LinkAssertion

An assertion between two coded entries where the relationship (assertion) is not specifically modelled elsewhere.

Used by:
[1..1] [M] classCode (CS {CNE:ActClass } ) { Fixed="OBS" }
Indicates that this is an observation.
[1..1] [M] moodCode (CS {CNE:ActMood } ) { Fixed="EVN" }
Indicates that this is an event.
[1..1] [M] code (CD {CNE:LinkAssertionSnCT } )

A SNOMED CT code taken from the LinkAssertionSnCT vocabulary.

The Concept Descriptor (CD) with CDA URL datatype/flavour shall be used to carry this information as follows:

  • The code attribute shall contain a code from the relevant vocabulary.
  • The codeSystem attribute shall contain the OID for SnomedCT.
  • The displayName attribute shall carry a description associated with the code in SnomedCT.
  • The originalText element can be used to carry a reference element. This can link the coded item to the relevant text in the CDA section.
  • qualifier (s) may be used if required.
Note the implementation guidance for the domain where this template is used should be consulted regarding correct usage of the originalText element.


[1..1] [M] effectiveTime (IVL<TS>)

The time/duration that the LinkAssertion was relevant.

The date range shall be carried as follows:

If a single point in time is to be carried the Date or Time Point data type shall be used:

  • The center attribute shall contain the date.
This is used if the exact time/date is not known.

If both a start date and an end date are present the Date or Time Interval Complete data type shall be used:

  • The low attribute shall contain the start date.
  • The high attribute shall contain the end date.
Used when the full relevant time interval is known.

If only a start date is present the Date or Time Interval After data type shall be used:

  • The low attribute shall contain the start date.
This is used if the link assertion is still relevant (ongoing)

If only an end date is present the Date or Time Interval Before data type shall be used:

  • The high attribute shall contain the end date.


Used if the assertion is no longer relevant after the end date but it is not known whenthe assertion was first made.

[1..1] [M] id (II)

This is a unique identifier for this instance of a Link Assertion.

The Identifier Global datatype flavour is used to carry the identifier as follows:

  • The root attribute shall contain a DCE UUID.
[1..1] [M] statusCode (CS {CNE:ActStatus } ) { Default="completed" }

The status of the link assertion.

The Coded Only data type flavour is used to carry this information as follows:

  • The code attribute will contain a one of the following codes from the Act Status vocabulary:
    • completed
    • nullified
[1..1] [M] templateId (II) { Fixed="COCD_TP146007UK04#LinkAssertion" }

The fixed value of this attribute provides a unique identifier for the template and the classname within that template.

The IdentifierExternal datatype flavour is used to carry this information as follows:

  • The root attribute shall contain the OID "2.16.840.1.113883.2.1.3.2.4.18.2"
  • The extension attribute shall contain the fixed value.
[0..1] author

Refers to the author of the link assertion.

This is the person who made the link between the two statements.

[1..1] [M] typeCode (CS {CNE:ParticipationType } ) { Fixed="AUT" }
Indicates that this is an author.
[1..1] [M] contextControlCode (CS {CNE:ContextControl } ) { Fixed="OP" }

Specifies how the author contributes to the context of the link assertion act and whether it may be propagated to descendent acts whose association allows such propagation.

"O" (Overriding)- the association replaces any context of the same or more specific type that has been conducted from the parent act.

"P" (Propagating)- the association is conducted to all child acts where the ActRelationship.contextConductionInd is set to "true."
[1..1] [M] contentId (II) { "NPFIT-000001#Role" }

This attribute, when valued in an instance, provides a unique forward pointing identifier for a template which constrains the classes and attributes which follow.

The attribute is intended simply as a structural navigational aid and should not be relied upon as an indicator of semantic meaning.

The IdentifierExternal datatype flavour is used to carry this information as follows:

  • The root attribute shall contain the OID "2.16.840.1.113883.2.1.3.2.4.18.16"
  • The extension attribute shall contain the template artifact Id.
[1..1] [M] functionCode (CV {CNE:AuthorFunctionType } ) { Fixed="OA" }

A code from the vocabulary shown indicating the function of the document author

The Coded Plain flavour of Coded Value (CV) datatype shall be used to carry this information as follows:

  • The code attribute shall contain the value
  • The codeSystem attribute shall contain the OID for the vocabulary concerned
  • The displayName attribute shall contain the text associated with the code
[1..1] [M] templateId (II) { Fixed="COCD_TP146007UK04#author" }

The fixed value of this attribute provides a unique identifier for the template and the classname within that template.

The IdentifierExternal datatype flavour is used to carry this information as follows:

  • The root attribute shall contain the OID "2.16.840.1.113883.2.1.3.2.4.18.2"
  • The extension attribute shall contain the fixed value.
