Practical comparison of aberration detection algorithms for biosurveillance systems.
Journal of Biomedical Informatics(2015)
摘要
•We used syndromic data from 62 VHA hospitals and simulated alerting signals.•We compared 7 detection methods on sensitivity and timeliness of alerting.•Weekday/weekend stratification improved detection performance.•Total visit adjustment increased sensitivity and timeliness.•A Poisson regression provided the best sensitivity for high-count data.
