List (Consultation) Mapping

XML HL7 > JSON FHIR

A List (Consultation) is created from mapped Encounters.
Where the EHR extract is used it is the root EhrExtract of the XML. Where EhrComposition is used, it refers to the EhrComposition used to construct the Encounter
This is a top-level profile and represents the whole structured consultation

Mapped to (JSON FHIR List field) Mapped from (XML HL7 / other source)
id ehrComposition / id \[@root] suffixed with -CONS
meta.profile[0] fixed value = "https://fhir.nhs.uk/STU3/StructureDefinition/CareConnect-GPC-List-1"
status fixed value = current
mode fixed value = snapshot
title ehrComposition / code [@displayName] or ehrComposition / code / originalText or found by searching the adaptors SNOMED database for the appropriate description when Encounter is mapped.
code.coding[0].system fixed value = http://snomed.info/sct
code.coding[0].code fixed value = 325851000000107
code.coding[0].display fixed value = Consultation
subject this a reference to the mapped Patient from the encounter
date ehrComposition / effectiveTime / center or EhrComposition / effectiveTime / low or ehrComposition / availibiltyTime
orderedBy.coding[0].system fixed value = http://hl7.org/fhir/list-order
orderedBy.coding[0].code fixed value = system
orderedBy.coding[0].display fixed value = Sorted by System
encounter reference to mapped Encounter
entry[index].item.reference reference to one or more mapped List (Topic)

The following List fields are not currently populated by the adaptor:

  • identifier
  • source
  • note
  • entry.flag
  • entry.deleted
  • entry.date

JSON FHIR > XML HL7

A List (Consultation) does not generate its own XML section but instead is used to identify which Topics will be used to retrieve the components used when mapping an Encounter.

Mapped to (XML HL7 Encounter) Mapped from (JSON FHIR / other source )
EhrComposition / Component [@typeCode="COMP"]` resource when the list contains a reference to Encounter.id and 'resource.resourceType=List` 1
  1. For each reference in resource.entry.item.reference, the resultant topic list are parsed and the mapped Components are inserted into the XML.
Example XML 
<component typeCode="COMP">
    <ehrComposition classCode="COMPOSITION" moodCode="EVN">
        <id root="46DDDE45-9CA1-485A-9789-2C342D33CEE3" />

        <statusCode code="COMPLETE" />
