North Carolina Disease Event Tracking and Epidemiologic Collection Tool
The North Carolina Disease Event Tracking and Epidemiologic Collection Tool (NC DETECT) is North Carolina's statewide syndromic surveillance system. NC DETECT was created by the North Carolina Division of Public Health (NC DPH) in 2004 in collaboration with the Carolina Center for Health Informatics (CCHI) in the UNC Department of Emergency Medicine to address the need for early event detection and timely public health surveillance in North Carolina using a variety of secondary data sources. Authorized users are currently able to view data from emergency departments, the Carolinas Poison Center, and the Pre-hospital Medical Information System (PreMIS), as well as pilot data from select urgent care centers.
NC DETECT is designed, developed and maintained by CCHI staff with funding by the NC DPH. New functionality is added regularly based on end user feedback.
NC DETECT data are included in the NC Division of Public Health Weekly Influenza Summary available at http://www.flu.nc.gov/data/
The proportion of ED visits meeting the NC DETECT influenza-like illness syndrome definition is monitored throughout the year and compared to data obtained from the Influenza-like Illness Surveillance Network (ILINet). In past years, data from the two systems have shown similar trends. The higher proportion of ILI seen in NC DETECT compared to ILINet reflects differences in the case definitions and patient populations rather than a difference in the sensitivity of these surveillance systems.
