Use of evidence to support healthy public policy: a policy effectiveness-feasibility loop

Why is health improvement policy so difficult to secure?

Many governments seek to improve population health, and some seek to reduce health inequalities. Yet, there remains a large gap between their policy statements and actual outcomes. Perennial questions in public health research include: why is this gap so large, why does it endure, and what can be done to close it? This essay uses political science and policy studies insights to address these questions, focusing on the distinctive issues that relate to (1) broad aims like 'prevention', (2) specific strategies for health improvement, or (3) new events. On the one hand, the idea of 'prevention' has widespread appeal, when governments think they can save money or reduce inequalities by preventing problems happening or worsening. While health protection seeks to inoculate populations against communicable diseases, health improvement strategies, including 'Health in All Policies' (HiAP), primarily address non-communicable diseases (NCDs). Further, the coronavirus disease 2019 (COVID-19) pandemic highlights the unequal spread of ill health, showing that preventive health ideas should be at the core of policy. On the other hand, there is a large gap between rhetorical and substantive commitment to prevention, a continuous HiAP implementation gap, and a tendency for COVID-19 health protection to overshadow health improvement. Explaining each problem clearly helps to identify the factors that generally undermine prevention policies and those specific to more detailed strategies like HiAP or events like COVID-19. We do not prioritise leadership or 'political will' as the policymaking problem. Instead, we identify the systemic factors that apply to even the most sincere, competent, and energetic policymakers. Health improvement policy is typically undermined by a lack of: clarity about what prevention means in practice; congruity between the prevention agenda (emphasising the need for major change to policy and policymaking) and routine government business; and, capacity to overcome obstacles to policy change.

The future of public health policymaking after COVID-19: a qualitative systematic review of lessons from Health in All Policies

Background: 'Health in All Policies' (HiAP) describes the pursuit of health equity. It has five main elements: treat health as a human right; identify evidence of the 'social determinants' of health inequalities, recognise that most powers to affect health are not held by health departments, promote intersectoral policymaking and collaboration inside and outside of government, and generate political will. Studies describe its potential but bemoan a major implementation gap. Some HiAP scholars learn from policymaking research how to understand this gap, but the use of policy theories is patchy. In that context, our guiding research question is: How does HiAP research use policy theory to understand policymaking? It allows us to zoom-out to survey the field and zoom-in to identify: the assumed and actual causes of policy change, and transferable lessons to HiAP scholars and advocates. Methods: Our qualitative systematic review (two phases, 2018 and 2020) identified 4972 HiAP articles. Of these, 113 journal articles (research and commentary) provide a non-trivial reference to policymaking (at least one reference to a policymaking concept). We use the 113 articles to produce a general HiAP narrative and explore how the relatively theory-informed articles enhance it. Results: Most articles focus on policy analysis (identifying policy problems and solutions) rather than policy theory (explaining policymaking dynamics). They report a disappointing gap between HiAP expectations and policy outcomes. Theory-informed articles contribute to a HiAP playbook to close that gap or a programme theory to design and evaluate HiAP in new ways.   Conclusions: Few HiAP articles use policy theories for their intended purpose. Policy theories provide lessons to aid critical reflection on power, political dilemmas, and policymaking context. HiAP scholars seek more instrumental lessons, potentially at the cost of effective advocacy and research.

The legal feasibility of adopting a sugar-sweetened beverage tax in seven sub-Saharan African countries

Background: A number of countries have adopted sugar-sweetened beverage taxes to prevent non-communicable diseases but there is variance in the structures and rates of the taxes. As interventions, sugar-sweetened beverage taxes could be cost-effective but must be compliant with existing legal and taxation systems.Objectives: To assess the legal feasibility of introducing or strengthening taxation laws related to sugar-sweetened beverages, for prevention of non-communicable diseases in seven countries: Botswana, Kenya, Namibia, Rwanda, Tanzania, Uganda and Zambia.Methods: We assessed the legal feasibility of adopting four types of sugar-sweetened beverage tax formulations in each of the seven countries, using the novel FELIP framework. We conducted a desk-based review of the legal system related to sugar-sweetened beverage taxation and assessed the barriers to, and facilitators and legal feasibility of, introducing each of the selected formulations by considering the existing laws, laws related to impacted sectors, legal infrastructure, and processes involved in adopting laws.Results: Six countries had legal mandates to prevent non-communicable diseases and protect the health of citizens. As of 2019, all countries had excise tax legislation. Five countries levied excise taxes on all soft drinks, but most did not exclusively target sugar-sweetened beverages, and taxation rates were well below the World Health Organization's recommended 20%. In Uganda and Kenya, agricultural or HIV-related levies offered alternative mechanisms to disincentivise consumption of sugar-sweetened beverages without the introduction of new taxes. Nutrition-labelling laws in all countries made it feasible to adopt taxes linked to the sugar content of beverages, but there were lacunas in existing infrastructure for more sophisticated taxation structures.Conclusion: Sugar-sweetened beverage taxes are legally feasible in all seven countries Existing laws provide a means to implement taxes as a public health intervention.

Management of diabetics. Comparative study of two contrasting health structures

BACKGROUND

The proportion of total Tunisian with Diabetes reached 15.5% in 2016. The objective of this study was to analyze diabetic's management in contrasted health care settings.

METHODS

Mixed methodology (quantitative and qualitative) with explanatory design was used in contrasted health care structures (a primary health center (PHC) and the National Institute of Nutrition and Food Technologies (INNTA)). Interviews with health providers and patients were than condcuted in both centers to explain quantitative findings.

RESULTS

Quality of care assessement was performed among 100 patients in the PHC and 96 in the hospital. Glycemic control was reached in less than 30 % of the cases in both centers. Although clinical evaluation was better in the PHC, conducting ECGs, measuring of HbA1c  and  LDL-Ch were far from being optimal. The qualitative study did supply some hypotheses explaining these gaps: treatments shortage and lack of laboratory assessments specifically pointed in PHC settings, potentially lower its attractiveness, thus compounding overcrowding and stressful working conditions in hospitals. These last points as well as poor communication and overloaded clinics in hospital were major sources of providers and patient dissatisfaction.

CONCLUSION

This study made it clear that primary health care is a cornerstone in diabetes management. However, it is crucial to strengthen primary health care centers by operational technical support (laboratory equipements and quality information system) as well building capacities of health professionals in information, education and communication.

Ottawa charter framework as a guide for type 2 diabetes prevention and control in Iran

The growth of T2DM in Iran is predicted to be even greater than the global trend. So a new public health movement to effectively prevent and manage T2DM is required more than ever. The solution has lain in the heart of the Ottawa Charter, the first international conference on health promotion more than 30 years ago. The charter contains five useful actions to facilitate the process of diseases prevention and control: 1) building healthy public policy, 2) creating supportive environments, 3) strengthening community action, 4) developing personal skills, and 5) reorienting health care services toward promotion of health. The charter articulates health in all policies and their frameworks. The aim of this review is to examine how the five actions have been implemented in Iran and can serve as a guide to prevent and control diabetes. Several national case studies will be examined to illustrate the challenges facing Iran's health system. It enables the identification and sharing of best practice between countries.

Dementia Primary Prevention Policies and Strategies and Their Local Implementation: A Scoping Review Using England as a Case Study

BACKGROUND

Understanding the policy context and how policy is implemented at the local and clinical level is an important precursor to developing preventive strategies focusing on dementia risk reduction in primary healthcare settings.

OBJECTIVE

Using England as a case study, we review policies and strategies relevant to dementia prevention from the national to local level and how these are translated into primary healthcare services.

METHODS

We conducted a scoping review covering: 1) identification of national, regional, and local policies and strategies that include dementia prevention; 2) identification of national guidelines for implementing dementia prevention at the clinical level; and 3) evaluation of the implementation of these at the clinical level.

RESULTS

Dementia prevention is addressed in national policy, and this filters through to regional and local levels. Focus on dementia prevention is limited and variable. Reference to modifiable risk factors is associated with other non-communicable diseases, placing less emphasis on factors more dementia specific. Evidence of implementation of dementia prevention policies at the clinical level is limited and inconsistent. Available evidence suggests messages about dementia prevention may best be delivered through primary healthcare services such as the National Health Service (NHS) Health Check.

CONCLUSION

The limitations identified in this review could be addressed through development of a national policy focused specifically on dementia prevention. This could provide a platform for increasing knowledge and understanding among the general population and healthcare professionals. It would be important for such a policy to cover the full range of modifiable risk factors relevant to dementia.

National action plan for non-communicable diseases prevention and control in Iran; a response to emerging epidemic

Emerging Non-communicable diseases burden move United Nation to call for 25% reduction by 2025 in premature mortality from non-communicable diseases (NCDs). The World Health Organization (WHO) developed global action plan for prevention and control NCDs, but the countries' contexts, priorities, and health care system might be different. Therefore, WHO expects from countries to meet national commitments to achieve the 25 by 25 goal through adapted targets and action plan. In this regards, sustainable high-level political statement plays a key role in rules and regulation support, and multi-sectoral collaborations to NCDs' prevention and control by considering the sustainable development goals and universal health coverage factors. Therefore, Iran established the national authority's structure as Iranian Non Communicable Diseases Committee (INCDC) and developed NCDs' national action plan through multi-sectoral approach and collaboration researchers and policy makers. Translation Iran's expertise could be benefit to mobilizing leadership in other countries for practical action to save the millions of peoples.

Engagement of Sectors Other than Health in Integrated Health Governance, Policy, and Action

Health is created largely outside the health sector. Engagement in health governance, policy, and intervention development and implementation by sectors other than health is therefore important. Recent calls for building and implementing Health in All Policies, and continued arguments for intersectoral action, may strengthen the potential that other sectors have for health. This review clarifies the conceptual foundations for integral health governance, policy, and action, delineates the different sectors and their possible engagement, and provides an overview of a continuum of methods of engagement with other sectors to secure integration. This continuum ranges from institutional (re)design to value-based narratives. Depending on the lens applied, different elements can be identified within the continuum. This review is built on insights from political science, leadership studies, public health, empirical Health in All Policy research, knowledge and evidence nexus approaches, and community perspectives. Successful integration of health governance, policy, and action depends on integration of the elements on the continuum.

The role of the Sheffield model on the minimum unit pricing of alcohol debate: the importance of a rhetorical perspective

The minimum unit pricing (MUP) alcohol policy debate has been informed by the Sheffield model, a study which predicts impacts of different alcohol pricing policies. This paper explores the Sheffield model's influences on the policy debate by drawing on 36 semi-structured interviews with policy actors who were involved in the policy debate. Although commissioned by policy makers, the model's influence has been far broader than suggested by views of 'rational' policy making. While findings from the Sheffield model have been used in instrumental ways, they have arguably been more important in helping debate competing values underpinning policy goals.

A survey of knowledge-to-action pathways of aging policies and programs in the Arab region: the role of institutional arrangements

BACKGROUND

While population aging challenges Arab governments to ensure well-being in old age, knowledge translation is gaining support worldwide in evidence-based policymaking and service provision. This study examines the status of existing knowledge translation efforts of aging-related research in Arab countries and evaluates the additional role that institutional arrangements (such as ministry departments, national committees, etc.) play in the relationship between knowledge creation and social and health policies and programs.

METHODS

Data were triangulated from two regional surveys and a supplementary desk review of academic, civil society, ministry, and UN documents. Using a set of indicators, standardized summative indices (out of 100) were generated for five constructs, namely knowledge creation, institutional arrangements, knowledge translation, and health and social policies and programs. Correlations were assessed using Spearman's rank correlation (r s), and bootstrap multiple linear regression models were used.

RESULTS

Arab countries scored highest on the institutional arrangements index (median = 69.5), followed by the knowledge creation index (median = 45.9), and lowest on the knowledge translation index (median = 30.2). Both institutional arrangements and knowledge creation significantly correlated with social and health policies and programs. However, when adjusted for knowledge translation, only institutional arrangements retained a significant association with both outcomes (r s = 0.63, p value =0.009 and r s = 0.69, p value =0.01, respectively). Adjusting for institutional arrangements and knowledge creation, the association of knowledge translation with social and health policies and programs was attenuated and non-significant (r s = 0.08, p value =0.671 and r s = 0.12, p value =0.634, respectively).

CONCLUSIONS

There are two key messages from this study. Firstly, institutional arrangements play a central role in aging social and health policy and program development in the Arab region. Secondly, knowledge translation paradigms in Arab countries may be deficient in factors pertinent for promoting evidence-based decision-making and policy-relevant research. These findings call for the need of strengthening institutional arrangements on aging and for promoting knowledge production that meets policy-relevant priorities.

Simple calculator to estimate the medical cost of diabetes in sub-Saharan Africa

AIM: To design a medical cost calculator and show that diabetes care is beyond reach of the majority particularly patients with complications.

METHODS: Out-of-pocket expenditures of patients for medical treatment of type-2 diabetes were estimated based on price data collected in Benin, Burkina Faso, Guinea and Mali. A detailed protocol for realistic medical care of diabetes and its complications in the African context was defined. Care components were based on existing guidelines, published data and clinical experience. Prices were obtained in public and private health facilities. The cost calculator used Excel. The cost for basic management of uncomplicated diabetes was calculated per person and per year. Incremental costs were also computed per annum for chronic complications and per episode for acute complications.

RESULTS: Wide variations of estimated care costs were observed among countries and between the public and private healthcare system. The minimum estimated cost for the treatment of uncomplicated diabetes (in the public sector) would amount to 21%-34% of the country’s gross national income per capita, 26%-47% in the presence of retinopathy, and above 70% for nephropathy, the most expensive complication.

CONCLUSION: The study provided objective evidence for the exorbitant medical cost of diabetes considering that no medical insurance is available in the study countries. Although the calculator only estimates the cost of inaction, it is innovative and of interest for several stakeholders.

Interplay among patient empowerment and clinical and person-centered outcomes in type 2 diabetes. The BENCH-D study

OBJECTIVE

We evaluated empowerment in T2DM and identified its correlates.

METHODS

A sample of individuals self-administered the Diabetes Empowerment Scale-Short Form (DES-SF) and other 9 validated instruments (person-centered outcomes). Correlates of DES-SF were identified through univariate and multivariate analyses. For person-centered outcomes, ORs express the likelihood of being in upper quartile of DES-SF (Q4) by 5 units of the scale.

RESULTS

Overall, 2390 individuals were involved. Individuals in Q4 were younger, more often males, had higher levels of school education, lower HbA1c levels and prevalence of complications as compared to individuals in the other quartiles. The likelihood of being in Q4 was directly associated with higher selfreported self-monitoring of blood glucose (SDSCA6-SMBG) (OR=1.09; 95% CI: 1.03-1.15), higher satisfaction with diabetes treatment (GSDT) (OR=1.15; 95% CI: 1.07-1.25), perceived quality of chronic illness care and patient support (PACIC-SF) (OR=1.23; 95% CI: 1.16-1.31), and better person-centered communication (HCC-SF) (OR=1.10; 95% CI: 1.01-1.19) and inversely associated with diabetes-related distress (PAID-5) (OR=0.95; 95% CI: 0.92-0.98). Adjusted DES-SF mean scores ranged between centers from 69.8 to 93.6 (intra-class correlation=0.10; p<0.0001).

CONCLUSIONS

Empowerment was associated with better glycemic control, psychosocial functioning and perceived access to person-centered chronic illness care. Practice of diabetes center plays a specific role.

PRACTICE IMPLICATIONS

DES-SF represents a process and outcome indicator in the practice of diabetes centers.

The Health Impact Fund: how might it work for novel anticoagulants in atrial fibrillation?

Cardiovascular diseases represent the greatest burden of global disease. Spending on cardiovascular diseases is higher than for other diseases, with the majority being spent on drugs. Therefore, these drugs and these diseases are hugely important to health systems, society, and pharmaceutical companies. The Health Impact Fund represents a new mechanism by which pharmaceutical innovators would be rewarded on the basis of the health impact of their new drugs. This review illustrates the concept of the Health Impact Fund using the example of novel anticoagulants for prevention of stroke and thromboembolism in atrial fibrillation. By considering existing data and the current situation for novel anticoagulants, we suggest that epidemiologic data and modeling techniques can be used to predict future trends in disease and the health impact of new drugs. The Health Impact Fund may offer potential benefits to pharmaceutical companies, patients, and governments and warrants proper investigation.

Health system challenges for the management of cardiovascular disease and diabetes: an empirical qualitative study from Syria

OBJECTIVES

To explore through empirical qualitative data health system barriers to effective management of cardiovascular disease and diabetes in Syria before the crisis, and how such analysis can inform the building of a post-crisis system.

METHODS

Data were collected through document review, semi-structured key informant interviews, and fieldwork in clinics.

RESULTS

Institutional commitment to address the increasing burden of CVD and diabetes in Syria was limited and uncoordinated. Challenges included an increasingly split healthcare system, with private provision for those who could afford it, and a residual state health sector for the majority. Public trust in the system had been declining.

CONCLUSIONS

We conclude that lack of effective management of CVD and diabetes indicated weaknesses of the state and its retracting role in providing effective healthcare. Such weaknesses that existed before the crisis are now compounded by new challenges resulting from wide destruction of the health system due to the ongoing war. The rebuilding of post-conflict heath care system may benefit from insights into the structural problems of the pre-crisis system.

Living with diabetes and hypertension in Tunisia: popular perspectives on biomedical treatment

OBJECTIVES

The growing prevalence of non-communicable diseases across the Middle East and North Africa poses major challenges for underfunded health services. This article presents data on the perspectives of ordinary Tunisians who are coping with two of these diseases--diabetes and hypertension--and who are obtaining treatment through Tunisian public health clinics. Little has been written to date on patient experiences of biomedical treatment in Maghreb countries.

METHODS

Based on qualitative methods and semi-structured interviews with 24 patients attending two clinics, one urban and one rural.

RESULTS

We examine popular aetiological beliefs, ideas about biomedical treatment and its implications, and comparative views on the benefits and drawbacks of treatment in both public and private clinics.

CONCLUSIONS

We highlight two main themes. One was nostalgia for a recent past when 'pure' and 'natural' food, 'proper' meals and less stressful lives meant less chronic illness, with demanding and costly treatment. The other concerned communication in the clinic, and the recurrent dismay patients felt at what they saw as the cursory attention and guidance they received from clinic staff in public facilities.

Priority setting for the prevention and control of cardiovascular diseases: multi-criteria decision analysis in four eastern Mediterranean countries

OBJECTIVES

To explore the feasibility of using a simple multi-criteria decision analysis method with policy makers/key stakeholders to prioritize cardiovascular disease (CVD) policies in four Mediterranean countries: Palestine, Syria, Tunisia and Turkey.

METHODS

A simple multi-criteria decision analysis (MCDA) method was piloted. A mixed methods study was used to identify a preliminary list of policy options in each country. These policies were rated by different policymakers/stakeholders against pre-identified criteria to generate a priority score for each policy and then rank the policies.

RESULTS

Twenty-five different policies were rated in the four countries to create a country-specific list of CVD prevention and control policies. The response rate was 100% in each country. The top policies were mostly population level interventions and health systems' level policies.

CONCLUSIONS

Successful collaboration between policy makers/stakeholders and researchers was established in this small pilot study. MCDA appeared to be feasible and effective. Future applications should aim to engage a larger, representative sample of policy makers, especially from outside the health sector. Weighting the selected criteria might also be assessed.

Comparison of type 2 diabetes prevalence estimates in Saudi Arabia from a validated Markov model against the International Diabetes Federation and other modelling studies

AIMS

To compare the estimates and projections of type 2 diabetes mellitus (T2DM) prevalence in Saudi Arabia from a validated Markov model against other modelling estimates, such as those produced by the International Diabetes Federation (IDF) Diabetes Atlas and the Global Burden of Disease (GBD) project.

METHODS

A discrete-state Markov model was developed and validated that integrates data on population, obesity and smoking prevalence trends in adult Saudis aged ≥25 years to estimate the trends in T2DM prevalence (annually from 1992 to 2022). The model was validated by comparing the age- and sex-specific prevalence estimates against a national survey conducted in 2005.

RESULTS

Prevalence estimates from this new Markov model were consistent with the 2005 national survey and very similar to the GBD study estimates. Prevalence in men and women in 2000 was estimated by the GBD model respectively at 17.5% and 17.7%, compared to 17.7% and 16.4% in this study. The IDF estimates of the total diabetes prevalence were considerably lower at 16.7% in 2011 and 20.8% in 2030, compared with 29.2% in 2011 and 44.1% in 2022 in this study.

CONCLUSION

In contrast to other modelling studies, both the Saudi IMPACT Diabetes Forecast Model and the GBD model directly incorporated the trends in obesity prevalence and/or body mass index (BMI) to inform T2DM prevalence estimates. It appears that such a direct incorporation of obesity trends in modelling studies results in higher estimates of the future prevalence of T2DM, at least in countries where obesity has been rapidly increasing.
