MOMENTUM Safe Surgery in Family Planning and Obstetrics is a global project that strengthens surgical ecosystems through partnership with country institutions. In Nigeria, the project implements in Bauchi, Ebonyi, Kebbi and Sokoto states and the Federal Capital Territory, focusing on surgical obstetrics, holistic fistula care and female genital mutilation/cutting prevention and care. The project utilized participatory approaches during its design, planning and early implementation phases. Well-established state and national systems, structures, policies and guidelines enable this programming approach. Since communication between institutional actors is often limited, these approaches necessitate building and maintaining relationships and knowledge sharing, which requires a significant up-front time investment that must be balanced with donor/partner desires for rapid deliverables. Linking different actors within the health system together through co-creation/co-implementation represents a crucial step in building sustainable country ownership and oversight for surgical ecosystems strengthening interventions.
