The Toledo Blade reports that Ohio's ProMedica Bay Park Hospital recently began notifying 594 of its patients that a former employee inappropriately accessed their records between April 1, 2013 and April 1, 2014.

According to NBC24, the information accessed by the employee included the patients' names, birthdates, diagnoses, attending physicians and medications.

The employee was fired immediately after the discovery of the breach.

"ProMedica Bay Park Hospital has completed an internal investigation and is taking precautions to prevent any further health information breaches," the hospital said in a statement. "This includes additional training for employees to ensure they understand and follow patient information access policies."

All those affected are being offered a one-year membership in an identity theft protection service.
