Operationalizing safe operating space for regional social-ecological systems.

This study makes a first attempt to operationalize the safe operating space concept at a regional scale by considering the complex dynamics (e.g. non-linearity, feedbacks, and interactions) within a systems dynamic model (SD). We employ the model to explore eight 'what if' scenarios based on well-known challenges (e.g. climate change) and current policy debates (e.g. subsidy withdrawal). The findings show that the social-ecological system in the Bangladesh delta may move beyond a safe operating space when a withdrawal of a 50% subsidy for agriculture is combined with the effects of a 2°C temperature increase and sea level rise. Further reductions in upstream river discharge in the Ganges would push the system towards a dangerous zone once a 3.5°C temperature increase was reached. The social-ecological system in Bangladesh delta may be operated within a safe space by: 1) managing feedback (e.g. by reducing production costs) and the slow biophysical variables (e.g. temperature, rainfall) to increase the long-term resilience, 2) negotiating for transboundary water resources, and 3) revising global policies (e.g. withdrawal of subsidy) that negatively impact at regional scales. This study demonstrates how the concepts of tipping points, limits to adaptations, and boundaries for sustainable development may be defined in real world social-ecological systems.

Two decades of maternity care fee exemption policies in Ghana: have they benefited the poor?

OBJECTIVE: To investigate, the impact of maternity-related fee payment policies on the uptake of skilled birth care amongst the poor in Ghana. METHODS: Population data representing 12 288 births between November 1990 and October 2008 from four consecutive rounds of the Ghana demographic and health surveys were used to examine the impact of four major maternity-related payment policies: the full-cost recovery 'cash and carry' scheme; 'antenatal care fee exemption'; 'delivery care fee exemption' and the 'National Health Insurance Scheme (NHIS)'. Concentration curves were used to analyse the rich-poor gap in the use of skilled birth care by the four policy interventions. Multilevel logistic regression was used to examine the effect of the policies on the uptake of skilled birth care, adjusting for relevant predictors and clustering within communities and districts. FINDINGS: The uptake of skilled birth care over the policy periods for the poorest women was trivial when compared with their non-poor counterparts. The rich-poor gap in skilled birth care use was highly pronounced during the 'cash and carry' and 'free antenatal care' policies period. The benefits during the 'free delivery care' and ' NHIS' policy periods accrued more for the rich than the poor. There exist significant differences in skilled birth care use between and within communities and districts, even after adjusting for policy effects and other relevant predictors. CONCLUSIONS: The maternal care fee exemption policies specifically targeted towards the poorest women had limited impact on the uptake of skilled birth care.

Infrastructural challenges to better health in maternity facilities in rural Kenya: community and healthworker perceptions.

BACKGROUND: The efforts and commitments to accelerate progress towards the Millennium Development Goals for maternal and newborn health (MDGs 4 and 5) in low and middle income countries have focused primarily on providing key medical interventions at maternity facilities to save the lives of women at the time of childbirth, as well as their babies. However, in most rural communities in sub-Saharan, access to maternal and newborn care services is still limited and even where services are available they often lack the infrastructural prerequisites to function at the very basic level in providing essential routine health care services, let alone emergency care. Lists of essential interventions for normal and complicated childbirth, do not take into account these prerequisites, thus the needs of most health facilities in rural communities are ignored, although there is enough evidence that maternal and newborn deaths continue to remain unacceptably high in these areas. METHODS: This study uses data gathered through qualitative interviews in Kitonyoni and Mwania sub-locations of Makueni County in Eastern Kenya to understand community and provider perceptions of the obstacles faced in providing and accessing maternal and newborn care at health facilities in their localities. RESULTS: The study finds that the community perceives various challenges, most of which are infrastructural, including lack of electricity, water and poor roads that adversely impact the provision and access to essential life-saving maternal and newborn care services in the two sub-locations. CONCLUSIONS: The findings and recommendations from this study are important for the attention of policy makers and programme managers in order to improve the state of lower-tier health facilities serving rural communities and to strengthen infrastructure with the aim of making basic routine and emergency obstetric and newborn care services more accessible.

Evaluating the impact of the community-based health planning and services initiative on uptake of skilled birth care in Ghana.

BACKGROUND: The Community-based Health Planning and Services (CHPS) initiative is a major government policy to improve maternal and child health and accelerate progress in the reduction of maternal mortality in Ghana. However, strategic intelligence on the impact of the initiative is lacking, given the persistant problems of patchy geographical access to care for rural women. This study investigates the impact of proximity to CHPS on facilitating uptake of skilled birth care in rural areas. METHODS AND FINDINGS: Data from the 2003 and 2008 Demographic and Health Survey, on 4,349 births from 463 rural communities were linked to georeferenced data on health facilities, CHPS and topographic data on national road-networks. Distance to nearest health facility and CHPS was computed using the closest facility functionality in ArcGIS 10.1. Multilevel logistic regression was used to examine the effect of proximity to health facilities and CHPS on use of skilled care at birth, adjusting for relevant predictors and clustering within communities. The results show that a substantial proportion of births continue to occur in communities more than 8 km from both health facilities and CHPS. Increases in uptake of skilled birth care are more pronounced where both health facilities and CHPS compounds are within 8 km, but not in communities within 8 km of CHPS but lack access to health facilities. Where both health facilities and CHPS are within 8 km, the odds of skilled birth care is 16% higher than where there is only a health facility within 8km. CONCLUSION: Where CHPS compounds are set up near health facilities, there is improved access to care, demonstrating the facilitatory role of CHPS in stimulating access to better care at birth, in areas where health facilities are accessible.

Examining intersectoral integration for malaria control programmes in an urban and a rural district in Ghana: a multinomial multilevel analysis.

BACKGROUND: Intersectoral integration is acknowledged to be essential for improving provision of health care and outcomes, yet it remains one of the main primary health care strategic challenges. Although this is well articulated in the literature, the factors that explain differentials in levels of intersectoral integration have not been systematically studied, particularly in low and middle-income countries. In this study, we examine the levels and determinants of intersectoral integration amongst institutions engaged in malaria control programmes in an urban (Kumasi Metropolitan) district and a rural (Ahafo Ano South) district in Ghana. METHODS: Interviews were conducted with representatives of 32 institutions engaged in promoting malaria prevention and control. The averaging technique proposed by Brown et al. and a two-level multinomial multilevel ordinal logistic regression were used to examine the levels of integration and the factors that explain the differentials. RESULTS: The results show high disparity in levels of integration amongst institutions in the two districts. Integration was higher in the rural district compared to the urban district. The multivariate analysis revealed that the district effect explained 25% of the variations in integration. The type of institution, level of focus on malaria and source of funding are important predictors of intersectoral integration. CONCLUSION: Although not causal, integrated malaria control programmes could be important for improving malaria-related health outcomes in less developed regions as evident from the rapid decline in malaria fatality rates observed in the Ahafo Ano South district. Harmonisation of programmes should be encouraged amongst institutions and the public and private sectors should be motivated to work in partnership.

Geographical access to care at birth in Ghana: a barrier to safe motherhood.

BACKGROUND: Appropriate facility-based care at birth is a key determinant of safe motherhood but geographical access remains poor in many high burden regions. Despite its importance, geographical access is rarely audited systematically, preventing integration in national-level maternal health system assessment and planning. In this study, we develop a uniquely detailed set of spatially-linked data and a calibrated geospatial model to undertake a national-scale audit of geographical access to maternity care at birth in Ghana, a high-burden country typical of many in sub-Saharan Africa. METHODS: We assembled detailed spatial data on the population, health facilities, and landscape features influencing journeys. These were used in a geospatial model to estimate journey-time for all women of childbearing age (WoCBA) to their nearest health facility offering differing levels of care at birth, taking into account different transport types and availability. We calibrated the model using data on actual journeys made by women seeking care. RESULTS: We found that a third of women (34%) in Ghana live beyond the clinically significant two-hour threshold from facilities likely to offer emergency obstetric and neonatal care (EmONC) classed at the 'partial' standard or better. Nearly half (45%) live that distance or further from 'comprehensive' EmONC facilities, offering life-saving blood transfusion and surgery. In the most remote regions these figures rose to 63% and 81%, respectively. Poor levels of access were found in many regions that meet international targets based on facilities-per-capita ratios. CONCLUSIONS: Detailed data assembly combined with geospatial modelling can provide nation-wide audits of geographical access to care at birth to support systemic maternal health planning, human resource deployment, and strategic targeting. Current international benchmarks of maternal health care provision are inadequate for these purposes because they fail to take account of the location and accessibility of services relative to the women they serve.

Targeting women at risk of unintended pregnancy in Ghana: Should geography matter?

Unintended childbearing in Ghana is estimated to be about 0.7 births per woman, thus contributing to the high total fertility rate of more than 4 births. About one-third of women of reproductive age have an unmet need for family planning and there are strong geographic differences between and within ecological zones. Spatial analysis of risk of unintended pregnancies planning can reveal differences in the provision and usage of contraceptive commodities, thereby providing information of areas where programmes should be strengthened. This study uses data from the 1998 and 2003 Ghana Demographic and Health Surveys to examine geographical variation in the risk of unintended pregnancies among women in the three ecological zones of Ghana (Savannah, Forest, and Coastal). The data was analysed using multilevel logistic regression. Approximately 55% of Ghanaian women (married or in union) are at risk of unintended pregnancies and there are differences between urban and rural women, with rural women more likely to have their demand for contraception unmet. After adjusting for the socio-economic and demographic factors, the results show little differences between ecological zones in the levels of women exposed to the risk of unintended pregnancy, but they demonstrate significant within community effects, which influence the risk of unintended pregnancies for women within the community. Communities, therefore, can be used as units for targeting services aimed at increasing coverage of contraceptive commodities.

Maternal smoking and acute respiratory infection symptoms among young children in Nepal: multilevel analysis.

The association between maternal smoking and adverse child health outcomes has not been systematically explored in less developed countries, especially in Nepal where over a quarter of women of reproductive age smoke tobacco products. This study aims to quantify the effect of maternal smoking on acute respiratory infection (ARI) symptoms among children aged below five years, using the 2001 Nepal Demographic and Health Survey. It is hypothesized that children born to mothers who smoke frequently are at higher risk of developing ARI symptoms. Four-level random intercept logistic regression models were used to disentangle the independent effect of maternal smoking on children's ARI symptoms, controlling for potential biological, socioeconomic, seasonal and spatial variables. Maternal smoking status had a significant effect on children's ARI symptoms; the effects were significantly higher (adjusted OR 1.41; 95% CI 1.02-1.96) among those born to mothers who smoked more frequently than their counterparts. Furthermore, a strong spatial pattern was evident in the prevalence of ARI symptoms, after adjusting for maternal smoking and relevant control variables. The findings underscore the importance of designing exclusive public health intervention measures to prevent tobacco smoking within households, for example through awareness campaigns highlighting the adverse effect of maternal smoking on child health.

On the spatial inequalities of institutional versus home births in Ghana: a multilevel analysis.

Spatial inequalities related to the choice of delivery care have not been studied systematically in Sub-Saharan Africa where maternal and perinatal health outcomes continue to worsen despite a range of safe motherhood interventions. Using retrospective data from the 1998 and 2003 Demographic and Health Surveys, this paper investigates the extent of changes in spatial inequalities associated with type of delivery care in Ghana with a focus on rural-urban differentials within and across the three ecological zones (Savannah, Forest and Coastal). More than one-half of births in Ghana continue to occur outside health institutions without any skilled obstetric care. While this is already known, we present evidence from multilevel analyses that there exist considerable and growing inequalities, with regard to birth settings between communities, within rural and urban areas and across the ecological zones. The results show evidence of poor and disproportionate use of institutional care at birth; the inequalities remained high and unchanged in both urban and rural communities within the Savannah zone and widening in urban communities of the Forest and Coastal zones. The key policy challenges in Ghana, therefore, include both increasing the uptake of institutional delivery care and ensuring equity in access to both public and private health institutions.
