Total response time in EMS is defined as the interval from which event to which event?

• A. On-scene time from arrival to departure.
• B. Time from hospital arrival to patient contact.
• C. Dispatch to hospital arrival.
• D. Dispatch to first patient contact.

Answer: (D)

Total response time measures how quickly EMS begins interacting with a patient after a call is received. It is defined as the interval from the moment the call is dispatched to the first patient contact by responders. This captures the entire interval from activation to when the provider starts the patient assessment or interaction. The other options describe different parts of the process: on-scene time is the period from arrival on scene to departure, which occurs after you’ve reached the patient. Time from hospital arrival to patient contact would occur after transport, not during the initial response. Dispatch to hospital arrival spans from the call being dispatched all the way to reaching the hospital, including transport and handoff, which is broader than the initial response.
