VSAB: PNDS2011

Summary of Changes

There have been significant changes made to the structure of the Perioperative Nursing Data Set (PNDS) and the way codes are assigned since the previous version was processed for inclusion in the Metathesaurus.  PNDS 2nd edition (PNDS2002) included outcomes, diagnoses, interventions, and domains, which were assigned term types of PS/PX, DX, IV, and HT, respectively.  In the current verison, there are assessments, evaluations, implementations, outcomes and domains, and term type assignments have changed accordingly.  Domains are still assigned TTY = "HT," as are placeholder atoms for "Assessment," "Evaluation," "Implementation," and 'Outcome," which were created for the purpose of representing a navigational hierarchy.  All other PNDS atoms are assigned TTY = "PT." 

The domains are the same and have the same codes as the previous version, but the code assignment for everything else has changed, and the strings have often changed also.

Differences between PNDS2002 and PNDS2011 in RRF format are:

1)  The SRL has been changed from 0 to 3 for PNDS.

2)  New term type (TTY) | Suppressible value:
      PT|N

3) Dropped term type (TTY):
      DX
      IV
      PS
      PX

3) Dropped relationship | relationship attribute(RELA):
      RQ|has_outcome

This data is not available in machine-processable form

4) New attribute name (ATN):
      INTERPRETIVE_STATEMENT
      RETIRED_CODE
      SOS

5) Dropped attribute name (ATN):
      INTERVENTION_DESCRIPTION
      INTERVENTION_SEQUENCE
      INTERVENTION_TEXT
      OUTCOME_EXAMPLES
      OUTCOME_INDICATORS
      OUTCOME_STATEMENT

The PNDS distribution includes the following:

Documentation and Reference

The electronic distribution of PNDS did not include documentation or reference material.  However, the printed book, "Perioperative Nusing Data Set 3rd Edition" may provide additional insight into the content and usage of PNDS and information is available here:  http://www.aorn.org/PracticeResources/PNDSAndStandardizedPerioperativeRecord/

Data Files

File Name Description
Revised PNDS codes all_Def_Final_10_29_10  (5).xlsx
An excel file with 5 tabs:  Assessment, Evaluation, Implementation, Outcome and Domain.  Includes obsolete codes and labels, new codes, new labels, domains, and notes.  Includes definitions and interpretive statements.  This table contains essentially the same content as Chapter 3 in the printed book, however there are minor differences due to editing.

Identifiers:

Identifiers are assigned as follows:

CODE
Domain tab:  Value of column 1 (Code)
All other tabs:  Value of column 3 (New code)
Additional hierarchical "placeholder" atoms:  MTHU# assigned during Metathesaurus source processing
SAUI
Not Applicable
SCUI
Same as CODE
SDUI
Not applicable

Atoms (MRCONSO):

Term Type Origin

PT


Attributes (MRSAT):

Attribute Name Origin
INTERPRETIVE_STATEMENT

RETIRED_CODE


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 "New labels" column, where the "Obsolete code" column has the value "Definition."


Relationships (MRREL):

<none>
Context relationships created from the following data:
  • Parent-child relationships based on code:  In the "New code" column, the child code is represented with the same code as the parent with a period and incremental numbers for each child.  For example, the children of Im.280 are Im.280.1 and Im.280.2.
  • Domains:  The domain provided in the "Domains" column of the Assessment, Evaluation, Implementation, and Outcome tabs are represented as parents.
  • Additional HTs were created for Assessment, Evaluation, Implementation, and Outcome.  These atoms are used to create the top of the multi-level representation.  As indicated on p. 55 of the printed book, within each type of intervention, 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.

Mappings (MRMAP):

No mappings to other sources are provided for PNDS.
