Laboratory Scheduled Workflow Abstract / Scope Spans ordering, conformity of specimens, lab automation, results delivery. Handles all major types of workflows: – Externally placed order with identified specimens – Externally placed order with specimens unidentified or to be collected by the laboratory – Internally placed order with specimens identified by third party or collected by the laboratory Shares ADT transactions with Radiology

Laboratory Scheduled Workflow Value Proposition A comprehensive workflow approach – Spans all countries – Address specimen linkage – most lab specialties: Blood gases, Chemistry, Hematology, Immunology, Laboratory, Microbiology, Mycobacteriology, Mycology, Serology, Toxicology, Virology. Provides workflow improvement – Increases continuity and integrity of clinical data – Decreases user need for manual tasks.

Laboratory Scheduled Workflow Key Technical Properties Standard Used : HL7 V2.5 – Released 2003 – Includes significant extensions developed by HL7 UK and Germany for specimen tracking – Leverages broad acceptance world-wide of HL7 V2 – Offers the option to support HL7V2-XML IHE Integration Profile value-add: – A robust data model supporting all necessary workflow concepts. – Offers a significant improvement over V2.3 for a reasonable incremental effort.
