High-risk pregnancies, such as twin pregnancies, deserve particular attention as mortality is very high in this group. With a view to inform policy and national guidelines development for the Sustainable Development Goals, we reviewed national training materials, guidelines, and policies underpinning the provision of care in relation to twin pregnancies and assessed care provided to twins in 8 Eastern and Southern African countries: Kenya, Malawi, Mozambique, Rwanda, Tanzania, Uganda, Zambia, and Zimbabwe.
We located policies and guidelines by reviewing national repositories and by contacting experts to systematically map country-level maternal and newborn training materials, guidelines, and policies. We extracted recommendations for care for twins spanning ante-, intra-, and postpartum care that typically should be offered during twin pregnancies and childbirth. We compared care provided for mothers of twins to that provided for mothers of singletons during the ante-, intra-, and postpartum period and computed neonatal mortality rates using the most recent Demographic and Health Surveys (DHS) data for each country. There was a paucity of guidance on care specifically for twin or multiple pregnancies: None of the countries provided clear guidance on additional number of antenatal care visits or specific antenatal content, while 7 of the 8 countries recommended twins to be delivered in a comprehensive emergency obstetric and neonatal care facility. These results were mirrored by DHS results of 73,462 live births (of which 1,360 were twin) indicating that twin pregnancies did not receive more frequent or intensified antenatal care. The percentage of twin deliveries in hospitals varied from 25.3% in Mozambique to 63.0% in Kenya, and women with twin deliveries were between 5 and 27 percentage points more likely to deliver in hospitals compared to women with singleton live births; this difference was significant in 5 of the 8 countries (t test p < 0.05). The percentage of twin deliveries by cesarean section varied from 9% in Mozambique to 36% in Rwanda. The newborn mortality rate among twins, adjusted for maternal age and parity, was 4.6 to 7.2 times higher for twins compared to singletons in all 8 countries.
Despite the limited sample size and the limited number of clinically relevant services evaluated, our study provided evidence that mothers of twins receive insufficient care and that mortality in twin newborns is very high in Eastern and Southern Africa. Most countries have insufficient guidelines for the care of twins. While our data do not allow us to make a causal link between insufficient guidelines and insufficient care, they call for an assessment and reconceptualisation of policies to reduce the unacceptably high mortality in twins in Eastern and Southern Africa.
高危妊娠,如双胞胎妊娠,需要特别关注,因为该组死亡率非常高。为了为可持续发展目标的政策和国家指南制定提供信息,我们审查了与双胞胎妊娠相关的国家培训材料、指南和政策,并评估了 8 个东非和南部非洲国家(肯尼亚、马拉维、莫桑比克、卢旺达、坦桑尼亚、乌干达、赞比亚和津巴布韦)为双胞胎提供的护理。
我们通过审查国家知识库和联系专家,系统地定位了政策和指南,以定位国家一级的孕产妇和新生儿培训材料、指南和政策。我们提取了跨越产前、产中和产后护理的双胞胎护理建议,这些建议通常应在双胞胎妊娠和分娩期间提供。我们比较了双胞胎母亲在产前、产中和产后期间接受的护理与单胎母亲接受的护理,并使用每个国家最近的人口与健康调查( DHS )数据计算了新生儿死亡率。关于双胞胎或多胎妊娠护理的指导很少:8 个国家中没有一个国家提供关于额外产前护理次数或特定产前内容的明确指导,而 7 个国家建议在综合性紧急产科和新生儿护理设施中分娩双胞胎。这一结果反映在 DHS 对 73462 例活产(其中 1360 例为双胞胎)的结果中,表明双胞胎妊娠并未获得更频繁或强化的产前护理。在医院分娩的双胞胎比例从莫桑比克的 25.3%到肯尼亚的 63.0%不等,与单胎活产的妇女相比,分娩双胞胎的妇女在医院分娩的可能性高 5 至 27 个百分点;在 8 个国家中有 5 个国家(t 检验 p < 0.05)存在显著差异。剖腹产分娩的双胞胎比例从莫桑比克的 9%到卢旺达的 36%不等。在调整了母亲年龄和生育次数后,所有 8 个国家的双胞胎新生儿死亡率均比单胎新生儿高 4.6 至 7.2 倍。
尽管样本量有限,评估的临床相关服务数量有限,但我们的研究提供的证据表明,双胞胎母亲接受的护理不足,东非和南部非洲双胞胎新生儿的死亡率非常高。大多数国家对双胞胎护理的指导方针不足。虽然我们的数据不允许我们将指导方针不足与护理不足之间建立因果关系,但它们呼吁评估和重新概念化政策,以降低东非和南部非洲双胞胎不可接受的高死亡率。
