PNDS (Perioperative Nursing Data Set) - Metathesaurus Representation


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

VSAB: PNDS_4_2018


Summary of Changes

There have changes made to the layout of the Perioperative Nursing Data Set (PNDS) .xslx file that do not directly affect content.


Source Provided Files:

The PNDS distribution includes the following:

Data Files

File Name Description
PNDS 2021.xlsx An Excel file with 6 tabs: Domain, Assessment, Nursing Problems, Outcomes, Implementation, and Evaluation

Identifiers:

Identifiers are assigned as follows:

CODE Value of CODE column
Additional hierarchical navigational atoms: MTHU# assigned during Metathesaurus source processing
SAUI Not Applicable
SCUI Same as CODE
SDUI Not applicable

Atoms (MRCONSO):

Term Type Origin
HT HT atoms are created for each "Domain." In addtion, for navigational purposes, HT atoms are created for each tab: Assessment, Problem, Implementation, Outcome, Evaluation
PT
PT atoms are created for assessments, evaluations, outcomes, implementations and problems.
XM Cross Mapping Set
This data is added during Metathesaurus source processing.

Attributes (MRSAT):

Attribute Name Origin
SOS For domain atoms: Extension column
For outcome atoms: Interpretive Statement column
For the map set, an SOS is added during UMLS Metathesaurus source processing
FROMRSAB N/A This data is added during Metathesaurus source processing
FROMVSAB N/A This data is added during Metathesaurus source processing
MAPSETRSAB N/A This data is added during Metathesaurus source processing
MAPSETTYPE N/A This data is added during Metathesaurus source processing
MAPSETVERSION N/A This data is added during Metathesaurus source processing
MAPSETVSAB N/A This data is added during Metathesaurus source processing
MTH_MAPFROMCOMPLEXITY N/A This data is added during Metathesaurus source processing
MTH_MAPFROMEXHAUSTIVE N/A This data is added during Metathesaurus source processing
MTH_MAPSETCOMPLEXITY N/A This data is added during Metathesaurus source processing
MTH_MAPTOCOMPLEXITY N/A This data is added during Metathesaurus source processing
MTH_MAPTOEXHAUSTIVE N/A This data is added during Metathesaurus source processing
TORSAB N/A This data is added during Metathesaurus source processing
TOVSAB N/A This data is added during Metathesaurus source processing

Definitions (MRDEF):

For Domains, definitions are created from data in the "Domain definition" column. For all other tabs, definitions are created from data in the "CODE_DEFINITION" column.


Relationships (MRREL):

REL RELA
Inverse RELA
ORIGIN
PAR
CHD
N/A Hierarchical relationships created from the following data:
  • Parent-child relationships based on code: In the "CODE" column, the child code is represented with the same code as the parent with a decimal and incremental numbers for each child. For example, the children of Im.280 are Im.280.1 and Im.280.2.
  • Domains: Domains are added to the hierarchy based on the "Domain Range" column
  • Additional HTs were created for Assessment, Evaluation, Implementation, and Outcome. These atoms are used to create the top of the multi-level representation. Each domain encompasses a range of codes. For example, for interventions relating to "Assessment," codes A.0 - A.199 fall under Domain 1, "Safety." PNDS contexts were built to reflect this organization.
RQ mapped_to/mapped_from Created using the "SCT" data.

Mappings (MRMAP):

Mappings to SNOMEDCT_US are created using the "SCT" data.
