Efficacy of Telepsychiatry in Refugee Populations: A Systematic Review of the Evidence

Abstract

Introduction Telepsychiatry is becoming an increasingly appealing option for mental health treatment due to its ability to overcome barriers which prevent certain demographics from having access to mental health services. There is a surprising lack of research being done on this promising mode of health care delivery. The aim of this study is to evaluate the existing literature in order to determine the clinical effectiveness and cost-effectiveness of telepsychiatry in resource-constrained environments. Methods Literature searches were performed in PsychINFO, PubMed, Medline, EMBASE, Centre for Reviews and Dissemination, and the Cochrane Library Controlled Trial Registry databases (2000 - May 2017). A search of the following terms was used: telemedicine; telemedical; telepsychiatry; telepsychiatric; teleconsultation; e-health; video conference; and telecare. Type of mental disorder and intervention, along with the clinical outcome or patient satisfaction, were all identified. Exclusion criteria included studies with a sample size of fewer than 10 cases, as well as studies which failed to analyze intervention outcomes. Results Of the 1,477 identified articles, 14 randomized controlled trials were included for review. Despite the methodological limitations and the small number of existing studies, there appears to be limited evidence pointing towards the efficacy of telepsychiatry in resource-constrained environments, although patients and providers tend to prefer face-to-face treatment over video conferencing. Two of the studies included in this paper found video conferencing to be more effective than face-to-face treatment, while none reported the opposite. At the very least, we hypothesize that psychotherapeutic treatment delivered via video conferencing is just as effective as a traditional treatment, albeit less desirable. Conclusion More research is required in order to further evaluate the efficacy of telepsychiatry in the management of mental illness, as there is a current lack of scientific evidence to draw any conclusions. However, there exists a strong hypothesis that telepsychiatric treatment yields the same results as the traditional, in-person therapy and that telepsychiatry is a useful alternative when traditional therapy is not possible. Countries with substantial numbers of refugees living in resource-constrained areas, such as camps, should be encouraged to develop telepsychiatry programs.
