Researchers in South Korea translated the Perioperative Nursing Data Set (PNDS) into Korean and tested its validity and usefulness in South Korean clinical settings. To evaluate the usefulness of the translated PNDS, 142 nurses were surveyed, and the narrative nursing notes of 20 surgical patients discharged from two tertiary hospitals in Seoul, South Korea, were analyzed and mapped using the PNDS. Although nurses found it to be useful, the researchers recommend certain additions to the PNDS, including the addition of action-related statements, to improve its usefulness in Korean perioperative settings.
