  • 3. Useful web pages • Search engines that search specifically across good quality health related resources • Websites with a public health focus
  • 4. NHS Evidence • Easy to use • Searches across high-quality healthcare specific resources • Provided and managed by NICE • Wide range of filters allow you to narrow down your search e.g. by type of information or date of publication www.evidence.nhs.uk

  • 7. World Health Organisation • Provides leadership on global health matters • Articulates ethical and evidence-based policy options • Monitors the health situation and assesses trends • Links to statistics and other publications www.who.int
  • 8. 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
  • 9. MEDLINE (PubMed) • PubMed is a search interface for the MEDLINE database • Database of references and abstracts of journal articles • Covers the broad field of biomedicine • Special QM PubMed address for easier full-text access www.ncbi.nlm.nih.gov/entrez/query.fcgi?otool=igbqmullib
  • 10. Web of Science • Part of ISI Web of Knowledge • Contains: – Science Citation Index – Social Sciences Citation Index – Arts and Humanities Citation Index • Need to log in off campus www.webofknowledge.com
  • 11. Scopus • World’s largest abstract and citation database • Search across a range of subject areas • Includes Medline coverage • Need to log in off campus www.scopus.com
  • 12. The Cochrane Library • High quality systematic reviews • Already been critically appraised • Full text available • Also contains abstracts of other systematic reviews and clinical trials www.thecochranelibrary.com
  • 13. Practical • Work through the PubMed activity on QM Plus • In pairs: one work through Web of Science activity and the other Scopus • Discuss your findings with your partner
  • 14. Broadening your search • An OR search – combine two synonyms to give a larger number of results • Child health OR paediatrics will search for any articles containing one or both of the terms
  • 15. Broadening your search • Truncation – add an asterisk to the stem of a word • Injur* will search for injury, injuries, injured, injuring . . .
  • 16. Narrowing your search • An AND search – combine two elements of your search question to give a smaller number of results • Asthma AND children will search for any articles containing both of the terms
  • 17. Narrowing your search • Phrase searching – enclose phrase within quotation marks • “diabetes mellitus” will return results where diabetes and mellitus appear side by side in the title or abstract
  • 18. Subject headings & thesaurus terms • E.g. MeSH terms in PubMed • Alternative to keyword searching • Fixed set of terms assigned to define the main focus of an article • Each article “tagged” with several headings • Heading not necessarily a word that appears in title or abstract • PubMed automatically searches MeSH terms. Check the search details box.
  • 19. 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
