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 … by summing the posterior probability for flu for each visit.

Data quality in federated disease surveillance: using variability as an indicator of quality
Content Type: Abstract
Most, if not all, disease surveillance systems are federated in the sense that hospitals, doctors’ offices, pharmacies are the source of most surveillance data. Although a health department may request or mandate that these… read more… of quality control.

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… Pittsburgh, PA, USA E-mail: wendy.w.chapman@gmail.com Objective Adapt an existing natural language processing … caused less by NLP technicalities than they are by the lack of a robust environment for NLP engineering, … -
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… !
