Data Sources and Systems


EpiCenter:  De-identified chief complaint data from participating hospitals is automatically collected and categorized into syndrome categories (for example: respiratory, gastrointestinal, neurologic) in real time. If an unusual pattern is detected in EpiCenter, the system automatically notifies the Ohio Department of Health and the affected local health departments. Epidemiologists then determine if the unusual pattern has public health significance and will follow up with control measures if necessary. Approximately 94 percent of Ohio’s emergency department visits are captured by this system.


National Retail Data Monitor (NRDM):  Over-the-counter drug sales information is collected from 1,451 Ohio pharmacies and grocery stores and categorized into product groupings (for example: pediatric cough syrup, adult anti-fever medications, thermometer sales). NRDM data are monitored by state and local epidemiologists for patterns suggesting a health event.


Influenza Sentinel Provider Surveillance Network: The number of patients treated for influenza-like-illness (ILI) are reported by age group via more than 70 health care providers throughout Ohio. Participating providers also submit laboratory specimens to ODH lab for subtyping. Information from this system helps public health determine which influenza strains are currently circulating.
