Triage in the system of integrated emergency hospital admissions of the Republic of Croatia is the place where patients first report when they have certain health issues. The triage process is conducted by an educated nurse or technician, who, based on the patient’s health condition, their clinical knowledge, and completed triage education, determines the triage category to which the patient belongs. The main and primary goal of triage is to quickly identify conditions and illnesses that may harm the patient and to start their treatment as soon as possible. Given the large number of patients in emergency services, it is necessary to systematically and categorically determine which patient belongs to which category, while also considering the available resources, as well as staffing and financial capacities. The aim of this research was to examine the knowledge of students about the triage system in the field of emergency medicine in the Republic of Croatia, the students' interest in further education about the triage system, and whether graduate students have more knowledge than undergraduate students. The research was conducted through a survey questionnaire in July and August 2024, and the respondents were students of undergraduate and graduate nursing programs. The survey was conducted via the Google Forms platform and distributed by the examiner through an online link. Analysis of the results showed that nursing students possess commendable knowledge of the triage system used in the Republic of Croatia, and they show an interest in increasing their knowledge. However, no statistically significant difference was found between graduate and undergraduate students in the amount of knowledge about triage.
