  7. Clinical PH Information Interchange – Research Questions • Clinical (patient) information to support chronic disease interventions in communities: what is the minimum data set? • Situational awareness data exchange – how to do in a focused, timely, comprehensive way? • PH clinical data (e.g. immunization, disease status, relevant community information) to electronic health record? • Timely approaches to people and directory type information interchange? • Research findings – how to extract from the literature and present to practitioners? • Utilization of community health information for decision support for individual patients? Center for Public Health Informatics University of Washington

  8. CPHI Key Research Areas • Knowledge in Practice 1.Managing information resources and data for PH practice 2.Business process analysis and workflow characterization • Surveillance Data for PH practice • Collection and Analysis • Geospatial Presentation

  9. Knowledge in Practice: The Challenge • Neither the creation nor the distribution of information resources* upon which public health practitioners depend is managed or presented in any systematic or comprehensive way at the present time *data of all types, guidelines, research findings, maps, policies, laws, evaluation metrics, teaching materials, etc. Center for Public Health Informatics University of Washington

  10. Approach Research workflow and information needs of public health practitioners to support evidence-based practice Develop and optimize a knowledge management system to support iterative refinement of a set of retrieval and information management tools for public health practitioners Center for Public Health Informatics University of Washington

  11. Information Needs of Public Health Practitioners: Observations • Few formal studies of information needs, information-seeking behavior or workflow of PH professionals • Rapidly expanding volume of data and information • Major barriers: time, resource reliability; discerning credibility of information • People are a critical source of information in public health • Silos of surveillance information – lack currency and context • Lack of linkages between individual patient information and public health information systems • Revere D, Turner A, Madhavan A, Rambo N, Bugni PF, Kimball AM, Fuller SS. Understanding the information needs of public health practitioners: A literature review to inform design of an interactive digital knowledge management system. J Biomed. Informatics 2007. Special Issue on Public Health Informatics. Center for Public Health Informatics University of Washington

  12. Information Needs of Public Health Practitioners Resources used influenced by job function, disciplines & training Want resources that are easy to access & use, up-to-date, free, pre-digested & stable, focused One size/approach does not fit all; personal customization is highly desired Revere D, Turner A, Madhavan A, Rambo N, Bugni PF, Kimball AM, Fuller SS. Understanding the information needs of public health practitioners: A literature review to inform design of an interactive digital knowledge management system. J Biomed. Informatics 2007. Special Issue on Public Health Informatics. Center for Public Health Informatics University of Washington

  13. Information Needs of Public Health Practitioners: Resource Types • Information from areas beyond biomedical domains: e.g. social, legal, policy • Systematic reviews & summary information • Government reports (grey literature) & conference proceedings • Evidence-based resources – e.g. full-text research articles; synthesized reviews of clinical topics • Data from community-based and clinical systems with geographic mapping and analysis capability Center for Public Health Informatics University of Washington

  14. Why a Content Management System? CMSs streamline the process of creating, managing & delivering content, & put processes in place to manage & control information as it is moved & changed • Publishing • Web delivery • Portal delivery • Content distribution & syndication • Streaming • Real-time content • Content intelligence • Collaboration services • Transformation • Renditions • Process automation • Library services • Repository services Manage Deliver Content Management Solution Create / Capture Archive / Retire • Authoring • Importing • Aggregation • Imaging • Records management • Final form storage Review / Approve Center for Public Health Informatics University of Washington

  15. Rapid Prototyping: Iterative Refinement Process Center for Public Health Informatics University of Washington

  16. Prototyping the Interface • Toolkits • Locally customizable, role-based resources views • Advanced retrieval tools Beta Version 3.0 http://myph.org/ Center for Public Health Informatics University of Washington

  18. Usage of myPH Prototype: Data summary, 03/05/2007Promotion began ramp-up - Feb 2007 http://myph.org/webalizer Center for Public Health Informatics University of Washington

  19. Core Workflow Problem • The information processes and workflow of public health practice are not well characterized, making it difficult to build public health information systems that efficiently support practice.

  20. Workflow Analysis Research • Faculty from the UW-CPHI are participating in requirements definition projects: • Kitsap County Health District - chronic disease prevention and control (J. Baseman, A. Turner) • Spokane County Health District - public health preparedness (B. Karras) • Significance to PH Practice: improved efficiency, cost savings, improved disease surveillance, and improvements to the health of communities

  21. Biosurveillance Research • Value of data • Decision support for biosurveillance: Utility functions for identifying and evaluating a minimum data set (J. Doctor, J. Baseman, B. Lober) • Notifiable condition reporting • Electronic forms to support notifiable condition reporting in a health information exchange infrastructure (B. Lober, J. Baseman, B. Karras) • Future: Bayesian networks for case identification • Algorithms for probabilistic reporting criteria • Geospatial mapping of disease incidence

  22. Uncertainties about Biosurveillance Data • Timeliness • Organizational processes • Data entry, system architectures • Network traffic delays • Integrity • Accuracy, Completeness • Depends on quality control • Relevance • Depend on purpose of data analysis • Outbreak detection, situational awareness, program monitoring & evaluation, community assessment • Multi-attribute Utility Theory - Utilizing to determine trade-offs

  23. Relevance • Time tradeoff • Children exposed to a child w/. suspected measles. Low prior probability  confirmation needed. Time tradeoff w/ efficacy of vaccination. Utility of a lab result in N hours? • Subjects/Sampling/Instrument • PH professionals practicing at County PH offices • Email request sent to County PH Officers in WA • Interactive Web Survey - Tradeoff questions, rating scales and demographic questions

  24. Notifiable Conditions Survey

  25. Utility as a function of lab delay on time to act - measles outbreak Data elements have tractable utility representations, and utility tradeoffs. PH professionals place nonlinear value on time-to-act, preferences

  26. Electronic Notifiable Condition Reporting • Electronic forms using Xforms technology (XML) • Form instance and data instance • Demonstration showcased: • Provider engagement • Efficiency through form pre-population • Efficiency through electronic transmission • Inherent auditing, recording workflow Center for Public Health Informatics University of Washington

  27. Incidence: ICD-0: C34.0-C34.9, excluding histology codes 9140, 9590-9989 Mortality: ICD-9 (1990-1998): 162.2-162.9,  ICD-10 (1999- ): C34 Lung Cancer in Washington State Age Adjusted rates Tables Center for Public Health Informatics University of Washington

  28. Conclusion • Integrated PH decision support systems are in their infancy in the U.S. • We can learn from lessons of clinical decision support system design and deployment • It is critical that we figure out how to optimize timely data exchange of critical information between clinical and public health information systems • Much more work is needed to understand information needs and practice in order to optimize the decision support environment for public health practitioners Centerfor Publ ic Health Informatics University of Washington
