Objective To study the current situation of emergency nurses' structural empowerment,competency,job satisfaction,and their correlative factors.Methods Literature review, interview and questionnaire were used to establish the emergency nurses' structural empowerment and competency model.300emergency nurses were structurally empowered,and their quality of care and job satisfaction was compared before and after.Results The quality of care and job satisfaction after structural empowerment was (98.45 ±1.36) and (98.19 ± 2.63 ),both of which were higher than that before structural empowerment (95.33 ±2.47) and (93.81 ± 4.54),and the differences were statistically significant (t =-4.468,16.136,respectively; P ＜ 0.05).After structural empowerment,there was great improvement in emergency nurses' selfevaluation,as well as their ability of critical thinking,receiving information,communication and health education,while there was little improvement in their ability of social support,logical reasoning and innovation.Conclusions Establishing structural empowerment and competency model for emergency nurses helps them position themselves and promote their development,as well as provides reference to select and train professional nurses for hospitals.
