Even with significant achievements, maternal mortality remains a critical concern for Bangladesh. Evidence shows that almost 14 mothers die every day due to complications of pregnancy and child birth in the country. On the other hand, Bangladesh is still among the top 10 countries with the highest burden of under-5 and newborn deaths in the world. So, to achieve sustainable development goal targets 3.1 and 3.2, Bangladesh needs to bring down the maternal mortality rate and neonatal mortality rate respectively. The RDM Activity is carrying out implementation research in the area of maternal and neonatal health to identify and resolve operational challenges to generate evidence of what works and how works.
