ObservationMedia

A template to allow attachments to be carried in a CDA document.

This class is a derivative of the RIM Observation class that represents multimedia that is logically part of the current document. This class is only for multimedia that is logically part of the attested content of the document. Rendering ObservationMedia requires a software tool that recognizes the particular media (MIME) type.

Used by:
[1..1] [M] classCode (CS { CNE: ActClass } )
{ Fixed="OBS" }

Model Attribute Description

The HL7 attribute classCode uses a code to describe this class as an observation.

Implementation in XML Instance

The XML attribute classCode is fixed to " OBS ".
[1..1] [M] moodCode (CS { CNE: ActMood } )
{ Fixed="EVN" }

Model Attribute Description

The HL7 attribute moodCode uses a code to describe this class as an observation event.

Implementation in XML Instance

The XML attribute moodCode is fixed to " EVN ".
[1..1] [M] id (II)

Model Attribute Description

The HL7 attribute id uses an identifier that uniquely identifies this instance of an attachment.

Implementation in XML Instance

The Identifier Global data type flavour is used to carry this information in the XML element id as follows:

  • The XML attribute root shall contain a DCE UUID.
[1..1] [M] templateId (II)
{ Fixed="COCD_TP146002GB01#ObservationMedia" }
Model Attribute Description

The HL7 attribute templateId provides a unique identifier for the template and the classname within that template. This is used to identify how the CDA standard has been constrained for NHS use.

Implementation in XML Instance

The Identifier External data type flavour is used to carry this information in the XML element templateId as follows:
  • The XML attribute root is fixed to the OID " 2.16.840.1.113883.2.1.3.2.4.18.2 "
  • The XML attribute extension is fixed to " COCD_TP146002GB01#ObservationMedia "
[1..1] [M] value (ED)

Model Attribute Description

The HL7 attribute value is used to allow attachments to be carried in a CDA document.

Implementation in XML Instance

The ED (encapsulated data) data type is used to carry this encapsulated data in the XML element value. The XML element value should be populated as follows:
  • The XML attribute mediaType of the XML element value identifies the MIME type of the encapsulated data.
  • The XML attribute representation of the XML element value identifies the representation of the encapsulated data.
    • The representation is either " B64 " for Base 64 Encoding or " TXT " for all other representations.
[1..1] [M] participant
This class is a participant of device. It is used to hold details of the name and version of the sofware used to capture a NHS111 triage.
[1..1] [M] typeCode (CS { CNE: ParticipationType } )
{ Fixed="DEV" }

Model Attribute Description

The HL7 attribute typeCode uses a code to describe this class as a device participation.


Implementation in XML Instance

The XML attribute classCode is fixed to " DEV ".

[1..1] [M] contextControlCode (CS { CNE: ParticipationContextControl } )
{ Fixed="OP" }

Model Attribute Description

The HL7 attribute contextConductionCode uses a set of codes from the HL7 vocabulary ContextControl to determine whether participations associated with the parent section is conducted across to the child section (also associated with the child section). This set of codes also determine how these participations conduct.

The conduction can only take place if the contextConductionInd is set to " true ".

The value of this attribute is fixed in the HL7 model to " OP ":

  • " O " (Overriding)- the author replaces any author that has been conducted from any previous acts.
  • " P " (Propagating)- the author is conducted to all child acts where the contextConductionInd is set to " true ".


Implementation in XML Instance

The XML attribute contextControlCode shall contain the fixed value " OP ".

[1..1] [M] contentId (II) { "NPFIT-000087#Role" }

Model Attribute Description


The HL7 (NHS localisation) attribute contentId, when valued in an instance, provides a unique forward pointing identifier for the template which constrains the classes and attributes which follow, for NHS use.

The attribute is intended simply as a structural navigational aid and should not be relied upon as an indicator of semantic meaning. The contentId is populated at runtime with a value from the allowed list contained in the model.

Implementation in XML Instance

The Identifier External data type flavour is used to carry this information in the XML element contentId as follows:

  • The XML attribute root is fixed to the OID " 2.16.840.1.113883.2.1.3.2.4.18.16 "
  • The XML attribute extension shall contain one of the allowed template artefact identifiers.
[1..1] [M] templateId (II)
{ Fixed="COCD_TP146002GB01#participant" }
Model Attribute Description

The HL7 attribute templateId provides a unique identifier for the template and the classname within that template. This is used to identify how the CDA standard has been constrained for NHS use.

Implementation in XML Instance

The Identifier External data type flavour is used to carry this information in the XML element templateId as follows:

  • The XML attribute root is fixed to the OID " 2.16.840.1.113883.2.1.3.2.4.18.2 "
  • The XML attribute extension is fixed to " COCD_TP146002GB01#participant "
[1..1] [M] participant (DeviceChoice)
A link to the choice of device templates.
DeviceChoice
An abstract placeholder for the templates for a device.
