Status

This is not shown explicitly, but is included in the logic which determines if the medication is current or past.

status

status code mappings (FHIR → PKB):

• active → ACTIVE

• unknown → ACTIVE

• on-hold → INACTIVE

• cancelled → INACTIVE

• completed → INACTIVE

• entered-in-error → INACTIVE

• stopped → INACTIVE

• draft → INACTIVE

• unknown → ACTIVE

Substance

The medication substance is shown in 2 places:

• A primary display string. This is a simple display string shown in the unexpanded row view.

• Additional details. Information about the medication code and system values are shown in the expanded row view.

<conditional>

If medicationReference is populated:

(Note: Medication is a merged resource type; the merge logic affects the content of the resource.)

Primary display string

• If code.text is populated: the same text

• else: the last populated code.coding[x].display

• else: the empty string

Additional details

The code and system of all code.coding Codings are shown. Other elements of the Coding are not shown.

Note: the system will be replaced with user-friendly name when known to PKB.

Else:

Primary display string

• If medicationCodeableConcept.text is populated: the same text

• else: if a Coding is present and contains the http://fhir.patientsknowbest.com/structuredefinition/primary-coding extension: the display of the same Coding

• else: the first populated medicationCodeableConcept.coding[x].display

• else: the empty string

Additional details

As per the logic above for primary display string.

Start Timestamp

<conditional>

If this extension is present: http://nictiz.nl/fhir/StructureDefinition/zib-Medication-PeriodOfUse

extension[x]: valuePeriod.start

Else:

authoredOn

effectivePeriod.start

End Timestamp

<conditional>

If this extension is present: http://nictiz.nl/fhir/StructureDefinition/zib-Medication-PeriodOfUse

extension[x]: valuePeriod.end

Else:

No value.

effectivePeriod.end

For the dosage and frequency-related information, except where noted PKB will use the Primary Dosage, which is the Dosage determined as follows:

• Determine which Dosage list to inspect

  • If the resource is a MedicationRequest: then use dosageInstruction

  • Else if the resource is a MedicationStatement: then use dosage

• The select 1 Dosage from the list as follows:

  • If there is exactly one Dosage where sequence is 1, then use the same

  • Else: use the first in the list

“Structured Frequency”

(Frequency Priority / Frequency Value / Frequency Units)

<conditional>

If asNeededCodeableConcept is present, or asNeededBoolean is set to true:

“Take as needed” will be shown; i18n is applied.

Else if Timing.code is populated with any value:

“Take as directed” will be shown; i18n is applied.

Else if Timing.repeat has frequency set to 1, periodUnit has a value of either “d” or “h”, and period is a known integer for the corresponding periodUnit:

A corresponding textual description; i18n is applied.

Example: “Every four hours”

Else:

No value.

Frequency Text

This is shown underneath the main line for the medication.

<conditional>

If text is populated: the same text

Else if there was no Structured Frequency found, and Timing.repeat is populated with both period and periodUnit:

If frequency element is also populated:

“<frequency> time(s) every <period> <periodUnit>(s)” will be generated and shown; i18n is not applied.

Else:

“Every <period> <periodUnit>(s)” will be generated and shown; i18n is not applied.

Else:

No value.

Dose Value

doseAndRep[0].doseQuantity.value

Dose Units / Medication Unit

The dose unit is shown in 2 places:

• A primary display string. This is a simple display string shown in the unexpanded row view.

  • Note: this is only displayed if Dose Value is populated.

• Additional details. Information about the dose unit code and system values are shown in the expanded row view.

<conditional>

If doseAndRep[0].doseQuantity has a code, no unit and no system:

The code is assumed to be one of the supported unit values as per [[Medication Unit]].

Primary display string

The primary display string will be an appropriate display name with i18n applied.

Additional details

There is no additional code information to display.

Else:

We inspect the first Dosage (which might differ from the previously determined Primary Dosage) and inspect doseAndRep[0].doseQuantity for the http://fhir.patientsknowbest.com/structuredefinition/dose-units extension.

Primary display string

• If text is populated: the same text

• else: if a Coding is present and contains the http://patientsknowbest.com/structuredefinition/primary-coding extension: the display of the same Coding

• else: the first populated coding[x].display

• else: the empty string

Additional details

The code and system of all Codings are shown. Other elements of the Coding are not shown.

Note: the system will be replaced with user-friendly name when known to PKB.

Instructions

The instructions displayed will be the concatenation of all of the following information, in this order:

• Dosage.patientInstruction

• Each Dosage.additionalInstruction[x].text value
