  5. Norris Medical Library—Access and Overview of Resources

  6. Norris Medical Library (usc.edu/nml) • Proxy server (don’t use VPN) (http://libproxy.usc.edu/login ) • Log in with USC email information • User name (email address up to @) • Password • Bookmark Norris Library homepage • Start information hunting here as you will have full text access to everything USC purchases

  7. Clinician’s “Portal” • “Everything” you need in one place • If there are other things you want in this location … let me know

  8. Troubleshooting • If you can’t get to something you want … • Let us know and we will fix it for you • (We have one person at the library devoted to fixing links to publisher’s websites)

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

  10. 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

  11. 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

  12. 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

  13. 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)

  14. 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

  15. 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

  16. You have a list of results… • 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. Your turn…Suggested searches • 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 or too few?

  19. 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

  20. Additional Notes

  21. 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

  22. Alternatives to UpToDate • Norris homepage

  23. 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

  24. Thank you! • Please feel free to contact me (or any of the librarians at Norris Library) with any information questions you have! • Norris Website (http://www.usc.edu/nml)
