Objective To explore the effect of applying Kiken-Yochi Training（KYT）model in risk management for nursing adverse events. Methods In the prospective quasi-experimental study, 13 346 patients admitted from January to June 2022 were included into the pre-intervention group and another 11 520 patients admitted from July to December 2022 were included in the post-intervention group.The pre-intervention group was subjected to nursing adverse event management using conventional method, while the post-intervention group was subjected to nursing adverse event management based on the Kiken-Yochi training model. The safety beha-vior scores of nurses before and after the intervention were compared, and the incidence rates of patient adverse events and complaints and disputes in the pre-intervention group and the post-intervention group were compared. Results After intervention, the safety behavior score of nurses significantly increased from before (P＜0.05).The incidence rates of such adverse events as medication errors, falls, unplanned extubation, and the incidence rate of complaints and disputes in the post-intervention group was significantly lower than those in the pre-intervention group (all P＜0.05). Conclusion KYT model can effectively improve nurses′ safety behavior and reduce the incidence of adverse events, as well as incidence of complaints and disputes.
