The Emergency services ward at the General Hospital Karlovac was implemented towards the end of 2012, as part of the Reform Project of urgent medicinal aid in Croatia. The aims of this project were to give medicinal aid to urgent patients in one place and thus minimising the number of unnecessary hospital admissions and cost of treatment. The ward is the central place for admission, processing, and any further definitive treatment of urgent patients regardless of the referred diagnosis. By admission to the Ward every patient goes through the formal process of triage by which the urgency category is determined, depending on ailments or injuries. The modified Australasian triage scale is used, it has 5 urgency categories, and determines the maximum safe waiting time for doctors examination, and varies between 0-240 minutes. Differential-diagnostic and therapeutic procedures are implemented in the Ward, as well as specialist examinations. Following the processing and the set diagnosis the patient is either hospitalised or discharged for home care. This paper discusses the specific meaning of the Department of the emergency room to work in Karlovac General Hospital.
