When taking care of a patient in out of hospital scene, we should have in mind the golden hour. Golden hour refers to the period of time following a traumatic injury, during which there is the highest likelihood that prompt medical and surgical treatment will prevent death. The nurse is a very important member of the team in prhospital environment conditions. Its function as a member of the hostage care team is to know all the steps of accessing the injured person, components of the trauma examination, the ways of immobilization, and to provide the patient with psychological support during the transport that such situations usually are stressful. In our study, we determine the total number of traffic accidents in every branch office of the Department of Emergency Medicine of the County of Zadar and the number of patients transferred to the hospital within the golden hour. Furthermore, the aim was to indicate the duration of the intervention from the receiving the call until the end of the transfer. The hypothesis is that the time is crucial in the treatment of the injured. Persons in this study were injured patients in road accidents by the branch offices of the Department of emergency medicine of Zadar County in the period from 1.1.2015. — 31.12.2017., the data is collected from the information system Rinels with the permission of an Ethics Committee of the Department. The largest number of interventions was a red emergency, and most interventions were in the area covered by Zadar. Response interval (time from alarm activation to arrival of first responding vehicle on a scene) was 11-15 minutes, and on-scene interval (time arrival of first EMS responding vehicle on scene until leaving the scene) ranged from 5 to 20 minutes. The hypothesis of the work is confirmed, time is essential for the treatment of the injured. In out of hospital conditions, teamwork is essential, in order for all of the procedures during the treatment to be made at the same time. In that way on scene interval is shortened. What is most important is good communication with the dispatch, within the team and with the patient.
