As syndromic surveillance systems continue to grow, new opportunities have arisen to utilize the data in new or alternative ways for which the system was not initially designed. For example, in many jurisdictions syndromic surveillance has recently become population-based, with 100% coverage of targeted emergency department encounters. This makes the data more valuable for real- time evaluation of public health and prevention programs. There has also been increasing pressure to make more data publicly available – to the media, academic partners, and the general public. 

In October 2015, the Centers for Disease Control and Prevention (CDC) released health advisory #384 to inform people about increases in fentanyl fatalities. Florida’s statewide syndromic surveillance system, Electronic Surveillance System for the Early Notification of Community-based Epidemics (ESSENCE-FL), captures electronic death record data in near real time which allows for the monitoring of mortality trends across the state.

Syndromic surveillance ED data has historically shown the highest number of visits on Mondays, with decreasing volumes throughout the week. Previous studies have shown that increased negative health outcomes have occurred on Mondays. A study in the European Journal of Epidemiology provided evidence that suggests a higher incidence of cardiovascular events on Mondays compared to other days of the week.

Objective

Syndromic surveillance has historically been used to track infectious disease, but in recent years, many jurisdictions have utilized the systems to conduct all hazards surveillance and provide situational awareness with respect to previously identified issues. Flakka is a synthetic drug (class: cathinones) that recently has been featured in the media. Flakka is a stimulant that causes delusions, aggression, erratic behavior, a racing heart and sometimes death. Two specific counties (one in Florida and one in Kentucky) have been at the center of this emerging epidemic.
