A recent systematic review identified few papers on the economic evaluation of systems for emergency transport of acutely ill or injured patients. In addition, we found no articles dealing with the methodological challenges posed by such studies in low-income or middle-income countries. We therefore carried out an analysis of issues that are of particular salience to this important topic. This is an intellectual study in which we develop models, identify their limitations, suggest potential extensions to the models and discuss priorities for empirical studies to populate models. First, we develop a general model to calculate changes in survival contingent on the reduced time to treatment that an emergency transport system is designed to achieve. Second, we develop a model to estimate transfer times over an area that will be served by a proposed transfer system. Third, we discuss difficulties in obtaining parameters with which to populate the models. Fourth, we discuss costs, both direct and indirect, of an emergency transfer service. Fifth, we discuss the issue that outcomes other than survival should be considered and that the effects of a service are a weighted sum over all the conditions and severities for which the service caters. Lastly, based on the above work, we identify priorities for research. To our knowledge, this is the first study to identify and frame issues in the health economics of acute transfer systems and to develop models to calculate survival rates from basic parameters, such as time delay/survival relationships, that vary by intervention type and context.

Previous empirical studies on the effects of foreign aid on economic growth have generated mixed results that make it difficult to draw policy recommendations. The main reason for such mixed results is the choice of a single aggregate list of countries, regardless of the disparities in levels of development. This study therefore fills the development gap by disaggregating the African data into a panel of 20 middle- income and 19 low- income African countries over a period of 15 years between 1995 and 2010, and employing a dynamic generalized method of moments (GMM) model to address the dynamic nature of economic growth as well as the problems of endogeneity. The results of this study support the theoretical hypothesis that a positive relationship between aid and GDP growth exists, but only for low-income African countries, not middle-income ones. On the other hand, the study reveals that middle- income African countries tend to experience a greater impact on their economic growth from foreign direct investment (FDI) and natural resources revenues, mainly oil exports. This implies that the frequent criticism that foreign aid has not contributed to economic growth is flawed, at least in the case of low-income African countries. In fact, foreign aid has played a critical role in stimulating economic growth in such countries through supplementing domestic sources of finance such as savings, thus increasing the amount of investment and capital stock in them.

Hypertension in low-income and middle-income countries (LMICs) is largely undiagnosed and uncontrolled, representing an untapped opportunity for public health improvement. Implementation of hypertension control strategies in low-resource settings depends in large part on cost considerations. However, evidence on the cost-effectiveness of hypertension interventions in LMICs is varied across geographical, clinical and evaluation contexts. We conducted a comprehensive search for published economic evaluations of hypertension treatment programmes in LMICs. The search identified 71 articles assessing a wide range of hypertension intervention designs and cost components, of which 42 studies across 15 countries reported estimates of cost-effectiveness. Although comparability of results was limited due to heterogeneity in the interventions assessed, populations studied, costs and study quality score, most interventions that reported cost per averted disability-adjusted life-year (DALY) were cost-effective, with costs per averted DALY not exceeding national income thresholds. Programme elements that may reduce cost-effectiveness included screening for hypertension at younger ages, addressing prehypertension, or treating patients at lower cardiovascular disease risk. Cost-effectiveness analysis could provide the evidence base to guide the initiation and development of hypertension programmes.

BackgroundNo systematic attempt has been made to calculate the costs of scaling up mental health services in low-and middle-income countries.AimsTo estimate the expenditures needed to scale up the delivery of an essential mental healthcare package over a 10-year period (2006–2015).MethodA core package was defined, comprising pharmacological and/or psychosocial treatment of schizophrenia, bipolar disorder, depression and hazardous alcohol use. Current service levels in 12 selected low-and middle-income countries were established using the WHO–AIMS assessment tool. Target-level resource needs were derived from published need assessments and economic evaluations.ResultsThe cost per capita of providing the core package attarget coverage levels (in US dollars) ranged from $1.85 to $2.60 per year in low-income countries and $3.20 to $6.25 per year in lower-middle-income countries, an additional annual investment of $0.18–0.55 per capita.ConclusionsAlthough significant new resources need to be invested, the absolute amount is not large when considered at the population level and against other health investment strategies.

IntroductionHealth systems responsiveness is a key objective of any health system, yet it is the least studied of all objectives particularly in low-income and middle-income countries. Research on health systems responsiveness highlights its multiple elements, for example, dignity and confidentiality. Little is known, however, about underlying theories of health systems responsiveness, and the mechanisms through which responsiveness works. This realist synthesis contributes to bridging these two knowledge gaps.Methods and analysisIn this realist synthesis, we will use a four-step process, comprising: mapping of theoretical bases, formulation of programme theories, theory refinement and testing of programme theories using literature and empirical data from Ghana and Vietnam. We will include theoretical and conceptual pieces, reviews, empirical studies and grey literature, alongside the primary data. We will explore responsiveness as entailing external and internal interactions within health systems. The search strategy will be purposive and iterative, with continuous screening and refinement of theories. Data extraction will be combined with quality appraisal, using appropriate tools. Each fragment of evidence will be appraised as it is being extracted, for its relevance to the emerging programme theories and methodological rigour. The extracted data pertaining to contexts, mechanisms and outcomes will be synthesised to identify patterns and contradictions. Results will be reported using narrative explanations, following established guidance on realist syntheses.Ethics and disseminationEthics approvals for the wider RESPONSE (Improving health systems responsiveness to neglected health needs of vulnerable groups in Ghana and Vietnam) study, of which this review is one part, were obtained from the ethics committees of the following institutions: London School of Hygiene and Tropical Medicine (ref: 22981), University of Leeds, School of Medicine (ref: MREC19-051), Ghana Health Service (ref: GHS-ERC 012/03/20) and Hanoi University of Public Health (ref: 020-149/DD-YTCC).We will disseminate results through academic papers, conference presentations and stakeholder workshops in Ghana and Vietnam.PROSPERO registration numberCRD42020200353.

Global emphasis has shifted beyond reducing child survival rates to improving health and developmental trajectories in childhood. Optimum early childhood experience is believed to allow children to benefit fully from educational opportunities resulting in improved human capital. Investment in early childhood initiatives in low-income and middle-income countries (LMICs) is increasing. These initiatives use early childhood developmental assessment tools (CDATs) as outcome measures. CDATs are also key measures in the evaluation of programmatic health initiatives in LMICs, influencing public health policy. Interpretation of CDAT outcomes requires understanding of their structure and psychometric properties. This article reviews the structure and main methods of CDAT development with specific considerations when applied in LMICs.
