The Cochrane Library is a collection of six databases that contain different types of high-quality, independent evidence to inform healthcare decision-making.
The six databases can also be search separately via the links below:
- Cochrane Database of Systematic Reviews contains full text articles, as well as protocols focusing on the effects of healthcare. Data is evidence-based medicine and is often combined statistically (with meta-analysis) to increase the power of the findings of numerous studies, each too small to produce reliable results individually.
- Database of Abstracts of Reviews of Effects (DARE) includes abstracts of published systematic reviews on the effects of health care from around the world, which have been critically analyzed according to a high standard of criteria. This database provides access to quality reviews in subjects for which a Cochrane review may not yet exist.
- Cochrane Controlled Trials Register (CENTRAL) is a bibliography of controlled trials identified by contributors to the Cochrane Collaboration and others, as part of an international effort to hand search the world's journals and create an unbiased source of data for systematic reviews.
- The Cochrane Methodology Register (CMR) is a bibliography of publications which report on methods used in the conduct of controlled trials. It includes journal articles, books and conference proceedings; these articles are taken from the MEDLINE database and from hand searches. The database contains studies of methods used in reviews and more general methodological studies which could be relevant to anyone preparing systematic reviews. CMR records contain the title of the article, information on where it was published (bibliographic details), and in some cases, a summary of the article. CMR is produced by the UK Cochrane Centre, on behalf of the Cochrane Methodology Review Group.
- The 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.
- The Health Technology Assessments (HTA) database provides details of completed and ongoing health technology assessments (studies of the medical, social, ethical and economic implications of healthcare interventions) from around the world. The aim of the database is to improve the quality and cost-effectiveness of health care. In addition to systematic reviews, HTA contains ongoing and completed research based on trials, questionnaires and economic evaluations.
