“…Triage is defined as a rapid process of categorizing patients upon arrival to determine priorities for further evaluation and treatment (Gräff, Goldschmidt, Glien, Bogdanow, Fimmers, & Hoeft, et al, 2014;Saeed, Al-Fayyadh, Alshomar, Zekry, & Alamiri, et al, 2017). Most of the triage systems applied in the ED are based on a five-level triage where this triage system has been conferred to improve the patient care outcomes historically (Andrade-Silva, Takemura, Bellato, Leonhardt, & Kojima, et al, 2019;Ekins & Morphet, 2015). There are variations in the application of triage systems that are tailored to the availability of resources, the economic situation, and the capacity of patients in each EDs in the wide world (Saeed, Al-Fayyadh, Alshomar, Zekry, & Alamiri, et al, 2017).…”
