ABSTRACT BACKGROUND፡ There is conflicting data on the rate and trends of maternal mortality in Ethiopia. There is no previous study done on the magnitude and trends of maternal death at Saint Paul's Hospital, an institution providing the largest labor and delivery services in Ethiopia. The objective of this study is  to determine the magnitude, causes and contributing factors for maternal deaths in the institution.METHODS: We conducted a retrospective review of maternal deaths from January 2016 to December 2017. Data were analyzed using SPSS version 20.RESULTS: The maternal mortality ratio of the institution was 228.3 per 100,000 live births. Direct maternal death accounted for 90% (n=36) of the deceased. The leading causes of the direct maternal deaths were hypertensive disorders of pregnancy (n=13, 32.5%), postpartum hemorrhage (n=10, 25%), sepsis (n=4, 10%), pulmonary thromboembolism (n=3, 7.5%) and amniotic fluid embolism (n=3, 7.5%).CONCLUSION: The maternal mortality ratio was lower than the ratios reported from other institutions in Ethiopia. Hypertensive disorders of pregnancy and malaria were the leading cause of direct and indirect causes of maternal deaths respectively. Embolism has become one of the top causes of maternal death in a rate like the developed nations. This might show the double burden of embolism and other causes of maternal mortality that developing countries might be facing.KEYWORDS: maternal mortality, maternal death, Ethiopia
