Slice examples in XML

This page provides guidance on how slicing is expected in R4 profiles that are created by Nictiz. Examples are provided in XML format but could have been in JSON format as well.

Slice definition to specify 1 or more variations of a concept.

The FHIR:Identifier element is sliced to provide the definition one specific identifier.

<element id="Patient.identifier">
    <path value="Patient.identifier"/>
    <slicing>
        <discriminator>
            <type value="value"/>
            <path value="$this"/>
        </discriminator>
        <rules value="open"/>
    </slicing>
</element>
<element id="Patient.identifier:BSN">
    <path value="Patient.identifier"/>
    <max value="1" />
    <patternIdentifier>
        <!--<use value="official"/> -->
        <system value="http://fhir.nl/fhir/NamingSystem/bsn"/>
    </patternIdentifier>
</element>

Slice definition that combines the use of a semantic code and a HCIM concept.

<element id="Observation.category">
    <path value="Observation.category" />
    <slicing>
        <discriminator>
            <type value="value" />
            <path value="$this" />
        </discriminator>
        <rules value="open" />
    </slicing>
    <min value="1" />
</element>
<element id="Observation.category:laboratoryTestResultCode">
    <path value="Observation.category" />
    <sliceName value="laboratoryTestResultCode" />
    <min value="1" />
    <max value="1" />
    <patternCodeableConcept>
        <coding>
            <system value="http://snomed.info/sct" />
            <code value="49581000146104" />
        </coding>
    </patternCodeableConcept>
</element>
<element id="Observation.category:ResultType">
    <path value="Observation.category" />
    <sliceName value="resultType" />
    <max value="1" />
    <binding>
        <strength value="required" />
        <description value="ResultaatTypeCodelijst" />
        <valueSetReference>
            <reference value="http://decor.nictiz.nl/fhir/ValueSet/2.16.840.1.113883.2.4.3.11.60.40.2.13.1.1--20171231000000" />
            <display value="ResultaatTypeCodelijst" />
        </valueSetReference>
    </binding>
</element>

Slice definition to specify the datatype(s) of the element.

<element id="Observation.value[x]">
    <path value="Observation.value[x]"/>
    <slicing>
        <discriminator>
            <type value="type"/>
            <path value="$this"/>
        </discriminator>
        <rules value="open"/>
    </slicing>
</element>
<element id="Observation.value[x]:valueCodeableConcept">
    <path value="Observation.valueCodeableConcept"/>
    <sliceName value="valueCodeableConcept"/>
    <type>
        <code value="CodeableConcept"/>
    </type>
</element>
<element id="Observation.value[x]:valueQuantity">
    <path value="Observation.valueQuantity"/>
    <sliceName value="valueQuantity"/>
    <type>
        <code value="Quantity"/>
    </type>
</element>

Slice definition to allow multiple ValueSet bindings.

Note: only applies in rare circumstances when different requirements are present for each ValueSet.

<element id="Procedure.code.coding">
    <path value="Procedure.code.coding"/>
    <slicing>
        <discriminator>
            <type value="value"/>
            <path value="$this"/>
        </discriminator>
        <rules value="open"/>
    </slicing>
</element>
<element id="Procedure.code.coding:verrichtingTypeCodelijst">
    <path value="Procedure.code.coding"/>
    <sliceName value="verrichtingTypeCodelijst"/>
    <binding>
        <strength value="required"/>
        <description value="The name of the procedure using the Verrichtingenthesaurus DHD."/>
        <valueSet value="http://decor.nictiz.nl/fhir/ValueSet/2.16.840.1.113883.2.4.3.11.60.40.2.14.1.2--20171231000000"/>
    </binding>
</element>

Slice definition for multiple mapped concepts to one element that are discriminated by their conformance to a profile.

Note: try to avoid profile type discriminators as they are more costly to perform by a validator. This slicing definition is discriminated based on the conformance of the target resource to a profile. In this case, the path needs to include the resolve() function to indicate to the validator that is should resolve the reference.

<element id="DiagnosticReport.result">
    <path value="DiagnosticReport.result" />
    <slicing>
        <discriminator>
            <type value="profile" />
            <path value="resolve()" />
        </discriminator>
        <rules value="open" />
    </slicing>
    <max value="1" />
</element>
<element id="DiagnosticReport.result:measurementValue">
    <path value="DiagnosticReport.result" />
    <sliceName value="measurementValue" />
    <max value="1" />
    <type>
        <code value="Reference" />
        <targetProfile value="http://nictiz.nl/fhir/StructureDefinition/zib-GeneralMeasurement" />
    </type>
</element>
<element id="DiagnosticReport.result:healthCondition">
    <path value="DiagnosticReport.result" />
    <sliceName value="healthCondition" />
    <max value="1" />
    <type>
        <code value="Reference" />
        <targetProfile value="http://nictiz.nl/fhir/StructureDefinition/zib-FunctionalOrMentalStatus" />
    </type>
</element>
