Baptist Health says its privacy office has recently learned that a South Miami Hospital employee inappropriately accessed 834 patient records.
According to the hospital, the records, dated from June 2011 through February 2012, included patient names, dates of birth and Social Security numbers.
The breach came to light during a collaborative investigation with federal law enforcement officials.
The hospital said the investigation showed that the employee disclosed information to individuals involved in filing fraudulent tax returns.
The South Miami Hospital employee has been terminated, and efforts are underway to prosecute the individual to the fullest extent possible, said the hospital.
For those that would like to contact the hospital, Baptist Health has set up a dedicated hotline for patients affected by the breach. Patients may call 1-866-33-HIPAA (44722) or email Privacy@BaptistHealth.net.
