  • Library is housed in Aunt Hattie’s BarnMost resources are online
  • The library website is your gateway to our online resourcesLibrary 101 is a tutorial on information literacy and using our libraryShould already be enrolled and will stay enrolled so you can consult at any timeExcellent review
  • We want to talk mainly today about searching for evidence – search strategies to use in evidence based practiceWe wrote a chapter in a forthcoming book on this topic for nurse midwives and this presentation follows that chapter outlineThis is a word cloud of the chapter
  • Most commonly cited definition from seminal article in BMJ
  • EBP cycle – we come in mostly in 3 and 4
  • Evidence Hierarchy – best evidence on topSystematic Reviews – an overview of all primary studies on a topic; “interrogating the literature”Meta-analyses – combine statistical data from individual studies and recalculateCritical appraisal – summaries to answer specific clinical questions – often found in point of care toolsRCTs – patients/subjects assigned to either receive treatment or serve as a control; other variables do not come into playCohort and case-controlled studies – compare two groups (one with condition or intervention, one without); cohort follows the groups over time, case control looks at historiesConsensus statements – guidelines from respected authorities (professional organizations)Anecdotal information – least reliable since it cannot be verified, but uses experience
  • Field – individual piece of information within a record
  • These are the ones we have – there are others
  • Zach will demo RefWorks
  • Most important resource…Once you pick your topic, talk to us before starting lit reviewWe can discuss subject headings and keywords, resources; brainstorm search strategies, etc.
  • Using the Library / Searching for the Evidence

    1. 1. Using the Library DNP Bound Frontier Nursing University
    2. 2. Alice Whitman Memorial Library
    3. 3. Alice Whitman Memorial Library Library Home Page Library 101 in ANGEL
    4. 4. Evidence Based PracticeSEARCHING FOR THE EVIDENCEGebb, B.A., Young, Z., & Anderson, B.A. (2012). Evaluating and using the evidence. In B.A. Anderson & S. Stone (Eds.), Best practices in midwifery: Using the evidence to implement change. New York: Springer Publishing.
    5. 5. Evidence Based Practice• What is EBP? – Most commonly cited definition is “the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients.” – Sackett, D.L., Rosenberg, W.M.C., Gray, J.A.M., Haynes, R.B., & Richardson, W.S. (1996, January 13). Evidence-based medicine: what it is and what it isn’t. BMJ, 312(71). Retrieved from http://www.bmj.com/content/312/7023/71.full
    6. 6. Evidence Based Practice The EBP Cycle• Identifying a clinical problem• Formulating a focused, answerable question• Locating relevant and appropriate resources• Searching for information• Critically appraising the information• Implementation in clinical practice
    7. 7. What is Evidence? Systematic Hierarchy of Research EvidenceHierarchy of Research Evidence Reviews Meta-Analyses Critical Appraisal Randomized Controlled Trials Cohort and case-controlled studies Consensus Statements Anecdotal Information
    8. 8. Search Strategy• Form a clinical question – Must be focused and answerable NOT What are therapies for depression? INSTEAD Does exercise reduce depressive symptoms in women?
    9. 9. Form a Clinical QuestionPICO framework: P – patient/problem I – intervention C – comparison O – outcome
    10. 10. Form a Clinical QuestionDoes exercise reduce depressive symptoms inwomen? P – women with depression (age group?) I – exercise (how strenuous? how often?) C – medication O – symptom reduction, quality of life
    11. 11. Boolean Operators AND – both terms must be present (will narrow a search) OR – either term is present (will broaden a search) NOT – only first term is present (will exclude terms)
    12. 12. Boolean Operators• exercise AND depression – will retrieve articles with both words• zoloft OR sertraline – will retrieve articles with either word• exercise NOT running – will retrieve articles with exercise and exclude those with running
    13. 13. Field Searching
    14. 14. Subject Headings• Specific words or phrases selected from a controlled vocabulary that describe a work – MEDLINE = MeSH – CINAHL = CINAHL Headings
    15. 15. Limiters• Parameters for your search – MEDLINE limiters include: • Age group • Publication type • Language • Dates
    16. 16. Research Filters• Research filters are pre-designed search strategies• Clinical Queries – PubMed page: http://www.ncbi.nlm.nih.gov/pubmed/clinical – Limiter in MEDLINE (EBSCOhost) – ((clinical[Title/Abstract] AND trial[Title/Abstract]) OR clinical trials[MeSH Terms] OR clinical trial[Publication Type] OR random*[Title/Abstract] OR random allocation[MeSH Terms] OR therapeutic use[MeSH Subheading])
    17. 17. Where is the Evidence?• Traditional bibliographic databases• Meta-search engines• Point of Care resources
    18. 18. Bibliographic Databases• MEDLINE – via EBSCOhost – via PubMed• CINAHL• Cochrane Library• Joanna Briggs Institute – via ProQuest
    19. 19. Meta-search Engines• SUMsearch – http://sumsearch.org• TRIP database – http://www.tripdatabase.org
    20. 20. Point of Care Tools• DynaMed• Essential Evidence Plus• Natural Standard• Lexicomp
    21. 21. Additional Tools• Search Alerts – MyNCBI – MyEBSCOhost – RSS Feeds
    22. 22. Citation Management
    23. 23. Finally…• Don’t forget about librarians as a resource!• Call us before starting your literature review!
