 What is the COSD?

The national standard for reporting cancer in the NHS in England since January 2013. Please see the Background to the COSD for more information. 

Documentation for the COSD Information Standard (SCII1521 Amd 17/2014) including the Specification, Change Notice and Implementation Guide is available on the HSCIC website. The latest version of the COSD Dataset and Schema, guidance and supporting documentation are available via the Downloads webpage.

COSD changes 2015

In order to ensure that the COSD remains up to date and fit for purpose we need to identify and submit changes on a regular basis, usually annually. The official notification for 2015 changes is now available on the HSCIC website, including the revised Specification and Implementation guide.  All other documentation can be downloaded from the Downloads page.  This now includes the final pathology specific schema to support structured XML submissions from January 2016.

Please note that there is one change to the dataset from the prepublication version. This is to reinstate UR15300 - STAGE GROUPING (TESTICULAR) in the Urology dataset as this was deleted in error.   

Submission Schedule

The schedule below gives the deadline for Providers to submit the COSD data for each calendar month of diagnosis/treatment. (PAS feeds have a later deadline)  Feedback reports for the data submitted are available through the NCRS COSD Conformance Monitoring Feedback Portal.

A revised Conformance Framework has been published to align with v6.0. The Framework provides an outline of the conformance and quality checking reports which are provided following submission, processes for dealing with any problems in submission and the escalation process if these issues cannot be resolved locally. This document should be reviewed in conjunction with the Data Transfer Partnership Agreement which Providers have completed detailing key contacts and details of the data they submit to the NCRS. The  Conformance Framework is available from the the Downloads webpage.
