Despite some progress, universal access to safe water, sanitation and hygiene (WASH) by 2030-a remit of Sustainable Development Goal 6-remains a distant prospect in many countries. Policy-makers and implementers of the WASH sector are challenged to track a new path. This research aimed to identify core orienting themes of the sector, as legacies of past processes, which can provide insights for its future. We reviewed global policy, science and programmatic documents and carried out 19 expert interviews to track the evolution of the global WASH sector over seven decades. We situated this evolution in relation to wider trends in global health and development over the same time period.With transnational flows of concern, expertise and resources from high-income to lower-income countries, the WASH sector evolved over decades of international institutionalisation of health and development with (1) a focus on technologies (technicalisation), (2) a search for generalised solutions (universalisation), (3) attempts to make recipients responsible for environmental health (responsibilisation) and (4) the shaping of programmes around quantifiable outcomes (metricisation). The emergent commitment of the WASH sector to these core themes reflects a pragmatic response in health and development to depoliticise poverty and social inequalities in order to enable action. This leads to questions about what potential solutions have been obscured, a recognition which might be understood as 'uncomfortable knowledge'-the knowns that have had to be unknown, which resonate with concerns about deep inequalities, shrinking budgets and the gap between what could and has been achieved.

Introduction: Non-prescription antibiotic dispensing is prevalent among community pharmacies in several low- and middle-income countries. We evaluated the impact of a multi-faceted intervention to address this challenge in urban community pharmacies in Indonesia.

Methods: A pre-post quasi-experimental study was carried out in Semarang city from January to August 2022 to evaluate a 7-month long intervention comprising: (1) online educational sessions for pharmacists; (2) awareness campaign targeting customers; (3) peer visits; and (4) pharmacy branding and pharmacist certification. All community pharmacies were invited to take part with consenting pharmacies assigned to the participating group and all remaining pharmacies to the non-participating group. The primary outcome (rate of non-prescription antibiotic dispensing) was measured by standardised patients displaying symptoms of upper respiratory tract infection, urinary tract infection (UTI) and seeking care for diarrhoea in a child. χ² tests and multivariate random-effects logistic regression models were conducted. Thirty in-depth interviews were conducted with pharmacists, staff and owners as well as other relevant stakeholders to understand any persistent barriers to prescription-based dispensing of antibiotics.

Findings: Eighty pharmacies participated in the study. Postintervention, non-prescription antibiotics were dispensed in 133/240 (55.4%) consultations in the participating group compared with 469/570 (82.3%) in the non-participating group (p value <0.001). The pre-post difference in the non-prescription antibiotic dispensing rate in the participating group was 20.9% (76.3%-55.4%) compared with 2.3% (84.6%-82.3%) in the non-participating group (p value <0.001).Non-prescription antibiotics were less likely to be dispensed in the participating group (OR=0.19 (95% CI 0.09 to 0.43)) and more likely to be dispensed for the UTI scenario (OR=3.29 (95% CI 1.56 to 6.94)). Barriers to prescription-based antibiotic dispensing included fear of losing customers, customer demand, and no supervising pharmacist present.

Interpretation: Multifaceted interventions targeting community pharmacies can substantially reduce non-prescription antibiotic dispensing. Future studies to evaluate the implementation and sustainability of this intervention on a larger scale are needed.

Background: Cost-effectiveness evidence is a critical tool to support resource allocation decisions. There is growing recognition that the development of benefit packages for surgical care should be guided by such evidence, particularly in resource-constraint settings.

Methods: We conducted a systematic review of evidence (Medline, Embase, Global Health, EconLit and grey literature) on the cost-effectiveness of surgery across low-income and middle-income countries published between January 2013 and January 2023. We included studies with minor and major therapeutic surgeries and minimally invasive intraluminal and endovascular interventions. We computed and compared the average cost-effectiveness ratios (ACERs) for different surgical interventions to the respective national gross domestic product per capita to determine cost-effectiveness and to common traditional public health interventions.

Results: We identified 87 unique studies out of 20 070 articles screened. Studies spanned 23 countries, with China (n=20), Thailand (n=12), Brazil (n=8) and Iran (n=8) accounting for about 55% of the evidence. Overall, the median ACERs across procedure groups ranged from I$17/disability-adjusted life year (DALY) for laparotomies to I$170 186/DALY for bariatric surgeries. Most of the ACER estimates were classified as cost-effective (89%) or very cost-effective (76%). Low-complexity surgical interventions compared favourably to common public health interventions.

Conclusion: These findings reinforce the growing body of evidence that investments in surgery are economically smart. There remains however paucity of high-quality evidence that would allow decision-makers to assess the comparative cost-effectiveness of surgery and to determine best buys across a wide range of specialties and interventions. A concerted effort is needed to advance the generation and utilisation of economic evidence in the drive towards scale-up of surgical care across low-income and middle-income countries.

The Montreal Protocol has played a critical role in promoting global collective action to phase out the use of ozone-depleting substances, ultimately preventing millions of cases of skin cancer, cataracts and other health issues related to ultraviolet radiation exposure. This success entails transferable lessons for coordinated action required to improve the global governance of other challenges. Like ozone depletion, antimicrobial resistance (AMR) is a challenge of the global commons, requiring coordinated actions across human, animal and environmental sectors. We identify equity, flexibility and accountability as three core governance principles that underlie the success of the protocol and employ the 3-i framework to understand how interests, ideas and institutions contributed to the protocol's success. Equity-promoting strategies consisted of an inclusive negotiation process, supporting developing countries with multilateral funding and a progressive compliance model. Flexibility was built into the protocol through the development of country-specific strategies, reorienting incentive structures for industry and facilitating regular amendments in response to emerging scientific evidence. Accountability was promoted by mobilising public advocacy, establishing targets and enforcement mechanisms and conducting independent scientific and technical assessments. Applying our proposed principles presents an opportunity to improve the global governance of AMR. Finally, we acknowledge limitations to our analysis, including our focus on a single environmental treaty, significantly greater funding requirements and multifacetted stakeholder involvement in the case of AMR, differing market and incentives structures in antibiotic development and distribution, and ethical concerns with using trade restrictions as a policy tool.

Background: The WHO declared the novel COVID-19 outbreak a pandemic in March 2020. While the COVID-19 pandemic was unprecedented, prior experiences with diseases such as Middle East respiratory syndrome, severe acute respiratory syndrome and Ebola shaped many countries' preparedness and response strategies. Although lessons learnt from outbreak responses have been documented from a variety of sources, news media play a special role through their dissemination of news to the general public. This study investigated news media to explore how lessons learnt from the West African Ebola outbreak in 2014-2016 informed the COVID-19 responses in several African countries.

Methods: We conducted qualitative analysis on a dataset of previously compiled COVID-19-related news articles published from 1 March 2020 to 31 August 2020. This dataset included 34,225 articles from 6 countries. We filtered the dataset to only include articles with the keyword 'Ebola'. We used a machine-learning text classification model to identify relevant articles with clear and specific lessons learnt. We conducted inductive and deductive coding to categorise lessons learnt and identify emergent themes.

Results: Of the 861 articles containing the word 'Ebola', 18.4% (N=158) with lessons learnt from Ebola were included across five of the countries: Ethiopia, Ghana, Kenya, Liberia and Sierra Leone. News articles highlighted three emergent themes: the importance of leveraging existing resources and past response system investments, promoting transparency in public health messaging and engaging community leaders in all phases of the response.

Conclusions: Findings suggest fostering trust prior to and throughout an outbreak facilitates timely implementation and compliance of mitigation strategies. Trust can be built by leveraging existing resources, being communicative and transparent about their funding allocation and decision-making and engaging communities.

Low- and middle-income countries (LMICs) contribute relatively little to global carbon emissions but are recognised to be among the most vulnerable parts of the world to health-related consequences of climate change. To help inform resilient health systems and health policy strategies, we sought to systematically analyse published projections of the impact of rising global temperatures and other weather-related events on human health in LMICs. A systematic search involving multiple databases was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify studies with modelled projections of the future impact of climate change on human health. Qualitative studies, reviews and meta-analyses were excluded. The search yielded more than 2500 articles, of which 70 studies involving 37 countries met criteria for inclusion. China, Brazil and India were the most studied countries while the sub-Saharan African region was represented in only 9% of studies. Forty specific health outcomes were grouped into eight categories. Non-disease-specific temperature-related mortality was the most studied health outcome, followed by neglected tropical infections (predominantly dengue), malaria and cardiovascular diseases. Nearly all health outcomes studied were projected to increase in burden and/or experience a geographic shift in prevalence over the next century due to climate change. Progressively severe climate change scenarios were associated with worse health outcomes. Knowledge gaps identified in this analysis included insufficient studies of various high burden diseases, asymmetric distribution of studies across LMICs and limited use of some climate parameters as independent variables. Findings from this review could be the basis for future research to help inform climate mitigation and adaptation programmes aimed at safeguarding population health in LMICs.

Enhancing digital health governance is critical to healthcare systems in low-income and middle-income countries. However, implementing governance-enhancing reforms in these countries is often challenging due to the multiplicity of external players and insufficient operational guidance that is accessible. Using data from desktop research, in-depth interviews, focus group discussions and three stakeholder workshops, this paper aims to provide insights into Georgia's experience in advancing digital health governance reforms. It reveals how Georgia has progressed on this path by unpacking the general term 'governance' into operational domains, where stakeholders and involved institutions could easily relate their institutional and personal roles and responsibilities with the specific function needed for digital health. Based on this work, the country delineated institutional responsibilities and passed the necessary regulations to establish better governance arrangements for digital health. The Georgia experience provides practical insights into the challenges faced and solutions found for advancing digital health governance in a middle-income country setting. The paper highlights the usefulness of operational definitions for the digital health governance domains that helped (a) increase awareness among stakeholders about the identified domains and their meaning, (b) discuss possible governance and institutional arrangements relevant to a country context, and (c) design the digital health governance architecture that the government decreed. Finally, the paper offers a broad description of domains in which the governance arrangements could be considered and used for other settings where relevant. The paper points to the need for a comprehensive taxonomy for governance domains to better guide digital health governance enhancements in low-middle-income country settings.

Background: Throughout the Syrian conflict, the Syrian government has intentionally attacked health facilities, violating International Humanitarian Law. Previous studies have qualitatively described health system disruptions following attacks on healthcare or established associations between armed conflict and health service utilisation, but there are no quantitative studies exploring the effects of health facility attacks. Our unprecedented study addresses this gap by quantifying the effects of health facility attacks on health service use during the Syrian conflict.

Methods: This retrospective observational study uses 18 537 reports capturing 2 826 627 consultations from 18 health facilities in northwest Syria and 69 attacks on these facilities. The novel study applies case time series design with a generalised non-linear model and stratification by facility type, attack mechanism and corroboration status.

Results: The study found significant, negative associations between health facility attacks and outpatient, trauma and facility births. On average, a health facility attack was associated with 51% and 38% reductions in outpatient, RR 0.49 (95% CI 0.43 to 0.57) and trauma consultations, RR 0.62 (95% CI 0.53 to 0.72), the day after an attack, with significant reductions continuing for 37 and 20 days, respectively. Health facility attacks were associated with an average 23% reduction in facility births, the second day after an attack, RR 0.77 (95% CI 0.66 to 0.89), with significant reductions continuing for 42 days.

Conclusions: Attacks on health facilities in northwest Syria are strongly associated with significant reductions in outpatient, trauma and facility births. These attacks exacerbate the adverse effects of armed conflict and impede the fundamental right to health. The findings provide evidence that attacks on health facilities, violations of international humanitarian law by themselves, also negatively affect human rights by limiting access to health services, underscoring the need to strengthen health system resilience in conflict settings, expand systematic reporting of attacks on healthcare and hold perpetrators accountable.
