N2 - Background Evidence regarding the mental health needs of trafficked people is limited; however, prevalence of depression and post-traumatic stress disorder is high among trafficked people who are in contact with shelter services. We aimed to investigate the sociodemographic and clinical characteristics of trafficked people with severe mental illness. Methods We did a historical cohort study of trafficked people in contact with secondary mental health services in South London, UK, between Jan 1, 2006, and July 31, 2012. We searched and retrieved comprehensive clinical electronic health records for over 200 000 patients from the Case Register Interactive Search database to identify trafficked patients. A matched cohort of non-trafficked adults was generated by simple computer-generated random selection of potential controls for each case within the parameters of matching criteria. We extracted data on sociodemographic and clinical characteristics and abuse history, and used multiple imputation to deal with missing data. We fitted logistic regression models to compare trafficked and non-trafficked patients. Findings We identified 133 trafficked patients, including 37 children. 78 (81%) of 96 adults and 25 (68%) of 37 children were female. 19 (51%) of 37 children were trafficked for sexual exploitation. Among both adults and children, the most commonly recorded diagnoses were post-traumatic stress disorder, severe stress, or adjustment disorder (27 adults [28%] and ten children [27%]) and affective disorders (33 adults [34%] and ten children [27%]). Records documented childhood physical or sexual abuse among trafficked adults (41 [43%]) and children (28 [76%]), and adulthood abuse among trafficked adults (58 [60%]). Trafficked adults were more likely to be compulsorily admitted as a psychiatric inpatient than non-trafficked adults (adjusted odds ratio 7·61, 95% CI 2·18–26·60; p=0·002) and had longer admissions (1·48, 1·01–2·15; p=0·045). No association was found between trafficking status and either adverse pathway into care (adjusted odds ratio 0·91, 95% CI 0·40–2·05; p=0·82) or substance misuse problems (0·55, 0·27–1·17; p=0·12). Interpretation Severe mental illness in trafficked people is associated with longer admissions and high levels of abuse before and after trafficking. Evidence is needed on the effectiveness of interventions to promote recovery for this vulnerable group. Funding Department of Health Policy Research Programme
