eDOS Summary – Background • eDOS: Provides an electronic interchange of a laboratory’s

Directory of Services (DOS) in a structured format based on HL7’s 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 Association’s (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 HL7’s 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.

Background

• eDOS, or the Laboratory Test Compendium Framework, provides an electronic interchange of a laboratory’s directory of services in a structured format based on HL7’s 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 don’t delay the LOI Initiative, the Tiger Team decided to spin off a separate eDOS Work Group to focus on eDOS

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 HL7’s 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

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 download– Incorporates previously reviewed

change requests and edits to synch with LRI/LOI• 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

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.

eDOS IG Project Update

Ask at Order Entry (AOE) Appendix A– V12 posted, incorporates edits from Peer

Reviews– LOI Vocabulary meeting weekly to resolve
