Abstract: Objective To explore the application effect of 531 night ward round system in the general duty of head nurses, and to provide reference for further improving the quality management of night nursing in hospitals. Methods Using the book “Clinical Nursing Practice Guidelines” developed by our hospital as the standard of room inspection, the 531 room inspection record sheet of the chief nurse on general duty was designed and incorporated into the content of the chief nurse on general duty supervision. Before and after 12 months of implementation, the hospital-wide nighttime nursing adverse events were retrieved and the nurse leaders were asked to fill out a patient safety competency self-assessment scale to evaluate the effectiveness of the developed 531 night check-in system in the chief nurse's general duty. Results After the implementation of the 531 night ward round system in the head nurse' s general duty, the number of adverse events in the night departments in 2022 was lower than that in 2021, and the number of grade Ⅲ events in 2022 ( without consequences ) was significantly lower than that in 2021 (P<0.05). After the implementation, the total score of the head nurse patient safety competency self-rating scale was higher than that before the implementation, and the difference was statistically significant (P<0.05). Conclusion By implementing the 531 night check-in system in the chief nursing officer's general duty, it standardized the various tasks of night nursing in our hospital departments and improved the quality of night nursing supervision, while the standardized check-in process system also helped improve the chief nursing officer' s patient safety competency.
