A Study of Knowledge and Recognition on Postoperative Delirium Among Postanesthesia Care Unit (PACU) Nurses.

Purpose: Postoperative delirium (POD) is a syndrome that often occurs after surgery. Nursing staff are the first-line personnel who have the most time and close contact with postoperative patients. If delirium is not recognized immediately, it will affect the patient's prognosis and increase clinical care requirements and health care costs.
