Booking and Referral Standard

The Booking and Referral Standard (BaRS) is an interoperability standard that helps a service to send or receive booking and referral information to or from another care provider for the purpose of a patient's ongoing care.

An interoperability standard describes a set of rules that govern the format, language and delivery for transferring data or information from any healthcare system to another. 

Adopting BaRS for sending and receiving booking and referral requests allows healthcare professionals in all settings to receive relevant information into existing healthcare IT systems quickly, safely and in a format that is useful to meet patient care needs.

Who this service is for

The standard will be used by healthcare IT system suppliers to support healthcare services looking for a digital solution to improve their booking and referral process. The standard is applicable to organisations developing their solutions to implement BaRS.

Systems developing BaRS need to be assured prior to implementation. 


Benefits of BaRS

Implementing BaRS has a positive impact on the following user groups:






How this service works

There are three main layers that make up the framework in BaRS.



Documentation for BaRS

The documentation for BaRS is separated into three groups or products: 

1. Core 1.4.0 is the foundation for BaRS and contains all elements required regardless of the workflows BaRS is being used to support.

2. BaRS Applications use the standard to support a particular patient journey.

3. BaRS Pre-Releases are the same as BaRS Applications but apply to applications that are in a pre-release state and therefore not available until private or public beta is complete.


How to access this service

National usage policy

The Data Alliance Partnership Board (DAPB) has approved BaRS as an information standard. A corresponding Information Standards Notice, reference DAPB4060 has been issued to support adoption and use of the standard.

All healthcare IT system suppliers delivering systems to healthcare providers in applicable care settings must work with their customers to determine any necessary changes.


Status, service level and current usage

This service is live and has been since April 2023.

You can view the supplier status of each organisation engaged with the booking and referral standard and their status.

The central BaRS routing proxy is a gold service which means it is supported 24 hours a day, 365 days a year.


Information standard notice (ISN) conformance dates

There is no single conformance date for BaRS across NHS care settings as the scope of the standard will expand over time. NHS England will identify appropriate conformance dates as BaRS is developed for each new patient journey.
