Next Steps for the Vocabulary Task Force
In several previous blogs, I've identified the availability of free vocabulary codesets/valuesets as a key enabler of interoperability.
The National Library of Medicine has produced the SNOMED-CT Core subset for problem lists, RxNorm for medication terms, and a LOINC subset for ordering labs.
To ensure the right subsets are available and maintained, we need governance - who decides what goes into the vocabularies, what mappings are created, and how disputes/redundancies are resolved? We need a place to store vocabularies that makes them easily accessible to all. We need a roadmap for future work.
The HIT Standards Committee's Vocabulary Task Force is holding three hearings. The first hearing on February 23 will focus on governance "rules of the road" for vocabularies. The second hearing, in March, will consider vocabulary infrastructure requirements. The next hearing will focus on end user needs for specific vocabularies included in meaningful use as well as future requirements. Additional hearings and meetings will be scheduled to address priority issues as they are identified.
The February 23 meeting will include three panels: (1) EHR vendors; (2) vocabulary service providers; and (3) vocabulary standards organizations.
Jamie Ferguson, who chairs the task force, has prepared useful background information for the hearing.
If you'd like to send advance comments about vocabulary governance as part of the hearing process, please send them to Judy Sparrow (firstname.lastname@example.org)
