1. Research: Foundation of the Dietetics Profession Evidence Analysis Library and Evidence-Based Nutrition Practice Guidelines and Toolkits

2. ADA Definition/Description “ Evidence-Based Dietetics Practice is the use of systematically reviewed scientific evidence in making food and nutrition practice decisions by integrating best available evidence with professional expertise and client values to improve outcomes.” Approved by ADA HOD February 2006

3. Why Evidence-based Practice? To improve patient outcomes To improve safety, quality, efficiency To take advantage of “exploding” biomedical knowledge (thousands of new research studies appear every month)

4. Online Resource with the best available research on important dietetics topics in a practitioner-friendly format ADA Evidence Analysis Library www.adaevidencelibrary.com www.adaevidencelibrary.com

5. What are the steps in ADA’s Evidence Analysis Process? 1)Select Topic & Appoint Expert Working Group 2)Define Questions & Analytical Framework/ Determine Inclusion/Exclusion Criteria 3)Conduct Literature Review for each question 4)Analyze articles 5)Complete Evidence Summaries & Tables 6)Draft proposed Conclusion Statements 7)Reach Consensus on Conclusion Statements/Grades 8)PUBLISH to ONLINE LIBRARY (EAL)

18. Transition from Evidence to Evidence-Based Guideline Evidence Summaries/Conclusion Statements = what the evidence says Guideline = course of action for the practitioner based on the evidence

19. ADA’s Evidence-Based Guidelines Use best available evidence in making clinical decisions Use a systematic process for identifying, assessing, analyzing and synthesizing evidence as a basis for development Promote use of professional expertise where evidence is weak or lacking

20. Criteria and Classification for Guideline Development Criteria used to develop: Guideline Elements Model (GEM) AGREE Instrument National Guidelines Clearinghouse standards Classification: Recommendation ratings adapted from American Academy of Pediatrics

21. Transition from evidence to Guideline Formulation of: Recommendations: a series of guiding statements that propose a course of action for practitioners Clinical Algorithms: step-by-step flowchart for treatment of the specific disease/condition Introduction: scope, intent, methods, benefits/harms Appendices: food tables, etc. Glossary External review Publish on EAL

22. Features of Guideline Introduction Scope: disease/condition, objective, intended users, target population Statement of Intent Guideline Methods: process of guideline development, inclusion/exclusion criteria Implementation of Guideline Benefits and Potential Risks/Harms of Implementing

23. Features of Guideline Recommendations Written for the practitioner, as a course of action Describe “what” the practitioner should do and “why” it should be done Display rating using ADA scale  Strong, Fair, Weak, Consensus, Insufficient Evidence List potential risks/harms for implementing Provide a brief narrative illustrating the supporting evidence Provide rationale for the recommendation rating List any minority opinions Link to supporting evidence

35. E.g.Recommendation: Trans-fatty acids consumption should be as low as possible. A cardioprotective dietary pattern should contain less than 7% of calories from saturated fat and trans-fatty acids. Trans-fatty acids raise total cholesterol and LDL-C and may decrease HDL-C, thereby increasing the TC/HDL-C and LDL-C/HDL-C ratios. Increasing trans-fatty acid intake increases risk of CHD events. Disorders of Lipid Metabolism Evidence-Based Nutrition Practice Guideline

36. Statement Rating DefinitionImplication for Practice Strong A Strong recommendation means that the workgroup believes that the benefits of the recommended approach clearly exceed the harms (or that the harms clearly exceed the benefits in the case of a strong negative recommendation), and that the quality of the supporting evidence is excellent/good (grade I or II). In some clearly identified circumstances, strong recommendations may be made based on lesser evidence when high-quality evidence is impossible to obtain and the anticipated benefits strongly outweigh the harms. Practitioners should follow a Strong recommendation unless a clear and compelling rationale for an alternative approach is present. Fair A Fair recommendation means that the workgroup believes that the benefits exceed the harms (or that the harms clearly exceed the benefits in the case of a negative recommendation), but the quality of evidence is not as strong (grade II or III). In some clearly identified circumstances, recommendations may be made based on lesser evidence when high-quality evidence is impossible to obtain and the anticipated benefits outweigh the harms. Practitioners should generally follow a Fair recommendation but remain alert to new information and be sensitive to patient preferences. Weak A Weak recommendation means that the quality of evidence that exists is suspect or that well-done studies (grade I, II, or III) show little clear advantage to one approach versus another. Practitioners should be cautious in deciding whether to follow a recommendation classified as Weak, and should exercise judgment and be alert to emerging publications that report evidence. Patient preference should have a substantial influencing role. Consensus A Consensus recommendation means that Expert opinion (grade IV) supports the guideline recommendation even though the available scientific evidence did not present consistent results, or controlled trials were lacking. Practitioners should be flexible in deciding whether to follow a recommendation classified as Consensus, although they may set boundaries on alternatives. Patient preference should have a substantial influencing role. Insufficient Evidence An Insufficient Evidence recommendation means that there is both a lack of pertinent evidence (grade V) and/or an unclear balance between benefits and harms. Practitioners should feel little constraint in deciding whether to follow a recommendation labeled as Insufficient Evidence and should exercise judgment and be alert to emerging publications that report evidence that clarifies the balance of benefit versus harm. Patient preference should have a substantial influencing role.
