2009AB UMLS® Release Notes and Bugs
Printer-friendly VersionWhat's New
Metathesaurus®
One new source was added:
- Routine Health Outcomes (LNC_RHO)
29 English sources and 9 translation sources were updated. These include ICNP®, MeSH®, MedDRA, RxNorm, and SNOMED CT® (English and Spanish). For a complete list of updated sources, see the Updated Sources Web page. For more detailed information on changes in this version of the Metathesaurus, see the Updated Sources (Expanded) Web page.
The CORE (Clinical Observations Recording and Encoding) Problem List Subset of SNOMED CT® is a new content view (a pre-defined Metathesaurus subset). Content views are explained in the “Need to Customize the Metathesaurus” section of the Metathesaurus documentation.
ICD10PCS_2009 to ICD9CM_2009 reimbursement mapping has been added. The mapping is available in MRMAP.RRF (and MRSMAP.RRF) under MAPSET CUI C2696948.
MDRJPN will no longer be updated in future releases.
Data Changes
RxNorm
- Precise Ingredient Name: TTY= “PIN” has been added. Some records that previously had TTY=“IN” now have TTY=“PIN”. The atoms where SAB=“RXNORM” and TTY=“IN” and that belonged to concepts with the RELAs “precise_ingredient_of” and “form_of” have had their TTY changed from “IN” to “PIN”.
- Synonyms: TTY=“SY” (synonym) atoms can be created for normal forms of the type GPCK, BPCK, SCD, or SBD. Each of these normal forms may now have multiple SY atoms in their concepts.
- “SY” relationships are no longer created for terms where TTY=“OCD” within a concept in RXNREL. Therefore, these rows (approximately 130,000 rows) are no longer present in MRREL.
General
- A full Metathesaurus subset now requires 20.2 GB of disk space.
- Windows users must click on the run.bat file (formerly windows_mmsys.bat) to launch MetamorphoSys from the UMLS DVD or from the files downloaded from the UMLS Web site. All other operating system launch scripts have the prefix “run” followed by an underscore and the operating system name (e.g., run_linux.sh).
- The 2009AB MetamorphoSys Release is not backward compatible. Configuration files from previous MetamorphoSys versions cannot be opened with the 2009AB MetamorphoSys Release. Configuration files created with this release will be compatible with future releases.
- Macintosh users will need the Java Runtime Environment (JRE) Version 1.6 to create or browse a subset. A separate MetamorphoSys Release download will be available from the UMLS Web site for JRE 1.5 users. This download will include 2009AB data with the 2009AA version of MetamorphoSys. The separate MetamorphoSys download will not be created for future releases.
New Filters
- Unique Identifiers – Include/exclude specific Concepts, Descriptors, Codes, and other identifiers.
- Source Subsets – Extract a pre-defined subset based on a specific source (currently only SNOMED CT and SNOMED CT Spanish subsets are available).
- Unicode – Tell MetamorphoSys how to handle non-ASCII Unicode characters in a subset.
- The Unicode filter was formerly the “Remove Unicode” option on the “Output Options” tab.
- Sample Meta – Creates a small, diverse subset that satisfies a variety of data conditions.
New Features for Developers
- Write customized MetamorphoSys plug-ins using Java Plug-in Framework architecture.
- Browse the Metathesaurus using an Oracle or MySQL database.
- Create a subset directly from an Oracle or MySQL database.
- Create output subsets in UTF-8, UTF16-LE, or UTF16-BE.
New Load Script Options
- Output load scripts without creating an entire subset.
- Create MS Access 2003 load scripts for RRF files (for subsets < 2GB).
- Create Semantic Network load scripts.
RRF Browser – New Browsing Options
- Cluster views – View data at the level of individual sources by Concept, Code, Source Concept, or Source Descriptor.
- Hyperlinked data in Report View – Switch easily between cluster views.
- Refine searches – by source vocabulary, content view, or semantic type.
- Highlight search results – by content view or source(s) of interest.
Details and screenshots are available on the RRF Browser Web page.
UMLS Learning Resources:
The UMLS Web site has been reorganized into four categories: New Users, User Education, Knowledge Sources, and Implementation Resources.
As part of the UMLS Web site reorganization, the UMLS Release Documentation was rewritten as the UMLS Reference Manual. Information specific to a UMLS Release, such as sources included in the current version of the Metathesaurus and statistics regarding the number of concepts, remains on the UMLS Web site while general information now resides in the Reference Manual.
2009AB Source Release Documentation pages will be published following the release.
Users who are new to the UMLS are encouraged to review the New Users' homepage. This page includes online demonstrations, step-by-step guides and a link to UMLS training materials.
Bugs
Title: OMIM Data Errors
Problems:
- Two HT terms were misspelled in the file received from the source. The terms GENITOURINIARY and NEPLASIA were placed under the RHT, adding two false axes to the hierarchy. Both of these terms are also present in their correctly spelled forms, GENITOURINARY and NEOPLASIA.
- The OMIM term “Behavioral/psychiatric manifestations” (UMLS CUI C1854373) has two erroneous variant terms, “Psychiatric/behavioral manifestations” and “Behavioral/psychiatric Manifestations”.
Solution: The corrected terms will be present in the next version of OMIM in the Metathesaurus.
