3 Pew Environmental Health Commission Report “America’s Environmental Health Gap: Why the Country Needs a Nationwide Health Tracking Network”Highlights lack of public health infrastructure and leadership to track chronic diseases and environmental exposures
4 Pew RecommendationsBuild State and Local Capacity for Defending Against Environmental Health ThreatsCreate a nationwide environmental health tracking network
5 Pew Environmental Health Commission: Goals of Tracking Network Identify populations at risk and respond to outbreaks, clusters and emerging threats;Establish the relationships between environmental hazards and disease;Guide intervention and prevention strategies, including lifestyle improvements;
6 Pew Environmental Health Commission: Goals of Tracking Network (cont.) Identify, reduce and prevent harmful environmental risks;Improve the public health basis for policymaking;Enable the public’s right to know about health and the environment; andTrack progress towards achieving a healthier nation and environment.

9 Tracking Frameworks: Questions EnviroHazardHealthOutcomeBasic Distribution Questions: Right-to-Know FunctionWhat hazards are we exposed to?In what amount or concentration?Are exposures changing?How does my (community) exposure compare to others?Did the environmental policy prevent or control the hazard?What is the rate of disease X in my community?Is this high or low?Is the disease rate changing?How does my (community) disease rate compare to others?Did the health policy prevent disease?Linkage Questions: Hypothesis FormulationDoes a change (+/-) in a health outcome correspond in time & place to changes in hazards?Does a change in hazards correspond in time & place to changes in health outcomes?Hypothesis Testing Investigation: Controlled StudyIs the observed association in time and place valid? Can it be replicated? Note basic distribution data can inform where to look to perform case-control study.
10 Tracking Frameworks: Value of Linkage HazardOutcomeNew Cases & Prevalence / TimeAmount & Location /TimeValue of linking information increases with (1) time and (2) changes in hazard loading and outcome rates. Collecting hazard and outcome information over time provides better information about population health thus addressing social, scientific and policy questions.
11 SB 702Senate Bill 702 (Escutia) signed by Gray Davis in Oct mandates that CDHS lay the groundwork to establishing a Environmental Health Tracking NetworkCollaborative project with UC, and Cal/EPA
12 Bill MandatesCreation of an expert working group to develop possible approaches to establishing tracking network (including estimated costs)Prepare report to DHS, Cal/EPA, and legislative committeesDevelop health and environmental measurements for tracking
13 CDC National Environmental Public Health Tracking Cooperative Agreement Funded to CA Dept. of Health Services, in partnership with Office of Environmental Health Hazard Assessment, Cal/EPAThree years, $791,000 annually

15 CDC Agreement GoalsBegin process of implementing a standards-based health and environment tracking networkIncrease state, local, and national capacity for environmental health trackingImprove collaborations between State’s public health and environmental agenciesImprove dissemination of environmental health data to policy decision-makers and other stakeholders
16 CDC Agreement Objectives (6) Involve stakeholders by convening a Planning Consortium for program planning, implementation, and evaluation.Identify and prioritize state and local needs to develop a tracking networkNeeds assessmentsFeasibility of using indicators for surveillancePrioritizing informational, hardware, software needs
17 CDC Agreement Objectives (6) Collaborate with UC in developing training programs.Develop technical plans for an electronic standards-based tracking networkData transferData linkageSecurityDisseminationIntegration with other systems
18 CDC Agreement Objectives (6) Develop an outreach and education strategy for communicating informationDeveloping and evaluating communication strategiesConduct a pilot project that will track asthma prevalence and adverse pregnancy outcomes and link to hazard data on traffic exhaust exposures.
19 Planning Consortium Composed of representation from: U.S. EPA, UC, Cal/EPA, CDHS technical experts (e.g. CCR, EHL)County/tribal health/environmental officialsHealth care providersEnvironmental GroupsNGOs, CBOs

21 Recommendations of CDC Technical Workgroup Env. Health Surveillance System (EHSS) should be developed in cooperation with NEDSSEHSS should consist of a network of distributed data sources, which could send or receive data.EHSS should adopt metadata standards that permit standardized search for all sourced info.
22 Recommendations of CDC Technical Workgroup Architects of EHSS should work with federal partners and private standard-setting organizations to share, create, modify data, and develop process, performance and technology standards.Architects should adopt a formal technology neutral methodolgy for modeling, analysis and design of the EHSS.EHSS should identify, integrate, and make available tools for data analysis, interpretation, and presentation.
23 Recommendations of CDC Technical Workgroup Architects should explore developing relationship with private providers to gain access to non-traditional surveillance/tracking sources.Architects should ensure that there are data sharing agreements between relevant agencies at state and federal levels.Architects should develop a comprehensive IT security plan and include technical specifications.
24 CA Env. Health Tracking Pilot Goals To examine the feasibility of tracking routinely available data on asthma and adverse pregnancy outcomesTo identify elevated “hotspot” areas of concern of these health outcomes and traffic-related pollutants
25 CA Env. Health Tracking Pilot Goals To explore GIS methods of mapping and linking pollution and health data for health communication and data dissemination for local stakeholders (i.e. Pacific Institute, West Oakland, Alameda County)To assist local health departments in planning and allocation of resources

31 Key Challenges/Opportunities Strategies to expand/build tracking network in era of severe state budget cutsNeed to produce timely information on hazards/health outcomes that are useful to local stakeholdersHow to engage/involve local communities on tracking activitiesHow to promote closer involvement/collaboration of environmental agencies
