medline
MEDLINE

Multiple versions of this database

Same content but different look

Ovid = PubMed

(= PubGet)

MEDLINE and PubMed

Articles are added to PubMed by publishers

Clarifying confusing nomenclature

…then moved to MEDLINE as they are indexed (have MeSH terms added) by NLM

PubMed (database)

> 19.5million

What is MeSH?

MEDLINE (database)

> 17.8 Million

PubMed (search engine) is the tool used to search in PubMed and MEDLINE

medical subject headings mesh
Medical Subject Headings (MeSH)
  • Most important single concept of today!!
  • A “dictionary” in which you look up the best words to use in MEDLINE searches
  • Using MeSH in searches increases the number of relevant articles found by 40-60%
  • Limitations:
    • New concepts, procedures, drugs may not have a MeSH term
      • Use a Keyword (= any search term you choose that is not a MeSH term)
    • Takes time for new articles to be “indexed” for MEDLINE
      • Can miss the newest articles
two databases
Two Databases …
  • PubMed can be considered as two databases in one
    • PubMed/MEDLINE – A database of information about journal articles
    • MeSH – A dictionary of terms to use in MEDLINE
  • The most effective searching is
    • Finding the term in MeSH
    • Search with that term in MEDLINE
medline13
MEDLINE
  • Three ways to access MEDLINE at USC:
    • PubMed (USC’s version, PubMed@USC includes links to USC holdings)
      • Freely available
      • Now teaching Keck students this version of MEDLINE
    • OvidSP (includes links to USC holdings)
      • USC pays Ovid for access
      • Residents and students may not have access after USC
    • PubGet.com (see Clinician Portal for information)
create a myncbi account
Create a MyNCBI Account
  • Allows you to save you work and get back to it!
    • Save your searches
      • PubMed send you new articles about the topic as they come out
    • Save good articles in Collections
  • Let’s do it
let s try a search
Let’s try a search…
  • Does selenium supplementation prevent prostate cancer?
  • Concepts:
    • Prostate Cancer
    • Selenium Supplements
  • We want articles with both concepts
    • Would you combine the concepts with AND or OR?
    • AND
  • See one … watch a search in PubMed
you have a list of results
You have a list of results…
  • Things you can do now:
    • Look at full-text copy of articles

      • Save
      • Email
    • Add to Clipboard

  • Is oxygen inhalation therapy or triptans more effective in treating acute cluster headache?
  • In juvenile myoclonic epilepsy, would you best treat with valproate or would you choose another anticonvulsant medication?

  • Are steroids useful as part of treatment of septic shock
  • Are steroids useful as part of treatment of bacterial meningitis?
  • Do SSRIs increase risk of GI bleeding?
medline rules of thumb
MEDLINE Rules of Thumb
  • Use MeSH if available
  • 3 or fewer MeSH terms are (usually) enough
  • Focus the disease or condition
  • Subheadings
    • 3 or fewer subheadings per MeSH
    • Don’t use unless they match perfectly
  • Explode
    • Leave MeSH terms exploded
keeping up time savers
Keeping Up … Time Savers
  • Electronic table of contents (e.g., JAMA)
    • PubGet.com
  • Saved work in MEDLINE:
    • MyNCBI and/or
    • Ovid Personal Account
  • UpToDate - ”What’s New”
  • Faculty of 1000 – Medicine
  • Journal Watch
google scholar it has a role
Google Scholar…it has a role
  • If you strike out in MEDLINE…
  • Searches full text of article
    • Very sensitive – finds the needle
    • Not specific – gives you the haystack too
  • GoogleScholar – set Advanced Preferences for USC full text
