  • Tuning a Chief Complaint Text Parser for Use in DoD ESSENCE

    Content Type: Abstract

    An expanded ambulatory health record, the Comprehensive Ambulatory Patient Encounter Record (CAPER) will provide multiple types of data for use in DoD ESSENCE. A new type of data not previously available is the Reason for Visit (ROV), a free-text… read more

  • A Term-based Approach to Asyndromic Determination of Significant Case Clusters

    Content Type: Abstract

    Biosurveillance systems commonly depend on free-text chief complaints (CC)s for timely situational awareness. However, diagnosis codes may not be available soon enough and may have uncertain value because they are assigned for billing purposes… read more

  • Analytic Biosurveillance Methods for Resource-Limited Settings

    Content Type: Abstract

    Biosurveillance in resource-limited settings is essential because of both enhanced risk of diseases rarely seen elsewhere (e.g. cholera) and pandemic threats (e.g. avian influenza). However, access to care and laboratory test capability are… read more

  • Use of Severity Indicators in a Public Health Surveillance System

    Content Type: Abstract

    Data streams related to case severity have been added to the Electronic Surveillance System for the Early Notification of Community-based Epidemics (ESSENCE), a disease-monitoring application used by the Department of Defense (DoD), as an additional… read more

  • Development and Evaluation of a Data-adaptive Algorithm for Univariate Temporal Biosurveillance Data

    Content Type: Abstract

    Numerous recent papers have evaluated algorithms for biosurveillance anomaly detection. Common essential problems in the disparate, evolving data environment include trends, day-of-week effects, and other systematic behavior.… read more

  • Evaluation of Alerting Sparse-Data Streams of Population Healthcare-Seeking Data

    Content Type: Abstract

    Objective This presentation discusses the problem of detecting small-scale events in biosurveillance data that are relatively sparse in the sense that the median count of monitored time series values is zero. Research goals are to understand… read more

  • Refinement of a Population-Based Bayesian Network for Fusion of Health Surveillance Data

    Content Type: Abstract

    The ESSENCE demonstration module was built to help DoD health monitors make routine decisions based on disparate evidence sources such as daily counts of ILI-related chief complaints, ratios of positive lab tests for influenza, patient age… read more
