The rate of patients’ admission to the emergency department is not planned exactly. Due to the bad condition of the patients, the triage management is also very momentous. Therefore, up-to-date training has a particular importance for nurses.

37 emergency nurses were selected by census method through quasi-experimental study. Data collection tools were four questionnaires of demographic characteristics, triage attitude assessment, triage accuracy and triage knowledge which determined the total staff performance. They were completed by them once before the training, one month after training and three ninety-minute training sessions. Data were analyzed by Wilcoxon, Man Whitney U, t-test and SPSS version 20.

59.5% of them were females, 51.4% were married, 94.6% did not have a bachelorchr(chr('39')39chr('39'))s degree, 64.9% had not rotating shifts and 62.2% had not the experience of participating in training programs about accidents and disasters. The mean score of nurses’ knowledge increased from97± 3.59before the intervention to 17.46 ± 3.22 after the intervention, also, the mean score of nurses’ accuracy ranged from 15.16 ± 5.86 to 20.89 ± 4.25; finally, the mean of attitude score ranged from 125.8 ± 15.9 to135.4± 14 (P <0.0001). The most impact of interactive learning was related to triage attitude with the mean score of  9.62. There was also a significant association of the knowledge improvement indicator with the last degree (P = 0.04) and the association of the knowledge improvement indicator with gender (P = 0.05).

Emergency nurses had better knowledge, accuracy and attitude than before interactive training programs. Significant increase in knowledge and attitude scores could indicate an increase in nurseschr(chr('39')39chr('39')) readiness and vigilance to perform better triage at emergency departments. The impact of interactive training on nurses’ attitudes on disasters triage can enhance emotional performance and create deeper cognitive learning which has everlasting effects on nurses’ performance; the emergency staff can have better performance through triage of accidents and disasters.
