BACKGROUND: China Centre for Diseases Control and Prevention (CDC) developed the
China Infectious Disease Automated Alert and Response System (CIDARS) in 2005.
The CIDARS was used to strengthen infectious disease surveillance and aid in the
early warning of outbreak. The CIDARS has been integrated into the routine
outbreak monitoring efforts of the CDC at all levels in China. Early warning
threshold is crucial for outbreak detection in the CIDARS, but CDCs at all level
are currently using thresholds recommended by the China CDC, and these
recommended thresholds have recognized limitations. Our study therefore seeks to
explore an operational method to select the proper early warning threshold
according to the epidemic features of local infectious diseases. METHODS: The
data used in this study were extracted from the web-based Nationwide Notifiable
Infectious Diseases Reporting Information System (NIDRIS), and data for
infectious disease cases were organized by calendar week (1-52) and year
(2009-2015) in Excel format; Px was calculated using a percentile-based moving
window (moving window [5 week*5 year], x), where x represents one of 12 centiles
(0.40, 0.45, 0.50?.0.95). Outbreak signals for the 12 Px were calculated using
the moving percentile method (MPM) based on data from the CIDARS. When the
outbreak signals generated by the 'mean + 2SD' gold standard were in line with a
Px generated outbreak signal for each week during the year of 2014, this Px was
then defined as the proper threshold for the infectious disease. Finally, the
performance of new selected thresholds for each infectious disease was evaluated
by simulated outbreak signals based on 2015 data. RESULTS: Six infectious
diseases were selected in this study (chickenpox, mumps, hand foot and mouth
diseases (HFMD), scarlet fever, influenza and rubella). Proper thresholds for
chickenpox (P75), mumps (P80), influenza (P75), rubella (P45), HFMD (P75), and
scarlet fever (P80) were identified. The selected proper thresholds for these 6
infectious diseases could detect almost all simulated outbreaks within a shorter
time period compared to thresholds recommended by the China CDC. CONCLUSIONS: It
is beneficial to select the proper early warning threshold to detect infectious
disease aberrations based on characteristics and epidemic features of local
diseases in the CIDARS.
