### Scope Overview
This BaRS Application (Referrals from Advice and Guidance to eRS broker, Application 8) supports the following use case(s) ONLY:
-- Advice and Guidance referring into eRS
+* Improved Advice and Guidance to electronic-Referral Service (e-RS)
+* 111Online to electronic-Referral Service (e-RS)
+* NHS.UK to electronic-Referral Service (e-RS)
-The payload and workflow have been designed to support this service. Other {{pagelink:applications, text:BaRS Applications}} offer scope for alternative use cases.

### Functional Scope
-**Directing the referral (without Service Discovery)**
-- Direct to eRS static value
+
+**Service Discovery**
+- Establishing a service, or service shortlist, for onward care is a mandatory step in the workflow
+
+
+**Directing the referral (independent of Service Discovery)**
+- Direct to predefined value representing the broker
**Referral**
- A referral in this Application is a request for care, on behalf of an individual, from a sending service to a broker
- The referral can be sent without having to establish the capacity of the receiving service
- The referral will contain primarily clinical information, indicating the need of the individual and **must** state the anticipated action required by the receiving service (see Task FHIR resource)
- A list of healthcare services which can support the patient/client need are offered to the broker to direct the next step in care
+* Supporting information, other than the assessment, is expected to be included in a referral, if collected, including:
+ * new or existing safeguarding concerns
+ * locally held Special Patient Notes
+ * external information sources used during initial assessment prior to referral
+ * timing information to support the timely delivery of care and reporting
+
**API-M**
- All requests and responses associated with BaRS must occur through the BaRS API Proxy
**Constraints**
- No guidance is provided on the display of referral information beyond the {{pagelink:principles_prerequesites, text:Principles for rendering BaRS Payload}}
-- Consent within BaRS will be for Direct-Care only
+- BaRS currently supports the communication of consent for direct care only
- Certificates for Receiving messages to use nhs.uk domains only
- Receiving endpoints are to be internet facing
- Clincial Constraints exist - See Hazard Log
- No element level 'updates' to requests are supported. A new request must be generated to change information in the referral request
- No digital support to remove or cancel a referral are offered (this would need to be achieved manually)
-- Where an Online Consultation or other self assessment tool is used to refer, the referral must be verified by a human representative of the sending organisation before the request is made
+- The service discovery tool for establishing services for onward care must be the [e-RS Service Search API A010](https://digital.nhs.uk/developer/api-catalogue/e-referral-service-fhir#post-/STU3/HealthcareService/$ers.searchHealthcareServicesForPatient)
### Requirements
-**Directing a referral**
-- The service **must** support a unique identifier which the Sender is configured with to engage in the BaRS referral workflow
+**Service Discovery**
+- Where more than one service is shortlisted, the maximum number of services allowed on a given shortlist is 20.
-**Referral**
-- TBC
-
-**Contacts**
-- A minimum of one contact (patient or third party) with a contact method (phone, email, etc.) of phone **must** be provided in referral requests
-- All contacts **must** have a rank associated with them
-- There **must** be only one contact with a rank of 1
-- All contacts **must** have at least one contact method (phone, email, etc.)
-- All contact methods **must** have a rank
-- There **must** be only one contact method with a rank of 1
-- The contact ranked 1 and the contact method ranked 1 **must** be the primary callback for the request
+**Referral**
+- The referral Receiver **must** accept the referral request regardless of whether the patient is known to the service provider
+- The referral Receiver **must** only accept potential patients who do **have** a national validated identifier e.g. NHS Number
+- The national identifier **must** have a [verification status](https://simplifier.net/hl7fhirukcorer4/valueset-ukcore-nhsnumberverificationstatus) of 'Number present and verified' otherwise, the referral Sender **must not** include it in the request
+- Any new or existing safeguarding concern, recorded as part of the assessment, **must** be included in the referral Sender's request
+- The referral Receiver **must** clearly identify any included safeguarding concern to the end user
+- The referral Receiver **must** accurately represent information made by the Sender to the end user.
+- The referral Sender **must** make available the human readable identifier for the referral, included in the HTTP synchronous response, to the end user
+- Where the referral was not successful, the Receiver **must** send an appropriate response. See {{pagelink:core-failure_scenarios-1.3.1, text:failure scenarios}} for more detail
+- Where the referral was not successful, the Sender **must** present an appropriate message to the end user. See {{pagelink:core-failure_scenarios-1.3.1, text:failure scenarios}} for more detail
+- The referral Sender **must** indicate consent to share (for Direct Care) to the Receiver
+- The referral Sender **must** indicate the urgency (using the agreed codeset) of the request to the Receiver
