Emergency medicine in the Republic of Croatia operates through county emergency departments and in acute care hospitals within the framework of integrated emergency hospital admissions (OHBP). The Emergency Medicine Network determinates the number of T1 teams (physician, nurse and driver) and T2 (two nurses) according to the total population and size of the area covered by the county. Unified emergency hospital admissions receive patients who come alone or are brought in by an outpatient emergency department. The Croatian Institute for Emergency Medicine (HZHM) is the head institution for emergency medicine in the Republic of Croatia. The Institute is responsible for proposing the conditions, organization and manner of performing emergency medicine, and participates in performing professional and scientific activities. In front of the nurses working in the emergency medical service there are many challenges that they face every day in all workplaces: field, MPDJ, triage, OHBP, education. Their knowledge and skills are constantly being enhanced and refined through many lectures, educational programs and courses. There are educational programs for nurses in outpatient emergency medical services, for nurses working at MPDJ, triage at OHBP, specialized courses aligned with the European guidelines for resuscitation and airway, Emergency Medicine School and many others.
