  • Scalable Detection of Irregular Disease Clusters Using Soft Compactness Constraints

    Content Type: Abstract

    The spatial scan statistic [1] detects significant spatial clusters of disease by maximizing a likelihood ratio statistic F(S) over a large set of spatial regions, typically constrained by shape. The fast localized scan [2] enables scalable… read more

  • Using Syndromic Emergency Department Data to Augment Oral Health Surveillance

    Content Type: Abstract

    Using the chief complaint field from our established syndromic ED system, we developed definitions for potentially preventable oral health visits (OHV) and examined patterns in 2009-2011 data. Under the widest definition, OHV comprised about 1% of… read more

  • Accurate Detection of Arbitrarily-Shaped Spatial Disease Clusters

    Content Type: Abstract

    Methods for locating spatial clusters of diseases are typically variations of the circular scan statistic method. They restrict the number of potential clusters by considering all circular, rectangular, or elliptical regions, and then apply a… read more
