GP2GP - HL7 V3

Transfer patients' electronic health records, securely and quickly, between their old and new practices when they change GPs.

Overview

Use this integration to transfer patients' electronic health records between old and new practices when they change GPs.

You can:

  • include large records and those with many attachments
  • reduce paper printing when patients leave a practice
  • integrate (file) the electronic health record for returning patients
  • log issues easily with easy-to-understand and more informative error messages
  • monitor in real time the processes to track issues and performance

For more details, see GP2GP.


Who can use this

This integration can only be used where there is a legal basis to do so. Make sure you have a valid use case before you go too far with your development.

You must do this before you can go live (see ‘Onboarding’ below). 



Status

This integration is in production.


Service level

This integration is a silver service, meaning it is operational 24 hours a day, 365 days a year but only supported during business hours (8am to 6pm), Monday to Friday excluding bank holidays.

For more details, see service levels.


Technology

This integration is an HL7 V3 integration.

For more details, see HL7 V3.

Message Handling System (MHS) adaptor

To remove the complexity of building your own Message Handling System, we offer a pre-assured, client side MHS adaptor that you can integrate into your own infrastructure.

It makes it easier to connect to the NHS Spine and perform business operations by exposing a RESTful API that conforms to the HL7 V3 standard

 

GP2GP Sending Adaptor (In Development)

If you are building a system that receives EHR (Electronic Health Record) requests and responds with HL7 V3 EHR messages, you can use our GP2GP Sending Adaptor to handle the requests and map FHIR records to the desired HL7 V3 output. This is also compatible with the Message Handling System (MHS).

 

GP2GP Receiving Adaptor (In Development)

If you are building a system that creates EHR requests and needs to convert the responses to FHIR from HL7 V3, you can use our GP2GP Receiving Adaptor to the generate the requests and convert the response to the desired FHIR output. This is also compatible with the Message Handling System (MHS).


Network access

You need a Health and Social Care Network (HSCN) connection to use this integration.

For more details, see Network access for APIs.


Security and authorisation

Authentication

This integration is user-restricted, meaning an end user must be present and authenticated to use it.

The end user must be:

  • a healthcare worker
  • strongly authenticated using an NHS smartcard

For more details see user-restricted APIs.

Authorisation

For some activities, the end user must be authorised to perform that activity.

The integration itself does not perform any authorisation checks. Rather, the calling system is expected to perform them. The authorisation rules are specified in our national Role Based Access Control (RBAC) database.

For more details see our national Role Based Access Control (RBAC) database on the registration authorities page.


Testing

You can test this integration using our Path to Live environments.


Onboarding

You must get your software onboarded before it can go live.

Contact us before onboarding with this integration. It uses the Common Assurance Process (CAP) which is tailored for each NHS service.


Interactions

For a full list of interactions for this integration, see the GP2GP domain in the Spine Message Implementation Manual (MIM).

For details on the general structure of the interactions, see HL7 V3.


Additional guidance

For more details about requirements and specifications of the record transfer mechanism, see the GP2GP section in the GP IT Futures Capabilities and Standards guidance.
