Grouping of zero, one or more Observations/Observation components

Observation

Per Observation (or Observation and Observation.component)

/ClinicalDocument/component/structuredBody/component[2]/section/entry/organizer/component/observation/

Observation.identifier

(if an Observation.identifier has a system resolvable to OID type)

• Measurement id

/ClinicalDocument/component/structuredBody/component[2]/section/entry/organizer/component/ovservation/id

id@extension is set to Observation.identifier.value.

id@root is set to OID value resolved from Observation.identifier.system.

Resolving as OID type system is either (in order):

• Observation.identifier.system prefixed with urn:oid:

• Observation.identifier.system can be matched to FHIR NamingSystem (in terminology service) which has NamingSystem.uniqueId.value where uniqueId.type is oid

A random UUID

(Observation.identifier has no system resolvable to OID type)

id@extension is set to random UUID

id@root is set to "1.2.208.176.7.200.1" (which is OID type in https://docs.ehealth.sundhed.dk/latest-released/igfhir/NamingSystem-ehealth-identifier.html )

Observation.effective[x]

• Measurement time

/ClinicalDocument/component/structuredBody/component[2]/section/entry/organizer/effectiveTime

Start date of observation.

If Observation.effective is a Period, the Period.start value is used if present, otherwise it is set to the Period.end.

If Observation.effective is a DateTime or InstantType the value is used.

Observation.code

• Measurement type

/ClinicalDocument/component/structuredBody/component[2]/section/entry/organizer/component/observation/code

SNOMED CT system with value set to nullFlavor.

/ClinicalDocument/component/structuredBody/component[2]/section/entry/organizer/component/observation/code/translation

Observation.valueQuantity

• Measured value, unit

/ClinicalDocument/component/structuredBody/component[2]/section/entry/organizer/component/observation/value

Value and unit in percent are converted to unitless decimals (fraction).

Observation.performer

• Measurement Method and Measured By (MethodCode)

/ClinicalDocument/component/structuredBody/component[2]/section/entry/organizer/component/observation/methodCode

The details for deciding the two method codes can be found in the table below.

Observation.quality

Observation.referenceRange

• Reference Range

/ClinicalDocument/component/structuredBody/component[2]/section/entry/organizer/component/observation/referenceRange

As mentioned above, the PHMR reference ranges are inverted ranges compared to the fhir format, so we need to invert the ranges when transforming to fhir. If a yellow range is present we check if there is also a red range, if so we map the yellow range to an interval between the start of the yellow range and the start of the red range. Otherwise, the ranges are open-ended.

If the reference ranges are exclusive we encode this in fhir by subtracting or adding a small constant. For the same reason, we are not able to handle values with more than 7 decimals. So we check if any referenceRange value has more than 7 decimals and if that is the case we throw an exception and stop the translation.

Observation.note

Observation.note.authorReference (referencing a Practitioner or Organization)

Comment on observation

/ClinicalDocument/component/structuredBody/component/section/entry/organizer/component/observation/entryRelationship/act

An entryRelationship is added to the observation with LOINC code for Annotation comment (code=48767-8, codeSystem=2.16.840.1.113883.6.1).

The author of the note is mapped like Author Organization and/or Author Individual, depending on Observation.note.authorReference.
