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

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;

Slide 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
