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 Resilience in UNRWA Health Response to the Syrian Crisis: Lessons from Causal Loop Analysis(MIT Press, 2025) Ager, Alastair; Diaconu, Karin; Jamal, Zeina; Alameddine, Mohamad; Fouad, Fouad M.; Witter, Sophie; Blanchet, Karl1. Group model building gathers key stakeholders together to develop causal loop analysis of health system responses to experienced shocks. 2. Causal loop analysis can identify important resources and strategies supporting health system resilience. 3. Evidence of absorptive, adaptive, and transformative resilience capacities was demonstrated in UNRWA health response to the Syria crisis across Jordan, Lebanon, and Syria. 4. Analysis highlights the importance of collateral pathways and redundancy; flexible governance and leadership practices; and an organizational culture that sees challenge as an opportunity for learning and innovation. 5. Such evidence has implications for other health systems seeking to integrate provision of services to refugee populations, as well as for UNRWA itself operating in a context of political instability.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 Decision-making surrounding distress, depression and suicidal ideation: findings of a vignette study with primary health care practitioners in Lebanon [Working paper](Queen Margaret University, 2025-07) Noubani, Aya; Loffreda, Giulia; Diaconu, Karin; Muhheiddine, Dina; Horn, Rebecca; Saleh, ShadiThis working paper presents early findings from a vignette-based study exploring how primary health care (PHC) providers in Lebanon assess and respond to cases of mental ill-health, including distress, depression, and suicidal ideation. Sixty-one healthcare providers from PHC centers in Beirut and the Bekaa participated in the study using an interactive, web-based vignette tool that simulated patient cases. Each participant reviewed three vignettes varying by patient gender, nationality, and mental health severity. Providers assessed symptom severity, selected treatment options, and chose appropriate referrals. Although detailed findings are withheld to preserve the novelty of forthcoming peer-reviewed work, general trends suggest that provider decision-making varies based on professional role, patient profile, and regional context. The study underscores the potential of PHCCs to support early mental health intervention and the feasibility of vignette-based tools for research in fragile settings.Item Attitudes towards Depression among Primary Healthcare Providers in Contrasting Fragility Contexts in Lebanon: A Cross Sectional Study [Working paper](Queen Margaret University, 2025-07) Noubani, Aya; Diaconu, Karin; Muhheiddine, Dina; Alameddine, Mohammad; Saleh, ShadiBackground: Depression is a leading contributor to global disability, yet significant treatment gaps persist—particularly in fragile and low-resource settings. In Lebanon, efforts such as the WHO’s Mental Health Gap Action Programme (mhGAP) and the National Mental Health Program (NMHP) aim to improve mental health integration within primary care. This study investigates the attitudes of primary healthcare providers (HCPs) toward depression in two contrasting Lebanese contexts—urban Beirut and rural Bekaa—and examines how mhGAP training influences these attitudes. Methods: A cross-sectional survey was conducted in 2020 using the 22-item Revised Depression Attitude Questionnaire (R-DAQ) was administered to 237 HCPs across 11 Ministry of Public Health (MoPH) Primary Healthcare Centers (PHCCs) in Beirut and Bekaa. Data collection included socio-demographics, mental health training background, and clinical experience. Quantitative analysis involved descriptive statistics, t-tests, ANOVA, multiple regression, and exploratory factor analysis. Results: Most participants were female (60.3%) and based in Beirut (59.9%), with nearly half being medical doctors. While 94.4% reported frequent encounters with patients experiencing mental health issues, only 40.7% had received mental health training, and less than half of those were trained on mhGAP. Overall, HCPs held neutral-to-positive attitudes toward depression (mean R-DAQ score = 79 ± 8.08), with the strongest agreement around the need for a generalist approach. Professional confidence was moderate, and therapeutic optimism was mixed, with some respondents endorsing stigmatizing beliefs. Attitudes were significantly more positive among HCPs trained in mhGAP, working in Beirut, having postgraduate education, or regularly encountering mental health patients. Multivariable analysis confirmed that mhGAP training and practice setting were key predictors of more favorable attitudes. Exploratory factor analysis validated the original three-factor structure of the R-DAQ. Conclusion: While primary care providers in Lebanon generally support integrating mental health into routine care, gaps remain in training and confidence—especially in more fragile rural settings. Scaling up evidence-based training such as mhGAP may enhance provider preparedness and reduce stigma toward depression, supporting broader mental health reform efforts in fragile health systems.Item Qualitative system dynamics modelling to support the design and implementation of tuberculosis infection prevention and control measures in South African primary health care facilities(Oxford University Press (OUP), 2024-08-31) Diaconu, Karin; Karat, Aaron; Bozzani, Fiametta; McCreesh, Nicky; Falconer, Jennifer; Voce, Anna; Vassall, Anna; Grant, Alison D; Kielmann, KarinaTuberculosis infection prevention and control (TB IPC) measures are a cornerstone of policy, but measures are diverse and variably implemented. Limited attention has been paid to the health system environment which influences successful implementation of these measures. We used qualitative system dynamics and group-model-building methods 1) develop a qualitative causal map of the interlinked drivers of Mycobacterium tuberculosis (Mtb) transmission in South African primary health care facilities which in turn, helped us to 2) identify plausible IPC interventions to reduce risk of transmission. Two one-day participatory workshops were held in 2019 with policy- and decision-makers at national and provincial level, and patient advocates and health professionals at clinic and district level. Causal loop diagrams were generated by participants and combined by investigators. The research team reviewed diagrams to identify the drivers of nosocomial transmission of Mtb in primary health care facilities. Interventions proposed by participants were mapped onto diagrams to identify anticipated mechanisms of action and effect. Three systemic drivers were identified: 1) Mtb nosocomial transmission is driven by bottlenecks in patient flow at given times; 2) IPC implementation and clinic processes are anchored within a staff “culture of nominal compliance”; and 3) limited systems-learning at policy level inhibits effective clinic management and IPC implementation. Interventions prioritised by workshop participants included infrastructural, organisational, and behavioural strategies that target three areas: 1) improve air quality; 2) improve use of personal protective equipment; and 3) reduce the number of individuals in the clinic. In addition to core mechanisms, participants elaborated specific additional enablers that would help sustain implementation. Qualitative system dynamics modelling (SDM) methods allowed us to capture stakeholder views and potential solutions to address the problem of sub-optimal TB IPC implementation. The participatory elements of SDM facilitated problem-solving and inclusion of multiple factors frequently neglected when considering implementation.Item Enablers and barriers to implementing cholera interventions in Nigeria: a community–based system dynamics approach(Oxford University Press (OUP), 2024-07-26) Elimian, Kelly; Diaconu, Karin; Ansah, John; King, Carina; Dewa, Ozius; Yennan, Sebastian; Gandi, Benjamin; Forsberg, Birger Carl; Ihekweazu, Chikwe; Alfvén, TobiasNigeria accounts for a substantial cholera burden globally, particularly in its northeast region, where insurgency is persistent and widespread. We used participatory group model building (GMB) workshops to explore enablers and barriers to implementing known cholera interventions, including water, sanitation, and hygiene (WASH), surveillance and laboratory, case management, community engagement, oral cholera vaccine, and leadership and coordination, as well as explore leverage points for interventions and collaboration. The study engaged key cholera stakeholders in the northeastern states of Adamawa and Bauchi, as well as national stakeholders in Abuja. Adamawa and Bauchi States’ GMB participants comprised 49 community members and 43 healthcare providers, while the 23 national participants comprised government ministry, department and agency staff, and development partners. Data were analysed thematically and validated via consultation with selected participants. The study identified four overarching themes regarding the enablers and barriers to implementing cholera interventions: (1) political will, (2) health system resources and structures, (3) community trust and culture, and (4) spill-over effect of COVID-19. Specifically, inadequate political will exerts its effect directly (e.g., limited funding for prepositioning essential cholera supplies) or indirectly (e.g., overlapping policies) on implementing cholera interventions. The healthcare system structure (e.g., centralisation of cholera management in a state capital) and limited surveillance tools weaken the capacity to implement cholera interventions. Community trust emerges as integral to strengthening the healthcare system’s resilience in mitigating the impacts of cholera outbreaks. Lastly, the spill-over effects of COVID-19 helped promote interventions similar to cholera (e.g., WASH) and directly enhanced political will. In conclusion, the study offers insights into the complex barriers and enablers to implementing cholera interventions in Nigeria’s cholera-endemic settings. Strong political commitment, strengthening the healthcare system, building community trust, and an effective public health system can enhance the implementation of cholera interventions in Nigeria.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 Political Economy of Non-Communicable Disease (NCD) prevention and control in Lebanon: identifying challenges and opportunities for policy change and care provision reforms(BioMed Central, 2023-12-18) Bou-Orm, Ibrahim; Loffreda, Giulia; Diaconu, Karin; Witter, Sophie; deVos, PolIntroduction: Lebanon is a middle-income country facing substantial fragility features. Its health profile shows a high burden of NCD morbidity and mortality. This paper intends to analyse the political economy of NCD prevention and control in Lebanon. Methods: This study adopted a literature-based case study research design using a problem-driven political economy analysis framework. A total of 94 peer-reviewed articles and documents from the grey literature published before June 2019 were retrieved and analysed. Results: Lebanon’s political instability and fragile governance negatively affect its capacity to adapt a Health-in-All-Policies approach to NCD prevention and enable the blocking of NCD prevention policies by opposed stakeholders. Recent economic crises limit the fiscal capacity to address health financing issues and resulting health inequities. NCD care provision is twisted by powerful stakeholders towards a hospital-centred model with a powerful private sector. Stakeholders like the MOPH, UN agencies, and NGOs have been pushing towards changing the existing care model towards a primary care model. An incremental reform has been adopted to strengthen a network of primary care centres, support them with health technologies and improve the quality of primary care services. Nevertheless, outpatient services that are covered by other public funds remain specialist-led without much institutional regulation. Conclusion: Our study revealed a locked equilibrium in NCD prevention policymaking in Lebanon, but with an incremental progress in service delivery reforms towards a primary care model. Advocacy and close monitoring by policy entrepreneurs (such as civil society) could initiate and sustain the implementation of policy change and care model reforms.Item Influences of community engagement and health system strengthening for cholera control in cholera reporting countries(BMJ Publishing Group, 2023-12-06) Baličević, Stephanie Ayres; Elimian, Kelly Osezele; King, Carina; Diaconu, Karin; Akande, Oluwatosin Wuraola; Ihekweazu, Vivianne; Trolle, Hanna; Gaudenzi, Giulia; Forsberg, Birger; Alfven, TobiasThe 2030 Global Task Force on Cholera Control Roadmap hinges on strengthening the implementation of multistranded cholera interventions, including community engagement and health system strengthening. However, a composite picture of specific facilitators and barriers for these interventions and any overlapping factors existing between the two, is lacking. Therefore, this study aims to address this shortcoming, focusing on cholera-reporting countries, which are disproportionately affected by cholera and may be cholera endemic. A scoping methodology was chosen to allow for iterative mapping, synthesis of the available research and to pinpoint research activity for global and local cholera policy-makers and shareholders. Using the Arksey and O’Malley framework for scoping reviews, we searched PubMed, Web of Science and CINAHL. Inclusion criteria included publication in English between 1990 and 2021 and cholera as the primary document focus in an epidemic or endemic setting. Data charting was completed through narrative descriptive and thematic analysis. Forty-four documents were included, with half relating to sub-Saharan African countries, 68% (30/44) to cholera endemic settings and 21% (9/44) to insecure settings. We identified four themes of facilitators and barriers to health systems strengthening: health system cooperation and agreement with external actors; maintaining functional capacity in the face of change; good governance, focused political will and sociopolitical influences on the cholera response and insecurity and targeted destruction. Community engagement had two themes: trust building in the health system and growing social cohesion. Insecurity and the community; cooperation and agreement; and sociopolitical influences on trust building were themes of factors acting at the interface between community engagement and health system. Given the decisive role of the community–health system interface for both sustained health system strengthening and community engagement, there is a need to advocate for conflict resolution, trust building and good governance for long-term cholera prevention and control in cholera reporting countries.
