“On December 14, 2012, we learned that a computer virus may have allowed an unauthorized person to access a Froedtert Health employee’s work computer account,” the hospital states in a notice to patients. “We found no evidence that any unauthorized person accessed any personal information or medical records. As a precaution, we felt it was important to tell you this occurred.”
A forensics investigation did not definitely determine if information was accessed. Information in the account included names, addresses, telephone numbers, dates of birth, medical record numbers, insurer names, diagnoses, and an unspecified number of Social Security numbers.
The hospital has set up a call center for affected patients and is offering paid credit protection services, according to a spokesperson.
