Grey Bruce Health Services says an investigation shows a former employee inappropriately accessed the electronic medical records of 246 patients during a seven year period.
Spokesperson for GBHS, Mary Margaret Crapper, tells Bayshore Broadcasting News the investigation began last September after the hospital initially heard about four patients who's information had been accessed.
Their investigation into the privacy breach went back seven years, from January 2008 to September 2015, which is the amount of time health records have been stored via a computer system instead of on paper.
Crapper says the staffer involved is no longer employed with Grey Bruce Health Services, an organization that operates hospitals in Owen Sound, Markdale, Lion's Head, Meaford, Southampton and Wiarton.
The privacy breach has been reported to the Ontario Information and Privacy Commissioner's office.
Crapper says privacy breaches are not tolerated at GBHS, and all patients involved in the breach have been notified.
She adds the breach does not impact any test results or diagnosis.
At this point, Crappers says it appears the breach was more of a curiosity by the employee and the records were not altered.
