Abstract: Objective To investigate the status quo of workplace interruption among nurses in three tertiary hospitals in Sichuan Province,and analyze its influencing factors,in order to provide reference for improving the current situation of workplace interruption for nurses and optimizing management plan. Methods From March to April 2024,873 nurses from three tertiary hospitals in western China were selected by convenience sampling method. The socio-demographic data questionnaire,the workplace interruption scale,and the nurses' professional deviation behavior scale were used to conduct the survey,and the data were analyzed. Results The total workplace interruption score of 873 nurses was （22.12±5.18）points,and the dimensional score from high to low was intrusion[（6.21±1.89）points],distraction[（5.59±1.98）points],rest[（5.38±1.75）points],and found to be discrepant [（4.94±1.41）points]. Pearson correlation analysis showed that nurses' workplace interruption was positively correlated with professional deviation behaviors（r=0.409,P<0.01）,which could explain 31.6% of the variation in nurse workplace interruption scores. Conclusion The workplace interruption behavior of nurses in three tertiary hospitals in Sichuan Province is at a moderate to low level. Nurses who are older,have worked for longer periods of time,have higher work intensity,have not received workplace interruption training,and have experienced workplace violence within the past year and have higher professional deviant behaviors have a higher level of workplace interruption. It is suggested that nursing managers should pay attention to the mental health of such nurses and actively take effective measures to further reduce workplace interruption.
