  1. Models of Information Summary, Synthesis, and Dissemination In Clinical Medicine Sources and Organization of Evidence-based Knowledge Principal Investigator: Elaine Martin, MSLS, MA Project Coordinator: Hathy Simpson, MPH Project Consultant: Roger Luckmann, MD, MPH

  2. Evolution of Medical Models of Information Dissemination • Information explosion • Increasing expectations of EBM practice • Studies documenting information needs • The Internet and advances in computer hardware

  3. Evolution of Medical Models of Information Dissemination • Improving computer searching strategies and results displays • Development of methodology for EBM critiques and systematic reviews • Market forces driving rapid development of many new online resources: full text books and journals, collections of databases, new original online content creatively organized

  4. Information Needs and Resources in Medicine and Public Health • Need for answers to problem-specific questions arising frequently in daily practice, not answered by common knowledge/guideline. • Med: Most common need usually related to individual patients • PH: May be much less common need, more often related to a population, sometimes to individual clients

  5. Information Needs and Resources in Medicine and Public Health • Need for best information to develop/revise policies, programs, and guidelines. • Med: Common need only for select group of practitioners • PH: May be most common need

  6. Information Needs and Resources in Medicine and Public Health • Type of information needed • Med: Very large databases of interventional studies, observational studies, guidelines, accumulated clinical and basic science knowledge relevant to both routine questions and policy/guideline development • PH: Many fewer community interventional studies, similar needs for observational studies and guidelines, also evaluation studies, accumulated public health knowledge, epidemiologic data, policies and procedures

  7. Models of Summary, Synthesis and Dissemination ofClinical Medical Evidence • Reports of Original Research • Summaries, Critiques and Commentaries on Individual Original Research Studies(and sometimes systematic reviews and meta-analyses) • Systematic Reviews and Meta-analyses (focus on a topic and often provide a guideline for practice) • Comprehensive Knowledge Bases

  8. Reports of Original Research Formats: • Hardcopy of journals • Online journals • Collections of online journals • Databases of study titles, abstracts, and references (Medline, other relevant databases)

  9. Reports of Original Research Quality: • Varies widely • Editors and reviewers responsible • Quality filters for assisting in searching databases Updating: • Regular and frequent related to schedules of journal publication

  10. Reports of Original Research Pushing • Regular emails of titles and abstracts • Selected topics • Wide range of delivery services • Single journal, multiple journals

  11. Reports of Original Research Medical Examples: • Journal Websites • OVID Medline • PubMed • Web of Science • SGIM abstract delivery

  12. Reports of Original Research Public Health Examples: • MMWR and MMWR Website • AJPH email services • SafetyLit • Healthy People 2010 Information Access project (Medline Filters)

  13. Reports of Original Research Possible Applications in Public Health: • Facilitated access to collections of online public health related journals • Service to push titles and abstracts of relevant articles to practitioners • Filters for searching existing databases for best information • Search engines to search multiple databases simultaneously

  14. Reports of Original Research Issues: • Limitations of quality filters • Information overload from searches of large databases • Problems in customizing content of pushed information and avoiding information overload

  15. Summaries, Critiques and Commentaries Format: • Newsletters and journals in hardcopy and online • Searchable electronic databases (CD-ROM and online)

  16. Summaries, Critiques and Commentaries Quality: • Dependent on qualifications and skills of editors/commentators • Related to methodology for summarization and critique

  17. Summaries, Critiques and Commentaries Updating: • Periodically as new studies come out • Driven by publication of new material • Lag time due to production of summaries and commentaries Pushing: • Regular mailing of hardcopies

  18. Summaries, Critiques and Commentaries Medical Examples: • Journal Watch • ACP Journal Club • Annals of Internal Medicine • Faculty of 1000 Public health examples: • Journal Watch Infectious Diseases
