From IHE Wiki
Jump to: navigation, search
This profile is part of the Pathology and Laboratory Medicine (PaLM) domain, which merged the former AP and LAB domains since 2016, January 4th.

Inter Laboratory Workflow (ILW) supports the workflow of orders and results of in vitro diagnostic tests between a requesting laboratory and a subcontracting laboratory.



Summary

The Inter-Laboratory Workflow Profile covers the workflow of orders and results beween a requesting lab providing the specimens and the orders and a subcontracting lab performing the tests and reporting the results to the former one. This workflow is able to carry the payors information along with the order (patient insurances, guarantor, ...). The structured results may be accompanied by a pdf copy of the performing lab report.

Details

The Inter-Laboratory Workflow (ITW) Integration Profile is bound to in vitro diagnostic testing. The specimen is always provided by the requesting lab. The subcontracting lab does not see the patient. This profile supports all laboratory specialties but anatomic pathology.

Use cases:
The ILW Integration Profile covers three major use cases:

  • Cooperation between a hospital and a specialized private laboratory
  • Specific tests subcontracted to a national reference laboratory
  • Distributed process in a cooperative group of laboratories

Transactions:
ILW Integration Profile defines 2 Transactions: LAB-35 "Sub-order management" and LAB-36 "Sub-order results delivery". Both transactions are based on HL7 release 2.5.1 messaging standard. LAB-35 is implementing an OML/ORL message pair. LAB-36 is implementing an ORU/ACK message pair.

Systems Affected

Systems involved in this profile are the laboratory informations systems (LIS) of the requesting lab and the subcontracting lab, messaging with one another.
