Tensions and opportunities in the roles of senior public health officials in Canada: A qualitative study.

Although public health emergencies like the COVID-19 pandemic thrust senior public health officials into the spotlight, their day-to-day roles remain misunderstood and under-examined. In jurisdictions that follow the Westminster system of government such as Canada, the United Kingdom, and Australia, Chief Medical Officers of Health (CMOHs) are typically senior public servants who are simultaneously positioned as public health professionals with independent expertise, senior advisors to an elected government, and designated protectors of the public health interest. Using Canada's federal and provincial CMOHs as case studies of this role in Westminster governments, we analyzed in-depth key informant interview data to examine how CMOHs navigate the tensions among their duties to the government, profession, and public in order to maximize their public health impact. We demonstrate that CMOHs are variously called upon to be government advisors, public health managers, and public communicators, and that the different emphasis that jurisdictions place on these roles shapes the tools and pathways through which CMOHs can influence government action and public health. We also elucidate the tensions associated with having CMOHs positioned within the senior levels of the public service and the strategies these officials use to balance their internal- and external-facing roles. Finally, we highlight the trade-offs among different institutional design options to inform decisions about the structure of the CMOH position in different contexts.

Under the spotlight: understanding the role of the Chief Medical Officer in a pandemic.

As the COVID-19 pandemic took hold in 2020, Chief Medical Officers (CMOs) entered the public spotlight like never before. Amidst this increased visibility, the role is deeply contested. Much of the disagreement concerns whether CMOs should act independently of the government: while some argue CMOs should act as independent voices who work to shape government policy to protect public health, others stress that CMOs are civil servants whose job is to support the government. The scope and diversity of debates about the CMO role can be explained by its inherently contradictory nature, which requires incumbents to balance their commitments as physicians with their mandates as civil servants who advise and speak on the government's behalf. The long-haul COVID-19 pandemic has further tested the CMO role and has shone light on its varying remits and expectations across different jurisdictions, institutions and contexts. It is perhaps unsurprising, then, that calls to amend the CMO role have emerged in some jurisdictions during the pandemic. However, any discussions about changing the CMO role need a stronger understanding of how different institutional and individual approaches impact what incumbents feel able to do, say and achieve. Based on an ongoing comparative analysis of the position across five countries with Westminster-style political systems, we provide an overview of the CMO role, explain its prominence in a pandemic, examine some debates surrounding the role and discuss a few unanswered empirical questions before describing our ongoing study in greater detail.

Comparing the regulation and incentivization of e-cigarettes across 97 countries.

E-cigarette use continues to increase globally despite uncertainty regarding their long-term health impacts and around their effectiveness for tobacco smoking cessation. This uncertainty creates unique challenges for governments as they attempt to optimally regulate and positively or negatively incentivize these products in a way that maximizes the public's health. Current approaches to e-cigarette regulation and incentivization fall within a spectrum of options ranging from a singular focus on health protection, whereby policies intend to prevent the dangers of e-cigarettes, to a singular focus on using e-cigarettes for harm reduction, whereby policies intend to reduce the more harmful effects of smoking tobacco. Regulation options include prohibition, component ban, and regulation as medicinal products, poisons, tobacco products, consumer products, and/or unique products. Incentivization options include taxation, subsidization, and providing a financial reward. Through comparative public policy analysis, this study describes, compares and assesses the variety of approaches that 97 countries have taken to regulate and incentivize e-cigarettes. The goal is to inform future decisions by governments on how they approach the public health challenge posed by e-cigarettes, building on a nuanced understanding of the complexities of this challenge and what other jurisdictions have already implemented and learned.

The case for developing a cohesive systems approach to research across unhealthy commodity industries.

OBJECTIVES: Most non-communicable diseases are preventable and largely driven by the consumption of harmful products, such as tobacco, alcohol, gambling and ultra-processed food and drink products, collectively termed unhealthy commodities. This paper explores the links between unhealthy commodity industries (UCIs), analyses the extent of alignment across their corporate political strategies, and proposes a cohesive systems approach to research across UCIs. METHODS: We held an expert consultation on analysing the involvement of UCIs in public health policy, conducted an analysis of business links across UCIs, and employed taxonomies of corporate political activity to collate, compare and illustrate strategies employed by the alcohol, ultra-processed food and drink products, tobacco and gambling industries. RESULTS: There are clear commonalities across UCIs' strategies in shaping evidence, employing narratives and framing techniques, constituency building and policy substitution. There is also consistent evidence of business links between UCIs, as well as complex relationships with government agencies, often allowing UCIs to engage in policy-making forums. This knowledge indicates that the role of all UCIs in public health policy would benefit from a common approach to analysis. This enables the development of a theoretical framework for understanding how UCIs influence the policy process. It highlights the need for a deeper and broader understanding of conflicts of interests and how to avoid them; and a broader conception of what constitutes strong evidence generated by a wider range of research types. CONCLUSION: UCIs employ shared strategies to shape public health policy, protecting business interests, and thereby contributing to the perpetuation of non-communicable diseases. A cohesive systems approach to research across UCIs is required to deepen shared understanding of this complex and interconnected area and also to inform a more effective and coherent response.

Lessons learned from COVID-19 for the post-antibiotic future.

INTRODUCTION: COVID-19 has rapidly and radically changed the face of human health and social interaction. As was the case with COVID-19, the world is similarly unprepared to respond to antimicrobial resistance (AMR) and the challenges it will produce. COVID-19 presents an opportunity to examine how the international community might better respond to the growing AMR threat. MAIN BODY: The impacts of COVID-19 have manifested in health system, economic, social, and global political implications. Increasing AMR will also present challenges in these domains. As seen with COVID-19, increasing healthcare usage and resource scarcity may lead to ethical dilemmas about prioritization of care; unemployment and economic downturn may disproportionately impact people in industries reliant on human interaction (especially women); and international cooperation may be compromised as nations strive to minimize outbreaks within their own borders. CONCLUSION: AMR represents a slow-moving disaster that offers a unique opportunity to proactively develop interventions to mitigate its impact. The world's attention is currently rightfully focused on responding to COVID-19, but there is a moral imperative to take stock of lessons learned and opportunities to prepare for the next global health emergency.

Governing antimicrobial resistance: a narrative review of global governance mechanisms.

Antimicrobial resistance (AMR), a central health challenge of the twenty first century, poses substantial population health risks, with deaths currently estimated to be around 700,000 per year globally. The international community has signaled its commitment to exploring and implementing effective policy responses to AMR, with a Global Action Plan on AMR approved by the World Health Assembly in 2015. Major governance challenges could thwart collective efforts to address AMR, along with limited knowledge about how to design effective global governance mechanisms. To identify common ground for more coordinated global actions we conducted a narrative review to map dominant ideas and academic debates about AMR governance. We found two categories of global governance mechanisms: binding and non-binding and discuss advantages and drawbacks of each. We suggest that a combination of non-binding and binding governance mechanisms supported by leading antimicrobial use countries and important AMR stakeholders, and informed by One Health principles, may be best suited to tackle AMR.

Communication about COVID-19 from Canadian provincial chief medical officers of health: a qualitative study.

BACKGROUND: During the coronavirus disease 2019 (COVID-19) crisis, Canada's provincial chief medical officers of health (CMOHs) have provided regular updates on the pandemic response. We sought to examine whether their messaging varied over time and whether it varied across jurisdictions. METHODS: We conducted a qualitative study of news releases from Canadian provincial government websites during the initial phases of the COVID-19 outbreak between Jan. 21 and Mar. 31, 2020. We performed content analysis using a predefined data extraction framework to derive themes. RESULTS: We identified 290 news releases. Four broad thematic categories emerged: describing the government's preparedness and capacity building, issuing recommendations and mandates, expressing reassurance and encouraging the public, and promoting public responsibility. Most of the news releases were prescriptive, conveying recommendations and mandates to slow transmission. Cross-jurisdictional variations in messaging reflected local realities, such as evidence of community transmission. Messaging also reflected changing information about the pandemic over time, shifting from a tone of reassurance early on, to a sudden emphasis on social distancing measures, to a concern with public responsibility to slow transmission. INTERPRETATION: Messaging across jurisdictions was generally consistent, and variations in the tone and timing of CMOH messaging aligned with different and changing realities across contexts. These findings indicate that when evaluating CMOHs' statements, it is critical to consider the context of the information they possess, the epidemiologic circumstances in their jurisdiction and the way the province has structured the CMOH role.

Building the political case for investing in public health and public health research.

Governments around the world vastly underinvest in public health, despite ever growing evidence demonstrating its economic and social benefits. Challenges in securing greater public health investment largely stem from the necessity for governments to demonstrate visible impacts within an election cycle, whereas public health initiatives operate over the long term and generally involve prevention, statistical lives and underlying conditions. It is time for the public health community to rethink its strategies and craft political wins by building a political case for investing in public health-which extends far beyond mere economic and social arguments. These strategies need to make public health visible, account for the complexities of policymaking networks and adapt knowledge translation efforts to the appropriate policy instrument.

Towards a Systematic Understanding of How to Institutionally Design Scientific Advisory Committees: A Conceptual Framework and Introduction to a Special Journal Issue.

Scientifically-derived insights are often held as requirements for defensible policy choices. Scientific advisory committees (SACs) figure prominently in this landscape, often with the promise of bringing scientific evidence to decision-makers. Yet, there is sparse and scattered knowledge about what institutional features influence the operations and effectiveness of SACs, how these design choices influence subsequent decision-making, and the lessons learned from their application. The consequences of these knowledge gaps are that SACs may not be functioning as effectively as possible. The articles in this special journal issue of Global Challenges bring together insights from experts across several disciplines, all of whom are committed to improving SACs' effectiveness worldwide. The aim of the special issue is to inform future SAC design in order to help maximize the application of high-quality scientific research for the decisions of policymakers, practitioners, and the public alike. In addition to providing an overview of the special issue and a summary of each article within it, this introductory essay presents a definition of SACs and a conceptual framework for how different institutional features and contextual factors affect three proximal determinants of SACs' effectiveness, namely the quality of advice offered, the relevance of that advice, and its legitimacy.

An Overview of Systematic Reviews to Inform the Institutional Design of Scientific Advisory Committees.

The current lack of synthesized evidence for informing the design of scientific advisory committees (SACs) is surprising in light of the widespread use of SACs throughout decision-making processes. While existing research points to the importance of quality, relevance, and legitimacy for SACs' effectiveness, those planning SACs would benefit from efforts to systematically pinpoint optimal designs of these committees for maximal effectiveness. Search strategies are developed for seven electronic databases. Of the 1895 systematic reviews identified, six reviews meet the inclusion criteria: they report the results of systematic reviews that followed a clearly identified systematic methodology, examine factors related to the design of SACs, and involve processes in the natural or social sciences. These reviews collectively summarize 444 primary studies. Three of the six reviews look at the impacts of SAC size, two evaluate the influence of the committee's diversity, and half mention the importance of properly on-boarding new members. The goal is to identify recurring themes to understand the specific institutional features that optimize the usefulness of SACs. In turn, this overview of systematic reviews aims to contribute to a growing body of literature on how SACs should be designed to maximize their effectiveness and helpfulness for decision-making.

What Can Be Learned from Experience with Scientific Advisory Committees in the Field of International Environmental Politics?

Scientific advisory committees (SACs) are a critically important part of global environmental policy. This commentary reviews the role of SACs in six global and regional environmental regimes, defined here as the set of rules, norms, and procedures that are developed by states and international organizations out of their common concerns and used to organize common activities. First, SACs play a critical role in putting issues on the political agenda and the creation of an overarching regime. Second, the effectiveness of a given SAC and the associated regime is highly variable. Third, there is also considerable variation in the extent to which the regime is driven by an overarching scientific consensus, for example, high in the case of climate change, lower in the case of whaling. Fourth, the role of science in a given regime is also a function of whether the problem being addressed is relatively benign or more malign, that is to say, marked by deep political disagreements (i.e., climate change). Finally, the cases examined here suggest that the institutional design of the SAC matters and can influence the overall effectiveness of the SAC and by extension, the regime, but it is seldom decisive.

Systems Thinking as a Framework for Analyzing Commercial Determinants of Health.

Policy Points: Worldwide, more than 70% of all deaths are attributable to noncommunicable diseases (NCDs), nearly half of which are premature and apply to individuals of working age. Although such deaths are largely preventable, effective solutions continue to elude the public health community. One reason is the considerable influence of the "commercial determinants of health": NCDs are the product of a system that includes powerful corporate actors, who are often involved in public health policymaking. This article shows how a complex systems perspective may be used to analyze the commercial determinants of NCDs, and it explains how this can help with (1) conceptualizing the problem of NCDs and (2) developing effective policy interventions. CONTEXT: The high burden of noncommunicable diseases (NCDs) is politically salient and eminently preventable. However, effective solutions largely continue to elude the public health community. Two pressing issues heighten this challenge: the first is the public health community's narrow approach to addressing NCDs, and the second is the involvement of corporate actors in policymaking. While NCDs are often conceptualized in terms of individual-level risk factors, we argue that they should be reframed as products of a complex system. This article explores the value of a systems approach to understanding NCDs as an emergent property of a complex system, with a focus on commercial actors. METHODS: Drawing on Donella Meadows's systems thinking framework, this article examines how a systems perspective may be used to analyze the commercial determinants of NCDs and, specifically, how unhealthy commodity industries influence public health policy. FINDINGS: Unhealthy commodity industries actively design and shape the NCD policy system, intervene at different levels of the system to gain agency over policy and politics, and legitimize their presence in public health policy decisions. CONCLUSIONS: It should be possible to apply the principles of systems thinking to other complex public health issues, not just NCDs. Such an approach should be tested and refined for other complex public health challenges.

Contested roles of Canada's Chief Medical Officers of Health.

The roles and responsibilities of Canada's Chief Medical Officers of Health (CMOHs) are contested. On the one hand, they are senior public servants who confidentially advise government on public health matters and manage the implementation of government priorities. On the other hand, CMOHs are perceived as independent communicators and advocates for public health. This article analyzes public health legislation across Canada that governs the CMOH role. Our legal analysis reveals that the presence and degree of advisory, communication, and management roles for the CMOH vary considerably across the country. In many jurisdictions, the power and authority of the CMOH is not clearly defined in legislation. This creates great potential for confusion and conflict, particularly with respect to CMOHs' authority to act as public health advocates. We call on governments to clarify their preferences when it comes to the CMOH role and either amend the relevant statute or otherwise find ways to clarify the mandate of their CMOHs.

Why and How Political Science Can Contribute to Public Health? Proposals for Collaborative Research Avenues.

Written by a group of political science researchers, this commentary focuses on the contributions of political science to public health and proposes research avenues to increase those contributions. Despite progress, the links between researchers from these two fields develop only slowly. Divergences between the approach of political science to public policy and the expectations that public health can have about the role of political science, are often seen as an obstacle to collaboration between experts in these two areas. Thus, promising and practical research avenues are proposed along with strategies to strengthen and develop them. Considering the interdisciplinary and intersectoral nature of population health, it is important to create a critical mass of researchers interested in the health of populations and in healthy public policy that can thrive working at the junction of political science and public health.

Policy Capacity Meets Politics: Comment on "Health Reform Requires Policy Capacity".

It is difficult to disagree with the general argument that successful health reform requires a significant degree of policy capacity or that all players in the policy game need to move beyond self-interested advocacy. However, an overly broad definition of policy capacity is a problem. More important perhaps, health reform inevitably requires not just policy capacity but political leadership and compromise.

Beyond the usual suspects: using political science to enhance public health policy making.

That public health policy and practice should be evidence based is a seemingly uncontroversial claim. Yet governments and citizens routinely reject the best available evidence and prefer policies that reflect other considerations and concerns. The most common explanations of this paradox emphasise scientific disagreement, the power of 'politics', or the belief that scientists and policymakers live in two separate communities that do not communicate. However, another explanation may lie in the limits of the very notion of evidence-based policy making. In fact, the social science discipline of political science offers a rich body of theory and empirical evidence to explain the apparent gap between evidence and policy. This essay introduces this literature with a particular emphasis on a recent book by Katherine Smith, Beyond evidence-based policy in public health: the interplay of ideas. As the title suggests, Smith argues that what matters for public health policy is less scientific evidence and much more a more complex set of ideas. Based on detailed case studies of UK tobacco and health inequality policy, Smith offers a richly textured alternative account of what matters for policy making. This excellent book is part of a small but growing body of political science research on public health policy that draws on contemporary theories of policy change and governance more generally. This essay provides a window on this research, describes some examples, but emphasises that public health scholars and practitioners too often retain a narrow if not naive view of the policy-making process.

Taking power, politics, and policy problems seriously: the limits of knowledge translation for urban health research.

Knowledge translation (KT) is a growing movement in clinical and health services research, aimed to help make research more relevant and to move research into practice and policy. This paper examines the conventional model of policy change presented in KT and assesses its applicability for increasing the impact of urban health research on urban health policy. In general, KT conceptualizes research utilization in terms of the technical implementation of scientific findings, on the part of individual decision-makers who can be "targeted" for a KT intervention, in a context that is absent of political interests. However, complex urban health problems and interventions infrequently resemble this single decision, single decision-maker model posited by KT. In order to clarify the conditions under which urban health research is more likely or not to have an influence on public policy development, we propose to supplement the conventional model with three concepts drawn from the social science: policy stages, policy networks, and a discourse analysis approach for theorizing power in policy-making.

Public health understandings of policy and power: lessons from INSITE.

Drug addiction is a major public health problem, one that is most acutely felt in major cities around the globe. Harm reduction and safe injection sites are an attempt to address this problem and are at the cutting edge of public health policy and practice. One of the most studied safe injection sites is INSITE located in Vancouver, British Columbia. Using INSITE as a case study, this paper argues that knowledge translation offers a limited framework for understanding the development of public health policy. This paper also argues that the experience of INSITE suggests that science and social justice, the meta-ideas that lie at the core of the public health enterprise, are an inadequate basis for a theory of public health policy making. However, on a more positive note, INSITE also shows the value of concepts drawn from the ways in which political science analyzes the policy process.
