Additional use-cases are expected to be supported in 2023.
The following section describes error scenarios and associated error codes for this capability.
where the received message does not conform to the requirements stated for ITK3 header, or for the payload, the message MUST be considered invalid
where a received message is invalid, an ITK3 Response MUST be generated with the corresponding Negative ITK3 Response Code, which indicates the nature of the error, and the message MUST NOT be accepted for downstream processing
The error context and description MUST be provided in the
OperationOutcome.diagnostic element to enable the sender to correctly identify the error which has been found in their sent message
See Profile: ITK-Response-OperationOutcome-1 for more information on how to populate this FHIR resource.
MESH endpoint lookup
The following table describes error codes returned from the MESH server as a result of issues encountered using the facility to route a message automatically to the registered practice.
The following errors, when encountered, MUST be handled gracefully by the message sending system:
|Status Code||MESH Error Code||Description|
|EPL-150||ERROR_TOO_MANY_MAILBOX_MATCHES||Multiple mailboxes matches|
|EPL-151||ERROR_NO_MAILBOX_MATCHES||No mailbox matched|
|EPL-152||ERROR_INVALID_NHSNUMBER||Invalid NHS Number|
|EPL-153||ERROR_NHSNUMBER_NOT_FOUND||NHS Number not found|
|EPL-154||ERROR_NO_DEMOGRAPHICS_MATCH||NHS Number supplied does not match the demographics|
MESH will generate these errors in the form of error reports which will be placed in the sender’s mailbox to await collection and processing by the sending organisation.
Note: When using the MESH API to send a message, errors encountered when using the automated registered practice routing will not be returned in the API response header or payload, but via a MESH error report .CTL file placed in the sending organisation MESH mailbox.
For example, where an invalid NHS Number has been supplied in the
Mex_To HTTP header, an error report .CTL file will be returned with a
<StatusRecord> section, which provides error details as follows:
<StatusRecord> <DateTime>20170926135509</DateTime> <Event>SEND</Event> <Status>ERROR</Status> <StatusCode>EPL-152</StatusCode> <Description>Invalid NHS Number</Description> </StatusRecord>
- where a Consultation Report is not successfully received/managed by the message receiver, the sender system MUST inform an appropriate person
- where either the infrastructure or business acknowledgements, or both, are not received for a Consultation Report, the sender system MUST inform an appropriate person
