  • The Day-of-the-Week Effect: A Study Across the Indiana Public Health Emergency Surveillance System

    Content Type: Abstract

    Complex, highly parameterized data models are often used to detect syndromic outbreaks. Unfortunately, such models can pose greater maintenance challenges as parameter variations increase. As such, our work focuses on whether day… read more

To compare across hospitals, we normalized the … or insignificantly across data sources. We found that visit rates by syndrome varied significantly by DoW Further, …
  • Operational Considerations and Early Successes with a Statewide Public Health Surveillance System

    Content Type: Abstract

    In 2004, the Indiana State Department of Health (ISDH) partnered with the Regenstrief Institute to begin collecting syndromic data from 14 ED’s to monitor bioterrorism-related events and other public health emergencies. Today, Indiana’s public… read more

  • Evaluating the Performance of a Spatial Scan Statistic Using Simulated Outbreak Characteristics

    Content Type: Abstract

    Research evaluating the use of spatial data for surveillance purposes is ongoing and evolving. As spatial methods evolve, it is important to characterize their effectiveness in real-world settings. Assessing the performance of… read more

  • An Evaluation of Electronic Laboratory Data Quality and a Health Information Exchange

    Content Type: Abstract

    Electronic laboratory reporting (ELR) was demonstrated just over a decade ago to be an effective method to improve the timeliness of reporting as well as the number of reports submitted to public health agencies. The quality of data (inc.… read more

  • Privacy Protection versus Cluster Detection in Spatial Epidemiology

    Content Type: Abstract

    With the widespread deployment of near real time population health monitoring, there is increasing focus on spatial cluster detection for identifying disease outbreaks. These spatial epidemiologic methods rely on knowledge of patient location to… read more
    … tions, significant clusters contained fewer additional ED visit points (i.e., points that were not part of the … in small circle) and few additional points from the ED visits (red dots outside small circle). However, when the … with points at zip code centroids (right), many more ED visits were included in the detected cluster. CONCLUSIONS …
  • A Novel, Context-Sensitive Approach to Anonymizing Spatial Surveillance Data: Impact on Outbreak Detection

    Content Type: Abstract

    The use of spatially-based methods and algorithms in epidemiology and surveillance presents privacy challenges for researchers and public health agencies. We describe a novel method for anonymizing individuals in public health datasets, by… read more

  • Patient Management System Programmed Alert to Notify Providers of Suspected TB Cases

    Content Type: Abstract

    An increase in tuberculosis (TB) among homeless men residing in Marion County, Indiana was noticed in the summer of 2008. The Marion County Public Health Department (MCPHD) hosted screening events at homeless shelters in hopes of finding… read more
