Meeting Etiquette• Remember: If you are not speaking keep your phone on mute• Do not put your phone on hold – if you need to take a call, hang up

and dial in again when finished with your other call • This meeting, like all of our meetings, is being recorded

– Another reason to keep your phone on mute when not speaking!• Feel free to use the “Chat” or “Q&A” feature for questions or

comments• Please announce your name each time prior to making comments or

suggestions during the Q&A portion of the meeting

NOTE: This meeting may be recorded and, if recorded, will be posted on the eDOS wiki

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 2.6. 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

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 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 UpdateIG updates in progress:

– Deleted HL7 content to synch with LOI/LRI style convention

– Adding the following:• approved errata/change requests• data type section, synched with LOI and LRI• “pre-adopt” notes, e.g. V2.8 approved

proposals, and select V2 data types (synch with LOI/LRI)
