Trial.gif Internal References

CDA and HL7 Version 3 Entries may reference (point to) information contained in other entries within the same document or message as shown below.


See Templates using Internal References

Internal References Example
  <entryRelationship typeCode='' inversionInd='true|false'>
      <act classCode='' moodCode=''>
        <templateId root=''/>
        <id root='' extension=''/>
        <code code='' displayName='' codeSystem='' codeSystemName=''/>

<entryRelationship typeCode=' ' inversionInd='true|false'>

For CDA the act being referenced appears inside a related entryRelationship. The type (typeCode) and direction (inversionInd) attributes will be specified in the entry content module that contains the reference. For HL7 Version 3 Messages, the relationship is indicated with a <sourceOf> element, however typeCodes and semantics remain unchanged.

<act classCode=' ' moodCode=' '>

The act being referred to can be any CDA Clinical Statement element type (act, procedure, observation, substanceAdministration, supply, et cetera). For compatibility with the Clinical Statement model the internal reference shall always use the <act> class, regardless of the XML element type of the act it refers to.

<templateId root=''/>

The <templateId> element identifies this as an internal reference that conforms to all rules specified in this section.

<id root=' ' extension=' '/>

This element shall be present. The root and extension attributes shall identify an element defined elsewhere in the same document.

<code code=' ' displayName=' ' codeSystem=' ' codeSystemName=' '/>

This element shall be present. It shall be valued when the internal reference is to element that has a <code> element, and shall have the same attributes as the <code> element in the act it references. If the element it references does not have a <code> element, then the nullFlavor attribute should be set to "NA".
