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:
The PNDS distribution includes the following:
|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.|
The following is a list of data elements provided for PNDS:
TTY = "HT"
||This field may have one of the following values:
An obsolete (retired) code from PNDS, 2nd edition
"NA" (indicates that a code is new and the obsolete code value is not applicable
"Definition" (indicates that the row contains a new or revised definition
"Interpretive Statement" (indicates that the row contains a new or revised interpretive statement)
||The atom name, definition, or interpretive statement from the 2nd edition of PNDS, if applicable
||Not included in Metathesaurus processing
||The PNDS2011 code, if this row represents a concept; otherwise null
||The atom name, definition, or interpretive statement from PNDS2011
The representation of this field is dependent on the value of the "Obsolete code":
||The domain associated with this PNDS code, if this row represents a concept; otherwise null
||Used to create the hierarchy
||Information regarding revisions, additions, or deletions of atom names or attributes, if applicable; otherwise null
||Not included in Metathesaurus source processing
