ProMedica Bay Park Hospital is notifying nearly 600 patients that their health information may have been compromised. Toledo News Now reports that Bay Park Hospital found that an employee accessed the records of patients that the employee was not directly treating without a valid business reason. ProMedica says it doesn't believe any financial data was accessed, but names, dates of birth, diagnosis and other clinical information may have been accessed. The hospital says they are taking precautions to ensure further data breeches do not happen.
