Concerns Raised as Chinese Researchers Access UK Health Data
Reports indicate that research facilities in China have gained access to sensitive health data from the National Health Service (NHS) from a major study in the United Kingdom. The UK Biobank, a large-scale biomedical database, holds anonymized health and genetic information from half a million volunteers across Britain, raising questions regarding data security and international access.
Access to Patient Data by Foreign Researchers
Health authorities have affirmed their commitment to “protect NHS data” following reports detailing access to patient information by overseas researchers. NHS officials emphasized that formal authorization is mandatory before any data sharing occurs. The UK Biobank facilitates global research collaborations, allowing researchers worldwide to apply for data access to advance medical understanding. Notably, academics based in China account for one in five approved applications to utilize this data, positioning them second only to researchers in the United States, as reported by the Guardian. Numerous studies by Chinese researchers using UK Biobank data have appeared in respected scholarly publications over the past year, including the British Journal of Sports Medicine, BMJ Evidence Based Medicine, Heart, and Neurology.
Research Findings and Data Sensitivity
Research outcomes derived from this data have been presented at leading international health conferences, such as the European Society of Cardiology Congress. These studies encompass diverse health areas, including investigations into sleep patterns, dementia, and heart failure.
Emma Lagerstedt, representing the Understanding Patient Data organization, highlighted the inherent sensitivity of data originating from GP records, even when patient identities are removed.
She asserted, “Individuals who participate in extensive cohort studies rightly anticipate robust data protection measures and expect researchers to adhere to the highest ethical principles. Considering the delicate nature of GP data and broader public concerns – such as those related to national security – enhanced transparency is paramount.”

“This necessitates clear and readily understandable information detailing the authorization process for data access, the identities of those who have accessed it, and the specific purposes for which it is used.”
“Demonstrating this level of openness and trustworthiness is crucial for maintaining public confidence in the utilization of patient data for research endeavors.”
NHS England and Data Protection Measures
A spokesperson for NHS England stated: “NHS England is collaborating closely with Government bodies, General Practitioners, privacy advocates, and patient representatives to facilitate the sharing of GP data for explicitly approved research studies, but only in cases where individual patient consent has been expressly granted.”
“Whilst legal directives would be necessary prior to any data sharing or agreements, NHS England remains dedicated to ensuring appropriate safeguards are in place to protect NHS data.”
UK Biobank Defends Data Access Protocols
Professor Sir Rory Collins, Principal Investigator and Chief Executive of UK Biobank, commented: “Half a million individuals volunteered to join UK Biobank to enable scientists globally to address conditions such as cancer and dementia.”
“All our volunteers have provided explicit consent for researchers to analyze their de-identified health information, and many have stressed the importance of incorporating their GP data into these analyses.”
“We adhere to Government guidelines regarding data access to UK Biobank and maintain robust security protocols, endorsed by the Government and our funding bodies, to ensure data safety.”
Rigorous Vetting Process for Researchers
UK Biobank clarified that all researchers and academic institutions undergo “thorough vetting” prior to application approval.
To date, over 15,000 peer-reviewed research articles have been published using UK Biobank data in the 13 years since global researcher access was initiated.
Professor Patrick Chinnery, Executive Chair of the Medical Research Council, affirmed that the discoveries arising from UK Biobank-supported research demonstrate the effectiveness of a “managed access model.” This model allows international researchers to expedite the identification of new drug targets, treatments, and diagnostic tools.
He added, “Their data protection measures are extensive, and we have complete confidence in their implementation.”
Reassurances on Data Security and Access Controls
Nicola Perrin, Chief Executive of the Association of Medical Research Charities and a UK Biobank board member, stated that recent press coverage suggesting unfettered Chinese access to NHS data is inaccurate and “simply not the case.”
She further explained: “It is crucial to emphasize that all access requests are subjected to stringent application and approval procedures. Importantly, GP data will not be disseminated globally; data can only be accessed within UK Biobank’s Research Analysis Platform – a secure data environment.”
Government Stance on Data Protection
A Government spokesperson stated: “Protecting national security is fundamental to all our operations. We have rigorous security protocols in place to guarantee the protection of all sensitive UK health data.”
“UK Biobank data sharing has been operational for over a decade and consistently involves de-identified data, removing direct and indirect identifiers.”
“Data sharing is governed by exceptionally high standards and is exclusive to legitimate researchers for specific research purposes. Access is restricted to a secure digital environment, preventing the downloading of GP data copies outside of this secure zone.”
