The burden of maternal and neonatal mortality remains persistently high in Nigeria. Sepsis contributes significantly to both maternal and newborn mortality, and safe delivery kits have long been promoted as a cost-effective intervention to ensure hygienic delivery practices and reduce sepsis. However, there is limited evidence on the effectiveness of home birth kit distribution by community health workers, and particularly the impact of this intervention on health outcomes. This paper reports a secondary analysis of data from a cluster randomized trial in rural northern Nigeria in which birth kits were distributed by community health workers to pregnant women in their homes, analyzing non-experimental variation in receipt and use of birth kits. More specifically, associations between pregnant women's baseline characteristics and receipt and use of birth kits, and associations between birth kit use, care utilization and maternal and newborn outcomes were assessed.
Baseline, post-birth and endline data related to 3,317 births observed over a period of three years in 72 intervention communities in Jigawa state, Nigeria, were analyzed using hierarchical, logistic regression models. In total, 140 women received birth kits, and 72 women used the kits. There were no associations between baseline demographic characteristics, health history, and knowledge and attitudes and receipt of a kit, suggesting that community health workers did not systematically target the distribution of birth kits. However, women who used the kit reported reduced odds of past pregnancy complications (OR = 0.44, 95% CI: 0.19-1.00) as well as significantly higher odds of feeling generally healthy at baseline (OR = 2.00, 95% CI: 1.06-3.76), of exposure to radio media (OR = 1.97, 95% CI: 1.21-3.22), and of perceiving themselves as having a low-risk pregnancy (OR = 3.05, 95% CI:1.39-6.68). While there were no significant associations between birth kit use and facility based delivery, skilled birth attendance or post-natal care, women who used a kit exhibited significantly lower odds of completing four or more ANC visits (adjusted OR = 0.39, 95% CI: 0.18-0.85) and significantly higher odds of reporting prolonged labor (adjusted OR = 4.75, 95% CI: 1.36-16.59), and post-partum bleeding (adjusted OR = 3.25, 95% CI: 1.11-9.52).
This evidence suggests that use of birth kits is low in a rural population characterized by minimal baseline utilization of maternal and neonatal health services, and the use of birth kits was not associated with reductions in maternal or neonatal morbidity. While further research is required to understand how the effectiveness of birth kits may be shaped by the mechanism through which women access and utilize the kits, our findings suggest that the provision of kits to women outside of the formal health system may be associated with increased risk of adverse outcomes.
在尼日利亚,孕产妇和新生儿死亡率仍然居高不下。败血症对孕产妇和新生儿死亡率都有重大影响,安全分娩套件长期以来一直被宣传为一种具有成本效益的干预措施,以确保卫生分娩实践并减少败血症。然而,关于社区卫生工作者分发家庭分娩套件的有效性,特别是这种干预措施对健康结果的影响,证据有限。本文报告了对尼日利亚北部农村进行的一项集群随机试验的二次分析,其中社区卫生工作者向家中的孕妇分发了分娩套件,分析了接受和使用分娩套件的非实验性变化。更具体地说,评估了孕妇的基线特征与接受和使用分娩套件之间的关系,以及分娩套件的使用、护理利用与孕产妇和新生儿结局之间的关系。
在尼日利亚吉加瓦州的 72 个干预社区进行了为期三年的研究,共观察到 3317 次分娩,分析了与这期间相关的基线、产后和期末数据,使用了分层逻辑回归模型。共有 140 名妇女收到了分娩套件,72 名妇女使用了套件。基线人口统计学特征、健康史、知识和态度与套件的接收和使用之间没有关联,这表明社区卫生工作者没有系统地针对分娩套件的分配。然而,使用套件的妇女报告过去妊娠并发症的几率降低(OR = 0.44,95%CI:0.19-1.00),并且在基线时感到身体健康的几率显著增加(OR = 2.00,95%CI:1.06-3.76),接触广播媒体的几率增加(OR = 1.97,95%CI:1.21-3.22),并且认为自己处于低风险妊娠的几率增加(OR = 3.05,95%CI:1.39-6.68)。虽然套件的使用与医疗机构分娩、熟练助产士分娩或产后护理之间没有显著关联,但使用套件的妇女完成 4 次或更多次 ANC 就诊的几率明显降低(调整后的 OR = 0.39,95%CI:0.18-0.85),并且报告延长产程的几率显著增加(调整后的 OR = 4.75,95%CI:1.36-16.59),以及产后出血(调整后的 OR = 3.25,95%CI:1.11-9.52)。
这一证据表明,在一个产妇和新生儿健康服务利用程度极低的农村地区,分娩套件的使用率很低,而且套件的使用与产妇或新生儿发病率的降低无关。虽然需要进一步研究来了解妇女获取和使用套件的机制如何影响套件的效果,但我们的研究结果表明,在正规卫生系统之外向妇女提供套件可能与不良结局的风险增加有关。
