  • Evaluating global health programmes targeting under-5 mortality

    Open AccessAvi Kenny, Mark J Siedner et al.ARTICLEBMJ Global Health2026

    Reducing the under-5 mortality rate (U5MR) is a key public health priority and remains a persistent challenge in low- and middle-income countries. Many interventions have been developed in attempts to lower U5MR through partnerships between governments, funding partners, researchers, product developers and non-governmental organisations. The well-intentioned desire to use data to set priorities has led to many large-scale evaluations that specify…

  • Using country-level variables to discover country clusters beyond traditional health policy and performance metrics

    Open AccessZoïe W Alexiou, Siddharth Dixit et al.ARTICLEPLOS Global Public Health2025

    HIV remains a major public health challenge, with 1.4 million new infections and 31.6 million people accessing antiretroviral treatment in 2024. In many countries, HIV services have been provided through vertical programs, which, although highly successful in bringing treatment to people living with HIV since the early 2000s, are unlikely to sustain progress beyond donor dependency. The increasing push towards Universal Health Coverage (UHC), whi…

    Sauti ya Vijana (SYV) is a ten-session, group-based mental health and life skills intervention targeting young people living with HIV (YPLWH) in Tanzania. By addressing mental health distress and promoting self-efficacy and resilience to HIV-related stigma and disclosure, SYV aims to improve adherence to antiretroviral therapy (ART) and virologic suppression. A pilot randomized controlled trial (RCT) of SYV was conducted in Moshi, Tanzania, from …

  • Recruitment and engagement of a cohort of women living with HIV in Nigeria

    Open AccessNwamaka Alexandra Ezeonu, John O Olawepo et al.ARTICLEPLOS Global Public Health2025

    Nigeria has a high burden of mother to child transmission (MTCT) of HIV. There is paucity of large-scale prospective cohort studies to provide insight into the reasons for the abysmal MTCT indices. This paper describes the baseline characteristics of women living with HIV who signed consent to participate in future clinical or implementation trials. The Nigeria Implementation Science Alliance (NISA) developed an open multicentre prospective cohor…

  • Global Disparities in Premature Mortality

    Open AccessØ Karlsson, D T Jamison et al.ARTICLEJAMA Health Forum2025

    In this cross-sectional study, disparities in PPD were likely to reflect major inequality in access to health-enhancing technologies and living standards, as well as context-specific obstacles. Technological and medical advancements leading to universal health benefits need to be rapidly and fairly disseminated

  • Differential effect of China’s Zero Markup Drug Policy on provider-induced demand in secondary and tertiary hospitals

    Open AccessXiaoxi Zhang, Armand Zimmerman et al.ARTICLEFrontiers in Public Health2024

    Following the marketization of China’s health system in the 1980’s, the government allowed public hospitals to markup the price of certain medications by 15% to compensate for reduced revenue from government subsidies. This incentivized clinicians to induce patient demand for drugs which resulted in higher patient out-of-pocket payments, higher overall medical expenditure, and poor health outcomes. In 2009, China introduced the Zero Markup Drug P…

  • Cost-effectiveness analysis of proactive home visits compared with site-based community health worker care on antenatal care outcomes in Mali

    Open AccessOsondu Ogbuoji, Minahil Shahid et al.ARTICLEBMJ Global Health2024

    INTRODUCTION: Despite recommendations from the WHO, antenatal care (ANC) coverage remains low in many low-income and middle-income countries (LMICs). Community health workers (CHWs) can play an important role in expanding ANC coverage through pregnancy identification, provision of health education, screening for complications, delivery of therapeutic care and referral to higher levels of care. However, despite the success of CHW programmes in var…

  • Strengthening regulation for medical products in Tanzania

    Open AccessAdam M Fimbo, Hiiti B Sillo et al.ARTICLEPLOS Global Public Health2024

    Improving medicines regulation can lead to better population health, but how this process works in low- and middle-income countries remains underexplored. Tanzania’s pharmaceutical sector is often cited as a successful example of a well-functioning regulatory system in a developing country, attributed to the work of the Tanzania Food and Drugs Authority (TFDA), now the Tanzania Medicines and Medical Devices Authority (TMDA). This raises the quest…

  • Modeling the global impact of reducing out-of-pocket costs for children’s surgical care

    Open AccessEmily R Smith, Pamela Espinoza et al.ARTICLEPLOS Global Public Health2024

    Over 1.7 billion children lack access to surgical care, mostly in low- and middle-income countries (LMICs), with substantial risks of catastrophic health expenditures (CHE) and impoverishment. Increasing interest in reducing out-of-pocket (OOP) expenditures as a tool to reduce the rate of poverty is growing. However, the impact of reducing OOP expenditures on CHE remains poorly understood. The purpose of this study was to estimate the global impa…

  • A cost-effectiveness analysis of a South African pregnancy support grant

    Open AccessAisha Moolla, Winfrida Mdewa et al.ARTICLEPLOS Global Public Health2024

    Poverty among expectant mothers often results in sub-optimal maternal nutrition and inadequate antenatal care, with negative consequences on child health outcomes. South Africa has a child support grant that is available from birth to those in need. This study aims to determine whether a pregnancy support grant, administered through the extension of the child support grant, would be cost-effective compared to the existing child support grant alon…

  • Are households with under-five children in Nigeria socioeconomically disadvantaged

    Open AccessAshwini Sunil Deshpande, Osondu Ogbuoji et al.ARTICLEPLOS Global Public Health2024

    Although the sociodemographic and economic contributors to under-five mortality are well established, very little research has been done to assess the levels of disadvantage under-five children in Nigeria face along these dimensions. Nigeria has the second-highest under-five mortality rate (U5MR) in the world (111 deaths per 1000 live births) and contributed to the highest number of annual under-five deaths globally in 2020 (844,321 deaths). The …

  • Health reform in Nigeria

    Open AccessKevin Croke, Osondu OgbuojiARTICLEHealth Policy and Planning2024

    Over the past decade, Nigeria has seen major attempts to strengthen primary health care, through the Saving One Million Lives (SOML) initiative, and to move towards universal health care, through the National Health Act. Both initiatives were successfully adopted, but faced political and institutional challenges in implementation and sustainability. We analyse these programmes from a political economy perspective, examining barriers to and facili…

  • United Kingdom aid cuts

    Open AccessKaci Kennedy Mcdade, Wenhui Mao et al.ARTICLEFrontiers in Public Health2023

    Background: The United Kingdom (UK) used to be the second largest bilateral provider of official development assistance (ODA) for health. However, in 2021 the UK government cut its annual aid budget by 30%. We aim to understand how these cuts might affect financing for health systems in UK aid recipient countries. Methods: We conducted a retrospective analysis of domestic and external funding for 134 countries that received UK aid for the 2019-20…

  • Investing in a global pooled-funding mechanism for late-stage clinical trials of poverty-related and neglected diseases

    Open AccessArmand Zimmerman, Mohamed Mustafa Diab et al.ARTICLEBMJ Global Health2023

    INTRODUCTION: Poverty-related and neglected diseases (PRNDs) cause over three million deaths annually. Despite this burden, there is a large gap between actual funding for PRND research and development (R&D) and the funding needed to launch PRND products from the R&D pipeline. This study provides an economic evaluation of a theoretical global pooled-funding mechanism to finance late-stage clinical trials of PRND products. METHODS: We modelled thr…

  • Strategic donor behaviour and country vulnerability in health aid transitions

    Open AccessWenhui Mao, Kaci Kennedy Mcdade et al.ARTICLEBMJ Global Health2023

    BACKGROUND: When countries reach the middle-income threshold, many multilateral donors, including Gavi, the Vaccine Alliance (Gavi), begin to withdraw their official development assistance (ODA), known as graduation. We hypothesised that bilateral donors might follow Gavi's lead, except in countries where they have strategic interests. We aim to understand how bilateral donors behave after a recipient country graduates from Gavi support and how b…

METHODS: We conducted a benef…

  • Coverage of social assistance in Ethiopia during the Covid-19 pandemic

    Open AccessAshwini Sunil Deshpande, Addis Kassahun Mulat et al.ARTICLEBMJ Global Health2022

    OBJECTIVE: In a pandemic, government assistance is essential to support the most vulnerable households as they face health and economic challenges. However, government assistance is effective only when it reaches vulnerable households in time. In this paper, we estimated the timeliness of government assistance for the most vulnerable households (ie, the poor households) in Ethiopia during its COVID-19 response of 2020. In particular, we conducted…

  • Perspectives of frontline health workers on transition from development assistance for health in Ghana

    Open AccessSandra Appiah-Kubi, Wenhui Mao et al.ARTICLEPLOS Global Public Health2022

    Many Low-income countries depend on development assistance for health (DAH) to finance the health sector. The transition of these countries to middle-income status has led to reduction in effective aid from development partners while these countries are expected to graduate from global funding agencies such as Gavi the vaccine alliance, with implications for service delivery. The aim of this study was to explore the perspectives of frontline heal…

  • The impacts of donor transitions on health systems in middle-income countries

    Open AccessHanna E Huffstetler, Shashika Bandara et al.ARTICLEHealth Policy and Planning2022

    As countries graduate from low-income to middle-income status, many face losses in development assistance for health and must ‘transition’ to greater domestic funding of their health response. If improperly managed, donor transitions in middle-income countries (MICs) could present significant challenges to global health progress. No prior knowledge synthesis has comprehensively surveyed how donor transitions can affect health systems in MICs. We …

  • Transitioning from donor aid for health

    Open AccessWenhui Mao, Kaci Kennedy Mcdade et al.ARTICLEBMJ Global Health2021

    BACKGROUND: Ghana's shift from low-income to middle-income status will make it ineligible to receive concessional aid in the future. While transition may be a reflection of positive changes in a country, such as economic development or health progress, a loss of support from donor agencies could have negative impacts on health system performance and population health. We aimed to identify key challenges and opportunities that Ghana will face in d…
