ScopeScopeIntegrate the clinical laboratory in the enterprise
Ordering, scheduling and performing clinical laboratory tests
Delivering the observation results to the medical staff, at various steps of validation.
All specialties working on specimen, not on the patient itself.
Anatomo-pathology and blood banks excluded
Sept 13-15, 2004 IHE Interoperability Workshop5
LSWF: Three major use casesLSWF: Three major use cases
Externally placed order with identified specimens The ordering provider collects the specimens and uniquely identifies them
(in the order sent in the message as well as on the container with a barcode label)
Externally placed order with specimens unidentified or to be collected by the laboratory
Filler order with specimens identified by the laboratory

LPOCT ScopeLPOCT ScopeSpecialties addressed:
Tests that can be performed on analyzers used on the point of care or
on patient’s bedside, under the supervision of a clinical laboratory
In vitro specimen testing
Tests on a specimen taken from the patient, not on the patient itself.
Tests that do not need pre-analytic processing of the specimen
Two general use cases:
Testing on a point of care device permanently connected to the
network
Testing on a point of care device periodically connected to the network

Laboratory Patient Information Laboratory Patient Information ReconciliationReconciliation
Match clinical lab observations produced on specimens collected from misidentified or unidentified patient with the patient’s record.
Match clinical lab observations produced on specimens with orders created afterwards, either in the Order Placer or in the Order Filler application.
