Identifying Categories of Over-the-Counter Products with Superior Outbreak Detection Performance
Content Type: Abstract
A significant research topic in biosurveillance is how to group individual events—such as single emergency department (ED) visits and sales of over-thecounter healthcare (OTC) products—into counts of “similar” events. For OTC products, the goal is… read more… data and applied it to OTC product sales data and ED ILI visit data in southwest- ern PA. The dataset of OTC sales … -
Learning Outbreak Regions for Bayesian Spatial Biosurveillance
Content Type: Abstract
This work incorporates model learning into a Bayesian framework for outbreak detection. Our method learns the spatial characteristics of each outbreak type from a small number of labeled training examples, assuming a generative outbreak model with… read more… outbreaks injected into real-world Emergency Department visit data from Allegheny County, PA. In the simulations … -
A Novel, Context-Sensitive Approach to Anonymizing Spatial Surveillance Data: Impact on Outbreak Detection
Content Type: Abstract
The use of spatially-based methods and algorithms in epidemiology and surveillance presents privacy challenges for researchers and public health agencies. We describe a novel method for anonymizing individuals in public health datasets, by… read more… (ED) visits for respiratory illness. Baseline ED visit data were in- jected with artificially-created … -
A Pilot Study of Aberration Detection Algorithms with Simulated Data
Content Type: Abstract
To evaluate four algorithms with varying baseline periods and adjustment for day of week for anomaly detection in syndromic surveillance data. read more… for detecting anomalies in daily emergency depart- ment visit data for 130 hospitals with 6 syndrome categories. … -
Absenteeism Among Employees in a Southeastern Ontario Hospital: A Novel Application of Syndromic Surveillance
Content Type: Abstract
Sickness absence is particularly pronounced within health care organizations where job demands and work environment expose workers to an increased risk of illness and injury, potentially leading to an inability to attend work.… read more… the databases. The conditions/ syndromes within the OH visit data are pre- determined by the system, and classified … -
Comparing Telehealth and NACRS Influenza Activity to Fluwatch Surveillance Using EARS-X
Content Type: Abstract
This paper will use CDCÃs EARS-X to examine Tele-healthÃs potential as an early warning system specifically for influenza-like illness compared to NACRS, as well as qualitatively comparing the resultant EARS flags to peaks in influenza activity… read more… since 2000. For the purpose of this paper, only ED visit portion of the dataset was included in the analysis. … -
A Case Manager Tool for Anomaly Investigation in BioSurveillance
Content Type: Abstract
Effective anomaly detection depends on the timely, asynchronous generation of anomalies from multiple data streams using multiple algorithms. Our objective is to describe the use of a case manager tool for combining anomalies into cases, and for… read more… New York, for the years 1996-2005. The record for each visit includes hospital, patient geography … -
A Comparison of Ambulatory Care and Emergency Department Encounters as Data Sources for Detection of Clusters of Lower Gastrointestinal Illness
Content Type: Abstract
We sought to compare ambulatory care (AC) and emergency department (ED) data for the detection of clusters of lower gastrointestinal illness, using AC and ED data and AC+ED data combined, from two geographically separate health plans participating… read more… omitted if they occurred within 6 weeks of a previous visit to the same setting for LGI.
