The data collected is individual level data consisting of patient data from the UK Transplant Registry (UKTR); the Hospital Episode Statistics database for England ((HES) information about hospital care and appointments), the civil registration (mortality) database, and the National Cancer Registration and Analysis Service ((NCRAS), the cancer registry in England) from NHS England (a trusted third party). The data from the UKTR and NCRAS is linked by NHS England to identify patients who have received an organ transplant and have either been diagnosed with cancer, or not.
The data is pseudonymised, which means that any information which would enable an individual to be directly identified has been removed and replaced by a unique identifier (a large number). NHS England hold the key for the pseudonymised identifiers. NHS England will then confirm to the UKTR which patients are matched so that UKTR and NHS England can extract the relevant health data from their datasets. For patients identified as having an organ transplant and a cancer diagnosis, NCRAS will provide information about each patient’s tumour (such as date of diagnosis, type of tumour and grade) as well as information about the cancer treatment they have received.
The data from UKTR and NHS England (NCRAS, deaths and HES) will be shared with the University of Birmingham with only a pseudonymised ID and direct patient identifiers removed. This makes the possibility of linking the data back to an individual employee or their employment records highly unlikely. The University of Birmingham cannot identify and contact individual members of the cohort.
