  1. Population Health and EHRs: Seeing the Forest for the Trees Dr. Aneel Advani Nat’l Center for Public Health Informatics/Centers for Disease Control and Prevention Tuesday, September 15, 2009

  2. EHRs and Public Health:Sentinel vs. Large-Scale Surveillance • Status quo: Manual sentinel providers; long-standing relationships • EHRs: “Large-scale surveillance” – high fractions of total healthcare transactions available • Issues: indicators vs. raw data, (cross)-validation, signal-to-noise; analytics capacity; semantic heterogeneity; causal chains; visualization; multi-scale perspectives; state and local vs. federal needs Source: CDC Influenza Division Dr. Aneel Advani

  3. EHRs and Public Health:Registry-based information networks • Current EHR concept: EHR to population health – messaging or CDA from raw transactional systems • Where we need to go: condition-specific or event-based registries • Issues: counts vs. rates; de-duplication and aggregation; query protocols; last-mile connectivity; interoperability; Source: CDC Div. Cancer Control Dr. Aneel Advani

  4. EHRs and Public Health:Health-information orgs (HIOs) • Current EHR concept: EHRs have horizontal whole-patient perspective • Alternate model for information exchange: vertical information flows specific to PH • Issues: interoperability; legacy systems and standards; business models / mandates for specific HIOs/information flows; integration with full-service EHRs; participation on NHIN Source: APHL Dr. Aneel Advani
