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

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

13. Information Retrieval for Evidence Based Health Care Using research findings versus conducting research Retrieving and evaluating information that has direct application to specific patient care problems Selecting resources that are current, valid and available at point-of-care Developing search strategies that are feasible within time constraints of clinical practice

14. 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?

15. 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

16. Integration of Clinical Research into Patient Care Process

17. Clinical Questions Four common types:  Therapy/prevention  Diagnosis  Etiology  Prognosis

18. Answerable Questions Select Questions That:  Are most important to the patient’s well being  Fill gaps in your clinical knowledge  Are feasible to answer in the time available

19. Information Retrieval to Answer Clinical Questions Requires New Skills Clinical question formulation Search and retrieval of best evidence Critical appraisal of study methods

20. 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

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

22. 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

23. Therapy/Prevention Question 1. What is the best available evidence regarding the effectiveness of intake of fruits and vegetables to prevent cardiovascular diseases? 2. Find the answer that is supported by valid studies, appropriate to the type of question, and that is available in a timely manner.

24. PICO Model P -Patient or population I - Intervention C -Comparison Intervention O - Outcome

25. Clinical Question – Therapy/Intervention P -Patient or population In patients free of diagnosed cardiovascular disease, I - Intervention is increased intake of fruits and vegetables (2 or more servings per day) C -Comparison Intervention compared to fewer servings per day (1 or less) O - Outcome effective in preventing primary cardiovascular disease?

26. 1. Possible Search Terms cardiovascular disease, primary, fruits and vegetables, prevention

27. 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

29. 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

30. 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

31. 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

33. UTD – fast, current, peer reviewed

36. UTD – simple search, quick answers

37. Joanna Briggs Institute (JBI) an international, not-for-profit research organization at the University of Adelaide collaborates internationally with over 70 entities to promote synthesis and transfer of evidence contributes to improving health care outcomes by supporting evidence-based practice 37

38. JBI Database Evidence Summaries – literature reviews that summarize existing literature on common health care problems Evidence-Based Recommended Practices – procedures that recommend practice on clinical topics Best Practice Information Sheets – guidelines produced for practicing health care professionals Systematic Reviews – comprehensive reviews of international research literature Consumer Information Sheets – summaries designed for patients, clients, and care providers Updated weekly, access through Ovid 38

39. Databases – ClinicalKey for Nursing All in one resource provides access to e-Journals, e- Books, MEDLINE, images, videos, and more Unique features include full text “disease overviews” with links to related topics and resources Smart Search interface includes:  Autosuggest search terms to quickly display concepts, procedures, and drugs related to your topic  The most current, clinically relevant answers at the top of your search Full text monographs of all FDA approved drugs and patient education handouts 39

42. 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

43. 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 43

45. Appraisal Required by User

46. 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

47. When to search for original studies If the other “S’s” don’t provide the answer, search for original studies “Do it yourself” appraisal territory You must appraise quality of the study or find analysis in evidence based summary Quality of the journal does not always guarantee quality of individual studies Limit to “Clinical Queries” in Ovid MEDLINE and CINAHL Complete

48. Take Home Points Focused clinical question (PICO) reveals 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 Apply in clinical settings and continually assess your progress
