NHS North West Genomics
2.2.0 - ci-build
NHS North West Genomics - Local Development build (v2.2.0) built by the FHIR (HL7® FHIR® Standard) Build Tools. See the Directory of published versions
| Actor | Definition |
|---|---|
| Requestor | A hospital laboratory that subcontracts a part of an Order or of an Order Group to another laboratory, e.g. Pathology or HODS. Is known in IHE LTW as Order Placer |
| Subcontractor | Receives Sub-orders, acknowledges specimen arrival and sends back results fulfilling these Sub-orders, e.g. Genomics. Is known in IHE LTW as Order Filler |
See Ref 1 for details.

Used by these Use Cases:
Used by these Use Cases:
The current IHE ILW specification relies on HL7 v2.x, HL7 v3, and IHE XDS. Several modernization paths are available, most of which focus on adopting FHIR, updating relevant IHE profiles, and shifting from Clinical Documents (HL7 CDA and FHIR Documents) to IHE QEDm for data exchange.
IHE ILW Modernisation with FHIR
See NHS England Genomic Order Management Service (GOMS) for the future use of the GOMS FHIR API to deliver sub-contracted orders (LAB-35) to, and receive results (LAB-36) from, other GMSAs.
See Haemato-Oncology Diagnostic Pathway for the CFT Shire → HODS-orchestrated reflex use case (pathology test order following on to a genomics test order, and the HODS-orchestrated haematological malignancy pathway), including the NHS North West Children Cancer notification example.
Variations on the basic LTW scenario.
Order Order Placer MUST include Ordering Facility (ODS Code) if the Order Filler is outside the organisation (i.e. ICS Pathology Lab or Regional Genomics Lab). Order Filler MUST respond with a Report Identifier and the Order Identifier (if supplied in the Order) in the laboratory report.

e.g. Haematology and oncology services
The specialty is responsible for sending a consolidated report to the Order Placer. For both the Pathology and Genomics Orders, the original Order Identifier SHOULD be included in the order (ServiceRequest.basedOn)

Is this around cancer? Is similar to above but both Lab and Genomics use the specimen for testing, so the genomic order is raised by the Pathology Lab.
Who has the responsibility for sending the genomic report to the Order Placer?
For the Reflex Order, the original Order Identifier SHOULD be included in the order (ServiceRequest.basedOn)

Genomic Lab sub contracts to another Genomics Lab for testing.
