Obesity, high blood pressure, smoking and advanced maternal age are all known to be risk factors for stillbirths, making some preventable. In a separate paper in the series, Zulfiqar Bhutta at Aga Khan University in Karachi, Pakistan and colleagues highlighted 10 interventions that, if implemented, could cut the global number of still births by around half.
The interventions include folic acid supplementation before and during pregnancy, detection and treatment of syphilis, prevention of malaria and improved obstetric care. “None of these interventions are remarkably new science,” says Lawn.
An additional study by Robert Pattinson at the University of Pretoria in South Africa and his colleagues comes to the conclusion that such interventions would cost a mere $2.32 per person per year – a small price to pay to avoid the grief and devastation associated with stillbirths.
Worldwide, 2·65 million (uncertainty range 2·08 million to 3·79 million) stillbirths occur yearly, of which 98% occur in countries of low and middle income. Despite the fact that more than 45% of the global burden of stillbirths occur intrapartum, the perception is that little is known about effective interventions, especially those that can be implemented in low-resource settings. We undertook a systematic review of randomised trials and observational studies of interventions which could reduce the burden of stillbirths, particularly in low-income and middle-income countries. We identified several interventions with sufficient evidence to recommend implementation in health systems, including periconceptional folic acid supplementation or fortification, prevention of malaria, and improved detection and management of syphilis during pregnancy in endemic areas. Basic and comprehensive emergency obstetric care were identified as key effective interventions to reduce intrapartum stillbirths. Broad-scale implementation of intervention packages across 68 countries listed as priorities in the Countdown to 2015 report could avert up to 45% of stillbirths according to a model generated from the Lives Saved Tool. The overall costs for these interventions are within the general estimates of cost-effective interventions for maternal care, especially in view of the effects on outcomes across maternal, fetal, and neonatal health.
The causes of stillbirths are inseparable from the causes of maternal and neonatal deaths. This report focuses on prevention of stillbirths by scale-up of care for mothers and babies at the health-system level, with consideration for effects and cost. In countries with high mortality rates, emergency obstetric care has the greatest effect on maternal and neonatal deaths, and on stillbirths. Syphilis detection and treatment is of moderate effect but of lower cost and is highly feasible. Advanced antenatal care, including induction for post-term pregnancies, and detection and management of hypertensive disease, fetal growth restriction, and gestational diabetes, will further reduce mortality, but at higher cost. These interventions are best packaged and provided through linked service delivery methods tailored to suit existing health-care systems. If 99% coverage is reached in 68 priority countries by 2015, up to 1·1 million (45%) third-trimester stillbirths, 201 000 (54%) maternal deaths, and 1·4 million (43%) neonatal deaths could be saved per year at an additional total cost of US$10·9 billion or $2·32 per person, which is in the range of $0·96—2·32 for other ingredients-based intervention packages with only recurrent costs.
