## Summary

Johns Hopkins Bayview Medical Center alerted about 3,182 patients on October 22, 2026, after a staff member uploaded a spreadsheet containing their protected health information to an unapproved AI tool on September 21. The data included names, admission dates, medical record numbers, account numbers, treatment details, and provider names—but excluded Social Security numbers and financial data—covering patients treated between May and September 2026. The hospital confirmed the incident during an internal review and took steps to delete the data from the third-party tool, though it did not specify how long the information may have been exposed or accessed by unauthorized parties.

The hospital is using the breach to update its policies and staff training, restricting the use of unapproved AI tools and emphasizing compliance with protected health information protocols. Affected patients receive 12 months of free credit monitoring through Experian IdentityWorks and can contact a dedicated call center (1-833-931-7766) for questions. The incident highlights ongoing risks of improper AI tool usage in healthcare settings, where sensitive data must be handled with strict controls.
