BACKGROUND: Many interventions have been implemented to improve maternal health outcomes in sub-Saharan Africa (SSA). Currently, however, systematic information on the effectiveness of these interventions remains scarce. We conducted a systematic review of published evidence on non-drug interventions that reported effectiveness in improving outcomes and quality of care in maternal health in SSA.
METHODS: African Journals Online, Bioline, MEDLINE, Ovid, Science Direct, and Scopus databases were searched for studies published in English between 2000 and 2015 and reporting on the effectiveness of interventions to improve quality and outcomes of maternal health care in SSA. Articles focusing on interventions that involved drug treatments, medications, or therapies were excluded. We present a narrative synthesis of the reported impact of these interventions on maternal morbidity and mortality outcomes as well as on other dimensions of the quality of maternal health care (as defined by the Institute of Medicine 2001 to comprise safety, effectiveness, efficiency, timeliness, patient centeredness, and equitability).
RESULTS: Seventy-three studies were included in this review. Non-drug interventions that directly or indirectly improved quality of maternal health and morbidity and mortality outcomes in SSA assumed a variety of forms including mobile and electronic health, financial incentives on the demand and supply side, facility-based clinical audits and maternal death reviews, health systems strengthening interventions, community mobilization and/or peer-based programs, home-based visits, counseling and health educational and promotional programs conducted by health care providers, transportation and/or communication and referrals for emergency obstetric care, prevention of mother-to-child transmission of HIV, and task shifting interventions. There was a preponderance of single facility and community-based studies whose effectiveness was difficult to assess.
CONCLUSIONS: Many non-drug interventions have been implemented to improve maternal health care in SSA. These interventions have largely been health facility and/or community based. While the evidence on the effectiveness of interventions to improve maternal health is varied, study findings underscore the importance of implementing comprehensive interventions that strengthen different components of the health care systems, both in the community and at the health facilities, coupled with a supportive policy environment.

BACKGROUND: While maternal, infant and under-five child mortality rates in developing countries have declined significantly in the past two to three decades, newborn mortality rates have reduced much more slowly. While it is recognised that almost half of the newborn deaths can be prevented by scaling up evidence-based available interventions (such as tetanus toxoid immunisation to mothers, clean and skilled care at delivery, newborn resuscitation, exclusive breastfeeding, clean umbilical cord care, and/or management of infections in newborns), many require facility-based and outreach services. It has also been stated that a significant proportion of these mortalities and morbidities could also be potentially addressed by developing community-based packaged interventions which should also be supplemented by developing and strengthening linkages with the local health systems. Some of the recent community-based studies of interventions targeting women of reproductive age have shown variable impacts on maternal outcomes and hence it is uncertain if these strategies have consistent benefit across the continuum of maternal and newborn care.
OBJECTIVES: To assess the effectiveness of community-based intervention packages in reducing maternal and neonatal morbidity and mortality; and improving neonatal outcomes.
SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (31 May 2014), World Bank's JOLIS (25 May 2014), BLDS at IDS and IDEAS database of unpublished working papers (25 May 2014), Google and Google Scholar (25 May 2014).
SELECTION CRITERIA: All prospective randomised, cluster-randomised and quasi-randomised trials evaluating the effectiveness of community-based intervention packages in reducing maternal and neonatal mortality and morbidities, and improving neonatal outcomes.
DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for inclusion, assessed trial quality and extracted the data. Data were checked for accuracy.
MAIN RESULTS: The review included 26 cluster-randomised/quasi-randomised trials, covering a wide range of interventional packages, including two subsets from three trials. Assessment of risk of bias in these studies suggests concerns regarding insufficient information on sequence generation and regarding failure to adequately address incomplete outcome data, particularly from randomised controlled trials. We incorporated data from these trials using generic inverse variance method in which logarithms of risk ratio (RR) estimates were used along with the standard error of the logarithms of RR estimates.
Our review showed a possible effect in terms of a reduction in maternal mortality (RR 0.80; 95% confidence interval (CI) 0.64 to 1.00, random-effects (11 studies, n = 167,311; random-effects, Tau² = 0.03, I² 20%). However, significant reduction was observed in maternal morbidity (average RR 0.75; 95% CI 0.61 to 0.92; four studies, n = 138,290; random-effects, Tau² = 0.02, I² = 28%); neonatal mortality (average RR 0.75; 95% CI 0.67 to 0.83; 21 studies, n = 302,646; random-effects, Tau² = 0.06, I² = 85%) including both early and late mortality; stillbirths (average RR 0.81; 95% CI 0.73 to 0.91; 15 studies, n = 201,181; random-effects, Tau² = 0.03, I² = 66%); and perinatal mortality (average RR 0.78; 95% CI 0.70 to 0.86; 17 studies, n = 282,327; random-effects Tau² = 0.04, I² = 88%) as a consequence of implementation of community-based interventional care packages.
Community-based intervention packages also increased the uptake of tetanus immunisation by 5% (average RR 1.05; 95% CI 1.02 to 1.09; seven studies, n = 71,622; random-effects Tau² = 0.00, I² = 52%); use of clean delivery kits by 82% (average RR 1.82; 95% CI 1.10 to 3.02; four studies, n = 54,254; random-effects, Tau² = 0.23, I² = 90%); rates of institutional deliveries by 20% (average RR 1.20; 95% CI 1.04 to 1.39; 14 studies, n = 147,890; random-effects, Tau² = 0.05, I² = 80%); rates of early breastfeeding by 93% (average RR 1.93; 95% CI 1.55 to 2.39; 11 studies, n = 72,464; random-effects, Tau² = 0.14, I² = 98%), and healthcare seeking for neonatal morbidities by 42% (average RR 1.42; 95% CI 1.14 to 1.77, nine studies, n = 66,935, random-effects, Tau² = 0.09, I² = 92%). The review also showed a possible effect on increasing the uptake of iron/folic acid supplementation during pregnancy (average RR 1.47; 95% CI 0.99 to 2.17; six studies, n = 71,622; random-effects, Tau² = 0.26; I² = 99%).
It has no impact on improving referrals for maternal morbidities, healthcare seeking for maternal morbidities, iron/folate supplementation, attendance of skilled birth attendance on delivery, and other neonatal care-related outcomes. We did not find studies that reported the impact of community-based intervention package on improving exclusive breastfeeding rates at six months of age. We assessed our primary outcomes for publication bias and observed slight asymmetry on the funnel plot for maternal mortality.
AUTHORS' CONCLUSIONS: Our review offers encouraging evidence that community-based intervention packages reduce morbidity for women, mortality and morbidity for babies, and improves care-related outcomes particularly in low- and middle-income countries. It has highlighted the value of integrating maternal and newborn care in community settings through a range of interventions, which can be packaged effectively for delivery through a range of community health workers and health promotion groups. While the importance of skilled delivery and facility-based services for maternal and newborn care cannot be denied, there is sufficient evidence to scale up community-based care through packages which can be delivered by a range of community-based workers.
BACKGROUND: Progress in maternal survival in sub-Saharan Africa has been poor since the Millennium Declaration.
OBJECTIVES: This systematic review aims to investigate the presence and rigour of evidence for effective capacity building for Essential Obstetric and Newborn Care (EONC) to reduce maternal mortality in rural, sub-Saharan Africa, where maternal mortality ratios are highest globally.
SEARCH STRATEGY: MEDLINE (1990-January 2014), EMBASE (1990-January 2014), and the Cochrane Library were included in our search. Key developing world issues of The Lancet and the British Journal of Obstetrics and Gynaecology, African Ministry of Health websites, and the WHO reproductive health library were searched by hand.
SELECTION CRITERIA: Studies investigating essential obstetric and newborn care packages in basic and comprehensive care facilities, at community and institutional level, in rural sub-Saharan Africa were included. Studies were included if they reported on healthcare worker performance, access to care, community behavioural change, and emergency obstetric and newborn care.
DATA COLLECTION AND ANALYSIS: Data were extracted and all relevant studies independently appraised using structured abstraction and appraisal tools.
MAIN RESULTS: There is moderate evidence to support the training of healthcare workers of differing cadres in the provision of emergency obstetric and newborn services to reduce institutional maternal mortality and case-fatality rates in rural sub-Saharan Africa. Community schemes that sensitise and enable access to maternal health services result in a modest rise in facility birth and skilled birth attendance in this rural setting.
AUTHORS' CONCLUSION: Essential Obstetric and Newborn Care has merit as an intervention package to reduce maternal mortality in rural sub-Saharan Africa.
BACKGROUND: Each year almost 3 million newborns die within the first 28 days of life, 2.6 million babies are stillborn, and 287,000 women die from complications of pregnancy and childbirth worldwide. Effective and cost-effective interventions and behaviours for mothers and newborns exist, but their coverage remains inadequate in low- and middle-income countries, where the vast majority of deaths occur. Cost-effective strategies are needed to increase the coverage of life-saving maternal and newborn interventions and behaviours in resource-constrained settings.
METHODS: A systematic review was undertaken on the cost-effectiveness of strategies to improve the demand and supply of maternal and newborn health care in low-income and lower-middle-income countries. Peer-reviewed and grey literature published since 1990 was searched using bibliographic databases, websites of selected organizations, and reference lists of relevant studies and reviews. Publications were eligible for inclusion if they report on a behavioural or health systems strategy that sought to improve the utilization or provision of care during pregnancy, childbirth or the neonatal period; report on its cost-effectiveness; and were set in one or more low-income or lower-middle-income countries. The quality of the publications was assessed using the Consolidated Health Economic Evaluation Reporting Standards statement. Incremental cost per life-year saved and per disability-adjusted life-year averted were compared to gross domestic product per capita.
RESULTS: Forty-eight publications were identified, which reported on 43 separate studies. Sixteen were judged to be of high quality. Common themes were identified and the strategies were presented in relation to the continuum of care and the level of the health system. There was reasonably strong evidence for the cost-effectiveness of the use of women's groups, home-based newborn care using community health workers and traditional birth attendants, adding services to routine antenatal care, a facility-based quality improvement initiative to enhance compliance with care standards, and the promotion of breastfeeding in maternity hospitals. Other strategies reported cost-effectiveness measures that had limited comparability.
CONCLUSION: Demand and supply-side strategies to improve maternal and newborn health care can be cost-effective, though the evidence is limited by the paucity of high quality studies and the use of disparate cost-effectiveness measures.

INTRODUCTION: Preconception care includes any intervention to optimize a woman's health before pregnancy with the aim to improve maternal, newborn and child health (MNCH) outcomes. Preconception care bridges the gap in the continuum of care, and addresses pre-pregnancy health risks and health problems that could have negative maternal and fetal consequences. It therefore has potential to further reduce global maternal and child mortality and morbidity, especially in low-income countries where the highest burden of pregnancy-related deaths and disability occurs.
METHODS: A systematic review and meta-analysis of the evidence was conducted to ascertain the possible impact of preconception care for adolescents, women and couples of reproductive age on MNCH outcomes. A comprehensive strategy was used to search electronic reference libraries, and both observational and clinical controlled trials were included. Cross-referencing and a separate search strategy for each preconception risk and intervention ensured wider study capture.
RESULTS: Women who received preconception care in either a healthcare center or the community showed improved outcomes, such as smoking cessation; increased use of folic acid; breastfeeding; greater odds of obtaining antenatal care; and lower rates of neonatal mortality.
CONCLUSION: Preconception care is effective in improving pregnancy outcomes. Further studies are needed to evaluate consistency and magnitude of effect in different contexts; develop and assess new preconception interventions; and to establish guidelines for the provision of preconception care.
BACKGROUND: Maternal and neonatal mortality rates remain high in many low-income and middle-income countries. Different approaches for the improvement of birth outcomes have been used in community-based interventions, with heterogeneous effects on survival. We assessed the effects of women's groups practising participatory learning and action, compared with usual care, on birth outcomes in low-resource settings.
METHODS: We did a systematic review and meta-analysis of randomised controlled trials undertaken in Bangladesh, India, Malawi, and Nepal in which the effects of women's groups practising participatory learning and action were assessed to identify population-level predictors of effect on maternal mortality, neonatal mortality, and stillbirths. We also reviewed the cost-effectiveness of the women's group intervention and estimated its potential effect at scale in Countdown countries.
FINDINGS: Seven trials (119,428 births) met the inclusion criteria. Meta-analyses of all trials showed that exposure to women's groups was associated with a 37% reduction in maternal mortality (odds ratio 0.63, 95% CI 0.32-0.94), a 23% reduction in neonatal mortality (0.77, 0.65-0.90), and a 9% non-significant reduction in stillbirths (0.91, 0.79-1.03), with high heterogeneity for maternal (I(2)=58.8%, p=0.024) and neonatal results (I(2)=64.7%, p=0.009). In the meta-regression analyses, the proportion of pregnant women in groups was linearly associated with reduction in both maternal and neonatal mortality (p=0.026 and p=0.011, respectively). A subgroup analysis of the four studies in which at least 30% of pregnant women participated in groups showed a 55% reduction in maternal mortality (0.45, 0.17-0.73) and a 33% reduction in neonatal mortality (0.67, 0.59-0.74). The intervention was cost effective by WHO standards and could save an estimated 283,000 newborn infants and 41,100 mothers per year if implemented in rural areas of 74 Countdown countries.
INTERPRETATION: With the participation of at least a third of pregnant women and adequate population coverage, women's groups practising participatory learning and action are a cost-effective strategy to improve maternal and neonatal survival in low-resource settings.
