Abstract
RATIONALE Studies suggest that increased breastfeeding rates can provide substantial financial savings, but the scale of such savings in the UK is not known. OBJECTIVE To calculate potential cost savings attributable to increases in breastfeeding rates from the National Health Service perspective. DESIGN AND SETTINGS Cost savings focussed on where evidence of health benefit is strongest: reductions in gastrointestinal and lower respiratory tract infections, acute otitis media in infants, necrotising enterocolitis in preterm babies and breast cancer (BC) in women. Savings were estimated using a seven-step framework in which an incidence-based disease model determined the number of cases that could have been avoided if breastfeeding rates were increased. Point estimates of cost savings were subject to a deterministic sensitivity analysis. RESULTS Treating the four acute diseases in children costs the UK at least £89 million annually. The 2009-2010 value of lifetime costs of treating maternal BC is estimated at £959 million. Supporting mothers who are exclusively breast feeding at 1 week to continue breast feeding until 4 months can be expected to reduce the incidence of three childhood infectious diseases and save at least £11 million annually. Doubling the proportion of mothers currently breast feeding for 7-18 months in their lifetime is likely to reduce the incidence of maternal BC and save at least £31 million at 2009-2010 value. CONCLUSIONS The economic impact of low breastfeeding rates is substantial. Investing in services that support women who want to breast feed for longer is potentially cost saving.

Abstract
The increasing use of willingness to pay (WTP) to value the benefits of malaria control interventions offers a unique opportunity to explore the possibility of estimating a transferable indicator of mean WTP as well as studying differences across studies. As regression estimates from individual WTP studies are often assumed to transfer across populations it also provides an opportunity to question this practice. Using a qualitative review and meta analytic methods, this article determines what has been studied and how, provides a summary mean WTP by type of intervention, considers how and why WTP estimates vary and advises on future reporting of WTP studies. WTP has been elicited mostly for insecticide-treated nets, followed by drugs for treatment. Mean WTP, including zeros, is US$2.79 for insecticide-treated nets, US$6.65 for treatment and US$2.60 for other preventive services. Controlling for a limited number of sample and design effects, results can be transferred to different countries using the value function. The main concerns are the need to account for a broader range of explanators that are study specific and the ability to transfer results into malaria contexts beyond those represented by the data. Future studies need to improve the reporting of WTP.

Abstract
Sensitivity analysis allows analysts to explore the impact of uncertainty on their findings. It is an important part of any economic evaluation, and a lack of analysis is evidence of a poor quality study. Sensitivity analysis helps the analyst evaluate the reliability of conclusions for the context of the evaluation and can also facilitate consideration of the generalizability of results to other settings. The variety of one and multi-way sensitivity analyses offer simple and complementary approaches to evaluating the impact of uncertainty on the results and conclusions of economic evaluations. The paper begins with a brief discussion of the types of uncertainty that can arise in economic evaluation, and follows with suggestions of how to plan a justified sensitivity analysis. A number of specific techniques are worked through with examples, followed by a discussion of when it is best to use them. The main weakness associated with sensitivity analysis is the control that the analyst retains over three parts of the process: the choice of which variables to vary and which to treat as known or fixed; the amount of variation around the base value of the parameter that is considered clinically meaningful or policy-relevant; and the determination of what constitutes a sensitive or robust finding. It is therefore essential that the approach of the analyst is clear and justified. It is likely that the future will see further developments in the approaches and training of statistical analysis. But in the meantime, an increase in the number of evaluators undertaking a wider range of sensitivity analysis would improve the quality of evidence for, and outcomes of, decision-making.

Abstract
BACKGROUND We undertook a multicentre randomised controlled trial that compared the standard model of antenatal care with a new model that emphasises actions known to be effective in improving maternal or neonatal outcomes and has fewer clinic visits. METHODS Clinics in Argentina, Cuba, Saudi Arabia, and Thailand were randomly allocated to provide either the new model (27 clinics) or the standard model currently in use (26 clinics). All women presenting for antenatal care at these clinics over an average of 18 months were enrolled. Women enrolled in clinics offering the new model were classified on the basis of history of obstetric and clinical conditions. Those who did not require further specific assessment or treatment were offered the basic component of the new model, and those deemed at higher risk received the usual care for their conditions; however, all were included in the new-model group for the analyses, which were by intention to treat. The primary outcomes were low birthweight (<2500 g), pre-eclampsia/eclampsia, severe postpartum anaemia (<90 g/L haemoglobin), and treated urinary-tract infection. There was an assessment of quality of care and an economic evaluation. FINDINGS Women attending clinics assigned the new model (n=12568) had a median of five visits compared with eight within the standard model (n=11958). More women in the new model than in the standard model were referred to higher levels of care (13.4% vs 7.3%), but rates of hospital admission, diagnosis, and length of stay were similar. The groups had similar rates of low birthweight (new model 7.68% vs standard model 7.14%; stratified rate difference 0.96 [95% CI -0.01 to 1.92]), postpartum anaemia (7.59% vs 8.67%; 0.32), and urinary-tract infection (5.95% vs 7.41%; -0.42 [-1.65 to 0.80]). For pre-eclampsia/eclampsia the rate was slightly higher in the new model (1.69% vs 1.38%; 0.21 [-0.25 to 0.67]). Adjustment by several confounding variables did not modify this pattern. There were negligible differences between groups for several secondary outcomes. Women and providers in both groups were, in general, satisfied with the care received, although some women assigned the new model expressed concern about the timing of visits. There was no cost increase, and in some settings the new model decreased cost. INTERPRETATIONS Provision of routine antenatal care by the new model seems not to affect maternal and perinatal outcomes. It could be implemented without major resistance from women and providers and may reduce cost.

Abstract
Short-run economic consequences of 'malaria' on households were examined in a household survey in Matale, a malaria-endemic district of Sri Lanka. On average a household incurred a total cost of Rs 318 (US$ 7) per patient who fully recovered from 'malaria'. 24% of this was direct cost, 44% indirect cost for the patient and 32% indirect cost for the household. Direct costs were greater for those seeking treatment in the private sector. Notably a large proportion of direct costs was spent on complementary goods such as vitamins and foods considered to be nutritional. Indirect cost was measured and valued on the basis of output/ income losses incurred at the household level rather than using a general indicator such as average wage rate. Loss of output and wages accounted for the highest proportion of the indirect cost of the patients as well as the households. Relative to children, more young adults and middle-aged people had 'malaria' which also caused greater economic loss in these age groups. Women tended to care for patients rather than substitute their labour to cover productive work lost due to illness. We compare the methods used by other researchers for valuing indirect cost, demonstrating the significant impact that methods of measurement and valuation can have on the estimation of indirect cost, and justify the recommendation for methodological research in this area.

Abstract
It was estimated that in 1990, major parasitic diseases accounted for 11.7% of the disease burden from communicable disease. As advances in the prevention, diagnosis and treatment of parasitic diseases are made and implemented, there is a growing economic literature to help decision-makers choose the most efficient control method. The aim of this paper is to identify, describe and analyse the available published data on the efficiency of control strategies against parasitic diseases. Internal validity is assessed through the quality of economic evaluations over time using a series of standard questions, and external validity is assessed in terms of the potential to extrapolate results to other settings. This leads to a discussion of the legitimacy and feasibility of pooling data or results from studies for priority setting in the health sector, resulting in three recommendations: to increase the coverage of economic evaluations for parasitic diseases and types of interventions; to improve the internal validity of studies through guidelines and review procedures; and to explore the external validity of research results by examining their predictive validity across settings.

Abstract
The WHO is testing a new rationalised programme of antenatal care in a multicentre randomised trial. The motivation for this trial arose from the current uncertainty about the effectiveness of different approaches to provision of routine antenatal care. Decision makers also lack information about the costs of providing routine antenatal care and the cost-effectiveness of one programme over another. Such information will be needed before the final choice of programme can be made. The WHO trial provides an ideal opportunity to estimate and compare the incremental costs and cost-effectiveness of the new programme in four countries (Argentina, Cuba, Saudi Arabia, Thailand). A separate economic component has been organised to measure the costs of antenatal care. Methods for cost identification and measurement, and methods for economic analysis in the context of an international study are based on current recommendations for the conduct of economic evaluations alongside trials. However, several aspects require further development. In particular, this includes defining standard methods for costing in different countries; measuring women's costs of access to care; and making comparisons across international settings. The economic evaluation will also inform similar multicentre international trials and investigate issues of generalisability beyond trial settings.

Abstract
The health-related quality of life (HRQoL) literature presents a confused picture of what 'equivalence' in the cross-cultural use of HRQoL questionnaires means and how it can be assessed. Much of this confusion can be attributed to the 'absolutist' approach to the cross-cultural adaptation of HRQoL questionnaires. The purpose of this paper is to provide a model of equivalence from a universalist perspective and to link this to the translation and adaptation of HRQoL questionnaires. The model evolved from reviews of the HRQoL and other literatures, interviews and discussions with researchers working in HRQoL and related areas and practical experience in the adaptation and development of HRQoL instruments. The model incorporates six key types of equivalence. For each type of equivalence the paper provides a definition, proposes various strategies for examining whether and how types of equivalence can be achieved, illustrates the relationships between them and suggests the order in which they should be tested. The principal conclusions are: (1) that a universalist approach to the cross-cultural adaptation of HRQoL instruments requires that six types of equivalence be taken into account; (2) that these are sufficient to describe and explain the nature of the cross-cultural adaptation process; (3) that this approach requires careful qualitative research in target cultures, particularly in the assessment of conceptual equivalence; and (4) that this qualitative work will provide information which will be fundamental in deciding whether to adapt an existing instrument and which instrument to adapt. It should also result in a more sensitive adaptation of existing instruments and provide valuable information for interpreting the results obtained using HRQoL instruments in the target culture.

Abstract
OBJECTIVE To calculate the costs at Kilifi District Hospital (KDH) and Malindi Sub-district Hospital (MSH) of treating paediatric malaria admissions including three common presentations of severe paediatric malaria, i.e. cerebral malaria, severe malaria anaemia and malaria-associated seizures; and to estimate the implications for hospital expenditure of a reduction in paediatric malaria admissions. METHODS Patient data were obtained from hospital records. All costs were allocated to departments that provided direct patient care by a four-stage step-down procedure. Laboratory and drug costs of treating paediatric malaria admissions were separately identified. RESULT Unit recurrent costs per admission in KDH ranged from US $57 for 'other' paediatric malaria to US $105 for cerebral malaria, and in MSH from US $33 to US $44 for the same categories. The annual recurrent cost of treating all paediatric malaria admissions to KDH prior to the trial was estimated at US $78 900. Adjusting for preintervention differences in malaria admission rates and age between intervention and control areas, the ITBN trial found a 41% reduction in paediatric malaria admissions. The reduction in admissions resulted in an estimated saving of US $6240 in the cost of treating paediatric malaria admissions from the intervention area. CONCLUSION There would be a substantial reduction in costs of treating paediatric malaria admissions if the intervention were introduced in the whole catchment area of the hospital. Actual savings would depend on the proportion of potential savings that can in practice be realised, and on the effectiveness of the intervention when routinely implemented.

Abstract
Clinical trials have indicated that treating mosquito nets with insecticide could be a potentially cost-effective method of preventing malaria. As malaria is one of the most common causes of death in children under five in developing countries, there has been substantial interest in whether such findings can be replicated for a country's control programme in practice. The cost-effectiveness of the Gambian National Insecticide-impregnated Bednet Programme (NIBP), from the viewpoint of providers (government and non-governmental agencies) and the community, has been calculated. Information was collected from existing records, interviews with NIBP personnel, observation and household surveys. Information is provided on the resource use consequences of the NIBP in terms of reduced expenditure on anti-malaria preventive measures, treatment in government health services, household financed treatment and "charity" (burial, funeral and mourning activities), as well as cash income lost as a result of child death. The annual implementation cost of the NIBP was D757,875 (US$91,864), of which 86% was recurrent cost. The estimated number of death averted was 40.56. The net implementation cost-effectiveness ratio per death averted and discounted life years gained were D3884 (US$471) and D260 (US$31.5), respectively. Adding the cost of all mosquito nets would increase the cost-effectiveness ratios by over five times, which is an important consideration for countries with a lower coverage of mosquito nets per capita. It is concluded that insecticide-impregnated mosquito nets are one of the more efficient ways of reducing deaths in children under 10 years in rural Gambia.

Abstract
Information on hospital costs is urgently needed in planning, budgeting, and hospital-based efficiency evaluations. The aim of this study was to estimate and compare the total and unit costs of providing care in Kilifi District hospital (KDH) and Malindi Sub-district Hospital (MSH). However, the specific objectives were: calculate the annual total cost of providing care in KDH and MSH; compare the unit costs for KDH with those of MSH; and demonstrate hospital costing methodology. The step-down procedure was used to apportion general costs to departments that provided direct patient care, i.e the wards and outpatient department. Results indicated that the Kenyan Government spent about Ksh 49.4 million and Kshs.22.7 million during the financial year 1993/94 on eh KDH and MSH, respectively. In KDH, the paediatrics ward absorbs the greatest proportion of inpatient department's share of the total cost; whereas, in MSH it is the maternity ward that consumes the greatest proportion. The KDH is more expensive than MSH even in terms of unit costs. For example, the cost per admission was Kshs.5,055 in KDH an dKshs.2,088 in MSH; cost per inpatient day was Kshs.445 in KDH and Kshs.365 in MSH; cost per bed was Kshs.119,590 in KDH and Kshs.112.064 in MSH; and cost per visit was Ksh.206 in KDH and kshs.118 in MSH. However it is likely that the level and quality of service provided between the two hospitals also differ. The public hospitals absorb a substantial proportion of the recurrent budget, so it is imperative that resource use and the role of the role (as district referral facility) in the district health system should be monitored and evaluated regularly.

Abstract
The increasing use of health-related quality of life (HRQOL) questionnaires in multinational studies has resulted in the translation of many existing measures. Guidelines for translation have been published, and there has been some discussion of how to achieve and assess equivalence between source and target questionnaires. Our reading in this area had led us, however, to the conclusion that different types of equivalence were not clearly defined, and that a theoretical framework for equivalence was lacking. To confirm this we reviewed definitions of equivalence in the HRQOL literature on the use of generic questionnaires in multicultural settings. The literature review revealed: definitions of 19 different types of equivalence; vague or conflicting definitions, particularly in the case of conceptual equivalence; and the use of many redundant terms. We discuss these findings in the light of a framework adapted from cross-cultural psychology for describing three different orientations to cross-cultural research: absolutism, universalism and relativism. We suggest that the HRQOL field has generally adopted an absolutist approach and that this may account for some of the confusion in this area. We conclude by suggesting that there is an urgent need for a standardized terminology within the HRQOL field, by offering a standard definition of conceptual equivalence, and by suggesting that the adoption of a universalist orientation would require substantial changes to guidelines and more empirical work on the conceptualization of HRQOL in different cultures.

Abstract
Urban hospital outpatient clinics in developing countries are said to be overburdened and some policy experts are proposing a new intermediate tier of advanced health centres between hospitals and health centres to solve this problem (termed 'reference centres' by the World Health Organization). In Maseru, Lesotho, hospital congestion led the Ministry of Health to decide to build reference centres. To delineate precisely how these centres should operate, research was carried out on the existing system comparing utilization, quality and cost between health centre and hospital outpatient care. The study showed that throughout per clinician at the hospital and the city health centres was similar; that the hospital service saw a greater proportion of adults and more men; that the technical care quality was similar; and, that health centre staff took longer with patients and had higher interpersonal consultation scores. Average costs at the hospital were 39 per cent greater, but, the calculated net costs to the provider at the hospital and at government centres were very similar once user fees had been taken into account. The results questioned the assumptions underlying the decision to build reference centres in Maseru, and also the relevance of a new tier to solve health service delivery problems in the city. The study highlights the need for national and municipal planners to examine carefully existing health services with respect to utilization, quality and cost before adopting urban reference centres as a standard solution to congested hospitals.

Abstract
The recent enthusiasm for impregnated bednets as a malaria control measure leaves unresolved the question of how to finance them. The National Impregnated Bednet Programme in The Gambia faced the question of how to obtain funds from villages to finance the cost of insecticide, but knew very little about current village fundraising for development purposes. A survey was conducted of such fundraising, and questions also asked about willingness to pay for insecticide and preferred means of paying. All 53 villages surveyed paid taxes/rates, but 34% of villages reported no voluntary fundraising. The most common reason for collecting money was for the maintenance of wells (40% of villages). Collective farming was used as a means of raising money in 32% of villages. There was some variation in the type and extent of fundraising by region and also by the predominant ethnic groups of the village. Villages with voluntary fundraising activities seemed to have well established collective mechanisms for agreeing on sums to be collected and their use, and for collecting and recording income and expenditure. Non-payment was rare, and misuse of funds was not reported. Respondents were asked how much compounds might be willing to pay for insecticide impregnantion: the most frequently cited maximum amounts were D5 and 10, and minimum D1 and 5 (D15 = 1 pound). The paper discusses payment options for insecticide, such as whether the village should be allowed to decide itself how to raise funds, and whether the payment should be made only by households with nets or by a village-wide mechanism such as collective farming.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
This paper reviews the guidelines and recommendations propounded by Morrison and Gyldmark in relation to the use of contingent valuation (CV) to value health states. The issues raised are: that QALYs may not be sufficiently sensitive to changes in health thus requiring the use of CV formulation; the questionable practice of reinterpreting monetary values; and the possibility of income bias. It is concluded that further empirical research, at least, is needed to verify whether this approach should be rejected in favour of quality adjusted life years (QALYs) or healthy year equivalents (HYEs).
