Chatbots and COVID-19: Taking Stock of the Lessons Learned.

While digital innovation in health was already rapidly evolving, the COVID-19 pandemic has accelerated the generation of digital technology tools, such as chatbots, to help increase access to crucial health information and services to those who were cut off or had limited contact with health services. This theme issue titled "Chatbots and COVID-19" presents articles from researchers and practitioners across the globe, describing the development, implementation, and evaluation of chatbots designed to address a wide range of health concerns and services. In this editorial, we present some of the key challenges and lessons learned arising from the content of this theme issue. Most notably, we note that a stronger evidence base is needed to ensure that chatbots and other digital tools are developed to best serve the needs of population health.

Enabling cross-country learning and exchange to support universal health coverage implementation.

As countries transition from external assistance while pursuing ambitious plans to achieve universal health coverage (UHC), there is increasing need to facilitate knowledge sharing and learning among them. Country-led and country-owned knowledge management is foundational to sustainable, more equitable external assistance for health and is a useful complement to more conventional capacity-building modalities provided under external assistance. In the context of external assistance, few initiatives use country-to-country sharing of practitioner experiences, and link learning to receiving guidance on how to adapt, apply and sustain policy changes. Dominant knowledge exchange processes are didactic, implicitly assuming static technical needs, and that practitioners in low- and middle-income countries require problem-specific, time-bound solutions. In reality, the technical challenges of achieving UHC and the group of policymakers involved continuously evolve. This paper aims to explore factors which are supportive of experience-based knowledge exchange between practitioners from diverse settings, drawing from the experience of the Joint Learning Network (JLN) for UHC-a global network of practitioners and policymakers sharing experiences about common challenges to develop and implement knowledge products supporting reforms for UHC-as an illustration of a peer-to-peer learning approach. This paper considers: (1) an analysis of JLN monitoring and evaluation data between 2020 and 2023 and (2) a qualitative inquiry to explore policymakers' engagement with the JLN using semi-structured interviews (n = 14) with stakeholders from 10 countries. The JLN's experience provides insights to factors that contribute to successful peer-to-peer learning approaches. JLN relies on engaging a network of practitioners with diverse experiences who organically identify and pursue a common learning agenda. Meaningful peer-to-peer learning requires dynamic, structured interactions, and alignment with windows of opportunity for implementation that enable rapid response to emerging and timely issues. Peer-to-peer learning can facilitate in-country knowledge sharing, learning and catalyse action at the institutional and health system levels.

Framing health taxes: learning from low- and middle-income countries.

Health taxes are effective policy instruments to save lives, raise government revenues and improve equity. Health taxes, however, directly conflict with commercial actors' interests. Both pro-tax health advocates and anti-tax industry representatives seek to frame health tax policy. Yet, little is known about which frames resonate in which settings and how framing can most effectively advance or limit policies. To fill this gap, we conducted qualitative research in 2022, including focus group discussions, in-depth interviews, document reviews and media analysis on the political economy of health taxes across eight low-income and middle-income countries. Studies captured multiple actors constructing context-specific frames, often tied to broader economic, health and administrative considerations. Findings suggest that no single frame dominates; in fact, a plurality of different frames exist and shape discourse and policymaking. There was no clear trade-off between health and economic framing of health tax policy proposals, nor a straightforward way to handle concerns around earmarking. Understanding how to best position health taxes can empower health policymakers with more persuasive framings for health taxes and can support them to develop broader coalitions to advance health taxes. These insights can improve efforts to advance health taxes by better appreciating political economy factors and constraining corporate power, ultimately leading to improved population-level health.

Framing health taxes: a scoping review.

Health taxes are increasingly positioned as effective policy instruments for curbing non-communicable disease, improving health and raising government revenues. Their allure has caused many health advocates to look beyond tobacco and alcohol to other harmful products such as sugar-sweetened beverages (SSBs), salty foods, fatty foods and fossil fuels. These efforts, however, directly conflict with commercial actors' interests. Both pro-tax health advocates and anti-tax industry representatives seek to frame health tax policy in favourable ways. Yet, little is known about which types of frames resonate in which settings, or how they deploy morals and values in their attempts to persuade. To fill this gap, we conducted a scoping review on framing health taxes using six databases in 2022. A total of 40 peer-reviewed empirical research articles, from 2006 to 2022, were identified from 20 different countries. Most research was conducted in high-income countries, published in the last 4 years and increasingly focused on excise taxes for SSBs. Studies captured multiple actors constructing context-specific frames, often tied to broader economic, health and administrative considerations. Actors also engaged in a range of political activities in addition to framing. We found some evidence that anti-tax framing strategies potentially incorporated a broader array of morals and social values. More in-country comparative research, particularly from low/middle-income countries, is needed to understand the politics of framing health taxes. We argue that these insights can improve efforts to advance health taxes by constraining corporate power, improving population level health and promoting greater social harmony.

Embedding rapid reviews in health policy and systems decision-making: Impacts and lessons learned from four low- and middle-income countries.

BACKGROUND: Demand for rapid evidence-based syntheses to inform health policy and systems decision-making has increased worldwide, including in low- and middle-income countries (LMICs). To promote use of rapid syntheses in LMICs, the WHO's Alliance for Health Policy and Systems Research (AHPSR) created the Embedding Rapid Reviews in Health Systems Decision-Making (ERA) Initiative. Following a call for proposals, four LMICs were selected (Georgia, India, Malaysia and Zimbabwe) and supported for 1 year to embed rapid response platforms within a public institution with a health policy or systems decision-making mandate. METHODS: While the selected platforms had experience in health policy and systems research and evidence syntheses, platforms were less confident conducting rapid evidence syntheses. A technical assistance centre (TAC) was created from the outset to develop and lead a capacity-strengthening program for rapid syntheses, tailored to the platforms based on their original proposals and needs as assessed in a baseline questionnaire. The program included training in rapid synthesis methods, as well as generating synthesis demand, engaging knowledge users and ensuring knowledge uptake. Modalities included live training webinars, in-country workshops and support through phone, email and an online platform. LMICs provided regular updates on policy-makers' requests and the rapid products provided, as well as barriers, facilitators and impacts. Post-initiative, platforms were surveyed. RESULTS: Platforms provided rapid syntheses across a range of AHPSR themes, and successfully engaged national- and state-level policy-makers. Examples of substantial policy impact were observed, including for COVID-19. Although the post-initiative survey response rate was low, three quarters of those responding felt confident in their ability to conduct a rapid evidence synthesis. Lessons learned coalesced around three themes - the importance of context-specific expertise in conducting reviews, facilitating cross-platform learning, and planning for platform sustainability. CONCLUSIONS: The ERA initiative successfully established rapid response platforms in four LMICs. The short timeframe limited the number of rapid products produced, but there were examples of substantial impact and growing demand. We emphasize that LMICs can and should be involved not only in identifying and articulating needs but as co-designers in their own capacity-strengthening programs. More time is required to assess whether these platforms will be sustained for the long-term.

An exploration of stakeholder views and perceptions on taxing tobacco, alcohol and sugar-sweetened beverages in Ghana.

BACKGROUND: Non-communicable diseases (NCDs) account for nearly 43% of Ghana's all-cause mortality. Unhealthy commodities (such as alcohol, sugar and tobacco) are an important factor in the growing NCD burden in the region of sub-Saharan Africa (SSA). Despite health taxes on tobacco, alcohol and sugar-sweetened beverages (SSBs) gaining renewed attention, adoption and implementation in SSA remain limited. This study aims to unpack the contextual politics and to examine current perceptions of opportunities and barriers for health taxes in Ghana. METHODS: Semistructured qualitative interviews (n=19) conducted with purposively sampled stakeholders representing four sectors: government, civil society, media and international organisations, and two group interviews with nine industry stakeholders, informed by a review of relevant literature and policy/advocacy documents. RESULTS: Stakeholders had a general belief that such taxes are primarily useful for revenue generation (for health spending) rather than for reducing consumption and improving health. There do appear to be opportunities for health taxes with stakeholders broadly supportive of taxing SSBs. This support could be strengthened via 'health' framing of any new tax proposals, the generation of Ghana-specific evidence about the potential impacts of such taxes and greater public awareness. Industry actors and some government representatives opposed health taxes, citing concerns about the potential to increase illicit trade and economic harm. Some stakeholders also believed that links between politicians and affected industries represent an important barrier. CONCLUSION: These findings identify opportunities to introduce health taxes but also underline the potential resistance from affected industry stakeholders. Nevertheless, a strategic approach that focuses on achieving policy coherence (between central government, health and economic ministries), combined with efforts to strengthen stakeholder and public support, may weaken the lobbying position of industry. Such efforts could be supported by research to help demonstrate the value of different designs of health taxes for achieving Ghana's health goals and to better understand industry-political links.

Characteristics of successful government-led interventions to support healthier populations: a starting portfolio of positive outlier examples.

Despite progress on the Millennium and Sustainable Development Goals, significant public health challenges remain to address communicable and non-communicable diseases and health inequities. The Healthier Societies for Healthy Populations initiative convened by WHO's Alliance for Health Policy and Systems Research; the Government of Sweden; and the Wellcome Trust aims to address these complex challenges. One starting point is to build understanding of the characteristics of successful government-led interventions to support healthier populations. To this end, this project explored five purposefully sampled, successful public health initiatives: front-of-package warnings on food labels containing high sugar, sodium or saturated fat (Chile); healthy food initiatives (trans fats, calorie labelling, cap on beverage size; New York); the alcohol sales and transport ban during COVID-19 (South Africa); the Vision Zero road safety initiative (Sweden) and establishment of the Thai Health Promotion Foundation. For each initiative a qualitative, semistructured one-on-one interview with a key leader was conducted, supplemented by a rapid literature scan with input from an information specialist. Thematic analysis of the five interviews and 169 relevant studies across the five examples identified facilitators of success including political leadership, public education, multifaceted approaches, stable funding and planning for opposition. Barriers included industry opposition, the complex nature of public health challenges and poor interagency and multisector co-ordination. Further examples building on this global portfolio will deepen understanding of success factors or failures over time in this critical area.

Commercial determinants of health: future directions.

This paper is about the future role of the commercial sector in global health and health equity. The discussion is not about the overthrow of capitalism nor a full-throated embrace of corporate partnerships. No single solution can eradicate the harms from the commercial determinants of health-the business models, practices, and products of market actors that damage health equity and human and planetary health and wellbeing. But evidence shows that progressive economic models, international frameworks, government regulation, compliance mechanisms for commercial entities, regenerative business types and models that incorporate health, social, and environmental goals, and strategic civil society mobilisation together offer possibilities of systemic, transformative change, reduce those harms arising from commercial forces, and foster human and planetary wellbeing. In our view, the most basic public health question is not whether the world has the resources or will to take such actions, but whether humanity can survive if society fails to make this effort.

Defining and conceptualising the commercial determinants of health.

Although commercial entities can contribute positively to health and society there is growing evidence that the products and practices of some commercial actors-notably the largest transnational corporations-are responsible for escalating rates of avoidable ill health, planetary damage, and social and health inequity; these problems are increasingly referred to as the commercial determinants of health. The climate emergency, the non-communicable disease epidemic, and that just four industry sectors (ie, tobacco, ultra-processed food, fossil fuel, and alcohol) already account for at least a third of global deaths illustrate the scale and huge economic cost of the problem. This paper, the first in a Series on the commercial determinants of health, explains how the shift towards market fundamentalism and increasingly powerful transnational corporations has created a pathological system in which commercial actors are increasingly enabled to cause harm and externalise the costs of doing so. Consequently, as harms to human and planetary health increase, commercial sector wealth and power increase, whereas the countervailing forces having to meet these costs (notably individuals, governments, and civil society organisations) become correspondingly impoverished and disempowered or captured by commercial interests. This power imbalance leads to policy inertia; although many policy solutions are available, they are not being implemented. Health harms are escalating, leaving health-care systems increasingly unable to cope. Governments can and must act to improve, rather than continue to threaten, the wellbeing of future generations, development, and economic growth.

How states engage in and exercise power in global health: Indonesian and Japanese engagement in the conceptualization of Sustainable Development Goal 3.

While long overlooked, power is central to understand how actors engage in global health policymaking. We reviewed how the Japanese and Indonesian governments exerted power and engaged in global health diplomacy during negotiations to conceptualize the post-2015 Sustainable Development Goal for health (SDG3). We conducted deliberative policy analysis including semi-structured, in-depth, interviews with more than 71 policymakers, which we analyzed adapting Barnett and Duvall's power framework. We find that both Japan and Indonesia exerted non-material power (institutional, productive and structural power) to advance largely domestic political interests. Japan's government mainly exerted institutional power, leveraging relationships within the World Bank and the World Health Organization, whereas Indonesia's government focused on structural power, with its president serving as co-chair of the UN Secretary-General's High-Level Post-2015 Panel. Our analysis suggests that the ways in which states engage in global health diplomacy is shaped by the relationship between different intra-state institutions, particularly the Ministry of Foreign Affairs and the Ministry of Health, and is further determined by broader foreign policy and diplomatic priorities. We find that the decline of states' influence is over-stated: states continue to exercise significant power in global health diplomacy, pursuing domestic political imperatives and strategies to improve population health. As states expand their global health engagement, researchers should seek to better understand how states participate in an increasingly crowded and contested global health field.

What Are Healthy Societies? A Thematic Analysis of Relevant Conceptual Frameworks.

BACKGROUND: While support for the idea of fostering healthy societies is longstanding, there is a gap in the literature on what they are, how to beget them, and how experience might inform future efforts. This paper explores developments since Alma Ata (1978) to understand how a range of related concepts and fields inform approaches to healthy societies and to develop a model to help conceptualize future research and policy initiatives. METHODS: Drawing on 68 purposively selected documents, including political declarations, commission and agency reports, peer-reviewed papers and guidance notes, we undertook qualitative thematic analysis. Three independent researchers compiled and categorised themes describing the domains of a potential healthy societies approach. RESULTS: The literature provides numerous frameworks. Some of these frameworks promote alternative endpoints to development, eschewing short-term economic growth in favour of health, equity, well-being and sustainability. They also identify values, such as gender equality, collaboration, human rights and empowerment that provide the pathways to, or underpin, such endpoints. We categorize the literature into four "components": people; places; products; and planet. People refers to social positions, interactions and networks creating well-being. Places are physical environments-built and natural-and the interests and policies shaping them. Products are commodities and commercial practices impacting population health. Planet places human health in the context of the 'Anthropocene.' These components interact in complex ways across global, regional, country and community levels as outlined in our heuristic. CONCLUSION: The literature offers little critical reflection on why greater progress has not been made, or on the need to organise and resist the prevailing systems which perpetuate ill-health.

How to Build Healthy Societies: A Thematic Analysis of Relevant Conceptual Frameworks.

BACKGROUND: As the Sustainable Development Goals deadline of 2030 draws near, greater attention is being given to health beyond the health sector, in other words, to the creation of healthy societies. However, action and reform in this area has not kept pace, in part due to a focus on narrower interventions and the lack of upstream action on health inequity. With an aim to guide action and political engagement for reform, we conducted a thematic analysis of concepts seeking to arrive at healthy societies. METHODS: This paper drew on a qualitative thematic analysis of a purposive sample of 68 documents including political declarations, reports, peer reviewed literature and guidance published since 1974. Three independent reviewers extracted data to identify, discuss and critique public policy levers and 'enablers' of healthy societies, the "how." RESULTS: The first lever concerned regulatory and fiscal measures. The second was intersectoral action. The final lever a shift in the global consensus around what signifies societal transformation and outcomes. The three enablers covered political leadership and accountability, popular mobilization and the generation and use of knowledge. CONCLUSION: Documents focused largely on technical rather than political solutions. Even as the importance of political leadership was recognized, analysis of power was limited. Rights-based approaches were generally neglected as was assessing what worked or did not work to pull the levers or invest in the enablers. Frameworks typically failed to acknowledge or challenge prevailing ideologies, and did not seek to identify ways to hold or governments or corporations accountable for failures. Finally, ideas and approaches seem to recur again over the decades, without adding further nuance or analysis. This suggests a need for more upstream, critical and radical approaches to achieve healthy societies.

Describing and mapping scientific articles on alcohol globally for the period 2010-2021: a bibliometric analysis.

OBJECTIVES: To describe and map scientific literature related to alcohol consumption, its determinants, governance, harm and control policies by publication output, author affiliations, funding, countries of study and research themes. DESIGN: Bibliometric analysis using performance analysis and science mapping techniques. DATA SOURCES: Scientific articles. ELIGIBILITY CRITERIA: Indexed scientific articles published between 1 January 2010 and 31 December 2021 with an English abstract focused on alcohol consumption, its determinants, harms, governance and control policies. DATA EXTRACTION AND SYNTHESIS: Searches were run in Web of Science and PubMed. Performance metrics were analysed using descriptive statistics. Keywords were used for science mapping in a deductive approach to cluster articles by five main research themes. The 'policy response' theme was further analysed by six subthemes. RESULTS: 4553 articles were included in the analysis. Three out of four articles (3479/4553, 76.4%) were authored solely by authors affiliated with HIC institutions. One in five articles (906/4553, 19.9%) had at least one author affiliated to an institution from an upper-middle-income, middle-income or low-income country context. Governments, followed by research institutions, were the predominant funding source. Half (53.1%) studied a single country and, of these, 77.0% were high-income countries (HICs). Australia, USA and UK were the most studied countries, together accounting for 44.9% (975/2172) of country-specific articles. Thematically, 'consumption' was most studied, and 'alcohol determinants', least. 'Policy response' articles were predominately conducted in HIC contexts. CONCLUSIONS: Although the attributable harm of alcohol is known to affect more significantly lower-income and middle-income countries, scientific publications primarily report on HIC contexts by authors from HICs. Research themes reflect known cost-effective policy actions, though skewed towards HICs and a focus on consumption. The implementation of context-specific alcohol control policies requires addressing the determinants of the uneven geographical and thematic distribution of research.
