The Cancer Outcomes and Services Data Set provides a standard for secondary uses information required to support implementation and monitoring of "Improving Outcomes: a strategy for cancer". It replaced the previous National Cancer Data Set and the Cancer Registration Data Set.
- supports the recommendations made within the "Achieving World Class Cancer Outcomes: A Strategy For England 2015-2020" taskforce report
Additionally the output supports commissioning and service development through provision of relevant information on service delivery and outcomes.
All PATIENTS diagnosed with or receiving cancer treatment in (or funded by the NHS in) England are covered by the standard. This includes adult and paediatric cancer PATIENTS. The standard applies to all Organisations providing Cancer Services within secondary care. It does not apply to general practice Organisations.
The Cancer Outcomes and Services Data Set covers diseases as defined by the United Kingdom and Ireland Association of Cancer Registries (UKIACR) as described in the User Guide at Appendix A and B.
Unless otherwise specified, the term cancer is used throughout the standard and related documents to cover all conditions registerable by the United Kingdom and Ireland Association of Cancer Registries.
While the core and cancer site specific data sets are shown as separate data sets within the NHS Data Model and Dictionary, the COSDS XML Schema integrates each core and cancer site specific set of data elements. Documentation provided on the Technology Reference Data Update Distribution (TRUD) page at: NHS Data Model and Dictionary: DD XML Schemas gives full details of the specification.
For all diagnoses not covered by a cancer site specific data set, only the Core Data Set should be completed. A full list of diagnoses mapped to the appropriate data set is provided in the National Cancer Registration and Analysis Service User Guide.
This replaced the current reporting to the National Cancer Registration and Analysis Service of electronic pathology reports which were then transcribed by the National Cancer Registration and Analysis Service into the Cancer Registration Reports. This also prevented Cancer Service teams, for example, Multidisciplinary Teams, Pathway Co-ordinators, duplicating the work, which had been happening as part of their data collection process.
From April 2017, a separate Pathology XML Schema was introduced, which is a sub-set of the main Cancer Outcomes and Services Data Set.
By creating a sub-set for pathology, this allows the Cancer Service teams to concentrate on collecting and reporting all the other clinical data required for the Cancer Outcomes and Services Data Set and the Pathologists to collect and report the pathology items. This will reduce the burden of data collection for the Cancer Service teams and allow for more accurate pathology reporting to be submitted to the National Cancer Registration and Analysis Service.
There will be no requirement for Pathology Laboratories to double report. Once their Laboratory Information Management Systems (LIMS) are updated to report in the COSDS XML Schema, all other pathology reporting can cease.
