Women's groups practising participatory learning and action to improve maternal and newborn health in low-resource settings: a systematic review and meta-analysis

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 womens 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 womens 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 womens 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 womens 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, womens groups practising participatory learning and action are a cost-effective strategy to improve maternal and neonatal survival in low-resource settings.

Effect of women's groups and volunteer peer counselling on rates of mortality, morbidity, and health behaviours in mothers and children in rural Malawi (MaiMwana): a factorial, cluster-randomised controlled trial

BACKGROUND Womens groups and health education by peer counsellors can improve the health of mothers and children. We assessed their effects on mortality and breastfeeding rates in rural Malawi. METHODS We did a 2×2 factorial, cluster-randomised trial in 185,888 people in Mchinji district. 48 equal-sized clusters were randomly allocated to four groups with a computer-generated number sequence. 24 facilitators guided groups through a community action cycle to tackle maternal and child health problems. 72 trained volunteer peer counsellors made home visits at five timepoints during pregnancy and after birth to support breastfeeding and infant care. Primary outcomes for the womens group intervention were maternal, perinatal, neonatal, and infant mortality rates (MMR, PMR, NMR, and IMR, respectively); and for the peer counselling were IMR and exclusive breastfeeding (EBF) rates. Analysis was by intention to treat. The trial is registered as ISRCTN06477126. FINDINGS We monitored outcomes of 26,262 births between 2005 and 2009. In a factorial model adjusted only for clustering and the volunteer peer counselling intervention, in womens group areas, for years 2 and 3, we noted non-significant decreases in NMR (odds ratio 0.93, 0.64-1.35) and MMR (0.54, 0.28-1.04). After adjustment for parity, socioeconomic quintile, and baseline measures, effects were larger for NMR (0.85, 0.59-1.22) and MMR (0.48, 0.26-0.91). Because of the interaction between the two interventions, a stratified analysis was done. For womens groups, in adjusted analyses, MMR fell by 74% (0.26, 0.10-0.70), and NMR by 41% (0.59, 0.40-0.86) in areas with no peer counsellors, but there was no effect in areas with counsellors (1.09, 0.40-2.98, and 1.38, 0.75-2.54). Factorial analysis for the peer counselling intervention for years 1-3 showed a fall in IMR of 18% (0.82, 0.67-1.00) and an improvement in EBF rates (2.42, 1.48-3.96). The results of the stratified, adjusted analysis showed a 36% reduction in IMR (0.64, 0.48-0.85) but no effect on EBF (1.18, 0.63-2.25) in areas without womens groups, and in areas with womens groups there was no effect on IMR (1.05, 0.82-1.36) and an increase in EBF (5.02, 2.67-9.44). The cost of womens groups was US

Maternal and neonatal health expenditure in mumbai slums (India): A cross sectional study

IMPORTANCE Community-based interventions can reduce neonatal mortality when health systems are weak. Population coverage of target groups may be an important determinant of their effect on behavior and mortality. A womens group trial at coverage of 1 group per 1414 population in rural Bangladesh showed no effect on neonatal mortality, despite a similar intervention having a significant effect on neonatal and maternal death in comparable settings. OBJECTIVE To assess the effect of a participatory womens group intervention with higher population coverage on neonatal mortality in Bangladesh. DESIGN A cluster randomized controlled trial in 9 intervention and 9 control clusters. SETTING Rural Bangladesh. PARTICIPANTS Women permanently residing in 18 unions in 3 districts and accounting for 19 301 births during the final 24 months of the intervention. INTERVENTIONS Womens groups at a coverage of 1 per 309 population that proceed through a participatory learning and action cycle in which they prioritize issues that affected maternal and neonatal health and design and implement strategies to address these issues. MAIN OUTCOMES AND MEASURES Neonatal mortality rate. RESULTS Analysis included 19 301 births during the final 24 months of the intervention. More than one-third of newly pregnant women joined the groups. The neonatal mortality rate was significantly lower in the intervention arm (21.3 neonatal deaths per 1000 live births vs 30.1 per 1000 in control areas), a reduction in neonatal mortality of 38% (risk ratio, 0.62 [95% CI, 0.43-0.89]) when adjusted for socioeconomic factors. The cost-effectiveness was US

Collecting and analysing cost data for complex public health trials : reflections on practice

A pooled analysis of data from three studies in South Asia demonstrates an association between use of clean delivery kits during home births and reduced risk of neonatal mortality.

Highlighting the evidence gap: how cost-effective are interventions to improve early childhood nutrition and development?

BackgroundThe cost of maternity care can be a barrier to access that may increase maternal and neonatal mortality risk. We analyzed spending on maternity care in urban slum communities in Mumbai to better understand the equity of spending and the impact of spending on household poverty.MethodsWe used expenditure data for maternal and neonatal care, collected during post-partum interviews. Interviews were conducted in 2005-2006, with a sample of 1200 slum residents in Mumbai (India). We analysed expenditure by socio-economic status (SES), calculating a Kakwani Index for a range of spending categories. We also calculated catastrophic health spending both with and without adjustment for coping strategies. This identified the level of catastrophic payments incurred by a household and the prevalence of catastrophic payments in this population. The analysis also gave an understanding of the protection from medical poverty afforded by coping strategies (for example saving and borrowing).ResultsA high proportion of respondents spent catastrophically on care. Lower SES was associated with a higher proportion of informal payments. Indirect health expenditure was found to be (weakly) regressive as the poorest were more likely to use wage income to meet health expenses, while the less poor were more likely to use savings. Overall, the incidence of catastrophic maternity expenditure was 41%, or 15% when controlling for coping strategies. We found no significant difference in the incidence of catastrophic spending across wealth quintiles, nor could we conclude that total expenditure is regressive.ConclusionsHigh expenditure as a proportion of household resources should alert policymakers to the burden of maternal spending in this context. Differences in informal payments, significantly regressive indirect spending and the use of savings versus wages to finance spending, all highlight the heavier burden borne by the most poor. If a policy objective is to increase institutional deliveries without forcing households deeper into poverty, these inequities will need to be addressed. Reducing out-of-pocket payments and better regulating informal payments should have direct benefits for the most poor. Alternatively, targeted schemes aimed at assisting the most poor in coping with maternal spending (including indirect spending) could reduce the household impact of high costs.

Experiences in running a complex electronic data capture system using mobile phones in a large-scale population trial in southern Nepal

BackgroundThe World Health Organization recommends that national malaria programmes universally distribute long-lasting insecticide-treated bed nets (LLINs). LLINs provide effective insecticide protection for at least three years while conventional nets must be retreated every 6-12 months. LLINs may also promise longer physical durability (lifespan), but at a higher unit price. No prospective data currently available is sufficient to calculate the comparative cost effectiveness of different net types. We thus constructed a model to explore the cost effectiveness of LLINs, asking how a longer lifespan affects the relative cost effectiveness of nets, and if, when and why LLINs might be preferred to conventional insecticide-treated nets. An innovation of our model is that we also considered the replenishment need i.e. loss of nets over time.MethodsWe modelled the choice of net over a 10-year period to facilitate the comparison of nets with different lifespan (and/or price) and replenishment need over time. Our base case represents a large-scale programme which achieves high coverage and usage throughout the population by distributing either LLINs or conventional nets through existing health services, and retreats a large proportion of conventional nets regularly at low cost. We identified the determinants of bed net programme cost effectiveness and parameter values for usage rate, delivery and retreatment cost from the literature. One-way sensitivity analysis was conducted to explicitly compare the differential effect of changing parameters such as price, lifespan, usage and replenishment need.ResultsIf conventional and long-lasting bed nets have the same physical lifespan (3 years), LLINs are more cost effective unless they are priced at more than USD 1.5 above the price of conventional nets. Because a longer lifespan brings delivery cost savings, each one year increase in lifespan can be accompanied by a USD 1 or more increase in price without the cheaper net (of the same type) becoming more cost effective. Distributing replenishment nets each year in addition to the replacement of all nets every 3-4 years increases the number of under-5 deaths averted by 5-14% at a cost of USD 17-25 per additional person protected per annum or USD 1080-1610 per additional under-5 death averted.ConclusionsOur results support the World Health Organization recommendation to distribute only LLINs, while giving guidance on the price thresholds above which this recommendation will no longer hold. Programme planners should be willing to pay a premium for nets which have a longer physical lifespan, and if planners are willing to pay USD 1600 per under-5 death averted, investing in replenishment is cost effective.
