Abstract

Background
We aimed to investigate the annual incidence of trauma and stress-related mental disorder including acute stress disorder (ASD) and post-traumatic stress disorder (PTSD) using the National Health Insurance Service Database. In addition, we estimated direct medical cost of ASD and PTSD in Korea.
Methods
To examine the incidence, we selected patients who had at least one medical claim containing a 10th revision of the International Statistical Classification of Diseases and Related Health Problems code for ASD (F43.0) and PTSD (F43.1) and had not been diagnosed in the previous 360 days, from 2010 to 2017. We estimated annual incidence and the number of newly diagnosed patients of ASD and PTSD. Annual prevalence and direct medical cost of ASD and PTSD were also estimated.
Results
The number of newly diagnosed cases of ASD and PTSD from 2011 to 2017 totaled 38,298 and 21,402, respectively. The mean annual incidence of ASD ranged from 8.4 to 13.7 per 100,000 population and that of PTSD ranged from 4.2 to 8.3 per 100,000 population, respectively. The incidence of ASD was found more in females and was highest among the 70–79 years of age group and the self-employed individuals group. The incidence of PTSD was also more common in the female group. However, the incidence of PTSD was highest in the 60–69 years of age group and in the medical aid beneficiaries group. The annual estimated medical cost per person of ASD ranged from 104 to 149 US dollars (USD). In addition, that of PTSD ranged from 310 to 426 USD.
Conclusion
From 2011 to 2017, the annual incidence and direct medical cost of ASD and PTSD in Korea were increased. Proper information on ASD and PTSD will not only allows us to accumulate more knowledge about these disorders themselves but also lead to more appropriate therapeutic interventions by improving the ability to cope with these trauma related psychiatric sequelae.
