Event Notifications
| Type | Use Case | Suggested Standards |
|---|---|---|
| Resource | Admission and Discharge Notifications, Observation alerts (high blood pressure, etc), Appointments, Patient demographics updates | FHIR Workflow |
The earliest form of Event Notification was a key focus of early HL7 standards and is normally referred to as the HL7 v2 Admission, Discharge and Transfers (ADT) standard. This covered a series of use cases, including:
- patient was registered.
- patient demographics have been updated.
- patient has arrived or attended outpatient clinic.
- patient has been admitted to, arrived at or discharged from hospital.
- patient has an appointment or is scheduled to be admitted to hospital.
- Significant clinical event (e.g. high blood pressure reading)
Description
Admission, Discharge and Transfers: The use of HL7 v2 in the acute sector is quite widespread and so it is not believed that HL7 FHIR will replace HL7 v2 in this care setting in the near future. The
HSCIC ITK - HL7v2 Interoperability Message Specification and
HSCIC ITK - HL7v2 Interoperability Message Specification Reference Tables
is the suggested standard to use with HL7 v2 ADT. At present no mapping exists between this and UKCore, however it is believed the two standards are in most cases consistent.
This interaction method differs from Event Message in that it is not intended to transfer/exchange records. It is purely a notification system and it typically used to complement Query Patient Care Data, which the recipient practitioner or system can use to view details on the event if they wish. Events Notifications in FHIR will generally use RESTful API
