ICNP (ICNP) - Metathesaurus Representation


This page lists UMLS Metathesaurus data elements and traces them back to the specific source data that populates them.

Skip to: Atoms, Attributes, Definitions, Relationships, Mappings

VSAB: ICNP_2017

Summary of Changes

There are no changes to the primary ICNP terminological data file format or to UMLS source processing.

Source Provided Files:

The file "ICNP 2017 Release.xlsx" includes the following tabs:

DC Asserted
IC Asserted
DC Inferred
IC Inferred

The mappings to SNOMEDCT are provided in a separate spreadsheet:  "ICNP-SCT Mapping 2017.xlsx"

Identifiers:

Identifiers are assigned as follows:
  • CODE: concept code
  • SAUI: N/A
  • SCUI: concept code
  • SDUI: N/A

Atoms (MRCONSO):

Term Type Origin
MTH_PT American English form of British PT. This data is added during Metathesaurus construction.
PT Extracted from the "Preferred Term" value on the asserted tabs of the .xlsx file.
XM Cross mapping atom to represent ICNP-SNOMEDCT map set. This data is added during Metathesaurus construction.

Attributes (MRSAT):

Attribute Name Origin
ICNP_TYPE Inferred from the .xlsx file, based on which tab the concept appears on
FROMRSAB This data is added during Metathesaurus construction.
FROMVSAB This data is added during Metathesaurus construction.
MAPSETRSAB This data is added during Metathesaurus construction.
MAPSETVERSION This data is added during Metathesaurus construction.
MAPSETVSAB This data is added during Metathesaurus construction.
MTH_MAPFROMCOMPLEXITY This data is added during Metathesaurus construction.
MTH_MAPFROMEXHAUSTIVE This data is added during Metathesaurus construction.
MTH_MAPSETCOMPLEXITY This data is added during Metathesaurus construction.
MTH_MAPTOCOMPLEXITY This data is added during Metathesaurus construction.
MTH_MAPTOEXHAUSTIVE This data is added during Metathesaurus construction.
TORSAB This data is added during Metathesaurus construction.
TOVSAB This data is added during Metathesaurus construction.

Definitions (MRDEF):

No definitions are present for ICNP.


Relationships (MRREL):

REL RELA
Inverse RELA
ORIGIN
PAR
CHD
SIB
<no RELA> Represent the hierarchy. Extracted from "Parent Code" and "Child Code" data on the "inferred" tabs of the .xlsx file
SY mapped_to
mapped_from
Represent one-to-one relationships with SNOMED CT. Mappings where the "Notes" cell is empty are represented as "SY".
SY mth_british_form_of
mth_has_british_form
Connect MTH_PT to PT.
This data is added during Metathesaurus construction

Mappings (MRMAP, MRSMAP):

SNOMED CT mappings are extracted from "ICNP-SCT Mapping 2017.xlsx." Mappings are also represented in MRREL.RRF, with REL = "SY," RELA = "mapped_to"
