    Content Type: Abstract

    Health care information is a fundamental source of data for biosurveillance, yet configuring EHRs to report relevant data to health departments is technically challenging, labor intensive, and often requires custom solutions for each installation.… read more

  • Traveling Epidemic Waves in Biosurveillance Data: Identifying Early Hotspots of Respiratory Illness

    Content Type: Abstract

    We have previously shown that timeliness of detection is influenced both by the data source (e.g., ambulatory vs. emergency department) and demographic characteristics of patient populations (e.g., age). Because epidemic waves are thought to… read more

  • Privacy Protection versus Cluster Detection in Spatial Epidemiology

    Content Type: Abstract

    With the widespread deployment of near real time population health monitoring, there is increasing focus on spatial cluster detection for identifying disease outbreaks. These spatial epidemiologic methods rely on knowledge of patient location to… read more
