Inter-rater and intra-rater reliability of performed triage by participations was measured. Thirteen nurses were randomly selected. Thereafter, at the end of each working shift, patient data recorded in the daily data registry forms were collected. Then, duration of hospital stay, number of cases admitted to general wards or intensive care units, number of cases discharged from the ED within 12 hours and mortality rate were compared with the triage level determined by the nurse. Results: In total, 30 nurses with a mean age of 28.4 ± 3.7 years were enrolled. In this study, 1491 triage cases (61.6% male) were evaluated, of which 4.2% were triaged as level 1, 18.3% as level 2, 37.1% as level 3, 20.4% as level 4 and 20.0% as level 5. The following outcome was observed: 3.64% were discharged, 6.29% were hospitalized, 3% died and 2.3% were discharged against medical advice without completing treatment. The correlation of determined triage level and patients’ duration of hospitalization was significant based on one-way ANOVA test (p = 0.000). The outcome of the patients significantly correlated with the level of triage determined by the study nurses (p = 0.000). Conclusion: Based on the findings, it appears that triage performed by the study nurses educated by those who participated in TOT workshop through cascade training system had perfect validity. https://fem.tums.ac.ir/index.php/fem/article/view/127 https://fem.tums.ac.ir/index.php/fem/article/download/127/188
