BACKGROUND: Migrants have problematic access to health-care; non-institutional organizations (NGOs), as well as institutional bodies may play a role in facilitating their access to mainstream health care. AIM: Our research reviews actions that address the need of migrants in terms of health care in order to understand how, where, and who participates in this effort. METHOD: Data were from desk or web research, declaration from organisations and their websites, information from WHO Country Offices. RESULTS: 154 NGOs were identified in the WHO European Region. 58% were direct health care providers while the remaining provided either mediation services or were part of a network organization. 173 national institutes (GOVs) were found; less than the 20% were directly or indirectly involved in health care, whereas the majority were involved in research, policy development, international relations and human rights. CONCLUSION AND RECOMMENDATION: Some gaps, a certain fragmentation and lack of coordination were identified. WHO can play an overarching role in the exchange of expertise and harmonisation of the efforts in this field.
