An Empirical Comparison of Spatial Scan Statistics for Outbreak Detection
Content Type: Abstract
We present a systematic empirical comparison of five recently proposed expectation-based scan statistics, in order to determine which methods are most successful for which spatial disease surveillance tasks. -
An Empirical Study of the Effect of Sentinel Sample Size in Syndromic Surveillance Using a Space-Time Permutation Method
Content Type: Abstract
Our goal was to assess the impact of sentinel sample size and criteria for a signal on performance of daily prospective space-time permutation detection by comparing results in varying size random samples from a large health plan to results found in… read more -
An Evaluation of Wavelet-Based Techniques for Prediction and Anomaly Detection in Univariate Syndromic Data
Content Type: Abstract
While several authors have advocated wavelets for biosurveillance, there are few published wavelet method evaluations using real syndromic data. Goldenberg et al. performed an analysis using wavelet predictions as a way of detecting a… read more -
An Examination of Syndromic Surveillance for Early Detection of Nosocomial Outbreaks
Content Type: Abstract
So as to be able to detect nosocomial outbreaks at an early stage, we examine the construction of a syndromic surveillance system for inpatients who have fever, respiratory symptoms, diarrhea, vomiting or rash and evaluate its statistical properties. -
An Expectation-Based Scan Statistic for Detection of Space-Time Clusters
Content Type: Abstract
This paper describes a new class of space-time scan statistics designed for rapid detection of emerging disease clusters. We evaluate these methods on the task of prospective disease surveillance, and show that our methods consistently outperform… read more -
An Experimental Fully Automatic Syndromic Surveillance in Japan
Content Type: Abstract
Since we donÃt know when such a disaster may occur, we have to perform this syndromic surveillance routinely, and thus the system should be automatic. Namely, information is drawn from electronic medical records (EMR), and is statistical analyzed,… read more -
An Innovative Design for Conducting Simulation Exercises on Electronic Disease Surveillance System
Content Type: Abstract
In order to be best prepared to identify health events using electronic disease surveillance systems, it is vital for users to participate in regular exercises that realistically simulate how events may present in their system following disease… read more -
Enhanced Aedes spp. surveillance across jurisdictions in Arizona’s border region
Content Type: Abstract
As part of a statewide effort to enhance surveillance for Aedes spp.mosquitoes the Office of Border Health (OBH) took the lead inproviding technical assistance on surveillance in counties bordering Mexico. In 2016, OBH sought ways to enhance… read more
