  1. Advanced PubMed Searchingfor First-year PT Master Students Min-Lin E Fang, MLIS Education and Information Consultant for Nursing and Social and Behavioral Sciences

  3. Objectives By the end of this seminar you will be able to: • Perform a subject search using Medical Subject Headings • Use limits to narrow a PubMed search • Use the Clinical Queries feature to search for clinical research in PubMed@UCSF • Use the Display options • Print and download citations • Link from PubMed citations to full text articles

  4. PubMed MEDLINE • National Center for Biotechnology Information (NCBI) • Approximately 14 million references to the published journal literature • 1950 (OLDMEDLINE) to present in one database • Incorporates all or part of CANCERLIT, HealthSTAR, AIDSLINE, HISTLINE, BIOETHICSLINE, SPACELINE • Links to full text articles

  5. Special URL: http://www.library.ucsf.edu/db/pubmed/ UC-eLinks Links to UCSF full text journals Links to UCSF Library Catalog to check whether UCSF owns a journal and get call no Links to Melvyl Catalog to check which other UC campuses own a journal Request articles not owned by UCSF from other UC campuses Copy and paste PubMed @UCSF

  6. Boolean Operators • OR (use to join synonyms) • Vitamin C OR Ascorbic Acid • doctors OR physicians • tumor OR tumour • injuries OR accidents • AND (use to combine concepts) • Vitamin C AND cancer • doctors AND managed care • color AND vision • injuries AND automobiles

  7. Boolean AND

  8. Boolean OR

  9. MeSH Translation Table Journals Translation Table Author Translation Table Author Index Search All Fields Forced phrase searching in quotes “” Explode is automatic Truncation (*) turns off mapping Search field tags are available [title] or [ti] Boolean operators processed left to right Search Term Mapping

  10. Why use MeSH? • If you use two or more words in a keyword search there is no guarantee that they will be linked. • MeSH headings are an efficient way to find information on “concepts” or topics where authors use different language to discuss the same ideas. • For example: Keyword search physical therapy Microneedles and other physical methods for overcoming the stratum corneum barrier for cutaneous gene therapy.

  11. When to use keyword search? • Recent publications (in process) • Records supplied by publishers • New phenomenon

  12. Locating MeSH • Do a Title word search; display results in Citation format; identify MeSH OR • Search the MeSH database • Scope Note • Subheadings • Major Topics • Explode

  13. Clinical Queries • Etiology • Diagnosis • Therapy • Prognosis • Clinical prediction guides Example: 1. Studies on the treatment of chronic low back pain 2. Systematic reviews on the treatment of chronic low back pain

  14. Clinical Queries: Clinical Studiestreatment of chronic low back pain

  15. Clinical Queries: Systematic Reviewsphysical therapy to treat chronic low back pain

  16. Topic Search Technique • Separate query into main search concepts • Identify an appropriate MeSH term for each concept • Combine search terms using boolean operators: AND, OR, NOT • Apply Limit options • Refine search

  17. Limit Options • Language (English) • Human or animal studies • Dates • Age groups (All child, adolescent, aged…) • Publication types (Meta-Analysis, ROC, Review, Evaluation studies…) • Subsets (Core clinical journals…) • Major concept

  18. Exercise 1 Meta-analyses on the efficacy of exercise therapy for low back pain Concept: exercise therapy low back pain Publication type: meta analysis

  19. Exercise 1: Search Steps • Search MeSH database for each concept. - Click on MeSH Database on the left- hand column. - Enter exercise therapy and click on Go. - Check exercise therapy. Go to Send to box and select Search box with AND. - Enter low back pain and click on Go. - Check low back pain and select Search box with AND. - Click on PubMed Search. - Click on Limits, select meta-analysis, and click on Go.

  20. Exercise 1 –cont. • Search MeSH Database for each concept.

  25. Exercise 2 - Prevention of danceinjuries

  26. Exercise 3 • Gait training for stroke patients

  27. Exercise 4 • Treatment outcomes of using physical therapy to treat frozen shoulder (bursitis)

  28. Obtaining Journal Articles • UC-eLinks • Link to full text article (UCSF subscription) • Check UCSF Catalog and Melvyl for journal location (print and electronic) • Request articles from journals not owned by UCSF • Interlibrary Services http://www.library.ucsf.edu/info/circ/ilb.html • Document Express: Obtain journal articles owned at UCSF for a minimal fee
