Systemic Anti-Cancer Therapy Data Set Overview


The Systemic Anti-Cancer Therapy Data Set collects clinical management information on PATIENTS undergoing Systemic Anti-Cancer Therapy in (or funded by) the NHS in England.

In the clinical setting its primary use is in prescribing and administering Systemic Anti-Cancer Therapy. The standard also specifies secondary uses information about Systemic Anti-Cancer Therapy which is required to assist in achieving, supporting and monitoring the NHS Operating Framework, specialised commissioning and related policy.

Details of Standard

The Systemic Anti-Cancer Therapy Data Set relates to all cancer PATIENTS, both adult and paediatric, in both admitted PATIENT care and outpatient and community settings, who are receiving Systemic Anti-Cancer Therapy for all solid Tumour and haematological malignancies, including those treated in CLINICAL TRIALS.

The Systemic Anti-Cancer Therapy Data Set covers the period from the Start Date of the Systemic Anti-Cancer Therapy Drug Regimen to the Start Date of the last Systemic Anti-Cancer Therapy Drug Cycle.

Note: PATIENTS may end their treatment with an oral or other component taken at home. Although the dispensing of this will be recorded in the final Systemic Anti-Cancer Therapy Drug Cycle, it is not possible to confirm that the PATIENT has taken the medication.

Data Set Structure and Transmission

Systemic Anti-Cancer Therapy is given over a prolonged period of time, often months or years, comprising repeating and sequential elements.  The PATIENT may attend two or more Health Care Providers during the course of treatment.

In order to track the PATIENT during treatment, the data set must be capable of linking all the elements of care in a consistent and ordered way. In order to achieve this, the Systemic Anti-Cancer Therapy Data Set has a branching structure which links the initial data fields, which will remain constant during the treatment, with detail of each Systemic Anti-Cancer Therapy Drug Regimen, Systemic Anti-Cancer Therapy Drug Cycle and Systemic Anti-Cancer Therapy Drug Administration.  At the completion or cessation of a Systemic Anti-Cancer Therapy Drug Regimen, the outcome section must link back to all previous fields. It must be possible to reconstitute details of each PATIENT’s sequential management from the serial downloads received.

All NHS Trusts and NHS Foundation Trusts providing Systemic Anti-Cancer Therapy Services are required to submit monthly data downloads to an agreed timetable, two months in arrears. These data must represent all treatment activity in the month period, including Systemic Anti-Cancer Therapy Drug Regimens started and completed or ceased in the REPORTING PERIOD.

The data repository is hosted by the National Cancer Registration and Analysis Service (NCRAS) and the data is held under their section 251 of the National Health Service Act 2006.

Data downloads is by csv and will uniquely identify the Health Care Provider.
