Hanrahan PhD MS Principal Investigator Wisconsin Division of Public Health Population Health Sciences 802 Madison, WI. November 13, 2002Objectives: Objectives Understand Informatics Understand Wisconsin’s Implementation of NEDSS & HAN Know NEDSS Design Elements Opportunity to envision What is Informatics?: What is Informatics? The Application, Management and Use of Information and Computer Science and Technology to a field (practice), research, and learningLevels of Biomedical Informatics: Levels of Biomedical Informatics Bioinformatics - Molecular, Cellular (e.g. gene sequences) Imaging Informatics - Tissues, Organs (e.g. radiology) Clinical Informatics - Patients (e.g. Computerized Physician Order Entry) Public Health Informatics - Populations (e.g. Disease Surveillance Systems)Public Health Informatics: Public Health Informatics Systematic Application of Information and Computer Science and Technology to Public Health Practice, Research, and LearningPublic Health Informatics: Public Health Informatics Knowledge Application from: Information Science, Computer Science Management, organizational theory, Psychology, Communications, Political Science, Law Public Health: e.g. Epidemiology, Microbiology, Toxicology, Biostatistics Public Health Informatics - Foundations: Public Health Informatics - Foundations Information Science - Analysis of Structure, Properties, Organization, Storage & Retrieval of Information: DB Design & Architecture, Library Science, Project Management, Change Management, Business Process Reengineering Public Health Informatics - Foundations: Public Health Informatics - Foundations Computer Science - Automatic Data Processing Machines, Hardware and Software Design, Algorithm Development, Computational Complexity, Networking & Telecommunications, Pattern Recognition, Artificial IntelligenceSlide9: Public Health Informatics: Automation vs Reengineering Replace Paper with PC Based Surveillance Data Entry Systems vs Eliminate Surveillance Data Entry - Poll Information from Existing Clinical Information Systems & Electronically Transmit, Real Time Analysis & Automated Intervention Slide10: Public Health Informatics Principles - Apply Science and Technology to: Promote Population Health Prevent Disease and Injury Prevent at all vulnerable points in causal pathways Governmental Context - with Private Sector Partnerships Slide11: Our Implementation of NEDSS (and HAN): ‘The Wisconsin Idea’ IT Governance - Stakeholders DHFS-DPH - Public Health UW-WISCNET - Network UW-DoIT - Internet, Learning Technology State Laboratory of Hygiene Local Public Health Departments Hospitals, Clinics, ERs, Labs, SecuritySlide12: WISCONSIN HEALTH ALERT NETWORK GOALS: Improve Internet (T1) Connectivity - All Local Health Departments Create Distance Learning Infrastructure Create Web / Multi-platform Alert Messaging System Assess Organizational Capacity Slide13: What is the National Electronic Disease Surveillance System (NEDSS)? The Web Enabled Public Health System National Data Standards / Architecture for Public Health Eliminate Program / Data Silos Add in Systems (Modules) Secure Slide14: HAN-Basic Infrastructure NEDSS- Epi-X Capabilities Public Health Response Bioterrorism - All Foci Emerging Infections All Other Health Threats Assuring Public Health PREPAREDNESSLimitations of Current Public Health Surveillance Systems: Limitations of Current Public Health Surveillance Systems Multiplicity of categorical systems Data incomplete, not timely Burden on respondents in health care sector increasingly unacceptable Systems do not utilize state of the art information technology NEDSS, broadly: NEDSS, broadly Capture and analyze data in real time, using data that are already electronic Organize surveillance by relevant data sources, not diseases Do standards-based development in a defined architecture, using commercial products Integrate public health and health care data, as appropriate Emphasize adoption and implementation of standards Gartner Group – “…right approach to a tough, classic problem in application integration.” How can NEDSS meet Public Health Surveillance Needs?: How can NEDSS meet Public Health Surveillance Needs? NEDSS uses actual or de facto national standards for architecture; NOT specific to infectious disease Substantial emphasis on need for broad functionality at second NEDSS stakeholders’ meeting, April 2001 Current discussions with vital registrars, NCHS to harmonize new birth and death records re-engineering with NEDSS standards FY2001 intra-mural $’s to support NEDSS pilot projects beyond infectious diseases blood lead levels: NCEH, NIOSH; GIS and toxic substances data: ATSDR, NCEH, EPO SENSOR RFP; Environmental TrackingSlide18: NEDSS - 8 Design Elements Web data entry / management Process HL7 / XML Integrated data repository data exchange (integration broker) transportable business logic data reporting / visualization LDAP directory of public health personnel security system / policies Slide19: Implement an integrated data repository able to be patient centered, non-categorical support “thick” client and web applications (ODBC, JDBC and ANSI SQL)Slide20: Implement a security system and appropriate security policies (Internet-based, with a firewall and certificates or tokens) Security Slide21: Conduct and support web browser-based data entry and data management. Internet presentable, but not necessary Multi-tiered including an application server to run web “forms” from others State Health Department Local Health Department Or Clinical Site SecuritySlide22: Accept, route and process electronic HL7 messages containing laboratory and clinical content (LOINC, SNOMED).
