SyCo: A Probabilistic Machine Learning Method for Classifying Chief Complaints into Symptom and Syndrome Categories
Content Type: Abstract
Scientists have utilized many chief complaint (CC) classification techniques in biosurveillance including keyword search, weighted keyword search, and naïve Bayes. These techniques may utilize CC-to-syndrome or CC-… read more… Scientists have utilized many chief complaint (CC) classification techniques in biosurveillance … search, and naïve Bayes. These techniques may utilize CC-to-syndrome or CC-to-symptom-to-syndrome classification approaches. In the … BACKGROUND Scientists have utilized many chief complaint (CC) classification techniques in biosurveillance including … -
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). The current… read more… to incomplete, delayed reporting. Chief complaint (CC) based surveillance is limited in that a patient’s … the cost, delays, incompleteness and low specificity (for CC) in current methods of influenza surveillance is … to incomplete, delayed reporting. Chief complaint (CC) based surveillance is limited in that a patient’s chief … -
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… immediate, and ELR is delayed 7 days from initial patient visit. A plausible solution, a middle way, to the extremes … mediate, and ELR is delayed 7 days from initial patient visit.1 A plausible solution, a middle way, to the extremes … Figure 1 shows chart of percent daily expected ED flu visits from July to December of 2009. Average daily ED … -
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… the following formula, which assumes that TS and ED visits are proportional to population size (pop) and that … symptoms (referred to as constitutional counts, CC) of people who come to EDs as a rough surrogate of ED flu … of predicting outcomes that are related to flu ED visits based on TS. Our results suggest that the use of TS, … -
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… (over-the-counter (OTC) sales, Emergency Department visits, etc.) to detect both natural disease outbreaks (e.g. … multiple data streams (OTC sales, Emergency Department visits, etc.) to detect both natural disease outbreaks (e.g. … (over-the-counter (OTC) sales, Emergency Department visits, etc.) to detect both natural disease outbreaks (e.g. …
