An unencrypted desktop computer with the personal information of 3,780 patients was stolen from a Temple University physician’s office in July.

The computer, which resided in the department of surgery, was nabbed during a break-in, according to the Inquirer. Patients’ information, including their names, ages, billing codes and, in some cases, the name of their referring physician, was stored on the computer.

The theft was reported to police, authorities, the U.S. Department of Health and Human Services and affected patients. Victims may also sign up for a year of free identity-monitoring services.

The university said it has taken steps to prevent future thefts, including increasing physical surveillance, improving security measures for desktops and further educating employees about precautions they should take.
