RELMA version 6.12

 

Mapping Feature Highlights

  • Enhanced the "Check the Test Names in Local Term File" and "Define Word Substitutions for Local Term Vocabulary" functions to support multi-word substitutions
  • Re-factored the "Define Word Substitutions for Local Term Vocabulary" to make it re-sizable
  • Filtering on user tags in the "View all Working Set" grid now supports a logical 'NOT' operator. This is a game-changer for the usefulness of tags!
  • Local terms can be mapped directly on the "View all Working Set Terms" grid
  • New "Comment" button on the mapping screen lets you add annotations, "notes to self", or other commentary about your mappings as needed.
  • New search restriction has been added to the "Hierarchy & Search Limits" screen:  Exclude non-routine challenge tests
    • For most users, this option will really help eliminate some unwanted clutter in your search results. 
    • Enabling this restriction will eliminate all tests in the CHAL class that are not in the CHAL.ROUTINE LOINC class from the search results
 

Content Feature Highlights

  • We have added two new columns in the data grid of the Answer List Search: "score" and "description"
  • The HIPAA attachments display has been modified to allow the user to view the version of C-CDA or CDP1 documents applicable to their use case
  • We have greatly enhanced the LOINC PART descriptions displayed in the "detail" pages
    • We have curated our catalog of descriptions to show the most relevant ones
    • We also enhanced the display to  include the PART name and a hyper-link to the "detail" page for the PART itself.  
  • We added a couple of new search fields available from the command line (see search help for more information)
    • CoreComponent
    • Supersystem 
    • Timemodifier
