No patient found

No patient found is an EMS outcome indicating that the responding crew did not locate a patient in the circumstances documented. It describes what the crew found during its response. It does not establish that the original caller was mistaken, that no medical problem existed, or that the call was deliberately false.

Understanding the recorded outcome

The dispatch record and the crew's final record describe different stages. Dispatch may begin with an account of someone needing help. The completed response may establish only that no patient was located when the crew arrived.

NEMSIS distinguishes “No Patient Found” from “No Patient Contact” and cancellation before arrival. Its no-patient example also separates the unit's outcome from fields about treatment and transport. NEMSIS no-patient flowchart.

That distinction matters because a public label often omits the sequence of events. The outcome should be read alongside any available location, cancellation, or disposition explanation, without assuming that missing details have a particular meaning.

Example

Hypothetical: A caller reports a person who appears to need assistance near a transit stop. A crew reaches the reported location, searches as documented in its report, and records that no patient was found.

The public outcome describes that response. It does not reveal where the person went, whether another service helped, or whether the caller's observation was accurate. A summary stating “crew did not locate a patient” is supported by the label. A statement that “the emergency was fake” is not.

Common confusion

A refusal requires a recorded decision about offered services. No patient found does not document such a decision. “No treatment” is also broader: it may describe a patient who was evaluated without receiving treatment, which is a different encounter.

Cancellation before arrival says that the response ended before the unit reached the scene. It should not be used as a substitute for a documented search or on-scene outcome. Multiple responding agencies can also have different records from the same event.

Counting these responses

Decide whether the report counts unit outcomes or unique incidents. Two units can each have a no-patient disposition for one call, and merging them requires an incident identifier and a clear rule.

Retain the original category where possible. If a chart groups this outcome with other nontransport responses, explain that the group includes situations with and without patient contact. Nontransport alone cannot show whether care was offered or provided.
