Field # | Field Name | Description | Representation |
---|---|---|---|
1 | MEDCINID | MEDCIN concept ID | MRCONSO.CODE MRCONSO.SCUI MRCONSO.TTY = FN |
2 | CONCEPT_DESCRIPTION | Fully-specified concept name with domain appended in parentheses | MRCONSO.STR |
Field # | Field Name | Description | Representation |
---|---|---|---|
1 | MEDCINID | MEDCIN concept ID | MRCONSO.CODE MRCONSO.SCUI |
2 | DESCRIPTION | Concept description | MRCONSO.STR |
3 | PREF_FLAG_ID | 1 = preferred, 0 = non-preferred | 0 => MRCONSO.TTY = "SY", 1 => MRCONSO.TTY = "PT" MRSAT.ATN = "PREF_FLAG_ID" (STYPE = "AUI") |
Field # | Field Name | Description | Representation |
---|---|---|---|
1 | MEDCINID | MEDCIN concept ID | MRHIER.CUI populated by the Metathesaurus CUI corresponding to MEDCINID. |
2 | NODEKEY | Hierarchical identifier | Used to construct the hierarchical tree position, MRHIER.PTR,
for this concept. The "NODEKEY" value is a series of two-character
tokens (some of which include a space character), e.g., " CDA D P"
breaks down as "<space>C", "DA", "<space>D", and "<space>P", and removing the last token
(yielding " CDA D", in this example) produces the "NODEKEY" value of
this concept's hierarchical parent. Also used to populate MRHIER.HCD. Note that leading space characters have not been removed from the HCD value. |
Field # | Field Name | Description | Representation |
---|---|---|---|
1 | MEDCINID | MEDCIN concept ID | MRREL.CUI2 populated by the Metathesaurus CUI corresponding to MEDCINID |
2 | RELATIONSHIPTYPE | The SNOMEDCT CONCEPTID indicating the type of this relationship | Mapped to corresponding values in MRREL.REL and MRREL.RELA.
E.g., the "RELATIONSHIPTYPE" 123005000, which is the SNOMEDCT CONCEPTID
for "Part of (attribute)", is mapped to REL = "RN" (narrower
relationship) and RELA = "part_of". If RELATIONSHIPTYPE = "168666000" (same_as), MRMAP.RRF and MRSMAP.RRF entries are also created. |
3 | SCT_CONCEPTID | The SNOMEDCT CONCEPTID of the concept having the specified type of relationship to the concept indicated by MEDCINID | MRREL.CUI1 populated by the Metathesaurus CUI corresponding to SCT_CONCEPTID |
4 | PREF_FLAG_ID | 1=preferred, 0=non-preferred | MRSAT.ATN = "PREF_FLAG_ID" (STYPE = "RUI") |
