Which item is a component of the EMS minimum data set?

• A. Time of arrival on scene
• B. Phone number of caller
• C. Weather conditions at the scene
• D. Insurance provider

Answer: (A)

The EMS minimum data set includes standard time stamps that document key moments in the incident, such as when EMS arrives on scene. This arrival time is included because it directly supports calculating response times and monitoring performance for quality improvement and accountability. The other data points—weather conditions at the scene, the caller’s phone number, and the patient’s insurance provider—are not standard elements of the EMS minimum data set. They may appear in other records, but they aren’t required for the essential data used to track response and on-scene care.
