OCR description
The covered entity (CE), Kaiser Foundation Hospital - Orange County, misplaced a portable computer drive containing the protected health information (PHI) of 49,000 individuals. The types of PHI involved in the breach included names, dates of birth, and medications. The CE provided breach notification to HHS, affected individuals, and the media. Following the breach the CE began phasing out the use of flash drives or similar devices and initiated a plan to replace computers, and store PHI on secured servers behind the CE’s firewall. OCR provided technical assistance on conducting a security risk analysis, and as a result of its investigation OCR informed the CE that it is required to conduct an enterprise-wide security risk analysis.
