Choice of Baseline Period for Limited Baseline Aberration Detection Methods
Content Type: Abstract
This paper evaluates the operating characteristics of limited baseline aberration detection methods using different lengths (7-28 days) and end dates (1-7 days prior to the current day) for the baseline period using simulated outbreaks added to real… read more -
Classification of Emergency Department Syndromic Data for Seasonal Influenza Surveillance
Content Type: Abstract
We evaluated several classifications of emergency department (ED) syndromic data to ascertain best syndrome classifications for ILI. -
Clostridium Difficile, Surveillance Using Laboratory Data from BioSense Hospitals
Content Type: Abstract
To determine the feasibility of using BioSense laboratory data to do surveillance on Clostridium difficile infection (CDI) and calculate overall and facility rates of disease. -
Cluster Detection Incorporating Lagged Test Data
Content Type: Abstract
Using New York CityÃs dead bird surveillance for West Nile Virus (WNV), this paper presents two explorations of the spatial cluster detection problem in which lagged test results are available for a random subset of observations. First, we… read more -
Clustering under the Null: One Reason for Too Many Signals
Content Type: Abstract
I examine the nature and expression of the null hypothesis often used in spatial surveillance. I also show an example of how incorrect specification of the null can lead to excess signals without interesting outbreaks, and argue that this may be a… read more -
Combining Laboratory Test Orders and Outpatient Visits to Monitor Respiratory Illness
Content Type: Abstract
To evaluate whether joint monitoring of laboratory test orders and outpatient visits improves the sensitivity and timeliness of alerting during seasonal increases in respiratory illness. -
Comparing Syndromic Surveillances using Two Aspects: Emergency and Telehealth Data Sources
Content Type: Abstract
The objective of this paper is to examine the utility of Emergency Department and Telehealth data for Syndromic Surveillance. This works attempts to minimize false outbreak detection. It also demonstrates that these two data sources contain… read more -
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
