NC DETECT as innovation• Catalyst
– Bioterrorism and natural disasters
• New approach– Secondary use of existing data– Standardization: data formatting and transmission
• “Bonus”– Flexibility (w. triage notes)– Communication (Annotation left by analysts)– Environmental exposure monitoring (Poison Center calls)– National biosurveillance player
• Challenges– Mandate; Standardization; Maintenance budget
• Next Steps– Urgent care centers; Ambulance run data; Sustainable funding
