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 affect content. In addition, there is an new tab to represent "Nursing Problems." These codes are prefixed with "NP" and are represented with TTY = PT.

PNDS_4_2018 includes mappings to SNOMEDCT_US. These are represented in MRREL.RRF as well as in MRMAP.RRF and MRSMAP.RRF.

New TTY:
  • XM
New REL/RELA:
  • RQ|mapped_to/mapped_from
New ATNs:
  • FROMRSAB
  • FROMVSAB
  • MAPSETRSAB
  • MAPSETTYPE
  • MAPSETVERSION
  • MAPSETVSAB
  • MTH_MAPFROMCOMPLEXITY
  • MTH_MAPFROMEXHAUSTIVE
  • MTH_MAPSETCOMPLEXITY
  • MTH_MAPTOCOMPLEXITY
  • MTH_MAPTOEXHAUSTIVE
  • TORSAB
  • TOVSAB
  • XMAP
  • XMAPFROM
  • XMAPTO

Dropped ATNs:
  • INTERPRETIVE_STATEMENT
  • RETIRED_CODE

Source Provided Files:

The PNDS distribution includes the following:

Data Files

File Name Description
PNDS VERSION 4 FOR NLM.xlsx An Excel file with 6 tabs: Assessment, Nursing Problem, Implementation, Outcome, Evaluation and Domains.

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.txt 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 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" column.

Mappings (MRMAP):

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