Enhancing Evidence-based Information Access to Inform Public Health Practice

This project aims to improve access to evidence-based information for public health practitioners by identifying their information needs and developing integrative models for accessing information. The study findings will inform the development of resources and strategies to overcome barriers to information access.

  1. Enhancing Evidence-based Information Access to Inform Public Health Practice Modeling Public Health Information Needs and Accessing Requirements December 14, 2005 conducted by: University of Massachusetts Medical School Library funded by: Center for Disease Control and Prevention Association of Teachers of Preventive Medicine Project TS-0734

  2. Project Staff & Resources Principal Investigator: • Elaine Martin, DA Project Coordinator: • E. Hatheway Simpson, MPH Consultants: • Nancy La Pelle, PhD • Roger Luckmann, MD Evidence-Based Practice for Public Health Project Website: http://library.umassmed.edu/ebpph

  3. Project Background & Purpose Qualitative Study Findings Part 1: Information Needs Continuum Model Existing Public Health (PH) Information Resource Examples Qualitative Study Findings Part 2:Information Accessing Requirements Not Fully Addressed Hypothetical Integrative Model Based on Findings Outline

  4. Project Background • Evidence can be applied to solve public health problems if readily accessible • Many barriers identified by other researchers including limited: • Encouragement to seek it • Awareness of what is available • Access to computers/internet • Accessing skills • Time to search • Ability to appraise credibility & availability of systematic reviews • Access to required information beyond biomedical field

  5. Project Purpose • Build on and integrate findings from related studies & review of existing resources • Use qualitative method to identify information needs to inform PH practices • Use findings to inform development of integrative models of PH information and accessing needs

  6. EBPPH Research Process Step 1 - Identify existing resources and features Step 3 - Focus group with BCDC participants Step 2 - Interview BCDC participants Step 5 - Develop hypothetical model system Step 4 - Interview CHP participants Step 6 - Focus group with CHP participants Step 7 - Revise hypothetical model

  7. Qualitative Study Detail Sample: • Two groups: Communicable Disease Control & Community Health Promotion • 19 State level PH professionals with strongest info accessing needs Data Collection & Analysis: • Taped/transcribed key informant interviews • Taped/transcribed follow-up focus groups • Thematic analysis of all data; comparison across groups • Model development & review with informants

  8. Focus of Individual Interviews • Type of work tasks performed requiring access to critical external information? • Current used and preferred info sources (online and offline)? • Preferred format for research reports (abstracts, full text, reviews/commentaries)? • Current barriers to information access? • Desired enhancements for access?

  9. Individual Interview Findings Related to Context • All DPH staff have PCs, access to internet • Large sophisticated DPH website • Multiple DPH sites and more than one library site • Urgency of information need differs widely • Electronic information access differs widely

  10. Findings: Information Needs Continuum Model Emerged Formal Research Support for Information Minimum Maximum Published research reports and meta-analyses Emerging practices • Emerging health • risks and preventive • behaviors Evaluated practices • Evidence-based • guidelines • Well-known disease • reference info Examples: SARS, new STD, TB, Effective Immunization health risks venues CVD interventions Clinical standards Typical Access Mechanisms: Automatic Colleagues, Web Journal Websites notification conferences, sites search listserves engines

  11. Current PH Information Resource Types Reviewed in Focus Groups Providing electronic access to: • Research Reports: • Simple or preformulated searches of research report collections • Alerts & archiving • Summaries/commentaries/critiques • Systematic reviews and other evidence-based resources • Comprehensive knowledge sources

  19. Information Accessing or Formatting Features Website Examples of Specific Features Reviewed with Informants Keywords for searching published literature for articles of interest PubMed Pre-formulated search or screening filters • Partners in Information Access for the PH Workforce • PubMed Clinical Queries Automatic notification (alert systems and topical listservs) • SafetyLit • AJPH Online Subscriber Help & Services • TB-UpDate from the CDC Abstracts, summaries and expert commentaries • Journal Watch • Evidence-Based HealthCare and PH Systematic reviews Cochrane Systematic Reviews Evidence-based guidelines Guide to Community Preventive Services Comprehensive knowledge collection • UpToDate • CDC website Within article indexing UpToDate Archiving of information sought SafetyLit

  20. Focus Group Findings Regarding Accessing Needs • One portal searching access • Access to consistent information for all diseases/populations and from diverse disciplines of interest to PH professionals beyond PubMed scope • Better access to relevant and credible “grey literature” as well as systematic reviews and full text

  21. Focus Group Findings Regarding Accessing Needs • Credibility of information systematically reviewed • Training on how to access information electronically • Mediated searching=article retrieval services

  22. PH Information Access Model Newly published information in diverse disciplines of interest User-selected filters & pre- formulated search criteria Review System PH Evidence-Based Information Access Website • Journal articles • Systematic reviews • Practice Guidelines • Best Practices • Relevant “grey literature” Credible indexed info Automatic notification of newly available requested filtered information Customized user database of accessed information
