Developing and evaluating human-centered design solutions for enhancing maternal health service utilization among vulnerable pregnant women in Oromia, Ethiopia: Study protocol for a quasi-experimental study.

Abstract

Background: Disproportionate uptake of and access to maternal and child health services remain significant challenges across and within countries. Differing geographic, economic, environmental, and social factors contribute to varying degrees of vulnerabilities among individuals, which manifest as disparities in maternal and newborn health outcomes. Designing solutions according to need is vital to improve maternal and child health outcomes. In this paper, we describe our study protocol on developing and evaluating the effectiveness of human-centered design (HCD) solutions to improve maternal health service uptake among vulnerable pregnant women in rural areas of Ethiopia.

Methods: The study has two distinct phases. In Phase 1, HCD solutions were developed through co-design workshops with vulnerable pregnant women and key stakeholders. Final solutions included home visit education, audio programs promoting couple discussion, and print materials, implemented in collaboration with community health workers and health officers. A community-based, quasi-experimental, mixed-method study design was used to assess differences between intervention and control arms. A panel sample was enrolled after screening for pregnancy and vulnerability level and surveyed at baseline and midline in Phase 1. Phase 2 adopts an identical design approach with a focus on refining Phase 1 solutions. Newly recruited pregnant women will receive refined solutions for six months, which will be evaluated using post-only end-line surveys and in-depth interviews.

Conclusions and implications: Our sequential approach to evaluating initial solutions, which in turn will inform the enhancement of solutions, will provide practical insights into how solutions are accepted among vulnerable women and how they can be better integrated into women's lives and health systems. This will inform equity-focused practice and policies targeting populations experiencing greater barriers to accessing care and provide insights into system strengthening in rural areas. Our findings will be disseminated to the Ethiopian Ministry of Health and its partners to inform large-scale implementation at the national level.
