The Perioperative Nursing Data Set (PNDS) is a standardized nursing vocabulary that addresses the perioperative patient experience from pre-admission until discharge. As a nursing language, it is parsimonious, validated, reliable, and useful for clinical practice. This issue of Perioperative Nursing Clinics includes articles on such topics as applying the PNDS across age and population-specific groups; using the PNDS in performance improvement; realistic use of the PNDS in academic nursing; and a perioperative visit to Brazil.
