Comparison of Aberration Detection Algorithms for Biosurveillance Systems
Content Type: Abstract
Use of robust and broadly applicable statistical alerting methods is essential for a public health Biosurveillance system. We compared several algorithms related to the Early Aberration Reporting System C2 (adaptive control chart) method for… read more… daily volume of facility visits. Adjustment for the total visit volume allows monitoring of surrogate rates instead of … and the use of real data with both syndromic and total visit counts enables this adjustment. Objective We compared … daily volume of facility visits. Adjustment for the total visit volume allows monitoring of surrogate rates instead of … -
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… has the added complication that day-of-week clinical visit patterns differ widely, (e.g. clinic closure on … has the added complication that day-of-week clinical visit patterns differ widely, (e.g. clinic closure on … -
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… and death, but fatalities are rare and many DoD clinics lack admitting capability, so we sought to derive additional … and death, but fatalities are rare and many DoD clinics lack admitting capability, so we sought to derive additional … -
Cross Disciplinary Consultancy: Negation Detection Use Case
Content Type: Abstract
Despite considerable effort since the turn of the century to develop Natural Language Processing (NLP) methods and tools for detecting negated terms in chief complaints, few standardised methods have emerged. Those methods that have emerged (e.g.… read more… with customised solutions. Important reasons for this lack of progress include (a) limited shareable datasets for … with customised solutions.
