Why is Bangladesh lagging far behind the target of maternal mortality?

It is worrying that Bangladesh still lags behind the target of maternal mortality by a huge margin, though the mortality rate is slightly decreasing over the years. Death of a woman during pregnancy, parturition, and within 42 days of giving birth is considered as maternal mortality.
According to a recent report by WHO, UNICEF, UNFPA, World Bank Group and UNDESA/Population Division, the maternal mortality rate has decreased by 72 percent in the last 20 years and still ten women are dying every day due to complexities regarding child birth. It said 123 women died in 2020 against the birth of every 100,000 children. The decrease rate of maternal mortality is only 6.5 every year. But this is not enough. The WHO has identified several factors that include bleeding, high blood pressure, and infection during pregnancy, complexities due to unsafe abortion and conditions like HIV/AIDS and malaria as the prime causes of maternal mortality.
This report also does not prove that Bangladesh is in a better position in terms of providing better maternal healthcare. However, both Pakistan and Afghanistan are behind Bangladesh in almost all the indices related to human resources and healthcare. But the question is why would we remain behind India, Maldives, Bhutan and Sri Lanka? The UN and several other international family planning and healthcare providers have put emphasis on increasing investment on an emergency basis to get rid of the situation. It is feared that there would be no trained midwife for safe child delivery, if investment is not increased immediately.
It would be possible to bring down the maternal mortality rate to the target rate if better healthcare is ensured for all the citizens across the country. The Sustainable Development Goals (SDGs) target will be beyond reach if the concerned ministry does not take effective steps. Only to improve facilities and staff, and supply them adequately will help achieve the SDG target.
