The mishap occurred on August 18, when staff performing routine technical work on a radiotherapy database used a set of pre-written instructions that had previously been run against another hospital system. A critical setting was not changed before execution, causing the script to overwrite the trust’s old Medway maternity records database instead of the intended target.
Nottingham University Hospitals (NUH) described the incident as human error and said it was escalated within minutes of discovery. The trust confirmed it has recovered the clinical information needed for patient care, including notes, observations and test results, and emphasised that current maternity services and patients are unaffected. No patient information was accessed or used inappropriately as a result of the error.
However, the trust has been unable to fully restore the historical record showing who viewed maternity records during the 11-year period. External specialists were brought in and alternative data sources were searched, but the complete access history remains missing. This means NUH may now be unable, in most cases, to establish whether a particular person looked at a patient’s maternity record between September 2011 and November 2022.
The Information Commissioner’s Office has been notified, and Nottinghamshire Police is assessing whether the loss has any impact on Operation Perth – its investigation into deaths and serious injuries involving mothers and babies at Nottingham City Hospital and Queen’s Medical Centre.
Andy Callow, chief digital and information officer at NUH, apologised to affected women and families. “The information needed to support patient care has been restored and there has been no impact on current maternity services or the care provided to women and babies today,” Callow said. “However, to date, we have been unable to fully restore the historical record showing who viewed maternity records between September 2011 and November 2022.”
The trust has completed a patient safety incident investigation and strengthened its technical controls and processes to prevent a recurrence.
