Syndromic Surveillance

The United States Centers for Disease Control and Prevention (CDC) describes syndromic surveillance (SyS) as the practice of using data and statistical tools to detect, monitor, and characterize unusual activity for further public health investigation or response. Syndromic data may include information on patients seeking treatment at emergency, urgent care, ambulatory care, and inpatient healthcare settings. Some jurisdictions may also utilize information from other sources like poison centers, pharmacies, schools, and social media.

Since data collection occurs prior to a physician diagnosis or laboratory result, a symptom complex or syndrome is determined using information available for each encounter and complex computer algorithms. In other words, syndrome classifications are pre-diagnostic. Public health monitors syndromic data in near real-time because it may present an emergent picture of community-level health events. Pre-diagnostic recognition of events, disease, and outbreaks can lead to early public health intervention.
