Methods: In this qualitative study, 18 nurses of prehospital emergency ba ses of Shahrekord University of medical sciences were studied. Data was collected by using semi-structured and in-depth interviews, and also it was used content analysis to analyze the qualitative data. The interviews were transcribed verbatim and analyzed concurrently with the data collection.
Findings: By analyzing the data, five main themes were known as the influencing factors in prehospital emergency nurses' decision making which are as follows: 1) patient-related factors; 2) nurse-related factors; 3) environmental factors; 4) colleagues related factors; 5) the factors related with the type of event and mission.
Conclusions: The findings provide a deep understanding of the effective factors in prehospital emergency nurses' decision making.

Introduction: Prehospital Emergency Medical System is one of the critical parts in health care sector which has been usually unnoticed. Delivering quick, efficient, and high quality care in this system has a large impact on mortality and morbidity of patients.
Methods: In this descriptive and cross-sectional study, 20662 cases in 4 months in the middle of the year 2008. Missions over 8 minutes from when the time of call receiving to arrival on the scene were detected and survived, ANOVA software was used for analyzing.
Findings: Most of the missions were done between 8 to10 minutes. Nine reasons were detected for this arrival delay:1) destruction of the road, 2) traffic, 3) rainy weather , 4) long way to the scene, 5)scarcity of ambulance in the center near the scene, 6)wrong address, 7) cannot find the address, 8) delay in dispatching the ambulance, 10)delay in arrival because of technicians. In Shiraz Emergency Medical system the most important reasons for missions over 8 minutes were scarcity of ambulance in the center near the scene, traffic, long way to the scene.
Conclusion: Quick arrival on the scene has a large effect on patients, though, health ministry and emergency centers should pay more attention on this sector and deliver financial support for equipped emergency centers due to the population and demand for emergency centers.

Introduction: Burns prevalence in the world is about one person at every 17 seconds and approximately 6 million people in a year. Therefore, from the pre-hospital emergency care viewpoint, paramedics, ambulance staff, nurses etc. are the first groups that help burned patients before hospital cares. According to the previous studies, there is a lack of pre-hospital care instructions and guidelines for the pre-hospital care services; unfortunately, this can causes anxiety and reduction of appropriate care. This paper aims to evaluate the way of pre-hospital care for burned patients in Iran in comparison with other countries.
Methods: In this systematic review, from the 676 obtained articles, 102 ones were relevant to the subject and finally 91 articles were selected and studied by using international databases and Persian resources.
Findings: The results indicated that there is not the same instruction for pre-hospital care of burned patients not only in different countries but also in Iran. Therefore, it is necessary to establish a standard model for the pre-hospital procedures.
Conclusions: The researchers decided to study this model as a PhD dissertation due to the limited knowledge in field of pre-hospital care of burns and lack of exact definition of burn phenomena.

Introduction: Prehospital care plays an important role in emergency patients’ management. More correct, proper, and faster management of the patients will reduce the mortality and morbidity.
Methods: In this cross-sectional and descriptive-analytical research, all five EMS stations of Shahrekord city were studied in 2016. Data were collected from staff and equipment in Shahrekord EMS stations by using checklists. In addition, about 742 recorded mission reports of central station studies. The status of manpower, equipment status and response time compared with the standards & regulations of Ministry of Health, the standards provided by Institute of Standards & Industrial Research of Iran, reference standards of Iran and North America respectively using excel software and descriptive statistics (percent, cumulative distribution, and standard deviation).
Findings: The results of the study in Shahrekord EMS system are as follows: none of the stations has enough human resources; none of the emergency ambulances was equipped with the necessary equipment; the greatest shortage is related to critical-therapeutic management equipment that only 57.4% of the ambulances used this equipment. The best condition was that about 95.9% of ambulances have respiratory ventilation equipment. Another point was that 81.5% of the requests were answered in less than 6 minutes.
Conclusion: The results indicated that response time is a very important factor in reducing the incidence of illnesses and emergencies, but shortcomings in manpower and ambulance equipment can reduce the effectiveness of missions. Therefore, eliminating the shortage of manpower and equipment seems necessary.
