that do not know the system.

Indicates that this coding was chosen by a user directly - e.g. off a pick list of available items (codes or displays).

Amongst a set of alternatives, a directly chosen code is the most appropriate starting point for new translations. There is some ambiguity about what exactly 'directly chosen' implies, and trading partner agreement may be needed to clarify the use of this element and its consequences more completely.

This has been identified as a clinical safety criterium - that this exact system/code pair was chosen explicitly, rather than inferred by the system based on some rules or language processing.

A human language representation of the concept as seen/selected/uttered by the user who entered the data and/or which represents the intended meaning of the user.

Very often the text is the same as a displayName of one of the codings.

The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source.

Establishes the namespace for the value - that is, an absolute URL that describes a set values that are unique.

Identifier.system is always case sensitive.

There are many sets of identifiers. To perform matching of two identifiers, we need to know what set we're dealing with. The system identifies a particular set of unique identifiers.

The portion of the identifier typically relevant to the user and which is unique within the context of the system.

If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the http://hl7.org/fhir/StructureDefinition/rendered-value). Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe.

Time period during which identifier is/was valid for use.

Organization that issued/manages the identifier.

The Identifier.assigner may omit the .reference element and only contain a .display element reflecting the name or other textual information about the assigning organization.

The URL pointing to a FHIR-defined protocol, guideline, questionnaire or other definition that is adhered to in whole or in part by this CarePlan.

The URL pointing to an externally maintained protocol, guideline, questionnaire or other definition that is adhered to in whole or in part by this CarePlan.

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

A higher-level request resource (i.e. a plan, proposal or order) that is fulfilled in whole or in part by this care plan.

Allows tracing of the care plan and tracking whether proposals/recommendations were acted upon.

Completed or terminated care plan whose function is taken by this new care plan.

The replacement could be because the initial care plan was immediately rejected (due to an issue) or because the previous care plan was completed, but the need for the action described by the care plan remains ongoing.

Allows tracing the continuation of a therapy or administrative process instantiated through multiple care plans.

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

Each care plan is an independent request, such that having a care plan be part of another care plan can cause issues with cascading statuses. As such, this element is still being discussed.

Indicates whether the plan is currently being acted upon, represents future intentions or is now a historical record.

The unknown code is not to be used to convey other statuses. The unknown code should be used when one of the statuses applies, but the authoring system doesn't know the current state of the care plan.

Allows clinicians to determine whether the plan is actionable or not.

Indicates the level of authority/intentionality associated with the care plan and where the care plan fits into the workflow chain.

This element is labeled as a modifier because the intent alters when and how the resource is actually applicable. This element is expected to be immutable. E.g. A "proposal" instance should never change to be a "plan" instance or "order" instance. Instead, a new instance 'basedOn' the prior instance should be created with the new 'intent' value.

Proposals/recommendations, plans and orders all use the same structure and can exist in the same fulfillment chain.

Identifies what "kind" of plan this is to support differentiation between multiple co-existing plans; e.g. "Home health", "psychiatric", "asthma", "disease management", "wellness plan", etc.

There may be multiple axes of categorization and one plan may serve multiple purposes. In some cases, this may be redundant with references to CarePlan.addresses.

Used for filtering what plan(s) are retrieved and displayed to different types of users.

Human-friendly name for the care plan.

A description of the scope and nature of the plan.

Provides more detail than conveyed by category.

Identifies the patient or group whose intended care is described by the plan.

The Encounter during which this CarePlan was created or to which the creation of this record is tightly associated.

This will typically be the encounter the event occurred within, but some activities may be initiated prior to or after the official completion of an encounter but still be tied to the context of the encounter. CarePlan activities conducted as a result of the care plan may well occur as part of other encounters.

Indicates when the plan did (or is intended to) come into effect and end.

Any activities scheduled as part of the plan should be constrained to the specified period regardless of whether the activities are planned within a single encounter/episode or across multiple encounters/episodes (e.g. the longitudinal management of a chronic condition).

Allows tracking what plan(s) are in effect at a particular time.

Represents when this particular CarePlan record was created in the system, which is often a system-generated date.

When populated, the custodian is responsible for the care plan. The care plan is attributed to the custodian.

The custodian might or might not be a contributor.

Identifies the individual(s), organization or device who provided the contents of the care plan.

Collaborative care plans may have multiple contributors.

Identifies all people and organizations who are expected to be involved in the care envisioned by this plan.

Allows representation of care teams, helps scope care plan. In some cases may be a determiner of access permissions.

Identifies the conditions/problems/concerns/diagnoses/etc. whose management and/or mitigation are handled by this plan.

Use CarePlan.addresses.concept when a code sufficiently describes the concern (e.g. condition, problem, diagnosis, risk). Use CarePlan.addresses.reference when referencing a resource, which allows more information to be conveyed, such as onset date. CarePlan.addresses.concept and CarePlan.addresses.reference are not meant to be duplicative. For a single concern, either CarePlan.addresses.concept or CarePlan.addresses.reference can be used. CarePlan.addresses.concept may be a summary code, or CarePlan.addresses.reference may be used to reference a very precise definition of the concern using Condition. Both CarePlan.addresses.concept and CarePlan.addresses.reference can be used if they are describing different concerns for the care plan.

The element can identify risks addressed by the plan as well as concerns. Also scopes plans - multiple plans may exist addressing different concerns.

Identifies portions of the patient's record that specifically influenced the formation of the plan. These might include comorbidities, recent procedures, limitations, recent assessments, etc.

Use "concern" to identify specific conditions addressed by the care plan. supportingInfo can be used to convey one or more Advance Directives or Medical Treatment Consent Directives by referencing Consent or any other request resource with intent = directive.

Identifies barriers and other considerations associated with the care plan.

Describes the intended objective(s) of carrying out the care plan.

Goal can be achieving a particular change or merely maintaining a current state or even slowing a decline.

Provides context for plan. Allows plan effectiveness to be evaluated by clinicians.

Identifies an action that has occurred or is a planned action to occur as part of the plan. For example, a medication to be used, lab tests to perform, self-monitoring that has occurred, education etc.

Allows systems to prompt for performance of planned activities, and validate plans against best practice.

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 managable, 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.

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.

Identifies the activity that was performed. For example, an activity could be patient education, exercise, or a medication administration. The reference to an "event" resource, such as Procedure or Encounter or Observation, represents the activity that was performed. The requested activity can be conveyed using the CarePlan.activity.plannedActivityReference (a reference to a “request” resource).

Note that this should not duplicate the activity status (e.g. completed or in progress). The activity performed is independent of the outcome of the related goal(s). For example, if the goal is to achieve a target body weight of 150 lbs and an activity is defined to exercise, then the activity performed could be amount and intensity of exercise performed whereas the goal outcome is an observation for the actual body weight measured.

Links plan to resulting actions.

Notes about the adherence/status/progress of the activity.

This element should NOT be used to describe the activity to be performed - that occurs either within the resource pointed to by activity.detail.reference or in activity.detail.description.

Can be used to capture information about adherence, progress, concerns, etc.

The details of the proposed activity represented in a specific resource.

Standard extension exists (http://hl7.org/fhir/StructureDefinition/resource-pertainsToGoal) that allows goals to be referenced from any of the referenced resources in CarePlan.activity.plannedActivityReference.
The goal should be visible when the resource referenced by CarePlan.activity.plannedActivityReference is viewed independently from the CarePlan. Requests that are pointed to by a CarePlan using this element should not point to this CarePlan using the "basedOn" element. i.e. Requests that are part of a CarePlan are not "based on" the CarePlan.

Details in a form consistent with other applications and contexts of use.

General notes about the care plan not covered elsewhere.

Used to capture information that applies to the plan as a whole that doesn't fit into discrete elements.
