[Draft] GP Connect (Patient Facing) Appointment Management

Note: This version is in draft and is currently being migrated from the Appointment Management specification.

How to cancel an appointment

How to cancel an appointment

Use case

This API is used to cancel a patient's future appointment, obtained through either How to retrieve a patient's appointments or How to read an appointment.

Any future appointment, irrespective of booking organisation or whether the appointment was booked via this API, can be cancelled by a consuming organisation participating with the appointment hosting organisation in a GP Connect deployment.

The typical flow to cancel an appointment is:

Search by NHS Number for, or otherwise obtain, a Patient resource.
Search for Appointment resources for the Patient resource.
Choose an Appointment resource and cancel it by amending the status to cancelled.

Note: This API is aimed at the administration of a patient's appointments. As a result of information governance (IG) requirements, the book appointment capability has been restricted to future appointments. See Design principles.

Security

GP Connect utilises a JSON Web Tokens (JWT) to transmit clinical audit and provenance detail.

Prerequisites

Consumer

The consumer system:

SHALL have previously resolved the organisation's FHIR® endpoint base URL through the endpoint lookup process
SHALL have received the patient's NHS number from the client app
SHALL have previously found the appointment ID using How to retrieve a patient's appointments
SHALL have populated or otherwise retrieved a patient resource

Consumer display requirements

Consumer systems SHALL support the following fields in order to provide the full context of the appointment in the current IM1 standard:

confirmation of cancellation of appointment outcome (success, failure, and so on)

API usage

The consumer system SHALL only use the cancel appointment capability to cancel future appointments where appointment start dateTime is after the current date and time. If the appointment start date is in the past the provider SHALL return an error.

Request operation

FHIR relative request

PUT /Appointment/[id]

FHIR absolute request

PUT https://[proxy_server]/https://[provider_server]/[fhir_base]/Appointment/[id]

Request headers

Consumers SHALL include the following additional HTTP request headers:

| If-Match | The Appointment's current ETag, e.g. W/"23" |

Payload request body

The request payload is a profiled version of the standard FHIR® Appointment resource. See All Assets for more details.

Consumer systems:

SHALL send an Appointment resource that conforms to the Profile: GPConnect-Appointment-1 profile.
SHALL include the URI of the GPConnect-Appointment-1 profile StructureDefinition in the Appointment.meta.profile element of the appointment resource

Note: It is recommended that consumers read the appointment they wish to cancel (via Read an appointment or Retrieve a patient's appointments), then update the fields allowed below in place. Attempting to recreate the Appointment resource from local transformed data formats/structures is not advised, and may result in the provider system rejecting the amendment due to an unintended change or missing field.

Only the following data elements can be modified when performing an appointment cancellation:

the appointment status SHALL be updated to "cancelled"
the appointment cancellation-reason extension SHALL be included with the cancellation reason details

Note: If any content other than the appointment cancellation reason or appointment status is updated the server SHALL reject the amendment and return an error.

Note: GP Connect does not impose a character limit on the cancellation reason extension within the cancellation request, but due to differences in the provider system the cancellation reason may be truncated when stored in the provider system due to character limits.

Request response

Response headers

Provider systems are not expected to add any specific headers beyond that described in the HTTP and FHIR® standards.

Payload response body

Provider systems:

SHALL return a 200 OK HTTP status code on successful execution of the operation
SHALL return an Appointment resource that conforms to the Profile: GPConnect-Appointment-1 profile
SHALL include the URI of the GPConnect-Appointment-1 profile StructureDefinition in the Appointment.meta.profile element of the returned appointment resource
SHALL include the versionId of the current version of each appointment resource
SHALL have updated the appointment status to "cancelled"
SHALL have updated the appointment cancellation-reason in line with any details supplied in the request
SHALL populate serviceType.text with the practice-defined slot type description, and where available serviceCategory.text with a practice-defined schedule type description (may be called session name or rota type)
MAY populate Appointment.reason.text with the free text reason for the appointment, if it is populated
SHALL meet FHIR resource guidance populating all fields where data is available, excluding those listed below
SHALL NOT populate the following fields:
- specialty
- reason

Note: A status response `200` OK implies that the state of any resources affected by the appointment cancellation (for example, the associated `Slot`) subsequently reflects the cancellation (for example, `Appointment.status`, `Slot.status` are updated in line with any internal integrity constraints).

Error handling

The provider system:

SHALL return a Profile: GPConnect-OperationOutcome-1 resource that provides additional details when one or more data fields are corrupt or a specific business rule/constraint is breached
SHALL return an error if any appointment details other than the appointment status and cancellation-reason fields are attempted to be updated
SHALL return an error if the appointment being cancelled is in the past (the appointment start dateTime is before the current date and time)
SHALL return an error if the version identifier in the If-Match header does not match the appointment's current version identifier see General API Guidance

See Error Handling for details of error codes.

Examples

Cancel an appointment

Request

The Appointment resource is submitted with the status field set to cancelled and a FHIR extension carrying the reason for cancellation.
