Abstract: Objective To study the application of the risk aversion model in emergency department staff,and to observe the situation of nursing staff's injury rate and nursing satisfaction after the application of the model. Methods Sixty-two cases in our hospital emergency department nursing staff were selected from December,2013 to December,2015 as the research object.There were 4 males and 58 females,which aged between 23 and 47 years old and whose average age is (30.1±12.6) years old,with one to 25 service years and (10.3±8.7) average working years.With the application of risk aversion model to the high-risk groups,we investigate 62 cases of emergency department nurses suffered damage details (including extent of injury and frequency of clinic visits),occurrence rate and patient satisfaction with nursing personnel service. Results Comparison of high-risk groups one month before and after the application of risk aversion model shows that before the application of injuries in a damage,secondary injury and hurtful words were higher than those after the application (P<0.05),suggesting that high-risk aversion model for emergency department injury event number of dodge.Relatively high-risk groups to avoid mode before and after the application of emergency department visits and injury occurrence,and calculate the damage rate,use of high risk population aversion mode after damage rate dropped to 9.9%,below the high-risk groups to avoid application mode before damage rate of 26.7%(P<0.05),suggesting that high-risk population evading model for emergency department can help avoid injury event numbers.Before and after the application of the model,the satisfaction rate of emergency patients to nursing staff was 72.6%,far higher than the rate before the application of risk aversion model 54.8%(P<0.05). Conclusion The application of risk aversion model in emergency nursing staff can effectively reduce the incidence of injury,and effectively increase the satisfaction of patients to nursing service,which is worthy of clinical application.
