Modifications to Spatial Scan Statistics for Estimated Probabilities at Fine-Resolution in Highly Skewed Spatial Distributions
Content Type: Abstract
Estimation of representative spatial probabilities and expected counts from baseline data can cause problems in applying spatial scan statistics when observed events are sparse in a large percentage of the spatial zones (e.g.,… read more… the cho- sen syndrome groups from the Texas DoD clinic visit counts at the residence-zip code and home-zip code … -
Adopting a common influenza-like illness syndrome across multiple health jurisdictions
Content Type: Abstract
Syndromic surveillance systems were designed for early outbreak and bioterrorism event detection. As practical experience shaped development and implementation, these systems became more broadly used for general surveillance and situational… read more… historical data consisting of total and ILI-related daily visit counts by age group (B2, 2�4, 5�17, 18�44, 45�64 and … -

Another Type of Cluster Monitoring: Detection of Groups of Anomalous Patient Residence Locations
Content Type: Abstract
The Veterans Health Administration (VHA) uses the Electronic Surveillance System for the Early Notification of Community-based Epidemics to detect disease outbreaks and other health-related events earlier than other forms of surveillance. Although… read more… by ICD-9 code and chart review), date and location of visit and patients’ zip code of residence. We also accessed … -

Data-Adapted Temporal Alerting Algorithms for Routine Health Monitoring
Content Type: Abstract
This paper discusses selection of temporal alerting algorithms for syndromic surveillance to achieve reliable detection performance based on statistical properties and the epidemiological context of the input data. We used quantities calculated from… read more… signals. Sensitivity values were recorded for practical back- ground alert rates to compare algorithm detection … -
Utility of Syndromic Surveillance for Investigating Morbidity Resulting from a Severe Weather Event
Content Type: Abstract
On 12/14/06, a windstorm in western Washington caused 4 million residents to lose power; within 24 hours, a surge in patients presented to emergency departments (EDs) with carbon monoxide (CO) poisoning. As previously described, records of… read more… possibly resulting from ingestion of food spoiled by lack of refrigeration, were detected in the ED data but not … -
