Article: Women's groups practising participatory learning and action to improve maternal and newborn health in low-resource settings: a systematic review and meta-analysis
[show abstract] [hide abstract]
ABSTRACT: 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 (119428 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 (I2=58·8%, p=0·024) and neonatal results (I2=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.Lancet. 05/2013; 381(18 May):1736–46. -
Article: 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.
[show abstract] [hide abstract]
ABSTRACT: BACKGROUND: Women's 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 women's 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 women's 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 women's 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 women's groups, and in areas with women's 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 women's groups was US$114 per year of life lost (YLL) averted and that of peer counsellors was $33 per YLL averted, using stratified data from single intervention comparisons. INTERPRETATION: Community mobilisation through women's groups and volunteer peer counsellor health education are methods to improve maternal and child health outcomes in poor rural populations in Africa.

Article: Nutritional status of young children in Mumbai slums: a follow-up anthropometric study.
[show abstract] [hide abstract]
ABSTRACT: BACKGROUND: Chronic childhood malnutrition remains common in India. As part of an initiative to improve maternal and child health in urban slums, we collected anthropometric data from a sample of children followed up from birth. We described the proportions of underweight, stunting, and wasting in young children, and examined their relationships with age. METHODS: We used two linked datasets: one based on institutional birth weight records for 17 318 infants, collected prospectively, and one based on follow-up of a subsample of 1941 children under five, collected in early 2010. RESULTS: Mean birth weight was 2736 g (SD 530 g), with a low birth weight (<2500 g) proportion of 22%. 21% of infants had low weight for age standard deviation (z) scores at birth (<-2 SD). At follow-up, 35% of young children had low weight for age, 17% low weight for height, and 47% low height for age. Downward change in weight for age was greater in children who had been born with higher z scores. DISCUSSION: Our data support the idea that much of growth faltering was explained by faltering in height for age, rather than by wasting. Stunting appeared to be established early and the subsequent decline in height for age was limited. Our findings suggest a focus on a younger age-group than the children over the age of three who are prioritized by existing support systems.FundingThe trial during which the birth weight data were collected was funded by the ICICI Foundation for Inclusive Growth (Centre for Child Health and Nutrition), and The Wellcome Trust (081052/Z/06/Z). Subsequent collection, analysis and development of the manuscript was funded by a Wellcome Trust Strategic Award: Population Science of Maternal and Child Survival (085417ma/Z/08/Z).

Article: Community mobilization in Mumbai slums to improve perinatal care and outcomes: a cluster randomized controlled trial.
[show abstract] [hide abstract]
ABSTRACT: Improving maternal and newborn health in low-income settings requires both health service and community action. Previous community initiatives have been predominantly rural, but India is urbanizing. While working to improve health service quality, we tested an intervention in which urban slum-dweller women's groups worked to improve local perinatal health. A cluster randomized controlled trial in 24 intervention and 24 control settlements covered a population of 283,000. In each intervention cluster, a facilitator supported women's groups through an action learning cycle in which they discussed perinatal experiences, improved their knowledge, and took local action. We monitored births, stillbirths, and neonatal deaths, and interviewed mothers at 6 weeks postpartum. The primary outcomes described perinatal care, maternal morbidity, and extended perinatal mortality. The analysis included 18,197 births over 3 years from 2006 to 2009. We found no differences between trial arms in uptake of antenatal care, reported work, rest, and diet in later pregnancy, institutional delivery, early and exclusive breastfeeding, or care-seeking. The stillbirth rate was non-significantly lower in the intervention arm (odds ratio 0.86, 95% CI 0.60-1.22), and the neonatal mortality rate higher (1.48, 1.06-2.08). The extended perinatal mortality rate did not differ between arms (1.19, 0.90-1.57). We have no evidence that these differences could be explained by the intervention. Facilitating urban community groups was feasible, and there was evidence of behaviour change, but we did not see population-level effects on health care or mortality. In cities with multiple sources of health care, but inequitable access to services, community mobilization should be integrated with attempts to deliver services for the poorest and most vulnerable, and with initiatives to improve quality of care in both public and private sectors.

Article: Volunteer infant feeding and care counselors: a health education intervention to improve mother and child health and reduce mortality in rural Malawi.
[show abstract] [hide abstract]
ABSTRACT: The aim of this report is to describe a health education intervention involving volunteer infant feeding and care counselors being implemented in Mchinji district, Malawi. The intervention was established in January 2004 and involves 72 volunteer infant feeding and care counselors, supervised by 24 government Health Surveillance Assistants, covering 355 villages in Mchinji district. It aims to change the knowledge, attitudes and behaviour of women to promote exclusive breastfeeding and other infant care practices. The main target population are women of child bearing age who are visited at five key points during pregnancy and after birth. Where possible, their partners are also involved. The visits cover exclusive breastfeeding and other important neonatal and infant care practices. Volunteers are provided with an intervention manual and picture book. Resource inputs are low and include training allowances and equipment for counselors and supervisors, and a salary, equipment and materials for a coordinator. It is hypothesized that the counselors will encourage informational and attitudinal change to enhance motivation and risk reduction skills and self-efficacy to promote exclusive breastfeeding and other infant care practices and reduce infant mortality. The impact is being evaluated through a cluster randomised controlled trial and results will be reported in 2012.Malawi medical journal: the journal of Medical Association of Malawi 06/2012; 24(2):39-42. -
Article: Stillbirths and newborn deaths in slum settlements in Mumbai, India: a prospective verbal autopsy study.
[show abstract] [hide abstract]
ABSTRACT: Three million babies are stillborn each year and 3.6 million die in the first month of life. In India, early neonatal deaths make up four-fifths of neonatal deaths and infant mortality three-quarters of under-five mortality. Information is scarce on cause-specific perinatal and neonatal mortality in urban settings in low-income countries. We conducted verbal autopsies for stillbirths and neonatal deaths in Mumbai slum settlements. Our objectives were to classify deaths according to international cause-specific criteria and to identify major causes of delay in seeking and receiving health care for maternal and newborn health problems. Over two years, 2005-2007, births and newborn deaths in 48 slum areas were identified prospectively by local informants. Verbal autopsies were collected by trained field researchers, cause of death was classified by clinicians, and family narratives were analysed to investigate delays on the pathway to mortality. Of 105 stillbirths, 65 were fresh (62%) and obstetric complications dominated the cause classification. Of 116 neonatal deaths, 87 were early and the major causes were intrapartum-related (28%), prematurity (23%), and severe infection (22%). Bereavement was associated with socioeconomic quintile, previous stillbirth, and number of antenatal care visits. We identified 201 individual delays in 121/187 birth narratives (65%). Overall, delays in receiving care after arrival at a health facility dominated and were mostly the result of referral from one institution to another. Most delays in seeking care were attributed to a failure to recognise symptoms of complications or their severity. In Mumbai's slum settlements, early neonatal deaths made up 75% of neonatal deaths and intrapartum-related complications were the greatest cause of mortality. Delays were identified in two-thirds of narratives, were predominantly related to the provision of care, and were often attributable to referrals between health providers. There is a need for clear protocols for care and transfer at each level of the health system, and an emphasis on rapid identification of problems and communication between health facilities.

Article: Association between clean delivery kit use, clean delivery practices, and neonatal survival: pooled analysis of data from three sites in South Asia.
[show abstract] [hide abstract]
ABSTRACT: Sepsis accounts for up to 15% of an estimated 3.3 million annual neonatal deaths globally. We used data collected from the control arms of three previously conducted cluster-randomised controlled trials in rural Bangladesh, India, and Nepal to examine the association between clean delivery kit use or clean delivery practices and neonatal mortality among home births. Hierarchical, logistic regression models were used to explore the association between neonatal mortality and clean delivery kit use or clean delivery practices in 19,754 home births, controlling for confounders common to all study sites. We tested the association between kit use and neonatal mortality using a pooled dataset from all three sites and separately for each site. We then examined the association between individual clean delivery practices addressed in the contents of the kit (boiled blade and thread, plastic sheet, gloves, hand washing, and appropriate cord care) and neonatal mortality. Finally, we examined the combined association between mortality and four specific clean delivery practices (boiled blade and thread, hand washing, and plastic sheet). Using the pooled dataset, we found that kit use was associated with a relative reduction in neonatal mortality (adjusted odds ratio 0.52, 95% CI 0.39-0.68). While use of a clean delivery kit was not always accompanied by clean delivery practices, using a plastic sheet during delivery, a boiled blade to cut the cord, a boiled thread to tie the cord, and antiseptic to clean the umbilicus were each significantly associated with relative reductions in mortality, independently of kit use. Each additional clean delivery practice used was associated with a 16% relative reduction in neonatal mortality (odds ratio 0.84, 95% CI 0.77-0.92). The appropriate use of a clean delivery kit or clean delivery practices is associated with relative reductions in neonatal mortality among home births in underserved, rural populations.PLoS Medicine 02/2012; 9(2):e1001180. · 16.27 Impact Factor -
Article: Intracluster correlation coefficients and coefficients of variation for perinatal outcomes from five cluster-randomised controlled trials in low and middle-income countries: results and methodological implications.
[show abstract] [hide abstract]
ABSTRACT: Public health interventions are increasingly evaluated using cluster-randomised trials in which groups rather than individuals are allocated randomly to treatment and control arms. Outcomes for individuals within the same cluster are often more correlated than outcomes for individuals in different clusters. This needs to be taken into account in sample size estimations for planned trials, but most estimates of intracluster correlation for perinatal health outcomes come from hospital-based studies and may therefore not reflect outcomes in the community. In this study we report estimates for perinatal health outcomes from community-based trials to help researchers plan future evaluations. We estimated the intracluster correlation and the coefficient of variation for a range of outcomes using data from five community-based cluster randomised controlled trials in three low-income countries: India, Bangladesh and Malawi. We also performed a simulation exercise to investigate the impact of cluster size and number of clusters on the reliability of estimates of the coefficient of variation for rare outcomes. Estimates of intracluster correlation for mortality outcomes were lower than those for process outcomes, with narrower confidence intervals throughout for trials with larger numbers of clusters. Estimates of intracluster correlation for maternal mortality were particularly variable with large confidence intervals. Stratified randomisation had the effect of reducing estimates of intracluster correlation. The simulation exercise showed that estimates of intracluster correlation are much less reliable for rare outcomes such as maternal mortality. The size of the cluster had a greater impact than the number of clusters on the reliability of estimates for rare outcomes. The breadth of intracluster correlation estimates reported here in terms of outcomes and contexts will help researchers plan future community-based public health interventions around maternal and newborn health. Our study confirms previous work finding that estimates of intracluster correlation are associated with the prevalence of the outcome of interest, the nature of the outcome of interest (mortality or behavioural) and the size and number of clusters. Estimates of intracluster correlation for maternal mortality need to be treated with caution and a range of estimates should be used in planning future trials.Trials 06/2011; 12:151. · 2.02 Impact Factor -
Article: Community interventions to reduce child mortality in Dhanusha, Nepal: study protocol for a cluster randomized controlled trial.
[show abstract] [hide abstract]
ABSTRACT: BACKGROUND: Neonatal mortality remains high in rural Nepal. Previous work suggests that local women's groups can effect significant improvement through community mobilisation. The possibility of identification and management of newborn infections by community-based workers has also arisen. METHODS/DESIGN: The objective of this trial is to evaluate the effects on newborn health of two community-based interventions involving Female Community Health Volunteers. MIRA Dhanusha community groups: a participatory intervention with women's groups. MIRA Dhanusha sepsis management: training of community volunteers in the recognition and management of neonatal sepsis.The study design is a cluster randomized controlled trial involving 60 village development committee clusters allocated 1:1 to two interventions in a factorial design. MIRA Dhanusha community groups: Female Community Health Volunteers (FCHVs) are supported in convening monthly women's groups. Nine groups per cluster (270 in total) work through two action research cycles in which they (i) identify local issues around maternity, newborn health and nutrition, (ii) prioritize key problems, (iii) develop strategies to address them, (iv) implement the strategies, and (v) evaluate their success. Cycle 1 focuses on maternal and newborn health and cycle 2 on nutrition in pregnancy and infancy and associated postpartum care practices. MIRA Dhanusha sepsis management: FCHVs are trained to care for vulnerable newborn infants. They (i) identify local births, (ii) identify low birth weight infants, (iii) identify possible newborn infection, (iv) manage the process of treatment with oral antibiotics and referral to a health facility to receive parenteral gentamicin, and (v) follow up infants and support families.Primary outcome: neonatal mortality rates. Secondary outcomes: MIRA Dhanusha community group: stillbirth, infant and under-two mortality rates, care practices and health care seeking behaviour, maternal diet, breastfeeding and complementary feeding practices, maternal and under-2 anthropometric status.

Article: A rapid assessment scorecard to identify informal settlements at higher maternal and child health risk in Mumbai.
[show abstract] [hide abstract]
ABSTRACT: The communities who live in urban informal settlements are diverse, as are their environmental conditions. Characteristics include inadequate access to safe water and sanitation, poor quality of housing, overcrowding, and insecure residential status. Interventions to improve health should be equity-driven and target those at higher risk, but it is not clear how to prioritise informal settlements for health action. In implementing a maternal and child health programme in Mumbai, India, we had conducted a detailed vulnerability assessment which, though important, was time-consuming and may have included collection of redundant information. Subsequent data collection allowed us to examine three issues: whether community environmental characteristics were associated with maternal and newborn healthcare and outcomes; whether it was possible to develop a triage scorecard to rank the health vulnerability of informal settlements based on a few rapidly observable characteristics; and whether the scorecard might be useful for future prioritisation. The City Initiative for Newborn Health documented births in 48 urban slum areas over 2 years. Information was collected on maternal and newborn care and mortality, and also on household and community environment. We selected three outcomes-less than three antenatal care visits, home delivery, and neonatal mortality-and used logistic regression and classification and regression tree analysis to test their association with rapidly observable environmental characteristics. We developed a simple triage scorecard and tested its utility as a means of assessing maternal and newborn health risk. In analyses on a sample of 10,754 births, we found associations of health vulnerability with inadequate access to water, toilets, and electricity; non-durable housing; hazardous location; and rental tenancy. A simple scorecard based on these had limited sensitivity and positive predictive value, but relatively high specificity and negative predictive value. The scorecard needs further testing in a range of urban contexts, but we intend to use it to identify informal settlements in particular need of family health interventions in a subsequent program.Journal of Urban Health 04/2011; 88(5):919-32. · 2.13 Impact Factor -
Article: Maternal and neonatal health expenditure in Mumbai slums (India): a cross sectional study.
[show abstract] [hide abstract]
ABSTRACT: The 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. We 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). A 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. High 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.BMC Public Health 03/2011; 11:150. · 2.00 Impact Factor -

Article: Community mobilisation and health management committee strengthening to increase birth attendance by trained health workers in rural Makwanpur, Nepal: study protocol for a cluster randomised controlled trial.
[show abstract] [hide abstract]
ABSTRACT: BACKGROUND: Birth attendance by trained health workers is low in rural Nepal. Local participation in improving health services and increased interaction between health systems and communities may stimulate demand for health services. Significant increases in birth attendance by trained health workers may be affected through community mobilisation by local women's groups and health management committee strengthening. We will test the effect of community mobilisation through women's groups, and health management committee strengthening, on institutional deliveries and home deliveries attended by trained health workers in Makwanpur District. DESIGN: Cluster randomised controlled trial involving 43 village development committee clusters. 21 clusters will receive the intervention and 22 clusters will serve as control areas. In intervention areas, Female Community Health Volunteers are supported in convening monthly women's groups. The groups work through an action research cycle in which they consider barriers to institutional delivery, plan and implement strategies to address these barriers with their communities, and evaluate their progress. Health management committees participate in three-day workshops that use appreciative inquiry methods to explore and plan ways to improve maternal and newborn health services. Follow-up meetings are conducted every three months to review progress. Primary outcomes are institutional deliveries and home deliveries conducted by trained health workers. Secondary outcome measures include uptake of antenatal and postnatal care, neonatal mortality and stillbirth rates, and maternal morbidity.

Article: Adaptation of a probabilistic method (InterVA) of verbal autopsy to improve the interpretation of cause of stillbirth and neonatal death in Malawi, Nepal, and Zimbabwe.
[show abstract] [hide abstract]
ABSTRACT: Verbal autopsy (VA) is a widely used method for analyzing cause of death in absence of vital registration systems. We adapted the InterVA method to extrapolate causes of death for stillbirths and neonatal deaths from verbal autopsy questionnaires, using data from Malawi, Zimbabwe, and Nepal. We obtained 734 stillbirth and neonatal VAs from recent community studies in rural areas: 169 from Malawi, 385 from Nepal, and 180 from Zimbabwe. Initial refinement of the InterVA model was based on 100 physician-reviewed VAs from Malawi. InterVA indicators and matrix probabilities for cause of death were reviewed for clinical and epidemiological coherence by a pediatrician-researcher and an epidemiologist involved in the development of InterVA. The modified InterVA model was evaluated by comparing population-level cause-specific mortality fractions and individual agreement from two methods of interpretation (physician review and InterVA) for a further 69 VAs from Malawi, 385 from Nepal, and 180 from Zimbabwe. Case-by-case agreement between InterVA and reviewing physician diagnoses for 69 cases from Malawi, 180 cases from Zimbabwe, and 385 cases from Nepal were 83% (kappa 0.76 (0.75 - 0.80)), 71% (kappa 0.41(0.32-0.51)), and 74% (kappa 0.63 (0.60-0.63)), respectively. The proportion of stillbirths identified as fresh or macerated by the different methods of VA interpretation was similar in all three settings. Comparing across countries, the modified InterVA method found that proportions of preterm births and deaths due to infection were higher in Zimbabwe (44%) than in Malawi (28%) or Nepal (20%). The modified InterVA method provides plausible results for stillbirths and newborn deaths, broadly comparable to physician review but with the advantage of internal consistency. The method allows standardized cross-country comparisons and eliminates the inconsistencies of physician review in such comparisons.Population Health Metrics 01/2011; 9:48. · 2.11 Impact Factor -
Article: MaiMwana women's groups: a community mobilisation intervention to improve mother and child health and reduce mortality in rural Malawi.
[show abstract] [hide abstract]
ABSTRACT: This article presents a detailed description of a community mobilization intervention involving women's groups in Mchinji District, Malawi. The intervention was implemented between 2005 and 2010. The intervention aims to build the capacities of communities to take control of the mother and child health issues that affect them. To achieve this it comprises trained local female facilitators establishing groups and using a manual, participatory rural appraisal tools and picture cards to guide them through a community action cycle to identify and implement solutions to mother and child health problems. Significant resource inputs include salaries for facilitators and supervisors, and training, equipment and materials to support their work with groups. It is hypothesized that the groups will catalyse community collective action to address mother and child health issues and improve the health and reduce the mortality of mothers and children. Their impact, implementation and cost-effectiveness have been rigorously evaluated through a randomized controlled trial design. The results of these evaluations will be reported in 2011.Malawi medical journal: the journal of Medical Association of Malawi 12/2010; 22(4):112-9. -
Article: Perinatal interventions and survival in resource-poor settings: which work, which don't, which have the jury out?
[show abstract] [hide abstract]
ABSTRACT: Perinatal conditions make the largest contribution to the burden of disease in low-income countries. Although postneonatal mortality rates have declined, stillbirth and early neonatal mortality rates remain high in many countries in Africa and Asia, and there is a concentration of mortality around the time of birth. Our article begins by considering differences in the interpretation of 'intervention' to improve perinatal survival. We identify three types of INTERVENTION: a single action, a collection of actions delivered in a package and a broader social or system approach. We use this classification to summarise the findings of recent systematic reviews and meta-analyses. After describing the growing evidence base for the effectiveness of community-based perinatal care, we discuss current concerns about integration: of women's and children's health programmes, of community-based and institutional care, and of formal and informal sector human resources. We end with some thoughts on the complexity of choices confronting women and their families in low-income countries, particularly in view of the growth in non-government and private sector healthcare.Archives of Disease in Childhood 10/2010; 95(12):1039-46. · 2.88 Impact Factor -
Article: Spoilt for choice? Cross-sectional study of care-seeking for health problems during pregnancy in Mumbai slums.
[show abstract] [hide abstract]
ABSTRACT: This study considers care-seeking patterns for maternal morbidity in Mumbai's slums. Our objectives were to document women's self-reported symptoms and care-seeking, and to quantify their choice of health provider, care-seeking delays and referrals between providers. The hypothesis that care-seeking sites for maternal morbidity mirror those used for antenatal care was also tested. We analysed data for 10,754 births in 48 slum areas and interviewed mothers about their illnesses and care-seeking during pregnancy. Institutional care-seeking was high across the board (>80%), and higher for 'trigger' symptoms suggestive of complications (>88%). Private-sector care was preferred, and increased with socio-economic status, although public providers also played an important role. Most women sought treatment at the same site they received their antenatal care, most were treated within 2 days, and less than 2% were referred to other providers. Our findings suggest that poor women in Mumbai recognise symptoms of obstetric complications and the need for health care. However, that more than 80% also sought care for minor conditions implies that the tendency to seek institutional care for serious conditions reflects a broader picture of care-seeking for all illnesses. The role of private health-care providers needs greater recognition, and further research is required on provider motivations and behaviour.Global Public Health 10/2010; 6(7):746-59. · 0.92 Impact Factor -
