Clustering under the Null: One Reason for Too Many Signals
Content Type: Abstract
I examine the nature and expression of the null hypothesis often used in spatial surveillance. I also show an example of how incorrect specification of the null can lead to excess signals without interesting outbreaks, and argue that this may be a… read more -
Combining Laboratory Test Orders and Outpatient Visits to Monitor Respiratory Illness
Content Type: Abstract
To evaluate whether joint monitoring of laboratory test orders and outpatient visits improves the sensitivity and timeliness of alerting during seasonal increases in respiratory illness. -
Comparing Syndromic Surveillances using Two Aspects: Emergency and Telehealth Data Sources
Content Type: Abstract
The objective of this paper is to examine the utility of Emergency Department and Telehealth data for Syndromic Surveillance. This works attempts to minimize false outbreak detection. It also demonstrates that these two data sources contain… read more -
