Global Trends in Maternal Mortality and Efforts to Improve Maternal Outcomes Through Sociomedical Interventions

Maternal mortality continues to be a major global health concern that disproportionately affects low- and middle-income countries (LMICs), with the World Health Organisation (WHO) estimating a maternal death occurring every two minutes. The data-sparse LMICs employ a multitude of estimation approaches to gauge maternal mortality ratios (MMR); however, their classification of deaths and reproducibility of estimates remain open to discussion. Despite a considerable reduction of MMR levels since 2000, more recently, the MMR levels in countries including the US have resurged due to the sociomedical crises brought about by the COVID-19 pandemic. The United Nations' Sustainable Development Goal (SDG) 3.1 aims to achieve global maternal mortality ratios of less than 70 per 100,000 live births and below 140 per 100,000 live births at the national level by 2030. However, recent projections indicate it will remain unmet by a margin of a million maternal deaths. Many LMICs apply the three-delays framework of maternal deaths that requires verbal autopsy to be used in tandem with the identification of maternal deaths. The three-delays model devised in the mid-1990s allows LMICs to gear their resources towards specific intervention points. A significant portion of the existing literature has focused on the description of the magnitude of the issue and the factors precipitating maternal deaths. Innovative solutions have recently been implemented, such as repurposing military helicopters to reduce the delays in managing obstetric complications. Similarly, prospective studies are required to devise ways to address the sociomedical mechanisms underlying maternal deaths.
