Evaluation of Body Temperature to Classify Influenza-Like Illness (ILI) in a Syndromic Surveillance System
Content Type: Abstract
This study aims to evaluate the sensitivity, specificity and Positive Predictive Value (PPV) of body temperature measurements > 100.5 F in relationship to laboratory confirmation of influenza and other ILI pathogens.… For each of ten codes used to profile the ILI syndrome in ESSENCE (the Department of Defense’s syndromic surveillance … -
The NGram CC Classifier: A Novel Method of Automatically Creating CC Classifiers Based on ICD9 Groupings
Content Type: Abstract
Syndromic surveillance of emergency department (ED) visit data is often based on computer algorithms which assign patient chief complaints (CC) to syndromes. ICD9 code data may also be used to develop visit classifiers for syndromic surveillance but… read more… visits). We used as our ICD9 classifier an existing ESSENCE filter for “lower GI” modified by removing … -
