Novel approach to hypoglycemia surveillance in an international online diabetes social network
Content Type: Abstract
Hypoglycemia is a serious sequela of diabetes treatment that is not tracked by current health surveillance efforts despite substantial related morbidity and mortality. We take a novel approach to hypoglycemia surveillance, engaging members of an… read more… Shamoon H. Hypoglycemia in diabetes. Diabetes Care. 2003;26:1902�12. 2.

State Surveillance Data Improves a Clinical Prediction Model for Pertussis
Content Type: Abstract
Bordetella Pertussis outbreaks cause morbidity in all age groups, but the infection is most dangerous for young infants. Pertussis is difficult to diagnose, especially in its early stages, and definitive test results are not… read more… Bordetella Pertussis outbreaks cause morbidity in all age groups, but the infection is most dangerous … Bordetella Pertussis outbreaks cause morbidity in all age groups, but the infection is most dangerous for … date exceeded 0.09 (13% sensitive, 53% specific, PPV 26%, NPV 94%, AROC 0.65).

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… restrict the number of potential clusters by considering all circular, rectangular, or elliptical regions, and then … area, certain sub-graphs are evaluated.

Improving Detection Timeliness by Modeling and Correcting for Data Availability Delays
Content Type: Abstract
The performance of even the most advanced syndromic surveillance systems can be undermined if the monitored data is delayed before it arrives into the system. In such cases, an outbreak may be detected only after it is too late for appropriate… read more… adjusted by the variance of the availability models. For all three approaches, we set a benchmark specificity of 95%. … 1) yields good detection sensitivity but poor timeliness, due to the delays in data availability.
