The impact of a complex school nutrition intervention on double burden of malnutrition among Thai primary school children: a 2-year quasi-experiment

OBJECTIVE

This study assessed the impacts of the Dekthai Kamsai programme on overweight/obesity, underweight and stunting among male and female primary school students.

STUDY DESIGN

A quasi-experiment was conducted in 16 intervention and 19 control schools across Thailand in 2018 and 2019. In total, 896 treated and 1779 control students from grades 1 to 3 were recruited. In intervention schools, a set of multifaceted intervention components were added into school routine practices. Anthropometric outcomes were measured at baseline and at the beginning and end of every school term.

METHODS

Propensity score matching with linear and Poisson difference-in-difference analyses were used to adjust for the non-randomisation and to analyse the intervention's effects over time.

RESULTS

Compared with controls, the increases in mean BMI-for-age Z-score (BAZ) and the incidence rate of overweight/obesity were lower in the intervention schools at the 3rd, 4th and 8th measurements and the 3rd measurement, respectively. The decrease in mean height-for-age Z-score (HAZ) was lower at the 4th measurement. The decrease in the incidence rate of wasting was lower at the 5th, 7th and 8th measurements. The favourable impacts on BAZ and HAZ were found in both sexes, while the favourable impact on overweight/obesity and unfavourable impact on wasting were found in girls.

CONCLUSIONS

This intervention might be effective in reducing BAZ, overweight/obesity, poor height gain, but not wasting. These findings highlight the benefits of a multifaceted school nutrition intervention and a need to incorporate tailor-made interventions for wasting to comprehensively address the double burden of malnutrition.

Measuring the economic burden for TB patients in the End TB Strategy and Universal Health Coverage frameworks

Tuberculosis (TB) is a disease of poverty. Ensuring access to health care without the risk of financial hardship due to out-of-pocket health care expenditures (Universal Health Coverage [UHC]) is essential for providing accessible care to underprivileged populations, but this is not enough. The End TB Strategy promotes both patient-centred TB services and social protection measures, which aim to mitigate the economic hardship faced by TB patients and their households due to direct medical and non-medical expenditures, as well as to lost income. The strategy includes a target that no families should face catastrophic total costs due to TB. The indicator linked to this target aims to capture the total economic burden linked to TB care, and thus differs from the 'catastrophic expenditure on health' indicator, a key component of the UHC monitoring framework aligned with the Sustainable Development Goals. Countries, and particularly high TB burden countries, are expected to conduct nationally representative TB patient cost surveys to establish baseline measurements for the catastrophic costs indicator. Findings from these surveys should also help identify entry points for developing policies to ensure better financial and social protection for TB patients. In this paper, we define the key measurable concepts for TB patient cost surveys, notably the types of costs that are captured, and related affordability measures. We discuss methods for measuring these notions in the UHC framework and contrast them with how they are measured in TB patient cost surveys.

How to do (or not to do)… Measuring health worker motivation in surveys in low- and middle-income countries

A health system's ability to deliver quality health care depends on the availability of motivated health workers, which are insufficient in many low income settings. Increasing policy and researcher attention is directed towards understanding what drives health worker motivation and how different policy interventions affect motivation, as motivation is key to performance and quality of care outcomes. As a result, there is growing interest among researchers in measuring motivation within health worker surveys. However, there is currently limited guidance on how to conceptualize and approach measurement and how to validate or analyse motivation data collected from health worker surveys, resulting in inconsistent and sometimes poor quality measures. This paper begins by discussing how motivation can be conceptualized, then sets out the steps in developing questions to measure motivation within health worker surveys and in ensuring data quality through validity and reliability tests. The paper also discusses analysis of the resulting motivation measure/s. This paper aims to promote high quality research that will generate policy relevant and useful evidence.

Using stakeholder analysis to support moves towards universal coverage: lessons from the SHIELD project

Stakeholder analysis is widely recommended as a tool for gathering insights on policy actor interests in, positions on, and power to influence, health policy issues. Such information is recognized to be critical in developing viable health policy proposals, and is particularly important for new health care financing proposals that aim to secure universal coverage (UC). However, there remain surprisingly few published accounts of the use of stakeholder analysis in health policy development generally, and health financing specifically, and even fewer that draw lessons from experience about how to do and how to use such analysis. This paper, therefore, aims to support those developing or researching UC reforms to think both about how to conduct stakeholder analysis, and how to use it to support evidence-informed pro-poor health policy development. It presents practical lessons and ideas drawn from experience of doing stakeholder analysis around UC reforms in South Africa and Tanzania, combined with insights from other relevant material. The paper has two parts. The first presents lessons of experience for conducting a stakeholder analysis, and the second, ideas about how to use the analysis to support policy design and the development of actor and broader political management strategies. Comparison of experience across South Africa and Tanzania shows that there are some commonalities concerning which stakeholders have general interests in UC reform. However, differences in context and in reform proposals generate differences in the particular interests of stakeholders and their likely positioning on reform proposals, as well as in their relative balance of power. It is, therefore, difficult to draw cross-national policy comparisons around these specific issues. Nonetheless, the paper shows that cross-national policy learning is possible around the approach to analysis, the factors influencing judgements and the implications for, and possible approaches to, management of policy processes. Such learning does not entail generalization about which UC reform package offers most gain in any setting, but rather about how to manage the reform process within a particular context.

Equity in financing and use of health care in Ghana, South Africa, and Tanzania: implications for paths to universal coverage

BACKGROUND

Universal coverage of health care is now receiving substantial worldwide and national attention, but debate continues on the best mix of financing mechanisms, especially to protect people outside the formal employment sector. Crucial issues are the equity implications of different financing mechanisms, and patterns of service use. We report a whole-system analysis--integrating both public and private sectors--of the equity of health-system financing and service use in Ghana, South Africa, and Tanzania.

METHODS

We used primary and secondary data to calculate the progressivity of each health-care financing mechanism, catastrophic spending on health care, and the distribution of health-care benefits. We collected qualitative data to inform interpretation.

FINDINGS

Overall health-care financing was progressive in all three countries, as were direct taxes. Indirect taxes were regressive in South Africa but progressive in Ghana and Tanzania. Out-of-pocket payments were regressive in all three countries. Health-insurance contributions by those outside the formal sector were regressive in both Ghana and Tanzania. The overall distribution of service benefits in all three countries favoured richer people, although the burden of illness was greater for lower-income groups. Access to needed, appropriate services was the biggest challenge to universal coverage in all three countries.

INTERPRETATION

Analyses of the equity of financing and service use provide guidance on which financing mechanisms to expand, and especially raise questions over the appropriate financing mechanism for the health care of people outside the formal sector. Physical and financial barriers to service access must be addressed if universal coverage is to become a reality.

Willingness to pay for voluntary health insurance in Tanzania

OBJECTIVE(S)

To assess how willing people would be to join a voluntary health insurance scheme and to see how they respond to changes in the benefit package. We also examined willingness to cross-subsidise the poor.

DESIGN

Cross-sectional study.

SUBJECTS

Two thousand two hundread and twenty four households comprising of 1,163 uninsured household heads asked about their willingness to pay for insurance in seven districts/councils (three urban and four rural) and 1,061 insured households were asked about their willingness to pay for insurance premiums for the poor in their community. Uninsured respondents were presented with two scenarios, the first reflected the current design of the Community Health Fund/Tiba Kwa Kadi (CHF/TIKA), the second offered expanded benefits, and included inpatient care in public facilities and transport.

RESULTS

Only 30% of uninsured rural households were willing to pay more than Tsh 5,000 the current premium level, their average amount was Tsh 10,741, while in urban areas one percent of households were willing to pay more than Tsh 5,000. There was very limited willingness to pay more than 5,000 Tsh, even with an expanded package in rural areas. Household from rural areas were more willing to cross-subsidise the poor, but contribution levels were higher in urban areas.

CONCLUSION

Communities need to be sensitised about the existence of the CHF/TIKA to encourage enrollment. Expanding the benefit package would further increase enrollment. However, few people would be willing to pay more than the current premium.

Comparison of costs of home and facility-based basic obstetric care in rural Bangladesh

This study compared the costs of providing antenatal, delivery and postnatal care in the home and in a basic obstetric facility in rural Bangladesh. The average costs were estimated by interviewing midwives and from institutional records. The main determinants of cost in each setting were also assessed. The cost of basic obstetric care in the home and in a facility was very similar, although care in the home was cheaper. Deliveries in the home took more time but this was offset by the capital costs associated with facility-based care. As use-rates increase, deliveries in a facility will become cheaper. Antenatal and postnatal care was much cheaper to provide in the facility than in the home. Facility-based delivery care is likely to be a cheaper and more feasible method for the care provider as demand rises. In settings where skilled attendance rates are very low, home-based care will be cheaper.

Utilization and management of maternal and child health funds in rural Nepal

Maternal and neonatal mortality rates are highest in the poorest countries, and financial barriers impede access to health care. Community loan funds can increase access to cash in rural areas, thereby reducing delays in care seeking. As part of a participatory intervention in rural Nepal, community women's groups initiated and managed local funds. We explore the factors affecting utilization and management of these funds and the role of the funds in the success of the women's group intervention. We conducted a qualitative study using focus group discussions, group interviews and unstructured observations. Funds may increase access to care for members of trusted 'insider' families adjudged as able to repay loans. Sustainability and sufficiency of funds was a concern but funds increased women's independence and enabled timely care seeking. Conversely, the perceived necessity to contribute may have deterred poorer women. While funds were integral to group success and increased women's autonomy, they may not be the most effective way of supporting the poorest, as the risk pool is too small to allow for repayment default.

A prospective key informant surveillance system to measure maternal mortality - findings from indigenous populations in Jharkhand and Orissa, India

Background

In places with poor vital registration, measurement of maternal mortality and monitoring the impact of interventions on maternal mortality is difficult and seldom undertaken. Mortality ratios are often estimated and policy decisions made without robust evidence. This paper presents a prospective key informant system to measure maternal mortality and the initial findings from the system.

Methods

In a population of 228 186, key informants identified all births and deaths to women of reproductive age, prospectively, over a period of 110 weeks. After birth verification, interviewers visited households six to eight weeks after delivery to collect information on the ante-partum, intra-partum and post-partum periods, as well as birth outcomes. For all deaths to women of reproductive age they ascertained whether they could be classified as maternal, pregnancy related or late maternal and if so, verbal autopsies were conducted.

Results

13 602 births were identified, with a crude birth rate of 28.2 per 1000 population (C.I. 27.7–28.6) and a maternal mortality ratio of 722 per 100 000 live births (C.I. 591–882) recorded. Maternal deaths comprised 29% of all deaths to women aged 15–49. Approximately a quarter of maternal deaths occurred ante-partum, a half intra-partum and a quarter post-partum. Haemorrhage was the commonest cause of all maternal deaths (25%), but causation varied between the ante-partum, intra-partum and post-partum periods. The cost of operating the surveillance system was US$386 a month, or US$0.02 per capita per year.

Conclusion

This low cost key informant surveillance system produced high, but plausible birth and death rates in this remote population in India. This method could be used to monitor trends in maternal mortality and to test the impact of interventions in large populations with poor vital registration and thus assist policy makers in making evidence-based decisions.

The economics of malaria in pregnancy--a review of the evidence and research priorities

Malaria in pregnancy is a major public-health problem in the developing world. However, on review of the evidence, we found its economic impact is not well documented. Adequately capturing the economic burden of malaria in pregnancy requires good epidemiological data including effects to the mother and baby, and better understanding of the long-term health and economic costs of malaria in pregnancy. We reviewed evidence on coverage, equity, cost, and cost-effectiveness of interventions to tackle malaria in pregnancy and found that although key interventions are highly cost effective, coverage is currently inadequate and fails to reach the poor. The evidence on interventions to improve treatment of malaria in pregnancy is scarce, and fails to adequately capture the benefits. There is also lack of data on cost-effectiveness of other interventions, especially outside of Africa, in low transmission settings, and for non-falciparum malaria. Research priorities on the economics of malaria in pregnancy are identified.

Maternal health in poor countries: the broader context and a call for action

In this paper, we take a broad perspective on maternal health and place it in its wider context. We draw attention to the economic and social vulnerability of pregnant women, and stress the importance of concomitant broader strategies, including poverty reduction and women's empowerment. We also consider outcomes beyond mortality, in particular, near-misses and long-term sequelae, and the implications of the close association between the mother, the fetus, and the child. We make links to a range of global survival initiatives, particularly neonatal health, HIV, and malaria, and to reproductive health. Finally, after examining the political and financial context, we call for action. The need for strategic vision, financial resources, human resources, and information are discussed.

Mobilising financial resources for maternal health

Coverage of cost-effective maternal health services remains poor due to insufficient supply and inadequate demand for these services among the poorest groups. Households pay too great a share of the costs of maternal health services, or do not seek care because they cannot afford the costs. Available evidence creates a strong case for removal of user fees and provision of universal coverage for pregnant women, particularly for delivery care. To be successful, governments must also replenish the income lost through the abolition of user fees. Where insurance schemes exist, maternal health care needs to be included in the benefits package, and careful design is needed to ensure uptake by the poorest people. Voucher schemes should be tested in low-income settings, and their costs and relative cost-effectiveness assessed. Further research is needed on methods to target financial assistance for transport and time costs. Current investment in maternal health is insufficient to meet the fifth Millennium Development Goal (MDG), and much greater resources are needed to scale up coverage of maternal health services and create demand. Existing global estimates are too crude to be of use for domestic planning, since resource requirements will vary; budgets need first to be developed at country-level. Donors need to increase financial contributions for maternal health in low-income countries to help fill the resource gap. Resource tracking at country and donor levels will help hold countries and donors to account for their commitments to achieving the maternal health MDG.

Equity in use of home-based or facility-based skilled obstetric care in rural Bangladesh: an observational study

BACKGROUND

Few studies have assessed whether the poorest people in developing countries benefit from giving birth at home rather than in a facility. We analysed whether socioeconomic status results in differences in the use of professional midwives at home and in a basic obstetric facility in a rural area of Bangladesh, where obstetric care was free of charge.

METHODS

We routinely obtained data from Matlab, Bangladesh between 1987 and 2001. We compared the benefits of home-based and facility-based obstetric care using a multinomial logistic and binomial log link regression, controlling for multiple confounders.

FINDINGS

Whether or not a midwife was used at home or in a facility differed significantly with wealth (adjusted odds ratio comparing the wealthiest and poorest quintiles 1.94 [95% CI 1.69-2.24] for home-based care, and 2.05 [1.72-2.43] for facility-based care). The gap between rich and poor widened after the introduction of facility-based care in 1996. The risk ratio (RR) between the wealthiest and poorest quintiles was 1.91 (adjusted RR 1.49 [95% CI 1.16-1.91] when most births with a midwife took place at home compared with 2.71 (1.66 [1.41-1.96]) at the peak of facility-based care.

INTERPRETATION

In this area of Bangladesh, a shift from home-based to facility-based basic obstetric care is feasible but might lead to increased inequities in access to health care. However, there is also evidence of substantial inequities in home births. Before developing countries reinforce home-based births with a skilled attendant, research is needed to compare the feasibility, cost, effectiveness, acceptability, and implications for health-care equity in both approaches.

Costs of near-miss obstetric complications for women and their families in Benin and Ghana

This paper estimates the total cost to women and their families associated with a spontaneous vaginal delivery and five types of 'near-miss' obstetric complication in Benin and Ghana, and assesses affordability in relation to household cash expenditure. A retrospective evaluation of costs was carried out among 121 mothers in three hospitals in Ghana. A prospective evaluation of costs was undertaken among 420 pregnant women in two hospitals in Benin. Information was collected on the cost of travel to the facilities and of direct medical and non-medical costs incurred during their stay in hospital. In Benin, costs ranged from an average of 15 US dollars for a spontaneous delivery to 256 US dollars for a near-miss complication caused by dystocia. In Ghana, average costs ranged from 18 US dollars for a spontaneous vaginal delivery to 115 US dollars for a near-miss complication caused by haemorrhage. Medical costs accounted for the largest share of total costs, mainly drugs and medical supplies in Ghana and costs of the delivery and any surgical intervention in Benin. Payments associated with a spontaneous vaginal delivery amounted to at least 2% of annual household cash expenditure in both countries. In the case of severe obstetric complications, costs incurred reached a high of 34% of annual household cash expenditure in Benin. The economic burden of hospital-based delivery care in Ghana and Benin is likely to deter or delay women's use of health services. Should a woman develop severe obstetric complications while in labour, the relatively high costs of hospital care could have a potentially catastrophic impact on the household budget.

Is hygiene promotion cost-effective? A case study in Burkina Faso

OBJECTIVES

To estimate the incremental cost-effectiveness of a large-scale urban hygiene promotion programme in terms of reducing the incidence of childhood diarrhoeal disease in Bobo-Dioulasso, Burkina Faso.

METHODS

Total and incremental costs of the programme were estimated retrospectively from the perspectives of the provider, from the households who change their behaviour as a result of the programme and from society (the sum of the two). The programme effects were derived from an intervention study that estimated the impact on handwashing with soap after handling child stools through a time-series method of observing 37 319 mothers. Using data from the literature, the associated reductions in childhood morbidity and mortality were estimated. The direct medical savings and indirect savings of caregiver time and lost productivity associated with child death were estimated from interviews with households and health workers. The cost and outcome data were combined to provide an estimate of the cost per mother who starts handwashing with soap as a result of the programme and the cost per case of childhood diarrhoea averted.

RESULTS

The total provider cost (including start-up and 3-year running costs) was $302 507. Core programme activities accounted for 31% of the cost, administration 40%. The total cost to the 7286 households associated with changing behaviour during the 3 years of programme implementation was $160 125 ($7.3 per year per household). An estimated 8638 cases of diarrhoea, 864 outpatient consultations, 324 hospital referrals and 105 deaths were averted by the programme during this time. Savings to the provider from reduced treatment costs were estimated at $10 716 and savings to the households from averted treatment cost were $9136, resulting in a total saving to society of $19 852, increasing to $393 967 if indirect savings are included. The incremental provider cost per case of diarrhoea averted was $33.8. The incremental cost to society was $51.3 falling to $7.9 if indirect savings are included. If the programme were to be replicated elsewhere, savings in the international research input and start-up costs could reduce provider costs to $26.9 per case of diarrhoea averted. The annual cost of the programme represents 0.001% of the national health budget for Burkina Faso. The direct annual cost of implementing the programme at the household level represents 1.3% of annual household income.

CONCLUSION

Hygiene promotion reduces the occurrence of childhood diarrhoea in Burkina Faso at less than 1% of the Ministry of Health budget and less than 2% of the household budget, and could be widely replicated at lower cost.

Economic impact of using mirtazapine compared to amitriptyline and fluoxetine in the treatment of moderate and severe depression in the UK

This study modelled the economic impact of mirtazapine, compared to amitriptyline and fluoxetine, in the management of moderate and severe depression in the UK, as well as the costs related to discontinuation of antidepressant treatment. Decision models of the management of moderate and severe depression were developed from clinical trial data, resource use obtained from interviews with general practitioners and psychiatrists, and published literature, and were used to estimate the expected direct National Health Service (NHS) costs of managing a patient with moderate or severe depression. The expected cost of healthcare resource use attributable to managing a patient suffering from moderate or severe depression who discontinues antidepressant treatment, irrespective of the initial treatment, was estimated to be pounds sterling 206 (range pounds sterling 50 to pounds sterling 504) over five months. Using mirtazapine instead of amitriptyline for seven months increases the proportion of successfully treated patients by 21% (from 19.2 to 23.2%) and reduces the expected direct NHS cost by pounds sterling 35 per patient (from pounds sterling 448 to pounds sterling 413). Using mirtazapine instead of fluoxetine for six months increases the proportion of successfully treated patients by 22% (from 15.6 to 19.1%), albeit for an additional cost to the NHS of pounds sterling 27 per patient (from pounds sterling 394 to pounds sterling 420). In conclusion, this study suggests that mirtazapine is a cost-effective antidepressant compared to amitriptyline and fluoxetine in the management of moderate and severe depression in the UK.
