Commissioning Data Sets

Commissioning Data Sets (CDS) enable national reporting on NHS funded or provided secondary care.

What is the distinction between provided care and funded care?

Provided care is care which is directly provided by the NHS. Funded care is paid for by the NHS but provided by another organisation.

The Commissioning Data Sets do not include data about private treatment where there is no NHS involvement.

Status

The Commissioning Data Sets (CDS) are maintained and developed by NHS Digital, in accordance with the needs of the NHS and the Department of Health and Social Care.


Background

CDS form the basis of data on activity carried out by NHS trusts reported centrally for monitoring and payment purposes. They support national reporting through Hospital Episode Statistics (HES), the current Healthcare Resource Group (HRG) version 4 for calculation of payment to trusts and monitoring of other initiatives including Referral to Treatment (RTT).

Changes to CDS, as well as changes to some data items included within CDS such as Treatment Function Codes and Main Specialty Codes, are reviewed and approved by the Data Alliance Partnership Board (DAPB) and therefore require evidence that they can be implemented in services and are interoperable with NHS systems.


Commissioning Data Sets (CDS) v6.3

An update to CDS, v6.3 has recently been approved by the Data Alliance Partnership Sub Board (DAPSB) on behalf of the Data Alliance Partnership Board (DAPB).

The CDS v6.3 changes are designed to update CDS in line with current clinical and data recording practices, as well as to support recent policy initiatives and enable conformance with other information standards and legislation introduced since CDS v6.2 went live.

The CDS v6.3 update enables SNOMED CT codes to be submitted, including those authored in support of the COVID-19 pandemic, and introduces some minor updates to data items to conform with recent NHS Data Model and Dictionary changes.

CDS v6.3 will go live for data submissions in April 2022, with a 12-month transition period for all submitters to start sending CDS v6.3 data by April 2023.

The updated Information Standards Notice DAPB0092 Amd 64/2020, was published on 15 June 2021 and is available along with supporting documentation. 


CDS v6.3 additional supporting documents

CDS v6.3 Enhanced Technical Output Specification

A specification for the output data set required of providers which defines each data item within the data set. This document splits the data set into CDS types, each containing data groups, items and national codes.  

This is the Enhanced TOS, which includes the business rules that will be applied by the XML submission schema. The schema itself will be available from the TRUD webpage in September 2021.

CDS v6.3 Detailed Change Specification

The Detailed Change Specification shows the changes made to the CDS v6.2 specification in comparison to CDS v6.3. Changes to data item names, formats, national codes and their descriptions, mandation levels, repeats and business rules are marked for individual CDS types.


CDS v6.3 overview webinars

In November 2020 NHS Digital ran three webinars to explain and discuss the requirements that have been gathered for the forthcoming CDS v6.3 uplift. View a recording of the webinar, transcript and presentation slides.  

If you have any questions about the CDS v6.3 update, please contact us by emailing enquiries@nhsdigital.nhs.uk


Change process

Requests for changes to the CDS should be submitted via email to enquiries@nhsdigital.nhs.uk

Change requests are logged and considered for prioritisation. For changes to be considered, they must have evidence of supporting a business requirement and have sponsorship from the Department of Health.

Changes to the CDS impact on a wide range of organisations and service areas including:

  • NHS trusts
  • Patient Administration Systems (PAS) suppliers
  • Secondary Uses Service
  • NHS Data Dictionary
  • Payment by Results

The changes need to be assured and approved so that they can be mandated via the issuing of an updated Information Standards Notice and appropriate notice can be given of the implementation date.
