New Features 12.03.2007

New LOINC Content

LOINC version 2.22 contains 50,809 terms, an increase of 2,209 since the June 2007 version. Approximately 500 terms have been edited.  A total of 1,359 terms have been deprecated.

Several unused or obsolete fields have been removed from this version of the database. The collection of fields that stored mappings to related codes, example units of measure, and our earliest foreign language translations have been migrated out of the main LOINC table and are now stored in a more structured format within the RELMA.mdb database. In summary, there are now 43 fields in LOINC.mdb, instead of 63.  Please see Appendix A of the LOINC User's Guide (LOINCManual.doc) for more information on the structure of the database.

New RELMA Functions

1. Translation of parts and synonyms are now displayed in the detail screens.
2. Options available on the context menus (right click menus) of the grids are now consistent thought the application.
3. Users can now control which columns of data get saved when exporting data from the various grid controls. To use this feature, look for the "Columns to Export" button on the bottom of most grids.
4. The Common Tests restriction was restructured so you can only select a single common test restriction at a time.
5. The structured details display has been removed. All LOINC and part detail display now use the newer HTML display format.
6. From the Panels, Forms & Surveys screen, you can now enter a list of LOINC codes and RELMA will return a list of the panels or forms that  contain those LOINC codes.
7. The LOINC detail displays now shows unit information that was submitted by various hospitals and organizations. 
8. RELMA now contains links to reference information on the internet.  To access this information from RELMA, you must have an open connection  to the internet while you are using the program.
9. LOINC and Part reference information is now divided up into articles, citations, descriptions, original form links, package inserts, and technical briefs.
10. RELMA output file names now follow a more consistent naming convention, where all RELMA output filenames start with "RELMA_". RELMA now defaults to the "My Documents" directory for all Save File dialogs.
11. The main mapping screen can display search results in as either a flat list or in a tree structure. Unfortunately, the tree structure doesn't currently contain all of the available LOINC codes. This makes it possible to execute a search which returns LOINC codes that can be displayed in a list, but not available in the tree. If this situation occurs, a message will be displayed and the display will automatically revert to the flat list style of display. NOTE - There are plans to  fully populate the tree structure in future releases of LOINC.
12. All Save to File actions now save in Comma-Separated-Value (CSV) format.
13. You do not necessarily need to enter KEYWORDS to do a RELMA  search. Instead, you can select one or more nodes in the hierarchies (Trees)  that are accessible via the "Hierarchy & Search Limits" button. Just "check" one or more of the check boxes and then click the SEARCH button. This method isn't as fast as a keyword search and it isn't recommended that you select large sets (e.g. doing this type of search with just  Microbiology checked would be a bad idea) but it is a technique that is useful in many situations.
