Finding research evidence: The Centre for Reviews and Dissemination

Centre for Reviews and Dissemination. University of York, York, UK.

Description

The Centre for Reviews and Dissemination (CRD) provides an online repository of current, high quality research evidence on health and public health issues. Funded by the UK National Institute for Health Research at University of York, the CRD databases identify and critically summarize systematic reviews and economic evaluations and provide a comprehensive listing of in-progress and published health technology assessments. The databases play a key role in identifying and appraising research evidence to promote and facilitate evidence-informed decision making.


The CRD databases are updated daily and provide professionals with access to:

  • Quality assessed systematic reviews
  • Economic evaluations
  • Health technology assessments
  • Summaries of all Cochrane reviews and protocols
  • Summaries of Campbell reviews
  • A prospective register of systematic reviews

Steps for Using Method/Tool

The Centre for Reviews and Dissemination (CRD) databases include:

  • DARE (Database of Abstracts of Reviews of Effects): This database contains over 9,000 quality assessed systematic reviews on health interventions, health services and social determinants of health.
  • NHS EED (NHS Economic Evaluation Database): With over 11,000 economic evaluations of health interventions, NHS EED includes cost-benefit, cost-utility and cost-effectiveness analyses.
  • HTA Database: The HTA Database contains over 10,000 summaries of completed and in-progress health technology assessments, which are typically only available from individual funding agencies.
  • PROSPERO: International prospective register of systematic reviews (Booth et al., 2012). Launched in Feb 2011, PROSPERO aims to reduce duplication of systematic reviews and increase transparency of systematic review methods. PROSPERO currently includes systematic reviews of evidence with health-related outcomes, with 200 records of systematic reviews being conducted in 33 countries.

Users can search the CRD databases using the following enhanced features:

  • Search options (quick search, browse, advanced search and MeSH terms
  • Search results options
  • Search strategies
  • Integrated PubMed search
  • Select personal preferences through free registration to the site (i.e., receive email alerts; access saved searches; import search strategies)

The CRD databases can be directly accessed at http://www.crd.york.ac.uk/CRDWeb/

CRD database content can also be accessed via The Cochrane Library, NHS Evidence , the Trip Database, the Virtual Health Library, Health Systems Evidence, SUMSearch and the Knowledge Network of NHS Scotland. DARE abstracts are also available in PubMed Health.

Evaluation

The critical abstracts available in DARE and NHS EED are written and checked by experienced researchers and health economists. There is no quality assessment or peer review of the information contained in the HTA database or PROSPERO.

These summaries are written by the NCCMT to condense and to provide an overview of the resources listed in the Registry of Methods and Tools and to give suggestions for their use in a public health context. For more information on individual methods and tools included in the review, please consult the authors/developers of the original resources.
