With the development of science and technology and the transformation of nursing models, the requirements for medical care services are increasing. As the majority of locations for applying advanced medical technologies, operating rooms (ORs) are high-risk zones in hospitals, which provide surgery for patients to alleviate even impede the progression of diseases (Lyons & Wing, 2015). During surgery, technical performance of OR staff, including anaesthetist, surgeon, and nurses, could directly affect the safety and health-related outcomes of patients (Fecso et al., 2017;Ugur et al., 2016). In particular, the responsibility of OR nurses for patient safety has been extended, which contains the periods before and after surgery (Niu et al., 2017). Based on these, OR nursing has the characteristics of high load, high risk, heavy responsibility and high pressure. The OR nurses not only have to face intense and heavy work, but also face various occupational hazards, which can easily lead to physical and psychological fatigue (Fang et al., 2010). Increasing studies demonstrated that the OR nurses had more job-related stressors and higher depression and anxiety levels compared to the ward nurses (Cho et al., 2019). As a high-risk occupational group, under the existing conditions, nurses have low overall job satisfaction, strong sense of burnout, high psychological pressure and high turnover rate, which has become a worldwide problem (Carayon &
