An external hard drive containing ePHI of 2,773 individuals was stolen. The ePHI included first and last name, medical record number, date of birth, laboratory test information data, and some social security numbers. CE advises OCR that notice to the individuals went out April 13 and 14, 2010. The media (St. Petersburg Times) was notified. CE added emails will now be password protected and encrypted. As a result of the loss, CE has initiated an encryption project to encrypt external hard drives and related media. \ \
