Generating Global Priority for Addressing Rheumatic Heart Disease: A Qualitative Policy Analysis

Factors shaping network emergence: A cross-country comparison of quality of care networks in Bangladesh, Ethiopia, Malawi, and Uganda

The Quality-of-Care Network (QCN) was conceptualized by the World Health Organization (WHO) and other global partners to facilitate learning on and improve quality of care for maternal and newborn health within and across low and middle-income countries. However, there was significant variance in the speed and extent to which QCN formed in the involved countries. This paper investigates the factors that shaped QCN's differential emergence in Bangladesh, Ethiopia, Malawi, and Uganda. Drawing on network scholarship, we conducted a replicated case study of the four country cases and triangulated several sources of data, including a document review, observations of national-level and district level meetings, and key informant interviews in each country and at the global level. Thematic coding was performed in NVivo 12. We find that QCN emerged most quickly and robustly in Bangladesh, followed by Ethiopia, then Uganda, and slowest and with least institutionalization in Malawi. Factors connected to the policy environment and network features explained variance in network emergence. With respect to the policy environment, pre-existing resources and initiatives dedicated to maternal and newborn health and quality improvement, strong data and health system capacity, and national commitment to advancing on synergistic goals were crucial drivers to QCN's emergence. With respect to the features of the network itself, the embedding of QCN leadership in powerful agencies with pre-existing coordination structures and trusting relationships with key stakeholders, inclusive network membership, and effective individual national and local leadership were also crucial in explaining QCN's speed and quality of emergence across countries. Studying QCN emergence provides critical insights as to why well-intentioned top-down global health networks may not materialize in some country contexts and have relatively quick uptake in others, and has implications for a network's perceived legitimacy and ultimate effectiveness in producing stated objectives.

Comparing priority received by global health issues: a measurement framework applied to tuberculosis, malaria, diarrhoeal diseases and dengue fever

INTRODUCTION

The relative priority received by issues in global health agendas is subjected to impressionistic claims in the absence of objective methods of assessment of priority. To build an approach for conducting structured assessments of comparative priority health issues receive, we expand the public arenas model (2021) and offer a framework for future assessments of health issue priority in global and national health agendas.

METHODS

We aimed to develop a more comprehensive set of measures for conducting multiyear priority comparisons of health issues in six agenda-setting arenas by identifying possible measures and data sources, selecting indicators based on feasibility and comparability of measures and gathering the data on selected indicators. We applied these measures to four communicable diseases-tuberculosis (TB), malaria, diarrhoeal diseases and dengue fever-given their differing impressionistic claims of priority. Where possible, we analysed the annual and/or 5-year trends from 2000 through 2022.

RESULTS

We observed that TB and malaria received the highest priority for most periods in the past two decades in most arenas. However, a stagnation in development funding for these two conditions over the last 8-10 years may have fuelled the neglect claims. Despite having a higher disease burden, diarrhoea has been slipping in global priority with reduced spending, fewer clinical trials and stagnating publications. Dengue remains a low-priority condition but has witnessed a sharp rise in attention from the pharmaceutical industry.

DISCUSSIONS

We expanded the arenas model by including a transnational arena (international representation) and additional measurements for various arenas. This analysis presents an approach to enable comparative trend analysis of the markers of agenda status over a multiyear period. More such analyses can bring much-desired objectivity in understanding how attention to global or national health issues changes over time in different arenas, potentiating a more equitable allocation of resources.

Barriers to Access to Cardiac Surgery: Canadian Situation and Global Context

Cardiovascular disease is the leading cause of morbidity and mortality worldwide. Cardiovascular care spans primary, secondary, and tertiary prevention and care, whereby tertiary care is particularly prone to disparities in care. Challenges in access to care especially affect low- and middle-income countries (LMICs), however, multiple barriers also exist and persist across high-income countries. Canada is lauded for its universal health coverage but is faced with health care system challenges and substantial geographic barriers. Canada possesses 203 active cardiac surgeons, or 5.02 per million population, ranging from 3.70 per million in Newfoundland and Labrador to 7.48 in Nova Scotia. As such, Canada possesses fewer cardiac surgeons per million population than the average among high-income countries (7.15 per million), albeit more than the global average (1.64 per million) and far higher than the low-income country average (0.04 per million). In Canada, adult cardiac surgeons are active across 32 cardiac centres, representing 0.79 cardiac centres per million population, which is just above the global average (0.73 per million). In addition to centre and workforce variations, barriers to care exist in the form of waiting times, sociodemographic characteristics, insufficient virtual care infrastructure and electronic health record interoperability, and health care governance fragmentation. Meanwhile, Canada has highly favourable surgical outcomes, well established postacute cardiac care infrastructure, considerable spending on health, robust health administrative data, and effective health technology assessment agencies, which provides a foundation for continued improvements in care. In this narrative review, we describe successes and challenges surrounding access to cardiac surgery in Canada and globally.

Viral cardiovascular surgical diseases: global burdens, challenges and opportunities

Globally, more than one billion people are vulnerable to neglected tropical diseases, many of which have viral origins and cardiovascular implications. Access to cardiovascular care is limited in countries where these conditions are endemic. Six billion people lack access to safe, timely and affordable cardiac surgical care, whereby over 100 countries and territories lack a single cardiac surgeon. Moreover, while clinically unique, the surgical consequences of neglected cardiovascular diseases with viral origins have been poorly described in the current literature. This review provides an overview of the global burden of viral cardiovascular disease, describes access to cardiac surgical care in regions where these conditions are endemic, and further highlights surgical consequences and considerations to manage patients requiring cardiac surgical care.

Redefining global cardiac surgery through an intersectionality lens

Although cardiovascular diseases are the leading cause of morbidity and mortality worldwide, six billion people lack access to safe, timely and affordable cardiac surgical care when needed. The burden of cardiovascular disease and disparities in access to care vary widely based on sociodemographic characteristics, including but not limited to geography, sex, gender, race, ethnicity, indigeneity, socioeconomic status and age. To date, the majority of cardiovascular, global health and global surgical research has lacked intersectionality lenses and methodologies to better understand access to care at the intersection of multiple identities and traditions. As such, global (cardiac) surgical definitions and health system interventions have been rooted in reductionism, focusing, at most, on singular sociodemographic characteristics. In this article, we evaluate barriers in global access to cardiac surgery based on existing intersectionality themes and literature. We further examine intersectionality methodologies to study access to cardiovascular care and cardiac surgery and seek to redefine the definition of 'global cardiac surgery' through an intersectionality lens.

The role of echocardiographic screening in reducing the burden of rheumatic heart disease in Latin America

The objectives of this article are to reflect on the rationale behind the use of echocardiographic screening for rheumatic heart disease and to provide key recommendations about steps needed to implement and improve echocardiographic screening programs in Latin America. Rheumatic heart disease remains a public health problem affecting mainly low-income and lower-middle-income countries and populations. Latin America is an area with economic inequalities, and the epidemiology of rheumatic heart disease remains largely unknown. Echocardiographic screening is useful for updating the epidemiology and providing early diagnosis of the disease. We discuss different approaches used in successful echocardiographic screening programs worldwide and in Latin America. We then identify the key elements needed to establish successful echocardiographic screening programs in Latin America, including increased awareness and involvement from multiple sectors (e.g. the community, health care professionals, scientific organizations and public health entities), identification of areas in need, development of a plan and structure that include different screening approaches, and how to ensure appropriate follow up for those who screen positive.

Global Access to Cardiac Surgery Centers: Distribution, Disparities, and Targets

BACKGROUND

Global data on cardiac surgery centers are outdated and survey-based. In 1995, there were 0.7 centers per million population, ranging from one per 120,000 in North America to one per 33 million in sub-Saharan Africa. This study analyzes the contemporary distribution of cardiac surgery centers and proposes targets relative to countries' cardiovascular disease (CVD) burdens.

METHODS

Medical databases, gray literature, and governmental reports were used to identify the most recent post-2010 data that describe the number of centers performing cardiac surgery in each nation. The 2019 Institute for Health Metrics and Evaluation Global Burden of Disease Results Tool provided national CVD burdens. One-third of the CVD burden was assumed to be surgical. Center targets were proposed as the average or half of the average of centers per million surgical CVD patients in high-income countries.

RESULTS

5,111 cardiac surgery centers were identified across 230 nations and territories with available data, equaling 0.73 centers per million population. The median (interquartile range) number of centers ranged from 0 (0-0.06) per million in low-income countries to 0.75 (0-1.44) in high-income countries. Targets were 612.2 (optimistic) or 306.1 (conservative) centers per million surgical CVD incidence. In 2019, low-income, lower-middle-income, and upper-middle-income countries possessed 34.8, 149.0, and 271.9 centers per million surgical CVD incidence.

CONCLUSION

Little progress has been made to increase cardiac surgery centers per population despite growing CVD burdens. Today's global cardiac surgical capacity remains insufficient, disproportionately affecting the world's poorest regions.

Prioritizing rehabilitation in low- and middle-income country national health systems: a qualitative thematic synthesis and development of a policy framework

BACKGROUND

There is a large and growing unmet need for rehabilitation - a diverse category of services that aim to improve functioning across the life course - particularly in low- and middle-income countries. Yet despite urgent calls to increase political commitment, many low- and middle-income country governments have dedicated little attention to expanding rehabilitation services. Existing policy scholarship explains how and why health issues reach the policy agenda and offers applicable evidence to advance access to physical, medical, psychosocial, and other types of rehabilitation services. Drawing from this scholarship and empirical data on rehabilitation, this paper proposes a policy framework to understand national-level prioritization of rehabilitation in low- and middle-income countries.

METHODS

We conducted key informant interviews with rehabilitation stakeholders in 47 countries, complemented by a purposeful review of peer-reviewed and gray literature to achieve thematic saturation. We analyzed the data abductively using a thematic synthesis methodology. Rehabilitation-specific findings were triangulated with policy theory and empirical case studies on the prioritization of other health issues to develop the framework.

RESULTS

The novel policy framework includes three components which shape the prioritization of rehabilitation on low- and middle-income countries' national government's health agendas. First, rehabilitation lacks a consistent problem definition, undermining the development of consensus-driven solutions which could advance the issue on policy agendas. Second, governance arrangements are fragmented within and across government ministries, between the government and its citizens, and across national and transnational actors engaged in rehabilitation service provision. Third, national legacies - particularly from civil conflict - and weaknesses in the existing health system influences both rehabilitation needs and implementation feasibility.

CONCLUSIONS

This framework can support stakeholders in identifying the key components impeding prioritization for rehabilitation across different national contexts. This is a crucial step for ultimately better advancing the issue on national policy agendas and improving equity in access to rehabilitation services.

Rheumatic Heart Disease Is a Neglected Disease Relative to Its Burden Worldwide: Findings From Global Burden of Disease 2019

Background

Rheumatic heart disease (RHD) takes a heavy toll in low‐ and middle‐income countries. We aimed to present worldwide estimates for the burden of the RHD during 1990 to 2019 using the GBD (Global Burden of Disease) study.

Methods and Results

Sociodemographic index (SDI) and age‐period‐cohort analysis were used to assess inequity. The age‐standardized death, disability‐adjusted life years, incidence, and prevalence rates of RHD were 3.9 (95% uncertainty interval, 3.3–4.3), 132.9 (95% uncertainty interval, 115.0–150.3), 37.4 (28.6–46.7), and 513.7 (405.0–636.3) per 100 000 in 2019, respectively. The age‐standardized incidence and prevalence rates increased by 14.4% and 13.8%, respectively. However, disability‐adjusted life years and death rates decreased by 53.1% and 56.9%, respectively. South Asia superregion had the highest age‐standardized disability‐adjusted life years and deaths. Sub‐Saharan Africa had the highest age‐standardized incidence and prevalence rates. There was a steep decline in RHD burden among higher‐SDI countries. However, only age‐standardized deaths and disability‐adjusted life years rates decreased in lower‐SDI countries. The age‐standardized years of life lost and years lived with disability rates for RHD significantly declined as countries' SDI increased. The coefficients of birth cohort effect on the incidence of RHD showed an increasing trend from 1960 to 1964 to 2015 to 2019; however, the birth cohort effect on deaths attributable to RHD showed unfailingly decreasing trends from 1910 to 1914 to 2015 to 2019.

Conclusions

There was a divergence in the burden of RHD among countries based on SDI levels, which calls for including RHD in global assistance and funding. Indeed, many countries are still dealing with an unfinished infectious disease agenda, and there is an urgency to act now to prevent an increase in future RHD burden.

Rheumatic heart disease prevalence in Namibia: a retrospective review of surveillance registers

BACKGROUND

Rheumatic heart disease (RHD) is the most commonly acquired heart disease in children and young people in low and middle-income settings. Fragile health systems and scarcity of data persist to limit the understanding of the relative burden of this disease. The aims of this study were to estimate the prevalence of RHD and to assess the RHD-related health care systems in Namibia.

METHODS

Data was retrieved from outpatient and inpatient registers for all patients diagnosed and treated for RHD between January 2010 to December 2020. We used descriptive statistics to estimate the prevalence of RHD. Key observations and engagement with local cardiac clinicians and patients helped to identify key areas of improvement in the systems.

RESULTS

The outpatient register covered 0.032% of the adult Namibian population and combined with the cumulative incidence from the inpatient register we predict the prevalence of clinically diagnosed RHD to be between 0.05% and 0.10% in Namibia. Young people (< 18 years old) are most affected (72%), and most cases are from the north-eastern regions. Mitral heart valve impairment (58%) was the most common among patients. We identified weaknesses in care systems i.e., lack of patient unique identifiers, missing data, and clinic-based prevention activities.

CONCLUSION

The prevalence of RHD is expected to be lower than previously reported. It will be valuable to investigate latent RHD and patient follow-ups for better estimates of the true burden of disease. Surveillance systems needs improvements to enhance data quality. Plans for expansions of the clinic-based interventions must adopt the "Awareness Surveillance Advocacy Prevention" framework supported by relevant resolutions by the WHO.

A systematic framework for prioritising burden of disease data required for vaccine development and implementation: the case for group A streptococcal diseases

Vaccine development and implementation decisions need to be guided by accurate and robust burden of disease data. We developed an innovative systematic framework outlining the properties of such data that are needed to advance vaccine development and evaluation, and prioritize research and surveillance activities. We focus on 4 objectives—advocacy, regulatory oversight and licensure, policy and post-licensure evaluation, and post-licensure financing—and identify key stakeholders and specific requirements for burden of disease data aligned with each objective. We apply this framework to group A Streptococcus, a pathogen with an underrecognized global burden, and give specific examples pertinent to 8 clinical endpoints. This dynamic framework can be adapted for any disease with a vaccine in development and can be updated as vaccine candidates progress through clinical trials. This framework will also help with research and innovation priority setting of the Immunization Agenda 2030 (IA2030) and accelerate development of future vaccines.

Understanding the local and international stakeholders in rheumatic heart disease field in Tanzania and Uganda: A systematic stakeholder mapping

BACKGROUND

Our study aimed to systematically identify RHD stakeholders and categories of stakeholders to consider when developing a scorecard that reflects a broad stakeholder input.

METHOD

We used the Schiller et al.(2013) framework to identify RHD stakeholders and stakeholder categories in Tanzania and Uganda. The process involved identifying stakeholders by searching literature related to incidence, prevalence, morbidity, mortality, health services, or health outcomes of Group A streptococcus, acute rheumatic fever, or rheumatic heart disease in these countries. The strategy was completed for two electronic databases in 2016 and in 2020 to update the results. We also engaged known stakeholders to obtain practice-based insight. We then categorised and visually represented the identified stakeholders.

RESULTS

We identified 139 stakeholders in Uganda, with 68% being from 15 different countries across 31 locations. In comparison, local Ugandan stakeholders were dispersed in six locations across the country. In Tanzania, we identified 128 stakeholders, with 66% being locally based and dispersed in seven locations across the country and stakeholders from different countries were situated in 18 countries across 28 locations. We categorised all identified stakeholders into one or more of five categories 1) Civil Society and General Public, 2) Education Sector, 3) Research, Training and Capacity Building, 4) Healthcare service delivery, and 5) Health Policy and Administration.

CONCLUSION

The stakeholder categories identified include multiple sectors and stakeholders from multiple countries, this reflects the complexities of RHD. This also highlights the need for collaboration and partnership as a critical action for preventing and controlling RHD.

Living with Rheumatic Heart Disease at the Intersection of Biomedical and Aboriginal Worldviews

Rheumatic heart disease (RHD) significantly impacts the lives of First Nations Australians. Failure to eliminate RHD is in part attributed to healthcare strategies that fail to understand the lived experience of RHD. To rectify this, a PhD study was undertaken in the Northern Territory (NT) of Australia, combining Aboriginal ways of knowing, being and doing with interviews (24 participants from clinical and community settings) and participant observation to privilege Aboriginal voices, including the interpretations and experiences of Aboriginal co-researchers (described in the adjunct article). During analysis, Aboriginal co-researchers identified three interwoven themes: maintaining good feelings; creating clear understanding (from good information); and choosing a good djalkiri (path). These affirm a worldview that prioritises relationships, positive emotions and the wellbeing of family/community. The findings demonstrate the inter-connectedness of knowledge, choice and behaviour that become increasingly complex in stressful and traumatic health, socioeconomic, political, historical and cultural contexts. Not previously heard in the RHD domain, the findings reveal fundamental differences between Aboriginal and biomedical worldviews contributing to the failure of current approaches to communicating health messages. Mitigating this, Aboriginal co-researchers provided targeted recommendations for culturally responsive health encounters, including: communicating to create positive emotions; building trust; and providing family and community data and health messages (rather than individualistic).

Understanding factors impacting global priority of emergency care: a qualitative policy analysis

INTRODUCTION

The high burden of emergency medical conditions has not been met with adequate financial and political prioritisation especially in low and middle-income countries. We examined the factors that have shaped the priority of global emergency care and highlight potential responses by emergency care advocates.

METHODS

We conducted semistructured interviews with key experts in global emergency care practice, public health, health policy and advocacy. We then applied a policy framework based on political ethnography and content analysis to code for underlying themes.

RESULTS

We identified problem definition, coalition building, paucity of data and positioning, as the main challenges faced by emergency care advocates. Problem definition remains the key issue, with divergent ideas on what emergency care is, should be and what solutions are to be prioritised. Proponents have struggled to portray the urgency of the issue in a way that commands action from decision-makers. The lack of data further limits their effectiveness. However, there is much reason for optimism given the network's commitment to the issue, the emerging leadership and the existence of policy windows.

CONCLUSION

To improve global priority for emergency care, proponents should take advantage of the emerging governance structure and build consensus on definitions, generate data-driven solutions, find strategic framings and engage with non-traditional allies.

Rheumatic Heart Disease is Missing from the Global Health Agenda

Rheumatic heart disease (RHD) is a complication of untreated throat infection by Group A beta-hemolytic streptococcus with a high prevalence among socioeconomically disadvantaged populations. Despite its high incidence and prevalence, RHD prevention is not a priority in major global health discussions. The reasons for the apparent neglect are multifactorial, including underestimated morbidity and mortality burden, underappreciated economic burden, lack of public awareness, and lack of sustainable investment. In this review, we recommend multisectoral collaboration to tackle the burden of RHD by engaging the public, health experts, and policymakers; augmenting funding for clinical care; improving distribution channels for prophylaxis, and increasing research and innovation as critical interventions to save millions of people from preventable morbidity and mortality.

Mitral valve surgery for rheumatic heart disease: replace, repair, retrain?

PURPOSE OF REVIEW

Rheumatic heart disease (RHD) affects over 30 million people worldwide. Substantial variation exists in the surgical treatment of patients with RHD. Here, we aim to review the surgical techniques to treat RHD with a focus on rheumatic mitral valve (MV) repair. We introduce novel educational paradigms to embrace repair-oriented techniques in cardiac centers.

RECENT FINDINGS

Due to the low prevalence of RHD in high-income countries, limited expertise in MV surgery for RHD, technical complexity of MV repair for RHD and concerns about durability, most surgeons elect for MV replacement. However, in some series, MV repair is associated with improved outcomes, fewer reinterventions, and avoidance of anticoagulation-related complications. In low- and middle-income countries, the RHD burden is large and MV repair is more commonly performed due to high rates of loss-to-follow-up and barriers associated with anticoagulation, international normalized ratio monitoring, and risk of reintervention.

SUMMARY

Increased consideration for MV repair in the setting of RHD may be warranted, particularly in low- and middle-income countries. We suggest some avenues for increased exposure and training in rheumatic valve surgery through international bilateral partnership models in endemic regions, visiting surgeons from endemic regions, simulation training, and courses by professional societies.

The rise and fall of global health issues: an arenas model applied to the COVID-19 pandemic shock

Background

The global health agenda is ill-defined as an analytical construct, complicating attempts by scholars and proponents to make claims about the agenda status of issues. We draw on Kingdon’s definition of the agenda and Hilgartner and Bosk’s public arenas model to conceptualize the global health agenda as those subjects or problems to which collectivities of actors operating nationally and globally are paying serious attention at any given time. We propose an arenas model for global health agenda setting and illustrate its potential utility by assessing priority indicators in five arenas, including international aid, pharmaceutical industry, scientific research, news media and civil society. We then apply the model to illustrate how the status of established (HIV/AIDS), emergent (diabetes) and rising (Alzheimer’s disease) issues might be measured, compared and change in light of a pandemic shock (COVID-19).

Results

Coronavirus priority indicators rose precipitously in all five arenas in 2020, reflecting the kind of punctuation often caused by focusing events. The magnitude of change varied somewhat by arena, with the most pronounced shift in the global news media arena. Priority indicators for the other issues showed decreases of up to 21% and increases of up to 41% between 2019 and 2020, with increases suggesting that the agenda for global health issues expanded in some arenas in 2020— COVID-19 did not consistently displace priority for HIV/AIDS, diabetes or Alzheimer’s disease, though it might have for other issues.

Conclusions

We advance an arenas model as a novel means of addressing conceptual and measurement challenges that often undermine the validity of claims concerning the global health agenda status of problems and contributing causal factors. Our presentation of the model and illustrative analysis lays the groundwork for more systematic investigation of trends in global health agenda setting. Further specification of the model is needed to ensure accurate representation of vital national and transnational arenas and their interactions, applicability to a range of disease-specific, health systems, governance and policy issues, and sensitivity to subtler influences on global health agenda setting than pandemic shocks.

A global priority: addressing violence against children

Objective

To determine the reasons for the lack of priority given to addressing violence against children, and to identify the challenges that proponents must address to improve prioritization of this issue.

Methods

We reviewed relevant literature to identify experts to interview. We carried out a thematic analysis of the literature and interview transcripts. We iteratively developed data coding on the many characteristics of violence against children, on the framing of the issue by proponents, and on the problem of governance – that is, how proponents organize themselves for collective action.

Findings

The analysis of our data sources reveals many obstacles for global prioritization of addressing violence against children, including the forms of violence considered, inadequate data to describe prevalence and a lack of evidence of the effectiveness of proposed solutions. There exists fundamental disagreement among proponents on the recently introduced frame of violence against children, including differences in the types of violence that should be prioritized and in the proposed solutions (e.g. prevention or remediation). On governance, competition between networks focused on specific forms of violence is hampering efforts to create strong governing institutions.

Conclusion

Despite the complex challenges identified, proponents have made some progress in global prioritization of addressing violence against children. To improve this prioritization further, proponents must resolve framing tensions and strengthen governance mechanisms to promote shared goals, while ensuring that networks focused on particular forms of violence are able to maintain their distinct identities.

Generating Global Priority for Addressing Rheumatic Heart Disease: A Qualitative Policy Analysis

Background Rheumatic heart disease (RHD) poses a high burden in low-income countries, as well as among indigenous and other socioeconomically disadvantaged populations in high-income countries. Despite its severity and preventability, RHD receives insufficient global attention and resources. We conducted a qualitative policy analysis to investigate the reasons for recent growth but ongoing inadequacy in global priority for addressing RHD. Methods and Results Drawing on social science scholarship, we conducted a thematic analysis, triangulating among peer-reviewed literature, organizational documents, and 20 semistructured interviews with individuals involved in RHD research, clinical practice, and advocacy. The analysis indicates that RHD proponents face 3 linked challenges, all shaped by the nature of the issue. With respect to leadership and governance, the fact that RHD affects mostly poor populations in dispersed regions complicates efforts to coordinate activities among RHD proponents and to engage international organizations and donors. With respect to solution definition, the dearth of data on aspects of clinical management in low-income settings, difficulties preventing and addressing the disease, and the fact that RHD intersects with several disease specialties have fueled proponent disagreements about how best to address the disease. With respect to positioning, a perception that RHD is largely a problem for low-income countries and the ambiguity on its status as a noncommunicable disease have complicated efforts to convince policy makers to act. Conclusions To augment RHD global priority, proponents will need to establish more effective governance mechanisms to facilitate collective action, manage differences surrounding solutions, and identify positionings that resonate with policy makers and funders.
