as safe care. Furthermore, nurse-physician collaboration has the effect of raising the job satisfaction of nurses and reducing nurses' turnover rate [12,13].Nurses can offer high-quality medical care to the patient w h e n the collaborative relationships of nurses and physicians are good. The perception of collaborative relationships of nurse and physician depends on the characteristic of the unit. Nurses practising in surgical units and in emergency departments had positive perceptions of nurse-physician collaboration [14,15].In this way, while nurse-physician collaboration has been shown to have a large impact on acute medical care, in emergency care in Japan, little research has been performed. Therefore, this research aims to clarify the issue of nurse-physician collaboration in emergency medical care; nurses working in emergency medical centres will be able to clarify when they perceive that a cooperative relationship with the physicians is established.The Japanese emergency care system is characterised by three levels of care. Primary emergency care treats slightly injured patients, who do not need hospitalisation. Secondary emergency care treats

Objective: The study purpose was to investigate influencing factors related to nurses' intention to continue employment in tertiary emergency medical facilities. Methods: A self-report questionnaire survey was conducted, and responses were collected by mail. We investigated seven factors associated with the intention to remain employed that were determined by preliminary research. Data were analyzed using a covariance structure analysis. Results: Of the 561 responses received, 461 were found to be valid for analysis. A model showing relationships among the five factors (organizational commitment, job stress, job satisfaction, nurse-physician collaboration, and intention to remain employed) was created. Organizational commitment and job stress were directly related to intention to continue employment, while, nurse-physician collaboration demonstrated effects on the entire model. Conclusions: The strongest factor observed was organizational commitment. The types of institutions examined in the present study almost exclusively treat seriously ill patients. This may explain why nurse-physician collaboration affected the entire model. In a tertiary emergency facility, a nurse can more easily play a critical role in the healthcare process. In the future, it will be important to consider these factors when creating an organizational climate conducive to continued employment.
