Introduction
The Radiotherapy Data Set (RTDS) is the national standard for collecting radiotherapy data in the NHS.
This dashboard presents the number of attendances by machine ID may total more than total attendances. This is due to some patients being treated on two or more machines within the same attendance.
Acknowledgement
This work uses data that has been provided by patients and collected by the NHS as part of their care and support. The data is collated, maintained and quality assured by the National Disease Registration Service, which is part of NHS England (NHSE).
Radiotherapy Dataset
The Radiotherapy Dataset (RTDS) standard collects consistent and comparable data across all NHS Acute Trust providers of radiotherapy services in England, and additional NHS centres delivering radiotherapy services in Scotland and Wales.
This data can be used to provide intelligence for services planning, commissioning, clinical practice and research and operational provision of radiotherapy services across the UK. All NHS radiotherapy activity data is collected including external beam radiotherapy and brachytherapy.
Data use and limitations
This dashboard provides access to operational and clinical data produced by the National Disease Registration Service (NDRS). The data is derived from sensitive patient level information and is shared to support data quality improvement, service planning, and performance monitoring within health and care organisations.
While the data is de-personalised, small numbers or rare conditions may increase the risk of re-identification. Users must therefore take care when interpreting and sharing outputs.
By accessing this dashboard, users are expected to act in accordance with NHS information governance principles, the Caldicott Principles, and applicable data protection legislation, including the Data Protection Act 2018 and UK GDPR.
Users must ensure that:
- data is used only for legitimate health and care purposes
- data is not used to identify individuals, either directly or indirectly
- data is not shared, reproduced, or used outside authorised environments or without a clear business need
- any onward sharing is carefully considered, balancing the risk of disclosure against the intended benefit, and only shared with appropriate organisations or individuals
- outputs are interpreted appropriately, taking account of limitations in completeness, timeliness, and accuracy
- published or shared data relates only to their own organisation or is benchmarked against England-level data
- any published outputs meet anonymisation standards
- advice is sought from local Information Governance teams or a Caldicott Guardian where there is any uncertainty or risk
Permission must be sought in advance of any publication that includes Welsh and/or Scottish data from:
When publishing data please ensure to follow the guidance for staff and stakeholders about how and when to acknowledge the use of NDRS data.
If you have any concerns about data use, interpretation, or disclosure risk, please email the NDRS team at to nhsdigital.ndrsdatahub@nhs.net

We intend these reports to be as useful as possible to the community, and aim to continue to adapt and improve them to meet user needs.
As such, it would be very helpful for us if you were able to send any feedback, positive or negative, to the RTDS Helpdesk at RTDS.helpdesk@nhs.net
