In resource-constrained settings where the neonatal mortality rate (NMR) is high due to preventable causes and health systems are underused, community-based interventions can increase newborn survival by improving health care practices.
To develop and evaluate the effectiveness of a community-based maternal and newborn care services package to reduce perinatal and neonatal mortality in rural Pakistan.
DESIGN, SETTING, AND PARTICIPANTS: This cluster randomized clinical trial was conducted between November 1, 2012, and December 31, 2013, in district Rahim Yar Khan in the province of Punjab. A cluster was defined as an administrative union council. Any consenting pregnant resident of the study area, regardless of gestational age, was enrolled. An ongoing pregnancy surveillance system identified 12 529 and 12 333 pregnancies in the intervention and control clusters, respectively; 9410 pregnancies were excluded from analysis due to continuation of pregnancy at the end of the study, loss to follow-up, or miscarriage. Participants were followed up until the 40th postpartum day. Statistical analysis was performed from January to May 2014.
A maternal and newborn health pack, training for community- and facility-based health care professionals, and community mobilization through counseling and education sessions.
The primary outcome was perinatal mortality, defined as stillbirths per 1000 births and neonatal death within 7 days per 1000 live births. The secondary outcome was neonatal mortality, defined as death within 28 days of life per 1000 live births. Systematic random sampling was used to allocate 10 clusters each to intervention and control groups. Analysis was conducted on a modified intention-to-treat basis.
For the control group vs the intervention group, the total number of households was 33 188 vs 34 315, the median number of households per cluster was 3092 (IQR, 3018-3467) vs 3469 (IQR, 3019-4075), the total population was 229 155 vs 234 674, the mean (SD) number of residents per household was 6.9 (9.5) vs 6.8 (9.6), the number of males per 100 females (ie, the sex ratio) was 104.2 vs 103.7, and the mean (SD) number of children younger than 5 years per household was 1.0 (4.2) vs 1.0 (4.3). Altogether, 7598 births from conrol clusters and 8017 births from intervention clusters were analyzed. There was no significant difference in perinatal mortality between the intervention and control clusters (rate ratio, 0.86; 95% CI, 0.69-1.08; P = .19). The NMR was lower among the intervention than the control clusters (39.2/1000 live births vs 52.2/1000 live births; rate ratio, 0.75; 95% CI, 0.58-0.95; P = .02). The frequencies of antenatal visits and facility births were similar between the 2 groups. However, clean delivery practices were higher among intervention clusters than control clusters (63.2% [2284 of 3616] vs 13.2% [455 of 3458]; P < .001). Chlorhexidine use was also more common among intervention clusters than control clusters (55.9% [4271 of 7642] vs 0.3% [19 of 7203]; P < .001).
This pragmatic cluster randomized clinical trial demonstrated a reduction in NMR that occurred in the background of improved household intrapartum and newborn care practices. However, the effect of the intervention on antenatal visits, facility births, and perinatal mortality rates was inconclusive, highlighting areas requiring further research. Nevertheless, the improvement in NMR underscores the effectiveness of community-based programs in low-resource settings.

在资源有限的环境中,由于可预防的原因,新生儿死亡率(NMR)较高,并且卫生系统利用不足,基于社区的干预措施可以通过改善医疗保健实践来提高新生儿的生存率。
制定并评估一种基于社区的母婴保健服务包,以降低巴基斯坦农村地区的围产期和新生儿死亡率。
设计、地点和参与者:这是一项在旁遮普省拉希姆亚尔汗地区于 2012 年 11 月 1 日至 2013 年 12 月 31 日进行的集群随机临床试验。集群定义为一个行政联盟理事会。任何同意参加研究地区的孕妇,无论其孕龄如何,都被纳入研究。一个正在进行的妊娠监测系统分别在干预组和对照组中识别出 12529 次和 12333 次妊娠;由于研究结束时继续妊娠、失访或流产,9410 次妊娠被排除在分析之外。参与者被随访至产后第 40 天。统计分析于 2014 年 1 月至 5 月进行。
产妇和新生儿健康包、社区和医疗机构卫生保健专业人员培训以及通过咨询和教育会议进行社区动员。
主要结局是围产期死亡率,定义为每 1000 例活产中死产的比例和每 1000 例活产中新生儿在 7 天内死亡的比例。次要结局是新生儿死亡率,定义为每 1000 例活产中 28 天内死亡的比例。系统随机抽样用于将每组 10 个集群分配给干预组和对照组。分析采用修改后的意向治疗原则进行。
对于对照组和干预组,对照组的家庭总数为 33188 个,干预组为 34315 个,每个集群的中位数家庭数为 3092(IQR,3018-3467),干预组为 3469(IQR,3019-4075),总人数为 229155 人,对照组为 234674 人,每个家庭的居民平均(SD)数为 6.9(9.5),对照组为 6.8(9.6),男性与女性的比例(即性别比例)为 104.2,对照组为 103.7,对照组为 103.7,每个家庭中 5 岁以下儿童的平均(SD)数为 1.0(4.2),对照组为 1.0(4.3)。共有 7598 例来自对照组的分娩和 8017 例来自干预组的分娩进行了分析。干预组和对照组之间的围产期死亡率没有显著差异(比率比,0.86;95%CI,0.69-1.08;P=0.19)。干预组的 NMR 低于对照组(39.2/1000 活产,52.2/1000 活产;比率比,0.75;95%CI,0.58-0.95;P=0.02)。两组之间的产前检查和医院分娩的频率相似。然而,干预组的清洁分娩做法高于对照组(63.2%[3616 例中的 2284 例],13.2%[3458 例中的 455 例];P<0.001)。干预组中使用洗必泰的情况也多于对照组(55.9%[7642 例中的 4271 例],0.3%[7203 例中的 19 例];P<0.001)。
这项实用的集群随机临床试验表明,在改善家庭分娩和新生儿护理实践的背景下,NMR 有所降低。然而,干预措施对产前检查、医院分娩和围产期死亡率的影响尚无定论,这突出了需要进一步研究的领域。尽管如此,NMR 的改善强调了在资源有限的环境中开展基于社区的计划的有效性。
