Stigma reduction in relation to HIV test uptake in low- and middle-income countries: a realist review

Background

This realist review was conducted to understand how stigma is reduced in relation to HIV test uptake in low- and middle-income countries (LMICs).

Methods

A systematic search of eight databases resulted in 34 articles considered for synthesis. Data synthesis was guided by a preliminary programme theory and included coding the meaning units to develop themes or intervention pathways that corresponded to context-mechanism-outcome configurations.

Results

We found that the interventions produced an effect through two pathways: (a) knowledge leads to changes in stigmatizing attitudes and increases in HIV test uptake and (b) knowledge and attitudes lead to changes in stigmatizing behaviours and lead to HIV test uptake. We also found one competing pathway that illustrated the direct impact of knowledge on HIV test uptake without changing stigmatizing attitudes and behaviour. The identified pathways were found to be influenced by some structural factors (e.g., anti-homosexuality laws, country-specific HIV testing programmes and policies), community factors (e.g., traditional beliefs and practices, sexual taboos and prevalence of intimate partner violence) and target-population characteristics (e.g., age, income and urban-rural residence).

Conclusions

The pathways and underlying mechanisms support the adaptation of intervention strategies in terms of social context and the target population in LMICs.

Role of institutional entrepreneurship in building adaptive capacity in community-based healthcare organisations: realist review protocol

INTRODUCTION

Over the past 3 decades, there has been a substantial shift to the marketisation of government-funded health services. For organisations traditionally buffered from the competitive pressures of for-profit enterprises, such as community-based organisations, this means developing the capacity to adapt to competitive tendering processes, shifting client expectations, and increasing demands for greater accountability. Drawing on ideas of institutional entrepreneurship, we believe that attempts to build adaptive capacity require the transformation of existing institutional arrangements. Key in this may be identifying and fostering institutional entrepreneurs--actors who take the lead in being the impetus for, and giving direction to, structural change. This study focuses on the strategies used by institutional entrepreneurs to build adaptive capacity in the community-based healthcare sector.

METHODS AND ANALYSIS

The research will use an adapted rapid realist review. The review will find underlying theories that explain the circumstances surrounding the implementation of capacity-building strategies that shape organisational response and generate outcomes by activating causal mechanisms. An early scoping of the literature, and consultations with key stakeholders, will be undertaken to identify an initial programme theory. We will search for relevant journal articles and grey literature. Data will be extracted based on contextual factors, mechanisms and outcomes, and their configurations. The analysis will seek patterns and regularities in these configurations and will focus on confirming, refuting or refining our programme theory.

ETHICS AND DISSEMINATION

The study does not involve primary research and, therefore, does not require formal ethical approval. However, ethical standards of utility, usefulness, feasibility, propriety, accuracy and accountability will be followed. The results will be written up according to the Realist and Meta-Review Evidence Synthesis: Evolving Standards guidelines. Once completed, findings will be published in a peer-reviewed journal.

Effect of stigma reduction intervention strategies on HIV test uptake in low- and middle-income countries: a realist review protocol

BACKGROUND

Several stigma reduction intervention strategies have been developed and tested for effectiveness in terms of increasing human immunodeficiency virus (HIV) test uptake. These strategies have been more effective in some contexts and less effective in others. Individual factors, such as lack of knowledge and fear of disclosure, and social-contextual factors, such as poverty and illiteracy, might influence the effect of stigma reduction intervention strategies on HIV test uptake in low- and middle-income countries. So far, it is not clearly known how the stigma reduction intervention strategies interact with these contextual factors to increase HIV test uptake. Therefore, we will conduct a review that will synthesize existing studies on stigma reduction intervention strategies to increase HIV test uptake to better understand the mechanisms underlying this process in low- and middle-income countries.

METHODS

A realist review will be conducted to unpack context-mechanism-outcome configurations of the effect of stigma reduction intervention strategies on HIV test uptake. Based on a scoping review, we developed a preliminary theoretical framework outlining a potential mechanism of how the intervention strategies influence HIV test uptake. Our realist synthesis will be used to refine the preliminary theoretical framework to better reflect mechanisms that are supported by existing evidence. Journal articles and grey literature will be searched following a purposeful sampling strategy. Data will be extracted and tested against the preliminary theoretical framework. Data synthesis and analysis will be performed in five steps: organizing extracted data into evidence tables, theming, formulating chains of inference from the identified themes, linking the chains of inference and developing generative mechanisms, and refining the framework.

DISCUSSION

This will be the first realist review that offers both a quantitative and a qualitative exploration of the available evidence to develop and propose a theoretical framework that explains why and how HIV stigma reduction intervention strategies influence HIV test uptake in low- and middle-income countries. Our theoretical framework is meant to provide guidance to program managers on identifying the most effective stigma reduction intervention strategies to increase HIV test uptake. We also include advice on how to effectively implement these strategies to reduce the rate of HIV transmission.
