  2. 2. Agenda <ul><li>Introduction </li></ul><ul><li>Goals and structure of the workshop </li></ul><ul><li>What is PubMed and why to us it </li></ul><ul><li>Review of simple search in PubMed </li></ul><ul><li>Review of advanced search in PubMed </li></ul><ul><li>myNCBI – introduction </li></ul><ul><li>Questions </li></ul>
  3. 3. Goals of the Workshop <ul><li>Understand what is PubMed and how it works </li></ul><ul><li>Understand the limitations of simple keyword searches </li></ul><ul><li>Comprehend some of the powerful techniques using Medical Subject Headings options </li></ul>
  4. 4. What is PubMed <ul><li>Created and maintained by the U.S. National Library of Medicine , </li></ul><ul><li>Over 17 million citations </li></ul><ul><li>From almost 5,000 health and life science journals </li></ul><ul><li>Goes back to 1950s </li></ul><ul><li>Updated daily </li></ul><ul><li>Mostly bibliographic information </li></ul><ul><li>1 million free full text article via PubMed Central (PMC) - http:// www.pubmedcentral.nih.gov / </li></ul>
  5. 5. How to access PubMed <ul><li>www.pubmed.gov </li></ul><ul><li>Google PubMed  </li></ul>
  6. 6. Simple search - keywords <ul><li>For a quick and dirty “Google-style” search, just type your keywords into PubMed’s Search box </li></ul><ul><li>Let’s try to find some literature on effectiveness of continuous passive motion (CPM) therapy for knee replacement rehab </li></ul>
  7. 7. Simple search - keywords <ul><li>PubMed located 40 articles (from 17 million) that mention all words we typed in the search box. </li></ul><ul><li>This is a good quick and dirty search for such a small topic… </li></ul><ul><li>However, we don’t want those articles that just mention our keywords; we want article that focus on effectiveness of CPM for knee replacement rehab! </li></ul><ul><li>Aha…for that, we need to understand Medical Subject Headings </li></ul><ul><li>http://www.nlm.nih.gov/mesh/ </li></ul>
  8. 8. Introducing MeSH <ul><li>Medical Subject Headings (MeSH): </li></ul><ul><ul><li>U.S. National Library of Medicine's controlled vocabulary </li></ul></ul><ul><ul><li>Access MeSH from the left-hand sidebar </li></ul></ul>Note: Controlled vocabularies bring all variations of a concept under one “approved” term or phrase which makes searching more efficient (Example: Neoplasm is the controlled term in MeSH for variations and synonyms of cancer, tumors, etc.)
  9. 9. Using MeSH <ul><li>To locate an appropriate MeSH for your term, search PubMed MeSH sub-database </li></ul><ul><li>Let’s try to see what PubMed uses for knee replacement </li></ul><ul><ul><li>Go to MeSH and type your terms in… </li></ul></ul>
  10. 10. Using MeSH <ul><li>The MeSH term is Arthroplasty, Replacement, Knee </li></ul><ul><li>R ead the blurb to decide whether this MeSH term is relevant </li></ul><ul><li>Select one or more subheadings if appropriate – these will narrow your search down to more specific areas of research </li></ul>
  11. 11. Using MeSH <ul><li>Steps involved: </li></ul><ul><ul><li>First, we select a proper MeSH (click the checkbox) </li></ul></ul><ul><ul><li>We select “ Search Box with And ” from the “ Sent to” drop down menu </li></ul></ul>
  12. 12. Using MeSH <ul><ul><li>Then, we click on PubMed search button to search all 17 million articles for our selected MeSH topic </li></ul></ul><ul><ul><li>There are 282 articles that are about knee replacement rehab in PubMed </li></ul></ul>
  13. 13. Using MeSH <ul><li>Let’s do the same with our second term – CPM therapy </li></ul><ul><ul><li>The term is > Motion Therapy, Continuous Passive </li></ul></ul><ul><ul><li>355 citations are retrieved </li></ul></ul>
  14. 14. Search history <ul><li>See your last searches under “History” tab </li></ul><ul><ul><li>Alive for eight (8) hours only </li></ul></ul>
  15. 15. Combine results <ul><li>For both CPM therapy and knee replacement rehab use AND search operator </li></ul><ul><li>Only 21 articles retrieved (down from 41 at the beginning) – more precise searches, thanks to MeSH!! </li></ul>
  16. 16. Limits <ul><li>Limit to EBP results, age groups, language, focus on specific profession, etc. from the Limits tab </li></ul>
  17. 17. Limits <ul><li>My limits: </li></ul>
  18. 18. Limits <ul><li>Limits appear in a yellow bar </li></ul><ul><li>Now we have only three (3) studies – Wow! </li></ul>
  19. 19. Display <ul><li>To view Abstracts, etc., change format from Display drop-down menu </li></ul>
  20. 20. Sort <ul><li>Sort your results: </li></ul><ul><ul><li>Publication Date </li></ul></ul><ul><ul><li>Author’s name </li></ul></ul><ul><ul><li>Journal </li></ul></ul>
  21. 21. Related Articles <ul><li>Click to view closely related articles </li></ul><ul><li>Note that you loose everything you applied so far: MeSH, limits, etc. </li></ul>
  22. 22. Clipboard <ul><li>Store your selected articles in Clipboard for eight (8) hours </li></ul><ul><li>Email, print, and do more with your articles after sending them to the Clipboard, via “ Send To” drop down menu </li></ul>
  23. 23. Find a citation <ul><li>If you know what citation you are looking for, the easiest way to locate it in PubMed would be using “ Single Citation Matcher ” </li></ul>
