Outline • Background and Context: How did we get here? • Current Operations: What are we doing? • Future Directions: Where is this all going?
How did we get here? • Traditional Surveillance • Surveillance System Integration Project • “Syndromic” and multiple source surveillance • System Examples (data use complexity and challenges) • Summary of Data Analytic Issues • Information fusion concept
Biosurveillance Background • CDC Surveillance System Integration Project (1999) • Web-based public health information capabilities • 9-11-2001 • Syndromic Surveillance Conferences (Fall 2002) • DARPA BioAlirt Program (2002) • BioSense ‘rollout’ (Spring 2004) • National BioSurveillance Integration System (2004) • PL110-53 (2007) • Fusion Centers concept and BioPHusion Program (2007) • HSPD-21 (2007)

CDC Surveillance System Integration Project(1999) Gave rise to …. • Traditional disease reporting standards • Web-based display/screen standards • Use of aberration detection algorithms • Implementation process: • Public Health Information Network (PHIN) • National Health Information Network (NHIN)
Application Context Themes • Local vs Regional vs National focus • Interoperability / Transportability • Interdisciplinary science and technology • Culturalism • Language • Social networks • Case/Adverse Event definitions • Information exchange • Leadership
More Application Context Themes • Standards • Timeliness for response potential • Data access • Data quality factors • Signal detection thresholds • Testing Methodologies • System Evaluation • Emphasis on rapid cycle data updating
What is Needed for ‘Rapid Cycle’ Event Detection? • Modular software • Flexible for local, regional and/or national use. • Interoperable for various systems, platforms and data structures. • Produces graphics for interdisciplinary communication. • Amenable to assisting with signal definition. • Organized with potential for automation. • Acceptable operating characteristics. • Staff prepared to use it!
Bio-ALIRT Program(Defense Advanced Research Projects Agency) • “Bio-event Advanced Leading Indicator Recognition Technology” • Goal: Identify Nontraditional Data Sources and Develop Advanced Algorithms for Early Detection of Disease Outbreaks • Large Geographical Testbeds with Real Data Needed for Credible Research and Technical Development • Provide Increased-Alerts to Public Health • CDC participation (early 2003)

BioSense Vision • Provide local, state, and nationwide health situational awareness for suspect illness and cases of disease before, during, and after a health event • Help confirm or refute the existence of an event; monitor its size, location, and rate of spread Approach • Real-time delivery of healthcare data from hospitals, labs, ambulatory care settings, and other health data sources • Electronic “views,” analytics, and reports for national, state, and local public health, contributing healthcare organizations
Enables Public Health Access to Jurisdiction-Specific Data • Developing a nationwide capability for simultaneous access to biosurveillance data by all levels of public health • Able to provide cross-jurisdictional information during a public health threat event
BioSense ‘Rollout’ • Spring 2004 • Data: VA, DoD, Lab orders, OTC • Amplified need for … • Improved analytics • Visual data exploration methods • Statistical algorithms • Informed user guidance and support • Partnerships • More timely data
Main Factors Determining Analytical Priorities • Empirical nature of the data • Opportunistic, secondary use, spontaneously generated. • No sampling design • Multiple types and sources • Rare events of importance for detection (scarce data sets to ‘train on’) • ‘Dual Use’ for data system (traditional / syndromic) • New analytical models (rapid cycle surveillance) - experience is minimal.
Data Use-related Issues • Messaging/Data Challenges • Scalability and Capacity Challenges • Analysis and Visualization Challenges • Perception/concerns of privacy, confidentiality issues
National BioSurveillance Integration System(Dept of Homeland Security) • Planned and designed in 2004 • Involves multiple agencies and their respective domain information • Described in detail to House Subcommittee on Prevention of Nuclear and Biological Attack • May of 2006 • “Creating a Nation-wide, Integrated Bio-surveillance Network” • PL 110-53 assigns NBIC to DHS for full operational capacity by end of FY08.
NBIS Mission • Recognize biological events, including disease outbreaks and the use of biological agents, which present a risk to the nation, its infrastructure, and key assets • Collate, integrate, and analyze information from existing surveillance systems focused on human disease, food, agriculture, water, meteorology, and the environment, as well as other relevant threat information • Disseminate this all-source information to appropriate Federal departments and agencies and provide timely bio-situational awareness to support decision-making
Domain Detection Thresholds 72 hrs Agency A Detection Time 48 hrs Agency B Single domain threshold Agency C reached informs all members 24 hrs NBIS Detection Window Event Time NBIS Objectives Multi - domain cueing can reduce detection • Improved info sharing threshold below independent domain thresholds • Reduced detection time 7 Enhanced Surveillance
Summary of Data Analytic Issues • Modern biosurveillance is a ‘fast moving target’ • High volume across heterogeneity • Multiple outcomes of relevance within a record within a data source • Multiple data sources • Complex data setting • Hospitals, labs, emergency response etc. • Local, State and Federal public health • Diverse variety of potential data uses and types of queries • Maturity of system (related to available knowledge about the data)
Multiple Horizontal and Vertical Interdependent and Overlapping Activities • BioSense, BioWatch, BioShield • DHHS, DHS and DoD all receive directives to develop “bioIntelligence centers”. (2003) • DoD, DHS and DHHS Executive Officials challenged to provide “a unified system enabling the assessment of the health status of any community in the US when needed in real time”. (2005)
Pandemic and All-Hazards Preparedness Act • Signed into law in December 2006 • Public Law 109-417 • Further emphasis on public health preparedness including coordination
PL110-53: “Implementing Recommendations of the 9/11 Commission Act of 2007” • Authorized DHS to establish, enhance, and staff State, local, and regional fusion centers that comply with the guidelines established under section 210A(i). • Promotes information sharing in general • Promotes integration across subject matter domains • CDC used the same guidelines as a template to get our own ‘information house in order’ (as this law was under development in early 2007).
CDC BioPHusion Center • Inception discussed throughout 2007 • Office of Critical Information Integration and Exchange (FR Vol. 73, No. 96, p. 28483. May 16, 2008) • Designed to serve as an information exchange unit • Develop standard operating procedures for information exchange and communication • Provide ‘common operating picture’ and ‘situational awareness’ – actionable information
Homeland Security Presidential Directive - 21 • October 18, 2007 • 20+ Implementation Actions • Integration of all vertical levels of government and horizontal community components • Discipline of Disaster Health • CDC Biosurveillance Coordination Unit

BioPHusionMission Statement To provide a CDC wide resource that facilitates the exchange, integration, and visualization of relevant information from a variety of sources to enhance Agency and programmatic situational awareness for decision making and early event detection
BioPHusion: Purpose • Integration or ‘Fusion’ of public health information from existing CDC programs / external partners / other sources to: • Increase situation awareness • Improve early event detection • Support decision-making to protect the public’s health • Sharing timely and actionable information to public health programs and leaders at the national, state, local, tribal, and global levels

Director’s Critical Information Requirements BioPHusion must provide situation awareness of: Current and emerging public health threats in the U.S. Events that may become a public health threat to the U.S. Any threat to CDC staff, facilities, or resources worldwide. Any public health-related event of media interest.
