Loma Linda University Health (LLUH) is providing notice of an incident that may have involved certain patients' protected health information.

On May 25, 2026, during an Institutional Review Board (IRB)-approved research study, a file containing limited patient information was inadvertently uploaded to an external artificial

intelligence (AI) platform. Upon discovery, LLUH promptly initiated an investigation and requested deletion of the information from the platform.

The information involved may have included a medical record number, date of birth, and limited clinical information related to orthopedic care. Social Security numbers, financial information,

insurance information, and complete treatment records were not involved.

LLUH takes the privacy and security of patient information seriously and is reviewing its policies, procedures, and workforce training regarding the use of external technologies, including AI tools.

Individuals who believe they may be affected or who have questions may contact LLUH's Office of Corporate Compliance at 909-651-4210 for additional information.
