11 Learning Objectives To familiarize students with the information retrieval process for evidence-based research To enable students to use synthesized/filtered/pre- appraised resources to answer research questions To enable students to use the 4S hierarchy of organization of evidence to plan search strategies

12 www.cebm.net “Evidence-based medicine is the integration of best research evidence with clinical expertise and patient values” Sackett DL, Rosenberg WMC, Gray JAM, Haynes RB, Richardson WS: Evidence based medicine: what it is and what it isn’t. BMJ 1996;312:71-2. Patient Concerns Clinical Expertise Best research evidence EBM What is EBM?

13 EBM Process – 5 Steps 1. ASK: Convert need for information into answerable question 2. ACQUIRE: Find best evidence to answer the question 3. APPRAISE: Critically appraise evidence for validity, impact, and applicability 4. APPLY: Integrate evidence with clinical expertise and patient values 5. ASSESS: Evaluate own effectiveness

14 “ Knowledge is the Enemy of Disease… but only if it is put into action.” Sir Muir Gray

15 Is All Evidence Created Equal? Small portion of medical literature is immediately useful to answer clinical questions Understanding “wedge or pyramid of evidence” is helpful in finding highest level of evidence High levels of evidence may not exist for all questions due to nature of medical problems and research limitations

16 As you move up the pyramid the amount of available literature decreases, but it increases in its relevance to the clinical setting.

17 Evidence Based Retrieval Find the answer that is supported by valid studies appropriate to the type of question and that is available in a timely manner Requires search terms plus best study design for question plus highest level of evidence

18 2. Best Study Design for Type of Question Type of QuestionStudy Design Therapy/preventionRandomized controlled trials DiagnosisProspective cohort, blind comparison to a gold standard PrognosisCohort, Case Control, Case Series Etiology/HarmCohort, Case Control, Case Series

19 Information Retrieval to conduct Research Comprehensive in scope and time  All levels of resources  Current and Retrospective  Background and Foreground Information 19

20 Background Questions Generally ask who, what, why, where or how about a single concept 20

21 Background Questions What foods naturally contain Vitamin D? What is the tolerable upper intake level (UL) for Vitamin D in healthy adults? What are the causes of Vitamin D deficiency? 21

22 Foreground Questions Usually compare two or more concepts – theories, drugs, treatments, tests, harms or benefits of two approaches 22

23 Foreground (Clinical) Question In post menopausal women with osteoporosis, is calcium plus vitamin D more effective than vitamin D alone in reducing the risk of hip fracture?

24 Answers to Foreground Questions Require precise information about complex issues Sources should provide current, original clinical research data  Start with evidence-based summaries and systematic reviews 24

25 Begin Search at Highest Level of Evidence - Critically Appraised Content Evidence Based Summaries UpToDate, Joanna Briggs Institute Clinical Key for Nursing Clinical Key for Nursing Cochrane Database of Systematic Reviews, Clinical Key for Nursing, Joanna Briggs Institute Clinical Key for Nursing, MEDLINE, CINAHL Complete, Science Direct SOURCE: Haynes, R. B. (2001). Of studies, syntheses, synopses, and systems: the “4S” evolution of services for finding current best evidence. Evidence-Based Medicine, 6 (2), 36-38.

26 New Tools Target High-Quality Studies Increase ease of accessing and understanding clinical information Preprocessed - practical resources that facilitate ready access to high-quality research Preappraised – tools that have undergone a filtering process to include only those studies that are regularly updated and of higher quality

27 Point-of-Care Resources Evidence based textbooks –Provide rapid access to concise information to clinicians at the point of care –Not a database of articles from books, journals, or guidelines –Original, current, summaries written by experts –Formal systems used to grade strength of recommendations and quality of evidence

28 Summaries UpToDate –Evidence based summaries of over 10,000 topics in over 22 specialties –8,500 Treatment Recommendations –GRADE System used to score recommendations and strength of evidence –Practice changing updates; Updated continuously –Drug database; Patient education materials –The Gold Standard of summaries

35 Databases – Clinical Key for Nursing 35

36 Databases – ClinicalKey for Nursing 36

37 Systematic Review Analyzes data from several primary studies to answer a specific clinical question Provides search strategies and resources used to locate studies Includes specific inclusion and exclusion criteria (results in less bias) Meta-Analysis (subclass) statistically summarizes results of several individual studies SOURCES: Cochrane Database of Systematic Reviews (Ovid Full Text), Clinical Key for Nursing, Joanna Briggs Institute

38 Cochrane Database of Systematic Reviews Part of the Cochrane Library (1996) 916 completed reviews, 1905 protocols Among the highest level of evidence upon which to base treatment decisions – the Gold Standard Includes Dx since 2008 Access through OVID 38

39 Appraisal Required by User

40 Primary (Original) Studies Articles that report results of original research investigations Conclusions supported by data and reproducible methodology Require time to acquire and appraise Good Sources: MEDLINE (Clinical Key or Ovid), CINAHL Complete, Science Direct

41 Databases – Ovid MEDLINE Premier biomedical database from the National Library of Medicine Provides journal articles in over 5,000 journals from 1946 to present in medicine, nursing, health care system, and allied health care practice, education, and research Useful to find articles on the relation of nutrition disorders to medical problems, e.g. “intake of fruits and vegetables to prevent cardiovascular diseases” 41

42 Use MEDLINE to locate Articles that report results of primary (original) studies Conclusions supported by data and reproducible methodology Hints:  In Ovid MEDLINE, search the Daily Update, and In-Process segments simultaneously with desired range of years  Search keywords along with subject headings

43 Databases - CINAHL Complete CINAHL stands for Cumulative Index to Nursing and Allied Health Literature Core research tool that contains full text of 1,400 journals and citations in more than 5,300 journals Check the box next to “suggest subject terms” and search CINAHL headings for best results, e.g., search “pediatric obesity” for “childhood obesity” View the brief tutorial to get started 43

44 Databases - CINAHL Complete 44

45 Databases – Science Direct Scientific database produced by Elsevier Provides journal articles from over 2,500 journals and chapters from almost 20,000 books in all life sciences disciplines Useful to find full text articles on nutrition and dietetics topics in scientific journals across multiple disciplines Contains full text of journals published by the American Academy of Nutrition and Dietetics 45

46 Consumer Health Resources Current, authoritative, peer-reviewed, and evidence- based resources written specifically for the layperson MEDLINEPlus – the National Institutes of Health’s web site for patients and families Joanna Briggs Database - provides full text consumer information sheets Clinical Key for Nursing - includes patient education handouts produced by Elsevier Access Medicine – provides comprehensive patient education materials in pdf format for adults and children 46

47 Databases – MEDLINEPlus National Institute’s of Health’s web site for patients and families Produced by the National Library of Medicine Contains current, reliable, well-written information summaries and videos about diseases, conditions, and wellness issues Widely used in major hospitals and medical centers 47

48 Take Home Points Focused research questions reveal your search terms Start your search at top of 4S hierarchy and work down Be aware of the filter, i.e., levels of evidence, speed of updating Look at more than one resource in the hierarchy. Findings may differ Assess validity (methodology) of the studies and applicability (how well they support) your research purpose

49 Tracking Down the Full Text If your database search does not provide a link to full text of a relevant article:  Print a list of the citations  Click on the Library e-Journals link on the Nutritional Sciences web page  Enter full title of the journal in the search box  Click on link to database that contains the full text 49

50 Life-Long Learning Selecting and searching online databases is challenging Information is ever changing Contact Sandra (email preferred) 50
