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.

Developing an application ontology for mining clinical reports: the extended syndromic surveillance ontology
Content Type: Abstract
Ontologies representing knowledge from the public health and surveillance domains currently exist. However, they focus on infectious diseases (infectious disease ontology), reportable diseases (PHSkbFretired) and internet surveillance… read more… University of Pittsburgh, Pittsburgh, PA, USA E-mail: michaelambroseconway@gmail.com Objective To develop an application ontologyFthe … -
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… University of Pittsburgh, Pittsburgh, PA, USA E-mail: wendy.w.chapman@gmail.com Objective Adapt an existing natural language … -
Evaluating Syndrome Definitions in the Extended Syndromic Surveillance Ontology
Content Type: Abstract
The Extended Syndromic Surveillance Ontology (ESSO) is an open source terminological ontology designed to facilitate the text mining of clinical reports in English [1,2]. At the core of ESSO are 279 clinical concepts (for example, fever, confusion,… read more… J Am Med Inform Assoc. 2010;17:595�601. *Mike Conway E-mail: michaelambroseconway@gmail.com (page number not for citation purpose) Table 1. … -
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… Allegheny County Health Department, Pittsburgh, PA, USA E-mail: tsui2@pitt.edu Objective This paper describes an … a 6-month time series graph of the percentage of total ED visits per day with ILI detected by the rule-based logic. … of the UPMC Health System.

Modeling Clinician Detection Time of a Disease Outbreak Due to Inhalational Anthrax
Content Type: Abstract
We developed a probabilistic model of how clinicians are expected to detect a disease outbreak due to an outdoor release of anthrax spores, when the clinicians only have access to traditional clinical information (e.g., no computer-based alerts). We… read more… is only seen by a health care provider once (no return visits) and each clinician diagnoses a given case of IA …
