Description:
The purpose of the Radiotherapy Data Set is to:
- collect consistent and comparable data across all NHS acute trust providers of radiotherapy services and all private facilities where delivery is funded by the NHS
- provide nationally comparable data to inform the planning, provision and commissioning of radiotherapy services across the NHS.
It has been a mandatory standard since April 2009 and collects information for every patient receiving treatment of:
- external beam radiotherapy (teletherapy)
- brachytherapy
- proton therapy
- radioisotope therapy (including radioiodine)
- molecular radiotherapy.
Providers of radiotherapy services to the NHS are required to provide a monthly return to Public Health England on all activity.
The changes introduced by this release include:
- the ability to structure the data into pathways, including specific sections for:
- an episode
- a prescription
- a plan
- an exposure
- an attendance
- the addition of:
- SNOMED CT
- unique radiotherapy coding
- the measurement type to support the prescribed and the actual absorbed radiation dose
- improved recording in respect of:
- proton therapy
- clinical trials that have a component of radiotherapy delivery included
- treatment intent
- route of admission
- radiotherapy treatment type
- specialist radiotherapy treatments
- a new way of recording consultant information
- the removal of the intention to change to xml submission
- the addition of choices for linkage and radioisotope.
Other data items have been given better descriptions, amended formats or updated attributes to help improve both the data quality, ascertainment and linkage of data through the data set.
