Abstract Background ORAMMA is a European capacity-building project (GR, NL, UK) for pregnant migrant, asylum-seeking and refugee (MAR) women to improve maternal and newborn outcomes. ORAMMA is an operational and strategic approach for mother-centred, community-oriented, gender-sensitive, interdisciplinary and compassionate care, to meet the needs of MAR women in Europe. Objectives ORAMMA developed training for midwives and other primary health and social care (PC) professionals to meet the needs of MAR women. Methodology comprised three phases: evidence synthesis and needs assessment, training material development, and community enablement through locally recruited women in the innovative role of Maternal Peer Supporters (MPSs). Results Needs assessment highlighted the need to train ORAMMA’s teams of midwives and other PC professionals to care for women who suffered undue hardship, oftentimes leading to PTSD, i.e., victims of trafficking, rape, underage women, sufferers of acute or chronic conditions, and sole family carers. The experiences encountered informed curriculum development for midwives and other PC professionals. Interprofessional training for integrated perinatal care delivery was developed for and delivered in three phases, i.e., detection of pregnancy (GP coordination), care during pregnancy (midwive coordination), and support after birth (social worker coordination), with special modules developed in a participatory manner on: migration status and policies, maternity care for MAR women, and communication and culturally sensitive practices. Conclusions Training midwives and other PC professionals along with members of MAR communities in the MPS role was identified to be a key element to efficiently support women and their families, to propagate key perinatal and public health messages, and to advocate for the rights of MAR women to ensure access equity to quality care in a highly responsive manner. ORAMMA’s tools are available in easily accessible platform online. Key messages ORAMMA developed multilingual material to meet the needs of PC professionals and of MAR women, in an innovative manner and with high relevance for cross-border knowledge transfer. ORAMMA addressed key aspects in delivery and access, focusing on cultural awareness and communication; its relevance extends well beyond perinatal care to improved family outcomes and public health.
