INTRODUCTION: Somali-born women comprise a large group of immigrant women of childbearing age in Sweden, with increased risks for perinatal morbidity and mortality and poor experiences of care, despite the goal of providing equitable healthcare for the entire population. Rethinking how care is provided may help to improve outcomes.

OVERALL AIM: To develop and test the acceptability, feasibility and immediate impacts of group antenatal care for Somali-born immigrant women, in an effort to improve experiences of antenatal care, knowledge about childbearing and the Swedish healthcare system, emotional well-being and ultimately, pregnancy outcomes. This protocol describes the rationale, planning and development of the study.

METHODS AND ANALYSIS: An intervention development and feasibility study. Phase I includes needs assessment and development of contextual understanding using focus group discussions. In phase II, the intervention and evaluation tools, based on core values for quality care and person-centred care, are developed. Phase III includes the historically controlled evaluation in which relevant outcome measures are compared for women receiving individual care (2016-2018) and women receiving group antenatal care (2018-2019): care satisfaction (Migrant Friendly Maternity Care Questionnaire), emotional well-being (Edinburgh Postnatal Depression Scale), social support, childbirth fear, knowledge of Swedish maternity care, delivery outcomes. Phase IV includes the process evaluation, investigate process, feasibility and mechanisms of impact using field notes, observations, interviews and questionnaires. All phases are conducted in collaboration with a stakeholder reference group.

ETHICS AND DISSEMINATION: The study is approved by the Regional Ethical Review Board, Stockholm, Sweden. Participants receive information about the study and their right to decline/withdraw without consequences. Consent is given prior to enrolment. Findings will be disseminated at antenatal care units, national/international conferences, through publications in peer-reviewed journals, seminars involving stakeholders, practitioners, community and via the project website. Participating women will receive a summary of results in their language.
