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.

Regional variability in facility-based delivery (FBD) rates in sub-Saharan Africa (SSA) is not well understood, nor is the relationship between FBD and national maternal and early neonatal mortality rates. A systematic literature review identified studies documenting the factors associated with FBD, stratified by region. Rates of skilled birth attendance, facility delivery, maternal mortality, and early neonatal mortality were compared across nations and regions. 70 articles met inclusion criteria, reflecting wide variability in the number, type, and quality of studies by region. Within-country differences were most pronounced in nations where multiple studies were conducted. Correlation between FBD and maternal mortality rates throughout SSA was -0.69 (p=.008), and the correlation between facility delivery rates and early neonatal mortality rates was -0.41 (p=0.08). This study demonstrates the need to attend to regional differences both across and within SSA nations if facility delivery rates are to be improved to reduce maternal and early neonatal mortality.
Financial barriers can affect timely access to maternal health services. Health insurance can influence the use and quality of these services and potentially improve maternal and neonatal health outcomes. We conducted a systematic review of the evidence on health insurance and its effects on the use and provision of maternal health services and on maternal and neonatal health outcomes in middle- and low-income countries. Studies were identified through a literature search in key databases and consultation with experts in healthcare financing and maternal health. Twenty-nine articles met the review criteria of focusing on health insurance and its effect on the use or quality of maternal health services, or maternal and neonatal health outcomes. Sixteen studies assessed demand-side effects of insurance, eight focused on supply-side effects, and the remainder addressed both. Geographically, the studies provided evidence from sub-Saharan Africa (n = 11), Asia (n = 9), Latin America (n = 8), and Turkey. The studies included examples from national or social insurance schemes (n = 7), government-run public health insurance schemes (n = 4), community-based health insurance schemes (n = 11), and private insurance (n = 3). Half of the studies used econometric analyses while the remaining provided descriptive statistics or qualitative results. There is relatively consistent evidence that health insurance is positively correlated with the use of maternal health services. Only four studies used methods that can establish this causal relationship. Six studies presented suggestive evidence of over-provision of caesarean sections in response to providers' payment incentives through health insurance. Few studies focused on the relationship between health insurance and the quality of maternal health services or maternal and neonatal health outcomes. The available evidence on the quality and health outcomes is inconclusive, given the differences in measurement, contradictory findings, and statistical limitations. Consistent with economic theories, the studies identified a positive relationship between health insurance and the use of maternal health services. However, more rigorous causal methods are needed to identify the extent to which the use of these services increases among the insured. Better measurement of quality and the use of cross-country analyses would solidify the evidence on the impact of insurance on the quality of maternal health services and maternal and neonatal health outcomes.
OBJECTIVES: Community-based health insurance (CBI) is a common mechanism to generate financial resources for health care in developing countries. We review for the first time provider payment methods used in CBI in developing countries and their impact on CBI performance.
METHODS: We conducted a systematic review of the literature on provider payment methods used by CBI in developing countries published up to January 2010.
RESULTS: Information on provider payment was available for a total of 32 CBI schemes in 34 reviewed publications: 17 schemes in South Asia, 10 in sub-Saharan Africa, 4 in East Asia and 1 in Latin America. Various types of provider payment were applied by the CBI schemes: 17 used fee-for-service, 12 used salaries, 9 applied a coverage ceiling, 7 used capitation and 6 applied a co-insurance. The evidence suggests that provider payment impacts CBI performance through provider participation and support for CBI, population enrolment and patient satisfaction with CBI, quantity and quality of services provided and provider and patient retention. Lack of provider participation in designing and choosing a CBI payment method can lead to reduced provider support for the scheme.
CONCLUSION: CBI schemes in developing countries have used a wide range of provider payment methods. The existing evidence suggests that payment methods are a key determinant of CBI performance and sustainability, but the strength of this evidence is limited since it is largely based on observational studies rather than on trials or on quasi-experimental research. According to the evidence, provider payment can affect provider participation, satisfaction and retention in CBI; the quantity and quality of services provided to CBI patients; patient demand of CBI services; and population enrollment, risk pooling and financial sustainability of CBI. CBI schemes should carefully consider how their current payment methods influence their performance, how changes in the methods could improve performance, and how such effects could be assessed with scientific rigour to increase the strength of evidence on this topic.
WHAT DO WE WANT TO KNOW AND WHY?: Moving away from out-of-pocket (OOP) payments for healthcare at the time of use to prepayment through health insurance (HI) is an important step towards averting financial hardships associated with paying for health services. Social health insurance (SHI) is mandated for those employed in many developed countries where employment and wage rates are high; this service is extended to those unemployed through subsidy. In low- and middle-income countries (LMICs) some version of SHI has been offered to those in the informal labour sector, who may well comprise the majority of the workforce. We carried out a systematic review of studies reporting on the impact of health insurance schemes that are intended to benefit the poor, mostly employed in the informal sector, in LMICs at a national level, or have the potential to be scaled up to be delivered to a large population.
WHO WANTS TO KNOW AND WHY?: Our findings will help policy makers to learn what lessons the implementation of such insurance suggests in terms of welfare enhancement to those who currently undertake out-of-pocket health expenditure, which often exacerbates their already meagre material living conditions. The information in this document will help reshape existing programmes, and assess the need for expanding and introducing HI programmes for the poor and those in the informal sector. We further aim to influence future effort in examining the impact of health insurance by detailing appropriate methods that have succeeded in identifying the impact of insurance, given the mechanism through which schemes were offered.
WHAT DID WE FIND?: Our systematic review showed inconclusive evidence. Low enrolment is commonly observed in many of the insurance schemes we examined. Many health system factors may play a role in explaining low enrolment; studies did not explore supply factors. We do not observe a pattern regarding enrolment and outcome: for example, high enrolment is not correlated with better outcomes. There is some evidence that health insurance may prevent high levels of expenditure. From those studies reporting on whether or not the impact on the subgroup of insured that were poorer was more noticeable, we find that the impact was smaller for the poorer population. That is, the insured poor may be undertaking higher OOP expenditure than those who are not insured.
WHAT ARE THE IMPLICATIONS?: Greater effort needs to be undertaken to study the health-seeking behaviour of those insured and those uninsured in LMICs.
HOW DID WE GET THESE RESULTS?: We give results from 34 studies that report the impact of health insurance for the poor using quantitative methods. We found no qualitative studies. We emphasise the results from those studies that made a significant effort to use statistical methods currently prevalent in the economics literature on impact evaluation.

BACKGROUND: Delays in receiving effective care during labor and at birth may be fatal for the mother and fetus, contributing to 2 million annual intrapartum stillbirths and intrapartum-related neonatal deaths each year.
OBJECTIVE: We present a systematic review of strategies to link families and facilities, including community mobilization, financial incentives, emergency referral and transport systems, prenatal risk screening, and maternity waiting homes.
RESULTS: There is moderate quality evidence that community mobilization with high levels of community engagement can increase institutional births and significantly reduce perinatal and early neonatal mortality. Meta-analysis showed a doubling of skilled birth attendance and a 36% reduction in early neonatal mortality. However, no data are available on intrapartum-specific outcomes. Evidence is limited, but promising, that financial incentive schemes and community referral/transport systems may increase rates of skilled birth attendance and emergency obstetric care utilization; however, impact on mortality is unknown. Current evidence for maternity waiting homes and risk screening is low quality.
CONCLUSIONS: Empowering communities is an important strategy to reduce the large burden of intrapartum complications. Innovations are needed to bring the poor closer to obstetric care, such as financial incentives and cell phone technology. New questions need to be asked of "old" strategies such as risk screening and maternity waiting homes. The effect of all of these strategies on maternal and perinatal mortality, particularly intrapartum-related outcomes, requires further evaluation.
