In this regard, this study aimed to determine the epidemiological causes of road accident mortality in the intensive care unit of Besat Educational-medical Hospital in Hamadan during Nowruz Holidays 2018. Material and Methods: In this descriptive cross-sectional study, data of the patients died for 13 days in Nowruz Holidays in the intensive care unit of Besat Hospital in Hamadan, by census method, was extracted from the  medical records of patients by using a checklist from a researcher-made questionnaire. Data were analyzed by Fisher's exact test and SPSS 21 software. Results: Of the 28 Patient admitted to the intensive care unit,16 patients died. Most deaths were in the third decade of life, among single men, with a self-employment job, with diploma education level or cycle education level, with more than 10 days of hospitalization and in the night shift. Based on the results, most of the dead persons were rider (81.25%), suffered head trauma (50%), with head surgery (56.25%), without any underlying illness (93.75%) and without successful experience of cardiopulmonary resuscitation (87.5%). There were no statistically significant differences between the variables and mortality rate (P value > 0/05). Conclusion: Young single men with low level of education are a wide range of road accidents victims. Therefore, it seems it's necessary to reduce mortality from these accidents, health planning such as traffic culture training and driving rules, by using social media, should focus on learning and improving the level of community awareness, especially in this group of people   https://jbe.tums.ac.ir/index.php/jbe/article/view/378
