Drug overdoses and related deaths have been escalating nationally since 1970. In Virginia, the rate of drug overdose deaths increased 36% from 5.0 to 6.8 deaths per 100,000 population between 1999 and 2010. While initiated for bioterrorism event detection, syndromic surveillance has shown utility when extended to other health issues. ED visits may complement information from Overdose Deaths investigated by the Office of the Chief Medical Examiner (OCME) in describing drug overdose trends. Due to its real-time nature, syndromic surveillance data could act as an early indicator for emerging drug problems in the community, serving as an alert to public health.
Objective
Determine if syndromic surveillance data can be used to provide a real-time picture of the drug using population by analyzing trends of emergency department (ED) visits for unintentional drug overdose (Overdose Visits) in conjunction with unintentional deaths that prescription or illicit opiates contributed to or caused (Overdose Deaths).
