Abstract

Background

Of the global burden of 2.6 million stillbirths, around 1.2 million occur during labour i.e. are intrapartum deaths. In low-/middle-income countries, a significant proportion of women give birth at home, usually in the absence of a skilled birth attendant. This review discusses the impact of skilled birth attendance (SBA) and the provision of Emergency Obstetric Care (EOC) on stillbirths and perinatal mortality.

Methods

A systematic literature search was performed on PubMed/MEDLINE, Cochrane Database and the WHO regional libraries. Data of all eligible studies were extracted into a standardized Excel sheet containing variables such as participants’ characteristics, sample size, location, setting, blinding, allocation concealment, intervention and control details and limitations. We undertook a meta-analysis of the impact of SBA on stillbirths. Given the paucity of data from randomized trials or robust quasi-experimental designs, we undertook an expert Delphi consultation to determine impact estimates of provision of Basic and Comprehensive EOC on reducing stillbirths if there would be universal coverage (99%).

Results

The literature search yielded 871 hits. A total of 21 studies were selected for data abstraction. Our meta-analysis on community-based skilled birth attendance based on two before-after studies showed a 23% significant reduction in stillbirths (RR = 0.77; 95% CI: 0.69 – 0.85). The overall quality grade of available evidence for this intervention on stillbirths was ‘moderate’. The Delphi process supported the estimated reduction in stillbirths by skilled attendance and experts further suggested that the provision of Basic EOC had the potential to avert intrapartum stillbirths by 45% and with provision of Comprehensive EOC this could be reduced by 75%. These estimates are conservative, consistent with historical trends in maternal and perinatal mortality from both developed and developing countries, and are recommended for inclusion in the Lives Saved Tool (LiST) model.

Conclusions

Both Skilled Birth Attendance and Emergency/or Essential Obstetric Care have the potential to reduce the number of stillbirths seen globally. Further evidence is needed to be able to calculate an effect size.

No cry at birth: global estimates of intrapartum stillbirths and intrapartum-related neonatal deaths.

Joy E. Lawn, Kenji Shibuya, Claudia Stein (2005)

Fewer than 3% of 4 million annual neonatal deaths occur in countries with reliable vital registration (VR) data. Global estimates for asphyxia-related neonatal deaths vary from 0.7 to 1.2 million. Estimates for intrapartum stillbirths are not available. We aimed to estimate the numbers of intrapartum-related neonatal deaths and intrapartum stillbirths in the year 2000. Sources of data on neonatal death included: vital registration (VR) data on neonatal death from countries with full (> 90%) VR coverage (48 countries, n = 97,297); studies identified through literature searches (> 4000 abstracts) and meeting inclusion criteria (46 populations, 30 countries, n = 12,355). A regression model was fitted to cause-specific proportionate mortality data from VR and the literature. Predicted cause-specific proportions were applied to the number of neonatal deaths by country, and summed to a global total. Intrapartum stillbirths were estimated using median cause-specific mortality rate by country (73 populations, 52 countries, n = 46,779) or the subregional median in the absence of country data. Intrapartum-related neonatal deaths were estimated at 0.904 million (uncertainty 0.65-1.17), equivalent to 23% of the global total of 4 million neonatal deaths. Country-level model predictions compared well with population-based data sets not included in the input data. An estimated 1.02 million intrapartum stillbirths (0.66-1.48 million) occur annually, comprising 26% of global stillbirths. Intrapartum-related neonatal deaths account for almost 10% of deaths in children aged under 5 years. Intrapartum stillbirths are a huge and invisible problem, but are potentially preventable. Programmatic attention and improved information are required.

Standards for CHERG reviews of intervention effects on child survival

Neff Walker, Christa Fischer-Walker, Jennifer Bryce … (2010)

Background The Lives Saved Tool (LiST) uses estimates of the effects of interventions on cause-specific child mortality as a basis for generating projections of child lives that could be saved by increasing coverage of effective interventions. Estimates of intervention effects are an essential element of LiST, and need to reflect the best available scientific evidence. This article describes the guidelines developed by the Child Health Epidemiology Reference Group (CHERG) that are applied by scientists conducting reviews of intervention effects for use in LiST. Methods The guidelines build on and extend those developed by the Cochrane Collaboration and the Working Group for Grading of Recommendations Assessment, Development and Evaluation (GRADE). They reflect the experience gained by the CHERG intervention review groups in conducting the reviews published in this volume, and will continue to be refined through future reviews. Presentation of the guidelines Expected products and guidelines are described for six steps in the CHERG intervention review process: (i) defining the scope of the review; (ii) conducting the literature search; (iii) extracting information from individual studies; (iv) assessing and summarizing the evidence; (v) translating the evidence into estimates of intervention effects and (vi) presenting the results. Conclusions The CHERG intervention reviews represent an ambitious effort to summarize existing evidence and use it as the basis for supporting sound public health decision making through LiST. These efforts will continue, and a similar process is now under way to assess intervention effects for reducing maternal mortality.

60 Million non-facility births: who can deliver in community settings to reduce intrapartum-related deaths?

Gary Darmstadt, Anne C C Lee, Simon Cousens … (2009)

For the world's 60 million non-facility births, addressing who is currently attending these births and what effect they have on birth outcomes is a key starting point toward improving care during childbirth. We present a systematic review of evidence for the effect of community-based cadres-community-based skilled birth attendants (SBAs), trained traditional birth attendants (TBAs), and community health workers (CHWs)-in improving perinatal and intrapartum-related outcomes. The evidence for providing skilled birth attendance in the community is low quality, consisting of primarily before-and-after and quasi-experimental studies, with a pooled 12% reduction in all cause perinatal mortality (PMR) and a 22%-47% reduction in intrapartum-related neonatal mortality (IPR-NMR). Low/moderate quality evidence suggests that TBA training may improve linkages with facilities and improve perinatal outcomes. A randomized controlled trial (RCT) of TBA training showed a 30% reduction in PMR, and a meta-analysis demonstrated an 11% reduction in IPR-NMR. There is moderate evidence that CHWs have a positive impact on perinatal-neonatal outcomes. Meta-analysis of CHW packages (2 cluster randomized controlled trials, 2 quasi-experimental studies) showed a 28% reduction in PMR and a 36% reduction in early neonatal mortality rate; one quasi-experimental study showed a 42% reduction in IPR-NMR. Skilled childbirth care is recommended for all pregnant women, and community strategies need to be linked to prompt, high-quality emergency obstetric care. CHWs may play a promising role in providing pregnancy and childbirth care, mobilizing communities, and improving perinatal outcomes in low-income settings. While the role of the TBA is still controversial, strategies emphasizing partnerships with the health system should be further considered. Innovative community-based strategies combined with health systems strengthening may improve childbirth care for the rural poor, help reduce gross inequities in maternal and newborn survival and stillbirth rates, and provide an effective transition to higher coverage for facility births.
