  • 4. PubMed Searching For Clinical Decisionmaking
    • Selecting MeSH Terms
    • Clinical Queries Searching
    • Systematic Review Searching
    • Quality, Authority & Credibility: Chain of Trust
  • 5. PubMed
  • 6. PubMed: Services
    • You should already know:
      • Single Citation Matcher
      • Journals Database
    • Today:
      • MeSH Database
      • Clinical Queries
    • Next Class:
      • My NCBI
    • On Your Own:
      • Special Queries
  • 7. PubMed: MeSH: Why MeSH?
    • Why use MeSH?
      • PubMed’s easy search interface makes assumptions about what you want, and interprets what you search
      • Using MeSH makes your search more precise and specific, meaning you are more likely to get what you really want
      • Using MeSH provides consistency and control
  • 8. PubMed: MeSH: Why MeSH?
    • Assumptions: Example:
    • Root canal perforation (200 results)
  • 9. PubMed: MeSH: Why MeSH?
    • Assumptions: Example:
    • Root canal perforations (196 results)
  • 10. PubMed: MeSH: Why MeSH?
    • Assumptions: Example: Root canal perforations
      • “ Root canal” became “dental pulp cavity”
        • Did you mean the anatomical area, or the procedure?
      • Perforations or perforation retrieved different results -- PubMed did not automatically pluralize.
        • Just when you assume it assumes what you assume, it doesn’t …
  • 11. PubMed: MeSH Database
  • 12. PubMed: MeSH Database
    • Example: Caries
    • Suggestions
    • Other terms
    • Definitions
    • Year Introduced
  • 13. PubMed: MeSH Database
    • Example: Caries: Result #3
    • Example: Caries: Result #6
  • 14. PubMed: MeSH Database
    • Full entry for Dental Caries
  • 15. PubMed: MeSH Database: Entry Terms
    • MeSH term is equivalent to words and phrases listed as “Entry Terms”
    • These terms, when appearing in an abstract, will result in this MeSH term being assigned.
  • 16. PubMed: MeSH Database: Cross References
    • MeSH entry will also provide “See Also” terms.
    • These suggest alternate MeSH terms that you may wish to use instead of or in addition to the term currently selected.
  • 17. PubMed: MeSH Database: Tree Display
    • Here is your first real clue that “Tooth Demineralization” should usually be used for searching “Caries”.
  • 18. PubMed: MeSH Database: Send to Search
    • From MeSH Browser, you can send selections directly to the Search box.
    • Use the “Send-to” drop-down menu on the far right.
  • 19. PubMed: MeSH Database: Send to Search 2
  • 20. PubMed: MeSH Database: Send to Search 3
    • See result in expert search form in the Search Box.
    • Click “Search PubMed”
  • 21. PubMed: Clinical Queries
    • What Clinical Queries do for you:
      • Fast
      • Focused (not too many articles)
      • High-Quality (original research)
    • This means you make a clinical decision or recommendation without having to dig through many citations looking for the “good stuff”
  • 22. PubMed: Clinical Queries
    • Screenshot of opening clinical queries screen
  • 23. PubMed: Clinical Queries: Categories
  • 24. PubMed: Clinical Queries: Caries Example 1
  • 25. PubMed: Clinical Queries: Caries Example 2
  • 26. PubMed: Clinical Queries: Caries Example 3
  • 27. PubMed: Clinical Queries: Caries Example 4
  • 28. PubMed: Clinical Queries: Root Canal Example 1
  • 29. PubMed: Clinical Queries: Root Canal Example 2
  • 30. PubMed: Clinical Queries: Root Canal Example 3
  • 31. PubMed: Clinical Queries
    • What PubMed is really doing:
      • (("dental pulp cavity"[MeSH Terms] OR root canal[Text Word]) AND perforation[All Fields]) AND (randomized controlled trial[Publication Type] OR (randomized[Title/Abstract] AND controlled[Title/Abstract] AND trial[Title/Abstract]))
  • 32. PubMed: Systematic Reviews
    • Located on same page as Clinical Queries, directly below.
  • 33. PubMed: Systematic Reviews: Example
    • Tooth demineralization:
    • Note: Root canal performation = 0 systematic Reviews
  • 34. Chain of Trust / Levels of Evidence Tool
    • CHAIN =
    • Candor
    • Honesty
    • Accountability
    • Information Quality
    • Neighborly
    • TRUST =
    • Timeliness
    • Relevant
    • Unbiased
    • Scope
    • Trustworthy
  • 35. Chain of Trust / Levels of Evidence Tool
    • CHAIN =
  • 36. Chain of Trust / Levels of Evidence Tool
    • TRUST =
  • 37. Chain of Trust / Levels of Evidence Tool
    • Scoring = 0 to 5
    • 1 = bad, 5 = good, 0 = not applicable
  • 38. Chain of Trust / Levels of Evidence Tool
    • “ Informal” or dated sources (not original research or not peer reviewed publication)
  • 39. Chain of Trust / Levels of Evidence Tool
    • Original research and/or peer reviewed publication
    • SOURCE: Medical Research Library of Brooklyn

  • 41. Assignment:
    • See provided case study
      • Select 2-4 MeSH Terms
      • Create a “Clinical Queries” search (screenprint)
      • Create a systematic review search for same topic (screenprint)
    • Select bottom article citation listed on either the CQ or SR search
      • Evaluate article citation & abstract with Chain of Trust tool
      • State whether you would read the article or not.
