  1. Literature searching A literature search identifies relevant information sources that are used to answer clinical questions

  2. The objective of literature searches • Primarily to find journal articles • Other useful sources: • Books, conference proceedings, book chapters, theses, government documents, and websites Evidence-based Chiropractic

  3. Defined searches are a must • Because of the vastness of some databases, searching can be a daunting task • e.g., PubMed lists 4,800 biomedical journals • More than 15 million citations • Vague searches may produce an unmanageable number of articles • Searching PubMed for “headache”  37,147 Evidence-based Chiropractic

  4. Search and retrieval systems • Databases can be searched quickly and easily when focused search strategies are utilized • The best results occur when the search is carefully planned in advance • Less likely to miss important articles • A great deal of time can be saved Evidence-based Chiropractic

  5. Databases • A database is a collection of data that is organized in such a way that it is quick and easy to search for and retrieve specific information using a computer • Databases used in EBP contain bibliographic data from journal articles, books, reviews, etc. • Can be accessed from a remote source using an Internet connection Evidence-based Chiropractic

  6. Databases are organized • Fields • Single bits of information • e.g., title, author, journal name etc. • Records • Collections of fields • e.g., the complete citation • Files • Groups of records Evidence-based Chiropractic

  7. Example PubMed record Authors Title of article Lisi AJ, Cooperstein R, Morschhauser E. An exploratory study of provocation testing with padded wedges: can prone blocking demonstrate a directional preference? J Manipulative Physiol Ther. 2004 Feb 27 (2) 103-8 Name of journal Year & month Volume Issue Pages Evidence-based Chiropractic

  8. To search a database • Enter specific terms that correspond to any of the fields in a record • Author names • Words found in the title • The journal’s volume and issue numbers • Most databases also permit text word searches that look for terms used in the abstract or list of key words Evidence-based Chiropractic

  9. Narrow down the search • Enter combinations field items • For instance • A PubMed search using the term “low-back” produces more than 12,500 citations • When “low-back” is combined with “treatment,” 7,869 citations result • When both terms are combined with “manipulation,” the search results are narrowed down to 508 citations Evidence-based Chiropractic

  10. Databases essential to EBP • There are numerous databases to choose from • Each database has a specific emphasis • Consequently one must be familiar with several of them to perform a complete search • Especially pertaining to chiropractic • The following are of interest to chiropractic and CAM practitioners Evidence-based Chiropractic

  11. PubMed • Includes over 15 million citations • Citations are from MEDLINE and additional life science journals • MEDLINE alone has nearly 13 million records from 1966 to the present. • Includes links to many full text articles and other related resources • http://PubMed.gov Evidence-based Chiropractic

  12. Evidence-based Chiropractic

  13. Index Medicus • The online counterpart of Index medicus is MEDLINE • Vol. 41, 2000 was the last printed edition of Index medicus • Is an extensive list of journals that is compiled by the National Library of Medicine (4,959 listed in 2006) • PubMed provides free Internet access to this vast collection of information Evidence-based Chiropractic

  14. CAM on PubMed • Searches the PubMed database to locate CAM-related citations • Can be accessed from PubMed by choosing “Limits” and then “Complementary Medicine” from the “Subsets” menu • There are over 270,000 citations in the PubMed CAM subset • http://www.nlm.nih.gov/nccam/camonpubmed.html Evidence-based Chiropractic

  15. To get to CAM on PubMed Select Select Evidence-based Chiropractic

  16. Manual Alternative and Natural Therapy Index System (MANTIS) • Addresses all areas of alternative medical literature • References from more than 1,400 journals • The largest index of peer reviewed articles for several disciplines including • Chiropractic, osteopathy, homeopathy, and manual medicine • http://www.healthindex.com Evidence-based Chiropractic

  17. Evidence-based Chiropractic

  18. Index to Chiropractic Literature (ICL) • Indexes all chiropractic peer-reviewed journals cover-to-cover, and others topically • ICL is indexed by the Chiropractic Library Consortium, which is a group of health science librarians from chiropractic colleges throughout the world • http://www.chiroindex.org Evidence-based Chiropractic

  19. Evidence-based Chiropractic

  20. Cumulative Index to Nursing and Allied Health (CINAHL) • Covers nursing and allied health literature from 1982 to the present • Includes citations from 2,593 journals • Also covers biomedicine, alternative and complementary medicine, consumer health and health sciences librarianship • http://www.cinahl.com Evidence-based Chiropractic

  21. Evidence-based Chiropractic

  22. AMED • Includes resources in three subject areas • 1) Several professions allied to medicine • 2) Complementary medicine • 3) Palliative care • AMED covers articles from about 596 journals, many not indexed by other sources • http://www.bl.uk/collections/health/amed.html Evidence-based Chiropractic

  23. Evidence-based Chiropractic

  24. The Cochrane Library • Consists of eight evidence-based databases that deal with the effects of health care interventions • Provides regularly updated information and evidence to support health care decisions • Cochrane systematic reviews are full text • http://www.thecochranelibrary.org Evidence-based Chiropractic

  25. The Cochrane databases Evidence-based Chiropractic

  26. Evidence-based Chiropractic

  27. Multiple database searches • It is usually necessary to search more than one database in order to cover an EBC topic adequately • PubMed has limited coverage of chiropractic journals • However, many relevant articles are found in journals that are not indexed in the chiropractic specific databases (i.e., MANTIS and ICL) Evidence-based Chiropractic

  28. Obtaining copies of articles • Databases sometimes provide links to full-text articles • They typically only generate the article’s citation, including abstract • Copies of the full-text can be ordered directly from the publisher or obtained from a biomedical library Evidence-based Chiropractic

  29. Loansome Doc • Available through PubMed • Articles can be ordered within the PubMed website • Articles are delivered through a nearby DOCLINE library • Must first establish with a relationship with a DOCLINE library • http://www.nlm.nih.gov/loansomedoc/loansome_home.html Evidence-based Chiropractic
