  4. 4. Databases • Vast collections of references of published research • Filters can be applied to narrow results down • Searches can be combined and saved for future use • References can be imported to EndNote
  5. 5. Clinical Summaries • NOT source of primary research • Evidence has been read and summarised • Information presented in a short paragraph, or as little as a bullet point • Up-to-date and accurate sources of clinical knowledge
  6. 6. Categories of information resource You have each been allocated a resource from one of the different categories. Use the worksheet to guide you in familiarising yourself with the resource and be ready to report back to the group about it.
  7. 7. Categories of information resource Web search engines Clinical Summaries • • • • • Clinical Evidence • Clinical Knowledge Summaries • Evidence Based Medicine Google Scholar Medline Plus Evidence Search Trip Online Databases • Medline (PubMed) • Web of Science • The Cochrane Library
  8. 8. Web search engines • Specifically ones which search across a range of good quality internet resources • Several medicine specific search engines • Provide huge variety of results • Beware quality of information. – Is it evidence based? – Has it been critically appraised?
  9. 9. TRIP database • One simple search box • Results colour coded by format of information found giving an at a glance indication of quality of information • Results vary widely - including primary research, reviews, textbooks and news www.tripdatabase.com
  10. 10. Google scholar • Will generate more academic results than Google • Can be limited by date • No indication of quality of information http://scholar.google.co.uk
  11. 11. Medline Plus • US National Institutes of Health's web site for patients and their families and friends • Designed to provide up-to-date healthcare information in understandable language • Also provides links to the latest medical research www.nlm.nih.gov/medlineplus/
  12. 12. Evidence Search • Searches across all electronic resources provided by NHS • Results can be filtered – Type of information – Areas of interest – Sources www.evidence.nhs.uk
  13. 13. Databases • Vast collections of references of published research • Filters can be applied to narrow results down • Searches can be combined and saved for future use • References can be imported to EndNote
  14. 14. The Cochrane Library • High quality systematic reviews • Full text of Cochrane review • Abstracts of other systematic reviews and clinical trials www.thecochranelibrary.com

  19. 19. Clinical Evidence • Current evidence-based reviews of treatments (currently 260) • Clinical information displayed in a question and answer format • Links to current evidence and guidelines • Additional links provided to patient information and BNF www.clinicalevidence.com
  20. 20. Evidence-Based Medicine • Experts critically appraise clinically relevant articles • Produce summaries of content • Comment on clinical applicability • Publishes articles relevant to study and practice of EBM ebm.bmj.com
  21. 21. Summary • Use specialist search engines to search across a wide range of good quality web resources • Use databases to find academic research articles, both primary research as well as review articles • Use clinical summaries for a quick overview of the best available evidence
