Objective of research. Examine the level of stress intensity experience in traumatological patients, determine the stress intensity experience in traumatological patients considering gender, level of education, work and marital status, and type of accident. Draft of study. Extensive research conducted in May, June and July 2017 at the Traumatology Institute, KBC Osijek. Respondents and Methods. There were 50 participants, out of which 27 (54 %) men and 23 (46 %) women. Impact of Event Scale – Revised was used for research. Results. The average score of IES-R was 35 out of a total of 88, avoidance subscale was 12 out of 32 points, intrusion scale was 15 out of 32 points, and hyperarousal scale was 9 out of 24 points. An acute stress reaction was found in 4 respondents, and clinically significant symptoms were found in 10 respondents, which is not to be dismissed. Statistically significant difference was found in the results by sex (p = 0.03). Median sum for men was 30, and 41 for women. The difference was found by working status (p = 0.007), where it is apparent that retirees have the highest value of the total sum. Also, statistically significant differences were found by marital status (p = 0.03), where it can be seen that the divorced and widowed have significantly higher value of the total sum. Conclusion. Acute stress is present in two thirds of the patients after experiencing a certain trauma. Research has shown that women, the retired, and the divorced and widowed suffer more stress from a traumatic event, and use more strategies to avoid, intrude, and hyperarouse when confronted with stressful events
