NorthShore University HealthSystem said the personal information of about 348,000 people has been exposed in a breach involving one of the health system’s vendors earlier this year.
NorthShore recently sent a letter to those affected saying information including their full names, birth dates, addresses, phone numbers, doctors' names, doctors' offices, and dates of admission and discharge may have been exposed.
No patient medical records were accessed, NorthShore spokesman Jim Anthony said in a statement.
NorthShore is recommending that affected individuals monitor their personal accounts for suspicious activity.
