Evidence Aid is an international platform that was formed out of the need to deliver time sensitive access to systematic reviews for use in the event of disasters and other humanitarian emergencies. The method of using systematic reviews (a collection of available evidence on any given topic) is to provide evidence for use by policy makers, clinicians, regulators, clinicians and even the general public who benefit when these materials are easy to understand and are accessible. The vision of Evidence Aid is to create and satisfy an increasing demand for evidence to improve the impact of humanitarian aid by stimulating the use of an evidence-based approach. Evidence Aid was founded in 2004. It is currently a project that is housed by the Cochrane Collaboration and Queens University Belfast.
