What happened

In October 2026, Johns Hopkins Bayview Medical Center in Baltimore, Maryland began notifying patients that their health information may have been improperly shared after a staff member uploaded a spreadsheet of patient information to a public artificial intelligence (AI) tool that the hospital had not approved for that use.

According to published reports, the incident occurred and was discovered on September 21, 2026. The spreadsheet covered patients admitted and treated between May 2026 and September 2026. The information that may have been involved includes:

Patient names
Dates of admission and treatment
Medical record numbers and account numbers
The department that provided treatment
Medications given
Names of providers

The hospital has stated that Social Security numbers and financial account details were not included. Approximately 3,182 patients are reported to be affected. Notification letters began to be mailed on October 22, 2026, and include an offer of 12 months of complimentary credit monitoring. You may want to review your medical and insurance statements for services you did not receive.
