API

• {Base URL} (Dev1) = https://api.dev1.ers.ncrs.nhs.uk/ers-api
• = Desired Value Set from eRS-Specialty-ValueSet-1

Description

This read-only API lets a user access a pre-populated list of reference data. The NHS e-Referral Service uses these lists throughout. For example, a list of specialities. They support data accuracy and effective re-use. It retrieves a specific Value Set (Reference Dataset) by ID.

Reference Data

Reference data is classified into 2 types:

Static lists

These are documented on the FHIR server and can be looked up “manually” and stored once and for all in the database.

• Values and associated business logic, such as adding/removing options (e.g. Priority, Request Type, Commissioning Type) - this means creating new business flows in the application, which means an upgrade is probably needed
• Standard FHIR lists

Dynamic lists

These are “gettable” from e-RS; third parties should handle them as dynamic data, i.e. adding/removing values should not require a software upgrade.

• The only dynamic list we have so far is Specialty
• The next forthcoming dynamic list is Clinic Type
• In future we will be adding Rebooking Reasons/Cancellation Reasons and other dynamics lists

Input

Currently applicable values for the {valueSetId}:

Header

Provide ASID of the end-point system and equivalent Session Key generated for the SSO Token-ID.

Example

XAPI_ASID:200000000220
Content-Type:application/json+fhir
HTTP_X_SESSION_KEY:pro-xapi-session_5a399946-23c5-4543-8c4f-7eca38732a58

Output

A Value Set Resource profiled specifically for the given valueSetId. This will include the requested coding system with its available codes. The response code 200 (OK) is returned.
