Amend an appointment for a patient at an organisation

Use case

This API is used to amend the description or comment fields of a patient’s future appointment, obtained via either the Retrieve a patient’s appointments, or Read an appointment APIs. Any appointment irrespective of booking organisation can be amended by a consuming organisation participating with the appointment hosting organisation in a GP Connect deployment.

The typical flow to amend an appointment is:

  1. Search by NHS number for, or otherwise obtain, a Patient resource.
  2. Search for Appointment resources for the Patient resource.
  3. Choose an Appointment resource and update description and/or comment fields.

Amending a cancelled appointment is NOT supported.

Security

  • GP Connect utilises TLS Mutual Authentication for system level authorization
  • GP Connect utilises a JSON Web Tokens (JWT) to transmit clinical audit and provenance details

Prerequisites

Consumer

The consumer system:

API usage

The consumer system SHALL only use the amend appointment capability to amend:

  • description or comment fields. Providers SHALL return an error when any other field is amended.
  • future appointments where appointment start date/time is after the current date/time. If the appointment start date/time is in the past the provider SHALL return an error.
  • appointments that have not been cancelled. Providers SHALL return an error where an amendment to a cancelled appointment is received.

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:

Header Value
Ssp-TraceID Consumer’s TraceID (i.e. GUID/UUID)
Ssp-From Consumer’s ASID
Ssp-To Provider’s ASID
Ssp-InteractionID urn:nhs:names:services:gpconnect:fhir:rest:update:appointment-1
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 FHIR resources page for more detail.

Consumer systems:

  • SHALL send an Appointment resource that conforms to the 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.
  • SHALL NOT amend an appointment with a status of cancelled

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

  • description containing a brief description of the appointment.
    • Consumers SHALL impose a character limit of 100 characters for this element.
    • This element SHALL only contain limited information to support the appointment and SHALL NOT be used for “transfer of care” clinical information.
  • comment containing ‘patient specific notes’ and any additional comments relating to the appointment.
    • Consumers SHALL impose a character limit of 500 characters for this element.
    • This element SHALL only contain limited information to support the appointment and SHALL NOT be used for “transfer of care” clinical information.

Provider handling of description and comment

When receiving description and comment fields in the provider system:

  • Providers systems SHALL store information received in description and comment fields, supporting the character limit lengths shown above
  • Providers systems SHALL NOT truncate information received in description or comment fields
  • Providers SHALL return description and comment fields to the consumer in the response payload, as stored
  • Where a consumer sends information longer than character limits supported, an error SHALL be returned to the consumer
  • Where there are not two suitable appointment text fields in a provider system, providers MAY concatenate description and comment (with suitable delimiters) in order to store in a single field, such that data is not lost

Example request body

On the wire, a JSON serialised request would look something like the following:

Error handling

The provider system:

  • SHALL return a GPConnect-OperationOutcome-1 resource that provides additional detail when one or more request fields are corrupt or a specific business rule/constraint is breached.
  • SHALL return an error where:
    • any appointment details other than the appointment comment or description are amended. The appointment resource should be considered invalid and the provider system should return a 422 error with error code INVALID_RESOURCE.
    • the appointment being amended is in the past (the appointment start dateTime is before the current date and time).
    • the appointment has been cancelled. Provider systems should return a 422 error with error code INVALID_RESOURCE.
    • the version identifier in the If-Match header does not match the Appointment’s current version identifier. See Managing resource contention.
    • the description or comment fields contain more characters than can be stored in the provider system

Refer to Development - FHIR API guidance - error handling for details of error codes.

var appointment = client.Read<Appointment>("Appointment/9");
// Update The Comment For The Appointment
appointment.comment = "Free text updated comment.";

Java

// Read appointment to be updated

IGenericClient client = ctx.newRestfulGenericClient("http://gpconnect.aprovider.nhs.net/GP001/STU3/1");
Appointment appointment = client.read().resource(Appointment.class).withId("9").execute();

// Amend appointment comment

// Update appointment
MethodOutcome response = client.update()
	.resource(appointment)
	.prefer(PreferReturnEnum.REPRESENTATION)
	.preferResponseType(Appointment.class)
