Item Navigating power in policy adoption: the political economy of noncommunicable diseases in Sierra Leone(Elsevier, 2025-10-06) Loffreda, Giulia; Senesi, Reynold; Diaconu, Karin; Idriss, Ayesha; Witter, SophieNon-communicable diseases (NCDs) represent a rising health burden globally, yet low- and middle-income countries (LMICs), particularly fragile states, face persistent barriers to NCD prevention and control policy adoption and implementation. This qualitative case study examines the factors influencing NCD policy adoption in Sierra Leone, a country that, in recent years, has focused on tackling these conditions. Drawing on 20 key informant interviews and 39 policy documents and media analysis, the study highlights the interplay of global health norms, commercial determinants, and local capacities. Findings reveal how international frameworks like WHO’s ‘best buys’ provide essential guidance but often fail to accommodate local socio-political realities. The analysis underscores how multisectoral coalitions, power dynamics, and commercial interests shape outcomes of policy adoption, while chronic underfunding and donor-driven priorities further complicate governance. Recommendations emphasize the importance of context-sensitive strategies that integrate local knowledge systems, strengthen leadership, and embed implementation research. Ultimately, fostering adaptive, accountable, and well-resourced health systems, supported by global solidarity and coordinated governance reforms, is essential to achieving sustainable NCD responses, particularly in an era marked by fractured multilateralism and weakened collective action, where strengthening local capacities and political commitment becomes even more critical.Item Understanding and addressing mental health needs and non-communicable disease in situations of fragility: RUHF research programme synopsis(NIHR, 2025) Ager, Alastair; Witter, Sophie; Diaconu, Karin; Wurie, Haja; Samai, Mohamed; Saleh, ShadiBackground: Fragile settings – marked by conflict and political, environmental, social, or economic crisis – present severe challenges to population health and the delivery of services. This is particularly the case for health conditions that require continuity of care such as non-communicable disease and mental ill-health. Objectives: To understand existing patterns of health seeking in relation to noncommunicable disease and mental health and the barriers to equitable access to quality provision. To then evaluate the feasibility, effectiveness and quality of interventions designed to address these conditions in contexts of fragility. Design and methods: Building on a foundation of focused scoping reviews, we used participatory methods – including group model building – to map pathways of access to community and health system resources in relation to non-communicable diseases and mental health. We then used a range of surveys and key informant interviews to evaluate implemented interventions. In addition, we undertook a series of global reviews of relevant topics, such as conceptualisation of fragility, the role of trust in health-seeking for noncommunicable disease care in fragile settings, analysis of policy and funding priorities of global actors regarding non-communicable diseases in low- and middle-income countries, and the political economy of NCD policy adoption and implementation at national level. Setting and participants: Field studies were focused at the district or governorate level in a range of fragile settings, including Lebanon, Sierra Leone, El Salvador and, latterly, Nigeria and Gaza. Participants included service users, (formal and informal) health providers and policy makers. Interventions: Interventions addressing NCDs included treatment protocols for hypertension and diabetes (with report cards and desk guides supporting primary care-based disease management) and a local co-created salt reduction programme (featuring community drama, school outreach and radio messaging). Mental health needs were primarily addressed in relation to the provision of community-based psychosocial support either through specific interventions (including a lay-woman-led problem solving intervention for perinatal women) or the development of assessment tools (such as a Participatory Assessment Tool for Mapping Social Connections) and contextually valid screening measures (including the Sierra Leone Psychological Distress Scale and the Sierra Leone Perinatal Psychological Distress Scale) to inform interventions. The programme also developed relevant training interventions. Main outcome measures: Measures focused on access to, and utilisation and quality of, services, including user perceptions of provision. Results: We identified a range of barriers to effective health provision in fragile settings. These reflected the cultural, political, social, economic particularities of the setting and its health system. However, trust (in specific health providers, within social and community networks, and in government) was consistently found to be a key factor in securing targeted outcomes. The skills, methods and confidence of providers was also found to be an important influence on such outcomes. Providing contextually relevant training, mentorship and tools equipped health providers in primary care settings to maintain effective, evidencebased management of diabetes and hypertension despite the ongoing challenges of their fragile context. Mobilisation of community-level resources to address non-communicable disease and mental health needs was demonstrated as relevant, feasible and potentially effective in all settings. Limitations: There was great diversity across the particular settings studied, as well as ongoing gaps in knowledge in relation to these conditions in particular. Caution should be shown in generalisation of specific findings to other situations that may not share important features. The COVID 19 pandemic disrupted data collection in both Sierra Leone and Lebanon, although the targeted power of studies was generally secured. More generally, the pandemic significantly impacted health systems operations in all settings studied, an influence that is discussed in all relevant papers. Conclusions: The research programme contributed to addressing gaps in the literature regarding effective tools and strategies to strengthen provision regarding mental health and non-communicable disease in fragile settings. Assessment of needs and barriers to accessing services is an important foundation for effective working in such contexts. This is achievable with research methods (such as group model building and remote data capture) that can accommodate the diverse challenges and uncertainty associated with these settings. Incorporating such information in service design – at the level of the community, health facility or policymaker – can secure improvement in access to, and quality of, important services. Donors and policy makers need to attend not just to the drivers of fragility but also to coherent investment in public health systems and in processes of community engagement if health needs are to be meaningfully addressed. Future work: The conceptualisation of fragility (and resilience) developed through this programme is informing the design of community, health system and wider cross-sectoral interventions in fragile contexts through the ReBuild for Resilience programme in settings including Sierra Leone, Lebanon, Myanmar and Nepal. Further work across diverse contexts of fragility is required to both identify common features and principles required for health response in these settings and refine strategies and tools that can readily be adapted to the unique characteristics of any particular context.Item Barriers and Opportunities for WHO ‘Best Buys’ Non-Communicable Disease Policy Adoption and Implementation From a Political Economy Perspective: A Complexity Systematic Review(Maad Rayan Publishing Company, 2023-12-31) Loffreda, Giulia; Arakelyan, Stella; Bou-Orm, Ibrahim; Holmer, Hampus; Allen, Luke N.; Witter, Sophie; Ager, Alastair; Diaconu, KarinBackground: Improving the adoption and implementation of policies to curb noncommunicable diseases (NCDs) is a major challenge for better global health. The adoption and implementation of such policies remain deficient in various contexts, with limited insights into the facilitating and inhibiting factors. These policies have traditionally been treated as technical solutions, neglecting the critical influence of political economy dynamics. Moreover, the complex nature of these interventions is often not adequately incorporated into evidence for policymakers. This study aims to systematically review and evaluate the factors affecting NCD policy adoption and implementation. Methods: We conducted a complex systematic review of articles discussing the adoption and implementation of WHO's ‘best buys' NCD policies. We identified political economy factors and constructed a causal loop diagram (CLD) program theory to elucidate the interplay between factors influencing NCD policy adoption and implementation. A total of 157 papers met the inclusion criteria. Results: Our CLD highlights a central feedback loop encompassing three vital variables: 1) the ability to define, (re)shape and pass appropriate policy into law; 2) the ability to implement the policy (linked to the enforceability of the policy and to addressing NCD local burden); 3) ability to monitor progress, evaluate and correct the course. Insufficient context-specific data impedes the formulation and enactment of suitable policies, particularly in areas facing multiple disease burdens. Multisectoral collaboration plays a pivotal role in both policy adoption and implementation. Effective monitoring and accountability systems significantly impact policy implementation. The commercial determinants of health (CDoH) serve as a major barrier to defining, adopting, and implementing tobacco, alcohol, and diet-related policies. Conclusion: To advance global efforts, we recommend focusing on the development of robust accountability, monitoring, and evaluation systems, ensuring transparency in private sector engagement, supporting context-specific data collection, and effectively managing the CDoH. A system thinking approach can enhance the implementation of complex public health interventions.Item Complexity and evidence in health sector decision-making: lessons from tuberculosis infection prevention in South Africa(Oxford University Press (OUP), 2022-07-29) Perera, Shehani; Parkhurst, Justin; Diaconu, Karin; Bozzani, Fiammetta; Vassall, Anna; Grant, Alison; Kielmann, KarinaAbstract To better understand and plan health systems featuring multiple levels and complex causal elements, there have been increasing attempts to incorporate tools arising from complexity science to inform decisions. The utilization of new planning approaches can have important implications for the types of evidence that inform health policymaking and the mechanisms through which they do so. This paper presents an empirical analysis of the application of one such tool—system dynamics modelling (SDM)—within a tuberculosis control programme in South Africa in order to explore how SDM was utilized, and to reflect on the implications for evidence-informed health policymaking. We observed group model building workshops that served to develop the SDM process and undertook 19 qualitative interviews with policymakers and practitioners who partook in these workshops. We analysed the relationship between the SDM process and the use of evidence for policymaking through four conceptual perspectives: (1) a rationalist knowledge-translation view that considers how previously-generated research can be taken up into policy; (2) a programmatic approach that considers existing goals and tasks of decision-makers, and how evidence might address them; (3) a social constructivist lens exploring how the process of using an evidentiary planning tool like SDM can shape the understanding of problems and their solutions; and (4) a normative perspective that recognizes that stakeholders may have different priorities, and thus considers which groups are included and represented in the process. Each perspective can provide useful insights into the SDM process and the political nature of evidence use. In particular, SDM can provide technical information to solve problems, potentially leave out other concerns and influence how problems are conceptualized by formalizing the boundaries of the policy problem and delineating particular solution sets. Undertaking the process further involves choices on stakeholder inclusion affecting whose interests may be served as evidence to inform decisions.Item Outpatient use patterns and experiences among diabetic and hypertensive patients in fragile settings: A cross-sectional study from Lebanon(BMJ, 2022-05-23) Saleh, Shadi; Muhieddine, Dina; Hamadeh, Randa S.; Dimassi, Hani; Diaconu, Karin; Noubani, Aya; Arakelyan, Stella; Ager, Alastair; Alameddine, MohamadObjectives: Assess and describe the health service use and delivery patterns for non-communicable disease (NCD) services in two contrasting fragility contexts and by other principal equity-related characteristics including gender, nationality and health coverage. Setting: Primary healthcare centres located in the urbanised area of Greater Beirut and the rural area of the Beqaa Valley. Design: This is a cross-sectional study using a structured survey tool between January and September 2020. Participants: 1700 Lebanese and Syrian refugee patients seeking primary care for hypertension and diabetes. Primary and secondary outcomes: The main outcome is the comprehensiveness of service delivery comparing differences in use and service delivery patterns by fragility setting, gender, nationality and health coverage. Results: Compliance with routine NCD care management (eg, counselling, immunisations, diagnostic testing and referral rates) was significantly better in Beirut compared with Beqaa. Women were significantly less likely to be offered lifestyle counselling advice and referral to cardiologists (58.4% vs 68.3% in Beqaa and 58.1% vs 62% in Beirut) and ophthalmologists, compared with men. Across both settings, there was a significant trend for Lebanese patients to receive more services and more advice related to nutrition and diabetes management (89.8% vs 85.2% and 62.4% vs 55.5%, respectively). Similarly, referral rates were higher among Lebanese refugees compared with Syrian refugees. Immunisation and diagnostic testing were significantly higher in Beirut among those who have health coverage compared with Beqaa. Conclusions: The study discovered significant differences in outpatient service use by setting, nationality and gender to differentials. A rigorous and comprehensive appraisal of NCD programmes and services is imperative for providing policy makers with evidence-based recommendations to guide the design, implementation and evaluation of targeted programmes and services necessary to ensure equity in health services delivery to diabetic and hypertensive patients. Such programmes are an ethical imperative considering the protracted crises and compounded fragility.Item Using system dynamics modelling to estimate the costs of relaxing health system constraints: A case study of tuberculosis prevention and control interventions in South Africa(Oxford University Press, 2022-01-13) Bozzani, Fiammetta M.; Diaconu, Karin; Gomez, Gabriela B.; Karat, Aaron S.; Kielmann, Karina; Grant, Alison D.; Vassall, AnnaHealth system constraints are increasingly recognised as an important addition to model-based analyses of disease control interventions, as they affect achievable impact and scale. Enabling activities implemented alongside interventions to relax constraints and reach the intended coverage may incur additional costs, which should be considered in priority setting decisions. We explore the use of group model building, a participatory system dynamics modelling technique, for eliciting information from key stakeholders on the constraints that apply to tuberculosis infection prevention and control processes within primary healthcare clinics in South Africa. This information was used to design feasible interventions, including the necessary enablers to relax existing constraints. Intervention and enabler costs were then calculated at two clinics in KwaZulu-Natal using input prices and quantities from the published literature and local suppliers. Among the proposed interventions, the most inexpensive were retrofitting buildings to improve ventilation (US$ 1,644 per year), followed by maximising the use of community sites for medication collection among stable patients on antiretroviral therapy (US$ 3,753) and introducing appointments systems to reduce crowding (US$ 9,302). Enablers identified included enhanced staff training, supervision and patient engagement activities to support behaviour change and local ownership. Several of the enablers identified by the stakeholders, such as obtaining building permissions or improving information flows between levels of the health systems, were not amenable to costing. Despite this limitation, an approach to costing rooted in system dynamics modelling can be successfully applied in economic evaluations to more accurately estimate the ‘real world’ opportunity cost of intervention options. Further empirical research applying this approach to different intervention types (e.g. new preventive technologies or diagnostics) may identify interventions that are not cost-effective in specific contexts based on the size of the required investment in enablers.Item How do participatory methods shape policy? Applying a realist approach to the formulation of a new tuberculosis policy in Georgia(2021-06-29) Marchal, Bruno; Abejirinde, Ibukun-Oluwa Omolade; Sulaberidze, Lela; Chikovani, Ivdity; Uchaneishvili, Maia; Shengelia, Natia; Diaconu, Karin; Vassall, Anna; Zoidze, Akaki; Giralt, Ariadna Nebot; Witter, SophieThis paper presents the iterative process of participatory multistakeholder engagement that informed the development of a new national tuberculosis (TB) policy in Georgia, and the lessons learnt. Guided by realist evaluation methods, a multistakeholder dialogue was organised to elicit stakeholders' assumptions on challenges and possible solutions for better TB control. Two participatory workshops were conducted with key actors, interspersed by reflection meetings within the research team and discussions with policymakers. Using concept mapping and causal mapping techniques, and drawing causal loop diagrams, we visualised how actors understood TB service provision challenges and the potential means by which a results-based financing (RBF) policy could address these. The study was conducted in Tbilisi, Georgia. A total of 64 key actors from the Ministry of Labour, Health and Social Affairs, staff of the Global Fund to Fight AIDS, TB and Malaria Georgia Project, the National Centre for Disease Control and Public Health, the National TB programme, TB service providers and members of the research team were involved in the workshops. Findings showed that beyond provider incentives, additional policy components were necessary. These included broadening the incentive package to include institutional and organisational incentives, retraining service providers, clear redistribution of roles to support an integrated care model, and refinement of monitoring tools. Health system elements, such as effective referral systems and health information systems were highlighted as necessary for service improvement. Developing policies that address complex issues requires methods that facilitate linkages between multiple stakeholders and between theory and practice. Such participatory approaches can be informed by realist evaluation principles and visually facilitated by causal loop diagrams. This approach allowed us leverage stakeholders' knowledge and expertise on TB service delivery and RBF to codesign a new policy. [Abstract copyright: © Author(s) (or their employer(s)) 2021.

Migration towards neighbouring countries or more distant high-income settings in Europe is creating new challenges for national health systems. This chapter explores health systems resilience, i.e. the capacity of health systems to adapt and transform themselves in response to challenges. We offer reflections and a new conceptual framework on resilience based on systems thinking and complexity theories. The chapter also offers examples of migration-related challenges and resilience responses in health systems and policies in order to illustrate the utility and relevance of the developed conceptual framework for European and neighbouring health systems faced by population flows and conflict. Finally, we make recommendations for a new research agenda.
