Summary of Changes

The NANDA-I data format had signficant changes, and UMLS source processing was adjusted accordingly.

New ATNS:
  • LOE
  • SOS
New RELA/RELA_INVERSE:
  • associated_condition_of/has_associated_condition
  • population_at_risk_for/has_at_risk_population

Identifiers:

Identifiers are assigned as follows:

CODE:
  • TTY = HC: Domain Id concatenated with Class Id (e.g. 3_10)
  • TTY = HT: Domain Id
  • TTY = PT: Diagnosis Code
  • TTY = RT: Phrase Code
SAUI: Not applicable
SCUI: Not applicable
SDUI: Not applicable

Atoms (MRCONSO):

Term Type Origin
HC Domain Id concatenated with Class Id
STR: Class Label
Suppress = "N"
HT CODE: Domain Id
STR: Class Label
Suppress = "N"
PT CODE: Diagnosis Code
STR: Diagnosis Label
Suppress = "N"
RT CODE: Phrase Code
STR: Phrase
Suppress = "N"


Attributes (MRSAT):

ATN Origin Notes
DATE_CREATED Year Established <YYYY> format
DATE_LAST_MODIFIED Revision Year May have multiple <YYYY> values
LOE LOE Level of Effort; for clarity, the ATV includes the numeric value of the LOE as well as an expanded explanation
SOS Footnote
SUBCATEGORY Subcategory Indicates a subheading designated by the DC/ReF/RiF field. Attached to the RUI for the relationship between the PT and RT atoms.

Definitions (MRDEF):

Extracted from "Domain Definition," "Class Definition," and "Diagnosis Definition" fields.

Relationships (MRREL); Hierarchy (MRHIER)


REL RELA
Inverse RELA
Origin
RO associated_condition_of

CHD
PAR
(no RELA) Hierarchy, created based on the Domain, Class and Diagnosis
SIB (no RELA) Relationships between codes with the same parents.

Mappings (MRMAP):
