Introduction: This paper explores the development of the Realist Implementation Action Research Lab (RIAL), a participatory learning site aimed at addressing health disparities among Adivasi communities in India. Despite national health improvements, Adivasis face significant health inequities. RIAL employs a realist-inspired, theory-driven design...
As a theory-driven evaluation design grounded in the critical realism philosophy, realist evaluation relies on eliciting the assumptions of stakeholders about how programmes are expected to produce outcomes. Little is known about key principles for involving stakeholders in realist evaluations. In this scoping review of realist evaluation studies,...
There is a growing interest in studying and unpacking implementation of policies and programmes as it provides an opportunity to reduce the policy translation time lag taken for research findings to translate to policies and get implemented and understand why policies may fail. Realist evaluation is a theory-driven approach that embraces complexity...

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...
Realist evaluation is in essence a theory-building and testing approach. We argue that in practice, the theory-building potential of realist evaluation, review and research is not fully exploited in the field of global health. Our assumption is that the Structure-Agency-Culture explanatory framework of critical realist Margaret Archer could stimula...
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 worke...
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...
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.

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 t...
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...
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 explori...
HIV positive key population (KP) often face health system and social barriers to HIV care. KP include sex workers, men who have sex with men, persons who inject drugs, transgender people, and people in prisons and other closed settings. Community-based ART service delivery (CBART) has the potential to increase access to antiretroviral treatment (AR...
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 persp...

Background: An estimated 7.9 million people were living with HIV in South Africa in 2017, with 63.3% of them remaining in antiretroviral therapy (ART) care and 62.9% accessing ART. Poor retention in care and suboptimal adherence to ART undermine the successful efforts of initiating people living with HIV on ART. To address these challenges, the ant...
Global strategies and commitments for sexual and reproductive health and rights (SRHR) underscore the need to strengthen rights-based accountability processes. Yet there are gaps between these ambitious SRHR rights frameworks and the constrained socio-political lived realities within which these frameworks are implemented. This paper addresses thes...
Lehoux and colleagues plea for a health systems perspective to evaluate innovations. Since many innovations and their scale-up strategies emerge from processes that are not (centrally) steered, we plea for any assessment with a dynamic, instead of a sequential, approach. We provide further guidance on how to adopt such dynamic approach, in order to...
In this article, I set out to capture the dynamics of two streams within the field of global health research: realist research and medical anthropology. I critically discuss the development of methodology and practice in realist health research in low- and middle-income countries against the background of anthropological practice in global health t...
