The aim of this study is to conduct an epidemiological examination of Turkish citizens and refugees who requested an ambulance due to Out-of-hospital cardiac arrest (OHCA) at the Kayseri 112 emergency services between 2019 and 2020. This study was carried out in the province of Kayseri, which is one of the largest cities in Turkey. The study population includes OHCA patients for whom EMS were activated for any reason in 2019-2020. Data were taken from the Emergency Healthcare Automation System used by Kayseri Emergency Medical Services. A total of 5977 OHCA cases (Turkish 5736, Refugees 241) in which Emergency Medical Servises (EMS) was activated during the research period were included. A rate of 55.6% of patients Turkish nationality and 66.0% refugees were male (p<0.001). Observing at the cause of arrest, we find that 95.7% of cases among Turkish citizens and 82.6% of cases among refugees had a medical cause; while the suicide rate among Turkish citizens was 0.9%, this rate was 5.0% in refugee patients (p<0.001). It was found that the rate of OHCA increased with age and that the average OHCA age was lower in men and refugees. In addition, there is no difference between Turkish nationals and refugees in the use of emergency services for OHCA cases.
