  1. Integrating the Healthcare Enterprise A new Profile for the Laboratory Domain: Laboratory Device Automation Francois Macary GWI Medica France Cochair IHE Laboratory Committee together with Yoshimitsu Takagi Hitachi Cochair IHE Laboratory Committee Noordwijkerhout, IHE Workshop

  2. Laboratory Device Automation (LDA) Work Order Steps LDA Demographics Demographics ADT Clinical Laboratory Placer order Order Placer Order Filler Filler order Work order Results Results Order Result Tracker Automation Manager LSWF Noordwijkerhout, IHE Workshop

  3. Scope of LDA Integration Profile • Workflow between an Automation Manager and the automated devices that it handles. • Workflow specimen based: A sequence of steps, each of which uses a specimen on a device. • Scope limited to devices operated by the lab staff. • Goal: To fulfill a Work Order and its clinical tests on the related specimens, using the various devices connected to the Automation Manager. • Except for the robotic transportation of the specimen, this profile does not address electromechanical command interface. Its transactions carry the needed or produced specimen related data back and forth between Automation Manager and Devices Noordwijkerhout, IHE Workshop

  4. Fulfillment of a Work Order • A Work Order is split into a sequence of steps according to the devices involved in its process. This sequence of steps includes three main phases: • the pre-analytical process of the specimens (sorting, centrifugation, aliquoting, transportation, decapping) • the analytical process (run of the clinical tests on the specimen) • the post-analytical process (recapping, transportation, rerun, dilution, storage and retrieval). Noordwijkerhout, IHE Workshop

  5. Example of workflow Perform electrolye Work Order for serum n° 123 Blood specimen Step 1: Convey to decapper Step 4: Query for test? Test Na, K, Cl Send the results Step 6: recap Step 2: decap centrifuging Step 5: Convey to recapper Step 3: Convey to chemistry analyzer Serum Schedules steps 1 to 6 Downloads steps 1, 2, 3, 5, 6 Automation Manager Chemistry Analyzer decapper recapper Robotic Specimen Transportation System Noordwijkerhout, IHE Workshop

  6. Main use cases (1) • Step downloaded on the device before specimen arrival Automated Device Automation Manager Work Order received from Order Filler Step Download Specimen recognized Step Status Change: Specimen arrived Step completed Step Status Change: Step complete Noordwijkerhout, IHE Workshop

  7. Main use cases (2) • Step query triggered by specimen recognition on device Automated Device Automation Manager Work Order received from Order Filler Step scheduled Specimen recognized Step Query (What must I do with this specimen?) Step completed Step Status Change: Step complete Noordwijkerhout, IHE Workshop

  8. Main use cases (3) • Step manually entered on the device Automated Device Automation Manager Work Order received from Order Filler Step scheduled and printed out Specimen recognized Step entered and started Step completed Step Status Change: Step complete Noordwijkerhout, IHE Workshop

  9. Main use cases (4) • Rerun can be decided at different times • Decided on the device immediately after obtention of the first results. E.g. Results out of scale  Rerun with dilution • Decided by the laboratory staff during the technical validation of the first results, using the Automation Manager application • Decided by the laboratory clinical expert during the clinical validation of the first results, using the Order Filler application Noordwijkerhout, IHE Workshop
