Introduction:In Ethiopia, rural residence and limited access to skilled providers and health services pose challenges for maternal and newborn survival. The Maternal Health in Ethiopia Partnership (MaNHEP) developed a community-based model of maternal and newborn health focusing on birth and the early postnatal period and positioned it for scale-up. MaNHEP's 3-pronged intervention included community-and facility-based community maternal and newborn health training, continuous quality improvement, and behavior change communications.Methods: Evaluation included baseline and endline surveys conducted with random samples of health extension workers, community health development agents, traditional birth attendants (TBAs), and women who gave birth the year prior to the survey; pretraining, posttraining, and postintervention clinical skills assessments conducted with health extension workers, community health development agents, and traditional birth attendants; endline surveys conducted with quality improvement teams; and a perinatal verbal autopsy study.Results: There were significant improvements in the completeness of maternal and newborn health care provided by the team of health extension workers, community health development agents, and TBAs in their demonstrated capacity and confidence to provide care and a sense of being part of a maternal and newborn health care team. There were also significant improvements in women's awareness of and trust in the ability of these team members to provide maternal and newborn health care, in the completeness of care that women received, and in the use of skilled providers and health extension workers for antenatal and postnatal care. In addition, a shift occurred toward the use of providers with a higher level of skills for birth care. Successful local solutions for pregnancy identification, antenatal care registration, labor-birth notification, and postnatal follow-up were adopted across 51 project communities. The number of days between perinatal deaths increased over the duration of the project.Discussion: MaNHEP was associated with more, and more complete, coverage of maternal and newborn health care and improved perinatal outcomes.
