Two laptop computers containing the electronic protected health information (ePHI) of approximately 5,450 individuals were stolen from the CE. The ePHI included patient names, dates of birth, and social security numbers. The CE provided breach notification to all affected individuals, HHS, and the media. As a result of OCR's investigation, the CE installed encryption software and increased physical security.
