11 Years of Maternity Records Lost in NHS IT Error
Human error overwrites critical healthcare data during routine database maintenance.
1Critical maternity data erased
Nottingham University Hospitals NHS Trust lost 11 years of maternity records due to an IT error during routine database maintenance on August 18. The incident occurred when technicians used an unmodified script intended for radiotherapy records on the maternity database instead. This resulted in complete overwrite of records spanning September 2011 to November 2022, including viewing history logs showing who accessed patient files.
2Failed recovery efforts
Despite immediate escalation and working with external specialists, NUH couldn't fully restore the viewing history data. While patient care information like notes and test results was recovered, the hospital cannot confirm which staff members accessed specific maternity records during the 11-year period. This creates potential accountability gaps for historical cases under police investigation regarding maternity care quality.
3Compounding existing scandals
The data loss occurs amid an ongoing police investigation into NUH's maternity services, where over 500 cases of potentially avoidable harm or death were identified. A June 2023 review cited systemic failures including understaffing and poor training. Separately, police are investigating whether this IT incident relates to a June 2025 case where hundreds of maternity records were possibly deleted intentionally.
4Technical root cause
The error stemmed from using pre-written database scripts without modifying critical settings before execution. These scripts, designed for radiotherapy reporting, were mistakenly run on maternity databases. NHS systems often rely on such reusable scripts for routine operations, creating potential points of failure when change management protocols aren't strictly followed during database maintenance procedures.
5Patient impact assessment
NUH claims the incident doesn't affect current patient care, with no evidence of inappropriate data access. However, families involved in the broader maternity scandal expressed distress about record security. The hospital completed a patient safety investigation and implemented unspecified technical controls to prevent recurrence, though details remain undisclosed.
6Legal implications
Nottinghamshire Police are determining if this data loss impacts their criminal investigation into maternity care failures. While no crime has been identified in this IT incident, it complicates evidence collection for historical cases. The force is attempting data recovery, mirroring their success in restoring intentionally deleted records in the 2025 case.
7Institutional response
Chief Digital Officer Andy Callow publicly apologized while emphasizing restored clinical data integrity. The hospital's transparency in disclosing the error contrasts with its ongoing maternity care controversies. This incident highlights vulnerabilities in healthcare IT systems handling sensitive historical data, particularly during routine maintenance operations.
8Broader system vulnerabilities
This case exposes critical risks in healthcare database management where single human errors can erase years of records. It underscores the need for better change control protocols, script validation processes, and immutable audit trails in hospital IT systems, especially for departments already under scrutiny for patient safety concerns.
