The Centre for Reviews and Dissemination (CRD) is a health services research centre based at the University of York, England. CRD was established in January 1994, and aims to provide research-based information for evidence-based medicine. CRD carries out systematic reviews and meta-analyses of healthcare interventions, and disseminates the results of research to decision-makers in the NHS. CRD produces three databases: * Database of Abstracts of Reviews of Effects (DARE) * NHS Economic Evaluation Database (NHS EED) * Health Technology Assessment Database (HTA Database)
