Electronic health record linkage in the main STRIDES trial
To understand the health of participants in the STRIDES BioResource—and to track how this changes over time—we use medical and other health-related records. The National Health Service (NHS) doesn’t have a single record system and thus information needs to be obtained from various sources to build-up a complete picture. This page describes the different types of data, how we access the data and how we keep the information safe. Each application for data access goes through an approval process for compliance with ethical, legal and confidentiality requirements.
Participants provided Study Team with permission to access medical and other health-related records when they joined the STRIDES BioResource. Information from these records is retrieved using an NHS number, name and date of birth.
A single table linking each participant’s anonymous study identification number to their NHS Blood and Transplant (NHSBT) Donor Number, NHS number and other information that directly identifies them is stored in a separate, password protected location which may only be accessed by designated study data managers. This system is managed by the University of Cambridge School of Clinical Medicine and complies with NHS data protection standards. You can read more here.
The ‘link table’ is used to retrieve relevant health information from medical and other health-related records. The retrieved information is ‘de-personalised’ by removing any directly personal details such as name, NHS number or address and replacing them with an unique anonymous study identification number. The de-personalised information is then stored in a restricted-access, study database together with other information collected during the study.
Access to the study database is password protected and is only available to named researchers working on the studies under the direct supervision of the senior scientific investigators. Anonymised data may also be used for other medical and health-related studies which have relevant scientific and ethics approval.
We currently receive data about:
- Deaths and cancer diagnoses from NHS Digital
- Hospital treatment (Hospital Episode Statistics) from NHS Digital
- General Practice (GP) records from NHS Digital, specifically for COVID-19 related research
- COVID-19, including diagnosis and outcome, from Public Health England and the Intensive Care National Audit & Research Centre
Information from these records is retrieved using an NHS number, name and date of birth.
We intend to retain the data as a long-term research resource. This is subject to funding, data sharing agreements with external data providers and participants’ right to withdraw.
We plan to extend the range of data in the future to include more data from NHS Digital, Public Health England and other data providers. We will update this page as more data is obtained.
Data controller and legal basis for data processing
The University of Cambridge is the Data Controller for the Blood Donors Studies BioResource. We process personal data for scientific research purposes as part of the University of Cambridge’s public task under articles 6(1)(e) and 9(2)(j) of the General Data Protection Regulation (GDPR). The public interest nature of the research was assessed when reviewed by a Research Ethics Committee and the public bodies providing the funding.
Health data (for example, the datasets received from NHS Digital) is classified as a special category of personal data under the GDPR.
