PReS-FINAL-2041: Macrophage activation syndrome in the children with systemic juvenile idiopathic arthritis during the course of tocilizumab

Background Trauma exposure and posttraumatic stress disorder (PTSD) are common among individuals with a mental disorder, but symptoms often go undetected and untreated. Methods The aim of this study was to determine the prevalence of PTSD among a large sample of adults with psychiatric diagnoses and to establish factors associated with symptoms going undetected. Participants were 1,946 adults recruited by the National Centre for Mental Health. Structured interviews and validated self-report questionnaires were used to ascertain clinical and demographic information for analysis. Results The prevalence of participants screening positive for PTSD that had not been detected by clinical services was 13.9% [12.4–15.5%, 95% confidence interval]). Factors associated with undetected PTSD were female gender, younger age of first contact with psychiatric services, and lower household income. Especially, poor rates of detection were observed after traumatic events, such as child abuse and sexual assault. Conclusions Our findings demonstrate the need for routine assessment of trauma histories and symptoms of PTSD among individuals with anymental disorder
