ActRelationshipType    NormativeStandard1

A code specifying the meaning and purpose of every ActRelationship instance. Each of its values implies specific constraints to what kinds of Act objects can be related and in which way.

Discussion: The types of act relationships fall under one of 5 categories:

1.) (De)-composition, with composite (source) and component (target)

2.) Sequel which includes follow-up, fulfillment, instantiation, replacement, transformation, etc. that all have in common that source and target are Acts of essentially the same kind but with variances in mood and other attributes, and where the target exists before the source and the source refers to the target that it links back to.

3.) Pre-condition, trigger, reason, contraindication, with the conditioned Act at the source and the condition or reason at the target.

4.) Post-condition, outcome, goal and risk, with the Act at the source having the outcome or goal at the target.

5.) A host of functional relationships including support, cause, derivation, etc. generalized under the notion of "pertinence".

This table controls values for structural elements of the HL7 Reference Information Model. Therefore, it is part of the Normative Ballot for the RIM.

Lvl Type, Domain name and/or Mnemonic code Concept ID Mnemonic Print Name Definition/Description
1 A: ActRelationshipConditional A18977

Specifies under what circumstances (target Act) the source-Act may, must, must not or has occurred

2   S: ActRelationshipReason (RSON) S10321 RSON has reason

The reason or rationale for a service. A reason link is weaker than a trigger, it only suggests that some service may be or might have been a reason for some action, but not that this reason requires/required the action to be taken. Also, as opposed to the trigger, there is no strong timely relation between the reason and the action.

Discussion: In prior releases, the code "SUGG" (suggests) was expressed as "an inversion of the reason link." That code has been retired in favor of the inversion indicator that is an attribute of ActRelationship.

3     L:  (MITGT) C19986 MITGT mitigates

The source act removes or lessens the occurrence or effect of the target act.

2   L:  (CIND) C10323 CIND has contra-indication

A contraindication is just a negation of a reason, i.e. it gives a condition under which the action is not to be done. Both, source and target can be any kind of service; target service is in criterion mood. How the strength of a contraindication is expressed (e.g., relative, absolute) is left as an open issue. The priorityNumber attribute could be used.

2   L:  (PRCN) C10319 PRCN has pre-condition

A requirement to be true before a service is performed. The target can be any service in criterion mood. For multiple pre-conditions a conjunction attribute (AND, OR, XOR) is applicable.

2   L:  (TRIG) C10320 TRIG has trigger

A pre-condition that if true should result in the source Act being executed. The target is in typically in criterion mood. When reported after the fact (i.e. the criterion has been met) it may be in Event mood. A delay between the trigger and the triggered action can be specified.

Discussion: This includes the concept of a required act for a service or financial instrument such as an insurance plan or policy. In such cases, the trigger is the occurrence of a specific condition such as coverage limits being exceeded.

1 S: ActRelationshipHasComponent (COMP) S10318 COMP has component

A collection of sub-services as steps or subtasks performed for the source service. Services may be performed sequentially or concurrently.

2   L:  (ARR) C17911 ARR arrival

The relationship that links to a Transportation Act (target) from another Act (source) indicating that the subject of the source Act entered into the source Act by means of the target Transportation act.

2   L:  (DEP) C17912 DEP departure

The relationship that links to a Transportation Act (target) from another Act (source) indicating that the subject of the source Act departed from the source Act by means of the target Transportation act.

2   L:  (CTRLV) C17902 CTRLV has control variable

A relationship from an Act to a Control Variable. For example, if a Device makes an Observation, this relates the Observation to its Control Variables documenting the device's settings that influenced the observation.

1 S: ActRelationshipOutcome (OUTC) S10324 OUTC has outcome

An observation that should follow or does actually follow as a result or consequence of a condition or action (sometimes called "post-condition".) Target must be an observation as a goal, risk or any criterion. For complex outcomes a conjunction attribute

2   A: ActRelationshipObjective A19617

The target act is a desired outcome of the source act. Source is any act (typically an intervention). Target must be an observation in criterion mood.

3     L:  (OBJC) C10327 OBJC has continuing objective

A desired state that a service action aims to maintain. E.g., keep systolic blood pressure between 90 and 110 mm Hg. Source is an intervention service. Target must be an observation in criterion mood.

3     L:  (OBJF) C10326 OBJF has final objective

A desired outcome that a service action aims to meet finally. Source is any service (typically an intervention). Target must be an observation in criterion mood.

2   L:  (GOAL) C10325 GOAL has goal

A goal that one defines given a patient's health condition. Subsequently planned actions aim to meet that goal. Source is an observation or condition node, target must be an observation in goal mood.

2   L:  (RISK) C10328 RISK has risk

A noteworthy undesired outcome of a patient's condition that is either likely enough to become an issue or is less likely but dangerous enough to be addressed.

1 S: ActRelationshipPertains (PERT) S10329 PERT has pertinent information

This is a very unspecific relationship from one item of clinical information to another. It does not judge about the role the pertinent information plays.

2   A: ActRelationshipAccounting A14900

Codes that describe the relationship between an Act and a financial instrument such as a financial transaction, account or invoice element.

3     A: ActRelationshipCostTracking A19610

Expresses values for describing the relationship relationship between an InvoiceElement or InvoiceElementGroup and a billable act.

4       L:  (CHRG) C14904 CHRG has charge

A relationship that provides an ability to associate a financial transaction (target) as a charge to a clinical act (source). A clinical act may have a charge associated with the execution or delivery of the service.

The financial transaction will define the charge (bill) for delivery or performance of the service.

Charges and costs are distinct terms. A charge defines what is charged or billed to another organization or entity within an organization. The cost defines what it costs an organization to perform or deliver a service or product.

4       L:  (COST) C14903 COST has cost

A relationship that provides an ability to associate a financial transaction (target) as a cost to a clinical act (source). A clinical act may have an inherit cost associated with the execution or delivery of the service.

The financial transaction will define the cost of delivery or performance of the service.

Charges and costs are distinct terms. A charge defines what is charged or billed to another organization or entity within an organization. The cost defines what it costs an organization to perform or deliver a service or product.

3     A: ActRelationshipPosting A19609

Expresses values for describing the relationship between a FinancialTransaction and an Account.

4       L:  (CREDIT) C14902 CREDIT has credit

A credit relationship ties a financial transaction (target) to an account (source). A credit, once applied (posted), may have either a positive or negative effect on the account balance, depending on the type of account. An asset account credit will decrease the account balance. A non-asset account credit will decrease the account balance.

4       L:  (DEBIT) C14901 DEBIT has debit

A debit relationship ties a financial transaction (target) to an account (source). A debit, once applied (posted), may have either a positive or negative effect on the account balance, depending on the type of account. An asset account debit will increase the account balance. A non-asset account debit will decrease the account balance.

2   S: ActRelationshipHasSupport (SPRT) S10330 SPRT has support

Used to indicate that an existing service is suggesting evidence for a new observation. The assumption of support is attributed to the same actor who asserts the observation. Source must be an observation, target may be any service (e.g., to indicate a status post.)

3     L:  (SPRTBND) C17899 SPRTBND has bounded support

A specialization of "has support" (SPRT), used to relate a secondary observation to a Region of Interest on a multidimensional observation, if the ROI specifies the true boundaries of the secondary observation as opposed to only marking the approximate area. For example, if the start and end of an ST elevation episode is visible in an EKG, this relation would indicate the ROI bounds the "ST elevation" observation -- the ROI defines the true beginning and ending of the episode. Conversely, if a ROI simply contains ST elevation, but it does not define the bounds (start and end) of the episode, the more general "has support" relation is used. Likewise, if a ROI on an image defines the true bounds of a "1st degree burn", the relation "has bounded support" is used; but if the ROI only points to the approximate area of the burn, the general "has support" relation is used.

2   A: ActRelationshipTemporallyPertains A19587
3     L:  (SAS) C21308 SAS starts after start of

The source Act starts after the start of the target Act (i.e. if we say "ActOne SAS ActTwo", it means that ActOne starts after the start of ActTwo, therefore ActOne is the source and ActTwo is the target).

2   L:  (NAME) C10336 NAME assigns name

Used to assign a "name" to a condition thread. Source is a condition node, target can be any service.

2   L:  (AUTH) C14019 AUTH authorized by

A relationship in which the target act authorizes or certifies the source act.

2   L:  (COVBY) C14894 COVBY covered by

A relationship in which the source act is covered by or is under the authority of a target act. A financial instrument such as an Invoice Element is covered by one or more specific instances of an Insurance Policy.

2   L:  (EXPL) C10331 EXPL has explanation

This is the inversion of support. Used to indicate that a given observation is explained by another observation or condition.

2   L:  (PREV) C14018 PREV has previous instance

A relationship in which the target act is a predecessor instance to the source act. Generally each of these instances is similar, but no identical. In healthcare coverage it is used to link a claim item to a previous claim item that might have claimed for the same set of services.

2   L:  (REFV) C10335 REFV has reference values

Reference ranges are essentially descriptors of a class of result values assumed to be "normal", "abnormal", or "critical." Those can vary by sex, age, or any other criterion. Source and target are observations, the target is in criterion mood. This link type can act as a trigger in case of alarms being triggered by critical results.

2   L:  (SUBJ) C13971 SUBJ has subject

Relates an Act to its subject Act that the first Act is primarily concerned with.

Examples

  1. The first Act may be a ControlAct manipulating the subject Act

  2. The first act is a region of interest (ROI) that defines a region within the subject Act.

  3. The first act is a reporting or notification Act, that echos the subject Act for a specific new purpose.

Constraints

An Act may have multiple subject acts.

Rationale

The ActRelationshipType "has subject" is similar to the ParticipationType "subject", Acts that primarily operate on physical subjects use the Participation, those Acts that primarily operate on other Acts (other information) use the ActRelationship.

2   L:  (DRIV) C10334 DRIV is derived from

Associates a derived Act with its input parameters. E.G., an anion-gap observation can be associated as being derived from given sodium-, (potassium-,), chloride-, and bicarbonate-observations. The narrative content (Act.text) of a source act is wholly machine-derived from the collection of target acts.

2   L:  (CAUS) C10332 CAUS is etiology for

An assertion that a new observation was assumed to be the cause for another existing observation. The assumption is attributed to the same actor who asserts the observation. This is stronger and more specific than the support link. For example, a growth of Staphylococcus aureus may be considered the cause of an abscess. The source (cause) is typically an observation, but may be any service, while the target must be an observation.

2   L:  (MFST) C10333 MFST is manifestation of

An assertion that a new observation may be the manifestation of another existing observation or action. This assumption is attributed to the same actor who asserts the manifestation. This is stronger and more specific than an inverted support link. For example, an agitated appearance can be asserted to be the manifestation (effect) of a known hyperthyroxia. This expresses that one might not have realized a symptom if it would not be a common manifestation of a known condition. The target (cause) may be any service, while the source (manifestation) must be an observation.

2   L:  (ITEMSLOC) C20841 ITEMSLOC items located

Items located

2   L:  (LIMIT) C14896 LIMIT limited by

A relationship that limits or restricts the source act by the elements of the target act. For example, an authorization may be limited by a financial amount (up to $500). Target Act must be in EVN.CRIT mood.

2   L:  (EVID) C21572 EVID provides evidence for

Indicates that the target Act provides evidence in support of the action represented by the source Act. The target is not a 'reason' for the source act, but rather gives supporting information on why the source act is an appropriate course of action. Possible targets might be clinical trial results, journal articles, similar successful therapies, etc.

Rationale: Provides a mechanism for conveying clinical justification for non-approved or otherwise non-traditional therapies.

2   L:  (REFR) C14020 REFR refers to

A relationship in which the target act is referred to by the source act. This permits a simple reference relationship that distinguishes between the referent and the referee.

2   L:  (SUMM) C15988 SUMM summarized by

An act that contains summary values for a list or set of subordinate acts. For example, a summary of transactions for a particular accounting period.

1 S: ActRelationshipSequel (SEQL) S10337 SEQL is sequel

An act relationship indicating that the source act follows the target act. The source act should in principle represent the same kind of act as the target. Source and target need not have the same mood code (mood will often differ). The target of a sequel is called antecedent. Examples for sequel relationships are: revision, transformation, derivation from a prototype (as a specialization is a derivation of a generalization), followup, realization, instantiation.

2   S: ActRelationshipExcerpt (XCRPT) S18660 XCRPT Excerpts

The source is an excerpt from the target.

3     L:  (VRXCRPT) C18661 VRXCRPT Excerpt verbatim

The source is a direct quote from the target.

2   S: ActRelationshipFulfills (FLFS) S10342 FLFS fulfills

The source act fulfills (in whole or in part) the target act. Source act must be in a mood equal or more actual than the target act.

3     L:  (OCCR) C11614 OCCR occurrence

The source act is a single occurrence of a repeatable target act. The source and target act can be in any mood on the "completion track" but the source act must be as far as or further along the track than the target act (i.e., the occurrence of an intent can be an event but not vice versa).

3     L:  (OREF) C11628 OREF references order

Relates either an appointment request or an appointment to the order for the service being scheduled.

3     L:  (SCH) C11627 SCH schedules request

Associates a specific time (and associated resources) with a scheduling request or other intent.

2   S: ActRelationshipReplacement (RPLC) S10338 RPLC replaces

A replacement source act replaces an existing target act. The state of the target act being replaced becomes obselete, but the act is typically still retained in the system for historical reference. The source and target must be of the same type.

3     L:  (SUCC) C11616 SUCC succeeds

A new order that adds to, but does not completely replace its predecessor.

2   L:  (DOC) C11609 DOC documents

The source act documents the target act.

2   L:  (ELNK) C18865 ELNK episodeLink

Expresses an association that links two instances of the same act over time, indicating that the instance are part of the same episode, e.g. linking two condition nodes for episode of illness; linking two encounters for episode of encounter.

2   L:  (GEVL) C10346 GEVL evaluates (goal)

A goal-evaluation links an observation (intent or actual) to a goal to indicate that the observation evaluates the goal. Given the goal and the observation, a "goal distance" (e.g., goal to observation) can be "calculated" and need not be sent explicitly.

2   L:  (GEN) C10348 GEN has generalization

The generalization relationship can be used to express categorical knowledge about services (e.g., amilorid, triamterene, and spironolactone have the common generalization potassium sparing diuretic).

2   L:  (OPTN) C10347 OPTN has option

A relationship between a source Act that provides more detailed properties to the target Act.

The source act thus is a specialization of the target act, but instead of mentioning all the inherited properties it only mentions new property bindings or refinements.

The typical use case is to specify certain alternative variants of one kind of Act. The priorityNumber attribute is used to weigh refinements as preferred over other alternative refinements.

Example: several routing options for a drug are specified as one SubstanceAdministration for the general treatment with attached refinements for the various routing options.

2   L:  (INST) C10341 INST instantiates (master)

Used to capture the link between a potential service ("master" or plan) and an actual service, where the actual service instantiates the potential service. The instantiation may override the master's defaults.

2   L:  (APND) C10339 APND is appendage

An addendum (source) to an existing service object (target), containing supplemental information. The addendum is itself an original service object linked to the supplemented service object. The supplemented service object remains in place and its content and status are unaltered.

2   L:  (MTCH) C10345 MTCH matches (trigger)

A trigger-match links an actual service (e.g., an observation or procedure that took place) with a service in criterion mood. For example if the trigger is "observation of pain" and pain is actually observed, and if that pain-observation caused the trigger to fire, that pain-observation can be linked with the trigger.

2   L:  (REV) C14898 REV reverses

A relationship between a source Act that seeks to reverse or undo the action of the prior target Act.

Example: A posted financial transaction (e.g., a debit transaction) was applied in error and must be reversed (e.g., by a credit transaction) the credit transaction is identified as an undo (or reversal) of the prior target transaction.

Constraints: the "completion track" mood of the target Act must be equally or more "actual" than the source act. I.e., when the target act is EVN the source act can be EVN, or any INT. If the target act is INT, the source act can be INT.

2   L:  (XFRM) C11624 XFRM transformation

Used when the target Act is a transformation of the source Act. (For instance, used to show that a CDA document is a transformation of a DICOM SR document.)

2   L:  (UPDT) C10340 UPDT updates (condition)

A condition thread relationship specifically links condition nodes together to form a condition thread. The source is the new condition node and the target links to the most recent node of the existing condition thread.

1 A: x_ActRelationshipDocument A11610

Used to enumerate the relationships between two clinical documents for document management.

2   L:  (APND) C10339 APND is appendage

An addendum (source) to an existing service object (target), containing supplemental information. The addendum is itself an original service object linked to the supplemented service object. The supplemented service object remains in place and its content and status are unaltered.

2   L:  (RPLC) C10338 RPLC replaces

A replacement source act replaces an existing target act. The state of the target act being replaced becomes obselete, but the act is typically still retained in the system for historical reference. The source and target must be of the same type.

2   L:  (XFRM) C11624 XFRM transformation

Used when the target Act is a transformation of the source Act. (For instance, used to show that a CDA document is a transformation of a DICOM SR document.)

1 A: x_ActRelationshipEntry A19446

Used to enumerate the relationships between a CDA section and its contained entries.

2   L:  (COMP) C10318 COMP has component

A collection of sub-services as steps or subtasks performed for the source service. Services may be performed sequentially or concurrently.

2   L:  (DRIV) C10334 DRIV is derived from

Associates a derived Act with its input parameters. E.G., an anion-gap observation can be associated as being derived from given sodium-, (potassium-,), chloride-, and bicarbonate-observations. The narrative content (Act.text) of a source act is wholly machine-derived from the collection of target acts.

1 A: x_ActRelationshipEntryRelationship A19447

Used to enumerate the relationships between two CDA entries.

2   L:  (XCRPT) C18660 XCRPT Excerpts

The source is an excerpt from the target.

2   L:  (GEVL) C10346 GEVL evaluates (goal)

A goal-evaluation links an observation (intent or actual) to a goal to indicate that the observation evaluates the goal. Given the goal and the observation, a "goal distance" (e.g., goal to observation) can be "calculated" and need not be sent explicitly.

2   L:  (COMP) C10318 COMP has component

A collection of sub-services as steps or subtasks performed for the source service. Services may be performed sequentially or concurrently.

2   L:  (RSON) C10321 RSON has reason

The reason or rationale for a service. A reason link is weaker than a trigger, it only suggests that some service may be or might have been a reason for some action, but not that this reason requires/required the action to be taken. Also, as opposed to the trigger, there is no strong timely relation between the reason and the action.

Discussion: In prior releases, the code "SUGG" (suggests) was expressed as "an inversion of the reason link." That code has been retired in favor of the inversion indicator that is an attribute of ActRelationship.

2   L:  (SUBJ) C13971 SUBJ has subject

Relates an Act to its subject Act that the first Act is primarily concerned with.

Examples

  1. The first Act may be a ControlAct manipulating the subject Act

  2. The first act is a region of interest (ROI) that defines a region within the subject Act.

  3. The first act is a reporting or notification Act, that echos the subject Act for a specific new purpose.

Constraints

An Act may have multiple subject acts.

Rationale

The ActRelationshipType "has subject" is similar to the ParticipationType "subject", Acts that primarily operate on physical subjects use the Participation, those Acts that primarily operate on other Acts (other information) use the ActRelationship.

2   L:  (SPRT) C10330 SPRT has support

Used to indicate that an existing service is suggesting evidence for a new observation. The assumption of support is attributed to the same actor who asserts the observation. Source must be an observation, target may be any service (e.g., to indicate a status post).

2   L:  (CAUS) C10332 CAUS is etiology for

An assertion that a new observation was assumed to be the cause for another existing observation. The assumption is attributed to the same actor who asserts the observation. This is stronger and more specific than the support link. For example, a growth of Staphylococcus aureus may be considered the cause of an abscess. The source (cause) is typically an observation, but may be any service, while the target must be an observation.

2   L:  (MFST) C10333 MFST is manifestation of

An assertion that a new observation may be the manifestation of another existing observation or action. This assumption is attributed to the same actor who asserts the manifestation. This is stronger and more specific than an inverted support link. For example, an agitated appearance can be asserted to be the manifestation (effect) of a known hyperthyroxia. This expresses that one might not have realized a symptom if it would not be a common manifestation of a known condition. The target (cause) may be any service, while the source (manifestation) must be an observation.

2   L:  (REFR) C14020 REFR refers to

A relationship in which the target act is referred to by the source act. This permits a simple reference relationship that distinguishes between the referent and the referee.

2   L:  (SAS) C21308 SAS starts after start of

The source Act starts after the start of the target Act (i.e. if we say "ActOne SAS ActTwo", it means that ActOne starts after the start of ActTwo, therefore ActOne is the source and ActTwo is the target).

1 A: x_ActRelationshipExternalReference A19000

Used to enumerate the relationships between a CDA entry and an externally referenced act.

2   L:  (XCRPT) C18660 XCRPT Excerpts

The source is an excerpt from the target.

2   L:  (ELNK) C18865 ELNK episodeLink

Expresses an association that links two instances of the same act over time, indicating that the instance are part of the same episode, e.g. linking two condition nodes for episode of illness; linking two encounters for episode of encounter.
