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:
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. |
The following is a list of data elements provided for PNDS:
