Pain after surgery is distressing to patients and is a significant problem in post anesthesia care unit (PACU). Ineffective pain management in the immediate postoperative period can prolong the patient’s length of stay in the PACU which may lead to increased cost of care. The nurses’ lack of knowledge regarding pain management and ineffective team communication are barriers to effective pain management. An educational intervention based on the Knowledge- to-Action Model was implemented to 22 nurses in the recovery room at an urban hospital. A one group pre-test and post-test measure design was used to evaluate educational program. The data was examined in each participant using a paired sample t-test. Educational interventions that target nurses’ knowledge on pain and standardized communication techniques had proven to be effective as management in the PACU (as evidenced by post-test score improvement).
