Supporting local ownership of transition processes
Globally, an increasing number of countries have made progress towards HIV epidemic control, yet decreasing donor funding and insufficient domestic investments threaten these strides. Within this context, the global community is interested in how to successfully transition responsibility for HIV services from donor-funded programmes to local ownership within the broader healthcare system. This analysis explores how to centre local leadership in t…
Estimating the opportunity cost of seasonal malaria chemoprevention implementation in Burkina Faso, Mali and Senegal
Background Seasonal malaria chemoprevention (SMC) is a widely implemented malaria prevention strategy for children under five in the Sahel and sub-Sahel regions of Africa. This study aimed to estimate the full opportunity costs associated with SMC implementation in Mali, Burkina Faso and Senegal, addressing a gap in existing research that often focused solely on health system costs. Using a repeated descriptive cross-sectional design, data were c…
The cost of mass drug administration for trachoma in two counties of the Republic of South Sudan
Community-wide distribution of azithromycin, otherwise known as mass drug administration (MDA), is a component of the World Health Organization-endorsed SAFE strategy for the elimination of trachoma as a public health problem. In the Republic of South Sudan, 2.9 million people are known to live in areas that are known to require interventions and warrant MDA. This study estimated the total costs and cost per person treated during MDA in two count…
An assessment of primary health care costs and resource requirements in Kaduna and Kano, Nigeria
Introduction: The availability of quality primary health care (PHC) services in Nigeria is limited. The PHC system faces significant challenges and the improvement and expansion of PHC services is constrained by low government spending on health, especially on PHC. Out-of-pocket (OOP) expenditures dominate health spending in Nigeria and the reliance on OOP payments leads to financial burdens on the poorest and most vulnerable populations. To addr…
Costs and resource needs for primary health care in Ethiopia
Introduction: The Government of Ethiopia (GoE) has made significant progress in expanding access to primary health care (PHC) over the past 15 years. However, achieving national PHC targets for universal health coverage will require a significant increase in PHC financing. The purpose of this study was to generate cost evidence and provide recommendations to improve PHC efficiency. Methods: We used the open access Primary Health Care Costing, Ana…
The costs and financing needs of delivering Kenya’s primary health care service package
Introduction: For many Kenyans, high-quality primary health care (PHC) services remain unavailable, inaccessible, or unaffordable. To address these challenges, the Government of Kenya has committed to strengthening the country's PHC system by introducing a comprehensive package of PHC services and promoting the efficient use of existing resources through its primary care network approach. Our study estimated the costs of delivering PHC services i…
Conducting Benefit-Cost Analysis in Low- and Middle-Income Countries
Investing in global health and development requires making difficult choices about what policies to pursue and what level of resources to devote to different initiatives. Methods of economic evaluation are well established and widely used to quantify and compare the impacts of alternative investments. However, if not well conducted and clearly reported, these evaluations can lead to erroneous conclusions. Differences in analytic methods and assum…
The effect of costs on Kenyan households’ demand for medical care
In an environment of constrained resources, policymakers must identify solutions for financing and delivering health services that are efficient and sustainable. However, such solutions require that policymakers understand the complex interaction between household utilization patterns, factors influencing household medical decisions, and provider performance. This study examined whether and under what conditions out-of-pocket, transportation, and…
Malaria prevention measures in Burkina Faso
Most of the households received bed nets and other preventive method for free. There is equity in expenditures across SES groups. Free distribution of ITNs ensured that there was equity in ITN ownership among households. More research on the possibility of increasing access to other locally relevant methods of malaria control that proved to be effective is need

Cost-effectiveness of community-based management of acute malnutrition in Malawi
This study assessed the cost-effectiveness of community-based management of acute malnutrition (CMAM) to prevent deaths due to severe acute malnutrition among children under-five. The analysis used a decision tree model to compare the costs and effects of two options to treat severe acute malnutrition: existing health services with CMAM vs existing health services without CMAM. The model used outcome and cost data from a CMAM programme in Dowa di…
Comparison of trust in public vs private health care providers in rural Cambodia
How trust in providers affects health care-seeking behaviour is not well understood. Focus groups and household surveys were conducted in Cambodia to examine how villagers describe their trust in public and private providers, and to assess whether a difference exists in provider trust levels. Our findings suggest the reasons for trusting public and private providers differ, and that villagers' trust in and relationship with providers is one of th…

Health System Costs of Menstrual Regulation and Care For Abortion Complications in Bangladesh
CONTEXT: Treatment of complications of unsafe abortion can be a significant financial drain on health system resources, particularly in developing countries. In Bangladesh, menstrual regulation is provided by the government as a backup to contraception. The comparison of economic costs of providing menstrual regulation care with those of providing treatment of abortion complications has implications for policy in Bangladesh and internationally. M…

Poverty and Access to Health Care in Developing Countries
People in poor countries tend to have less access to health services than those in better‐off countries, and within countries, the poor have less access to health services. This article documents disparities in access to health services in low‐ and middle‐income countries (LMICs), using a framework incorporating quality, geographic accessibility, availability, financial accessibility, and acceptability of services. Whereas the poor in LMICs are c…

Cost and cost-effectiveness of HIV/Aids prevention strategies in developing countries
Many donors and countries are striving to respond to the HIV/AIDS epidemic by implementing prevention programmes. However, the resources available for providing these activities relative to needs are limited. Hence, decision-makers must choose among various types of interventions. Cost information, both measures of cost and cost-effectiveness, serves as a critical input into the processes of setting priorities and allocating resources efficiently…
Allowing for differential timing in cost analyses
There are differences in timing related to when costs of certain inputs are incurred and when they are used over the lifetime of a programme. This paper looks at the issues related to the comparison of cost data over time focusing on discounting and annualization adjustments, which are used by economists to calculate financial and economic costs. The process of discounting is used to deal with the notion of time preference. Time preference implie…
The quality of care by private practitioners for sexually transmitted diseases in Uganda
One of the limited number of strategies available to reduce the spread of human immunodeficiency virus (HIV) infections in sub-Saharan Africa is the effective treatment of other, curable, sexually transmitted diseases (STDs). At present, a large proportion of people with STDs either treat themselves at home or seek treatment from private sector practitioners (PSPs) rather than use publicly funded services. A randomized controlled trial of the eff…
Cost and cost-effectiveness guidelines
Given the increased awareness of the importance of cost-effectiveness in health care, there has been a growth in the number of published economic evaluations in recent years. Partly in response to concerns about deficiencies in the methodology of published studies, there has been a growth of interest in guidelines for economic evaluation. This paper reviews the various objectives of economic analyses, and then summarizes the existing groups of gu…
Allowing for uncertainty in economic evaluations
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 sensiti…
