Update on LOINC and RadLex Unification
Terminology Services to Reduce Avoidable CT Imaging F2F Meeting | 2015 10 14
Funding SupportContract from National Institute of Biomedical Imaging and Bioengineering
Phase 1: Computed Tomography Started Oct 2013, Ended September 2015
Some changes published in LOINC v2.52
More to be published in Dec LOINC release
Phase 2: All remaining modalities Funded by NIBIB effective 2015 10through 2017 09
Overall Goal:Produce a single unified source of names and codes for radiology procedures with a cooperative governance process.
Developing the Unified Radiology Model
Main DeliverablesDeveloping a Unified Model for Radiology Procedure Names
Mapping the attribute-values between each terminology (i.e. LOINC Parts to RadLex RIDs)
Mapping between RadLex RPIDs and LOINC codes
Unified Model Attribute Groupings “LOINC-speak”
ModalityMethod
Anatomy System
View Component†
Reason for Exam Component†
Guidance Component†
Pharmaceutical Challenge*
Subject Super System
* Currently no differentiation between chemical (contrast) and physical challenges † All part of the syntax used in creating the Component part name, but not labeled differently
A Users’ Guides for all attributes will be published as part of the LOINC Users Guide (coming in Dec 2015).

Governance
Recently Signed AgreementNew joint LOINC/RadLex Committee to be advisory body
LOINC codes as the primary identifier for radiology procedures (e.g. the universal codes) while linking to the RadLex attribute/values for each term so that they can be used as meta-data
Meetings at least once per year (open to public)
Distribution Artifacts
Distribution ArtifactsLOINC Table, RELMA (Regenstrief)
As is today
LOINC RSNA Playbook Table (Regenstrief) December 2015 LOINC release
Draft format as shown earlier
RadlLex Playbook Table (RSNA) Format determined by RSNA
New format for Version 2 (learned a lot from LOINC)
Includes “EXPORTED_TO_LOINC” attribute that points people to LOINC as we complete our work
A Few Summary StatsRPIDs mapped to LOINC: 104
