The covered entity (CE), Yale University, discovered in September 2018, that it sent letters to wrong addresses due to a collating error, affecting 1,102 individuals. The types of protected health information (PHI) involved in the incident included demographic and clinical information. OCR reviewed the CE’s policies and procedures related to the breach and was satisfied that they were in compliance with the Privacy Rule. Following the breach, the CE sanctioned and retrained employees and updated its mailing list procedures and forms so as to prevent a similar type of error happening in the future. OCR obtained assurances that the CE provided breach notification to individuals affected by this breach and the media in accordance with the Breach Notification Rule.
