2:3.116.4.1 Hold Appointment Request

This transaction uses the $hold operation as defined in the Operation Definition.

2:3.116.4.1.1 Trigger Events

This is an optional transaction in the ITI Scheduling Profile. and in cases where the requester needs additional information, or needs to perform additional steps before an appointment is booked, the Scheduling client can request a hold for a specific potential appointment that is the result of a Find Potential Appointments [ITI-115] transaction.

2:3.116.4.1.2 Message Semantics

The Hold Appointment request is defined as a FHIR Operation. Please see the corresponding Operation Definition.

2:3.116.4.1.3 Expected Actions

The Scheduling Server is expected to hold the necessary time slots and resources for the potential appointment to take place at the given time and for the given duration.

Note that it is possible that between the time the Find Potential Appointments [ITI-115] response was received, and the time the Hold Appointment [ITI-116] request is issued, the requested appointment is no longer available. In such case, the server SHALL respond with an OperationOutcome that describes the issue.

The response to the $hold operation is an Appointment resource or an OperationOutcome resource. The Appointment resource SHALL have the Appointment.status set to pending.

The response is an ITI Scheduling Appointment Bundle. A successful $hold operation SHALL return a single Appointment resource within the bundle, and MAY have an additional OperationOutcome resource with supplemental information. An unsuccessful $hold operation SHALL return only an OperationOutcome resource describing the problem with satisfying the operation.

2:3.116.4.2.3 Expected Actions
