In EMS terminology, what term refers to the symptom or problem reported by the patient as the reason for the call?

• A. Chief complaint
• B. Assessment
• C. Diagnosis
• D. History

Answer: (A)

The main concept is that EMS uses chief complaint to capture the reason the patient sought help—the symptom or problem the patient reports in their own words as why the call was made. This guides how responders triage, prioritize, and begin care. For example, if a patient says, “I have chest pain,” that phrase is the chief complaint and sets the initial focus, even before a full assessment is done.

This term is not a diagnosis, which is the clinician’s final determination after evaluation and tests. It’s also not the patient’s history, which covers past illnesses, medications, allergies, and events leading up to the current problem. And it’s not the formal assessment, which is the provider’s findings from exam and tests. The chief complaint is simply the reason for the call, described by the patient.
