what we do

Evidence Reviews


We understand the importance of making decisions based on the best available evidence. Evidence reviews use proven methods to establish the current state of knowledge; they use robust, transparent methods to identify and evaluate research and present relevant findings in a clear, practitioner focussed reports. 


We have a significant track record of accomplishment in conducting high quality evidence reviews having completed over 20 in recent years. We pride ourselves in our ability to distil large amounts of complex information into concise, usable and actionable reports, relevant to both policy and practitioner audiences. 

We are experts in employing systematic methods for all types of evidence reviews; all our processes are transparent, reproducible and auditable. Our search methods ensure all the relevant literature is identified. We then use a carefully designed process to select the most relevant studies and to individually appraise each piece of literature. Our accessible reports then ‘tell the story’ of the findings in a succinct form for policy and practitioner audiences.  

Our teams routinely include leading sector experts who inject their specialist expertise at key stages of the project to further enhance the quality of the final output. Using this model, we deliver high quality evidence reviews on a broad range of topics as our extensive track record shows.
