Unsafe abortion is estimated to account for 13% of maternal mortality globally. Medical abortion is a safe alternative.
By estimating mortality risks for unsafe and medical abortion and childbirth for Tanzania and Ethiopia, we modelled changes in maternal mortality that are achievable if unsafe abortion were replaced by medical abortion. We selected Ethiopia and Tanzania because of their high maternal mortality ratios (MMRatios) and contrasting situations regarding health care provision and abortion legislation. We focused on misoprostol-only regimens due to the drug's low cost and accessibility. We included the impact of medical abortion on women who would otherwise choose unsafe abortion and on women with unwanted/mistimed pregnancies who would otherwise carry to term.
Thousands of lives could be saved each year in each country by implementing medical abortion using misoprostol (2122 in Tanzania and 2551 in Ethiopia assuming coverage equals family planning services levels: 56% for Tanzania, 31% for Ethiopia). Changes in MMRatios would be less pronounced because the intervention would also affect national birth rates.
This is the first analysis of impact of medical abortion provision which takes into account additional potential users other than those currently using unsafe abortion. Thousands of women's lives could be saved, but this may not be reflected in as substantial changes in MMRatios because of medical abortion's demographic impact. Therefore policy makers must be aware of the inability of some traditional measures of maternal mortality to detect the real benefits offered by such an intervention.
不安全堕胎估计占全球孕产妇死亡的 13%。药物流产是一种安全的替代方法。
通过估计坦桑尼亚和埃塞俄比亚不安全堕胎和分娩的死亡率以及药物流产的死亡率,我们模拟了如果不安全堕胎被药物流产取代,孕产妇死亡率可以降低多少。我们选择坦桑尼亚和埃塞俄比亚是因为它们的孕产妇死亡率高,以及在医疗保健提供和堕胎立法方面的情况截然不同。我们专注于米索前列醇方案,因为这种药物成本低且易于获得。我们还考虑了药物流产对那些选择不安全堕胎的妇女以及那些选择不想要/不合时宜怀孕并希望继续妊娠的妇女的影响。
在每个国家,通过使用米索前列醇实施药物流产,每年可以挽救数千人的生命(假设覆盖率等于计划生育服务水平:坦桑尼亚为 56%,埃塞俄比亚为 31%,则在坦桑尼亚可挽救 2122 条生命,在埃塞俄比亚可挽救 2551 条生命)。由于干预措施也会影响国家的出生率,因此孕产妇死亡率比数的变化不会太明显。
这是首次分析药物流产提供的影响,该分析考虑了除目前使用不安全堕胎的妇女之外的其他潜在使用者。成千上万的妇女的生命可以得到挽救,但由于药物流产的人口统计学影响,孕产妇死亡率比数的变化可能不会那么显著。因此,决策者必须意识到,一些传统的孕产妇死亡率衡量标准无法检测到这种干预措施带来的真正好处。
