VSAB: MDRJPN14_1

Summary of Changes:

No changes have been made to the original data files or to representation of MDRJPN in 2012AA.

Source Provided Files:

  The UMLS uses MedDRA files distributed in the ASCII/MDRA_J141 directory:
  • hlgt.asc
  • hlgt_hlt.asc
  • hlgt_j.asc
  • hlt.asc
  • hlt_j.asc
  • hlt_pt.asc
  • intl_ord.asc
  • llt.asc
  • llt_j.asc
  • mdhier.asc
  • meddra_release.asc
  • pt.asc
  • pt_j.asc
  • smq_content.asc
  • smq_list.asc
  • smq_list_j.asc
  • soc.asc
  • soc_hlgt.asc
  • soc_j.asc

Identifiers:

Overview: Lower Level Terms ("LT"s) in MedDRA have any of the following relationships to their "PT":

  • Synonyms: Different terms for the same concept inherent in the "PT" (e.g., "PT" Arthritis and its subordinate "LT" Joint inflammation)
  • Lexical variants: Different word forms for the same expression. These include full names vs. abbreviations and direct vs. inverted word order (e.g., "PT" Acquired immunodeficiency syndrome and its subordinate "LT" AIDS or "PT" Biopsy tongue and its subordinate "LT" Tongue biopsy).
  • Quasi-synonyms: Quasi-synonyms are terms that are not precisely the same meaning as another term, but are treated as synonymous in a given terminology. These include site and laterality descriptions (e.g., "PT" Otitis externa and its subordinate "LT" Bilateral otitis externa).
  • Sub-element: Sub-elements (of the parent "PT") are represented by "LT"s with more detailed information such as anatomic specificity (e.g., "PT"Contusion with LT Bruising of face or "LT" Bruising of leg).
  • Identical "LT": One "LT" is identical to its "PT" for data entry purposes (e.g., "PT" Dementia Alzheimer’s type and its subordinate "LT" Dementia Alzheimer’s type). In this instance, the "LT" and parent "PT" have the same MedDRA code but appear at both levels.

Since MedDRA does not indicate which "LT"s share the same meaning with their "PT", all "LT"s are assigned the same the same Source-asserted Descriptor Identifer (SDUI).  A descriptor is a collection of concepts (or atoms if there is no concept level organization) that are considered to be closely related (but not necessarily synonymous).

Identifiers are assigned as follows:

  • CODE: Populated by the "code" field in original data files, e.g. the code for an "HT" or "HTJKN" atom comes from the hlt_code field in hlt_j.asc
  • SAUI: Not Applicable
  • SCUI: Not Applicable
  • SDUI: Populated by the "code" field in original data files, except for TTY = LT* and TTY = OL*. For these cases, the SDUI is populated by matching the llt code to the MedDRA English llt code and using the SDUI value found in the English version.
