A systematic mapping of funders of maternal health intervention research 2000-2012

BACKGROUND

The priorities of research funding bodies govern the research agenda, which has important implications for the provision of evidence to inform policy. This study examines the research funding landscape for maternal health interventions in low- and middle-income countries (LMICs).

METHODS

This review draws on a database of 2340 academic papers collected through a large-scale systematic mapping of research on maternal health interventions in LMICs published from 2000-2012. The names of funders acknowledged on each paper were extracted and categorised into groups. It was noted whether support took a specific form, such as staff fellowships or drugs. Variations between funder types across regions and topics of research were assessed.

RESULTS

Funding sources were only reported in 1572 (67%) of articles reviewed. A high number of different funders (685) were acknowledged, but only a few dominated funding of published research. Bilateral funders, national research agencies and private foundations were most prominent, while private companies were most commonly acknowledged for support 'in kind'. The intervention topics and geographic regions of research funded by the various funder types had much in common, with HIV being the most common topic and sub-Saharan Africa being the most common region for all types of funder. Publication outputs rose substantially for several funder types over the period, with the largest increase among bilateral funders.

CONCLUSIONS

A considerable number of organisations provide funding for maternal health research, but a handful account for most funding acknowledgements. Broadly speaking, these organisations address similar topics and regions. This suggests little coordination between funding agencies, risking duplication and neglect of some areas of maternal health research, and limiting the ability of organisations to develop the specialised skills required for systematically addressing a research topic. Greater transparency in reporting of funding is required, as the role of funders in the research process is often unclear.

Insights in public health: The Special Supplemental Nutrition Program for Women, Infants and Children: strengthening families for 40 years

The Special Supplemental Nutrition Program for Women, Infants and Children (WIC) is a proven, cost-effective investment in strengthening families. As part of the United States Department of Agriculture's (USDA) 15 federal nutrition assistance programs for the past 40 years, WIC has grown to be the nation's leading public health nutrition program. WIC serves as an important first access point to health care and social service systems for many limited resource families, serving approximately half the births in the nation as well as locally. By providing nutrition education, breastfeeding promotion and foods in addition to referrals, WIC plays a crucial role in promoting lifetime health for women, infants and children. WIC helps achieve national public health goals such as reducing premature births and infant mortality, increasing breastfeeding, and reducing maternal and childhood overweight. Though individuals and families can self-refer into WIC, physicians and allied health professionals have the opportunity and are encouraged to promote awareness of WIC and refer families in their care.

Child care subsidies, maternal health, and child-parent interactions: evidence from three nationally representative datasets

A complete account of the US child care subsidy system requires an understanding of its implications for both parental and child well-being. Although the effects of child care subsidies on maternal employment and child development have been recently studied, many other dimensions of family well-being have received little attention. This paper attempts to fill this gap by examining the impact of child care subsidy receipt on maternal health and the quality of child-parent interactions. The empirical analyses use data from three nationally representative surveys, providing access to numerous measures of family well-being. In addition, we attempt to handle the possibility of non-random selection into subsidy receipt by using several identification strategies both within and across the surveys. Our results consistently indicate that child care subsidies are associated with worse maternal health and poorer interactions between parents and their children. In particular, subsidized mothers report lower levels of overall health and are more likely to show symptoms consistent with anxiety, depression, and parenting stress. Such mothers also reveal more psychological and physical aggression toward their children and are more likely to utilize spanking as a disciplinary tool. Together, these findings suggest that work-based public policies aimed at economically disadvantaged mothers may ultimately undermine family well-being.

Parental health and child schooling

This paper provides new empirical evidence on the impact of parental health shocks on investments in children's education using detailed longitudinal data from Bosnia and Herzegovina. Our study controls for individual unobserved heterogeneity by using child fixed effects, and it accounts for potential misreporting of self-reported health by employing several, more precise, health indicators. Results show that co-living children of ill mothers, but not of ill fathers, are significantly less likely to be enrolled in education at ages 15-24. Moreover, there is some evidence that mother's negative health shocks are likely to raise the employment probability of children due to the need to cover higher health expenditures.

Study protocol for a randomized, controlled, superiority trial comparing the clinical and cost- effectiveness of integrated online mental health assessment-referral-care in pregnancy to usual prenatal care on prenatal and postnatal mental health and infant health and development: the Integrated Maternal Psychosocial Assessment to Care Trial (IMPACT)

BACKGROUND

Stress, depression, and anxiety affect 15 to 25% of pregnant women. However, fewer than 20% of prenatal care providers assess and treat mental health problems and fewer than 20% of pregnant women seek mental healthcare. For those who seek treatment, the lack of health system integration and existing barriers frequently prevent treatment access. Without treatment, poor prenatal mental health can persist for years and impact future maternal, child, and family well-being.

METHODS/DESIGN

The purpose of this randomized controlled trial is to evaluate the effectiveness of an integrated process of online psychosocial assessment, referral, and cognitive behavior therapy (CBT) for pregnant women compared to usual prenatal care (no formal screening or specialized care). The primary outcome is self-reported prenatal depression, anxiety, and stress symptoms at 6 to 8 weeks postrandomization. Secondary outcomes are postpartum depression, anxiety, and stress symptoms; self-efficacy; mastery; self-esteem; sleep; relationship quality; coping; resilience; Apgar score; gestational age; birth weight; maternal-infant attachment; infant behavior and development; parenting stress/competence; and intervention cost-effectiveness, efficiency, feasibility, and acceptability. Pregnant women are eligible if they: 1) are <28 weeks gestation; 2) speak/read English; 3) are willing to complete email questionnaires; 4) have no, low, or moderate psychosocial risk on screening at recruitment; and 5) are eligible for CBT. A sample of 816 women will be recruited from large, urban primary care clinics and allocation is by computer-generated randomization. Women in the intervention group will complete an online psychosocial assessment, and those with mild or moderate depression, anxiety, or stress symptoms then complete six interactive cognitive behavior therapy modules. All women will complete email questionnaires at 6 to 8 weeks postrandomization and at 3, 6, and 12 months postpartum. Clinic-based providers and researchers conducting chart abstraction and analysis are blinded. Qualitative interviews with 8 to 10 healthcare providers and 15 to 30 intervention group women will provide data on feasibility and acceptability of the intervention. Results of this trial will determine the feasibility and effectiveness of an integrated approach to prenatal mental healthcare and the use of highly accessible computer-based psychosocial assessment and CBT on maternal, infant, and family-based outcomes.

Performance-based incentives to improve health status of mothers and newborns: what does the evidence show?

Performance-based incentives (PBIs) aim to counteract weak providers' performance in health systems of many developing countries by providing rewards that are directly linked to better health outcomes for mothers and their newborns. Translating funding into better health requires many actions by a large number of people. The actions span from community to the national level. While different forms of PBIs are being implemented in a number of countries to improve health outcomes, there has not been a systematic review of the evidence of their impact on the health of mothers and newborns. This paper analyzes and synthesizes the available evidence from published studies on the impact of supply-side PBIs on the quantity and quality of health services for mothers and newborns. This paper reviews evidence from published and grey literature that spans PBI for public-sector facilities, PBI in social insurance reforms, and PBI in NGO contracting. Some initiatives focus on safe deliveries, and others reward a broader package of results that include deliveries. The Evidence Review Team that focused on supply-side incentives for the US Government Evidence Summit on Enhancing Provision and Use of Maternal Health Services through Financial Incentives, reviewed published research reports and papers and added studies from additional grey literature that were deemed relevant. After collecting and reviewing 17 documents, nine studies were included in this review, three of which used before-after designs; four included comparison or control groups; one applied econometric methods to a five-year time series; and one reported results from a large-scale impact evaluation with randomly-assigned intervention and control facilities. The available evidence suggests that incentives that reward providers for institutional deliveries result in an increase in the number of institutional deliveries. There is some evidence that the content of antenatal care can improve with PBI. We found no direct evidence on the impact of PBI on neonatal health services or on mortality of mothers and newborns, although intention of the study was not to document impact on mortality. A number of studies describe approaches to rewarding quality as well as increases in the quantities of services provided, although how quality is defined and monitored is not always clear. Because incentives exist in all health systems, considering how to align the incentives of the many health workers and their supervisors so that they focus efforts on achieving health goals for mothers and newborns is critical if the health system is to perform more effectively and efficiently. A wide range of PBI models is being developed and tested, and there is still much to learn about what works best. Future studies should include a larger focus on rewarding quality and measuring its impact. Finally, more qualitative research to better understand PBI implementation and how various incentive models function in different settings is needed to help practitioners refine and improve their programmes.

Effect of health insurance on the use and provision of maternal health services and maternal and neonatal health outcomes: a systematic review

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.

Investigating financial incentives for maternal health: an introduction

Projection of current trends in maternal and neonatal mortality reduction shows that many countries will fall short of the UN Millennium Development Goal 4 and 5. Underutilization of maternal health services contributes to this poor progress toward reducing maternal and neonatal morbidity and mortality. Moreover, the quality of services continues to lag in many countries, with a negative effect on the health of women and their babies, including deterring women from seeking care. To enhance the use and provision of quality maternal care, countries and donors are increasingly using financial incentives. This paper introduces the JHPN Supplement, in which each paper reviews the evidence of the effectiveness of a specific financial incentive instrument with the aim of improving the use and quality of maternal healthcare and impact. The US Agency for International Development and the US National Institutes of Health convened a US Government Evidence Summit on Enhancing Provision and Use of Maternal Health Services through Financial Incentives on 24-25 April 2012 in Washington, DC. The Summit brought together leading global experts in finance, maternal health, and health systems from governments, academia, development organizations, and foundations to assess the evidence on whether financial incentives significantly and substantially increase provision, use and quality of maternal health services, and the contextual factors that impact the effectiveness of these incentives. Evidence review teams evaluated the multidisciplinary evidence of various financial mechanisms, including supply-side incentives (e.g. performance-based financing, user fees, and various insurance mechanisms) and demand-side incentives (e.g. conditional cash transfers, vouchers, user fee exemptions, and subsidies for care-seeking). At the Summit, the teams presented a synthesis of evidence and initial recommendations on practice, policy, and research for discussion. The Summit enabled structured feedback on recommendations which the teams included in their final papers appearing in this Supplement. Papers in this Supplement review the evidence for a specific financial incentive mechanism (e.g. pay for performance, conditional cash transfer) to improve the use and quality of maternal healthcare and makes recommendations for programmes and future research. While data on programmes using financial incentives for improved use and indications of the quality of maternal health services support specific conclusions and recommendations, including those for future research, data linking the use of financial incentives with improved health outcomes are minimal.

Impact of conditional cash transfers on maternal and newborn health

Maternal and newborn health (MNH) is a high priority for global health and is included among the Millennium Development Goals (MDGs). However, the slow decline in maternal and newborn mortality jeopardizes achievements of the targets of MDGs. According to UNICEF, 60 million women give birth outside of health facilities, and family planning needs are satisfied for only 50%. Further, skilled birth attendance and the use of antenatal care are most inequitably distributed in maternal and newborn health interventions in low- and middle-income countries. Conditional cash transfer (CCT) programmes have been shown to increase health service utilization among the poorest but little is written on the effects of such programmes on maternal and newborn health. We carried out a systematic review of studies on CCT that report maternal and newborn health outcomes, including studies from 8 countries. The CCT programmes have increased antenatal visits, skilled attendance at birth, delivery at a health facility, and tetanus toxoid vaccination for mothers and reduced the incidence of low birthweight. The programmes have not had a significant impact on fertility while the impact on maternal and newborn mortality has not been well-documented thus far. Given these positive effects, we make the case for further investment in CCT programmes for maternal and newborn health, noting gaps in knowledge and providing recommendations for better design and evaluation of such programmes. We recommend more rigorous impact evaluations that document impact pathways and take factors, such as cost-effectiveness, into account.

Financial incentives and maternal health: where do we go from here?

Health financing strategies that incorporate financial incentives are being applied in many low- and middle-income countries, and improving maternal and neonatal health is often a central goal. As yet, there have been few reviews of such programmes and their impact on maternal health. The US Government Evidence Summit on Enhancing Provision and use of Maternal Health Services through Financial Incentives was convened on 24-25 April 2012 to address this gap. This article, the final in a series assessing the effects of financial incentives--performance-based incentives (PBIs), insurance, user fee exemption programmes, conditional cash transfers, and vouchers--summarizes the evidence and discusses issues of context, programme design and implementation, cost-effectiveness, and sustainability. We suggest key areas to consider when designing and implementing financial incentive programmes for enhancing maternal health and highlight gaps in evidence that could benefit from additional research. Although the methodological rigor of studies varies, the evidence, overall, suggests that financial incentives can enhance demand for and improve the supply of maternal health services. Definitive evidence demonstrating a link between incentives and improved health outcomes is lacking; however, the evidence suggests that financial incentives can increase the quantity and quality of maternal health services and address health systems and financial barriers that prevent women from accessing and providers from delivering quality, lifesaving maternal healthcare.

A taxonomy and results from a comprehensive review of 28 maternal health voucher programmes

It is increasingly clear that Millennium Development Goal 4 and 5 will not be achieved in many low- and middle-income countries with the weakest gains among the poor. Recognizing that there are large inequalities in reproductive health outcomes, the post-2015 agenda on universal health coverage will likely generate strategies that target resources where maternal and newborn deaths are the highest. In 2012, the United States Agency for International Development convened an Evidence Summit to review the knowledge and gaps on the utilization of financial incentives to enhance the quality and uptake of maternal healthcare. The goal was to provide donors and governments of the low- and middle-income countries with evidence-informed recommendations on practice, policy, and strategies regarding the use of financial incentives, including vouchers, to enhance the demand and supply of maternal health services. The findings in this paper are intended to guide governments interested in maternal health voucher programmes with recommendations for sustainable implementation and impact. The Evidence Summit undertook a systematic review of five financing strategies. This paper presents the methods and findings for vouchers, building on a taxonomy to catalogue knowledge about voucher programme design and functionality. More than 120 characteristics under five major categories were identified: programme principles (objectives and financing); governance and management; benefits package and beneficiary targeting; providers (contracting and service pricing); and implementation arrangements (marketing, claims processing, and monitoring and evaluation). Among the 28 identified maternal health voucher programmes, common characteristics included: a stated objective to increase the use of services among the means-tested poor; contracted-out programme management; contracting either exclusively private facilities or a mix of public and private providers; prioritizing community-based distribution of vouchers; and tracking individual claims for performance purposes. Maternal voucher programmes differed on whether contracted providers were given training on clinical or administrative issues; whether some form of service verification was undertaken at facility or community-level; and the relative size of programme management costs in the overall programme budget. Evidence suggests voucher programmes can serve populations with national-level impact. Reaching scale depends on whether the voucher programme can: (i) keep management costs low, (ii) induce a large demand-side response among the bottom two quintiles, and (iii) achieve a quality of care that translates a greater number of facility-based deliveries into a reduction in maternal morbidity and mortality.

Effects of user fee exemptions on the provision and use of maternal health services: a review of literature

User fee removal has been put forward as an approach to increasing priority health service utilization, reducing impoverishment, and ultimately reducing maternal and neonatal mortality. However, user fees are a source of facility revenue in many low-income countries, often used for purchasing drugs and supplies and paying incentives to health workers. This paper reviews evidence on the effects of user fee exemptions on maternal health service utilization, service provision, and outcomes, including both supply-side and demand-side effects. We reviewed 19 peer-reviewed research articles addressing user fee exemptions and maternal health services or outcomes published since 1990. Studies were identified through a USAID-commissioned call for evidence, key word search, and screening process. Teams of reviewers assigned criteria-based quality scores to each paper and prepared structured narrative reviews. The grade of the evidence was found to be relatively weak, mainly from short-term, non-controlled studies. The introduction of user fee exemptions appears to have resulted in increased rates of facility-based deliveries and caesarean sections in some contexts. Impacts on maternal and neonatal mortality have not been conclusively demonstrated; exemptions for delivery care may contribute to modest reductions in institutional maternal mortality but the evidence is very weak. User fee exemptions were found to have negative, neutral, or inconclusive effects on availability of inputs, provider motivation, and quality of services. The extent to which user fee revenue lost by facilities is replaced can directly affect service provision and may have unintended consequences for provider motivation. Few studies have looked at the equity effects of fee removal, despite clear evidence that fees disproportionately burden the poor. This review highlights potential and documented benefits (increased use of maternity services) as well as risks (decreased provider motivation and quality) of user fee exemption policies for maternal health services. Governments should link user fee exemption policies with the replacement of lost revenue for facilities as well as broader health system improvements, including facility upgrades, ensured supply of needed inputs, and improved human resources for health. Removing user fees may increase uptake but will not reduce mortality proportionally if the quality of facility-based care is poor. More rigorous evaluations of both demand- and supply-side effects of mature fee exemption programmes are needed.

Evidence acquisition and evaluation for evidence summit on enhancing provision and use of maternal health services through financial incentives

Recognizing the need for evidence to inform US Government and governments of the low- and middle-income countries on efficient, effective maternal health policies, strategies, and programmes, the US Government convened the Evidence Summit on Enhancing Provision and Use of Maternal Health Services through Financial Incentives in April 2012 in Washington, DC, USA. This paper summarizes the background and methods for the acquisition and evaluation of the evidence used for achieving the goals of the Summit. The goal of the Summit was to obtain multidisciplinary expert review of literature to inform both US Government and governments of the low- and middle-income countries on evidence-informed practice, policies, and strategies for financial incentives. Several steps were undertaken to define the tasks for the Summit and identify the appropriate evidence for review. The process began by identifying focal questions intended to inform governments of the low-and middle-income countries and the US Government about the efficacy of supply- and demand-side financial incentives for enhanced provision and use of quality maternal health services. Experts were selected representing the research and programme communities, academia, relevant non-governmental organizations, and government agencies and were assembled into Evidence Review Teams. This was followed by a systematic process to gather relevant peer-reviewed literature that would inform the focal questions. Members of the Evidence Review Teams were invited to add relevant papers not identified in the initial literature review to complete the bibliography. The Evidence Review Teams were asked to comply with a specific evaluation framework for recommendations on practice and policy based on both expert opinion and the quality of the data. Details of the search processes and methods used for screening and quality reviews are described.

Estimating the cost-savings associated with bundling maternal and child health interventions: a proposed methodology

BACKGROUND

There is a pressing need to include cost data in the Lives Saved Tool (LiST). This paper proposes a method that combines data from both the WHO CHOosing Interventions that are Cost-Effective (CHOICE) database and the OneHealth Tool (OHT) to develop unit costs for delivering child and maternal health services, both alone and bundled.

METHODS

First, a translog cost function is estimated to calculate factor shares of personnel, consumables, other direct (variable or recurrent costs excluding personnel and consumables) and indirect (capital or investment) costs. Primary source facility level data from Kenya, Namibia, South Africa, Uganda, Zambia and Zimbabwe are utilized, with separate analyses for hospitals and health centres. Second, the resulting other-direct and indirect factor shares are applied to country unit costs from the WHO CHOICE unit cost database to calculate those portions of unit cost. Third, the remainder of the costs is calculated using default data from the OHT. Fourth, we calculate the effect of bundling services by assuming that a LiST intervention visit takes an average of 20 minutes when delivered alone but only incremental time in addition to the basic visit when delivered in a bundle.

RESULTS

Personnel costs account for the greatest share of costs for both hospitals and health centres at 50% and 38%, respectively. The percentages differ between hospitals and health centres for consumables (21% versus 17%), other direct (7.5% versus 6.75%), and indirect (22% versus 23%) costs. Combining the other-direct and indirect factor shares with the WHO CHOICE database and the other costs from OHT provides a comprehensive cost estimate of LiST interventions. Finally, the cost of six recommended antenatal care (ANC) interventions is $69.76 when delivered alone, but $61.18 when delivered as a bundle, a savings of $8.58 (12.2%).

CONCLUSIONS

This paper proposes a method for estimating a comprehensive cost of providing child and maternal health interventions by combining labor, consumables and drug costs from OHT with indirect and other-direct proportional costs from WHO CHOICE. In addition, we demonstrate the potential cost savings that can be achieved from bundling the delivery of essential antenatal care interventions rather than delivering the same interventions alone.

Targeted interventions for improved equity in maternal and child health in low- and middle-income settings: a systematic review and meta-analysis

BACKGROUND

Targeted interventions to improve maternal and child health is suggested as a feasible and sometimes even necessary strategy to reduce inequity. The objective of this systematic review was to gather the evidence of the effectiveness of targeted interventions to improve equity in MDG 4 and 5 outcomes.

METHODS AND FINDINGS

We identified primary studies in all languages by searching nine health and social databases, including grey literature and dissertations. Studies evaluating the effect of an intervention tailored to address a structural determinant of inequity in maternal and child health were included. Thus general interventions targeting disadvantaged populations were excluded. Outcome measures were limited to indicators proposed for Millennium Development Goals 4 and 5. We identified 18 articles, whereof 15 evaluated various incentive programs, two evaluated a targeted policy intervention, and only one study evaluated an intervention addressing a cultural custom. Meta-analyses of the effectiveness of incentives programs showed a pooled effect size of RR 1.66 (95% CI 1.43-1.93) for antenatal care attendance (four studies with 2,476 participants) and RR 2.37 (95% CI 1.38-4.07) for health facility delivery (five studies with 25,625 participants). Meta-analyses were not performed for any of the other outcomes due to scarcity of studies.

CONCLUSIONS

The targeted interventions aiming to improve maternal and child health are mainly limited to addressing economic disparities through various incentive schemes like conditional cash transfers and voucher schemes. This is a feasible strategy to reduce inequity based on income. More innovative action-oriented research is needed to speed up progress in maternal and child survival among the most disadvantaged populations through interventions targeting the underlying structural determinants of inequity.

Reducing maternal mortality in Nigeria: the need for urgent changes in financing for maternal health in the Nigerian health system

AIMS AND OBJECTIVES

Nigeria's maternal mortality indices are among the worst in the world. Various approaches aimed at combatting the persistently high maternal mortality rates in the past have been ineffective. The objective of this article was to evaluate the fairness and equitability of financing for maternal health in the Nigerian health system.

METHODS

A review of the performance of the Nigerian Health system with regards to financing for maternal healthcare and comparison with other health systems utilising internationally accepted criteria was done.

RESULTS

Household out-of -pocket payment was found to be the largest source of health care financing in the Nigerian health system contributing as much as 65.6 % of total health expenditure. This is in sharp contrast to the performance of more effective health systems like that in South Africa where health care is free for pregnant and breast feeding mothers. The result is that South Africa reports less than a tenth of total maternal mortalities reported from Nigeria annually. The current Nigeria health financing system is not equitable and appears to encourage maternal mortalities since it does not cater for the most vulnerable.

CONCLUSION

There is an urgent need for a review of financing of maternal health in Nigeria to achieve universal access to maternal health care. An urgent overhaul of the currently under performing National Health Insurance scheme or adoption of the simpler system based on funding from taxation with universal access for health care including maternal care and services free at the point of access is suggested.

Productivity cost due to maternal ill health in Sri Lanka

BACKGROUND

The global impact of maternal ill health on economic productivity is estimated to be over 15 billion USD per year. Global data on productivity cost associated with maternal ill health are limited to estimations based on secondary data. Purpose of our study was to determine the productivity cost due to maternal ill health during pregnancy in Sri Lanka.

METHODS AND FINDINGS

We studied 466 pregnant women, aged 24 to 36 weeks, residing in Anuradhapura, Sri Lanka. A two stage cluster sampling procedure was used in a cross sectional design and all pregnant women were interviewed at clinic centers, using the culturally adapted Immpact tool kit for productivity cost assessment. Of the 466 pregnant women studied, 421 (90.3%) reported at least one ill health condition during the pregnancy period, and 353 (83.8%) of them had conditions affecting their daily life. Total incapacitation requiring another person to carry out all their routine activities was reported by 122 (26.1%) of the women. In this study sample, during the last episode of ill health, total number of days lost due to absenteeism was 3,356 (32.9% of total loss) and the days lost due to presenteeism was 6,832.8 (67.1% of the total loss). Of the 353 women with ill health conditions affecting their daily life, 280 (60%) had coping strategies to recover loss of productivity. Of the coping strategies used to recover productivity loss during maternal ill health, 76.8% (n = 215) was an intra-household adaptation, and 22.8% (n = 64) was through social networks. Loss of productivity was 28.9 days per episode of maternal ill health. The mean productivity cost due to last episode of ill health in this sample was Rs.8,444.26 (95% CI-Rs.6888.74-Rs.9999.78).

CONCLUSIONS

Maternal ill health has a major impact on household productivity and economy. The major impact is due to, generally ignored minor ailments during pregnancy.

Economic consequences of maternal illness in rural Bangladesh

We use panel data on household consumption combined with information taken from the medical records of women who gave birth in health facilities to explore the economic consequences of maternal ill health, in the context of a rural population in Bangladesh. The findings suggest that there is a large reduction in household resources associated with maternal illness, driven almost entirely by spending on health care. In spite of this loss of resources, we find that households are able to fully insure consumption against maternal ill health, although confidence intervals are unable to rule out a small effect. Households in our study area are shown to have good access to informal credit (whether it be from local money lenders or family relatives), and this appears critical in helping to smooth consumption in response to these health shocks, at least in the short term.

Effects of growth environments and two environmental endocrine disruptors on children with idiopathic precocious puberty

OBJECTIVE

The incidence of idiopathic precocious puberty (IPP) might have an increasing trend. But the causes and risk factors of IPP are unknown. The objective of our study is to evaluate the effects of growth environments and two environmental endocrine disruptors (EDCs), zearalenone (ZEA), and 1,1-dichloro-2,2,bisethylene (p,p'-DDE), on patients with IPP.

DESIGN

Case-control study.

METHODS

The study consisted of 78 IPP patients at diagnosis and 100 control children matched for age and sex. A questionnaire was designed to collect data on growth environments, and serum ZEA and p,p'-DDE were tested in all subjects. We analyzed data on growth environments, two EDCs, and biological interaction between growth environments and EDCs.

RESULTS

In growth environments, small for gestational age, maternal physical disease during pregnancy, early maternal menarche, early puberty of same-degree relatives, and father's absence in 4- to 6-year olds were risk factors for children with IPP (P<0.05). Serum ZEA concentration, ZEA, and p,p'-DDE-positive rates in the IPP group were significantly higher than those in the control group (P<0.05). There was a biological interaction between growth environments and ZEA (relative excess risk due to interaction =34.562, attributable proportion due to interaction =0.745, synergy index =4.193).

CONCLUSIONS

Results suggest possible effects of growth environments and two EDCs on the development of IPP. In addition, growth environments and ZEA have biological interaction that might increase the risk of developing IPP.

Financial incentives for maternal health: impact of a national programme in Nepal

Financial incentives are increasingly being advocated as an effective means to influence health-related behaviours. There is, however, limited evidence on whether they work in low-income countries, particularly when implemented at scale. This paper explores the impact of a national programme in Nepal that provides cash incentives to women conditional on them giving birth in a health facility. Using propensity score matching methods, we find that the programme had a positive, albeit modest, effect on the utilisation of maternity services. Women who had heard of the SDIP before childbirth were 4.2 percentage points (17 percent) more likely to deliver with a skilled attendant. The treatment effect is positively associated with the size of the financial package offered by the programme and the quality of care in facilities. Despite the positive effect on those exposed to the SDIP, low coverage of the programme suggests that few women actually benefited in the first few years.

Evaluation of the impact of the Mother and Infant Health Project in Ukraine

This paper exploits a unique opportunity to evaluate the impact of the quality change in the labor and delivery services brought about by the Mother and Infant Health Project in Ukraine. Employing program evaluation methods, we find that the administrative units participating in the Project have exhibited greater improvements in both maternal and infant health compared to the control ones. Among the infant health characteristics, the MIHP impact is most pronounced for infant mortality resulting from deviations in perinatal period. As for the maternal health, the MIHP is the most effective at combating anemia, blood circulation and urinary-genital system complications, and late toxicosis. The analysis suggests that the effects are due to early attendance of antenatal clinics, lower share of C-sections, and greater share of normal deliveries. Preliminary cost-effectiveness analysis shows enormous benefit per dollar spent on the project: the cost to benefit ratio is one to 97 taking into account both maternal and infant lives saved as well as cost savings due to the changes in labor and delivery practices.

Mexico's conditional cash transfer programme increases cesarean section rates among the rural poor

BACKGROUND

Caesarean section rates are increasing in Mexico and Latin America. This study evaluates the impact of a large-scale, conditional cash transfer programme in Mexico on caesarean section rates. The programme provides cash transfers to participating low income, rural households in Mexico conditional on accepting health care and nutrition supplements.

METHODS

The primary analyses uses retrospective reports from 979 women in poor rural communities participating in an effectiveness study and randomly assigned to incorporation into the programme in 1998 or 1999 across seven Mexican states. Using multivariate and instrumental variable analyses, we estimate the impact of the programme on caesarean sections and predict the adjusted mean rates by clinical setting. Programme participation is measured by beneficiary status, programme months and cash transfers.

RESULTS

More than two-thirds of poor rural women delivered in a health facility. Beneficiary status is associated with a 5.1 percentage point increase in caesarean rates; this impact increases to 7.5 percentage points for beneficiaries enrolled in the programme for >or=6 months before delivery. Beneficiaries had significantly higher caesarean delivery rates in social security facilities (24.0 compared with 5.6% among non-beneficiaries) and in other government facilities (19.3 compared with 9.5%).

CONCLUSION

The Oportunidades conditional cash transfer programme is associated with higher caesarean section rates in social security and government health facilities. This effect appears to be driven by the increases in disposable income from the cash transfer. These findings are relevant to other countries implementing conditional cash transfer programmes and health care requirements.

Willingness to pay for maternal health outcomes: are women willing to pay more than men?

BACKGROUND

Only a limited number of studies have specifically sought to analyse and try to understand sex differences in willingness to pay (WTP).

OBJECTIVE

To identify the role of sex in determining monetary values placed upon improvements in maternal health in Burkina Faso, West Africa.

METHODS

A contingent valuation survey using the bidding game method was conducted in the district of Nouna in 2005; a sample of 409 male heads of households and their spouses were asked their WTP for a reduction in the number of maternal deaths in the Nouna area. Ordinary least squares regression analysis was employed to examine the determinants of WTP.

RESULTS

Men were willing to pay significantly more than women (3127 vs 2273 West African francs), although this represented a significantly smaller proportion of their annual income (4% vs 11%). In the multivariate analyses of all respondents there was a significant positive relationship between WTP values and both starting bid and whether there had been a previous maternal complication in the respondent's household. However, there was a significant negative relationship between WTP and female sex. Once interactions between sex and income were taken into account, income did affect valuations, with a positive relationship between higher-income women and WTP values.

CONCLUSION

In absolute terms, men were willing to pay more than women, while women were willing to pay a greater proportion of their income. Differences between men and women in their WTP, both in absolute terms and in terms of proportion of income, can be explained by a household effect. Future studies should distinguish between individual income and command over decision making with respect to use of individual and household income, and gain further insight into the strategies used by respondents in answering bidding game questions.

Compact ultrasound for improving maternal and perinatal care in low-resource settings: review of the potential benefits, implementation challenges, and public health issues

OBJECTIVE

Ultrasound imaging, a front-line diagnostic tool for perinatal care, is rarely available in the developing world, where maternal and newborn mortality rates are starkly higher than elsewhere. The development of portable and inexpensive medical ultrasound machines (compact ultrasound) offers the possibility of broader use of ultrasound. Our objective was to assess the potential benefits and challenges of deploying compact ultrasound in developing countries for improving obstetric health.

METHODS

Existing literature on perinatal care, compact ultrasound, and issues in the deployments of medical technology in low-resource settings was reviewed. Anecdotal evidence was assessed, and the authors' field experiences in Nicaragua and Mali were evaluated as a template for wider deployments.

RESULTS

Few published studies directly concerned with compact ultrasound in low-resource settings were found. These, however, in combination with available anecdotal data, support the view that compact ultrasound in less-developed regions is feasible and would result in a relatively low-cost improvement in perinatal care.

CONCLUSIONS

The development of lightweight, portable, and relatively inexpensive ultrasound systems offers a great opportunity for reducing maternal and neonatal mortality in low-resource settings. Evidence-based analysis of compact ultrasound deployments as a public-health response to obstetric needs in less-developed countries has been hampered by limited data in 3 key areas: maternal and perinatal mortality and morbidity in these settings, evaluations of compact ultrasound systems as reliable alternatives to full-sized systems, and the lack of outcomes data based on actual deployments of compact ultrasound for this purpose. Field trials of compact ultrasound on a scale commensurate with public health interventions should be undertaken.

Maternal obesity: a review of interventions

BACKGROUND

Obesity has become a serious global public health issue and has consequences for nearly all areas of medicine. Within obstetrics, obesity not only has direct implications for the health of a pregnancy but also impacts on the weight of the child in infancy and beyond. As such, maternal weight may influence the prevalence and severity of obesity in future generations. Pregnancy has been identified as a key time to target a weight control or weight loss strategy to help curb the rapidly growing obesity epidemic. In addition, if delivered sensitively, pregnancy may be a good time to target health behaviour changes by using the extra motivation women tend to have at this time to maximise the health of their child.

AIM

This study reviews the current evidence for interventions to promote weight control or weight loss in women around the time of pregnancy. A comprehensive review of medical research--PubMed, Embase, Ovid Medline and the Cochrane Clinical Trials register--showed that despite numerous reports of the prevalence and complications of maternal obesity, few intervention strategies have been suggested.

CONCLUSION

This study finds that there is a deficiency of appropriately designed interventions for maternal obesity and it concludes by highlighting areas for developing a more effective strategy.

Public funding for community-based skilled delivery care in Indonesia: to what extent are the poor benefiting?

Since the early 1990s, the Government of Indonesia has addressed high maternal mortality by attempting to ensure skilled attendance at delivery through access to trained village midwifery services in every village. Yet access to skilled services at delivery continues to prove problematic, with low levels of skilled attendance and high mortality. Making use of a funding flow analysis and population-based survey in two districts, we investigate to what extent funding allocated for maternal services enables access to skilled services by rich and poor households. The results suggest that, although resources reach remote poor areas, the poor obtain unequal access to skilled delivery services. Because rural midwives must earn a significant fraction of their income from private fees this acts to deter women from seeking their help. A new system of targeting poor women utilising the existing state insurance company (ASKES) is an important step in helping to reduce these barriers, but may not be sufficiently generous to protect all those that are considered vulnerable.

Urban women's socioeconomic status, health service needs and utilization in the four weeks after postpartum hospital discharge: findings of a Canadian cross-sectional survey

BACKGROUND

Postpartum women who experience socioeconomic disadvantage are at higher risk for poor health outcomes than more advantaged postpartum women, and may benefit from access to community based postpartum health services. This study examined socioeconomically disadvantaged (SED) postpartum women's health, and health service needs and utilization patterns in the first four weeks post hospital discharge, and compared them to more socioeconomically advantaged (SEA) postpartum women's health, health service needs and utilization patterns.

METHODS

Data collected as part of a large Ontario cross-sectional mother-infant survey were analyzed. Women (N = 1000) who had uncomplicated vaginal births of single 'at-term' infants at four hospitals in two large southern Ontario, Canada cities were stratified into SED and SEA groups based on income, social support and a universally administered hospital postpartum risk screen. Participants completed a self-administered questionnaire before hospital discharge and a telephone interview four weeks after discharge. Main outcome measures were self-reported health status, symptoms of postpartum depression, postpartum service needs and health service use.

RESULTS

When compared to the SEA women, the SED women were more likely to be discharged from hospital within the first 24 hours after giving birth [OR 1.49, 95% CI (1.01-2.18)], less likely to report very good or excellent health [OR 0.48, 95% CI (0.35-0.67)], and had higher rates of symptoms of postpartum depression [OR 2.7, 95% CI(1.64-4.4)]. No differences were found between groups in relation to self reported need for and ability to access services for physical and mental health needs, or in use of physicians, walk-in clinics and emergency departments. The SED group were more likely to accept public health nurse home visits [OR 2.24, 95% CI(1.47-3.40)].

CONCLUSION

Although SED women experienced poorer mental and overall health they reported similar health service needs and utilization patterns to more SEA women. The results can assist policy makers, health service planners and providers to develop and implement necessary and accessible services. Further research is needed to evaluate SED postpartum women's health service needs and barriers to service use.

[Introduction of the Birthcenter System (according to Belegsystem) in Germany--comments]

Recent years have undoubtedly been a time of dynamic changes for German midwives, which had had their source in numerous social, economic and political changes. The medical care cost growth, lack of profitability of medical centers and an increasing number of redundancies have been given lots of attention in various discussions. The above mentioned problems have started to concern the professional group of German midwives, thus giving birth to the introduction of innovatory system of obstetric care in German hospitals, known as Belegsystem. In Europe the Belegsystem has been introduced in certain Scandinavian countries, Great Britain, Austria and Switzerland. In Germany the first labour room within the Belegsystem rules has been opened on 1 June 2003 in Brema (Klinikum Bremerhaven Reinkenheide). The following two Centers have been opened in Hamburg at the beginning of 2004 (Allgemeines Krankenhaus Hamburg-Harburg i Allgemeines Krankenhaus Hamburg-Barmbek). The folllowing article presents the functioning rules and procedures of the Belegsystem labour rooms in Germany, as one of the labour care alternatives.

Costs and consequences of treatment for mild gestational diabetes mellitus - evaluation from the ACHOIS randomised trial

BACKGROUND

Recommended best practice is that economic evaluation of health care interventions should be integral with randomised clinical trials. We performed a cost-consequence analysis of treating women with mild gestational diabetes mellitus by dietary advice, blood glucose monitoring and insulin therapy as needed compared with routine pregnancy care, using patient-level data from a multi-centre randomised clinical trial.

METHODS

Women with a singleton pregnancy who had mild gestational diabetes diagnosed by an oral glucose-tolerance test between 24 and 34 weeks' gestation and their infants were included. Clinical outcomes and outpatient costs derived from all women and infants in the trial. Inpatient costs derived from women and infants attending the hospital contributing the largest number of enrolments (26.1%), and charges to women and their families derived from a subsample of participants from that hospital (in 2002 Australian dollars). Occasions of service and health outcomes were adjusted for maternal age, ethnicity and parity. Analysis of variance was used with bootstrapping to confirm results. Primary clinical outcomes were serious perinatal complications; admission to neonatal nursery; jaundice requiring phototherapy; induction of labour and caesarean delivery. Economic outcome measures were outpatient and inpatient costs, and charges to women and their families.

RESULTS

For every 100 women with a singleton pregnancy and positive oral glucose tolerance test who were offered treatment for mild gestational diabetes mellitus in addition to routine obstetric care, $53,985 additional direct costs were incurred at the obstetric hospital, $6,521 additional charges were incurred by women and their families, 9.7 additional women experienced induction of labour, and 8.6 more babies were admitted to a neonatal nursery. However, 2.2 fewer babies experienced serious perinatal complication and 1.0 fewer babies experienced perinatal death. The incremental cost per additional serious perinatal complication prevented was $27,503, per perinatal death prevented was $60,506 and per discounted life-year gained was $2,988.

CONCLUSION

It is likely that the general public in high-income countries such as Australia would find reductions in perinatal mortality and in serious perinatal complications sufficient to justify additional health service and personal monetary charges. Over the whole lifespan, the incremental cost per extra life-year gained is highly favourable.

Income inequalities and self-reported maternal health status: cross-sectional national survey

The objective of this study was to examine income inequalities in the self-reported health status of women during the postnatal period. We analysed data from a cohort of 18,523 birth mothers of children who participated in the Millennium Cohort Study. Data on income and self-reported health status were collected during face-to-face interviews conducted at 9 months postpartum. Total take-home household income from employment, government and other sources was estimated and equivalised to reflect household composition, while self-reported health status was converted into a dichotomous measure. Complex survey logistic regression models were used to explore the association between equivalised household income and fair or poor self-reported health status. Compared with mothers with equivalised household income in the first quintile (bottom 20%) of the income distribution, mothers in the third (OR 0.69; 95% CI 0.59-0.81), fourth (OR 0.43; 95% CI 0.38-0.50) and fifth (OR 0.32; 95% CI 0.27-0.37) quintiles had a decreased likelihood of reporting fair or poor health status (P < 0.001). However, following adjustment for other predictors of postnatal health status, only mothers with equivalised household income in the fifth quintile (top 20%) had a decreased likelihood of reporting fair or poor health status (OR 0.72; 95% CI 0.58-0.90; P = 0.004). We conclude that this study provides support for the existence of an income gradient for postnatal health status. Efforts to reduce income inequalities in adverse maternal health outcomes are likely to require macro and microeconomic initiatives.

Disproportionate Intrauterine Growth Intervention Trial At Term: DIGITAT

Background

Around 80% of intrauterine growth restricted (IUGR) infants are born at term. They have an increase in perinatal mortality and morbidity including behavioral problems, minor developmental delay and spastic cerebral palsy. Management is controversial, in particular the decision whether to induce labour or await spontaneous delivery with strict fetal and maternal surveillance. We propose a randomised trial to compare effectiveness, costs and maternal quality of life for induction of labour versus expectant management in women with a suspected IUGR fetus at term.

Methods/design

The proposed trial is a multi-centre randomised study in pregnant women who are suspected on clinical grounds of having an IUGR child at a gestational age between 36+0 and 41+0 weeks. After informed consent women will be randomly allocated to either induction of labour or expectant management with maternal and fetal monitoring. Randomisation will be web-based. The primary outcome measure will be a composite neonatal morbidity and mortality. Secondary outcomes will be severe maternal morbidity, maternal quality of life and costs. Moreover, we aim to assess neurodevelopmental and neurobehavioral outcome at two years as assessed by a postal enquiry (Child Behavioral Check List-CBCL and Ages and Stages Questionnaire-ASQ). Analysis will be by intention to treat. Quality of life analysis and a preference study will also be performed in the same study population. Health technology assessment with an economic analysis is part of this so called Digitat trial (Disproportionate Intrauterine Growth Intervention Trial At Term). The study aims to include 325 patients per arm.

Discussion

This trial will provide evidence for which strategy is superior in terms of neonatal and maternal morbidity and mortality, costs and maternal quality of life aspects. This will be the first randomised trial for IUGR at term.

Longitudinal effects of domestic violence on employment and welfare outcomes

This study uses longitudinal data spanning 13 years from a study of 234 adolescent mothers to evaluate the effects of cumulative domestic violence on employment and welfare use before and after welfare reform. Domestic violence increased the odds of unemployment after welfare reform, but not before; domestic violence had no effect on welfare use during any time period. Psychological distress after welfare reform was associated with unemployment, but not with welfare outcomes. Thus, the authors found that the direct effect of domestic violence on unemployment is not mediated by concurrent level of psychological distress. The relationship of psychological distress to unemployment exists only for those with a history of domestic violence. Cumulative domestic violence can have negative effects on economic capacity many years after the violence occurs, suggesting that policymakers recognize the long-term nature of the impact of domestic violence on women's capacity to be economically self-reliant.
