Latent class analysis of barriers to HIV testing services and associations with sexual behaviour and HIV status among adolescents and young adults in Nigeria.

INTRODUCTION: Adolescents and young adults (AYA) face multiple barriers to accessing healthcare services, which can interact, creating complex needs that often impact health behaviours, leading to increased vulnerability to HIV. We aimed to identify distinct AYA subgroups based on patterns of barriers to HIV testing services and assess the association between these barrier patterns and sexual behaviour, socio-demographics, and HIV status. METHODS: Data were from Nigeria's AIDS Indicator and Impact Survey (NAIIS, 2018) and included 18,612 sexually active AYA aged 15-24 years who had never been tested for HIV and reported barriers to accessing HIV testing services. A Latent class analysis (LCA) model was built from 12 self-reported barrier types to identify distinct subgroups of AYA based on barrier patterns. Latent class regressions (LCR) were conducted to compare the socio-demographics, sexual behaviour, and HIV status across identified AYA subgroups. Sex behaviour characteristics include intergenerational sex, transactional sex, multiple sex partners, condom use, and knowledge of partner's HIV status. RESULTS: Our LCA model identified four distinct AYA subgroups termed 'low-risk perception' (n = 7,361; 39.5%), 'consent and proximity' (n = 5,163; 27.74%), 'testing site' (n = 4,996; 26.84%), and 'cost and logistics' (n = 1,092; 5.87%). Compared to adolescents and young adults (AYA) in the low-risk perception class, those in the consent and proximity class were more likely to report engaging in intergenerational sex (aOR 1.17, 95% CI 1.02-1.35), transactional sex (aOR 1.50, 95% CI 1.23-1.84), and have multiple sex partners (aOR 1.75, 95% CI 1.39-2.20), while being less likely to report condom use (aOR 0.79, 95% CI 0.63-0.99). AYA in the testing site class were more likely to report intergenerational sex (aOR 1.21, 95% CI 1.04-1.39) and transactional sex (aOR 1.53, 95% CI 1.26-1.85). AYA in the cost and logistics class were more likely to engage in transactional sex (aOR 2.12, 95% CI 1.58-2.84) and less likely to report condom use (aOR 0.58, 95% CI 0.34-0.98). There was no significant relationship between barrier subgroup membership and HIV status. However, being female, aged 15-24 years, married or cohabiting, residing in the Southsouth zone, and of Christian religion increased the likelihood of being HIV infected. CONCLUSIONS: Patterns of barriers to HIV testing are linked with differences in sexual behaviour and sociodemographic profiles among AYA, with the latter driving differences in HIV status. Findings can improve combination healthcare packages aimed at simultaneously addressing multiple barriers and determinants of vulnerability to HIV among AYA.

Youth-centred participatory action approach towards co-created implementation of socially and physically activating environmental interventions in Africa and Europe: the YoPA project study protocol.

INTRODUCTION: The majority of adolescents do not meet guidelines for healthy behaviours, posing major risks for developing multiple non-communicable diseases. Unhealthy lifestyles seem more prevalent in urban than rural areas, with the neighbourhood environment as a mediating pathway. How to develop and implement sustainable and effective interventions focused on adolescent health and well-being in urban vulnerable life situations is a key challenge. This paper describes the protocol of a Youth-centred Participatory Action (YoPA) project aiming to tailor, implement, and evaluate social and physical environmental interventions. METHODS AND ANALYSIS: In diverse urban environments in Denmark, the Netherlands, Nigeria and South Africa, we will engage a dynamic group of 15-20 adolescents (12-19 years) growing up in vulnerable life situations and other key stakeholders (eg, policy makers, urban planners, community leaders) in local co-creation communities. Together with academic researchers and local stakeholders, adolescents will take a leading role in mapping the local system; tailoring; implementing and evaluating interventions during participatory meetings over the course of 3 years. YoPA applies a participatory mixed methods design guided by a novel Systems, User perspectives, Participatory co-creation process, Effects, Reach, Adoption, Implementation and Maintenance framework assessing: (i) the local systems, (ii) user perspectives, (iii) the participatory co-creation process, (iv) effects, (v) reach, (vi) adoption, (vii) implementation and (viii) maintenance of interventions. Through a realist evaluation, YoPA will explore why and how specific outcomes were reached (or not) in each setting (n=800-1000 adolescents in total). ETHICS AND DISSEMINATION: This study received approval from the ethics committees in Denmark, the Netherlands, Nigeria and South Africa and will be disseminated via various collaborative dissemination activities targeting multiple audiences. We will obtain informed consent from all participants. We envision that our YoPA co-creation approach will serve as a guide for participation of adolescents in vulnerable life situations in implementation of health promotion and urban planning in Europe, Africa and globally. TRIAL REGISTRATION NUMBER: NCT06181162.

Mental health of sexual assault victims and predictors of their use of support from in-house psychologists at Belgian sexual assault care centres.

BACKGROUND: Sexual assault (SA) can induce a negative impact on victims' mental health. Specialised SA services generally offer medical care and a forensic examination to SA victims. However, there is a large variation in how these services provide mental health support. OBJECTIVE: This study aims to assess mental health problems of SA victims attending the Belgian Sexual Assault Care Centres (SACCs) and identify predictors for victims' use of support from in-house psychologists. METHOD: Health records of victims ≥ 16 years who presented within one week post-SA to one of the three Belgian SACCs between 25 October 2017 and 31 October 2019 were reviewed. An AIC-based stepwise backward binary logistic regression was used to analyse the association between victim, assault, service use and mental health characteristics and follow-up by a SACC-psychologist. RESULTS: Of the 555 victims, more than half had a history of mental health problems. Of those assessed, over 70% showed symptoms of posttraumatic stress disorder (PTSD), depression and/or anxiety disorder. One in two victims consulted a SACC-psychologist. Victims with a mental health history (OR 1.46, p = .04), victims accompanied by a support person during acute care (OR 1.51, p = .04), and victims who were assaulted by an acquaintance in comparison to those assaulted by a stranger (OR 1.60, p = .039) were more likely to attend their appointment with the SACC-psychologist. CONCLUSION: The study reaffirms the high mental health burden among victims attending specialised SA services, stressing the need to provide effective mental health interventions at these services and improve their longer-term use by victims. Prescheduling of appointments with an in-house psychologist in combination with phone reminders may improve the uptake of such services. Health care providers must be vigilant about potential barriers faced by victims without a mental health history or social support in attending appointments with mental health professionals.

The mental health burden is high among victims attending Belgian Sexual Assault Care Centres.Half of the victims use the support of an in-house psychologist. Victims with a history of mental health problems, those accompanied by a support person during acute care, and those assaulted by an acquaintance in comparison to those assaulted by a stranger, are more likely to use this support.Effective mental health support should be recognised as an integral and essential part of care for SA victims. Uptake and longer-term engagement with this mental health support should be improved for those victims diagnosed with PTSD.

Using the multiple streams model to elicit an initial programme theory: from policy dialogues to a roadmap for scaling up integrated care.

INTRODUCTION: The 'SCale-Up diaBetes and hYpertension care' Project aims to support the scale-up of integrated care for diabetes and hypertension in Cambodia, Slovenia and Belgium through the co-creation, implementation and evaluation of contextualised roadmaps. These roadmaps offer avenues for action and are built on evidence as well as stakeholder engagement in policy dialogues. Roadmaps and policy dialogues are very much intertwined and considered to be key elements for successful stakeholder-supported scale-up in integrated chronic care. Yet, little is known about how, why and under which conditions policy dialogue leads to successful roadmap implementation and scale-up of integrated care. Therefore, this study aims to use a realist approach to elicit an initial programme theory (IPT), using political science theories on the policy process. METHODS: To develop the IPT, information from different sources was collected. First, an exploratory literature review on policy dialogue and scale-up definitions and success factors was performed, identifying theoretical frameworks, empirical (case) studies and realist studies (information gleaning). Second, research workshops on applying theory to the roadmap for scale-up (theory gleaning) were conducted with a multidisciplinary expert team. We used the intervention-context-actors-mechanism-outcome configuration to synthesise information from the sources into a configurational map. RESULTS: The information and theory gleaning resulted into an IPT, hypothesising how policy dialogues can contribute to roadmap success in different policy stages. The IPT draws on political science theory of the multiple streams model adapted by Howlett et al to include five streams (problem, solution, politics, process and programme) that can emerge, converge and diverge across all five policy stages. CONCLUSION: This paper aims to extend the knowledge base on the use of policy dialogues to build a roadmap for scale-up. The IPT describes how (dynamics) and why (theories) co-created roadmaps are expected to work in different policy stages.

Understanding why and how youth-friendly health services improve viral load suppression among adolescents and young people living with HIV in Nigeria: realist evaluation with qualitative comparative analysis.

INTRODUCTION: Youth-friendly health service (YFHS) approaches are essential to better outcomes for young people. We evaluated attainment of viral load suppression among young people living with HIV (YPLHIV) enrolled in an HIV treatment programme implementing YFHS models in Nigeria. METHODS: A realist evaluation using qualitative and quantitative programme data from 10 implementing health facilities. We used qualitative information to explore how and why viral load suppression was attained across different settings and quantitative data to describe patterns and associations between youth-friendly structures and processes of care, care retention and viral load suppression. To consolidate the theories, we used qualitative comparative analysis to identify the necessary and sufficient conditions for attaining viral load suppression, using 30 YPLHIV as cases. RESULTS: Between baseline (2018) and study-end (May 2022), viral load suppression coverage increased in 8 of the 10 study facilities. The number of facilities with viral load suppression coverage ≥90% rose from two to seven, while one facility remained unchanged, and another had a decline in coverage. Among the 30 selected YPLHIV cases, 18 had viral load suppression during the first test and 24 at the second test. However, viral load suppression attainment varied in different contexts. We identified the different YFHS interventions and key mechanisms that influenced viral load suppression in different contexts. CONCLUSION: YFHS interventions can improve young people's engagement with HIV services, but their effectiveness depends on specific mechanisms and contextual factors influencing their response to interventions. By exploring how and why viral load suppression was attained in different contexts, the findings will improve the design and implementation of strategies to improve outcomes in young people, which will be relevant for achievement of global goals to eliminate HIV by 2030.

Factors Related to Police Reporting in Sexual Assault Care Centers: Are We Underestimating the Role of Support Persons?

Few victims of sexual assault (SA) report to the police. Research on the role of support persons in victims' reporting is sparse. We address this gap by examining the association of victim, assailant, victimization incident, and support characteristics with reporting rates among victims attending sexual assault care centers (SACCs). Logistic regression results show that type of SA, delay between SA and presentation at SACC, and presence of an informal support person at SACC and SACC site are significantly associated with police reporting. These findings reveal the importance of targeting victims' support persons to alter reporting behavior among SA victims.

Initial programme theory for community-based ART delivery for key populations in Benue State, Nigeria: a realist evaluation study.

BACKGROUND: The community-based antiretroviral therapy delivery (CBART) model was implemented in Benue State in Nigeria to increase access of key populations living with HIV (KPLHIV) to antiretroviral treatment. Key populations (KP) are female sex workers, men who have sex with men, persons who inject drugs, and transgender people. Evidence shows that the CBART model for KP (KP-CBART) can improve HIV outcomes along the cascade of HIV care and treatment in sub-Saharan Africa. However, how KP-CBART works, for whom, why, and under what circumstances it generates specific outcomes are not yet clear. Therefore, the aim of this study is to identify the initial programme theory (IPT) of the KP-CBART in Benue State using a realist approach. METHOD: The study design is exploratory and qualitative, exploring the implementation of KP-CBART. We reviewed the intervention logic framework & guidelines for the KP-CBART in Nigeria, conducted a desk review of KP-CBART in Sub-Saharan Africa (SSA) and interviewed programme managers in the Benue HIV programme between November 2021 and April 2022. Findings were synthesized using the Context-Mechanism-Outcome (CMO) heuristic tool to explain the relationship between the different types of CBART models, contextual factors, actors, mechanisms and outcomes. Using a generative causality logic (retroduction and abduction), we developed, following a realist approach, CMO configurations (CMOc), summarized as an empirically testable IPT. RESULT: We developed 7 CMOc and an IPT of the KP-CBART. Where KPLHIV receive ART in a safe place while living in a setting of punitive laws, harassment, stigma and discrimination, KP will adhere to treatment and be retained in care because they feel safe and trust the healthcare providers. Where KPLHIV are involved in the design, planning and implementation of HIV services; medication adherence and retention in care will improve because KP clients perceive HIV services to be KP-friendly and participate in KP-CBART. CONCLUSION: Implementation of CBART model where KPLHIV feel safe, trust healthcare providers, and participate in HIV service delivery can improve medication adherence and retention in care. This programme hypothesis will be tested and refined in the next phase of the realist evaluation of KP-CBART.

Decolonisation initiatives at the Institute of Tropical Medicine, Antwerp, Belgium: ready for change?

In a global context, the pernicious effects of colonialism and coloniality are increasingly being recognised in many sectors. As a result, calls to reverse colonial aphasia and amnesia, and decolonise, are getting stronger. This raises a number of questions, particularly for entities that acted as agents of (previous) colonising countries and worked to further the progress of the colonial project: What does decolonisation mean for such historically colonial entities? How can they confront their (forgotten) arsonist past while addressing their current role in maintaining coloniality, at home and abroad? Given the embeddedness of many such entities in current global (power) structures of coloniality, do these entities really want change, and if so, how can such entities redefine their future to ensure that they are and remain 'decolonised'? We attempt to answer these questions, by reflecting on our efforts to think through and start the process of decolonisation at the Institute of Tropical Medicine (ITM) in Antwerp, Belgium. The overarching aim is to contribute to closing the gap in the literature when it comes to documenting practical efforts at decolonisation, particularly in contexts similar to ITM and to share our experience and engage with others who are undertaking or planning to undertake similar initiatives.

"It's like asking for a necktie when you don't have underwear": Discourses on patient rights in southern Karnataka, India.

BACKGROUND: Ensuring patient rights is an extension of applying human rights principles to health care. A critical examination of how the notion of patient rights is perceived and enacted by various actors through critical discourse analysis (CDA) can help understand the impediments to its realization in practice. METHODS: We studied the discourses and discursive practices on patient rights in subnational policies and in ten health facilities in southern Karnataka, India. We conducted interviews (78), focus group discussions (3) with care-seeking individuals, care-providers, health care administrators and public health officials. We also conducted participant observation in selected health facilities and examined subnational policy documents of Karnataka pertaining to patient rights. We analyzed the qualitative data for major and minor themes. RESULTS: Patient rights discourses were not based upon human rights notions. In the context of neoliberalism, they were predominantly embedded within the logic of quality of care, economic, and consumerist perspectives. Relatively powerful actors such as care-providers and health facility administrators used a panoply of discursive strategies such as emphasizing alternate discourses and controlling discursive resources to suppress the promotion of patient rights among care-seeking individuals in health facilities. As a result, the capacity of care-seeking individuals to know and claim patient rights was restricted. With neoliberal health policies promoting austerity measures on public health care system and weak implementation of health care regulations, patient rights discourses remained subdued in health facilities in Karnataka, India. CONCLUSIONS: The empirical findings on the local expression of patient rights in the discourses allowed for theoretical insights on the translation of conceptual understandings of patient rights to practice in the everyday lives of health system actors and care-seeking individuals. The CDA approach was helpful to identify the problematic aspects of discourses and discursive practices on patient rights where health facility administrators and care-providers wielded power to oppress care-seeking individuals. From the practical point of view, the study demonstrated the limitations of care-seeking individuals in the discursive realms to assert their agency as practitioners of (patient) rights in health facilities.

Multilevel Governance and Control of the COVID-19 Pandemic in the Democratic Republic of Congo: Learning from the Four First Waves.

The COVID-19 pandemic continues to impose a heavy burden on people around the world. The Democratic Republic of the Congo (DRC) has also been affected. The objective of this study was to explore national policy responses to the COVID-19 pandemic in the DRC and drivers of the response, and to generate lessons for strengthening health systems' resilience and public health capacity to respond to health security threats. This was a case study with data collected through a literature review and in-depth interviews with key informants. Data analysis was carried out manually using thematic content analysis translated into a logical and descriptive summary of the results. The management of the response to the COVID-19 pandemic reflected multilevel governance. It implied a centralized command and a decentralized implementation. The centralized command at the national level mostly involved state actors organized into ad hoc structures. The decentralized implementation involved state actors at the provincial and peripheral level including two other ad hoc structures. Non-state actors were involved at both levels. These ad hoc structures had problems coordinating the transmission of information to the public as they were operating outside the normative framework of the health system. Conclusions: Lessons that can be learned from this study include the strategic organisation of the response inspired by previous experiences with epidemics; the need to decentralize decision-making power to anticipate or respond quickly and adequately to a threat such as the COVID-19 pandemic; and measures decided, taken, or adapted according to the epidemiological evolution (cases and deaths) of the epidemic and its effects on the socio-economic situation of the population. Other countries can benefit from the DRC experience by adapting it to their own context.

Why are they "unreached"? Macro and Meso determinants of health care access in hard to reach areas of Odisha, India.

BACKGROUND: Reaching hard to reach populations is key to reduce health inequities. Despite targeted interventions, status of crucial public health indicators like neonatal and maternal mortality is still far from optimal. Complex interplay of social determinants can influence both communities and health care workers to effectively access each other. We argue that culturally sensitive and contextually relevant healthcare provision has potential to increase health care utilization by the vulnerable communities living in remote areas. METHODS: The study is an exploratory case study using rapid ethnographic techniques to understand the interplay of social determinants in hard to reach areas of Odisha state, India. We used in-depth interviews, focus group discussion, participatory action research and key informant interviews as tools for data collection. The analysis of data has been guided by thematic analysis approach. RESULTS: We found that there are further layers within the designated hard to reach areas and those can be designated as-i) extremely remote ii) remote and iii) reachable areas. Degree of geographic difficulties and cultural dynamics are deciding the 'perceived' isolation and interaction with health care providers in hard to reach areas. This ultimately leads to impacting the utilization of the facilities. At extremely remote areas, felt health needs are mainly fulfilled by traditional healers and ethno-medical practices. In reachable areas, people are more prone to seek care from the public health facilities because of easy accessibility and outreach. Being in middle people in remote areas, diversify health care seeking depending upon social (e.g. patient's gender) economic (e.g. avoid catastrophic expenditure) and health system (timely availability of health human resources, language barriers) factors. CONCLUSION: Our research highlights the need to value and appreciate different worldviews, beliefs and practices, and their understanding of and engagement with the pluralistic health care system around them. Other than pursuing the 'mainstreaming' of a standardized health system model across hard to reach areas, strategies need to be adaptive as per local factors. To handle that existing policies need revision with a focus on culturally sensitive and contextual care provision.

Outcomes of a community-based antiretroviral therapy programme for key populations living with HIV in Benue State, Nigeria: protocol for a realist evaluation.

INTRODUCTION: Key populations (KP) living with HIV are underserved and often face social and health system barriers to HIV care. To optimise access to quality HIV services among KP, the WHO recommended community-based approaches to HIV service delivery for KP. However, to inform the successful rollout and scale-up of community-based antiretroviral therapy service delivery models for KP (KP-CBART), there is a need to study the programme implementation. This study aims to evaluate the outcomes of KP-CBART in Benue State Nigeria using a realist impact evaluation approach. Our evaluation question is: what are the mechanisms and context conditions that drive successful community-based implementation and how do these lead to better retention in care, treatment adherence and viral suppression among which categories of KP? METHODS AND ANALYSIS: This study will be conducted in three phases, relying on a mixed-method design and following the realist evaluation cycle. The first phase is the development of the initial programme theory grounded in a scoping review, programme and policy document review and in-depth interviews with key stakeholders. In phase 2, findings from case studies of KP-CBART programme implementation in one Nigerian state are used to test the initial programme theory and to refine it. The quantitative part is a retrospective cohort study. All HIV-positive KP clients enrolled into the KP-CBART between 2016 and 2020 will be included in the study. While maximum variation and data saturation will inform sample size for the qualitative part, an estimated 90 purposively selected study participants will be interviewed. In phase 3, findings will be synthesised into a middle-range theory through cross-case analysis. The heuristic intervention, context, agents, mechanisms and outcomes (ICAMO) tool will be used to refine the initial programme theory. ETHICS AND DISSEMINATION: The study protocol was approved by the Institutional Review Boards of APIN Public Health Initiatives (IRB022-FR), Institute of Tropical Medicine Antwerp (1503/21), and the Benue State Ministry of Health and Human Services (MOH/STA/204/VOL1/154). Written informed consent will be obtained from all study participants. Study results will be disseminated through stakeholders meeting, peer-reviewed journals and conferences.

A Realist-Informed Review of Digital Empowerment Strategies for Adolescents to Improve Their Sexual and Reproductive Health and Well-being.

The use of digital technologies for health has been rapidly gaining ground in the last decade, including as a strategy to empower adolescents living in urban resource-constrained settings. Nevertheless, unclarity and incoherence remain regarding which programme strategies generate which outcomes, as well as regarding the importance of context. We set out to answer the question "How do digital empowerment strategies work to improve adolescent health and well-being?". We conducted a realist-informed review, the first on this subject matter to our knowledge. The realist methodology is geared towards the understanding of socially complex interventions, such as digital empowerment. We synthesized the data into a programme theory uncovering social mechanisms and context conditions underlying specific programme strategies. We found that digital technologies enlarge the space for adolescents to access information to health services on their own terms and provide anonymity, which leads to a sense of safety if access is not curbed by gatekeepers. If adolescents have access to information adapted to their needs, they will be able to make informed decisions, and this will contribute to improved health outcomes because their better understanding enlarges their sense of individual agency. We identified two main gaps in the literature on digital interventions for adolescents. Both are related to an under-theoretisation of the concepts the programmes rely on in implementation: (1) the urban environment the programme has to operate in and its meaning for the adolescents; (2) the socio-developmental stage of the adolescents the programmes work in.

Not for us, without us: examining horizontal coordination between the Ministry of Health and other sectors to advance health goals in Uganda.

The Ministry or Department of Health (M/DoH) is the mandated government agency for health in all countries. However, achieving good health and wellbeing requires the health sector to coordinate with other sectors such as the environment, agriculture and education. Little is known about the coordination relationship between MoH and other sectors to advance health and development goals in low- and middle-income countries (LMICs). Our study examined the coordination relationship between MoH and other government ministries, departments and agencies (MDAs) at the national level in Uganda. This was an embedded case study nested in a study on intragovernmental coordination at the central government in Uganda. A qualitative approach used document review and key informant interviews with government officials and non-state actors. Data were analysed thematically using a multitheoretical framework. The coordination relationship was characterized by interdependencies generally framed lopsidedly in terms of health sector goals and not vice versa. Actor opportunism and asymmetrical interests interacted with structural-institutional factors contributing to variable influence on internal and external coordination within and beyond MOH. Supportive mechanisms include (a) diverse health sector legal-institutional frameworks, (b) their alignment to broader government efforts and (c) the MOH's agency to leverage government-wide efforts. Constraints arose from (a) gaps in the legal-institutional framework, (b) demands on resources due to the 'broad' MOH mandate and (c) the norms of the MOH's professional bureaucracy and the predominance of medical professionals. This study underlines critical actions needed to improve coordination between the health and non-health sectors. Introspection within the MOH is vital to inform efforts to modify MOH's internal functioning and positioning within the broader government to strategically advance MOH's (development) aspirations. The nature of MoH's role in multisectoral efforts should be contingent. Consideration of mutual sectoral interdependencies and interactions with and within broader government systems is critical.

Methodological reflections on health system-oriented assessment of maternity care in 16 hospitals in sub-Saharan Africa: an embedded case study.

Health facility assessments (HFAs) assessing facilities' readiness to provide services are well-established. However, HFA questionnaires are typically quantitative and lack depth to understand systems in which health facilities operate-crucial to designing context-oriented interventions. We report lessons from a multiple embedded case study exploring the experiences of HFA data collectors in implementing a novel HFA tool developed using systems thinking approach. We assessed 16 hospitals in four countries (Benin, Malawi, Tanzania and Uganda) as part of a quality improvement implementation research. Our tool was organized in 17 sections and included dimensions of hospital governance, leadership and financing; maternity care standards and procedures; ongoing quality improvement practices; interactions with communities and mapping of the areas related to maternal care. Data for this study were collected using in-depth interviews with senior experts who conducted the HFA in the countries 1-3 months after completion of the HFAs. Data were analysed using the inductive thematic analysis approach. Our HFA faced challenges in logistics (accessing key hospital-based respondents, high turnover of managerial staff and difficulty accessing information considered sensitive in the context) and methodology (response bias, lack of data quality and data entry into an electronic platform). Data elements of governance, leadership and financing were the most affected. Opportunities and strategies adopted aimed at enhancing data collection (building on prior partnerships and understanding local and institutional bureaucracies) and enhancing data richness (identifying respondents with institutional memory, learning from experience and conducting observations at various times). Moreover, HFA data collectors conducted abstraction of records and interviews in a flexible and adaptive way to enhance data quality. Lessons and new skills learned from our HFA could be used as inputs to respond to the growing need of integrating the systems thinking approach in HFA to improve the contextual understanding of operations and structure.

What are the tools available for the job? Coordination instruments at Uganda's national government level and their implications for multisectoral action for health.

Managing sectoral interdependences requires functional tools that facilitate coordinated multisectoral efforts. The pursuit of multisectoral action for health is intrinsically linked to broader efforts in many governments to achieve greater internal coordination. This research explores the nature of coordination instruments for multisectoral action at the national level in Uganda and the complexities of how these tools play out in implementation. Data was collected through 26 purposive in-depth interviews with national-level stakeholders, including government officials and non-state actors, and a review of selected government strategic documents. A typology of coordination instruments was developed and used to break them down into structural and management tools, and infer their underlying coordination mechanisms based on their design and operational features. A multitheoretical framework guided the analysis of the factors influencing the implementation dynamics and functioning of the tools. The study found that the Government of Uganda uses a range of structural and management instrument mixes mutually influencing each other and mainly based on hierarchy and network mechanisms These instruments constitute and generate the resources that structure interorganizational relationships across vertical and horizontal boundaries. The instrument mixes also create hybrid institutional configurations that generate complementary but at times conflicting influences. This study demonstrated that a contextualized examination of specific coordination tools can be enhanced by delineating the underlying institutional forms of ideal type mechanisms. Such an approach can inspire more complex analysis and comparisons of coordination instruments within and across government levels, policy domains or issues over time. Health policy and systems research needs to pay attention to the instrument mixes in government systems and their dynamic interaction across policy issues and over time.

Realist evaluation in times of decolonising global health.

Realist evaluation (RE) is a theory-driven evaluation approach inspired by scientific realism. It has become increasingly popular in the field of global health where it is often applied in low- and middle-income countries. This makes it timely to discuss RE's relationship to the emerging decolonisation of global health movement. In this short perspective, we argue that the principles and practices that underpin RE have great potential to contribute to the decolonisation endeavour. Both the focus on the inclusion of local stakeholders and the openness to the rival theories these stakeholders bring to the fore, are promising. However, in practice, we see that a lack of acknowledgement of power imbalances and different ontologies and an overreliance on Western-based theories thwart this potential. We therefore suggest that realist evaluations performed by external researchers, especially in the field of global health, should actively engage with issues of (power) inequities. This is not only the just thing to do, but will also contribute to a better understanding of the intervention and may facilitate the emancipation of the disenfranchised. One way of doing this is through the adoption of participatory (action) research methods, currently underused in realist evaluations. We finally give a short example of an evaluation that combines emancipatory and participatory practice development with a realist approach. The Afya-Tek project in Tanzania has an innovative bottom-up approach throughout the full evaluation cycle and shows the possible strength of the proposed combination to create better interventions, more empowered stakeholders, and more illuminating programme theories.
