Ethiopia is one of the five nations that bear the global burden of nearly 50% maternal mortalities and newborn deaths. Cause-specific maternal mortality and newborn death information are vitally important for prevention, but little is known about the causes of deaths. Many maternal mortalities and newborn deaths occur at home, outside the formal health sector, and few are attended by qualified medical professionals. Despite the fact that, non-medical factors are often more important in determining whether a woman/newborn lives or dies than the medical cause of death itself. This study determines and explores factors contributing to maternal mortalities and newborn deaths in Ethiopia with the aim of developing a community-based model for averting maternal mortalities and newborn deaths in Ethiopia. The study was organised in three phases. In Phase 1, a community-based-retrospective approach using explorative, descriptive and contextual study design, combining both qualitative and quantitative methods (mixed methods) were used to make an in-depth investigation and analysis of the circumstances and events surrounding individual cases of maternal mortality and newborn deaths. The result of the study revealed various direct and indirect as well as possible contributing factors to maternal mortalities and newborn deaths which outlined bases for forwarding Phase 2 of the study called concept analysis. In Phase 3, a prototype model was developed according to Chinn and Kramer’s approach to theory generation: initially, based on the empirical perspectives of the study, concept analysis was conducted. The structure and process of a model to avert maternal mortality and newborn death were described; and, six survey list; namely, agent, recipient, context, procedure, dynamic and terminus of Dickoff, James and Wiedenbach (1968) form the basis for development and description of a model for averting maternal mortality and newborn deaths in Ethiopia. Impediment in receiving prompt, adequate and appropriate care were common problems encountered even after reaching an appropriate medical facility. For any attempt to attain a significant reduction in maternal mortality and newborn death, the health care system in Ethiopia must assume its tasks to institute critical changes in both the structure and process of health care delivery services. / Health Studies / D.
