Performance of a Syndromic Surveillance System for Detecting Carbon Monoxide Poisoning Following a Severe Windstorm
Content Type: Abstract
On December 14th, 2006, a severe windstorm in western Washington caused hundreds of thousands of residents to lose power. On December 15, 2006, there was a surge in emergency department (ED) visits for patients presenting with signs… read more… the storm to determine the extent of CO poisoning due to the windstorm. A retrospective analysis was later … the storm to deter- mine the extent of CO poisoning due to the wind- storm. A retrospective analysis was later … and diagnoses. Records from two hospitals (n=10) which did not participate in our syndromic surveillance system … -
Monitoring Staphylococcus Infection Trends with Biosurveillance Data
Content Type: Abstract
Methicillin resistant staphylococcus aureus (MRSA) is a leading cause of skin and soft tissue infections (SSTI). Until recently, S. aureus pneumonia has been considered primarily a nosocomial infection, and was reported… read more… annual trend in the proportion of PI admissions due to S. aureus. Almost half (47.8%) of patients … in the proportion of SSTI diagnoses at EDs. However, we did not find an increasing annual trend in S. aureus … -
Syndromic Surveillance for Influenza in Washington State: A Local and Regional Perspective
Content Type: Abstract
We explored the utility of tracking emergency department (ED) visits for febrile illness as a proxy for influenza surveillance, from both a local and a regional perspective.… was lowest compared with King and Pierce counties and did not correlate as strongly with data from these two … the 5-17 year old age group (r=.84); the correlation for all other age groups was less than .65. CONCLUSIONS ED fever … activity, including laboratory influenza test results and all cause school absenteeism. ED fever visit trends for … -
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.… through 4/28/2007 and excluded one hospital that did not provide ED chief com- plaints. The weekly number of … including data from the diagnosis, where available, did not consistently improve the SNR.

Systematic Comparison of Algorithms Used in Syndromic Surveillance
Content Type: Abstract
Varied approaches have been used by syndromic surveillance systems for aberration detection. However, the performance of these methods has been evaluated only across a small range of epidemic characteristics. Objective… read more… visits per day. We then simulated epidemics by creating all possible combinations of 3 different parameters: … syndrome. RESULTS Overall, timeliness was similar for all algorithms, with time to detection ranging between 2 and … after the start of the outbreak. When averaged across all outbreak parameters, the GLM had the best sensi- tivity …
