Barriers to accessing mental health care for refugees and asylum seekers in high-income countries: A scoping review of reviews mapping demand and supply-side factors onto a conceptual framework

This study undertakes a scoping review of reviews on barriers to accessing mental health care for refugees and asylum seekers in high-income countries. By assessing mental health care access using the Levesque's conceptual framework, we identify barriers along the patient care pathway and highlight research gaps. Following PRISMAScR guidelines, 10 relevant systematic and scoping reviews were identified and analyzed. Seven common barriers were identified, that could be located across different stages of the conceptual framework. Demand-side barriers included: (1) refugees' understanding of mental illness, (2) fear of stigma, (3) lack of awareness of services, (4) attitudes towards formal treatment; while supply-side barriers comprised: (5) language barriers, (6) practical and structural issues, and (7) providers' attitudes and competence. There was a focus on demand-side barriers as key determinants for low service use. We observed a paucity of quantitative studies linking barriers and indicators of access to care. In the context of well-established mental health care systems, previous research has largely explained low access through peculiarities of refugees and asylum seekers, thereby neglecting the role of supplyside factors (including system structures and attitudes of service providers). We discuss how future research can critically question prevailing assumptions and contribute to rigorous evidence.
