3. eDOS Summary – Background eDOS: Provides an electronic interchange of a laboratorys Directory of Services (DOS) in a structured format based on HL7s master file update found in Chapter 8 of version 2.5.1. This implementation guide, initially developed by the members of the American Clinical Laboratory Associations (ACLA) in conjunction with their Health Information Technology (HIT) Committee, is intended to provide all necessary information to help an Ordering Provider properly request laboratory tests consistent to aide patient diagnosis. The eDOS work effort will: –Validate that the current Informative Implementation Guide meets the objective through a pilot of eDOS –Align the IG with the in-scope tests in the Lab Result Interface (LRI) IG –Incorporate pilot findings to update the Implementation Guide to develop a normative document to be balloted based on HL7s ANSI process. –The Normative IG is intended to support the efforts of the Lab Order Interface (LOI) IG and the Lab Result Interface (LRI) IG by providing the services necessary to meet the needs of the users of those guides.

4. Background eDOS, or the Laboratory Test Compendium Framework, provides an electronic interchange of a laboratorys directory of services in a structured format based on HL7s master file update. –An Implementation Guide was developed by the members of the American Clinical Laboratory Association (ACLA) in conjunction with their Health Information Technology (HIT) Committee to provide all necessary information to help an Ordering Provider properly request laboratory tests consistent to aide patient diagnosis. –The eDOS IG is available as an informative document from HL7 The LOI Tiger Team identified the importance of coordinating the LOI and eDOS efforts so that LOI can validate the eDOS IG as part of the LOI alignment activities To ensure that the eDOS efforts dont delay the LOI Initiative, the Tiger Team decided to spin off a separate eDOS Work Group to focus on eDOS 4

5. Background The initial work group efforts outlined focus on kicking off pilots to validate the Implementation Guide with the goal of creating a normative document to be balloted based on HL7s ANSI process To ensure successful validation and pilots, a Use Case and Functional Requirements will be developed to validate existing industry requirements and the current informative IG –Real-world scenarios will help create specific pilot test conditions and metrics for use in Pilot validation of the IG –Clearly defined functional and data set requirements facilitate eDOS & LOI coordination and alignment –A well-articulated Use Case supports awareness of the clinical and implementer communities real-world needs 5

6. Pilot Updates Quest Diagnostics –Working to Find a Partner and Site LabCorp –Initial Contact Bioreference Labs –Not able to Participate Mayo –Request for Pilot Submitted; approved 4/9 Genoptix –Request for Pilot Submitted; approved 4/23 Kaiser Permanente –Initial Contact ARUP –Unable to Contact

7. eDOS IG Project Update Ballot delayed due to AOE appendix additions –Release 2 IG (v9) draft posted on wiki; may have to complete IP form to downloadv9 –Incorporates previously reviewed change requests and edits to synch with LRI/LOIchange requests Release 2 Conventions –Pre-adopts, data type flavors, conformance statements –RE ( Required but may be empty) if ACLA field note or V2.8 pre-adopt

8. eDOS IG Project Update New Change Request # OO_CR_132-752 http://wiki.hl7.org/index.php?title=OO_CR132- 752_M10_Usage_eDOS Correct M10 - Master File Notification – Test/Observation Batteries usage in R1 of eDOS IG to change usage for the Test Battery Detail section (containing OM5 and OM4 segments) from required and repeating to optional and not repeating to sync with V2.5.1 and V2.6 standard. eDOS R1 was developed using HL7 V2.6, but R2 is based on V2.5.1.
