Pathology FHIR Implementation Guide

WARNING

This guidance is under active development by NHS England and content may be added or updated on a regular basis. The implementation guide is currently in draft and SHOULD NOT be used for development or implementation without consulting the NHS England Pathology Standards and Implementation team.

Extensions

The UK Core extensions that are particularly relevant to pathology are summarised below.

For a detailed description of all of the UK Core extensions (including examples) refer to UK Core Implementation Guide - Profiles and Extensions - Extensions Index.

It should be noted the pathology related extensions are linked to pre-adopted FHIR R5 elements. For further information refer to UK Core Implementation Guide - Profiles and Extensions - Extensions Index - Pre-adopted R5 Elements.

Extension-UKCore-DiagnosticReportComposition

This extension allows a Reference to a Composition resource instance that provides structure for organizing the contents of the diagnostic report.

ExtensionUKCoreDiagnosticReportComposition (Extension)	I		Extension	Element id Extension Short description A Composition reference for a DiagnosticReport. Definition A Reference to a Composition resource instance that provides structure for organizing the contents of the DiagnosticReport. Data type Extension Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ext-1: Must have either extensions or value[x], not both `extension.exists() != value.exists()` Mappings rim: n/a rim: N/A
id		0..1	string	There are no (further) constraints on this element Element id Extension.id Short description Unique id for inter-element referencing Definition Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. Data type string Mappings rim: n/a
extension	I	0..*	Extension	There are no (further) constraints on this element Element id Extension.extension Short description Additional content defined by implementations Alternate names extensions, user content Definition May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Comments There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. Data type Extension Sliced: Unordered, Open, by url(Value) Extensions are always sliced by (at least) url Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ext-1: Must have either extensions or value[x], not both `extension.exists() != value.exists()` Mappings rim: n/a rim: N/A

ExtensionUKCoreSpecimenCollectionCollector (Extension)	I		Extension	Element id Extension Short description Person who collected the specimen. Definition Person who collected the specimen. Data type Extension Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ext-1: Must have either extensions or value[x], not both `extension.exists() != value.exists()` Mappings rim: n/a rim: N/A
id		0..1	string	There are no (further) constraints on this element Element id Extension.id Short description Unique id for inter-element referencing Definition Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. Data type string Mappings rim: n/a
extension	I	0..*	Extension	There are no (further) constraints on this element Element id Extension.extension Short description Additional content defined by implementations Alternate names extensions, user content Definition May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Comments There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. Data type Extension Sliced: Unordered, Open, by url(Value) Extensions are always sliced by (at least) url Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ext-1: Must have either extensions or value[x], not both `extension.exists() != value.exists()` Mappings rim: n/a rim: N/A
url		1..1	uriFixed Value	Element id Extension.url Short description identifies the meaning of the extension Definition Source of the definition for the extension code - a logical name or a URL. Comments The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension. Data type uri Fixed value http://hl7.org/fhir/5.0/StructureDefinition/extension-Specimen.collection.collector Mappings rim: N/A
value[x]		1..1		Element id Extension.value[x] Short description Person who collected the specimen. Definition Value of extension - must be one of a constrained set of the data types (see Extensibility for a list). Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a rim: N/A
