Protocol: What works to increase the use of evidence for policy decision-making: A systematic review.

This is the protocol for a Campbell systematic review. The objectives are as follows: Our aim is to collect, assess, and synthesise all the available empirical evidence on what works to support evidence-informed decision-making by policymakers. In doing so, we will aim to answer the following research questions: What are the impacts of interventions to support evidence-informed decision-making by policymakers? What are the factors which have influenced the impact of these interventions, and their design and implementation in low- and middle-income countries? In answering these questions, our goal is to estimate the overall impact and relative effectiveness of different interventions, identify factors or configurations of factors that support or hinder their effectiveness in low- and middle-income countries and to identify gaps and areas for future primary research.

The importance of social media users' responses in tackling digital COVID-19 misinformation in Africa.

Objective: Digital technologies present both an opportunity and a threat for advancing public health. At a time of pandemic, social media has become a tool for the rapid spread of misinformation. Mitigating the impacts of misinformation is particularly acute across Africa, where WhatsApp and other forms of social media dominate, and where the dual threats of misinformation and COVID-19 threaten lives and livelihoods.
