[[Encounter.Encounter ID]]

Encounter.extension

Running through each [[Encounter Event]] from oldest to newest, add one "specialty-history" extension as follows for each block of consecutive [[Encounter Event]]s with the same [[Data Point.Specialty]] (where "the same" means an exact, case-sensitive match of the specialty value).

• extension[0]: Extension

  • url =  "http://fhir.patientsknowbest.com/structuredefinition/specialty-history"

  • extension[0]

    • url = "specialty"

    • valueCoding: Coding

      • code = [[Data Point.Specialty]]

  • extension[1]

    • url = "period"

    • valuePeriod: Period

      • start = [[Encounter Event.Timestamp]] of the oldest encounter event within the block being represented

      • end = [[Encounter Event.Timestamp]] of the oldest encounter event within the block following the one being represented (if present)

Encounter.status

"unknown"

Encounter.class

• class: Coding

  • code = [[Encounter Event.Class]] of the most recent [[Encounter Event]] (as given by [[Encounter Event.Timestamp]])

  • system = "http://hl7.org/fhir/v3/ActCode"

[[Encounter Event.Class]] code mappings (PKB  →  FHIR):

• IN_PATIENT → IMP

• OUT_PATIENT → AMB

• AMBULATORY → AMB

• EMERGENCY → EMER

• HOME → HH

• FIELD → FLD

• DAYTIME → SS

• VIRTUAL → VR

• OTHER → omit value

Encounter.classHistory

Running through each [[Encounter Event]] from oldest to newest, add one entry to "classHistory" for each block of consecutive [[Encounter Event]]s with the same class value (where the class value is the FHIR value mapped from [[Encounter Event.Class]]). Do not add an entry if the value is OTHER.

• classHistory: BackboneElement

  • class: Coding

    • code = [[Encounter Event.Class]] of the block being represented (mappings as for Encounter.class)

    • system = "http://hl7.org/fhir/v3/ActCode"

  • period: Period

    • start = [[Encounter Event.Timestamp]] of the oldest encounter event within the block being represented

    • end = [[Encounter Event.Timestamp]] of the oldest encounter event within the block following the one being represented (if present)

Encounter.participant

Running through each [[Encounter Event]] from oldest to newest, add one entry to "participant" for each block of consecutive [[Encounter Event]]s with the same [[Encounter Event→External Participant]] (where "the same" means an exact, case-sensitive match of the participant name).

• participant: BackboneElement

  • type: CodeableConcept

    • coding[0]: Coding

      • system = "http://hl7.org/fhir/v3/ParticipationType"

      • code = [[Encounter Event→External Participant.Role]]

  • period: Period

    • start = [[Encounter Event.Timestamp]] of the oldest encounter event within the block being represented

    • end = [[Encounter Event.Timestamp]] of the oldest encounter event within the block following the one being represented (if present)

  • individual: Reference

    • display = [[Encounter Event→External Participant.Name]]

[[Encounter Event→External Participant.Role]] code mappings (PKB → FHIR):

• ATTENDER → ATND

• REFERRER → REF

• CONSULTANT → CON

Encounter.period

• period: Period

  • start = [[Encounter Event.Timestamp]] of the oldest encounter event

  • end = [[Encounter Event.Timestamp]] of the newest encounter event

Encounter.location

Running through each [[Encounter Event]] from oldest to newest, add one entry to "location" for each block of consecutive [[Encounter Event]]s with the same [[Encounter Event->Location]] (where "the same" means an exact, case-sensitive match of the location description).

The location should be added as a contained Location resource to the response...

• Location.description = [[Encounter Event->Location.Description]]

...and reference from the location list.

• location: BackboneElement

  • location: Reference

    • reference = a reference to the contained Location resource

  • period: Period

    • start = [[Encounter Event.Timestamp]] of the oldest encounter event within the block being represented

    • end = [[Encounter Event.Timestamp]] of the oldest encounter event within the block following the one being represented (if present)
