CPRD GOLD RTDS August 2021

Cancer data contain data provided by Public Health England (PHE) via the National Cancer Registration and Analysis Service (NCRAS). Linked NCRAS CPRD datasets include the National Radiotherapy Dataset (RTDS) dataset which contains records of radiotherapy services provided since April 2009, including teletherapy and brachytherapy. All radiotherapy delivered in England to patients in NHS facilities, or in private facilities where delivery was funded by the NHS, is included. Brachytherapy delivered for the treatment of non-malignant disease, radiotherapy delivered using unsealed sources, and non-therapeutic exposures delivered using radiotherapy machines (e.g. imaging) are not included. NCRAS data are subject to additional data governance requirements and any researcher proposing to use these data should discuss their NCRAS requirements with CPRD’s Observational Research team prior to protocol submission. Requests for NCRAS Cancer Registration data access are subject to prior protocol approval. Further information is available at https://www.cprd.com/linked-data. Coverage is for patients with tumours recorded in the cancer registration data from April 2021 to December 2018.
