If the service event continues past midnight, then the date on which the service commenced should be recorded.

The Non-admitted patient (NAP) data set is intended to capture instances of healthcare provision from the point of view of the patient. This may be for assessment, examination, consultation, treatment and/or education.

One service event is recorded for each interaction, regardless of the number of healthcare providers present.

Events broken in time:

The period of interaction can be broken but still regarded as one service event if it was intended to be unbroken in time. This covers those circumstances in which treatment during a service event is temporarily interrupted for unexpected reasons, for example, a healthcare provider is called to assess another patient who requires more urgent care. Where a healthcare provider is unable to complete the interaction, it is considered to be a service event only if the definition of service event (above) is met.


Service events can occur in an outpatient clinic or other setting. 


Service events delivered via Information and Communication Technology (ICT) (including but not limited to telephone and where the patient is participating via a video link) are included if:

  • they are a substitute for a face-to-face service event, and
  • the definition of a service event (above) is met.

Accompanied patients:

If a patient is accompanied by a carer/relative, or the carer/relative acts on behalf of the patient with or without the patient present (e.g. the mother of a two-year-old patient, or the carer for an incapacitated patient), only the patient’s service event is recorded unless the carer/relative interaction meets the definition of a service event (above).

Note: carer refers to an informal carer only.

Service events delivered in groups:

Care provided to two or more patients by the same service provider(s) at the same time can also be referred to as a group session.

One service event is recorded for each patient who attends a group session regardless of the number of healthcare providers present, where the definition of a service event (above) is met.

Service requests:

A service event is the result of a service request (including formal referral and self-referral or attendance at a walk-in clinic).

Activities which do not meet the definition of a service event include:

  • Work-related services provided in clinics for staff.
  • Non-attendances for a booked outpatient or booked outpatient services that did not go ahead.
