Every time an emergency medical service (EMS) incident is reported, all incident information provided is captured in the city's Computer Aided Dispatch (CAD) system. This data helps emergency incident dispatchers determine the medical category, severity level of the emergency, and appropriate response level. 
Once first responders are dispatched to provide medical aid, they update the incident disposition (on-scene status) in CAD to reflect what they find on-scene. The data displayed in the dashboard is only for the Cincinnati Fire Department's (CFD) responses to reported emergency medical incidents, and does not include patient information or medical outcome data (Fire & Rescue Incident Response dashboard is available HEREHeroin Overdose Dashboard, which are a subset of this data, can be found HERE).
