2. Purpose Evaluate Internet sources Rank scientific information by level of evidence Cite Internet sources appropriately

3. Evaluate Internet sources

4. Types of Internet Sources The Internet is a pathway to depositories of sources. The Internet allows retrieval of a primary source at another location, e.g., journal (periodical) that is accessed online. The Internet itself holds information that could be used as a source (usually considered secondary or tertiary source), e.g., Web pages.

5. Types of Information Sources Primary information source Must be the original scientific evidence Must conform to acceptable scientific standards for conducting and reporting such research Must pass peer review American Public Health Association: Chiropractic Health Care; Washington DC: What are authoritative sources for scientific evidence-based and peer-reviewed information? http://www.apha-chc.org/vaccinfo/authoritative_sources.htm

6. Types of Information Sources Secondary information source Integrates scientific evidence from a number of original research studies (review article) Conforms to scientifically acceptable methodological standards for gathering, synthesizing, and reporting the available evidence Should be peer-reviewed American Public Health Association: Chiropractic Health Care; Washington DC: What are authoritative sources for scientific evidence-based and peer-reviewed information? http://www.apha-chc.org/vaccinfo/authoritative_sources.htm

7. Types of Information Sources Tertiary information source Information drawn from primary and secondary articles that are peer reviewed: e.g., textbook (may or may not be peer reviewed) Summary of the information available on a topic, selected in an unbiased manner American Public Health Association: Chiropractic Health Care; Washington DC: What are authoritative sources for scientific evidence-based and peer-reviewed information? http://www.apha-chc.org/vaccinfo/authoritative_sources.htm

9. Evaluating a Web site Accuracy Authority Objectivity Currency or timeliness

10. Rank scientific information by level of evidence

11. What is EBM*? EBP marks a paradigm shift from traditional decision making in medicine Intuition Unsystematic clinical experience Pathophysiological rationale *EBM = evidence-based medicine; EBP = evidence-based practice

12. What is EBM? Common definition: The conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients Integrating clinical expertise with the best available external evidence from systematic research Thoughtful and compassionate use of patient values -Sackett, BMJ 1996;312, 71-2

13. The Evidence Hierarchy From: http://www.dartmouth.edu/~biomed/services.htmld/EBP_docs/pyramid-loaded.pdf

14. What Are Systematic Reviews? Focus on a clinical topic and answer a specific question Extensive literature search for all studies with sound methodology Results summarized to answer the question For example: Cochrane Database of Systematic Reviews --Connie Schardt, Health Science Library, Duke University

15. What Is a Meta-Analysis? Takes systematic reviews a step further by pooling data from individual studies as if it was one large study Synthesizes many studies Uses statistical methods to combine data from two or more studies Connie Schardt, Health Science Library, Duke University

16. What Is a Wiki? Wiki = piece of server software that allows users to freely create and edit Web page content using any Web browser Wikipedia and other wikis Most are not peer-reviewed. None publish original research. Anyone can contribute to or alter a page. At best, most wikis are secondary or tertiary sources—not primary.

17. Cite Internet sources appropriately

18. Why Use References? Documentation Acknowledgment Link to additional information or resources

19. Citing Web Sources Web site content may change frequently. Web site may disappear. Print and online versions of an article or publication may differ.

20. Citing Web Sources Print a copy Check links repeatedly throughout publication process Note date accessed Include DOI/PMID* if journal requires *DOI = digital object identifier; PMID = PubMed unique identifier

22. Minimum acceptable data: Author (organization) Title Name of Web site URL Date accessed A URL alone is not sufficient! Citing a Web site

23. Let’s Try Searching for Information! Some suggested databases to locate EBM information are: MEDLINE (using EBM filters) “Clinical Queries” National Guidelines Clearinghouse (NGC) Turning Research Into Practice (TRIP) The Cochrane Library
