Empirical/Asymptotic P-Values for Monte Carlo-Based Hypothesis Testing: An Application to Cluster Detection Using the Scan Statistic
Content Type: Abstract
SaTScan is a freely available software that uses the scan statistic to detect clusters in space, time or space-time. SaTScan uses Monte Carlo hypothesis testing in order to produce a p-value for the null hypothesis that no… read more… to gener- ate each p-value while still retaining enough preci- sion in the p-value to determine how unusual a clus- … Communications in Sta- tistics: Theory and Methods, 1997. 26: p. 1481-1496.

Telephone Triage Data for Detection of Influenza-like Illness
Content Type: Abstract
National surveillance is used to detect the emergence and spread of influenza virus variants and to monitor influenza-related morbidity and mortality. Nurse telephone triage (“call”) data may serve as a useful complement to… read more… and mortality.

It may also be useful to detect increased occurrence … morbidity and mortality. Nurse call data may serve as a useful complement to traditional influenza … -
Nurse Call Data for Detection of Influenza-Like Illness
Content Type: Abstract
Influenza affects millions of people and causes about 36,000 deaths in the United States each winter. Pandemics of influenza emerge at irregular intervals. National influenza surveillance is used to detect the emergence and spread of influenza virus… read more… such data for influenza-like illness (ILI) surveillance may lead to earlier detection of ILI in the community, both because people with ILI may call a nurse line before seeking care at a health-care … manual data entry. Using such data for ILI surveil- lance may lead to earlier detection of ILI in the community, both … -
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… For each data stream— AC, ED, and AC+ED combined—repeat visits were omitted if they occurred within 6 weeks of a previous visit to the same setting for LGI. Generalized linear mixed … -
in silico Surveillance: Highly detailed agent-based models for surveillance system evaluation and design
Content Type: Abstract
Modern public health surveillance systems have great potential for improving public health. However, evaluating the performance of surveillance systems is challenging because examples of baseline disease distribution in the population are limited to… read more… seeking behavior and a surveillance system for outpatient visits.

Multi-Method Comparison of Detecting Common Events of Public Health Interest: a Multi-Site, Multi-Stream Simulation Study
Content Type: Abstract
Existing statistical methods can perform well in detecting simulated bioterrorism events. However, these methods have not been well-evaluated for detection of the type of respiratory and gastrointestinal events of greatest… read more… Demonstration Program [4] from June 2005 through May 2006.
