TermInfo – Implementation Guide for Using SNOMED CT and LOINC Terminologies in HL7 Information Models

The new and expanded project officially began at the January 2012 WGM in San Antonio. The intent is to develop material for DSTU followed by normative ballot to address issues of overlap between the terminology and information models.

Download Terminfo Project Scope Statement

The links below are to the content from the previous DSTU standard (expired May 2009), which will serve as the starting point for our new work:

• Using SNOMED CT in HL7 Version 3; Implementation Guide, Release 1.5
  • "Wiki-fied version"
  • From May 2009 ballot package (HL7 members only)
• May 2009 TermInfo DSTU Ballot Reconciliation Package
  • Work on ballot reconciliation for the May 2009 DSTU was dropped for various reasons later in 2009 and was not completed. Following the launch of the new project in January 2012, this reconciliation work was re-started and was finally completed in May 2013 at the Atlanta WGM.

Hot Topics

• How to represent negation
• Considering changes in use of ASSERTION
• Discuss use of nesting in Problem Concern and Allergy Concern Acts
• Post-coordination
• Reporting negative assertions, ie No Growth, No Problems, No Results
• Use of NULL flavors
• Canonical sentences: a mechanism to reveal semantic meaning of coded clinical statements
• Terminology binding

Use Cases

Each use case needs to be given a meaningful name, then linked out to a page for that use case.

Presentations

Presentations given to explain TermInfo will be posted here.

Principles

A summary is posted here of the principles which form the basis upon which TermInfo is built.

TermInfo 1.5 DSTU - Update Project

This section of the wiki contains the content of the TermInfo, Release 1.5, broken into individual word documents. There is one document per chapter of the TOC. These files will be used to facilitate updating of the material from version 1.5 of the TermInfo Implementation Guide (Initially named, Using SNOMED CT in HL7 Version 3; Implementation Guide, Release 1.5) . Updates will be based on ballot comment reconciliations from the 2009 Ballot and other currently relevant improvements.
