Adventist Health System faces a class action lawsuit seeking damages for failure to safeguard the HIPAA - protected information of 763,000 patients at several of its hospitals in Florida . At the heart of the lawsuit is a breach that involved a former emergency department worker of Florida Hospital Celebration . Over a two - year period from 2009 to 2011 , the worker improperly accessed the electronic records of more than 763,000 patients treated at several Florida Hospital locations and sold personal information on about 12,000 patients to a co - conspirator , law enforcement officials say . That information was used to solicit legal and chiropractic services for patients involved in motor vehicle accidents , according to law enforcement officials ( see : Prison Time for Health Data Theft ) . ;
