The blame for inadvertent disclosures caused by a computer error can only be determined by an investigation into the event. Covered Entities and Business Associates are required to implement administrative, technical, and physical safeguards to prevent computer errors. If the inadvertent disclosure is attributable to a Covered Entity or Business Associate failing to implement safeguards – or failing to provide instruction on how to use the computer securely – the employer is at fault. If, however, the inadvertent disclosure is attributable to operator error, the employee is at fault.
