Co-Chair Orders/Observations – HL7
Co-Chair LRI IG Work Group
Standards and Interoperability
Framework The Laboratory Results Interface Works in Consert with HL7
Defines Additional Message Constraints
"Plug and Play" Interfaces
Unique Identifiers called OIDs in MHS.21
Defines Test Order/Observation Linkage
Snap Shot Mode
Latest update October 10, 2012 Standards for Interoperability Conference Focus:
Meaningful Use Stage 2 and 3
Trip Purpose:
Visit InterSystems
Ensemble & Cache
Visit LIS Venders
Barcode Imagers / RFID Readers
Slide Label Printers
All-in-one Computers The Laboratory Results Interface
( LRI ) IHE – Integrating the Healthcare Enterprise
Aims to provide standardized interfaces for data exchange between health care vendors based on the HL7 and DICOM.
Global intent, not US specific

HITSP – Healthcare Information Technology Standards Panel
Partnership between the public and private sectors to harmonize integrating standards that will meet clinical needs.
Too big a step for many laboratories

ELINCS – Lab Data Standard for Electronic Health Records
Interoperability and Connectivity Specification for standarding the formatting and coding of messages between laboratories and electronic health record (EHR) systems
US and California focus, too strict for most laboratories A number of laboratory results
laboratory results interface standards:
IHE
HITSP
ELINCS
Need “best of all worlds”

XML Based Encoding
Reference Information Model (RIM)
Act - Something that has or may happen
Entity - Any living or non-living thing
Role - Entity plays a role HL7 34,696 total attendees
1,158 exhibiting companies ` HL7 International Working Group Meeting
DICOM
Digital Imaging and Communications in Medicine
Binary Data Structure
Contains Image and Meta Data
Supports Multi Part Encoding
Used to Interface with PACS
Picture Archiving and Communication Systems CDA CDA - Release 2.0
Clinical Document Architecture,
Standard Markup for Clinical Document
Complete Document Exchange & Archive
XML Based Encoding
Persistence – Document Exist Unaltered
Stewardship – Maintained by Trusted Organization
Potential for Authentication - A Legal Assemblage
Context - Provides Context for Content.Wholeness - Contains the Entire Document
Human Readability – A Readable Clinical Document LOINC LOINC Codes
Standard Classification of Observables
Clinical Laboratory Tests - not Results
Clinical Observables - "Eye Color", not "Blue Eyes"
Consecutive Number + Check digit e.g. 12345-9
Short Convenient Name w/ Long Common Name
Completely Free - Easy to Add New Codes

SNOMED CT
Standard Classification of Observables and Result
Good for Observation Values Too
Codes Have Hierarchy
LOINC and SNOMED are Complementary
