9 Multiple versions of this database Same content but different look Ovid = PubMed (= PubGet)

10 PubMed (search engine) is the tool used to search in PubMed and MEDLINE MEDLINE (database) > 17.8 Million Articles are added to PubMed by publishers MEDLINE and PubMed PubMed (database) > 19.5million …then moved to MEDLINE as they are indexed (have MeSH terms added) by NLM Clarifying confusing nomenclature What is MeSH?

11  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

12  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

13  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)

14  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 do it

15  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 PubMedPubMed

16  Things you can do now:  Look at full-text copy of articles ▪ Print ▪ Save ▪ Email  Add to Clipboard  Save to Collections  Save your search ▪ Have new articles about your topic sent to you

17  Prevention of DVT in total knee replacement?  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?  Is Guillain-Barre syndrome best treated with plasma exchange or intravenous immunoglobulin (IVIG) therapy?  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?

18 Too many resultsToo few results MeSH termsAdd another MeSH term Remove a MeSH term SubheadingsAdd subheadingsRemove subheadings MajorMesh to MajrMajr to MeSH LimitsAdd limitsRemove limits

19  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
