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… syndromes having average daily counts of 2, 10, 35 and 50 visits per day. We then simulated epidemics by creating all … -
GraphScan: Detection and Analysis of Free-Form Spatio-Temporal Patterns
Content Type: Abstract
By capturing the spatio-temporal organization of the data using a graph, GraphScan avoids the challenges associated with trying to “fit” incoming data into moving windows of predefined shapes and sizes. Whereas the popular space-time permutation… read more… to the level of “activity” (e.g., count of GI-related ED visits) for the corresponding region and time period. … -
Chart Review of Laboratory-Confirmed Salmonella Enteritidis Cases in a Local Food Borne Outbreak Linked to Mung Bean Sprouts
Content Type: Abstract
A retrospective chart review was performed to examine chief complaint, syndrome classification and discharge diagnoses of laboratory confirmed Salmonella Enteritidis phage type (PT) 13 cases who visited the Emergency Departments (ED) of two local… read more… Division. The RODS-based system captures real-time ED visits from 7 area hospitals and real-time admissions from 3 … -
A Nonparametric Scan Statistic for Multivariate Disease Surveillance
Content Type: Abstract
We present a new method for multivariate outbreak detection, the ìnonparametric scan statisticî (NPSS). NPSS enables fast and accurate detection of emerging space-time clusters using multiple disparate data streams, including nontraditional data… read more… into five Allegheny County datasets: respiratory ED visits, three streams of OTC data (cough/cold, antifever, … -
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… our syndromic surveillance system captured 16,982 ED visits. Most of the 169 ED patients with CO-related illness … -
What is the Value of a Positive Syndromic Surveillance Signal?
Content Type: Abstract
One criterion for evaluating the effectiveness of a surveillance system is the system’s positive predictive value. To our knowledge few studies have described the positive predictive value of syndromic surveillance signals… read more… departments (EDs) in King County. EDs send data on all visits that occurred the previous day. Aberrations in the … -
Tuberculosis Surveillance, Republics of Armenia and Georgia, 2003-2004
Content Type: Abstract
The former Soviet Union (FSU)—through the Sanitary-Epidemiologic Service (SES)—developed an extensive system of disease surveillance that was effective, yet centrally planned in Moscow. Even after the fall of the FSU in 1991,… read more… Central TB staff provided direct supervision with regular visits (at least 1-2 times per year) to each of the TB …
