The IT department turned on the switch to a BA HIE without notifying patients of the exchange or obtaining authorization. The interface transmitted the PHI of 654 individuals. The PHI disclosed included patient names, addresses, dates of birth, social security numbers, other identifiers, diagnosis/conditions, medications, lab results, other treatment information and financial information. Following the breach, the CE revised the IT process, created a checklist that included notifying the affected departments and provided additional training to IT and registration employees. \
