NHS Economic Evaluation DatabaseThe NHS Economic Evaluation Database (NHS EED) assists decision-makers in the world of professional health care by providing information on the costs and effects of drugs, treatments and procedures. Economic evaluations - the cost-benefit analysis of two or more different medical treatments - from around the world are systematically identified, described and appraised for quality while their relative strengths and weaknesses are explored and highlighted. The database contains over 6,000 abstracts of quality-assessed economic evaluations and more than 21,000 total records. NHS EED is produced by the Centre for Reviews and Dissemination (CRD) at the University of York, UK.
