Challenges in adapting an natural language processing system for real-time surveillance
Content Type: Abstract
We are developing a Bayesian surveillance system for realtime surveillance and characterization of outbreaks that incorporates a variety of data elements, including free-text clinical reports. An existing natural language processing (… read more… language processing system for real-time surveillance WW Chapman, M Conway, JN Dowling, F-C Tsui, Q Li, LM … Journal 2011, 4:s68. doi: 10.3134/ehtj.10.068 & 2011 WW Chapman et al.; licensee Emerging Health Threats Journal. www.eht-journal.org 7 challenges are caused less by NLP … -
Monitoring Pharmacy Retail Data for Anomalous Space-Time Clusters
Content Type: Abstract
Bio-surveillance systems monitor multiple data streams (over-the-counter (OTC) sales, Emergency Department visits, etc.) to detect both natural disease outbreaks (e.g. influenza) and bio-terrorist attacks (e.g. anthrax re-lease). Many detection… read more… impressive results under simulated environments, but the com- plex behavior of real-world data and high costs asso- … can access alerts online on the SSS website, add and view com- ments on each alert, and select which alerts they want … Maheshkumar R.

An automated influenza-like-illness reporting system using freetext emergency department reports
Content Type: Abstract
Current methods for influenza surveillance include laboratory confirmed case reporting, sentinel physician reporting of Influenza-Like-Illness (ILI) and chief-complaint monitoring from emergency departments (EDs).

Estimating the incidence of influenza cases that present to emergency departments
Content Type: Abstract
Our laboratory previously established the value of over-the-counter (OTC) sales data for the early detection of disease outbreaks. We found that thermometer sales (TS) increased significantly and early during influenza (flu) season.… read more… (referred to as constitutional counts, CC) of people who come to EDs as a rough surrogate of ED flu cases.

Building an automated Bayesian case detection system
Content Type: Abstract
Current practices of automated case detection fall into the extremes of diagnostic accuracy and timeliness. In regards to diagnostic accuracy, electronic laboratory reporting (ELR) is at one extreme and syndromic surveillance is at… read more… Tsui et al.; licensee Emerging Health Threats Journal. www.eht-journal.org 68 Acknowledgements The project is … Health Threats Journal F-C Tsui et al. 2011, 4:s101 www.eht-journal.org page 2/2 69 … -
A data simulation model using NRDM pharmaceutical sales counts
Content Type: Abstract
In disease surveillance, an outbreak is often present in more than one data type. If each data type is analyzed separately rather than combined, the statistical power to detect an outbreak may suffer because no single data source… read more… and F-C Tsui.; licensee Emerging Health Threats Journal. www.eht-journal.org 5353 distribution.
