EpiS3: a semantically interoperable social network for syndromic surveillance and disease control
Luciana Tricai Cavalini and Timothy Wayne CookNational Institute of Science and Technology – Medicine Assisted by Scientific Computing
Summary
• The problem• The current solution• Remaining challenges• A new approach• Implementation• Future steps
The Current Solution: Issues
• Top-down data models– Risk of inaccurate or incomplete data
• Hospital/clinic centered applications– No records from uncovered populations
• Incipient Decision Support Systems (DSS)– Mostly academic projects in internal medicine
Remaining Questions• How to collect data in the most opportune
moment?– At the point of care– In the household
• How to get data with proper…– ...accuracy...– ...granularity...
• ...that will allow implementation of useful DSS for syndromic surveillance?

EpiS3: Future Steps
• App User Interface– Desktop and mHealth versions
• DSS Algorithms– Clinical evaluation– Messaging– Reporting
• EpiInfo Form Builder for MLHIM data
