OCR opened an investigation of the covered entity (CE), Montefiore Medical Center, after it reported three unencrypted desktop computers were stolen that contained the electronic protected health information (ePHI) of 23,753 individuals. The ePHI included names, medical record numbers, dates of birth, parent or guardian contact numbers, asthma diagnoses, vaccination information, and number of visits to the school health clinic. Upon discovery of the breach, the CE filed a police report and provided breach notification to affected individuals, HHS, and the media. As a result of OCR's investigation, the CE updated its building alarm to include additional motion sensors and installed surveillance cameras. Further, the CE encrypted all of its computers, advised that no ePHI is stored on desktop hard drives, removed all ePHI from its computers, and stored ePHI on the centralized secured network servers. The CE also revised its policy and procedure on password management and provided training to all staff on its new policy.
