  • Intercalated BSc Paula Funnell p.a.funnell@qmul.ac.uk Senior Academic Liaison Librarian (Medicine and Dentistry) Searching for Information
  • Learning outcomes • To know where to look for good quality information on the web • To learn how to use key medical databases effectively
  • Search engines • Search engine = supermarket • Photo by vauvau (http://flic.kr/p/75yAAb) • Searches across many DIFFERENT things
  • Healthcare specific search engines • Search specifically across healthcare related resources • Search across good quality internet resources • Much more manageable number of results
  • 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
  • Evidence Search • 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
  • TRIP • One simple search box • Results are colour coded giving an at a glance indication of quality of information • Results vary widely - including primary research, reviews, textbooks and news www.tripdatabase.com
  • Databases • Databases – florist • Photo by stevewhis (http://flic.kr/p/a4h4RJ) • Collection of SAME thing
  • 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 Web
  • 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
  • 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
  • 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
  • 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
  • Practical • Work through the PubMed activity • Try out either the Web of Science or Scopus using the activities on QM Plus
  • 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
  • Broadening your search • Truncation – add an asterisk to the stem of a word • Injur* will search for injury, injuries, injured, injuring . . .
  • 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
  • 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
  • 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.
  • 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
